Upload 8K 60 fps Coaxial cable

Does it 8K 60 FPS upload Coaxial Cable can cause slow share network cable?

I have a download speed of 81.00 Mbps and an Upload speed 11.34 using an HP laptop connected to Wi-Fi 5. I have a home modem Arris surfboard SB6121. I don't have AT&T fiber optic or faster technology types of internet. 47.234.198.142 (talk) 01:32, 24 February 2024 (UTC)

8K could use a lot of bandwidth, so yes, your streaming 8K could choke up the upload capacity! Graeme Bartlett (talk) 10:03, 24 February 2024 (UTC)

At the end of the day, a Coax cable is just a length of copper. A such, the whole cable industry is a series of scams, design to trick idiots into buying pricy cable. In actual fact, copper is copper, and regardless of the cost, it's the same darn metal! It doesn't matter what fancy baloney claim the cable manufactures claim, all cables are just the same copper strands inside. I hope this helps. Pablothepenguin (talk) 12:29, 27 February 2024 (UTC)

The "8K" thing is probably nonsense. Copper wire does not have any effect on download speeds, electrons always travel down these things at near relativistic speeds anyway. Pablothepenguin (talk) 12:30, 27 February 2024 (UTC)

Sure it matters. The speed of the electrons is actually pretty low, it's the speed of the electromagnetic wave which is relativistic. But that is only related to the latency of the cable; what OP cares about is the bitrate, which is related to the frequency of the EM signal you can send through the wire without excessive attenuation, which in turn depends on the resistance, inductance and capacitance. See telegrapher's equations. The thickness and electromagnetic properties of the insulator between the copper core and the copper sheat of the coax cable matter. PiusImpavidus (talk) 13:18, 27 February 2024 (UTC)

And the end connectors. Cheap ones make a bad connection, decreasing contact, increasing resistance, and reducing the signal. 12.116.29.106 (talk) 17:19, 27 February 2024 (UTC)

To address the OP's actual problem, although it's a bit old now: you have a Motorola/Arris Surfboard SB6121 (manual), a standard cable modem. 81 Mb/s is a decent download speed (although I once had Gigabit fibre to my front door.) How long have you been aware of slower speeds? Have you (or someone else) changed anything? Is the problem with the wireless? Remaining suggestions are concerned with this possibility.
Where are you getting your wifi from? I imagine you have a Wifi-enabled router or other device plugged into the Ethernet socket at the rear of the Surfboard. What make and type is it? How many other people are simultaneously using your wifi/router? More users generally = less bandwidth. Is your wireless connection secure (ie not acting as a wireless access point)? Have you tried plugging your HP laptop directly into the Ethernet socket on the Surfboard via a network cable? You may need to enable Flight Mode on the HP with (Fn+)F8 to temporarily turn off your wireless. Alternatively, turn off wireless interface[s] on the router/wifi device. Does it seem faster? If so, any reduction in speed is down to the wireless signal, the router, and/or other users connected to it. Re-connect the router to the Surfboard. Plug the laptop, via network cable, into an ethernet port on the router. Any difference? Unplug network cable, re-enable wifi. Any difference? MinorProphet (talk) 18:26, 8 March 2024 (UTC)

Windows 11 multiple desktops: app always across desktops

Windows 11 has (at last!) introduced multiple desktops. I know how to mark a window as being available across all desktops (either that window, or all windows of that app). Is there a way to set that whenever a particuar app is opened, it will automatically be available across all desktops? I haven't found one. ColinFine (talk) 10:44, 26 February 2024 (UTC)

Easter date list

Is there any tool that lists years of Easter Sunday occurring at any given date until very many millennia from now? The table at Robin van Gent's Easter calculator lists them until year 3000, and I have downloaded an external web application that makes lists until 4099, but I want to make lists of Easter occurring on a rare date (like 22, 23, 24 March or 23, 24, 25 April) until more than 10,000 years from now and in such calculation I use the van Gent's calculator. For example, if I want to make a list of every occurrence of Easter on 22 March, then I test Easter date on all years when 22 March is on Sunday and write down all years that actually have Easter on 22 March. But is there an easier tool to do this? --40bus (talk) 11:16, 26 February 2024 (UTC)

@40bus: Not an app, but this site [1] has a csv file you can download that lists all the Easter dates for 1583 to 4099. Since it is a plain text file you can just search for "March 22" to get those dates. RudolfRed (talk) 05:32, 27 February 2024 (UTC)

Since the exact date of Easter Sunday by definition is determined by a combination of the March Equinox and the occurrence of a full moon shortly thereafter, one could perhaps calculate the date themselves, by looking up future dates for the occurrence of full moons. Powerful computations have been run on our behalf to determine the precise date of the Moon's phases and other extraterrestrial phaenomena. Pablothepenguin (talk) 12:26, 27 February 2024 (UTC)

Easter is the first Sunday after the Paschal full moon. This date cannot be determined by astronomical calculations, because the Pascal full moon is not an actual astronomical event. As our article says "This "full moon" does not currently correspond directly to any astronomical event, but is instead the 14th day of a lunar month, determined from tables. It may differ from the date of the actual full moon by up to two days." CodeTalker (talk) 02:39, 28 February 2024 (UTC)

Our article on the date of Easter has all the information you need (or ought to have; I haven't checked). If you can program a bit, you can write your own tool to find the date of Easter in the far future. That is, assuming the rules won't change. PiusImpavidus (talk) 13:01, 27 February 2024 (UTC)

Python code for computing the date of Easter can be found here. To select and print out lists of years with Easter occurring on a rare date is then a very simple exercise.  --Lambiam 21:33, 27 February 2024 (UTC)

I have two books by Jean Meeus, Astronomical Formulae for Calculators and Astronomical Algorithms which do this, and a lot more. Unfortunately they are both boxed up for a move. I think the former has BASIC code for the calculations. The latter gives all of the details you need to write a program (for many astronomical calculations). One thing - you need to make sure that any program or algorithm is valid for the date range you want. Some of them are only valid to, say, 2099. Bubba73 ^{You talkin' to me?} 22:04, 27 February 2024 (UTC)

The cal utility (standard on most Linux systems) can also calculate the date of easter in a particular year: ncal -e [year]. Put it in a loop in a bash script to find interesting dates. It goes up to the year 9999. PiusImpavidus (talk) 10:39, 28 February 2024 (UTC)

Well, by main Meeus book was not packed up. Chapter 8 gives a short method for calculating the date of Easter. Some of these have been mentioned, but the book says:

• This method doesn't have the exceptions that the method by Gauss has
• The full moon is not the astronomical full moon - it is when the church says it is (a certain number of days)
• Likewise, the Vernal Equinox is not the actual day - the church dictates it to be March 21, but the real one can be 1 or 2 days from that.
• This method is good for the Gregorian calendar for 1583 onward.
• It cycles in 5,700,000 years. Bubba73 ^{You talkin' to me?} 02:31, 1 March 2024 (UTC)

  So I got at least the last bit right (see the last sentence at archived RD topic Coincidence of Ash Wednesday and Valentine's Day).  --Lambiam 13:53, 2 March 2024 (UTC)

  • Right you were. Bubba73 ^{You talkin' to me?} 02:46, 3 March 2024 (UTC)

ChatGPT detector

Hi all--I need your help. I would love to hear your advice on what the best ChatGPT detectors are. A student submitted something and it's not theirs. GPTZero flags it as 96% plausible that it's AI-generated, but our administrators want us to run three checks with different detectors. Can you please tell me which one(s) you would use? Thanks so much--and please ping me in your reply. Drmies (talk) 17:15, 27 February 2024 (UTC)

A telltale sign is a submission consisting of an introductory paragraph followed by an enumerated list of aspects or examples and a concluding paragraph, as seen here and here.  --Lambiam 21:49, 27 February 2024 (UTC)

Lambiam, thanks, but I know what they look like; I've seen dozens of those documents already, unfortunately. I think it's 100% likely, in this case, but I need three different checks in order to make my case and file the paperwork, and I wouldn't go through this trouble if the student hadn't done this already without my bringing the hammer down. Thanks, Drmies (talk) 00:15, 28 February 2024 (UTC)

This blog post at Orginality.ai compares ChatGPT detectors. Perhaps non-surprisingly, their own detector ranks numero uno.  --Lambiam 15:10, 29 February 2024 (UTC)

Need an iphone user to take a quick look at this

We are having difficulty finding another iphone user with an iphone bigger than the smaller iphone SE 2020 that I have. Most iphones are bigger. We only need a few minutes of your time for a {{sticky header}} test. If you have an iphone please have a look at this test:

• Wikipedia:Village pump (technical)#Request for comment from other iphone users

Specifically: Please tell us if sticky table headers work without problems in these sandboxes:

• Current styles: User:Timeshifter/Sandbox244#Test sticky-header (sortable)
• Proposed styles: User:Timeshifter/Sandbox243#Test sticky-header (sortable)

It should only take a minute to look at the table in that section. And another minute to report what you are seeing at the Village Pump. Please report there, and also tell us what iphone model you have. Thanks. --Timeshifter (talk) 01:34, 7 March 2024 (UTC)

Oracle SQL - using one case/when on multiple columns

I have a set of sales data that I want to de-normalize by fiscal year. For example, I would do SUM(CASE WHEN S.FISCAL_YR = 2024 THEN S.SALES_AMT ELSE 0 END) as CY_SALES, SUM(CASE WHEN S.FISCAL_YR = 2023 THEN S.SALES_AMT ELSE 0 END) as LY_SALES and so on. They're all bucketed that same way - by the two fiscal years - but some of them are very much more complicated than just bringing back a single field like SALES_AMT. What I am wondering is if there's a way to introduce a case statement and have it apply to multiple columns being returned. For example, a case statement that said CASE WHEN S.FISCAL_YR = 2024 THEN... and then listed a bunch of columns to return that were all for 2024 and then another case statement for 2023's columns. I feel like it would make the SQL much easier to update and error check. I've done some searching, but the responses seem to be similar but different problems involving subqueries to different tables. I have everything in one table and the fiscal year is already a field, so it seems doable, but I can't get the syntax to work correctly. Matt Deres (talk) 14:55, 29 February 2024 (UTC)

Your query does not place current and last year sales side by side. It places a zero in one column and a value in the other. Each entry on a different row. I would union two subqueries. I don't know your end task, but I would do it like:

select * from mytable where fiscal_yr=2024
union
select * from mytable where fiscal_yr=2023

That is a starting point. Now, you can change the * in each subquery to get what you want. For example, you can select sale_amt as cy_sales_amt in the first one and sale_amt as ly_sales_amt in the second one. You need to have the same number of columns, so you will actually do:

select sales_amt cy_sales, 0 ly_sales from mytable where fiscal_yr=2024
union
select 0 cy_sales, sales_amt ly_sales from mytable where fiscal_yr=2023

Now, it is easy to include whatever columns you want. Just make sure both subqueries have the same fields in the same order. 12.116.29.106 (talk) 13:25, 5 March 2024 (UTC)

It does place 2024 and 2023 side by side. If I sold 10 hamburgers in 2023 and 14 in 2024, it would have CY_SALES of 14 and LY_SALES of 10. This then makes it very straightforward to compare the two amounts in Excel or where-ever. Your method would place hamburgers on two rows, taking up extra space and complicating comparisons. Matt Deres (talk) 15:57, 6 March 2024 (UTC)

iPhone users 2

Just wondering whether any other iPhone users failed to get their usually very reliable reminder to put the bins out tonight. Something to do with it being 29th February maybe? Shantavira|^{feed me} 18:34, 29 February 2024 (UTC)

You might want to specify what app you are using for the reminders. RudolfRed (talk) 04:11, 1 March 2024 (UTC)

It's a standard app called "Reminders". Shantavira|^{feed me} 10:19, 1 March 2024 (UTC)

If it's a leap year bug and you only care about you thursday bin (trash/recycle day) reminder, you will probably have to wait until 2052 to see if it recurs. -- Tom N talk/contrib 02:58, 4 March 2024 (UTC)

What does it mean when a URL starts with numbers?

Is it an IP address? Example: http://24.75.48.45/website/sesssite/addisonlist.html

I found this URL on Addison (Q940269). Kk.urban (talk) 03:25, 7 March 2024 (UTC)

@Kk.urban, that's an IP address. It goes straight to the computer without using a Domain Name System (a sort of phone book for which IP address is behind a normal domain name). You can look up the numbers using WHOIS to find out which Internet service provider currently has that IP address, e.g., at websites like https://www.whois.com/whois/24.75.48.45. WhatamIdoing (talk) 03:58, 7 March 2024 (UTC)

@WhatamIdoing If there is a website at an IP address, does that mean there has to be a domain name with letters and an extension like .com or .uk? Kk.urban (talk) 05:00, 7 March 2024 (UTC)

No, that's not actually a requirement (just good sense, because it's easier to remember a name than a string of numbers). WhatamIdoing (talk) 05:27, 7 March 2024 (UTC)

There are a number of services which you can use to do a "Reverse DNS lookup"; that is, to find any domain names that map to a given IP address. Google that phrase to find some of them. The particular IP address in the OP does not appear to have any domain name associated with it as far as I can tell. CodeTalker (talk) 07:05, 7 March 2024 (UTC)

Back in my day, all website addresses were numbers. 05:11, 7 March 2024 (UTC)

When was your day? The ARPA internet used host names in 1971.^[2] The earliest version of the IP protocol, using internet addresses with a fixed length of four octets (32 bits), is from 1980.^[3]  --Lambiam 11:51, 7 March 2024 (UTC)

This is based on my memory of first using the Internet in 1994 or '95 was that every URL you went to was a four-octet number, not an alphanumeric name. Bubba73 ^{You talkin' to me?} 22:10, 7 March 2024 (UTC)

This was before the summer of 1994. At a terminal or dial-in connection you would Telnet to an IP address. There you would see something like a Unix file structure. Bubba73 ^{You talkin' to me?} 00:04, 8 March 2024 (UTC)

"The URI syntax and URL forms have been in widespread use by World-Wide Web software since 1990." ^[4]  --Lambiam 09:09, 8 March 2024 (UTC)

The URI syntax includes URIs using an IP address (not just those with a domain name).

I remember File Transfer Protocol (FTP) being the most popular way to exchange files around 1990 (and that may be what @Bubba73 is remembering), and it could always, and often did, use the IP address. WhatamIdoing (talk) 19:11, 8 March 2024 (UTC)

Telnet is different from WWW because it doesn't use URLs, but the telnet target can be either a domain name or an IP address. Often telnet is used to reach another machine in the same organization, and organizations often don't bother to set up a DNS server for internal machines, so that may be the origin of the perception that only IP addresses were used with telnet. DNS was certainly well established before 1994.

Now if you want to reach back into history, when I started using email around 1979, we used bang paths. There was no Internet; each machine connected directly (usually via dialup) to a small list of other machines, and to reach a given destination you had to specify the exact sequence of machines that needed to be traversed to reach it. That was a real pain. CodeTalker (talk) 19:33, 8 March 2024 (UTC)

I don't see it mentioned, but there are many IP addresses that host services, such as web pages, without a host name. That is on purpose because the desire is to only make the services available to people who know about them. Further, they don't host the services on standard ports. Web pages are served on port 80. So, http://24.75.48.45 will go to that computer using port 80 (http = 80). But, to hide a web page, you would put it on something like port 514 and people would have to use http://24.75.48.45:514 to get to it. Further, DNS usually implies "Public" DNS. That isn't the only DNS. A group of people can set up a private DNS that only they use. Then, they can make up their own host names that nobody else has. For example, I could make bozo.xxx go to any IP address I like on my private DNS. I don't have to register it with a public registrar and pay for it (and hope it is available). Another example, wikipedia.org on public DNS goes to 200.80.154.224. But, I could setup a private DNS and send it to 24.75.48.45. Then, if you happened on one of my web pages and clicked a link to Wikipedia, you would use public DNS and go to the normal web page. I would click the same link and go to a different computer that may or may not have anything to do with Wikipedia. Why would anyone do this? It is commonly referred to by the blanket term "dark web." It is simply the Internet services that are not mapped to public DNS host names because they don't want it all to be public. 75.136.148.8 (talk) 12:05, 7 March 2024 (UTC)

Internet being jammed

I believe I've been hacked somehow, even though when I run Malwarebytes on my laptop it doesn't show any malware. Whenever I go to work or shop online, my Internet keeps going out. Wifi signal is fine, everything shows up fine on the router. Weather is not a problem. This only happens when I go online. I think the problem originated with my cell phone some time ago (I think someone was listening to me through the phone, I would get calls at very specific times whenever I made a sound), but I factory reset my phone and it's persisting with my Internet. Of course I don't know who is doing this or why, but when I hard reset my phone the problem goes away for a few minutes, then boom, it happens again. I am leaving my phone (for now) factory reset. Any idea what's going on and how I can fix it? I know how to work a computer but I'm not advanced or anything (ie no coding skills or network skills). Thanks. Therapyisgood (talk) 14:50, 8 March 2024 (UTC)

It could be due to some bad add-on/extension for your browser. If you look at your browser's menu you should find an entry for tem. Try switching off any you don't need. NadVolum (talk) 15:20, 8 March 2024 (UTC)

It's happening to multiple computers in the same house. Therapyisgood (talk) 15:45, 8 March 2024 (UTC)

I'd say it's very unlikely to be a result of a hack. Sounds like there is a problem with your router or modem. First step would be to power cycle both of them. I'm unclear however about why you mention your phone. Your phone has nothing to do with your computers' Internet connections, unless your computers are connecting via a hotspot on your phone. CodeTalker (talk) 19:36, 8 March 2024 (UTC)

(edit conflict) Concentrate on only one device, let's start with your laptop, since I even Windows. Turn everything other device in the house right off. If possible, disable your laptop's Wifi (or enable flight mode) and connect the laptop directly to the router with an ethernet network cable. Power cycle the router and laptop (ie complete reboot). When the laptop restarts, without opening your browser, open a command prompt with Win and enter cmd.exe . Type ping www.ibm.com, press Enter. You should get three Reply from www.ibm.com in 0.37 secs (or so). Don't close the command prompt window. In your browser, can you access any site? Does the internet connection fail on any particular site? If it fails, switch back to the command prompt, press the Up arrow and press Enter to repeat the ping command. Does it still work, or do you get three Request timed out? MinorProphet (talk) 19:52, 8 March 2024 (UTC)
