Typo redirect in Firefox

Hello. I was attempting to correct a typo in the Firefox address bar and accidentally overtyped the entire URL with the single letter "s" and pressed enter. I was surprised when I was taken to craigslist.org. I intentionally repeated the action, careful not to select any of the drop-down history items and received the same results. I have visited the craigslist a couple of times in the past, but have never intentionally downloaded anything from there. Is it possible that the site installed something without my knowledge? I took a look at my Firefox add-ons and didn't see anything suspicious. Does anyone else get similar results? Any idea why this behaves this way? Thanks. -- Tcncv (talk) 02:27, 27 February 2009 (UTC)

I tried to replicate that just know but didn't quite succeed. Instead, I was taken to a list of Google hits for "s", the first of which -- for some strange (and I'd cynically guess paid-for) reason -- was Craig's List. The resemblance to your result doesn't seem coincidental. Doing the same for the not-quite randomly selected string "tcncv" takes me not to Google instead to some outfit called "twincitiesnightclubs.com". How does it work for you? -- Hoary (talk) 02:35, 27 February 2009 (UTC)

(e/c) Nope, you didn't download anything. Typing in something in the address bar is like doing an "I'm feeling lucky" search on Google. It does a google search for the term (or letter) and takes you to the first result. In this case, the first result in a google search for "s" is craigslist. flaminglawyer 02:37, 27 February 2009 (UTC)

Thank you. Is there any way to disable this behavior? I tried changing search engines (I chose Wikipedia) and even removed the search box from the right side of the toolbar, but I still get the same result. It's not a big deal, but I prefer not to have an application that redirects typos to the highest bidder. -- Tcncv (talk) 02:59, 27 February 2009 (UTC)

Use about:config to set keyword.enabled to "false" (or change keyword.URL to your preferred search). – 74  03:10, 27 February 2009 (UTC)

Excellent. Thank you. -- Tcncv (talk) 03:38, 27 February 2009 (UTC)

Just as an aside, this is an excellent feature! It makes typing in websites much faster. If you want to go to amazon, just type "amazon", if you want to go to wikipedia, just type "wikipedia" (although that takes you to the international portal). It's WAAAAY cool once you start using it regularly. For instance, has this situation ever happened to you: "Ohh, I want to go to Reddit! Wait, what is it? reddit.net? reddit.org? reddit.us? reddit.com?", and then you have to land on a bunch of domain-squatters sites, giving them ad impressions and stuff. No need to, just type "reddit"! Another example: "I'm thinking of applying to Brandeis University! Let's go to their website! How's it spelled again? Brandyce? Brandice? Brandeis? And is it brandeisuniversity.edu, brandeis.edu, brandies.com, brandyceuniversity.com, brandice.edu, brandyce.org?" etc, etc. No need to worry, type in any of those spellings, and it takes you right there.

Seriously, it's a great feature once you start to use it. And it's not like Google is involved every time you type something in to the address-bar, if you type in a regular ol' URL, it'll just go there. It only activates when you type in a normal human-language word or phrase. I don't even bookmark stuff anymore, I just use that + the awesomebar. Give it a shot, I bet you'll love it!

Installing 2nd hard drive

My XP machine bit the dust, but I'm fairly certain my SATA hard drive is okay (fingers crossed). I've now got a Vista machine and want to hook up my old hard drive to access some files. Is this just a matter of hooking up the power and data cables, then doing something in the BIOS or control panel somewhere? Do I need to buy a data cable or is it in there? Clarityfiend (talk) 06:41, 27 February 2009 (UTC)

It seems so. SATA cable could be taken from XP machine. Usually adding an another HDD does not requires any changes in BIOS, so drive could be just plugged in. -Yyy (talk) 08:13, 27 February 2009 (UTC)

You are fortunate that it is SATA; if it was IDE, you'd likely have to alter some jumpers. Useight (talk) 17:15, 27 February 2009 (UTC)

Interact with an X session remotely

Hey all,

Say I have a desktop computer running some variety of UNIX (probably in practice going to be GNU/Linux) and X. A user has an X session open through the normal method (startx executed locally). Assuming I have root access to this computer, is there any way to control this X session (for example, running a program the graphical component of which would then appear within X, say to control MPlayer on my desktop from another computer on the network) using a command-line tool like SSH?

Yes, I know about VNC - it won't work very well for my purposes as the computer I'm hoping to RC from is a tiny EEE PC that doesn't even have X.

Thanks a lot, Aseld ^talk 12:02, 27 February 2009 (UTC)

VideoLAN has a simple http server that allows you to control it remotely. 87.114.16.126 (talk) 12:25, 27 February 2009 (UTC)

Many applications which make sense to "remote control" support some option for doing so. MPlayer, for instance, can accept commands from a "file" (which, in Linux, includes named pipes, etc.) with the "-input" command line option. Here's an example of MPlayer remote control; you can modify it to run as a command-line app, or just manually send commands to the input. – 74  16:57, 27 February 2009 (UTC)

How to put an upper limit on the size of webpage a browser will load?

Sometimes I find that as a result of surfing or googling my computer is downloading a huge webpage - usually a blog page, which may include several video files for example. This takes over the computer and makes it unusable for ten or twenty minutes - the red X to stop downloading does not work, the computer more or less freezes while the blogbloat page downloads. Only way to stop it is pressing Ctrl-Alt-Del and losing all open browser windows. Does any briowser allow you to specify an upper limit to the size of webpage loaded - so that it automatically stops loading when this limit is reached please? 78.149.170.123 (talk) 14:11, 27 February 2009 (UTC)

I'll be surprised if there is such a thing, but you might be interested in FlashBlock, which stops Flash videos from loading until you click on them. --Sean 15:01, 27 February 2009 (UTC)

Can you give the URL of such a page? Or, if you are (understandably) reluctant to go looking, the domain name of a site that has such pages? -- Hoary (talk) 15:05, 27 February 2009 (UTC)

I have looked but cannot find any in my History, perhaps because that page is not recorded when I press cntrl-alt-del. You may find one if you search for a popular subject that involves pictures - so try something involving celebrities for example. The problem is made much worse by some bloggers apparantly archiving several pages onto one huge one. Try googling for Celebrity Blog Archive for example - although I would prefer not to get in that trap again. 89.241.154.51 (talk) 21:09, 1 March 2009 (UTC)

Large pics are usually what takes my computer down. However, by the time you realize there's a problem it's too late to stop it. This is part of the much larger problem of apps not being smart enough to figure out that the object they are trying to load will exceed the available memory. They should refuse, or at least warn you, in such cases. One workaround option is to use a browser like Firefox, which can restore your tabs/windows to their previous states when it's next restarted (except for some Flash games and such). StuRat (talk) 15:57, 27 February 2009 (UTC)

Side note... The web browser on the PSP will warn you if the page won't fit in memory and offer to show it in "memory save mode". -- kainaw™ 16:13, 27 February 2009 (UTC)

The HTTP specification supports "Range" headers, which can be used to limit the size of HTTP responses (though not all servers support them). You might be able to add such a header to your browser's default request. However, in my experience webpages are quite cancel-able, either with the 'X' or by hitting the 'stop' or 'back' button (now conveniently located on keyboards and mice). If your current browser doesn't behave reasonably I'd suggest switching to a better alternative. – 74  17:29, 27 February 2009 (UTC)

In my experience it isn't that they can't be canceled, but that, by the time you get the idea that it needs to be canceled (say due to the browser slowing to a crawl), it's already too late to save the session. Thus the need for an automated method of checking the size of a downloading page and stopping it BEFORE all available memory has already been used up. StuRat (talk) 21:38, 27 February 2009 (UTC)

I wonder if it is possible to change the priorities in windows or explorer (very very hazy idea of what is involved) so that the computer always responds to user commands, and never, as happens now, ignores user commands as its too busy loading a webpage? 89.241.154.51 (talk) 21:09, 1 March 2009 (UTC)

I wish it were possible to do that, but I'm rather skeptical. StuRat (talk) 19:37, 3 March 2009 (UTC)

Sounds to me like your computer is a little bit dated. If it's easily possible to add some RAM to your machine it might improve the performance in those cases significantly.204.16.236.254 (talk) 00:20, 5 March 2009 (UTC)

WHY ISN'T MY .MKV CONVERTING PROPERLY?!?!!!!!!!!11@@!

I have an .mkv of My Neighbor Totoro. I want to stream it to my Xbox to enjoy a delightful cinematic experience, but Xbox doesn't natively support .mkv, only .avi and .wmv. I want to convert the movie to AVI so i can watch it. I tried using Avidemux to re-encode the movie using Xvid and I converted the audio to AAC, then saved in the the AVI container format.

MKV is just a container format; the video (and audio) is encoded in one of a large number of codecs. Your MKV file is encoded in a codec that Avidemux doesn't know. So if you encoded it yourself (e.g. from a DVD) then what you're doing wrong is encoding it with the wrong codec, and you should experiment with your encoding application's settings. If you didn't encode it yourself then you should delete the file and go buy it on DVD. 87.114.16.126 (talk) 17:59, 27 February 2009 (UTC)

error message on football website

I load up Swansea FC website and open the SwansWorld link. I log in and try to open the Match Highlights link. I can open the page but get an error message at the bottom of the screen. I select a match and click Play. It open sup a new page and says Now Playing but there is no picture or sound. Can you explain why this happens and offer a remedy?Silverlining99 (talk) 19:48, 27 February 2009 (UTC)

In cases like this, it's usually useful to provide us with the error message in question. It probably happens because something isn't working right on the website (hence the error message). Or, possibly, because you need to install a plugin, which is probably mentioned in the error message, if this is the case. I checked out the section of the site myself, and it seemed to work, but of course I'm not a subscriber, and it's possible that we're not seeing the same things at all. In any case, I did see and hear a promotional video play in the "Match Highlights" section. That may simply mean that they fixed the problem with the site. -- Captain Disdain (talk) 10:22, 28 February 2009 (UTC)

Complexity Class/Average Time

Consider the following problem: you are given a set of n points in the plane and want to find the largest distance between two points. Does anyone know what the complexity class of this is? What the average time this can be found in is/worst time, etc.? Phoenix1177 (talk) 00:32, 28 February 2009 (UTC)

The distance between two points in 2D is sqrt((X₁-X₂)²+(Y₁-Y₂)²). To find the maximum distance in a set of points I would normally find the square of the distance between every point pair (plug them into the previous formula but omit the square root). This way the distances can be compared without the inefficient square root operation. Only once the maximum was found would it be necessary to do the square root to find the actual distance. This brute force approach could work well for up to thousands of points.

However, this approach wouldn't work so well if you had millions of points. This would require trillions of operations. In such a case, a more sophisticated approach would be needed. Perhaps a first pass could find the minimum X, maximum X, minimum Y, and maximum Y from the set of points. This could be used to find the center point. The square of the distance of every point from this center could then be found and maybe the farthest 1000 stored in a list. The farthest 2 points would likely be in this list, reducing processing time dramatically. I don't know if I could actually guarantee that the farthest two points would ALWAYS be found by this method, though. StuRat (talk) 04:56, 28 February 2009 (UTC)

The pair of points farthest away from each other (or one such pair, if it is not unique) will be guaranteed to be both on "corners" of the convex hull of the points. So one thing you can do is find the convex hull, which can be done in O(n log h) (where h is the number of points in the hull), and then kind of iterate around the hull on opposite sides at the same time, calculating the distances between points on the hull that are approximately "opposite" each other; this will take O(h), so this process is O(h + n log h), which is also O(n log n). --Spoon! (talk) 09:00, 28 February 2009 (UTC)

But how do you know if points are on opposite sides before you determine their distance ? StuRat (talk) 14:41, 28 February 2009 (UTC)

Thank you for the response, I had worked out an algorithim that used the fact that figuring out if a point in the plane was inside of a given square was very easy(since you just need to compare x and y with numbers defining the square) to use squares ever increasing in size to rule out pairs of points. It was quite better than the basic approach of calculating all the distances and then comparing them; but I'm fairly sure the convex hull approach works better, probably much better.

Relatedly, it is obvious that I can look at a bunch of dots on a page, draw a circle around one, measure the radius, and see what points aren't in it; thus, determining what points are less than r distance away from the center point. However, computers seem forced to manipulate the problem numerically; my point is that humans can do this quickly, and I don't think they'd have any problem, outside of listing all the points, even if the size of the set got very large; so, does anyone know if there is a way to get a computer to approach the problem geometrically in the sense of a human above, it should be possible. Ultimately, we can manipulate circles, mentally, by treating the circle like a single object, is there any language that can manipulate geometric objects in this fashion (without breaking them down into a representation of points in the plane, basically, that can do this elementally). Phoenix1177 (talk) 17:59, 28 February 2009 (UTC)

I see what you mean. There do seem to be some simple tasks which computers just can't do very well. Determining which points are inside a circle is one of them. Another common example is inserting something into the middle of a list. If I want to insert a shirt into a clothes rack, I just push the rest of the clothes back and pop it in. But computers can't do this without "taking every other item after the insertion point off the rack and placing it back onto the rack in the new position".

Back to the circle problem, you could convert the point coords all to polar coords, centered on that target point, which would then make determining which were inside a given radius trivial, but this would take just as long as calculating the distance to each.

Perhaps it would help if you could sort the points geometrically first. Say you have points with coords between -10 and 10 for both the X and Y coords. You could place all points with an X value between -10 and -9 and a Y value between 1 and 2 in one list, for example. If you then determined that this box is not worthy of further consideration, you could eliminate all the points contained therein at once, instead of making that determination for every point individually.

It would help if you could give some specifics, like exactly how many points there are and what range of X and Y coords they cover, and if any of the points will share the exact same coords, and if the points will be evenly distributed or clumped together. Also, what kind of response time is needed and do you need to be absolutely certain to get the maximum distance, or is a "close approximation" usable ? And don't overlook my suggestion of omitting the square root operation until the very end, as this makes an absolutely huge diff in performance. StuRat (talk) 20:31, 28 February 2009 (UTC)

This is from Introduction to Algorithms (by CLRS), page 948-949: (hopefully it is not a copyright violation to quote it here)

Consider, for example, the two-dimensional farthest-pair problem: we are given a set of n points in the plane and wish to find the two points whose distance from each other is maximum. As Exercise 33.3-3 asks you to prove, these two points must be vertices of the convex hull. Although we won't prove it here, the farthest pair of vertices of an n-vertex convex polygon can be found in O(n) time. Thus, by computing the convex hull of the n input points in O(n lg n) time and then finding the farthest pair of the resulting convex-polygon vertices, we can find the farthest pair of points in any set of n points in O(n lg n) time.

--Spoon! (talk) 21:37, 28 February 2009 (UTC)

Thank you again for your responses. As for specifics: I am not so much interested in this single problem, I am more interested in finding what methods are fast at solving geometric based problems, then seeing how these differ from the slower ones. The main intention being that I believe that there is a very large difference in how humans approach geometric problems, symbolic problems, computational problems, etc.; basically, I think there should exist ways to mechanize the ideas underlying these approaches in a way that would be useful. Phoenix1177 (talk) 21:49, 28 February 2009 (UTC)

I think many of the limitations in how computers approach such problems are due to them using linear programs and single processors (or small numbers). Perhaps a massive parallel array of processors could solve such machine vision problems like this (finding all the points within a circle) more quickly. For example, a program running on each processor could analyze whether each point is within a circle or not, so all points could be analyzed simultaneously. StuRat (talk) 16:07, 1 March 2009 (UTC)

I agree with what you're saying. However, I think that the way our minds represent data is important; consider the example of expanding a circle, we focus in on the radius increasing; or consider the case of a square, when translating it mentally we treat it as if it were a point, when compressing/expanding it we treat it like a set of four numbers corresponding to side lengths; etc. The point is that the representation/focus we use has a tendency to be naturally suited to the task at hand; obviously, this is because we have a visual system, but, the underlying representations should be capable of abstraction(I love wishful thinking...:) Phoenix1177 (talk) 12:00, 2 March 2009 (UTC)

Agreed. The points are never stored in our brains as a set of coords, for example, but are first stored with their relationship to other objects. In our case, that means they are initially stored as "points within the circle", so no further calculations are required. While our brains seem to have a single train of thought, much like a computer, I don't believe this applies to our senses, which do process all inputs simultaneously. So, we need to mimic both the massive parallel neural network in our brains and the storage structure used to record the results, if we want our computer to be as fast.

Windows XP wireless trouble

Maybe someone can help : / I recently installed Windows XP on my Macbook with Bootcamp, but for some reason, Windows XP refuses to recognize my wireless internet. It asks for a dial-up connection, but that's it. I looked through, I believe, all the menus and preferences etc, but I can't figure it out. Thanks! Evaunit♥666♥ 07:49, 28 February 2009 (UTC)

What service pack do you have installed? I have had trouble with the wireless internet on Service Pack 1 and lower. Also, it may just be that your installation of Windows does not have the drivers for your wireless NIC, most likely due to it being a Macbook. You could try searching for the driver on the internet on a friends' computer, download the driver, put said driver on a flash drive, and transfer to your macbook. You would need to know the model of your wireless NIC in order to do this though. Good luck. Until It Sleeps 02:05, 1 March 2009 (UTC)

Replacing thumbnails with original image

Hi there, I'm looking for a way to use greasemonkey javascript to convert all links on a page from something like

website.com/thumb/001s.jpg
website.com/thumb/002s.jpg
website.com/thumb/003s.jpg
website.com/thumb/004s.jpg
etc

to

website.com/images/001.jpg
website.com/images/002.jpg
website.com/images/003.jpg
website.com/images/004.jpg

Please note that the image names I've given (001, 002, etc) are just examples and this would need to work for whatever the image name happened to be, and also not just for jpg but for png, gif, etc. So basically a page will load the full image instead of the thumbnail, but keep the image in the same size and placement on the page as the thumbnail. This is useful to me so that I can save a webpage and include the full images instead of having to download them individually later. Thank you so much to whoever can help me with this.

The url layout I posted above is pretty much the same for each image with just the name of the jpg changing and the directory for /thumb/ and /images/ etc. I did find this which does exactly what I want on almost any page, but it loads the images all over the place and not in their original locations and thumbnailed size. I know it's asking a lot, but could anyone with some javascript skills possibly write something like this for what I want? I would be eternally grateful. Again, thank you —Preceding unsigned comment added by 82.43.88.87 (talk) 20:57, 28 February 2009 (UTC)

Alright, here's a snippet of javascript that presumably meets your requirements:

function img_fix() {

	for( var i = 0, j = document.getElementsByTagName('a'); j[i]; i++ ) {

		// if an anchor tag links to an image file and contains an image tag, use the link href for the image tag src
		

		if (j[i].href && j[i].href.match(/[.](bmp|gif|jpe?g|png|svg)/) && j[i].childNodes[0] && j[i].childNodes[0].src) {

			j[i].childNodes[0].src = j[i].href; 

		}

		// otherwise, check if an included image tag's src contains "thumb" and replace it with "images"

		else if (j[i].href && j[i].childNodes[0] && j[i].childNodes[0].src && j[i].childNodes[0].src.match(/thumb/)) {

			j[i].childNodes[0].src = j[i].childNodes[0].src.replace(/thumb(nail)?s?/,'images');
		}

	}
}


document.addEventListener('load',function addButton() {

	// throw a link up in the corner

	if( !document.body ) { return; }
	var mydiv = document.createElement('div');
	mydiv.style.position = 'fixed';
	mydiv.style.top = '0px';
	mydiv.style.right = '0px';
	mydiv.style.width = '20px';
	mydiv.style.border = '1px solid #000';
	mydiv.style.backgroundColor = '#fff';
	mydiv.style.color = '#000';
	mydiv.innerHTML = '<a href="javascript:img_fix();">fix</a>';
	document.body.appendChild(mydiv);

},false);

This code is intended (and tested) to run in Opera, but I'm sure it could be adapted to greasemonkey with a minimum of effort. You can modify the replace statement to handle URLs that don't quite fit your description. – 74  23:24, 28 February 2009 (UTC)

You are a fucking hero for doing that for me! Unfortunately I can't seem to get it to work in greasemonkey, but thank you anyway for the time you put into that. While searching I came across this which does exactly what I want but only on coppermine galleries. If it's not too much to ask, could you have a look at that script and see if it could be adapted to my urls? Again, thank you, you deserve another barnstar!

Here is a greasemonkey equivalent script:

// ==UserScript==
// @name           Thumbnail Sourceror
// @namespace      http://userscripts.org/users/useridnumber
// @description    Attempt to replace all thumbnails with linked image content
// @include        *
// 
// ==/UserScript==
(function() {
	for( var i = 0, j = document.getElementsByTagName('a'); j[i]; i++ ) {

		// if an anchor tag links to an image file and contains an image tag, use the link href for the image tag src

		if (j[i].href && j[i].href.match(/[.](bmp|gif|jpe?g|png|svg)/) && j[i].childNodes[0] && j[i].childNodes[0].src) {

			j[i].childNodes[0].src = j[i].href;
		}

		// otherwise, check if an included image tag's src contains "thumb" and replace it with "images"

		else if (j[i].href && j[i].childNodes[0] && j[i].childNodes[0].src && j[i].childNodes[0].src.match(/thumb/)) {

			j[i].childNodes[0].src = j[i].childNodes[0].src.replace(/thumb(nail)?s?/,'images');
		}
	}
 })();

You'll probably want to turn this script off when you're not using it. – 74  19:55, 1 March 2009 (UTC)

Laptop Head to Head

Which one of these laptops is faster in terms of gaming performance and image/video processing?

The 2.4 Ghz MacBook Pro: http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10111222&catid=

Or the HP HDX 16t Premium series upgraded to the same price as the MacPro: http://www.shopping.hp.com/webapp/shopping/computer_series.do?storeName=computer_store&category=notebooks&series_name=HDX16t_series&a1=Category&v1=Performance%20and%20entertainment

Both are roughly around $2,000 CAD.

By looking at the technical specs, I'm assuming that the HP will give better performance right? If so, aside from styling, what does the MacBook Pro offer over the HP to justify its equivalent cost?

Acceptable (talk) 20:04, 28 February 2009 (UTC)

As far as I can tell, portability. Looking up reviews on the Google, the HP might have anywhere between 119 minutes and 156 minutes battery life in 'regular use' (that is, wifi, web browsing, not using the optical drive or doing 3D games); reviewers say the Macbook Pro will do ~300 minutes. The HP is also larger (14.9 x 10.0 x 1.7 inches vs. 0.95 x 14.35 x 9.82 inches) and heavier (7.3 lbs vs. 5.5 lbs). If you don't care about that stuff, that HP and other laptops will no doubt offer more value. -- Consumed Crustacean (talk) 00:23, 1 March 2009 (UTC)

Are the games you want to play available on Mac? Astronaut (talk) 20:26, 1 March 2009 (UTC)

That is relevant as well; you have to factor in the price of Windows if the games aren't on OS X (unless you have access to a copy of Windows, or wish to "acquire" it through other means). Apple also has this tendency to underclock their laptop GPUs to a degree, likely due to heat and/or power usage concerns. This will obviously cause some performance degredation. You can up the clockrate in Windows using tools like Rivatuner, but you risk overheating.

I played with the HP site, got a laptop at about the same equivalent price, but with 4GB of DDR2 RAM (compared to 2GB DDR3 in the MBP), a 320GB 7200rpm HDD (compared to 250GB 5400rpm), a 1920x1080 screen (vs. 1440 x 900), 2.53GHz Core 2 Duo (vs. 2.4GHz), a BD/DVD/CD drive (vs. DVD/CD), and the same 9600M GT GPU (the MBP also has the weaker 9400M which can be switched to in order to improve battery life). There's no doubt that this is better value if battery life and size/weight is of no concern. -- Consumed Crustacean (talk) 23:04, 1 March 2009 (UTC)

Freeware utility: Screenshots with Alpha Transparency

Is there really no freeware utility able to make screenshots of windows with an alpha channel? (Many Windows Vista screenshots on English Wikipedia have alpha transparency preserved.) --Andreas Rejbrand (talk) 20:08, 28 February 2009 (UTC)

Window Clippings is the only one I know of. It's not free any longer, though the old free versions can still be found. -- Consumed Crustacean (talk) 01:51, 1 March 2009 (UTC)

Thank you very much. I had been looking at Window Clippings, but didn't know that there were old freeware versions of it available! Thanks again! --Andreas Rejbrand (talk) 13:04, 1 March 2009 (UTC)

Resolved

OT: I don't get it. Why would one want to make screenshots with alpha, and where would such a thing occur? -- Fullstop (talk)

In Windows Vista, the frame around a window is not 100 % opaque, but slightly transparent. Thus, if you take a screenshot of a window using Windows ordinary "Print Screen" method, you will see what is behind the frame, which usually is not what you want. In addition, the frame is not perfectly rectangular, so even if you position the window in front of a white area on the screen, a few white pixels will be visible in the screenshot, which does not look very good against a black background. Therefore, one would like an application, such as Window Clippings, to copy only the pixels from the window alone, with the alpha channel preseved. See this example of the difference between an ordinary screenshot and one with alpha data preserved. --Andreas Rejbrand (talk) 21:25, 1 March 2009 (UTC)

Now I see that the alpha channel is still lost in the first example, but surely you get the point: if the page background were black, the first screenshot would look much better with its alpha channel. --Andreas Rejbrand (talk) 21:32, 1 March 2009 (UTC)

Also, if you would like to paste the screenshot (of a window) on a (larger) screenshot of a desktop, then, if it is going to look good, the content of the desktop must be slightly visible below the frame of the window. This is only possible to accomplish (reasonably easy) if the alpha transparency data is preserved in the screenshot. —Preceding unsigned comment added by Andreas Rejbrand (talk • contribs) 21:57, 1 March 2009 (UTC)

March 1

change camera drivers

I have a HP Pavillion laptop with an integrated webcam, however I really like Dell's webcam center. I was able to download and install the dell webcam center but the webcam driver isn't supported. Where would I get one that is supported and how would I get thoe drivers to replace the ones currently installed? --omnipotence407 (talk) 00:27, 1 March 2009 (UTC)

Since your webcam is integrated, it is, of course, and HP webcam. An HP webcam can only work with it's own drivers, and it's own software. Software from different vendors, Dell in this case, will not support the webcam in question. The exact same thing applies to the drivers installed for the webcam.

So, in a nutshell, your stuck with HP's webcam software, and essentially the only way to bypass this is to download a freeware webcam application, or switch to a different operating system, such as Ubuntu. Sorry. Until 01:56, 1 March 2009 (UTC)

Manually backing up Hard Drive

I want to back up my Vista and XP machines. Suppose my computers each only have 1 hard drive (let's call it C: in both cases), is it sufficient to just double-click on the hard drive in "My Computer", hit Select All and copy all into my external hard drive? Acceptable (talk) 00:54, 1 March 2009 (UTC)

Um, well this depends on what you want to do... Do you want to just back up all of the files on the backup drive itself, or do you want to make the external drive bootable? Until 01:51, 1 March 2009 (UTC)

If you either want to do the latter or want to make a copy within a backup drive that you can later turn into a bootable disk, I highly recommend Clonezilla. (Alternatively, you may feel reassured by a product coming from a conventional corporation, and want to shell out 70 bucks for Symantec "Norton" Ghost; it won't actually be of any additional help, but maybe we should all do our bit to save large corporations.) Clonezilla will ask you lots of questions that you probably won't be able to answer; just hit Enter for the default choice every time. Well, almost every time: don't become too zonked out by the process, as although the program can "read" your computer it can't read your mind, and a couple of the questions ask you what you want to do (back up, restore? to and from a drive or an image?) and of course you have to get those right. Hoary (talk) 04:08, 1 March 2009 (UTC)

If I'd like to just back them up, bootability is not a necessity, just doing what I described is adequate right? EVERY file from my computers will be copied over? Acceptable (talk) 04:20, 1 March 2009 (UTC)

I've been running a WinXP program called Drive Snapshot (www.drivesnapshot.de) which claims to address the low-level issues in copying a complete operating system. It allows you to back up while doing other work. According to the company, you can restore a complete, runnable system from backup (including the OS), though luckily I've not had to test that. Drive Snapshot saves a 40 gigabyte XP system to an external hard disk in about an hour. (Both Drive Snapshot and Ghost cost some money, order of $70.) I would not be confident that the simple method of a 'Select All' on the C: drive would do what you want. What happens to files that are in use by the OS? Older backup programs would choke on anything that was in use when you tried to copy it. EdJohnston (talk) 05:09, 1 March 2009 (UTC)

Clonezilla will do what you want, and it will do it for no money. However, you won't be able to do any other work while it is at work. (Incidentally, I'm surprised by your desire to copy every file but lack of interest in bootability from the result; why else back up every file?) -- Hoary (talk) 05:36, 1 March 2009 (UTC)

To be a little more specific here: generally speaking, you can't just copy the files of a piece of Windows software to another machine and expect it to work. So, typically, unless you're creating a restorable (and bootable) backup of the entire hard drive, it's not very useful to copy anything except the files that contain your work and other files you use for business or pleasure -- typically, the "My Documents" folder and its equivalents on the computer. The rest of the files tend to be largely useless, because the majority of the software on that hard drive won't be much good without the Windows registry entries they require to work. -- Captain Disdain (talk) 08:51, 1 March 2009 (UTC)

Well put. Though if copyright issues didn't stop me, I'd grab some of the fonts too. Hoary (talk) 10:28, 1 March 2009 (UTC)

Sure, there may be other things. Browser software bookmark files, your mp3 collection, if it's not under My Documents, game saves, that super secret porn stash... stuff like that. But the point still stands. -- Captain Disdain (talk) 12:37, 1 March 2009 (UTC)

If the OS is running at the same time, you will almost certainly encounter locked files. Copying files to a set of DVDs or external drive will stop dead when it encounters a locked file, leaving you with a big manual job trying to decide where it has got to in the copy process. As Captain Disdain suggests, just copying "My Documents" (XP)/"Documents" (Vista) and some other choice bits that you can't replace or recreate easily, is probably the best way (and it's smaller too, so it might go quicker and it might fit on one DVD). Oh, and don't forget to backup your email files either. Astronaut (talk) 20:20, 1 March 2009 (UTC)

If you're doing a backup in case the drive dies, something like Norton Ghost (or some free replacement) works well. You can also try doing a bit-for-bit copy using a *nix utility like dd, which is also very free and very straightforward. Shadowjams (talk) 08:28, 4 March 2009 (UTC)

CSS hover

What CSS elements of divs can be changed with the :hover thingy? I tried to change a bunch of things (see testing page; the ads aren't there by any decision of mine), but all I can see that actually changes is the size of the div. What else can you change? (I'm trying to build a website completely without Java and Javascript; I realize that those would make this easier) flaminglawyer 01:29, 1 March 2009 (UTC)

Technically, you should able able to change any property of the element using any selector. In practice, there are always a few slips for each browser, especially Internet Explorer, but it's mostly for very obscure usage of CSS. There are two problems with your code, though, here marked in bold:

div:hover {background color:gray; border:5p solid blue; color:white; height:20%}

It's background-color, with an hyphen, and "p" is not a valid unit, so it is ignored. Use pt for points. — Kieff | Talk 01:35, 1 March 2009 (UTC)

Oh, sorry, I knew that, just typos... Thanks, my hope in CSS is restored. flaminglawyer 01:45, 1 March 2009 (UTC)

IE is the big difficulty with :hover. It supports it on nothing except anchor (a) tags if I recall. If you are clever about it, you can get a lot of mileage out of the anchor tags, but it is not straightforward and can lead to some somewhat nasty nesting of things. --98.217.14.211 (talk) 14:59, 1 March 2009 (UTC)

Format a disk that refuses?

I'm using WinVistax64 and detected a diskerror when TrueCrypt refused to encrypt my device. CHKDISK comes up with nothing. It won't format with the right-click+format guide, so I tried "format E:" in cmd (as admin), but it came back with something like "You are not allowed to format this volume". I am the only user and admin. I formatted another drive today as well, w/o problems. If you know a solution - great! I have no idea what it could be, since I've never seen anything like this before. Also, as a quick fix, do you guys know any bootable CD's or software that would allow me to format it as NTFS? Thanks in advance! —Preceding unsigned comment added by 81.231.234.120 (talk) 02:00, 1 March 2009 (UTC)

Did you right-click on 'Command Prompt' and select 'Run as Administrator' to open cmd.exe? If not, do that, and then issue the format command.(Nevermind that, I apparently can't read) Also, I'd suggest trying to run a 'chkdsk e: /r /f' before trying a format. It may tell you how much of the drive has gone bad (sector-wise). (Washii) 63.135.50.87 (talk) 07:31, 1 March 2009 (UTC)

Almost any bootable OS CD will allow you to format the drive (not necessarily to NTFS); at which point Windows will most likely jump at the opportunity to format an "unformatted" (read "non-windows-formatted") drive. It'll take a little longer to format it twice, but this way you aren't relying on some reverse-engineered code to NTFS format your drive. – 74  13:20, 1 March 2009 (UTC)

While not impossible it would be rather unlikely. Perhaps windows is merely confused. You could indeed try 76.167.241.45's suggestion below to NTFS format it using Linux. If that doesn't work, you could try formatting it in Linux with some other disk format, then try reformatting it as NTFS in Windows. If that still fails, it's time to replace the drive. – 74  22:21, 1 March 2009 (UTC)

Pretty much any Linux LiveCD will be able to format it as NTFS. You can run "mkntfs" from the command-line, or use graphical programs like QtParted and GParted if available. SystemRescueCD is a good LiveCD which includes GParted and other rescue tools. Knoppix 5 is a good LiveCD which includes QtParted. If you want a more dedicated CD, GParted has a GParted LiveCD. --76.167.241.45 (talk) 21:44, 1 March 2009 (UTC)

Firefox bog

As my link to the past or whatever, I still sometimes use one computer that has Windows (specifically, Win 2k). For a long time I was using Mozilla ver 0.7 or thereabouts on it; this seemed a fine program to me. Then I upgraded to Firefox ver 0.92 or so; this seemed slightly better. Last week, having at long last broadened the band to this computer, I thought that I should kowtow to "virus" hysteria etc via all the "security enhancements" of the latest Firefox. (Also, my beta version of Firefox did have minor annoyances; for example, worldcat.org consistently made it crash. And I even thought I'd read somewhere that newer versions of Firefox ran faster.)

So I upgraded to Firefox 3.0.6 (as of a couple of minutes ago, still the latest). But what a slug this can be! Some days, it's OK. On others, even typing a message such as this is tiresome, as it can't keep up with my typing. When this happens, if I close it down completely (and check in MemTest that none of it lingers) and reopen it, it's often as slow as it was before.

Right now, it's open in a different window. MemTest reports that it's using 56kB of memory; which I don't suppose is excessive. In order to type this, on the selfsame computer I'm right now using Opera 6.03 (yes, your grandfather's Opera; I think it dates from 2002). It's fine; no drag at all. So all in all I don't think the computer has got any malware.

As far as I can remember, I've plugged in no plug-in or extension. (I don't even have Flash.) What stunningly obvious factor might I have overlooked here? -- Hoary (talk) 03:38, 1 March 2009 (UTC)

What kind of websites are we talking about? Do you have anything open (even in another tab) that's super-AJAXy (like Gmail or Google Reader)? They can sometimes really bog firefox down on low-performance computers (I've frequently noted that on my Eee PC running Ubuntu, Google Reader will spike to 100% CPU usage after using it for a while, bogging the whole browser down). Or does this happen if you only have relatively light-weight pages open (like Wikipedia articles).

One thing you should definitely do is to start monitoring your processes. Install Process Explorer and have it running in the background, it'll give you a little graph of CPU usage in the system tray. You'll start to notice what behaviors that bring the browser to a creeping halt (or if it even is the browser at all. it's possible that it's some other program messing with you). BTW, when you said it takes up 56 kb of memory, you really meant that it takes up 56 mb of memory, right? Because at no point in the history of any universe has firefox taken up that small amount of memory.

I would recommend you install Google Chrome (as it is known in all the lands for it's amazing swiftness), but I don't know if it works on Win 2K. Probably doesn't.

My best guess is that your computer is simply old (btw, what specs do you have?) Software from 2002 is obviously going to be running faster, because it assumes that the hardware it's on is also from around 2002. Your computer may simply be too slow for the latest version of Firefox. If that's the case, there's no shame in just using the version of Opera you have that works (but for God's sake, don't use IE 6!) Belisarius (talk) 09:00, 1 March 2009 (UTC)

Thank you, peoples. Er, yes, not 56kB, I meant 56MB. I don't remember the specs of the computer or even how to look them up; of course it's primitive by 2008 standards and it has 192MB of RAM. It's a curiously durable laptop, and since its screen is tolerable even by today's standards and its keyboard is far better than any other I remember trying (not that my experience here is wide), I'm in no rush to get rid of it. (When it does eventually conk out, I plan to replace it with something running Debian.)

No Gmail, no Google Reader.

However ancient the computer is, it's easily good enough to run Firefox ver. 0.9.2 or whatever that was. And no offense to the hundreds of people who've together put thousands of hours into improving Firefox since then, but I see little change to the program beyond increased stability (good!), increased prettiness, and even more desperate attempts at URL completion; there's no obvious reason why it should be slower.

The sluggishness is very localized. I'm using Firefox now, and as I type this autoreferring sentence, it's fine. But when I go to type in the "Edit summary" box of this very same page, I type ahead of what I see -- which doesn't matter, but it's disconcerting (and I'd certainly never experience it in the beta).

I know that WP isn't a RS, but for what they're worth its articles say that neither Chrome nor Safari runs on Win2k. Perhaps K-Meleon, said to be slimmer than Firefox, is for me. Or, after I've treble-checked that it won't zap ver. 6.03, perhaps a recent Opera would be the thing. -- Hoary (talk) 10:21, 1 March 2009 (UTC)

You might try disabling javascript and see if the performance improves; I've seen any number of sites that bring my browser to a crawl with poorly-formed javascript. Beyond that, there are a number of features that theoretically could be the source of the slowdown, many of which are controllable using about:config. You could go down the list disabling everything you don't need and see if the base performance improves. That being said, it is certainly possible to install and run multiple copies of Opera (just make sure to choose a new install directory). – 74  12:33, 1 March 2009 (UTC)

Restoring deleted files

I have an old Windows 2000 laptop that I recently dug up. It was reformatted about 5 years ago and I haven't used it since. Is there anyway I can retrieve/restore these reformatted files?

If it was a partition issue on top of the formatting, try gparted. It does really well at reconstructing destroyed partitions. If NTFS was reformatted over it in the same spot, I think you'd lose the NTFS tables (since it would put them at the same places) (although could be wrong), and so you'd need to do the more labor intensive file-carving. There are a few good file carving utilities out there, so start looking at that route. Shadowjams (talk) 08:25, 4 March 2009 (UTC)

250W PSU and a new Video Card

Hi all. I was wondering if you could recommend any half decent video cards that would work with a 250 watt PSU. I have a HP A6632F with 4GB RAM, 2.4GHz E220 DuoCore processor, and Vista Home Premium. This computer uses PCIE 2.0 x16. I used to have a ATI Radeon 9800XT for my old HP (200W PSU), and I liked it quite a bit. I'm hoping for something a bit better than that, but an equivalent would be okay, I guess. I'm not sure what else in the way of information I should provide, so feel free to ask. Thanks in advance, --AtTheAbyss (talk) 04:52, 1 March 2009 (UTC)

I see that nobody has recommended such a graphics card yet, and I won't either. You've got a pretty good machine, I wouldn't recommend spending money on a bottleneck-esque video card. I'd recommend the 8800GT as good bang-for-the-buck, but you'll need a PSU with at least 400 watts. But if you're going to purchase a new PSU, perhaps future-proof it a bit and get some more wattage. Useight (talk) 20:18, 1 March 2009 (UTC)

I agree - given the amount you're going to spend on a graphics card - it only makes sense to buy a decent power supply and not let such a trivial thing limit your choices. 250 watts is hopelessly inadequate these days. Even if you find a card that'll work - it'll be slow and nasty - and the power supply will run hotter and fail sooner. Then you'll end up paying for a new power supply - and still be stuck with an unnecessarily slow and nasty graphics card. Better to upgrade the power now and have a free choice of which card you can use. Then you can look for the best deal without being limited to a small range of cards. SteveBaker (talk) 03:36, 2 March 2009 (UTC)

Hmmm. The way the economy is I'm not sure I'll be able to afford a new PSU as well as a new graphics card anytime in the near future, although you both make valid points. The reason I brought up my ATI Radeon 9800XT is because I was able to play battlefield 2 and call of duty 2 (both released in 06) even though the card came out in 03. I was hoping I could find an older card with that kind of staying power. I plan on going into the military soon, so I don't need something that can play games released last year, this year, or next year. I'm just looking for something that can play BF2 and CoD2.--AtTheAbyss (talk) 04:25, 2 March 2009 (UTC)

Konqueror, Firefox and openSUSE

Earlier I was updating the Kenn Borek Air article. This involved going to Transport Canada's database and searching for the aircraft registered to Kenn Borek, which gave me a list of 38, with 15 to a page. In Firefox I seem to be stuck on page 1, clicking on the links for page 2 or 3 just reloads page 1. If I use Konqueror I can look at each page but the "common name", "serial number" and "owner regist. since" fields are all blank, with that information on two lines just below the "return to search" and above the "38 matches found" and looks like "Beech B 42 1992-12-03 Dehavilland 311 2000-10-11 Beech BB 7 1992-09-17..." Any ideas why that is happening and how to solve it. By the way it's not a problem with Firefox in Windows. I was able to work around it by clicking on "printable version", so it's not a major problem but it is annoying. Enter CambridgeBayWeather, waits for audience applause, not a sausage 08:21, 1 March 2009 (UTC)

The page is using IE-specific javascript. Specifically, it is manipulating an object named 'frmsubmit' (e.g. frmsubmit.action), where "frmsubmit" is the name= of a <form>. Both js and css (which was evidently an afterthought) is quite amateur.

When this happens - it's very important that as many people as possible complain to the webmaster at the site.

MoWeS to Real Server

I have installed MediaWiki onto my flash drive (as a wiki on a stick), as part of MoWeS. That was recommended to me here That includes Apache, PHP and MySQL. Now I am wondering how I would go about turning that into an actual website. I know I need to buy a domain name, like at GoDaddy. What else would I do? Thanks, 99.224.117.66 (talk) 20:53, 1 March 2009 (UTC)

You'll need to explain more about what you really want. If you want your MediaWiki install to be used by people over the internet (and not just inside your school or office) then you 're really best to get a web hosting package and install MediaWiki etc. there. While you could host it on a regular home machine, you'd need to use Dynamic DNS or get your ISP to give you a static IP address - and even in that case, I don't know why you'd want to have the software on a USB stick. I'd have thought the only reason you'd install someotng on MoWeS is for purely personal use, with you the only person accessing it. 87.113.100.227 (talk) 21:17, 1 March 2009 (UTC)

SOrry, I should have said that I want to move it off the flash stick. I would like for it to be available over the Internet, to anyone. I had heard about Dynamic DNS, but wasn't sure. I am pretty sure I have a static IP address, as I have the same one now as I did in the previous post (is that correct?). I would use my home machine only to save the costs of using a web-hosting service. Thanks, Genius101^Guestbook 21:42, 1 March 2009 (UTC)

You can get some very cheap hosting solutions, from people like DreamHost and GoDaddy; remember that hosting it from your desktop machine means that a) that machine has to be on all the time (24/7/365) burning your electricity and warming your home. And if that machine needs to reboot for software updates, or because it's crashed, or runs slow because you're playing GTA5 on it, then the web service suffers. Worse, that A in ADSL stands for asymmetric - your upstream is much much slower than your downstream, which means that only a few visitors to your site can exhaust your upstream bandwidth and make your site very unresponsive. Hosting centres, by contrast, have high-bandwidth symmetric connections, so they're not handicapped in this way. Now all of this is fine if you're the only user of it (like you're just connecting home when you're elsewhere) but if other people are going to use it they're going to be disappointed in anything that's hosted in your home. If you really still want to host at home, then you'll need a guaranteed static IP address (you rarely get that without asking for it explicitly, and paying extra) or a dyndns (or the like). Then you buy a domain and have your hosting company set their name servers to point to your static IP. Then someone can access your machine at home as easily as if they were in the next room - including all the ports you left open and the services you didn't disable (which makes security a real headache). 87.113.100.227 (talk) 22:12, 1 March 2009 (UTC)

After reading that, I think that I probably will end up going with the paid hosting services. It's just a lot easier. Thanks a lot for your help! Genius101^Guestbook 22:45, 1 March 2009 (UTC)

As for transferring it, if both your stick and the server are using MySQL, you can use a tool like phpMyAdmin to transfer the whole database in one big step. I don't know what other complexities are entailed in a MediaWiki data transfer, though. (Also, paid hosting is pretty cheap, on the whole, and worth it.) --98.217.14.211 (talk) 00:02, 4 March 2009 (UTC)

What is the best web browswer for Windows?

I've been trying to figure it out for a while now. IE 8 looks promising, and it may be even more secure than the other browsers. Opera has always been an underdog favorite of mine with lots of innovative features. Firefox is thrusted towards the top because of its ability for extensions and add-ons. I've never liked Safari, but Safari 4 seems and sounds to be really good. What do you guys think is the best web browser for Windows? —Preceding unsigned comment added by 71.117.46.229 (talk) 21:02, 1 March 2009 (UTC)

Of the browsers you name, IE has been (for years now) the slowest, buggiest, least standards-compliant, and overwhelmingly least secure browser. Alleged improvements have always been in the next version, whatever than version will be, but it's consistently failed to catch up. Of the others, Firefox has the advantage of lots of extensions, Opera tends to be a bit faster and a bit further up the standards curve. Safari is perfectly good, as is its cousin Google Chrome. Beyond that it's a matter of taste; there isn't a "best" out of Opera/FF/Safari/Chrome. 87.113.100.227 (talk) 21:13, 1 March 2009 (UTC)

I disagree with that. IE7 is loads better then Safari and to a lesser extent Chrome in most regards even though it's a lot older. And there are a lot of people who share my view, Apple products on Windows are often lambasted. I'm not even convinced Safari is more secure [1] [2] beyond the fact no one targets it due to the tiny market share. Nil Einne (talk) 05:30, 4 March 2009 (UTC)

None of these programs costs any money. Unlike operating systems or indeed plenty of free-as-in-speech-or-beer programs (such as R) for very different uses, getting acquainted with them requires a trivial amount of time of time and effort. Therefore experimentation is free in all senses. Further, it's obvious that what people prefer will depend on their own, well, preferences (notably, on what they're already used to). So why ask? --

I think it's all a matter of opinion - there are features in each that others lack - some people need JavaScripting speed - others need cross-platform compatibility - others want loads of plugins...who knows what else? But if you have a Windows PC, you can download pretty much all of them for free - they don't interfere with each other - you can have all of them installed at once. Play - enjoy - pick your favorite. Mine happens to be FireFox - but your mileage may vary. SteveBaker (talk) 03:11, 2 March 2009 (UTC)

I personally prefer FireFox with IE7 a close second. My main gripe with IE is the way it handles content you've typed in (like this) that is it doesn't save it very well so if you visit another website and come back, it's liable to be gone (very annoying when I compose a long response and lose it). I've briefly used Chrome but didn't find that appealing (the individual process was interesting but it had numerous other issues but that was a beta). Safari is of course even worse from my brief experience (to be honest, I don't know of any Apple product on Windows that is worth jack shit). Haven't used Opera in a long while. Security wise, I trust Firefox much more then IE, not necessarily because FireFox is a load better but because it's still targeted a lot less. Safari, and all Apple products like to try and force junk down your throat and keep constantly running crap on your computer (updaters and other bullshit). Chrome and Google products are heading in that direction but thankfully are not as bad as Apple yet. FireFox and IE are a lot better (unless you count the stuff that already comes with Windows, but even that little of it is specific to IE nowadays) Nil Einne (talk) 05:25, 4 March 2009 (UTC)

I personally use Firefox, Flock, Chrome, Opera, Maxthon, and Safari, in that order of preference, all for different reasons. I wouldn't touch IE with a shitty stick and I get rid of every application that tries to open it in favour of my other preferred browsers.

Looking for something that says "Ready" when startup finally finished, and requires entering a key code to allow computer use

I have Win XP, set to autologin (*). After startup has technically finished, the resident antivirus scanner and ccleaner keep the computer busy for a few minutes more. During this time the computer is very slow - I prefer not to use it. Is there something I could install that would show a sign on the desktop indicating the computer was now ready to use, all scanning and cleaning done? I imagine it would be put in one of the startup folders. I would also like it to stop anyone using the computer until I enter a secret key of some kind. ((*) Note - you might be thinking of suggesting that I no longer use autologin, and use the password login option instead. But this would be much slower and much more inconvenient as I would have to return to the computer twice - once to switch it on, then wait a long time, then return the second time to enter the login password, and then wait several more minutes for stuff to finish. ) 89.241.154.51 (talk) 21:26, 1 March 2009 (UTC)

Sorry, I don't know. But have you considered Linux? No tiresome "antivirus scanning" necessary, and startup not only is fast but also can be made to be "verbose", so you get impressive-looking screenfuls of inscrutable technical stuff whizzing past during the short period while you wait.

Many people want to play DVDs on their computers; ergo, computers are made for playing DVDs. They'll all do what most people want them to do. (If you have particular requirements on top of these, feel free to state them.)

Let's think dark thoughts for a moment. My office bought three computers just 11 months ago and last month the hard drive of one of the three died. That instantly rendered the computer less desirable than its crappiest competitor. Sure we got a new replacement drive under warranty, but we weren't compensated for the time we then lost in reinstalling a pile of software because we'd been too stupid to make a disk image. So one "feature" I'd look for is the combination of a Clonezilla CD (free) and a large external hard drive (cheap), in order to back up whatever's on whichever computer you buy. Luckily you can do this for any computer. Budget for it.

Vista Wireless Connections

Let me begin by explaining that am a network administrator and programmer, but I have not used Windows since Windows 3.0. At home, I have a wireless router. It is secured and does not broadcast. My wife's new laptop has Windows Vista. Everything was great before we recently moved. She turned on her computer and it connected automatically using the built-in wireless connection. Now, we live in an apartment complex. When she turns on her computer, Vista automatically sees 20-30 unsecured wireless connections. It gets confused and refuses to connect to my router unless I create a new connection and type in the entire cryptic security key - EVERY TIME. Is it possible to get Vista to use one and only one wireless connection? Is it possible to tell Vista to completely ignore specific wireless networks? All I want is to have my wife's computer connect to my router when it turns on without any trouble at all, exactly as my Redhat laptop does. 64.251.148.141 (talk) 03:25, 2 March 2009 (UTC)

Not broadcasting the SSID is pretty much completely pointless, and as you can see in this case, creates a lot more trouble. I know that some wireless connection management utilities do have the ability to do let you manually create a "profile" for your network that doesn't broadcast SSID, and set that profile as the highest priority or something. I am not sure if Windows Vista's built-in wireless network manager has this ability. --206.72.77.76 (talk) 03:47, 2 March 2009 (UTC)

My own server at home - WWW/FTP/DNS? - possible?

Hello, Refdeskers. I'm getting closer and closer to setting up my own server at home. I know it will be very convenient, and I know it's useful and possible. I am prepared to dedicate a separate line/IP for it, and I am prepared to spend a lot of time setting it up. The server would ideally be a small and quiet standalone box sitting in the corner, with its own connection to the world, and LANned to my workstation to transfer files to and fro. Now, I know that the basic functionality I need, as listed below, is doable without sweat, but just to make sure I am listing the things I'd need it to do:

1. work as an FTP server to be able to host larger amounts of data easily
2. work as a WWW server to host my websites easily
3. work as a DNS server to keep my domain names on (I'm not that great with DNSs and domain names but I have two that I'd like to keep and use).
4. being able to use it to do my e-mail would be grand but if I manage the above three I'll already be very happy.

So, I know about Apache and that it's easy to install and I more or less know that this doesn't have to be a state of the art machine - my knowledge suggests to me that a Pentium II with a 20 gig hard drive and an ordinary monitor will do.

My questions, basically, are these:

1. Is setting this up really that easy, or are there any hoops that you have to jump through?
2. Is getting the functionality as listed above so straightforward?
3. Is it in effect possible to set up a server with functionality as described above, while at the same time using this computer as your workstation? It may be pointless because the machine would have to be more powerful, but I just want to know.

Brainstorming is welcome. To clarify, I have mastered the basics of Linux and am pretty knowledgeable with computers otherwise too. If there are guides out there or books I just need to buy and read, you can point me to them. Thanks in advance and cheers! --Ouro (blah blah) 13:40, 2 March 2009 (UTC)

If you plan on having other people visit it, see the discussion at #MoWeS to Real Server, above. Mimetic Polyalloy (talk) 13:50, 2 March 2009 (UTC)

Yeah, I am planning to allow other people to visit my sites. Thankfully those don't require much in terms of bandwidth. And as for FTP speeds, even if they aren't that great, the slow speed will be offset in my eyes by the ease of storage. --Ouro (blah blah) 14:18, 2 March 2009 (UTC)

There are a ton of excellent books out there on this sort of thing, but I usually use online documentation. For FTP, there are a lot of server programs around, and they usually aren't too hard to set up. There's probably one configuration file for you to edit. Apache can be simple to set up, especially if you use a web interface like Webmin to configure everything, but it can also be a huge hassle if you're trying to do something complicated. BIND (for DNS) can also be very difficult to configure properly. The best thing I can suggest is to check out the Linux Documentation Project, which has HOWTOs on all of these subjects. Some are a bit old, but even then they usually still work. Also, look for documentation on the website of your distribution (Ubuntu, Fedora, Debian, SUSE, whatever) - they usually also have guides and tutorials that'll walk you through the steps. And to answer your last question, yes, it's very possible to use a server as a workstation. The power of the machine isn't really as much of an issue as the fact that if you mess anything up while browsing the web or gaming or whatever on your workstation, it'll take down your server until you fix the problem. As a result, most people like to keep them separate. Anyway, good luck! Indeterminate (talk) 21:41, 2 March 2009 (UTC)

I'll answer from the end to the beginning: That's one reason to keep those two machines separate. Another one is to set up the server to not be as power-hungry as your usual workstation machine. As for the documentation, I'll have a further look in the documentation when I have a little time. I am already looking forward to setting this machine up. Thanks, Indeterminate! --Ouro (blah blah) 06:53, 3 March 2009 (UTC)

You may be using "FTP" terminology loosely, but I highly recommend setting up SFTP rather than FTP. It is not any more difficult to set up or use, but it will prevent unauthorized data interceptions. Consider reading up on SSL, HTTPS, and other secure protocols as well (in my experience, HTTPS is a bit more complicated to set up, but tutorial/walkthroughs are plentiful). Is security important? It depends on many factors; in some sense, nobody will specifically target your machine, and if you have nothing sensitive on it, the "who cares" mentality may work for you. I don't run a "high-profile" website, but access logs on my personal-use system (open to the internet at large) regularly show more than 100 phishy ssh-login-attempts per minute (from spambots, presumably - with fictional login names from anonymous random source IPs...) - the internet's a scary place! Using naive protocols only helps spambots and network scanners. Standard secure alternatives are a simple, effective way to keep your system safe. Nimur (talk) 07:27, 3 March 2009 (UTC)

Speaking of using terminology loosely, Nimur, check out that SFTP link. At least 3 protocols are commonly called SFTP. :) SCP (or file transfer with SSH) is great, but it's a little awkward with Windows. FTPS (never heard it called that before) is FTP with SSL, which works well, but I'm not sure whether it has a lot of client support. I think it does. And FTP over SSH would probably work fine, but it just seems silly to me. If you're going to all that trouble, might as well use SCP. Anyway, they're all more secure than FTP, so if you'll be sharing sensitive data, they would be a better choice. Indeterminate (talk) 08:36, 3 March 2009 (UTC)

I know, I know... What I call "sftp" is actually FTP over SSH, because that is what installs with the openssh server on Ubuntu. Your distributions may vary... my "sftp server" is tightly integrated into sshd. FTP has a long and awful history of non-standardization. As you say, SCP is really a better replacement... Nimur (talk) 17:40, 3 March 2009 (UTC)

Heh, well, I call it SCP, but I'm talking about the same "ftp" functionality that's built-in to openssh. That's what I use most of the time, too. I don't think it actually uses that old FTP protocol, but fortunately most FTP clients have good support for it. "FTP over SSH" is different, it isn't built-in to openssh, exactly... it uses SSH tunneling to encrypt the traffic to/from a regular old FTP server. Anyway, the terminology is really confusing, which I guess is the point we're making here. :) Indeterminate (talk) 21:47, 3 March 2009 (UTC)

I'd mostly be planning on hosting my one professional website, which amounts to my curriculum vitae and references, and my hobby website with my photographs. I wouldn't call those really sensitive, but still I wouldn't want any given person to be able to write what they want to my server. As for hosting data (let's call this xFTP, you know what I mean in general), it's mostly going to be things I want to send to other people that are larger than average, which most of the time will mean any photos in bulk from parties or events that I go to with friends. This is the extent of functionality that I'd like my server to take over, and I'd be satisfied if I get this done - this would relieve me of burdens of having to store my data as mentioned above on external services.

It would seem as though it's all simple enough to set up and manage. That's good. Cheers, Ouro (blah blah) 10:19, 3 March 2009 (UTC)

I do this exact same thing. (See www.teraknor.net) That is hosted off my home cable modem and I run my mail server on there (with which I use IMAP over SSL), as well as ftp services so I can get to my files from anywhere as well as using this for hosting images as I post quite regularly on some forums and occasionally you want to put a picture up. I also host my own DNS records from there and there is one gotcha with doing that, whenever your IP changes you must update the nameserver record for your domain, and that usually takes ~24hrs or so to actually update. I also have a DynDNS setup so I can get back to my stuff in the case my IP has changed and I need to get back into one of my machines. If you can get a static IP for it then you wouldn't have that issue, which would be very nice. 204.16.236.254 (talk) 00:36, 5 March 2009 (UTC)

I had installed few games like FIFA and a flight simulator somehow the FIFA was very slow hence i had to uninstall from my laptop and i also removed all the instances from the "REGEDIT" aswell.

Machine translation of flash websites?

And to a lesser extent, of pdf files.

Any way of extracting the text from a flash website? etc.. ThanksFengRail (talk) 15:12, 2 March 2009 (UTC)

I suspect you'd need to take a screen shot, then feed it into some OCR software, then feed the results into a translator. StuRat (talk) 16:16, 2 March 2009 (UTC)

You can translate pdf files if they're not encrypted, but I think you'll need to use libraries from Adobe or PDFTron (you can see the text if you open a pdf file with visual or notepad++, but there's so much meta-info I think just changing this text will break the file). Or is there a free alternative? As for flash files, Google can parse them, so it's obviously possible. yandman 16:24, 2 March 2009 (UTC)

There is a selection tool in PDF viewer that will allow you to select (actual) text and copy it to another document. Note that this will *not* work on images of text, such as scanned documents. – 74  16:53, 2 March 2009 (UTC)

xp installation issues

Hi! So I decided yesterday to reinstall XP on one of my machines, but it keeps crashing during the install. Thus far, it seems to crash at different points. Every attempt but one has been in the "installing windows" stage, with one stalling at "finalizing windows". Any thoughts? DaRkAgE7_[Talk] 18:34, 2 March 2009 (UTC)

First assumption - bad harddrive. Second assumption - bad memory. After swapping those two out, see if it works. If not, third assumption - bad power supply. -- kainaw™ 18:39, 2 March 2009 (UTC)

Define "crashing". If the system is restarting semi-randomly it could be an overheating problem. If it's blue-screening, then one of Kainaw's suggestions is the most likely source. If it's hanging then it could be a number of different things (including Kainaw's suggestions). – 74  19:47, 2 March 2009 (UTC)

OS X DNS/DHCP settings forgotten

It seems that my OSX computer (10.5.4) keeps forgetting the IP for the DNS server and the wireless router in my home network and resets itself to some wrong ones (in the 192.168.x.x range, however). Manually changing the settings and restoring the right IPs seems to help only for a short while. The Airport seems to work fine (ie. no hardware issues), it pings the correct IPs and it even finds all neighbours' networks (I won't connect, of course!). Firewall is not enabled. What could be wrong? --79.129.171.175 (talk) 20:58, 2 March 2009 (UTC)

Well, if you haven't changed anything, then it should be picking up its DNS and gateway settings (along with its IP address) from a DHCP server on your network (presumably the Airport router). I would check the configuration on the Airport; if that looks okay, check your Wireless settings in OSX - you might be able to manually set them to the correct values; if that doesn't work, hmm. It could possibly be somebody leeching off your wireless who's running a rogue DHCP server, but this is very unlikely. I think it would be more likely that you missed a problem earlier 2 or 3 times in a row. Finally, if this is a laptop, try taking it to a different wireless network to see if the problem follows the computer or the Airport. That'll at least help narrow the problem down.

stock website

Is there a free website where I can type in the price of a stock issue and it will tell me the last time the stock was at that price? Example: When was the last time CAT was $20 a share? 65.167.146.130 (talk) 21:01, 2 March 2009 (UTC)

UpDown or Wikinvest (and pretty much any other stock-related websites) have a stock history in chart form, so you could just set the time to 5 years or something long like that and figure it out for yourself. In your example (CAT at $20), the last time was October 11, 2002, when its price was $18.29. The next day it jumped to $20.50, and it's never been back below $20 again (although it's getting pretty close nowadays). flaminglawyer 03:24, 3 March 2009 (UTC)

Capabilities of netbooks

I need a new computer, but I don't want to spend more than a few hundred dollars on it. I recently thought about getting a netbook, but I don't know very much about them, so I have a few questions before I run out and buy one. First, what sort of capabilities do they have? I know they don't have CD drives (which isn't really an issue for me), but how are they for hard drive space and memory? Are they as customizable (in reference to graphics cards, etc.) as an ordinary desktop/laptop? I play a few video games, nothing too extensive (lately I've been playing Portal and the Half Life series), so would I be able to modify a netbook to run those smoothly? Could I even do it with a basic netbook? Like I said, I don't know very much about them or their capabilities, so I'm looking for some advice here. Any ideas (or even a suggestion of a different computer that's still cheap) would be greatly appreciated! --Alinnisawest,^{Dalek Empress} (extermination requests here) 21:14, 2 March 2009 (UTC)

Um... no, you almost certainly couldn't play any recent games on them. Netbooks are great if you want something super-portable that doesn't need to do more than browse the web and check your email, but their processing power is about what desktops probably were 5 years ago. You can't really customize them, either. They are cheap, though: you can get a new Dell Mini 9 for less than $200: [3]

If you want to play games, I'd recommend a cheap desktop. If you already have a monitor/keyboard/mouse, you can usually get just the tower for pretty cheap, less than $500 probably. Indeterminate (talk) 21:31, 2 March 2009 (UTC)

Rats, I figured that'd be how it'd turn out, but I was hopeful... well, I guess I'll have to look into desktops, then. Anyone have any suggestions of cheap ones? --Alinnisawest,^{Dalek Empress} (extermination requests here) 21:38, 2 March 2009 (UTC)

Depending how PC literate you are, you could try to build one yourself. I actually think it's really fun and it ends up being the cheapest way to get a computer with exactly the components you want and need vs buying a prebuilt "closest match" computer. However if you do not have the time or inclination, get your local weekly computer classifieds which should lead you to reputable local computer stores who often have great bargains on inhouse built computers. They are also usually quite happy to configure it exactly to your liking only charging a relatively modest assembly fee. Vespine (talk) 23:54, 2 March 2009 (UTC)

Speaking of capabilities of netbooks: I just bought a Lenovo S10e (slightly modified S10). Although its graphics capabilities are miserable, and I won't be playing any 3D games, my mind was blown away by the capabilities of this little 2-watt Intel Atom. I have been working on some computational research, and two-threaded 2D full-wave FDTD propagation simulation clocks in as fast as my 2.26 GHz Pentium 4 (and sometimes faster!)

Are you not able to access your files, or are you saying you can access your files but not in the usual way? I take it this is a school computer? They often have restricted access which might prevent accessing USB drives, so they only way to see the drive and files in by other means. If you're able to download stuff, try and download and install 7-zip (this is the portable version so doesn't require any administrative rights to install) which can act as a file manager and will sometimes be able to bypass restrictions set on Windows Explorer (My Computer) folders and drives. Then navigate to your thumb drive and see if you can access the files. Also it's good to know keyboard shortcuts for when right clicking is disabled. —Preceding unsigned comment added by 82.43.88.87 (talk) 21:58, 2 March 2009

IE 6.0: don't want to get forwarded to Dell

Whenever my old Internet Explorer version doesn't find a link target, it redirects/forwards to some annoying Dell-sponsored website. It's worst when it's not even about the main URL that I'm trying to open, but just some useless ad. For example, when I'm trying to open Merriam-Webster, I'm getting forwarded to this website: http://www.google.com/hws/dell-usuk-rel/afe?hl=en&channel=us&s=http://ad.turn.com/server/ads.htm?&pub=3817658&code=3817716&cch=3817687&lw=500&lh=20&l=0x0&tmz=5&area=-1&rnd=0.21679996499640325&lmd=1236041915&url=http%3A%2F%2Fwww.merriam-webster.com%2Fdictionary%2Fbla&ref=

Any way I can convince IE to never redirect/forward to that Dell website again?

I'm probably using IE 6.0 (the "number" is much longer and continues with strings etc.), and run it under Windows XP on a Dell computer. The problem has gotten much worse since I've started using a hosts file to block ads (works beautifully in Firefox and Opera, but not in this old IE version)... anyways, there *must* be a way to switch off the auto-forwarding?

It's to do with Dell branding of their PCs and all the crapware that comes with a new Dell. They have modified the error redirector to take you to their website.

NTLM vs LDAP

What is the difference between NTLM and LDAP? I tried going through the Wikipedia article on NTLM, but could not find any information. 203.158.89.10 (talk) 04:58, 3 March 2009 (UTC)

You can't really compare them directly. NTLM is an aging Windows authentication protocol. It's still used in situations where security isn't terribly important for Windows computers. If you're going to compare it with anything, compare it with Kerberos (protocol). LDAP is a specification for a Directory service; almost all directory services are either based on LDAP or compatible with it to some degree. Directory services just provide searchable directories of users, computers, groups, equipment, etc. They can be configured to provide some sort of authentication scheme (like NTLM, Kerberos, or SASL) to verify the identity of users in the directory database. The Microsoft directory service is Active Directory. Apple's directory service is Open Directory, and the most well-known Open Source directory service is OpenLDAP.

But if you simply MUST compare them, LDAP is used in Windows domain environments, while NTLM (mostly) is not. Indeterminate (talk) 08:55, 3 March 2009 (UTC)

PSX Emulator--Issues with Disc Spinning

Hi yet again...

I am using the most recent PSX emulator with a LEGALLY ACQUIRED BIOS. It worked fine for a while, but now my DVD drive seems to stop spinning randomly as i am playing a game (it causes a lot of bad things to happen). I have tried to use a variety of tools to force the drive to keep spinning, to no avail. And, to top it all off, yesterday Windows threw this error at me:

Data Error (Cyclic Redundancy Check)

How can i stop this message and how can i keep the drive spinning at top speed? Thanks.  Buffered Input Output 13:56, 3 March 2009 (UTC)

Those kind of CRC errors usually mean that the DVD drive itself is failing; in a sense, it means that the drive read data from the drive that didn't match what it expected to be there. If it shows up a lot, it's a hardware problem. If you have a spare DVD drive, see if that fixes the problem. Indeterminate (talk) 21:41, 3 March 2009 (UTC)

I believe it could also be a scratched disc. – 74  23:11, 3 March 2009 (UTC)

The disc isn't scratched, and the DVD drive works fine with everything else but PSone disks. Maybe i should mention this too: ALL other discs, including PS2 and other types, work fine, but PSone discs throw CRC errors after reading *.STR files.  Buffered Input Output 13:46, 4 March 2009 (UTC)

That sounds like some form of copy protection/DRM. It is possible that many PS1 discs contain an intentional "error" that playstation hardware either corrects or ignores. You might be able to get a DVD drive to do the same, but it's probably a non-trivial modification. – 74  15:48, 4 March 2009 (UTC)

Standalone virus cleaner

I've been contacted by my system admin and told to take my computer off of the network because they've detected it sending out spam messages (how does it do this? surely not through my gmail accound). I have taken it offline by removing the ethernet cable from the back, and then rebooted into linux. Is there anyway to clean my computer without it being online? I have access to the internet in linux or from another machine so I could download a program to a usb drive. Is there a way to download a cleaning program to a usb drive and have it sanitize my system? Thanks Man It's So Loud In Here (talk) 19:56, 3 March 2009 (UTC)

In answer to your tangential question "how does it do this? surely not through my gmail accound": no, it won't do that. Spambots have their own SMTP transfer agent built in, which they use to pretend (to other SMTP agents) that they're (e.g.) mail.whatever.com Now some malware will attempt to harvest your address book from Outlook or the like, and use that for forged "From:" fields, but hijacking your email client wholesale, or harvesting login info for a web-based email service, is more bother than they need to do. 87.113.86.209 (talk) 21:01, 3 March 2009 (UTC)

In answer to your virus question, you can download the installer for a free antivirus like AVG using the linux box, copy the installer to the USB stick, put the USB stick in the stricken windows box, and run the installer from there. I think the free version will run without an internet connection (that is, it doesn't insist on validating its licence) and while you might be a week or two behind on the latest virus signatures and patches, you'll almost certainly be able to remove the malware. If AVG doesn't find anything, use Spybot - Search & Destroy to scan for more malware. 87.113.86.209 (talk) 21:01, 3 March 2009 (UTC)

This is a little tougher than the old days, when you could just pop in your Thunderbyte, Norton, McAfee 3 /12" floppy and clean up a computer. You may want to have a look at Portable applications. I've found AVG can be problematic after version 7.0 due to registry entries it expects to find (same with Spybot 1.4 and above - although not as bad). Dr. Web claims to have a Live CD that can help, and PC Tools AV is supposed to "run from thumb". The biggest problem, is the rapid changes in the AV world - new strains, morphs, etc. at an hourly rate. Coupled with a more complex file system (NTFS), it can often be tough to find a quick fix. I'd probably buy my system admin a cup of coffee, and ask him what he (or she) recommends. Sorry it took so long to reply, but I wanted to double-check a few things first. — Ched ~ ^(yes?) 17:17, 4 March 2009 (UTC)

Thanks for the replies, I tried AVG from a thumb but had no results. First off, this virus was nast in that windows explorer wouldn't even load unless there was an internet connection. The only way I could get a gui to load was to do it in safe mode. So I installed avg while in safe mode, but then it wouldn't run. I'm not sure if it was the reason mentioned above or not. So I just backed up my data and reinstalled windows. I am not sure what to do now, as I want protection but every AV I've used in the past slowed down my system.

Drive overclocking

My question is as follows: is it possible to override a locked system setup and overclock a drive? If so, is there a program i can use, or a file i can edit, ect. —Preceding unsigned comment added by 99.7.3.15 (talk) 03:50, 4 March 2009 (UTC)

I'm not really sure what you're asking. Overclocking usually means increasing the frequency of CPUs or GPUs (or memory, etc). It doesn't apply to disk drives. You can sometimes increase the performance of a drive by adjusting some parameters in the OS (see hdparm), but AFAIK it's not realistically possible to increase the physical operating speed of a hard drive (its RPMs, for instance). Did that answer your question? Indeterminate (talk) 22:32, 4 March 2009 (UTC)

How long would an unprotected PC last on the net without any kind of protection at all before it was infected with a virus BigDunc^Talk 19:58, 4 March 2009 (UTC)

Well, that would depend entirely on what sites you visited. Tracking cookie - 2 clicks, virus/malware- (depending on which sites), maybe an hour or so.

C++

What is the point of having all of the different things in C++? There are templates, namespaces, classes, and probably other things I don't know about. What is the function of one of these compared to the others? Ζρς ιβ' ^¡hábleme! 21:23, 4 March 2009 (UTC)

Each function will have a slightly separate way of working, or will exist because they are in use by a sector of people who would prefer that 2 otherwise identical functions remain separate. Coding is like hand-writing, whilst we might all write the same language everybody has their own style and way of developing. Here is a discussion around Classes V Namespaces for example (http://www.velocityreviews.com/forums/t456911-class-vs-namespace.html). ny156uk (talk) 22:28, 4 March 2009 (UTC)

Namespaces: otherwise every global name gets thrown into one big pool; in languages like C, without namespaces, you run the risk that you (or one of your colleagues, or one of the myriad of authors of libraries you're using) will coincidentally use the same name as you do, and you'll accidentally refer to the wrong thing. If you're lucky you'll get a type incompatibility error when compiling; if you're not, you'll end up calling the wrong get_count() or whatever, which can be a very unpleasant problem to find and fix. So namespaces are a good thing. Large C projects, and C libraries, often have to adopt a strict naming policy for globally available names (e.g. you're writing the "transaction" module, so all your functions have to be called txn_foo() or whatever. 87.113.106.21 (talk) 22:34, 4 March 2009 (UTC)

Classes: well, that's the core bit that enables object oriented programming. You can do object oriented programming in languages that have no native support for it (I've lost count of the number of object systems I've seen implemented in C) but doing so makes for rather harder to follow code, requires discipline that's hard to keep up, and can be a bit fragile. If you don't want to do object-oriented programming, you just don't bother with classes. 87.113.106.21 (talk) 22:38, 4 March 2009 (UTC)

Templates: templates enable generic programming. That is, say you write code for a linked list of integers. But then you need a linked list of strings, and a linked list of floats, and a linked list of some complex struct. With templates you just write a linked list of <anyoldthing>, which means you've only had to write the linked list part once (for complex data structures that can be a big deal). Now, again, you can do this without templates and generics; in C you'd just have a linked list of void *, but that imposes the burden of casting things to the correct type on the caller; worse, that cast breaks type safety - so you can mess up and put a bunch of ints into a list, but then the code that pulls them out thinks they're something else entirely, and blithely casts the value it gets to the wrong type, which means what comes out is hopelessly garbled and wrong. Try that with templates and you'll get a compile time error (compile time errors are good; run time errors are bad, especially when your runtime is a mars rover or a nuclear missile). Templates give you the advantage of writing a general purpose thing once, but without the disadvantage of having to throw away type information. 87.113.106.21 (talk) 22:44, 4 March 2009 (UTC)

In short, you don't need any of the features that C++ adds to C; indeed, you can do anything in C if you really want: functional programming, lazy evaluation, exceptions, coroutines, tail recursion, objection orientation and inheritance, automatic memory management, generic programming, etc. But you end up with a bunch of scary macros and fragile cruft and some really strict rules for using them (rules that the compiler won't enforce). Frankly that scary stuff is all still there in C++, but you can mostly forget about it. Mostly. 87.113.106.21 (talk) 23:03, 4 March 2009 (UTC)

Other posters explained the specific features pretty well. I'll add that the basic point of C++ is to help keep very large projects (with a lot of programmers who come and go and who aren't necessarily familiar with the whole code base) from getting disorganized. All the weird tensions and trade-offs in C++ were driven from experiences in such projects. If you're new to programming or mostly working on small or solo projects, it's not a good language to start with. 13:26, 5 March 2009 (UTC) —Preceding unsigned comment added by 207.241.239.70 (talk)

Putting Two .jpg Files Into A Single .pdf

I made a nice looking document on MS Word 2007, with some gradients to make it look nicer, then when I exported to .pdf, I ended up with a .pdf file with stripes all over it, instead of a two gradients. Anyway, I decided to take the original .docx and (with no gradient) and export them to .pdf, then edit them with GIMP, giving me the effect I wanted. Unfortunately, GIMP will only edit one page at a time (it seems - as when I click the option to edit both, it adds them both as layers, which is not what I want). So, now I have two beautiful .jpg pages, but they are separate files. Now, my question is, how can I combine them as a single .pdf file, i.e. with two pages? I don't want to put them both back into a Word file as inserted images, as they will be smaller (because of the page margin, which is of course already included on the new .jpg files).

Vista taskbar problem

Resolved

I'm running Windows Vista (Home Premium version 6.0). The taskbar includes a little desktop button that takes me right to the desktop - very handy for me as I tend to work with a billion windows open. A couple of days ago, that handy little button disappeared, and I can't figure out why or how to get it back.

I know how to add items to the taskbar, but the desktop thing is stumping me. I can seemingly drag and drop any other object onto the taskbar, but nothing I have done can get that button back.

Find the Maximum of a Set

Given an array(set) of integers, how do the various computer languages go about finding the maximum value? More to the point, if they use a specific algorithm to do it, what is that algorithms complexity class? While on the subject of what certain built in functions do; is there any place where this information can be looked up for Ruby/Python/C++, etc? Phoenix1177 (talk) 04:40, 5 March 2009 (UTC)

Obviously, if the array is sorted, it's pretty easy. If it's just an array, then it will take O(n) time. Of course, integers can be stored in a binary search tree, and in that case getting the maximum integer takes O(log(n)) time - it's simply a matter of traversing the nodes to the right. I don't know of any specialized algorithm for finding maximums, nor any special data structure that works with an ordered set of integers to help find the maximum. --wj32 ^t/c 04:54, 5 March 2009 (UTC)

Although alluded to by Wj32 above, on a sorted array which includes maxindex (a count of items), the time taken to dereference array[maxindex] would be O(1). Sorted arrays implemented as linked lists and sorted arrays without a count of items would require traversing the array to the final item, with complexity O(n). Such arrays, however, would likely be quite rare. – 74  05:55, 5 March 2009 (UTC)

If it's an unsorted array, all you can do is make a linear scan through it, keeping track of the biggest number you've seen so far. There is a very detailed analysis of the complexity in Knuth TAOCP volume 1, using the method of generating functions, which iirc lets him figure out the probability distribution of how many times the "biggest number seen so far" has to be updated during the scan, etc. But the main point of the analysis is to show how to use the techniques on a very simple algorithm so that they can be used on more complicated algorithms later. 207.241.239.70 (talk) 13:06, 5 March 2009 (UTC)

Read from /dev/urandom and convert to binary

In a bash script, what's the simplest way to read 119 bits (or, if /dev/urandom can only be read an octet at a time, 120 bits) from /dev/urandom, express them in binary (in order to work with the individual bits as substrings) and store them in a variable? NeonMerlin 07:46, 5 March 2009 (UTC)

I find scripts like that very ugly. It's better to write a program in a more reasonable language, python or perl or whatever. It would probably be a perl one-liner using the "%b" format specifier to get binary out, but my Perl is way too rusty to write it for you, and anyway this sounds a little too much like homework. 207.241.239.70 (talk) 13:20, 5 March 2009 (UTC)

It is homework (for once), but it's a small part of a much larger project. The reason the shell script is a shell script is that it involves a large number of command line invocations, in iterated loops, with lots of options. I don't know how to invoke the command line in Linux in any non-shell-scripting language; even if I did, a shell script seems most logical. NeonMerlin 19:25, 5 March 2009 (UTC)

Fire suppresor for computers/servers?

Do dry-chemical/clean agent fire extinguishers really leave no damage to computers? Argonite can be (and it is) used on servers and other sensitive equipment, but my professor argued that such extinguishers can still damage them.

Is my professor right about that, or not? Blake Gripling (talk) 08:56, 5 March 2009 (UTC)

Well, there may well be reactions I'm unaware of, but I don't see how argonite gas it could damage computers. It's inert, and anyway, computers don't require oxygen to operate (unlike fire). In any case, a fire is bound to be far, far more destructive to a server room than argonite. You professor didn't offer any explanation as to how it would damage the computers? -- Captain Disdain (talk) 12:31, 5 March 2009 (UTC)

He only said that it is ineffective (perhaps based on his own experiences), and so do other types of extinguishers, practically leaving me and my mates with nothing to use for our defense/thesis. It is obvious that we can't treat a fire in a sensitive area such as a courtroom or a server as inevitable, right? Blake Gripling (talk) 13:07, 5 March 2009 (UTC)

Well, if argonite isn't an efficient fire extinguisher -- and I'd bet that has as much to do with how the system is set up as it does with the gas in question, because properly used, the argonite is going to replace all of the oxygen, and the fire pretty much has to go out -- that's a completely different thing; in that case the computers aren't damaged by the argonite, but by the fire that isn't going out. I'm not sure what his point is, beyond "fire bad" -- I mean, I don't think any fire extinguishing system is going to be 100% effective and prevent all damage. -- Captain Disdain (talk) 13:53, 5 March 2009 (UTC)

They don't require oxygen, but they do require air cooling. The environmental requirements specs for some server/comms grade equipment specifies a minimum air pressure, as lower air pressure means there's less air into which a heatsink can shed excess heat (and thus the cooling system is less efficient). Some high-end Sun servers, for example, ship with a barometer, and will shut down if air pressure falls too low (in practice this is only rarely an issue - only when the machine is installed in relatively high-altitude locations like ski resorts). Now I wonder what the specific heat of the extinguisher gasses is (I really don't know). If it is considerably lower than that of the air it has displaced, then that might compromise the cooling of the densely packed equipment, and maybe lead to dangerous or damaging overheating. Now I guess the power will be automatically switched off by the same fire alarm that triggered the extinguisher, but some will be held up by UPSes (and will still be engaged in the rather hot process of an ordered shutdown when the extinguishers go off). 87.115.143.223 (talk) 20:38, 5 March 2009 (UTC)

I'd be more worried about people than a bunch of servers. I remember some carbon dioxide being used in a server room and these firemen rushed in and promptly fell down, they had to be dragged outside into the fresh air to recover. The computers weren't affected but the pressure caused some damage to the ceiling.Dmcq (talk) 13:38, 5 March 2009 (UTC)

want to save HTML of current page from Firefox 3

I'm looking at a particular web page and want to save the HTML of the page I'm looking at from the browser into a file. "View page source" does not do this--it sends a new request to the server which can send back different contents than it did for the first request. I want to save the stuff that's already in the browser's memory (I know it's there because Firebug can see it). I could take a screen shot but that loses a lot of information. Any other ideas?

That sounds like faulty behavior; I would not expect "View source" to return a new copy of the page. I tested this in FF 3.06 with a page that I know has changed and it displayed the source of the version already loaded (not the most recent version). On the other hand, *updates* since the page was fetched may or may not appear (some type of Ajax/XMLHTTP modifications). Presumably you could select that which you wish to save and copy it into a text file—again, you'll lose some information (the formatting) but the actual text should remain. If the error report contains diagnostic HTML comments (like the Wikipedia rendering statistics) then those will be lost, however. – 74  17:25, 5 March 2009 (UTC)

Look for unsecured wireless hotspots - I used one in a pub in London a couple of months back. All it cost me was a couple of pints that I would have had anyway. If you want access "on the road", you are probably better off looking for a mobile phone contract with an inclusive 3G data package. All the mobile networks offer such deals (though not to pay-as-you-go customers). However, the deals are pretty expensive once you go over the download limit. Also, your laptop will need a HDSPA slot in which you stick a SIM card, or a bluetooth facility, or you will have to get a USB dongle from network. Astronaut (talk) 16:36, 5 March 2009 (UTC)

serving SVG to FF and png to IE?

Hi all!

I have some nice logos that look great in SVG, but when I turn them into small png's (either by shrinking them from their original size in a program like Paint.NET, or by having the browser shrink them on the fly), they lose lots of detail. I would like to have some way of displaying the nice SVG to non-IE browsers, and the png replacements to IE, but I can't find a way of doing it. Wikipedia's solution is to create a png every time there is a svg file and display that to all browsers. Can anyone help me? --richardmtl (talk) 16:26, 5 March 2009 (UTC)

A simple javascript function can change the "src" of an image. I'd suggest something like:

1. use HTML to set the image to the png (works for everyone)
2. use javascript to detect non-IE and modify the "src" by switching to svg

This has the advantage of failing gracefully if javascript is disabled. You could also make use of CSS to show/hide alternate images, or use a hypertext preprocessor to create "customized" versions of the page based on the client's browser. – 74  17:09, 5 March 2009 (UTC)

excel macro help

I've never even tried to use a macro before, so i'm stumbling quite a bit here. I'm working on a project that requires that I input 0s and 1s into thousands of lines of a spreadsheet as one phase of an audit of documents at my office. To make things visually easier to handle, I would like a macro that automatically turns the font green in a box containing a 1. I found this code, but I can't seem to make it work. I tried replacing (1, 1) with (ActiveCell), still no good. Help? 208.73.108.118 (talk) 20:35, 5 March 2009 (UTC)

I don't have my compiler on hand so I don't know if this will work but try:

Sub Example()
    With ActiveSheet.Selection
    For i = 1 to Selection.Cells.Count
        If .Cells(i).Value = 1 Then 
            .Cells(i).Font.Color = vbRed
        Else
            .Cells(i).Font.Color = vbGreen
        End If
    Next i
    End With
End Sub

You have to select the cells you want to format before running. If it works, it will make all the 1s red and everything else green. You can also try conditional formatting. Hope this helps. Zain Ebrahim (talk) 22:16, 5 March 2009 (UTC)

Except this specific address shows you a page that looks just like the HSBC login page.
So is somebody using the Letraset address as a host or what? How does this work?
