If you want to reduce power usage, would you want to use an Intel x86 chip in that goal? Wouldn't a PPC Linux be more power efficient?
I doubt it, they are using a 16MHz 386 for this. That probably uses less than 400mW and runs cool to the touch without a heatsink. Something based on a MIPS/ARM/PPC core would provide a lot more MIPS/Watt though.
I wasn't involved from a customer perspective, the company I work for does hardware design/development and manufacturing for Envenergy and did some prototyping for Enflex. Sharing an opinion on which company has a better system may put me in an uncomfortable position here at work.
Both are embedded linux systems for building automation, power consumtion monitoring, and providing information about the monitored systems over the internet.
A PIC16F877 doesn't have the power to decode OGG or MP3. They use a hardware decoder in the SliMP3 to do the actual decoding, the pic just handles the networking and display.
Also, I wouldn't exactly call a 20MHz 8-bit microcontroller "fancy".
You'll want to replace that extension cord with, hmm, maybe a car battery and jumper cables? AC from an extension cord won't get your electrolysis very far.
The last time I was in traffic survival school (I can't help it that all the speed limits are 20 MPH below what they shold be;), the teacher mentioned this situation specifically. In Arizona, in controlled intersections without a left turn arrow, when there is too much oncoming traffic to turn, the correct thing to do is to pull into the intersection and wait for the light to turn yellow. When oncoming traffic stops you can make your turn. To wait behind the line means you'll never get to turn.
Have you got any examples of production vehicles that have drive-by-wire controls for anything other than the throttle and transmission? The article that you pointed to only mentioned throttle control in current vehicles.
Agreed, and in addition most linux drivers are portable between different architectures. Since all those windows drivers are only compiled for x86 they wouldn't do anything for people running linux on alpha, ppc, sparc, arm, etc...
Notice that I said the essay looked as though it was filtered through a 14 year old on an IM. I think that Prince wrote a very well thought out and insightful (and far more grammaticly correct than I could manage) article that was seriously marred by his shorthand. It's like having yellow text on a white background - pointless and distracting.
I actually haven't heard of any car put into production that had servos operating the steering or brakes. AFAIK they all still have mechanical linkages from the steering wheel the the front wheels (albeit with hydraulic or electric power assist) and the brake pedal still directly operates the brake master cylinder (again with power assist provided by a vacuum or electric solenoid, and servo controlled hydraulics for ABS and traction/stability control). There are several cars out now that have a drive-by-wire throttle, and most automatic transmissions are electronicaly controlled, but virtually all cars on the road can still be brought to a safe stop in the event of a massive electronic failure.
I think I'd be a lot more interested in the girls that are impressed by the MP3 player that I put into my car than the girls that get impressed by a tan (not to mention that I go straight from fish-belly white to beet red after 15 minutes of solar exposure).
How do you figure 20KW is more than a vehicle can easily produce? That converts to about 27 horsepower, even with a horribly inefficient generator on a PTO a humvee should easily manage that.
Heh, it seems Nevada officials would like to leave the bad 'ol days of nuclear testing behind them and focus instead on their illustrious(sp?) history of gambling, prostitution, and racketeering;-)
Well first of all, its convenient that you left out definition a from www.m-w.com which is exactly the same as the first one from dictionary.com. Secondly, from a legal standpoint, copyrighted materials aren't even property. They are works for which the government has granted someone an exclusive liscense to control the distribution of the work for a limited period of time. Insisting that copyright infringment is "theft" is just a convenient way to distract people from the real nature of the crime.
\Theft\, n. [OE. thefte, AS. [thorn]i['e]f[eth]e, [thorn][=y]f[eth]e, [thorn]e['o]f[eth]e. See Thief.] 1. (Law) The act of stealing; specifically, the felonious taking and removing of personal property, with an intent to deprive the rightful owner of the same; larceny.
Note: To constitute theft there must be a taking without the owner's consent, and it must be unlawful or felonious; every part of the property stolen must be removed, however slightly, from its former position; and it must be, at least momentarily, in the complete possession of the thief. See Larceny, and the Note under Robbery.
The US Government does not "own and operate the internet". It started the predecessor to the internet with arpanet but no single entity owns or independantly operates the internet, AFAIK most of it is owned/operated by telecom companies and universities.
I discovered the power of Frank, Patsy, Dean, Hank, Sammy, Tony and Bing about twelve years ago, and life's been groovy ever since. Do you know any radio stations where I can hear *that* 24/7? I didn't think so.
FYI, while that sounds about like the seventh level of hell to me, I recall an article on salon.com about Clear Channel that metioned one of their higher ups would like to create a station exctly as you describe and call it "Vegas Radio".
Yeah I get it now, but it was a seriously lame joke considering that: 1) Emulator inside an emulator jokes are done every time an emulator gets mentioned on/. 2) There is already a Gameboy emulator that runs natively on the Zaurus.

Radio Shack has one here
I've already worked with two companies doing almost exactly the same thing.Check these out:

You only play games with your pc? You don't, for example, post to slashdot with it?
Is that an imperial shitload or a metric shitload?

Ever seen a Cox Teedee .010? These little suckers can hit 30K rpm and I'm sure they're smaller than this car ( that picture includes the gas tank).

It looks as though the entire essay was filtered through a 14 year old girl chatting on an IM. It's almost painful.

Shouldn't that be "THEY MADE DUPLICATES OF MY ELECTRONS!!!"?
And some stuff for the lamness filter.

Try reading that again, this is a Palm handheld emulator, for running PalmOS, Gameboy has nothing to do with it.
