Also, most commercial airplanes are really, really big. If you hit a jet fighter or most helicopters with a Stinger, they'll go kaboom. Fire that same missle at a 747 and it may well be destroyed by the backwash from the massive engine before hitting it, and even if it does hit, it's not sure to destroy that engine, much less the aircraft. You'ld need some sort of truck-mounted SAM or cannon to have a reasonable chance at taking down something that big.
You get power dissipation in each gate or buffer that changes state because of some signal, irregardless of the direction in which the information is flowing. You can not recycle this power. This comes directly from the basic principle behind CMOS technology (used by almost all digital chips today) - you are charging and discharging a capacitor.
Worse than that, this isn't entirely a quirk of the technology; it's partly a basic limitation of physics/information theory. There's a certain amount of energy that must be expended to delete a bit of data, and that's a hard limit.
Reversible computers were intended to work around this - by having an instruction set that made it impossible to really delete data! - but they're still research curiousities, AFAIK.
The trouble here is that the whole idea of a NPOV is fundamentally flawed. Even a wikipedia article makes decisions about what facts are important and connected, and which aren't, and such decisions are inherently political - indeed, a political viewpoint is nothing but a collection of such decisions.
'Objective media' is one of the great bad ideas of the 20th century; I think we're heading back to an age of multiple, overtly biased new sources, and that that's probably a good thing.
It's not a PDA or a teeny laptop. It's a handheld webbrowser.
I can read news sites, RSS feeds, check my Gmail, all works just fine. It's also servicable as a MP3 or video player - certainly not as good as an ipod, and reformatting videos to appropriate resolutions/framerates/formats can be a PITA...
I think of it as more a compact second (ok, in my house it would be 4th) computer that I can pick up and check my mail and a few news sites without wandering off to another room to log in. I don't generally respond to mails on it - it's bad at that, but that's not the point.
Ah, that looks nice. I've heard of people running RAID-1 over NDB ('cause it's a block device!), but NBD apparently is a little flaky - there are a lot of kernel deadlock issues, and it doesn't sound like it ever quite picked up a userbase.
Understandable; the people interested in remote replication mostly aren't interested in doing it with Alpha software.:)
What happens if anybody shoots at it? Not much, probably.
It turns out you need a big gun to hit anything more than a few thousand feet up in the air; air resistance and gravity add up in a hurry. Rifles won't do it.
Not to say that I'd want to fly this thing over a real combat zone...
Which is way worse. All the extra TCP connections. The insane bandwidth-and-CPU consuming cookie stunts necessary to simulate a real session that doesn't exist with HTTP. Sure, you compare to thick clients, but how thick a client is a bunch of downloaded javascript?! That's not buying you anything.
Sure, you could replace SSH with an AJAX application, but it would be idiotic, and the same would be true of most web applications if a suitable remote graphical terminal standard were available.
OK, I'm just an ignorant caveman sysadmin, unfamiliar with all your modern XML wizardry, but maybe if the idea is remote display of graphical applications, we should have, I dunno, Graphical Terminal Emulators, rather than attempting to implement one in a web browser.
Why am I apparently the only person who thinks this? Am I missing something, or are you all insane?
Actually, it installs and runs fine under standard WINE. (Er, other than some bizarre painting bugs during multiplayer setup, but it's usable, and the game itself works perfectly...)
[mikeee is still waiting for Starcraft 2 and will buy it the day it appears. I don't care if the game mechanics are identical, pretty new 3D graphics would be sweet.]
It's scalable and has nice reliability features, but is all userspace and doesn't have all the features/operations of a true POSIX filesystem, so it may not suit your needs.
Anybody know anything about the Gray Team and their bot? Their 4th-place finish seems to be far the best of any of the 'low budget' teams; about all I can find is that it was sponsored by The Gray Insurance Co., that their IT department (and founders who were bored of spending money on yachts?) worked on it, as well as some Tulane students, and that it was a Ford Escape (small SUV) hybrid.
Small anti-tank shells (eg, RPGs) are shaped charges. Large ones (eg, 120mm) are depleted uranium or tungsten sabots; they scale up better than shaped charges do, are aren't foiled by hacks like external cages or composite armor.
Slashdot Mirror
running something with a switching power supply is much less effecient than using a fully-resistive electric heater of the same power.
Really? Where, exactly, is the wasted energy going?
Last I heard, that was actually the plan! Foil in the cover/binding, IIRC, with the tag inside so that it can only be read (easily?) when opened.

the potential for abuse seems pretty severe.... ...because, you know, governments never abuse anything.

Obviously, North Korea doesn't need nukes to defend against the US, but against a zergling rush from the South...

How does this compare with Linux Network Block Device? Sounds very similar.
There are pretty mature commercial tools for this stuff, as well - Veritas' VVR replication comes to mind.
Er, you are aware that Kyoto came out during the Clinton administration, aren't you? And that he never submitted it to the Senate for approval?
All Bush did was admit that the US Senate was never going to approve that treaty (which they weren't), and quit pretending otherwise.
I see that the British has just recently reduced their occupying troop strength below 20,000 troops...
In Germany.
It's a quagmire, I tell you! I blame Churchill for not having an exit strategy.

See, I don't think that's true.

The UN is socialism between governments on a grand scale.
No, the UN is a trade association for the promotion of executive power. Once you recognize this, its behavior becomes almost rational.
You're not a shaman until you've installed Linux on your zombie badger.

Livejournal developed their own distributed filesystem:

They don't seem to have a webpage for the team...
Sounds a bit like the self-healing minefield, an anti-tank minefield that has a built in mesh network (!) and shuffles mines around to fill in gaps.
No word if it runs Linux, though.
About time for someone to implementRFC 3093, "Firewall Enhancement Protocol", also known as IP-over-HTTP.
Buying Time-Warner was the best thing AOL ever did for its shareholders; trading vastly over-inflated stock for one that's actually worth something!
Time-Warner shareholders got screwed, but that wasn't AOL's problem...
