| brolin_empey | Is it expected that a fan in a stationary computer in my office sounds much louder than usual when the temperature in my office reaches 30°C? Or is it just coincidental that the temperature is this high when the fan sounds louder than usual? | 03:38 |
|---|---|---|
| brolin_empey | If the loud fan is on the video card with a fan, which may be the only video card in the office that has a fan, then I should replace the fanful video card with a fanless video card. I bought this video card in 2008; since then I switched to buying only fanless video cards. This fanful video card may still be the only nVidia Quadro video card we have, though. | 03:42 |
| brolin_empey | I guess I should ask in ##hardware instead of here but that channel moves too quickly and they discuss current x86 hardware of little interest to me because I still use Core 2 era and older x86 computers. Well, the current x86 hardware is still of some interest to me but I probably would not have it until it is multiple years old because it depreciates too quickly to buy when it is new. | 03:45 |
| Oksana | DocScrutinizer05: I try this in Firefox, Alt+D focuses on AddrBox, Shift+Tab,Tab focuses on Tab, but Shift+Ctrl+PageDown does nothing | 04:27 |
| Oksana | And when I try out different combinations, like Ctrl+Shift+PageDown, or PageDown+Ctrl+Shift, I get tab scrolling or something | 04:29 |
| brolin_empey | Is there an x86 motherboard with a proper hardware design that stores the configuration of the motherboard firmware in non-volatile memory instead of in volatile memory powered by the cell/battery that powers the clock? After the mains power to my office was down for around a minute tonight, I had to replace the CR2032 cell/battery on a Socket-T (Core 2 era) microATX motherboard; I had forgotten that the computer user has to manually reconfigure the | 07:19 |
| brolin_empey | motherboard firmware after replacing the cell/battery on the motherboard because of the lame hardware design, which is presumably for historical inclusive-or cost-saving reasons. | 07:19 |
| brolin_empey | Socket T AKA LGA775. | 07:20 |
| brolin_empey | I realise that I can use a DOS or Linux or maybe Windows (?) program to back up and restore the contents of the so-called CMOS memory but this should not be necessary because the motherboard configuration should be stored in non-volatile memory in the first place. | 07:24 |
| brolin_empey | motherboard firmware configuration, whatever. | 07:25 |
| brolin_empey | I guess expecting things to be done elegantly and using an x86 computer is ironic, haha. | 07:26 |
| brolin_empey | I guess oldschool switches on the motherboard can be considered a form of non-volatile memory, heh. | 07:30 |
| brolin_empey | switches, jumpers, whatever. | 07:30 |
| luke-jr | why x86? | 07:34 |
| brolin_empey | I guess that you would need a reliable way to clear the contents of the non-volatile memory on the motherboard even if the computer cannot boot to prevent a chicken or egg problem if the chosen configuration prevents the computer from booting. | 07:35 |
| brolin_empey | luke-jr: Because we need to run closed-source software built for x86 on Windows? Microsoft discontinued Windows NT for Power, specifically the PowerPC Reference Platform (PReP) but not Power Macintosh platform in NT 4. | 07:39 |
| brolin_empey | Microsoft kept releasing service packs for NT 4 after the PowerPC and MIPS ports of NT 4 were discontinued so NT 4 on Power or ISA is not even the current version of NT 4. | 07:44 |
| brolin_empey | I mean on Power or MIPS. | 07:45 |
| luke-jr | lol windows | 07:52 |
| inz | brolin_empey, yeah, reliable reset is a "nice to have(tm)", and also since you want the RTC to keep running, you need a battery anyway | 07:56 |
| brolin_empey | inz: More generally, you need constant power, which these days can be supplied by a supercapacitor instead of a battery. | 08:06 |
| brolin_empey | luke-jr: Dave Cutler is my hero. ;-) | 08:08 |
| luke-jr | what is that | 08:11 |
| brolin_empey | I wonder if an x86-64 CPU could switch directly between long mode and virtual 8086 mode if x86-64 had been created by Intel instead of AMD. | 08:11 |
| brolin_empey | I mean I wonder if Intel would have designed that part differently for better backward compatibility than how AMD designed it. | 08:12 |
| brolin_empey | luke-jr: What is what? A supercapacitor? Dave Cutler is the head architect of Windows NT. | 08:14 |
| brolin_empey | Well, he was in the early days, maybe no longer is. | 08:28 |
| brolin_empey | early years. | 08:29 |
| brolin_empey | Today I discovered the PicoPSU series. | 15:01 |
| inz | now I did, too! | 15:14 |
| DocScrutinizer05 | hmm, well. 12V in -> [ATX PC] out | 17:25 |
| DocScrutinizer05 | might be very useful for poor man's "USV" straight from 12V LA car battery on a charger | 17:25 |
| sicelo | i've had two PicoPSU's for a while, from some old i386 VIA boards | 21:28 |
| slobber | what does the majority use for maps on n900? i found mappero but i'm unclear of its development state http://www.mardy.it/mappero/ | 22:27 |
| brolin_empey | N900 is a model of computer, not a software platform. | 22:30 |
| slobber | what | 22:31 |
| brolin_empey | Presumably you mean Maemo but Maemo is not the only OS available for the N900. | 22:32 |
| slobber | yes, on maemo | 22:32 |
| sicelo | i still use Ovi Maps but i think Modrana is a better choice for most | 23:15 |
| sicelo | if you go for modrana, use the versions on github | 23:16 |
| slobber | thanks sicelo | 23:33 |
