  1. yeah, eastern suburbs on Wireless Internet In An Off-Grid House · · Score: 2

    OC, Pomona, San Bernardino, Riverside, etc. Around here even rather poor people often have a window air conditioner that they use now and then, when they can afford to. Anyone middle-class or richer will have A/C on all the time.

    Of course if I lived by the seaside I might not need A/C as much. =]

  2. GCC doesn't translate to C on Is FORTRAN Still Kicking? · · Score: 2

    GCC now has a very flexible front-end and back-end model. The front-ends translate the language into an internal sort of meta-language, and the back-ends output assembler. Even C code goes through this translation process, via the C front-end to GCC.

    Besides, even if it did translate to C, it could still be faster than most C code, as it'd likely be translating to a subset of C.

  3. do you live there? on Wireless Internet In An Off-Grid House · · Score: 2

    I've lived here for a few years, and absolutely every single person I know has air conditioning in their homes. Those with new (less than 15 years old or so) homes have central A/C, and those with old homes mostly have window A/C units (usually in the bedrooms), though a few have retrofitted their houses with central A/C as well. I seriously don't know a single person in the L.A. area without A/C. Perhaps if you're talking about the low-income areas people don't have A/C because they can't afford it, but I haven't heard of people voluntarily not having A/C.

  4. where in California do you live? on Wireless Internet In An Off-Grid House · · Score: 2

    In the L.A. area, nearly everyone has air conditioning. And business/offices have ridiculously powerful air conditioning units -- it's not uncommon to have the place at 72 F on a 95 F day.

    Simply making all businesses turn their 72 F thermostat up to 78 F would likely save more power than everyone in the entire country switching to "low-power" computers.

  5. that doesn't mean you use over 300 watts on Wireless Internet In An Off-Grid House · · Score: 2

    Unless you buy expensive brand-name (and well-tested) power supplies, with quality components, your average computer power supply will have a high rate of failure if you use even 70% of its rated power for any extended period of time. The 300 W figure is generally the maximum peak power it can spike to, not the maximum power it can sustain for any length of time (i.e. more than maybe 500 milliseconds). So if you blew it out, it just means that you spiked momentarily above 300 W once (or if it was a cheap generic one, maybe even 280 W). It certainly doesn't mean that you sustain over 300 W of power consumption.

  6. it's not an arid climate, by a long shot on Wireless Internet In An Off-Grid House · · Score: 2

    Did you not read the post? Houston in the summer is often 80-90% humidity, with rain every other day (checking weather.com, it's currently 84% humidity, at 2am, despite not having rained in 2 days). It's about as far from an arid climate as you can get without traveling to a rainforest. Condensation is a huge problem, even without a radiant cooling unit. Leaving a glass of ice water on the counter will quickly get you a very large pile of water. I don't see how evaporative cooling could work at all, when the air is so saturated with water vapor that evaporation is an extremely slow process. Certainly it wouldn't be enough to cool a house from 100 down to 80 or so while it's being hit by sunlight.

  7. and that's why it's not feasible on Wireless Internet In An Off-Grid House · · Score: 2

    Well, it might be feasible in cooler climates, or if you really don't mind no A/C. But if you live in say Houston, TX, where the summer is usually 95-100 F and 80-90% humidity, evaporative cooling is not going to cut it.

  8. computers take very little power on Wireless Internet In An Off-Grid House · · Score: 5, Informative

    You mention 150 watts as if it's a large number.

    Some rough figures:

    Room with 3 incandescent lightbulbs: ~180 watts
    32" television: ~250 watts
    Microwave: 1000-1500 watts
    Stove: ~2000 watts
    Oven: ~3000+ watts
    Window A/C unit: 750-1250 watts
    Central A/C for a 2000 sq. foot house: ~5000 watts
    Central A/C for a 4000 sq. foot house: ~9000 watts

    So running your computer 24 hours a day would take approximately as much power as running your central A/C for maybe 20-30 mins/day. If you live in a hot climate, raising the temperature on your thermostat by 1 or 2 degrees is going to save you more power than getting rid of the computer entirely. And certainly much more than shaving 20-50 watts off your computer's power usage by using "low-power" components.

  9. it's 4-year-old somethingawful.com jargon on NeoNapster's NeoAudio Rips Off CDex · · Score: 2

    I'm unsure why 1998-99 somethingawful.com gimmicks are making a resurgence on the internet. Maybe a bunch of people just discovered the site or something. "YUO = TEH SUKC" is another SA gimmick making a resurgence. It's all a bit annoying.

  10. This is why you don't tell them on WarTalking Arrest · · Score: 2

    You just happily use their network for free access until they figure it out themselves.

  11. Re:Did the author get paid? on Think Python · · Score: 2

    Does anyone know if the author of the book gets paid by Green Tea for donating or "copylefting" the book?

    It probably doesn't make any difference either way, since the author owns Green Tea.

  12. that makes it even worse on DJs Spinning Those Hard Drives · · Score: 2

    FM radio and MP3 encoding both degrade audio quality, but do it in different ways. So if you play an MP3 over FM radio, you don't get the worse of the two qualities (which would be normal FM radio quality, as you seem to assume), but you get in effect quality that's degraded by the sum of each separate degradation. So it sounds terrible.

    As a simple example you can try at home, take a CD and encode it to a 128 kbps mp3. Then decode that mp3 back to WAV, and encode it to a 128 kbps mp3 again, using a different codec. Your re-encoded 128 kbps mp3 will sound terrible compared even to the original 128 kbps mp3.

  13. I hope they use some high-quality encoding on DJs Spinning Those Hard Drives · · Score: 5, Funny

    I'd hate to walk into a club with a nice sound system and hear it pumping a 128 kbps mp3 encoded with Xing.

  14. yeah on AOL Won't Enable Instant Messaging Interoperability · · Score: 2

    Because I don't really see an advantage to any of the other networks. In fact, apart from the open aspect, I see mainly disadvantages, since AIM's uptime and stability beats everyone else's by a longshot (I don't think there's been AIM downtime longer than 15 seconds since sometime around early 2000).

  15. You can still get citizenship on 235,000 Software Engineers Can't Be Wrong, Right? · · Score: 2

    The main purpose of permanent residency status is to allow someone to live and work in the U.S. without fear of being deported on a whim (such as losing your job on an H1B visa, for example). If someone wants to, they can get U.S. citizenship -- but that requires a committment to be a full-fledged American. Often giving up one's birth citizenship is encouraged (though not often actually required), since it's hard to be a full-fledged American if you still consider yourself a citizen of a foreign country. Not everyone wants to make that committment, and permanent residency status allows those who don't to avoid it while still enjoying 80% or so of the benefits of citizenship.

  16. I hadn't heard it much on Princeton Hacks Yale, Harvard Not Surprised · · Score: 2

    I'm not going to claim it wasn't used at all in the original usage, but during the 1980s I primarily heard it used to describe unauthorized access to computer systems. This wasn't just by the media (which didn't use it all at until the mid-to-late 1980s when it became a major issue), but by the majority of people who frequented BBSs and local computer clubs.

  17. why use Trillian? on AOL Won't Enable Instant Messaging Interoperability · · Score: 2

    I used Trillian for a while. It was pointless -- the only protocol it supported I ever used was AIM. And the official AIM client is nicer, so I use it instead.

    I don't know a single person who doesn't have AIM, so there's no reason for me to use anything else.

  18. AppleScript doesn't do what he wants on Automatic Functional Testing for Mac and Linux? · · Score: 2

    AppleScript interfaces directly with the program at a lower level than the GUI -- it's essentially an alternate method of controlling the app, plugging into the same API as the GUI widgets do. This tests the app and everything below that, but it's not exactly the same as actually testing through the GUI itself, since you're bypassing it.

  19. technically, that's correct on Princeton Hacks Yale, Harvard Not Surprised · · Score: 2

    But for the past 20-25 years it's been primarily used to refer to unauthorized use of computer systems. Only in the past 5 or so years have some people been trying to resurrect the original (long since obsolete) usage, which is about as likely to be successful as convincing people that "gay" merely means "happy" and has nothing to do with homosexuality.

  20. Tomorrow in the mail on Red Hat Asks for UCITA Reversal · · Score: 5, Funny

    Dear Red Hat,

    We have received your letter dated 29 July 2002 requesting that we rescind the UCITA regulations. Rest assured that we have been completely unaware of the deleterious impact these regulations might have on open source software; had we known we would never have adopted them at all. The Commissioners apologize for any inconvenience this has caused, and will now move to reverse UCITA's adoption immediately. Thank you for bringing these issues to our attention, and please don't hesitate to contact us again if you have any further concerns.

    Sincerely,
    The National Conference of Commissioners on Uniform State Laws

  21. Which one is progress? on First Wind-up Phone Charger Review · · Score: 2

    First they were telling us that moving from hand-cranked coffee grinders to electric coffee grinders was progress. Now they're telling us that moving from electric cell phone chargers to hand-cranked cell phones chargers is progress.

    So are hand-cranks "old-fashioned" or are they "innovative"? Technology is so confusing these days.

  22. Winamp support is crucial on Real Will Include Ogg Vorbis Support · · Score: 2

    The fact that it's included in Winamp now is I think one of the most important factors for Ogg's adoption. I used to encode only in mp3, because when I sent files to a non-computer-literate friend, it'd be a pain in the ass to also send the Ogg plugin, explain how to install it, all the while being asked why my files can't be played by default Winamp like normal MP3s can be, etc. Now if I send an Ogg and they can't play it, I just say "your version of Winamp is too old; upgrade to the newest one," which is a concept even the most tech-illiterate person understands.

  23. Oggs on Real Will Include Ogg Vorbis Support · · Score: 2

    The format is Ogg. Vorbis is just the codec. So if you have multiple Ogg files, you have Oggs. Just like if you have multiple LAME-encoded MP3s, you have MP3s.

  24. Not with the uptime we get around here... on Time to Say Thanks For the Uptime · · Score: 2

    Time to Say Thanks For the Uptime

    If the purpose of this holiday is to thank the sysadmins for our fabulous uptime, I think I can safely skip it.

  25. sounds like it could be challenged on Open Source, Real Media Mega-player? · · Score: 2

    If it is in effect nothing more than patenting a file format, that sounds like it could be fairly easily challenged in court if someone had the money and time to do so. Patenting a file format is just the computer equivalent of patenting a particular layout of an encyclopedia -- it's one particular scheme for arranging information.
