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)[reply]

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)[reply]

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.

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)[reply]

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.

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)[reply]

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)[reply]

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)[reply]

@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)[reply]

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)[reply]

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)[reply]

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)[reply]

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)[reply]

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.

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)[reply]

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)[reply]

  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)[reply]

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

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)[reply]

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)[reply]

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)[reply]

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)[reply]

We need some iphone users to look at the test sandboxes for some proposed updates for the sticky header template. See:

• Wikipedia:Village pump (technical)#Sticky header template for tables. Need iphone and Android testers

A general template tuneup would be welcome too. See anything that can be improved? Comment there please. --Timeshifter (talk) 12:21, 29 February 2024 (UTC)[reply]

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)[reply]

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)[reply]

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

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

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)[reply]
