Because ever more CPU-demanding app-development, and ever more screen-real estate (photo/film/games/tv) demanding apps are suddenly gone ? People don't need to type anymore ? I don't get it. I've heard 'photoshop through the web is going to be here in five to ten years' for the last fifteen years now. It hasn't happened.
plastic.com just had one too many Bush bashing topic on it. I was pretty active on it at the time, but man - the leftiness left a stench after a while.
That chip is really, really good. I've tried it for several projects, and even though it came second to the freescale CPU's because of the requirements - if there wouldn't have been those requirements (of the industrial kind), then that marvell chip would've won out. Big time.
I'm like you, and the only use I could see for a tablet was inside a car. As a click-on, do video for people in the back, and navigation for people in the front type of thing.
I was making a database that would replicate (using slony) to a (very small, embedded) client during its (the client's) boot-up. Here the database lived on a ramdisk. It would only monitor changes (upon other events). If anything would happen during operation, I would just have rebooted (nothing ever happened). Those WAL-files and their apparent obligatory nature really got under my skin at one point.
Yeah, but you can't have *zero* WAL logs (even though you have no use for them), and their size is *compiled in*. And yeah - materialized views are a good feature.
Does it have materialized views yet ? Oh, and can I configure it so that it doesn't have those two ridiculously huge undo-type files so I can use it on smaller hardware (hey - it's fully replicatable now, right ? That includes scenario's where you replicate from a big master to several small slaves) I know, I know. Keep pushing the bar. Congratulations guys, from a happy user.
It depends what you call an 'encryption algorithm'. If you mean 'DES', then no - DES is nowadays considered a weaker algorithm. If you mean 'AES-256', then still no - you need to *apply* AES-256 before it's any good, because AES is a block-cipher and will re-encrypt identical blocks of plain-text with the same key to identical blocks of ciphertext. If you mean 'AES-256 in CBC mode with random IV and SHA-256 HMAC authentication', then that's an algorithm that can be safely used. Under certain real-world circumstances.
No. You cannot distinguish between the two. If you could, you would have an attack vector against the encryption. The trick, once you have a key, is to have authentication-strings in your data structure, so you can see whether the key you used is actually correct, and the decrypted data is actually useful. An attack based on this authentication string, is one of the many, many possible attack vectors against encryption. Also, 'random' is not always very 'random'. In the world of cryptography, we need serious random. C'mon dude, how far are you with this ?
The point is more: given some technology or other, is the atmosphere replenish-able faster than the solar wind blows it away ? My guess is that yes, it is.
In that case, it's probably already contaminated. I doubt that Russian tech of the seventies, or US tech of the nineties for that matter, could render a huge object 100% sterile.
The device would have to unremovable (which requires sensitive anti-tamper cabling through it, with power on those cables), it would have to be able to do real time crypto (both for transmitting data, and for being able to answer to challenges, otherwise its messages could be replayed by a ground-based antenna while you wrap the original device in metal), it would have to be able to transmit over a fair distance, and perhaps through walls, and it would have to be able to 'sting' - presumably using electricity, and it would require a portable power-source to do all this.
And then you haven't dealt with the risk of 'no reception', or answered the question of 'where are we going to do location - by triangulation or GPS inside the device ?'.
I can tell you now, from experience, using current-day technology - that's not going to be a very 'portable' device.
But if it's neutrino's doing this, *and* there's a notable difference to what happens to these experiments, depending on what side of the globe you're on, then the amount and the effect of neutrino's racing through earth, us, and whatnot cannot be in any way insignificant, meaning that they must, somehow, interact with us. You know. Give us cancer and that sort of thing. Make us more heavy, I don't know. Or do neutrino's *only* affect isotope-degradation-experiments ?
... Managers are conservative and want something proven to work, rather than the latest and greatest.
Except when Sun says that Java is 'enterprise ready' and 'proven technology' (I heard this gem when Java was oh.. six years old and had libraries to do, well, practically nothing) - because then anything goes. Nothing against Java, mind you - just saying that a big name and lots of marketing go a long way in turning that notion upside down.

To beam energy to a vessel, you have to cross the atmosphere. Methinks you're not just going to only heat up the vessel.
And scheduled your post to appear after the fact ? Cool.

No it leared to spell from Slashdot's editors.
Pinkie in the cheek: "One million dollars!"
That's a lot more effective than I thought.

Is editorial independence such a foreign concept to you 'mericans ?

I think the 'moderator' (interviewer, really) unloads. That man talks way too much about himself for an interviewer.

make it compressed header-less audio. Give 'em a decoder (which will produce noise), and claim you're a scientist and this is you recording Jupiter.

Teach the controversy !

Adam may have been. Just like, as is proven by history, at least a couple of million Chinese and Egyptians.
I have no idea what your point was, but man, that was beautiful.
