I don't know which Nokia charger you have, but mine (ACP-12U) is 5.7V, 800mA. That's a bit over 4.5 watts.
I bet some winmo phones run at > 4 watts standby;-)
For an intel chipset mobo, 4 watts is great. I'm hoping Soekris will come out with something atom-based. A good networking-focused board with that CPU would rock. Not that I'm complaining about the CPU power of my net5501. I just wish there was a good multi-gige network board out there.
Sorry, I had the aspect wrong. PC monitors are not 16:9, they're 16:10. (this still shows there is a 9% difference in DPI between the 2 screens)
I guess I should have used the Samsung 2243BXW 22" screen.
It's $310, which is 19% more for 34% more resolution. The 22" has the same 90dpi as the 19" screen. You still get more for your money with the widescreen. Just not as much as my first post made it out to be.
Basically your argument is still bunk. You don't get less for your money going with widescreen..
That's why a lot of places have a backwards attitude to promotion. You shouldn't get promoted to do something new. You should get promoted because of what you're doing now.
MTBF means a LOT to people with large disk arrays. Think about having a cluster of 1000 machines with 2 drives each. That's 2000 drives. If the MTBF is 750,000 hours (seagate specs for SATA drives) that's a broken drive every 15 days on average.
Exactly, My job is running high performance computing clusters. You don't need to put much effort into your cluster distribution at all. As long as it's stable, and gets the job done, why mess with it.
The things I (and my co-workers) put a lot of optimization effort into is the kernel and our apps. You're exactly right.. 99.9% of our CPU cycles go into getting work done, and that 0.1% used by/bin/ls don't matter a bit.
Most high-speed trains are electric.. All you have to do is cut power to the line and have an automatic "power gone for too long? apply brakes" control into the train's automation. (yes, there is a bit of backup power on the train)
Yup, I love my X series. I've been carrying thinkpads everywhere with me since 1996. I started with a Thinkpad 500. Then a T20, and then decided that size was more important and have had several of the X series since then.
As for backups/mailing, I agree with the other posts. SD cards are the way to go, not optical.
One other cool option would be an OLPC if you can get your hands on one.. although the keyboard is sub-optimal for a lot of writing. Same thing with the Eee PC, just not enough quality in the keyboard. The OLPC does have the more waterproof advantage. It also has a daylight readable screen. I wish more laptops had direct-sun readable screens.
I also suggest a good case. Waterfield Designs makes a bunch of really good custom-fit cases for various laptop sizes. A bit pricey, but damn good quality. http://www.sfbags.com/
This is why I apply replay gain tags to my FLAC files. It lowers the maximum volume of loud tracks, and bumps the volume slightly for quiet tracks. The gain tags added are both per track and per album and get applied in album mode when playing in order, and track mode when in shuffle.
Since my playback is through Slimdevices volume correction and DAC processing is done in 24 bits so there is no dynamic range loss or clipping.
Highly compressed music is making "the most" of the bits that are there. They pack a LOT more into the bit space provided by the format.
The big thing that I'm hoping kills off some of the loudness wars is the "replay gain" feature that most good flac/mp3 players can use. This will mute the extra-loud albums slightly, and bump the quiet ones slightly reducing the ability for the industry to game the format.
No, that was not my assertion. My assertion is that you still need the lower bits for ALL music. Having more bits doesn't increase the maximum volume, it increases the fidelity of the recording. If CDs were 24bit, the dynamic range compression tricks that mastering people use to make really really loud CDs wouldn't have to hurt the quality of the music so much.
The mastering process uses dynamic range compression and software to do soft clipping of extra loud bits.
That's not how bit depth is used in audio recording/playback.
Bits in audio are all about dynamic range.. you still need all the bits for loud music as well as quiet music.
16 bits gives you 96 dB, and 24 bits gives you 144 dB. This is why 16bit is "good enough" for most music, but recording is almost always done at 24 bits to allow for more accuracy of level adjustments and mixing. Then down-mixed to 16 bits.

Thanks for the great post.. It makes me wish I had spent more time in EE classes instead of becoming a sysadmin. It's one of those things that is interesting about how education changes our culture. Back in the day everyone studied analog electronics for EE, lots of people understood how it worked. Today there are still people who are good with analog, but the vast majority are doing digital systems. This shift in brain share has reduced the quantity of people improving the understanding and measurement of audio systems. Anyone who likes analog is probably doing more with high-end RF design for wifi and such because it probably pays better than doing audio.
For windows, you should enable ACPI suspend to memory.. this would provide an instant-on function, while saving 90% of the power while sleeping. You could even enable it so she doesn't have to do anything but walk up to the computer and hit the keyboard.
I've got 2 computers at home right now, one that is a 24/7 server (mythtv, slimserver, big raid storage), and a shuttle desktop PC. I upgraded the server a few months ago from a dual athlon 1600+ to a dual core X2. This let me ditch 5 PCI cards, and one CPU socket. It also let me enable CPU clock ramping. This reduced the power usage of the machine from ~200W to 130W. Pretty good for a machine with 5 SATA drives, and a decent PCIe video card. Recently I've been thinking about buying a nice long 30' DVI cable and some USB repeater stuff to extend the console from the basement to my office on the first floor. This would let me eliminate the desktop PC entirely. I just wish Cat5 KVM extenders were cheaper. Best I've seen is around $500-600 for a gefen DVI/usb extender
WTF are you talking about. I don't think Google sends your information to advertisers. Sure they do keyword matching to give you ads that make sense... but no part of that is "sending that info to advertisers."
Automatic faucets are generally used for 2 reasons:
sanitary: You don't have to put dirty hands on a handle and then back on the dirty handle after you clean them.
water conservation: Some people can't be bothered to properly turn off a faucet. Sad but true.
On topic: I think this is a great idea, and really needs to be added to a lot more devices. I still think it would be better to activate the relay via the power generated by the return of the video signal to the display device, rather than via a small solar cell and capacitor. You could still use some capacitor to charge the power to activate the relay. May take a second or two to charge.

How do you know that 3261 files is actually not just ~16 images per person in their profile?

You don't compare the diagonal measurement when comparing screens. You compare price, resolution, and pixel pitch.
Let's compare 2 screens that have similar specs
Samsung 943BX, 19" 1280x1024 $260 (newegg) 4:3
Samsung 2043BXW 20" 1680x1050 $270 (newegg) 16:9
These are 2 very similar screens in terms of performance specs. Both are 5ms, have the same inputs, and have a pixel pitch within 5% of each other.
For 4% more money, I get 34% more resolution.

MTBF means a LOT to people with large disk arrays. Think about having a cluster of 1000 machines with 2 drives each. That's 2000 drives. If the MTBF is 750,000 hours (seagate specs for SATA drives) that's a broken drive every 15 days on average.
MTBF is NOT calculated for a single drive. MTBF is calculated based on an average for ANY pool size of drives.
If you have 10,000 drives, and the failure is 1 in 1,000,000 hours, you will have a failure every 100 hours.
Here's a good document on disk failure information:

Yes, especially when most of Ford's transmissions are made by mazda.
There are no local car companies anymore. Almost every single one of them that produces any quantity is a global venture.

You'd like the Squeezebox then. No DRM supported.
