I am still boggled that programmers who claim to be interested in security (and who moreover claim to be uninfluenced by marketing and "cool", but rather by technical concerns) still choose C or C++ for their projects.
I agree that unsafe languages are on the way out for most applications in the long run. There's just no reason NOT to prevent these errors automatically. Code reviews and "being careful" are not solutions. There's no good reason for a language to be full of "undefined behavior" black holes.
And yet I'm a hypocrite, as I use C++ for most things (except Perl for text processing and little utilities). Why? Because the maturity of the tools, availability of libraries, and performance.
I don't feel performance and GUI appearance are inherintly degraded by VM's, but in today's world, they are. Every Tom Dick and Harry has an interpreted scripting language with a bunch of different unstable GUI bindings, but that's not good enough.
I'm afraid that Linux is losing ground to MS on this front. Microsoft's CLR is here to stay and has good development tools. Soon most apps for Windows won't have buffer overflows or invalid pointers anymore. They'll still be open to other things, like email worms, but regardless it will seem increasingly senseless and frustrating when yet another buffer overflow attack is found in a Linux app.
You don't need stegan-what-he-said. The picture can be the message. When the picture on a webpage changes, you carry out your instructions.
But your method only communicates one bit (presense or absense of the image). So how do they know what instructions to execute when they see that image? The instructions must be prearranged through some higher bandwidth medium. Ideally, that would be face-to-face communication at a time and place distant from sending the bit. But that is very limiting when you're trying to run a global jihad. You could prearrange a huge catalog of messages, but you'll still be severely limited unless you leverage combinatorics - forming something like an alphabet. But then (whoops!) you're right back to cryptography and the messages might get cracked.
Your method is indeed hard to defeat, but mostly because it's so severely limited in expressive power.
I've got an IBM R40 (Celery 1.6) running SUSE 9.1 and I've had no problems with any of the hardware, including power control and my handy-dandy keyboard light.
I don't believe it. "Power control" should include ACPI, which hardly works at all under Linux. Also do you have 3d acceleration and suspend-to-ram working together?
Wonder why it takes more power to spin a dvd than a hard drive platter.
Well, the problem is that hard drive spins all the time anyways, whether or not the DVD is going. In theory you could get the drive to spin down, but on Linux there's no practical way to get the OS not to access the drive at least a few times per minute. It would be nice if there were.
Suggestion - don't play DVDs from your laptop!
Copy them to the hard drive before you leave instead. Spinning the DVD takes power and makes noticeable noise on some models, and without the DVD drive in the option bay you have room for a second internal battery.
I run my T40 this way, and get great battery life, about 4 1/2 hours of video playback. It doesn't go up a lot if I'm just word processing though, since it can play back video locked at the slowest speed (600MHz).
Truck bombs in financial districts, airliners into skyscrapers and anthrax through the mail will be quite viable weapons no matter how much better our infantry gets.
Those are not viable tactics for conquering and overrunning a country. While we are swatting down terrorists, we should also stay prepared for the possibility of a future enemy that could pose a serious military challenge to us in the way that the Soviet Union did.
I don't mean to minimize the terrorist problem, but I'll eat my hat if we ever lose more people to terrorism than car wrecks in a given year. Hopefully this nation will never again have to fight for survival, but "never" is a long time.
It's not like they aren't already carrying radios. How do they reduce the risk? I'm no expert, but I believe tactics include using extremely high or low frequencies, super-short transmission bursts, spread spectrum, low power, frequency hopping, and encrypting messages to closely resemble noise.
I wouldn't assume they're planning on using 802.11b D-Link gear from Best Buy.
Wall Street should be called Speculation Street. You win some, you lose some.
So what's the take home lesson here? Don't buy stock that will go down? Why didn't I think of that.
It's easy to say "don't take a risk, just keep slaving away in your cube for that guaranteed $55K/year," especially after a company crashes and burns. But to escape the treadmill you must place your bets at some point. So how do you do that shrewdly? If you wait until it's a "sure thing," it's surely too late.
I'd say they are very much getting it. They are using brand recognition in one area to expand in another.
The fact that google is #1 and Microsoft is not shows that Microsoft - and you - are in fact not getting it.
Anyway, it's their party and they'll invite who they want to. You don't have to go there if you don't like those terms.
This is irrelevant. Nobody is disputing Microsoft's right to offer a crappy search engine. For that matter most of here would rather they continue to execute your cross-branding strategy and lose the search battle.
Well, Microsoft made the gesture of idemnifying their customers, so you could say that Windows users are safe.
In a sensible world, this would be tantamount to selling insurance against an invasion by Martians, but things being what they are who knows? The SCO suit against Autozone, last I heard, was stayed pending the outcome of SCOs case against IBM, rather than being completely thrown out as utter nonsense, so perhaps there's some legal theory under which using a product makes you liable for the actions of the product's developers. As obviously stupid as that is.
What's maybe more strange is that Sony's CD Walkmen already support both Atrac3 and Mp3. So it would appear that Sony does get it, at least to the extent of knowing what consumers want - and just doesn't care.
Those CD players are really good, with tremendous battery life (like 35 hours on 2 AA), compatibility with high bitrate and variable bitrate mp3's, handling of diretories and subdirectories, etc. (Mine crapped out after a year of jogging with it, though, so I went for a flash-based player.)
If Sony wants to make a splash, they should make a DVD mp3 Walkman. A DVD model would have the same storage as an iPod mini, but instantly swappable for another disk. You could fit about 100 hours of music on a single DVD. It could work so long as they keep the price well below generously-sized hard drive models.
This isn't a very specific answer, but each generation of players has significantly more battery life than the previous - even solid state ones, which can use the very same memory cards as their predecessors. Sony is awfully good at this - their MP3 CD Walkmen run on 2 AA for about 35 hours. The iPod is getting a little old and behind technically, but I'm sure Apple has plans for the next generation.
But let's imagine you have a cluster with 1024 diskless nodes. At that scale, you need a ridiculously high per-node mtbf just to get anything done before your cluster breaks down. This might be a lot simpler and cheaper than trying to manage redundancy at higher levels.
Or maybe you're building a chip to control antilock braking, or for that matter an airliner or a space ship. Even if the odds of braking something handled by this mechanism are fairly low, it might still be worth it.
2. Buy a PC. If I'm going to do that, then I'd be springing for a Good video card. Recent figures from my coworker puts a useable box at about 900$. Plus the game. 950$.
3. Xbox + Doom3 for Xbox = 200$.
Well you certainly won't need a $900 PC to play the game at 640x480, which is what the XBox will give you.
Also keep in mind that a lot of great actors, particularly British ones, as far as I can see, tend to be very reluctant to sign on to movies with bad scripts.
I don't know about you, but I don't feel like I'm getting my $15.7 Billion worth in the first place, why pump more into it? The ISS is a massive boondoggle, $100 Billion over time and for what? The best science NASA does seems to be the cheaper stuff.
We can't increase funding for agencies that are doing a good job, and increase agencies that are screwing up and attributing their problems to budgetary shortfalls. At least not forever.
As for the DoD, well the trip to Iraq is a big expensive boondoggle too. But one does not justify the other.
That's why a small and very selfish portion of me wouldn't mind if TiVo lost these abilities. I already do all these things on my computer, and going mainstream tends to spoil things.
Well I didn't expect this. Not even released yet, Doom 3 runs at 1600x1200 on "high quality" at 68 fps on the Nvidia 6800 Ultra, or 42 fps with 4x antialiasing. In other words it can just barely make use of the best hardware at the time of its release. That's fairly conservative in my book.
Was it necessarily such a big mistake? Just because you work on something extremely successful doesn't mean it benefits you. Companies don't work that way.

You don't rake in 80% profit margins year after year by undercutting the other guy, you do it by being the #1 and only.
But if too many of these "linux switches" turn out to be bluffs, MS won't be so generous with the discounts.

leads to consolidation, right? Not that any of us would ever accept that p2p has weakened music sales...
