As I recall from the couple OLPC mailing lists that I read, they did (and continue to do?) a lot of LCD and overall 'destructive' testing. The LCD was sourced very carefully can contains a special UV filter, in fact last I heard there was a 'desert' and 'not desert' version of that to deal with the different environments. Similarly, they've done a lot of battery testing and there are improvements that will go into the revised and more final hardware.
The OLPC does not contain any real moving parts (hard disk, etc) and the motherboard is behind the LCD panel, not under the keyboard (where the battery is). The processor runs nice and cool (in fact, it's underclocked).
I worked at one for a while and it was a welcome relief from my 'burn your lap' ThinkPad with a PIII : ) That said, proper suspect and power management isn't done yet, so they have a lot more to do in these areas.
potential security problems, for one thing. You should not trust 'binary blob' drivers with your kernel-space, right? you can't inspect the source code...
The 'blob' song actually explains it really well, I think:
Seriously, if it can do USB host, then I am sold. It can then be a hand-held oscilloscope, handy terminal (via USB->RS232 adapter) for embedded devices, etc.
most spam I get now looks to be from botnets rigged up using people's PCs here in the United States. Very little (in my inbox anyway) comes from the usual suspect geographical areas.
We have that now, it's just that we type 'sudo' rather than pushing a big red button, but it's the same effect. For you, perhaps we can wire up a red button that echoes 'sudo' to your shell?
The current doesn't matter here: your device will draw as much as it needs (up to 0.5A for a USB device), not as much as the car 'supplies'. The problem is that it needs to be at 5.0V or so, not 12V. Also a typical car's '12V' supply is (ideally) more like 13.8V or so because the alternator charges the battery as the engine runs. That '12V' in a car is also very nasty for devices that don't do a lot of regulation: big spikes, etc.
Want your own USB charger port in your car? Grab or build a good DC/DC converter for ~12V->5V with some filtering and spike suppression (as 12V zener diode should do), connect it to the same circuit as the 12V cigar lighter plug, and run its 5V output to a USB connector pigtail (just cut up a spare USB cable, the wires are color coded, ie: red and black). It's not particularly difficult to do.
I'm not fond of the standard-issue GTK C API but gtkmm provides a nice wrapper for C++ and, with Glade, it can be pretty painless to build GTK applications. pygtk is also very nice.
The trouble with rulers and other real-world dimention stuff (for printing) in web applications seems to be that the CSS features (http://www.w3schools.com/css/css_ref_print.asp) that handle them are not supported in the majoy browsers. The web application has, thus, little to no control over how the document will be printed and how dimentions, page breaks, and margins will be handled. I assume that, for those reasons, there's no point in including a ruler or the like. Hopefully this will change in the future.
A friend of mine received a single-quantity SMT chip sample from Analog in about a 4"x1" box, overnighted from Singapore. It beat my National chip sample, which came in a padded envelope that had tread marks from when the UPS truck had run over it. The reasonable samples they seem to send are the ones digikey distributes, where they put the chip, a ton of really clever padding, and a nice brochure into the standard digikey 'small' box. 'seems like a huge waste but it's not as bad as what they do in-house.
That said, many microcontrollers and processors now are designed to execute Java bytecode in hardware (for example, a version of the ARM926 can do it).
actually, all of the experts-exchange pages that I've seen come up do have the answer, you just need to hold page-down to scroll past all the crap. they just look like they require a subscription but they don't seem to.
I don't see a third-party candidate that I would want in office. I don't like either of these guys, but I don't want to do 'lesser of two evils' this time around. I think I will just not vote, as noone on the ballot that I've heard of thus far sounds like a good candidate. If someone had a good 3rd party one, I would go for it. When the democrats and republicans see the 3rd party percentages rising, it will send a message and they will hopefully pick better candidates 4 years from now.
Similarly, the copyright thing isn't going to swing my vote one way or another (or have any other influence) since both of those idiots are equally guitly.
Dell support for home / home offic eusers is beyond terrible. However I had to call their support for server products once. What happened was a RAID controller (PCI card by Adaptec) failed in a fairly basic PowerEdge. I called at some weird hour but I quickly got a guy with a chinese-english accent (Hong Kong?) who spoke very clearly, got the troubleshooting info together, went through it, and then got me a case number for the replacement part they were to sent (and expedited it as I needed it ASAP). The new card arrived in about a day and a half and that was that.
Now if you call about a Dimention or something... then it's a complete disaster.

I think that they could be doing something more useful with the Bad Vista campaign, namely I think this guy's post sums things up:

Well, huntung for mushrooms is a pretty normal activity in Russia.

If they're to 'learn' this stuff, have them do a few lectures on 'fair use' as well
from the article:
"Within the company, less than 10 people... We do have, obviously, a lot more attorneys than that, who are focused on SCOsource."
Sounds like a plan!

hey, it's all about subverting the dominant paradigm
'i' stands for fuel injection, so what would they do for diesels, like the 330d? Or the Motorsport cars, etc...
they have room but this flight will be just the pilot. later thay will carry the 3 people needed for a prize attempt.
right, they're just focusing on their main business model (frivolous law suits)
and how about some jail time for extorsion, etc?
