I'm asking this here, since I presume we have more traffic here than on Wikibooks. SQL Exercises/The computer store has a number of exercises with inner joints that actually look easier without, such as "Select all the data from the products, including all the data for each product's manufacturer.". What's the benefit of adding INNER JOINT? The result should be the same, right? — Sebastian 07:34, 30 December 2015 (UTC)
Am I right that factorization of polynomials over finite field can be done efficiently (it's in ), while factorization of numbers is not in ? 213.8.204.30 ( talk) 16:55, 30 December 2015 (UTC)
A few minutes ago, there was an edit to Wikipedia:Sandbox (the time said 18:28 using Wikipedia's clock at the time of the edit) where the edit summary had the ugly characters ṇ̴̩̻̳̲̥̹̻͖̦̺̥͇͔̺̦̻̔͆̅ͯ̔̀͘wͮͮ̄̿̈́ͫ͋̂̈́͏̢̹͕̭̪̺̲̝̖̣̩ͅͅo̶͈̜̹̬̰̮̺͊͑̇̉͒ͫ̾ͬ̔ͮ̃́̀̔̉͗ͩ͟͝e̿̎̐̓̊̓̓̽̑̾ͭ̌̓͛͑̓̀̉̽͏̪̙̭̘̪̜̫͍͈̰͎̣̫̝̥̗͜͢r̴̢ͤͥ.

Why didn't Bill Gates patient the PC? — Preceding unsigned comment added by Saberinmypants ( talk • contribs) 19:11, 30 December 2015 (UTC)
Referring to this question and another one that this question refers to, I selected two of the three updates just now (when I posted the question, before it was deleted without justification). Okay, now there are four. The first two have finished downloading but I haven't restarted the computer since then. We will see what happens. Anyway, I still had to do a startup repair on Sunday and don't know why since I never get specific messages about what happened. Tuesday, everything was fine. If everything works Thursday, I will download the other two, maybe one Thursday and one Friday, later this week.
And to satisfy the IP who had no right to delete this, I'm still trying to document what is going on or get answers. I'm not supposed to edit archives.— Vchimpanzee • talk • contributions • 17:12, 29 December 2015 (UTC)
A possible clue to what might be going on is this. I got a message that an update failed. I should have made a note of the error message before telling it to try again. Anyway, it started at 37 percent. I don't know whether it is all right to continue downloading or whether I should just start over. I've had downloads stop in the middle. It's probably my slow Internet but I'm reluctant to upgrade.
Here's the information in my update history (oh, good, it includes an error message):
System Update Readiness Tool for Windows Vista for x64-based systems (KB947821) [October 2014]
Installation date: 12/31/2015 11:44 AM
Installation status: Failed
Error details: Code 80072EFE
Update type: Important
This tool is being offered because an inconsistency was found in the Windows servicing store which may prevent the successful installation of future updates, service packs, and software. This tool checks your computer for such inconsistencies and tries to resolve issues if found.
More information: http://support.microsoft.com/kb/947821
Help and Support: http://support.microsoft.com
It's at 43 percent now. The description of this update suggests it might fix the other problem. — Vchimpanzee • talk • contributions • 16:55, 31 December 2015 (UTC)
No, I tried that with TiVo; it was fortunate I was having modem problems, which would have gone away if I had just plugged the thing in right. They decided the modem had gone bad and sent me a new one, so I have WiFi for the TiVo if I want it. But this computer has a cable. Instead of a percentage I now see "Installing update 1 of 1". When I go to the update history it says "failed" three times for the cumulative security update and five times for the system update readiness tool. This must refer to all the interruptions. I have a theory the interruptions might result from my trying to do other stuff at the same time as the downloads. But I have no place else to go. If the college library was open I could use the Internet or look at actual newspapers while downloading or doing the virus scan, so I won't slow down everything else.— Vchimpanzee • talk • contributions • 20:51, 31 December 2015 (UTC)
Can anyone explain to me what happened today? First, let me say the person from the Microsoft site gave up and referred me to the paid support service. There may be no point. I've never had this much trouble getting started. Two blue screens, one time everything froze, and one time the screen just went black. The last one came just after a message McAfee scanner quit working. It wasn't the "service host" like it usually is. All is well now, I guess. The first blue screen came with a message IRL_NOT_LESS_THAN_OR_EQ, or something like that. Then when I restarted, before I even got to where I could get on the Internet, ther were all these identical lines across part of the screen which appeared to be scrolling really fast but as if they were credits from 1950s TV series, not affecting what was in the background, except the word "Welcome" and the circle that is supposed to be turning round and round are stopped. I had to unplug the computer to restart it. Then came one more blue screen (which came first, that or the McAfee message which was followed by the screen going black, doesn't really matter). The message was PRN_LIST_CORRUPT. Maybe. PRN is a group of radio stations airing NASCAR. Anyway, I'm wondering if this is even something I can recover from. Even if I take the whole thing to the store, how much longer will the computer last? Is the expense worth it? I don't like unplugging the monitor because I was unable to plug it back in when I got a new one, broke the cable, and had to replace that, and I made sure the person at the store plugged it into the computer. With a new computer I know I have to go through it, so I hope I do it right.— Vchimpanzee • talk • contributions • 18:49, 3 January 2016 (UTC)
