Wikia and templates and images, oh my!

I would have asked this at the help desk, but I'm not sure if it's Wikipedia-related enough, even though I know Wikia uses MediaWiki. I'm attempting to add a category to a template (specifically, an image tag) so that all the images that transclude the template will put the image in that category. I found that adding it with includeonly tags seems to put the category name on the image's category list but does not actually seem to put all of the images in the category (a good 200 are listed but I know I tagged at least 500 by this point). Is there something I'm doing wrong or is it a lag of some sort? Thanks for any help. - Purplewowies (talk) 01:32, 17 January 2014 (UTC)

Yes probably a lag. The job queue is often pretty long you can see it at [1]. You could try doing a WP:NULL edit on some of the pages. This should recalculate the categories and you can use that to test the templates working correctly.--Salix alba (talk): 00:41, 19 January 2014 (UTC)

Net Neutrality

Hello. I have been hearing a lot about net neutrality in the US. I was wondering, if the carriers are allowed to discriminate what traffic they allow, would it mean the end to hosting on a personal server? For example, if I have comcast and I go to a friend's house and she has some other carrier, will I still be able to ssh to my computer or will that not work anymore? Thanks! 24.128.61.100 (talk) 04:40, 17 January 2014 (UTC)

No answers yet, so I'll bite...

Today, many IP addresses are globally unique and globally routable. This is an emergent property: the internet protocol allows connectivity across multiple networks; and we have a situation in which many networks exist across the globe, and all choose to connect together.

Some day, it may be the case that many networks choose not to connect together. Or, they may provide connectivity at a very sluggish speed.

The Internet is a complicated piece of technology. As of 2014, nearly "everyone" agrees that there is one internet. Specifically, this means that we all defer to one organization (IANA) to provide canonically correct unique addresses. But the technology that underpins the internet protocol doesn't require that structure at all! I can make my own domain server and my own IP allocation server, and build my own network, and write my own routing tables, and if my network becomes large enough to become useful, I can choose to charge other people money for access to my network. That's how the commercial internet developed - a bunch of private networks started charging subscribers for access - and most users ultimately wanted access to government networks that the ISP's didn't even own! When the marketplace became more competitive, these networks needed more value-add; so as a bonus, they also provided connectivity to other private networks... and today, almost all the networks are connected. The competitors had to start cooperating.

At least a few economists and theorists believe this business arrangement is unsustainable. For example, I took a class with this guy, Ramesh Johari, who has extensively published his work on the topic of network graph connectivity in an internet that is dominated by private enterprises who are actually competing against each other. It is a fascinating problem in game theory, because the decision problem is quite complex. Any organization - an internet service provider - has more value if it is better connected to other networks. But if an organization has more value, it will demand more aggressive terms for its peering arrangements; and it will try to put its competitors out of business - resulting in fewer networks to compete with or to cooperate with!

So, it is actually possible that in the next decades, we will find that an Internet is not sustainable from an economic perspective. That is, it may be unprofitable to have one, global, unified network. It may be more profitable for each individual company to maintain its own large network that is not connected to many peer networks. To an end user like yourself, that means that some valid IP addresses would not be routable for you.

Now the hard part is, where exactly is "neutrality" in all this mess?

Network neutrality explains some of the many ways that the term is used. The biggest problem is, everybody likes the way "neutral" sounds, but few people can agree on which policy decisions are actually "neutral!" Does "neutral" mean that every network must play by the same rules? Or use the same quality of service? Does it mean that a government auditor must enforce packet-latencies according to some set of requirements? What packet latency requirements are "neutral"? If an organization buys new gear improving speeds within its own network, must it be required to buy new gear for all its competitors (i.e. everybody in the world) so that all network traffic flows equally ? These are farcical solutions to a very complex economic problem. It will take many decades for public and private sectors to figure out what to do.

So in the short run, nothing is changing, and that means your friend's commercial internet service provider probably will continue to be globally routable. I can assert with high confidence that the round-trip travel-time for a packet from your house to your friend's server is slower than the round-trip packet-time from your house to Google's server. Even if your houses are a few feet apart. Even if you live nowhere near a Google data center. Carriers, phone companies, internet providers, and your home's Wifi router all already discriminate in favor of certain types of traffic. So we're living in a "not very neutral" internet already, but there has not yet been a loss of graph connectivity.

Consider what happens to a site like Wikipedia. Without net neutrality, either Wikipedia pays money to the ISP's - or their slice of the bandwidth is reduced (presumably heavily - or else nobody pays the premium). Since Wikipedia doesn't have a whole lot of money to bid on the available bandwidth compared to (say) YouTube - they'll inevitably wind up running really slowly by comparison. Worse still, there isn't (yet) one single place you'd have to go to in order to negotiate a payment. In principle, you'd have to negotiate separately with every cellphone provider, every cable TV network, every telephone-DSL provider and so forth. To reach global coverage, you'd need a massive army of negotiators working with ISP's around the world. You'd also have to figure out where it's worth putting the money. Do you fund good coverage to AT&T and let Sprint customers get slower coverage? Do you provide better coverage to West-coast US users or East-coast?

Worse still, if one service provider decides that they can make a lot of money by charging web site owners money - it's only a matter of time until someone realizes that they can offer consumers "free" Internet and live off of the fees that web site owners pay them. We know that "free" or "very low cost" services are popular to consumers - that's why our (free) broadcast TV shows are stuffed full of annoying adverts. So once one ISP goes that route - it's only a matter of time before the others do too.

In a world where most people use "free" internet and web sites pay the bills - how can independent web sites possibly survive? Wikipedia couldn't function in that world - so it would pretty much die without taking on advertising, paid promotional articles or switch to a pay-per-use model.

Pretty soon, the Internet starts to look like TV. Advertisers will start to drive content. TV shows are not made to make viewers happy - they are made to pull in advertising revenue. That's how the Internet will eventually end up. Gone will be the time when a bunch of enthusiasts can put something together in a garage and become the next Google - they simply won't be able to break into the closed-society of high-paying web sites - so the general public will simply never see them.

None of those consequences are very nice...each one destroys the beautiful thing that the Internet has become.

The IPv4 endpoint of a 6to4 IPv6 address

Hello, I have a dynamic IP that I have been using for years. When the internets went all magic and changed to IPv6, my IP starting messing with me. I never received a IPv6 address for about a year, then started getting them sporadically. Recently, I seem to get one about once every two weeks (I receive a new IP every 8 hours when my dial-up IPS disconnects me, I leave my connection always on and have it auto-re-dial when disconnected). About once a month, I receive an IP that flips back and forth from IPv4 to IPv6; I know it is the same IP because the WHOIS of a IPv6 lists my IPv4 address and I know it flips back and forth because I use "special:mytalk" as a sandbox (so I could be on my IPv4 talk page/sandbox and then an hour later save an edit and it goes to my IPv6 address which WHOIS traces back to the same IPv4). So my questions are: 1) why do I receive an IPv6 address only some of the time, and 2) why then does it flip from an IPv4 address only some of that time? Rgrds. --2002:4055:D812:0:0:0:4055:D812 (talk) 17:09, 17 January 2014 (UTC)

You must have an IPv4 address all the time otherwise a big chunk of the internet wouldn't work for you and you couldn't use 6to4. Also it sounds like you are conflating issues which makes it difficult to diagnose anything. You could be connecting to wikimedia servers by IPv4 because your connection currently has not managed to obtain an IPv4 address by any means it's set up to or you could be connecting to wikimedia servers by IPv4 because you browser for some reason chose it over IPv6. Rather than confusing yourself with how you connect to wikimedia servers, you should first better diagnose whether you have a working IPv6 connection all the time or what.

For example, try pinging a host on IPv6 (ping -6 ipv6.google.com). Even better, work out from you router or whatever else is getting the IPv6 address whether it always has a public IPv6 address or what. Once you've worked out the state of your internet connections IPv6, you can then either move on to trying to work out why you sometimes connect to wikimedia servers via IPv4, if it really matters; or work out why your internet connection doesn't always have IPv6 (a problem with the relay or your router perhaps). At a minimum, you should at least test with another host, e.g. try accessing [2] and [3].

BTW, the internet never went all magic and 'changed to IPv6'. Sadly, many servers let alone connections still don't have IPv6. But some have had IPv6 for a long time. I started using IPv6 via a tunneling service in ~2007 which was in some ways fairly late (although root servers only got IPv6 in 2008). You may be thinking of World IPv6 Launch Day in 2012 when a number of major websites (including content mirroring providers/CDNs) added AAAA records for their main websites with the intention of leaving it on permanently. This meant these services were accessible by IPv6, so those with IPv6 may have accessed them via IPv6 depending on the set up of their browser and/or OS.

But many services did not take part and as I've said, a number already had AAAA records by that time so were alreadt accessible via IPv6. And a large number of connections still don't have working IPv6 so are still using IPv4 hopefully without issue. (One of the reason it took so long for these major services to enable IPv6 was not so much because their backends couldn't handle it, but because they were concerned that misconfigured hosts with IPv6 that wasn't working properly would have problems accessing their services. Google for example had ipv6.google.com for a while. And they even had a way of adding AAAA records for their services even before the IPv6 (trial) day, see IPv6 brokenness and DNS whitelisting.)

Reviving dead torrents

I've been trying to download a "semi-dead" torrent on BitTorrent for a couple of days now. 404 MB out of the 5.57 GB size 320 kbps discography has been downloaded and I've been waiting for several days for the rest to finish downloading. No progress.... The torrent is only several years old by the way. I read that adding trackers would help bring back to life a dead torrent by adding seeds. I've tried to find online and add more trackers, but that didn't work for me. Is there any way that my torrent can be revived? What are some ways to bring a dead torrent back to life? Willminator (talk) 03:23, 18 January 2014 (UTC)

Well, the general rule for torrents is that they're useless or pointless if there aren't any seeds supplying the download. Blake Gripling (talk) 06:01, 18 January 2014 (UTC)

Right, without uploaders there is no downloading. But the OP is asking how to find more seeds, and indeed, adding trackers is one possible solution for that. Sometimes they are dead, so there is no work-around here. Maybe try another torrent with the same name. Possibly someone created a torrent of the same medium, maybe with a lower quality, but more seeds. BTW, several years old is a lot of time when it comes down to the internet. OsmanRF34 (talk) 14:33, 19 January 2014 (UTC)

(edit conflict) A tracker keeps, er, track of who is downloading and hosting (leeching/seeding) a torrent. If nobody is seeding, the odds are usually very low that the pieces of the torrent held by the leechers add up to form a whole. Adding more trackers looks at your peers (whether seeders or leechers) and checks to see if their torrent has other trackers associated with it (if you look through properties, etc. of a particular torrent you'll likely see it's associated with several). If the new trackers have been keeping track of seeders the original wasn't aware of, then great! But if that doesn't work -- and assuming your router isn't filtering out important ports -- you're kind of out of luck unless one of those seeders appears (but it's not unheard of). As OsmanRF34 points out, there are often multiple torrents with similar names associated with the same index/tracker. This is good for providing options, but bad because even if two are functionally identical, searching for trackers for one won't pull in those downloading/seeding the other. --— Rhododendrites ^talk |  14:41, 19 January 2014 (UTC)

Your best bet is probably to ask the band who's music it is to seed it. If they made a torrent, they must have been interested in distributing it in that fashion at one stage so maybe they still are.

If it's not the band itself that's doing it, but it some sort of public domain or creative commons or authorised bootleg recordings or similar content, you can try looking at forums where there's interest in this sort of thing (archive.org may be a decent bet in general but there are likely specialised forums depending on what precisely the material is) and seeing if you can find someone with the content able to seed. In particular, see if you can find the person who originally contributed the content and where they first released it, there's often only one or a few places.

Of course if you're downloading copyright violating stuff, you may be SOL since contributors of such material are often intentionally difficult to find.

I would like to know the details of the connection too.

Google maps light ?

When, in Google Chrome on Windows 7, 32-bit, I type a restaurant name as a general Google search term, it shows me a nice little preview map indicating the locations of that chain in my area. So far so food. Next I pick on the little map in the hopes of getting a full-sized map of the same thing, where I can zoom in and drag to find the names of local streets etc. This is where it all goes bad. Instead of what I want, I get a map showing every "point of interest" in the area, with pop-ups listing reviews of the restaurant, offering to recommend bicycle routes, etc. Even with nothing else running on my PC, this can take it down to a crawl. So, what's the easiest way to get what I want, just a larger version of the preview map, without all the bloatware ? StuRat (talk) 18:36, 18 January 2014 (UTC)

Setting mode page ???

This is the scoop. I have latest the UltraISO. I just tried to burn a DVD with it. It gives me this error: "DVD-R/RW media requires setting mode page to use DAO writing." Farfetched: there is a program "mode" in Windows\System32. I ran it but it does not seem to be relevant at all. It gives COM1, COM2 and CON parameters, nothing else. What is the meaning of it? Thanks. --AboutFace 22 (talk) 18:37, 18 January 2014 (UTC)

It is possible that the cryptic message simply meant that the DVD was not formatted. Once I formatted the disk the message disappeared. When I do System restoration disk the backup itself formats the disk, so with UltraISO I was under the impression it would do the same. --AboutFace 22 (talk) 20:07, 18 January 2014 (UTC)

DAO means disk-at-once, and the "mode page" is a SCSI mode page, I assume (your drive uses ATAPI, which is SCSI over ATA). If it was a DVD±RW and by formatting you mean erasing, then the error message is probably nonsense resulting from UltraISO misinterpreting an error code from the DVD drive. It is possible to format a DVD±RW disc (by writing a blank UDF filesystem to which files can later be added), but that probably isn't what you're doing. -- BenRG (talk) 00:23, 19 January 2014 (UTC)

OutfoxTV still listed in System Configuration Startup despite removal

hello, I was looking thru the Startup files in System Configuration (msconfig) and I saw "OutfoxTV" listed screenshot. I have never seen this before, and I assume it came from something I downloaded from CNET for free. Anyway, I couldn't find OutfoxTV at all on my computer, not even where it was listed as being (Program Files\OutfoxTV, which didn't exist). So I downloaded it, installed and removed it, then restarted my computer but it still shows up in System Config. I found it in HKCU and removed it with RegEdit, restarted, but it still shows up. Is it safe to say it'll be in the Startup list forever, even though I can't find it on my computer?Bananas9 (talk) 20:50, 18 January 2014 (UTC)

AutoRuns should help. --  Gadget850 ^talk 12:53, 19 January 2014 (UTC)

If you delete it from the registry using regedit (at the branch indicated in the location column of msconfig) and it then reappears, something else is putting it back. Maybe it is one of the other startup programs, but since you don't recall installing it in the first place, it is quite possibly malware which snuck it onto your PC in the first place and now refuses to let you delete it.

What came before the Unix shell?

If there were no windowing system at the time, how did users at that time interacted with the system? Only with punch cards or is there any missing link between shell and cards?? OsmanRF34 (talk) 14:29, 19 January 2014 (UTC)

Let's not confuse the user input device with the shell. Technically, you could scan a set of punched cards to provide input to bash or any other Unix-style shell. If you wanted, you could add a punched-card machine to provide very inefficient I/O for a modern operating system - even replacing mouses and touchscreens - because of the abstraction tthat serialization of data allows.

Before the bash shell there was a long line of similar shells. Before that, there were command-line monitor programs. Before that, most computers had very simplistic user-interfaces that were designed to be controlled by programmers - there were no users who didn't also program. Computers programs were a lot less interactive, because they were slow, and they shared resources; so in the very early days of computing, programmers wrote codes and ran them; the only input and output were stored files.

Files could be stored on a deck of punched cards, or on magnetic tape, or on another computer. For example, the IBM 1401 was commonly attached to the IBM 7090 so the bigger processor could be working at full utilization, while a programmer provided data on the smaller and cheaper system.

Since the early 1950s, the file system abstraction has allowed programmers to design code that is agnostic to the physical storage medium. An early program did not need to know whether its input came from a punched card deck or a serial magnetic tape. Of course, there have always been pesky cases of broken abstraction, and they were more problematic in the era when hardware limitations were much more severe. Nimur (talk) 16:18, 19 January 2014 (UTC)

• Quoting from our shell (computing) article: The first Unix shell, Ken Thompson's sh, was modeled after the Multics shell, itself modeled after the RUNCOM program Louis Pouzin showed to the Multics Team. Looie496 (talk) 16:36, 19 January 2014 (UTC)

• An interface that was more interactive than punch cards, but less interactive than video terminals, was the printing terminal. Some of these were teletype machines. One, the IBM 2741, was based on the IBM Selectric typewriter. Jc3s5h (talk) 20:27, 19 January 2014 (UTC)

Before the GUI windowing system (invented at Xerox's Palo Alto Research Center), people usually interacted with computers using dumb terminals. For example, the IBM 3270 and VT100 terminals connected to mainframe and minicomputers, and DOS like environments running on PCs. These were not really shells but command line interfaces where you type commands to make the computer perform an action such as edit a file, compile a program, or run a shell script (a collection of these commands in a file). The use of dumb terminals is far from dead, though it is more often done today using a terminal emulation program (PuTTY is one such emulator).

Before dumb terminals, there were teletypes which were used to produce programs and their input data on punched card or paper tape.

Wikipedia-like software for writing academic papers

Does anyone know if there is a way to use the wikipedia software to write academic papers? I find that it's easier if I use my sandbox, and then it generates a nice looking page with the footnotes and then references at the bottom...or have I answered my own question? Hires an editor (talk) 14:39, 19 January 2014 (UTC)

You can install your own instance of MediaWiki to run on your own computer. You can even configure it to keep all your data totally private, instead of sharing it like a public website. You can use it to write your own papers, or your own encyclopedia, or any other writing task that you see fit. Nimur (talk) 16:21, 19 January 2014 (UTC)

Bear in mind though that much of what you may regard as standard functionality on wikipedia, including part of the citation system comes from templates. Simply installing MediaWiki even with all the added extensions like cite.php may not give you what you expect from wikipedia. You'd need to install these templates on your own wiki which may take a bit of work since there's a fair few of them often dependant on a main template (although I believe this is changing with the rise of lua).

However writing it in your sandbox yourself here on en.wikipedia isn't a good idea. Beyond the fact you may not want to share this info so publicly, WP:wikipedia is not a webhost so you're likely to find your sandbox deleted at any time if you use it for that purpose. So if you do want to use a MediaWiki like system, it may be your best bet.

I think you're going to find that you have great difficulty getting your document into the format needed for submission. If you like the "wiki" style of doing things, I recommend [[LaTeX|Template:LaTeX]]. That can get you into difficulties too, but thousands of people have figured out ways of solving them. Looie496 (talk) 18:31, 19 January 2014 (UTC)

Likewise: In the long run, I think you would be better off learning the simple coding of LaTeX. It creates very professional results, which is why perhaps, so many professionals use it for creating their academic papers.--Aspro (talk) 18:33, 19 January 2014 (UTC)

LaTeX is powerful, but it's quite clunky compared to the numerous alternatives. I would only recommend learning and using LaTeX if you are working among a community who also uses it. LaTeX is intended for typesetting printed documents. That is, the final product will go on paper. Compared to MediaWiki markup, HTML, or even just a hyperlinked Microsoft Word document, LaTeX produces very poor digital document. Its file-format is esoteric; its rendering system is slow; its hyperlinking featureset is limited; embedding dynamic content, like an animation, video, or software simulation in the document is nearly impossible; its portability to modern operating systems (like Windows, Android, iOS, for example) is very poor. Many people work around this limitation by rendering, and then exporting, rendered LaTeX documents to PostScript (or Enhanced Post Script); or to PDF; this yields a static document that cannot be easily reflowed, re-edited, or re-typeset on different types of screens. Nonetheless, many people still use LaTeX - especially in fields related to mathematics - because some authors find LaTeX syntax for mathematics very convenient, and they do not wish to learn how to use a LaTeX plug-in for Microsoft Word, or MediaWiki, or Open Office.

If you're looking to author journal submissions, check your journal's recommendations for digital document formats. Many journals now prefer a rendered PDF document, or a Microsoft Word file, rather than raw TEX markup. Nimur (talk) 18:45, 19 January 2014 (UTC)

In the spirit of full disclosure, I have a well-known bias against LaTeX, as evidenced by our archived discussions on this topic. In my defense, I have learned and used LaTeX extensively - so intensively that I can identify its shortcomings. I have successfully compiled the LaTeX processing pipeline from source (...and many more times, I have tried to do so unsuccessfully). I have backported document layouts and TeX wrapper scripts; I have operated all the bibtex workarounds and tex2html hacks too many times to count. I freely admit that the TeX-style mathematical equation syntax is quite convenient. Everything else about TeX is stuck three decades behind its competition. Mathematicians and physicists would do the world a favor if they would write HTML instead of TeX. If mathematicians desire more compact syntax for writing mathematical formulae, they ought learn MATLAB or FORTRAN or C, because there is not an equation yet expressible in human-readable format that cannot be equally-well-represented as a valid computer program. If mathematicians desire more "beautiful" equation rendering, they ought to learn how to write better style-sheets; and if there is truly something deficient in the rendered document, then they out to design a specialized HTML layout engine.

Ugh! LATEX does exactly what you tell it. Academic journals will thus, be happy to accept it for the foreseeable future or until microsoft comes up with something better. Why when one can create Latex doc's should one have to learn all these other things? LATEX for academics and researchers who (think they) don't need it--Aspro (talk) 19:12, 19 January 2014 (UTC)

Do you find it surprising that your link is a PDF document, and not a TEX document? Or, that when I view it on my 64-bit Unix supercomputer, the document's footnotes are not hyperlinked? This document's author painstakingly crafted \ref links, and then destroyed their functionality by rendering to a not-very-portable-document-format. The author could equally have typed "Footnote 1” in a plain-text document. I could then set my font to Computer Modern, and the document would be equally functional, and use fewer bytes.

To clarify, I didn't intend to give a ringing endorsement of LaTeX. It has huge advantages over MediaWiki, but in the modern world I believe there are numerous better alternatives. Looie496 (talk) 19:24, 19 January 2014 (UTC)

Thanks for clarifying. There may well be, better applications than Latex but we (I and every-bodies else’s dogs) would be interested in examples, rather than a 'belief' that such other applications exist. Then we can discus them and so answer the OP's question more fully.--Aspro (talk) 20:14, 19 January 2014 (UTC)

The OP asked for "Wikipedia-like" software - which would be a private instance of MediaWiki. I have used the same set-up for documenting hobby projects and collaborative projects. Sometimes, wiki-syntax is exactly what I need for document preparation, instead of a word-processor.

If the OP is looking for alternative word-processors of the more conventional variety, there are numerous choices. Microsoft Word is the obvious market-leader; and OpenOffice/LibreOffice are free software alternatives. These offer many of the advantages of TeX, with generally better usability and better platform portability. If your primary computer runs iOS or OS X, Apple's Pages software is very convenient and is now available at no charge. Mathematicians who need symbolic mathematical formatting, but also need to do useful work, can purchase Waterloo Maple - which, in the hands of a skilled operator, produces fantastic documents that can also execute complex calculations.

If what you must have is a mark-up language (as opposed to a word-processing software tool), there are many alternatives: other mark-up languages, like XML, MathML, HTML, or Wiki syntax, or even JavaDoc; all of these are better defined than TeX (in the sense of having a complete formal grammar), and that encourages documents that are more well-formed than TeX. Nimur (talk) 09:39, 20 January 2014 (UTC)

I've been using LaTeX for more than 20 years, and there are a number of (what I consider) good reasons for it. All journals and conferences I work with accept either LaTeX or LaTeX-generated PDF, and they provide LaTeX style files that make it easy to conform to their typesetting requirements. Typically, they even suggest LaTeX as the preferred format for preparation, even if they want the result in PDF. Secondly, LaTeX makes easy things (plain text, lists, definitions) easy and easy to get consistent. It makes hard things (mathematical typesetting) possible, and with some practice, bearable. LaTeX also is compact - the typing and reading overhead is a lot less than for XML-based formats. Thirdly, LaTeX is plain text. I can use my favourite text editor, which is both powerful, responsive, and unobtrusive. Being plain text, I can write code to generate LaTeX output - most of the tables in my papers are generated directly from experimental results using a bit of Python or AWK or shell. And again, being plain text, I can use standard version control software like git or subversion for both version control and collaboration. And thirdly, LaTeX is open both in theory, but also in a practical sense. I can still open and process files from 20 years ago. Even if, for some reason, the file won't compile anymore, I can still look at the source and typically get all of the content. And because LaTeX is an open and transparent format, I don't suffer from vendor lock-in - which is bad if the vendor is good, but catastrophic if the vendor goes out of business. Finally, LaTeX is pretty much standard in my field. Everyone can get it, it's free, and exchanging documents is painless (unlike documents that passed through, say, 5 different versions of Word). Now the fact that I use Beamer (LaTeX) for slides has to have something to do with stubbornness and irrationality ;-). --Stephan Schulz (talk) 10:18, 20 January 2014 (UTC)

Nimur, if you've used LaTeX extensively you must know that PDF supports hyperlinked footnotes/references and LaTeX supports them in PDF output. Why that particular document doesn't have internal hyperlinks I don't know, but it isn't because they used LaTeX and/or PDF. Also, distributing documents as PDF, instead of in editable source form, is not exactly peculiar to the TeX world. -- BenRG (talk) 07:06, 21 January 2014 (UTC)

They may accept it, I don't know whether all are happy about it. Consider these two guidelines from prominent journals [6] [7]/[8]. Both prefer Word or Wordperfect. The latter won't even accept the TeX file wanting a PDF (well I imagine they have no problems if you convert it to another format they accept like RTF or TXT). The former will accept the TeX file in addition to the PDF or PS for your final submission (it requires a PDF for the initial submission, I think most expect that to make it easier for reviewers). And while I don't know how old it is, they say they want it simple because 'converting LaTeX files to Word format relies on a DOS-based utility that converts to HTML as an intermediate format'.

Another prominent journal albeit with a narrower focus [9], doesn't mention TeX at all, and although they accept TXT, since they require an editable/modifable format and prefer Word, it's unlikely they accept it. Of course you could publish it to TXT or perhaps RTF yourself [10] like you're basically doing with Nature but the fact they didn't mention it suggests it's not something they wish to concern themselves with.

Sure some are happy with TeX [11], but clearly the idea all journals are happy with it doesn't seem to be supported when some don't even accept it and others seem to indicate it's not something they really like to deal with. This doesn't seem to be a new thing either. An article from 1996 in the same LaTeX journal you linked to above [12] says something similar.

Nil Einne (talk) 21:22, 19 January 2014 (UTC)

Nit: TUGboat is not a LaTeX journal, but rather a journal on digital typography with a focus on TeX in general. --Stephan Schulz (talk) 10:00, 20 January 2014 (UTC)

• To sum up: It looks like LaTeX will be the prime choice for the foreseeable future.--Aspro (talk) 00:22, 22 January 2014 (UTC)

Forgive me for being cynical. Yet, I wonder if some editors know (rather than believe or visa versa) that as Bill gates 'invented' all on his very own (not bought form other companies -as that is not microsoft's kosher version of history) the PC, the Word Processor, Spreadsheets, video games, the internet, computer viruses, the blue screen of death and everything else, then, therefore, one must only look to microsoft for the one's solutions (and assurance of future licensing problems, API problems, security problems etc,).--Aspro (talk) 00:57, 22 January 2014 (UTC)

Psiphon 1 fails to display HTTPS websites

Dear Wikipedians:

I set up a Psiphon 1 server. I logged onto my Psiphon server from another computer and browsed a few HTTP websites, they all worked well. However, when I attempt to browse an HTTPS website, I got an error page that says:

HTTP Error 501/Not Implemented.

I am wondering what is going on and how I can resolve this error?

Ubuntu in VirtualBox

Hello! I am trying to set up my Windows Server 2008 (among other things). I installed Oracle's VirtualBox and it seems to be working more or less OK. Then I tried to install Ubuntu Desktop. I downloaded it, unzipped it with UltraISO, copied the whole directory on a DVD, burned it and used the executable file there to install the OS. I hoped that somehow it will end up as the Guest OS in Virtual Box but this does not seem to be the case. It appears (I may be wrong) that it is now a third OS on this computer because I see it on Windows Boot Manager (black screen). I have now Windows Server 2008, Windows 7 and Ubuntu there. What did I do wrong and how to correct it? Thanks, --AboutFace 22 (talk) 01:44, 20 January 2014 (UTC)

It sounds like you have indeed installed Ubuntu directly onto your hard disk as a third OS alongside your two Windows installations. You probably now have the option to choose Server 2008, Windows 7 or Ubuntu at boot time. Unfortunately, you cannot switch between them without rebooting.

Ubuntu is not installed in the virtual machine (Virtualbox). To install it, you first need to create a virtual machine. Virtualbox supplies a few configurations (including one for Ubuntu) for you to start with, or you can create your own from scratch. Make sure your VM is created sufficient virtual hard disk space and sufficient memory - this suggests a minimum 5 GB disk space and 500 MB memory], though you will almost certainly want more if you want to run anything other than just the OS. Once configured, start Virtualbox and then start your virtual machine. The virtual machine's BIOS will detect that no OS is installed and at that point you tell it to look at the Ubuntu Desktop ISO file you downloaded or or the DVD you created. It will install Ubuntu to its virtual hard drives and then you're done.

As for removing your triple-boot Ubuntu from your hard drive, that is quite easy though you might have to do something with the Windows Boot Manager - I'm not sure what (maybe someone else can help with that). Astronaut (talk) 12:23, 20 January 2014 (UTC)

Thank you. I did create two virtual machines in VirtualBox: Windows 8 and Ubuntu BEFORE I installed UBUNTU from the DVD. It was easy. Unfortunately it did not give me that option you describe. I sort of expected it but it never appeared. I will try to read literature more closely. Ubuntu now appears in the Boot sequence and also as a program installed in Windows Server. It is in Control Panel==>Uninstall Programs. Thus it can be removed. Besides I know how to do BCDedit. I've done it many times. --AboutFace 22 (talk) 15:53, 20 January 2014 (UTC)

A virtual machine in Virtualbox is like a separate machine with its own BIOS, its own (and initially empty) hard disks, its own memory, etc. I recommend you read the manual - particularly '1.8. Running your virtual machine' - to read how to install an OS in a virtual machine. There are also video tutorials - just search on Youtube. Astronaut (talk) 18:53, 20 January 2014 (UTC)

Thank you, Astronaut. It is all very useful. --AboutFace 22 (talk) 02:31, 21 January 2014 (UTC)

How to find out if this tower has an OS?

typing on phone, sorry for grammar etc.

My boss wants me to get an old tower in working order. its a dell inspiron with a Vista sticker. When i crank it up, it warns me that the hard drive selfchecker has detected a possible problem with the hard drive. ging forward takes me to the Dell splash page and the Windows XP (?) splash page before it tells me Windows didnt shut down properly, would I like to start in safe mode, safe mode with network, safe mode with command prompt, last known working settings, or normally? All do the same thing; load for a while then loop backto the hard drive warning. doing a dell selfcheck with f12 fails because it cant find the partition. there is nothing in the cd drives.

I suspect there may be no os installed. how would i go about testing this? hoe do i fix it if he doesnt have the disks handy? wat else might be the problem? and why does a vista computer haven XP splash page? --Ye Olde Luke (talk) 09:11, 20 January 2014 (UTC)

If the XP splash screen displays there was/is at least 1 OS installed - i.e XP. Could be a dual-boot system but I would guess that it was downgraded from Vista to XP. Easiest way to check the drive is to remove it from the tower and plug it in another (working) tower or USB housing. Download Seatools (or whatever is appropriate for your brand of HDD) and run the diagnostics. Run chkdsk x: /r from the command prompt (where "x" is the applicable drive letter for the drive). If all goes well you should be able to browse the drive and partitions. You will be able to tell from the folder structure if it is XP/Vista. If there is more than 1 bootable partition you will need someone other than me to help you. The first step is to establish if the drive is not fubar otherwise you're wasting your time.196.214.78.114 (talk) 10:14, 20 January 2014 (UTC)

Another option which should at least get you to the point where you can look around for what the problem is would be to use a Ubuntu LiveCD/USB stick. It's a free operating system that will let you run the operating system off of the usb/livecd without trying to install anything. It's pretty easy to do, even. Without the Windows discs this may be the best way. And, of course, you could always install Ubuntu or another Linux distribution instead of Windows to avoid future problems caused by not having the discs (or by not having an up-to-date operating system). Regardless, I would also recommend running diagnostics on it. Even if you format and reinstall the OS you could still have hardware issues (e.g. a bad hard drive). --— Rhododendrites ^talk |  15:01, 20 January 2014 (UTC)

Since I don't have a second tower I could easily plug the harddrive into that isnt currently in use, I'm going to attempt the Linux workaround just to get inside the machine without having to take it apart. Any recommendations on diagnostics I should prioritize once I'm in the system? I figure harddrive-related things are the most obvious target.

Also assuming this doesnt work and i have to insert the harddrive into a new tower; the second tower won't be in danger right? Do hard drives just work in any tower, or do I have to keep the same make/model/providing company? Just dont want to take out another company computer. --Ye Olde Luke (talk) 16:04, 20 January 2014 (UTC)

Is there something special about that tower? Otherwise this seems like an incredibly inefficient way for your boss to use the salary you are being paid. Looie496 (talk) 16:21, 20 January 2014 (UTC)

You're obviously a techie ;-). But the point is that a reasonable tower sells for about US$500, so unless you are very cheap or "there anyways", from an economic point of view, you should probably not fix machines that take more than a small single-digit number of hours to fix. --Stephan Schulz (talk) 20:05, 20 January 2014 (UTC)

I think i may have found the problem. i got ubuntu up and it works fine. followed these steps http://askubuntu.com/questions/317241/can-i-use-ubuntu-to-diagnose-hard-drive-or-ram-problems-in-windows but according to disk utility there is nothng under local storage. there are just no options except peripheral devices. oes that mean there is no OS installed? --Ye Olde Luke (talk) 20:22, 20 January 2014 (UTC)

No, that would mean it doesn't see a hard drive there. Might be a controller issue, might be a hard drive issue, but almost certainly not an OS issue (at least that wouldn't be your only issue). My instinct would be to tell you to run GParted rather than the Disk Utility to take another look, but that may just be based on my preference. At this point, now that you're [at least temporarily] a Ubuntu user, I would point you to the quite active and generally very helpful Ubuntu Forums, which will have a lot more OS gurus than frequent here, I think. --— Rhododendrites ^talk |  21:14, 20 January 2014 (UTC)

GParted agrees that the only partition is the one on the computer thumb drive. I admit to being slightly out of my league here, but I guess tonight I can ask the Ubuntu forums for help and see what they can do. Any further advice or recommendations on actions to take, let me know. Thank you all for helping me get this far :) 50.43.130.15 (talk) 23:04, 20 January 2014 (UTC)

It is sounding like either the disk controller is faulty, or much more likely the hard disk is faulty. You can check if it is the disk controller by trying a spare disk you probably have laying about - with an XP-era PC you probably don't want to buy a new disk just for this test. Assuming the disk controller is OK, you might want to talk to your boss about the usefulness of getting a new disk versus getting a new PC. As for the old disk, unless there is something critical on that disk I would suggest binning it, though do bear in mind your employer's disposal policy for such things. Astronaut (talk) 17:01, 21 January 2014 (UTC)

Yup, disk controller worked fine. Looks like there's something wrong with the hard disk. There's nothing important on said disk so I'm probably going to recommend he replace the hard disk. Unless I can find a way to get a factory restore through, so far I haven't found anyting that works except f2 and f12, both not very useful. — Preceding unsigned comment added by 50.43.130.15 (talk) 18:39, 21 January 2014 (UTC)

You really need to do the maths on the costs for this; like Looie and Stephan above, to me it looks like really bad financial sense.

• first you'll have to buy the replacement HD; at this age it's probably SATA, but it may not be able to use all of a modern SATA disk
• but then it doesn't have an OS; without the Dell recovery partition, you'll have to get a recovery disk from Dell (if they still have one for this model), for which you can get here
• now you have an ancient version of Vista; you'll spend half a day downloading and installing all the patches that have accumulated since the disk was authored
• at this point you have a working PC, with no software. Presumably you want Office and maybe something specialist (accounts, whatever). So you have to install that too, and (depending on what you need) pay for licences for it.

At the end of all that you have an old, slow machine with a poor OS. Based on the timeline of Windows Vista, this machine is probably 5 years old or more. Accounting wise it's written off - it's essentially worthless; getting it working won't make it worth anything. It would be one thing to resurrect this thing if you needed important business information off the disk, or if (perhaps for some obscure compatibility problem) you needed a reliable Vista machine. But if you just need a working desktop machine for someone to work at, this thing is a dead albatross. -- Finlay McWalterჷTalk 00:52, 22 January 2014 (UTC)

Focal Adhesion Counter

Hello. I count focal adhesions on about 200 photos a week with ImageJ. Is there a program that can automate this process so I do not need to manually contour the cells on my photos, measure the area of the contour, and summarize the number of focal adhesions? Thanks in advance. --Mayfare (talk) 23:28, 20 January 2014 (UTC)

For something as specialized as this, the only hope is to ask around among people who do similar work. Looie496 (talk) 03:33, 21 January 2014 (UTC)

Well you may be in luck - while I haven't worked on such things myself I have several colleagues who do automated microscopy analysis of cells and whom I could ask about this. The first thing you need to think about though, is how you define a focal adhesion in your images in terms which a computer can understand (i.e. absolutely specific and precise). You must precisely define a set of criteria that segregate the images fairly exactly into "focal adhesions" and "not focal adhesions". For example, what stainings do you have? Are focal adhesions in your images areas of colocalisation between two stains, do they have a maximum and minimum size, are they a characteristic shape etc.? You also need to contour your cells, but that is an easier problem as it is such a common thing to do that lots of pre-existing solutions exist.

The reason I am asking all this is that there are lots of programs which automate microscopy analysis, but they all have different capabilities, so I can't recommend one unless I know exactly what you want to do. If you get back to me with a) what your images are (are they 2d or 3d, confocal or wide-field, what stains do you have?) b) How you define both cells and focal adhesions, I can ask my colleagues whether they think any of the programs they are familiar with can possibly automate your analysis (a definitive answer is not possible, as so much depends on the quality of the data). A final word of warning; programs for advanced microscopy automation can be powerful, cheap or easy to use, and if you're very lucky indeed you get to pick two out of three. You may end up needing to spend many thousands of dollars if your requirements are sufficiently advanced . Equisetum (talk | contributions) 11:42, 21 January 2014 (UTC)

Hello, Equisetum. My images are 2D, wide-field, and stained with anti-vinculin and phalloidin. I define a focal adhesion as any streak (or dot) between 1 and 8 μm² in size. I define the cell border by eye. Thank you so much. --Mayfare (talk) 23:23, 21 January 2014 (UTC)

Great, thanks - I'll ask my colleague about this. It might be a few days before I get a chance to speak to him (he works in a different building), so if this question is archived by then I'll drop you a note on your talk page. Equisetum (talk | contributions) 11:56, 22 January 2014 (UTC)

Finding specific Wikimarkup

Many people on Wikipedia use relative image sizing of thumbnails to respect logged-in registered user's preferences where they have bothered to set them.

Unfortunately, over at our sister project Wikivoyage the discussion about introducing this image syntax seems to have both been sidelined and stalled.

I'm trying to find occurrences of "|upright=" within 20 characters of "thumb" so that I can see the earliest use of relative image sizing of thumbnails in a Wikivoyage article to bolster the case for introducing this syntax more widely there. Does anyone know of a tool or simple method I could use to search with, please? --118.93nzp (talk) 04:23, 21 January 2014 (UTC)

You could download the complete edit history of every article and search it locally. The file is only 320 MB compressed, but expands to 65 GB, so you might be limited in the tools you can use. Here's a short Python 2.x program that will search for approximately what you're looking for.

    import re, sys
    for line in sys.stdin:
        m = re.search('<timestamp>(.*)</timestamp>', line)
        if m: timestamp = m.group(1)
        m = re.search('<title>(.*)</title>', line)
        if m: title = m.group(1)
        if re.search(r'thumb.{,20}\|upright=', line) and title is not None:
            print timestamp, title
            title = None  # only print the earliest revision

You would use it like this:

   7z x -so enwikivoyage-20140117-pages-meta-history.xml.7z | python find_thumb_upright.py

Excel's incredibly annoying bounces to next page

I have been using Excel for years. I know lots about how to use it in complicated fashions but one thing I have never been able to find a solution for is that Excel is constantly bouncing me to the next page. What happens constantly is that any fast flick of the mouse (without any clicks) constantly pushes the page view to the next page over (to the right, without the cursor moving from where it was. It is consistent and always annoying and happens in no other program I know of. Please understand that this is consistent across different mac platforms with both regular and magic mice, as well as multiple PCs over the years with different mice, as well as a few different generations of Excel. Does anyone recognize what I a talking about and know of any fix?--71.167.166.18 (talk) 15:30, 21 January 2014 (UTC)

I've noticed something perhaps related in MS Word. I try to scroll down on a page so the part I want to read (the bottom of the page) is at the center of the screen, but doing so causes it to skip to the next page.

Test if Excel file is open using VBA

One of my VBA programs opens an Excel spreadsheet selected by the user. I want to see if the spreadsheet is already open, but all the online code examples use "On Error Resume Next", which I really don't want to use. Is there any other way to do this, short of writing an external COM function? Thanks! OldTimeNESter (talk) 15:55, 21 January 2014 (UTC)

You can do this by looping through the open Workbooks with a For Each loop:

Dim wb As Workbook, isOpen As Boolean
isOpen = False  ' not strictly necessary but adds clarity
For Each wb In Workbooks
    If LCase(wb.Name) = "filename.xlsx" Then
        isOpen = True 
        Exit For  ' don't bother checking any more once we find it
    End If
Next

One point to be wary of is the possibility that the workbook you want is not open, but another one of the same name (but in a different folder) is. You can check for this using the Workbook's FullName property. AndrewWTaylor (talk) 16:09, 21 January 2014 (UTC)

I didn't want to bug you with this, but the internet has not provided me with instructions at the basic level I need.
