Lots of moisture is a problem simply because it promotes corrosion.
Yes, some of the metallic pouches are indeed intended to act as cages. There is more than one kind metallic pouch in use. Some only have metal on the outside layer, others integrate it into the plastic and do let it come into contact with the device.
Okay, found a link to a detailed explanation here. My god, there's such a thing as an ESD Journal? And I thought that reading Slashdot was bad enough.
The static problem isn't mythical or anything, but chips attached to boards do stand a a better chance of surviving than bare ones. Simply, there's all that extra metal to take the hit.
Someone else mentioned that too much moisture can be a bad thing, but so can too dry an environment (static likes to come out and play then).
Someone mentioned the pink pouches. Those usually just have an antistatic coating (same idea as the antistatic clothing sprays and furniture polishes). They aren't intended to be conductive or anything like that.
The metalic pouches are supposed to act as a shield or cage around the components inside. These cost more, that's why cheap components aren't packed in them.
It's probably plain old fashioned competition. Apple does have its own answer to PowerPoint in Keynote, and still sells AppleWorks which might not be an Office killer, but still holds its own against OpenOffice.
OS X also differs from the other Unix-like platforms in that it has a native Office port, so there really isn't an urgent need to produce an substitute.
Ethylene glycol (plain old antifreeze) will keep the critters from growing, but you need to make sure your plumbing, pumps and seals are compatible. Leaks are a bit of concern because, of course, that stuff is poisonous. It's really not something one would want in, say, an environment with pets; cats in particular tend to be attracted to the sweet taste.
DI-based filtration systems can work really well too, but that would be overkill for the amount of cooling a small computer application would need. It's effective but the materials do need periodic replacement.
As Microsoft is so fond of pointing out Unix sysadmins get paid more then Windows sysadmins. Why educate your kids to get lower paid positions?
There aren't a heck of a lot of system administration courses in the K12 offerings. On the other hand, I don't see much evidence that writing or arithmetic are being taught any more either, so maybe IT grunt training would be better than nothing.
Not really. 2.2 and up get a little closer to that, but Python is really a procedural language with a very nice but very optional set of OO features. (Internally, the Python and Perl OO implementaions are very similar, even if Perl's hideous object syntax does a good job of hiding it.) This is a nice pragmatic approach, akin to what Objective C does.
If OO purity is one of those things that appeals to you, Ruby or Smalltalk might be fun toys.
We have a fair amount of locally produced electricity in Massachusetts, at least in some of the old mill towns. Yeah, we get the occasional small outage, but we're mostly isolated from these regional thingies (the folks at the plant are really good about watching out for these messes and taking us off the grid).
See, there's that *thing* again, this assertion that the Sequent techniques were trade secrets. These techniques were patented. Patented techniques aren't trade secrets, by definition.
These are basically iPAQs with no case or display. I've no idea if they'll be able to meet your price range, but it can't hurt to ask: http://www.applieddata.net
There is a thingy on the market now that almost does the same thing as your HP knob, called the Griffin Powermate. It's a wee bit expensive for what it does, but any device with a programmable blue LED can't be all bad.
Flamewars were minimal, people were respectful, and knowledge flowed freely.
I thought for sure that this old chestnut would die once Google put the old stuff up. The quality then and now is about the same, it's just that the stupidity is a lot more noticeable now becuase of the exponentially growing quantity of overall traffic.
most ISPs would probably just take theirs down rather than fight it out with the RIAA.
DMCA-itis might even be a good thing for Usenet. It's really, really easy to block binary posting, and once you ditch that stuff it becomes incredibly cheap and easy to run a news server. Text traffic wouldn't add up to even one per cent of the bytes thrown around at this point.
Yep. Python does a little startup dance looking for and loading default modules and directories, so it has more startup overhead. You can probably see from the syntax that the language isn't really intended for one-liners though.
Good thing too, because as built the Ion's got to be about the ugliest car many people will ever have seen (in markets where Peugeot is absent, at least).
That idea's not even new for GM. Their plasticars (e.g. Fiero, APV, Saturn) had that sort of idea in mind, if you believed the press releases of the time.
GPL or no GPL, Scaldera put their name on that stuff, charged money for the programs and support of those programs. If their claims of not knowing what they were selling are true, that's gross negligence on their part, and anyone who actually paid for licensing or support ought to be looking into getting their money back.

Darned if I know what that was about. Python's always had boolean operations on pretty much everything. Zero, the special value None (that's an object with no value assigned, kind of what C's NULL tries to be except that it really is different from zero), empty strings/lists/tuples, have always been false, any other value true. The new boolean type is really just there for people who want to do a little bit stricter run-time type checking, it doesn't really add any essential functionality to the language (which is exactly why its addition was resisted for so many years).
Did you just send off emails, or did you actually pick up the phone and try to talk to somebody? You might have much better luck with the latter, Google must get a billion random emails a day.

Yup, quite a few notebooks are using heat pipes. The iLamp depends on them too.
Heat pipes are good at moving heat away from the source, so you can put your cooling system in a more convenient spot, but you still need one.
