I have a box running Windows 2003 Enterprise Server, as my home router+web server+mail server+VPN gateway+file server, through my MAPS subscription.
The only time I reboot it is to apply Kernel security updates. Its average lifetime between said reboots? 86 days.
The longest I've ever run it? 213 days.
At neither of those junctures did *it* crash and reboot. I always rebooted it manually, and it hadn't leaked resources out or anything. It was just as responsive as the day it was booted.
This is on an eMachines shitbox, too -- no enterprise-grade hardware here.
My XP Pro desktop runs pretty flawlessly, too. It doesn't leak memory, and if it weren't for the fact that I have one of the worst motherboards in existance which has from day 1 routinely refused to POST one out of four tries, it would never crash. The only reason it crashes is because I'm running it on flaky hardware, the underlying system is sound.
If you don't fuck with your computer in ways with undefined behaviors, or defined-yet-detrimental behaviors (i.e. you don't start clicking on things on System Properties without knowing what they do, and you don't install viruses and spyware) you won't have any issues.
Linux gets unstable and crashes if you start to screw with the Kernel's options too much, and there are certainly applications that can leak memory, too.
*How* you use your computer is as important, if not more important, than the particular computer you are using.
The time-vs-accuracy tradeoff is a big one. One client which I know some people who use, takes almost 48 hours to index a full hard drive of files to share, and hash them all.
Anything less robust, you're liable to have collisions, such as these, apparently. Any more, and if you have a lot of files, there's a major time committment before you can actually begin to serve anything -- most people aren't willing to have their CPU pegged for 2 days straight while their P2P client hashes their 35,000 MP3s and 200 movies, or so.
I'd argue that the definition of crime is implied and understood as anything that, according to the laws of the country you are residing in, would land you in jail.
Granted some of the things that are defined to be criminal, might not necessarily be immoral. Take, for instance, recreational drug use. I am strongly opposed to this type of behavior, personally, but people can argue various different viewpoints. Bottom line, however, is that if there are laws on the books against it, and you do it anyway, you've committed a crime.
Upstream bandwidth is largely a technical problem more than a billing/political one.
Take a cable modem.
It listens for a powerful, high-SNR signal from the head-end. This signal is, IIRC, modulated as some variant of QAM...64QAM sounds about right. There's a lot of bandwidth to be had here.
The return, however, is a relatively weak signal, transmitted by relatively cheap equipment, and using modulation which emphasizes error correction and reliability over raw speed (QPSK). It certainly is *possible* to have more upstream bandwidth, but the equipment needed to do so is a lot more expensive, generally, because it has to be able to transmit at a higher power. And, its not offered, because the existing infrastructure is set up such that the source transmits loudly with expensive equipment, and is very sensitive, allowing the clients to be cheap and weak by comparison.
I'm sure your telco would be willing to sell you a 6mb symmetric line...for $1k a month, and requiring Cisco equipment to use.
You can learn anything, whenever you want...but the extra effort required to do some kinds of learning at different ages, is exponentially greater than if learned while young. Depending on what you're trying to learn...it might not be worth it.
I imagine that, for some of the more automatic structures of the brain (visual nucleii, etc) which serve as sensory relay stations, it's simlpy not possible to rewire the brain in a way that will take advantage of the full capabilities of new sense. (I imagine this can be offset by application of neurological growth factors applied to that area while stimulated.)
Your state of mind can, to some degree, influence your phisiology...but, again, there *are* hardcoded limits as to how far that can go.
I loved the premise of the show, but knew it was going to be a failure the second it aired.
Too much of law is citing precedent, statute, and such...and if they make those up as they go along, they've got a show that's internally consistant -- but nobody would care about, because its too far out there.
If the application only has one active segment of code in memory...it doesn't matter how many processors there are, if there's only one unit to actually execute.
Multithreaded applications spawn off multiple segments of executable code in memory to do different things...a network scanner that operates in a multithreaded model might spin off a thread for every few hundred connections, so it can handle more in parallel.
"Multithreaded" applications are built to parallelize easily, as each thread can hit a different physical CPU. Single-threaded applications will also benefit from multiple CPUs/cores, but less directly: a single-threaded app would have less resource contention on a multiple CPU system, vs a single CPU system.
The OS scheduler is the deciding factor for what-goes-where and there's some hefty math involved for a lot of it...most of that, however, is handled automatically and transparently (although you can "force" affinity to CPUs if you're so inclined.)
Actually (but without reference) there's a new kind of hybrid engine that was in R&D that could accelerate a fully-loaded dump truck to cruising speed (35 mph) under electric-only power from a standstill, in less time than capable with current diesel engines.
The downside: "fully loaded" for one of these things meant.7 of a normal load, because the electric equipment took up more space.
They're working on it...a loaded dumper probably weighs about as much as any of the big rigs out there, so it's a good place to start.
The point is that it's more economical to move the production of electricity out of your car's engine compartment, and into a massive structure dedicated solely to that purpose, hundreds of miles away.
Emmissions are confined to a single source, the electric company can product power cheaper and more efficiently than most consumer vehicles, and when the power plant changes to fusion or another alternative fuel source, the car doesn't have to do anything different.
I think its an economy of scale issue...also, when electrical generation switches to a different original fuel source (solar, fission/fusion, space-collected, whatever) the interface to the car will be the same.
It's like the fuel-cell car problem, except it moves the problem further away from you: When the *power plant* changes its energy source, the energy output is still the same thing, and they only have to retool one plant, as opposed to retooling every gasoline filling station and internal combustion engine in the country.
If it were somehow possible to chemically inhibit the aggression regions of the brain, then yes, this would be possible.
Unfortunately, lowering the levels of certain neurotransmitters implicated in aggressive behaviors would ultimatley kill the person: the same chemicals are needed for many other, very important brain functions.
I am in an environment where I have to change my password every 90 days...and every time I change it, the complexity requirements get more and more bizzare.
I was originally assigned an 8-character, all-lower-case + 2 letters alphanumeric password. It was computer generated. I kept this password until the first expirey, then changed to another password of the same length, lowercase + digits.
Then the third expirey came around. Suddenly my previous passwords were off limits -- and I needed to use more distinct letters and numbers.
The fourth expirey came around, and I had to now use capital letters as well as lower case letters, in addition to numbers.
My password on this system has ballooned from a phrase that I could easily type in a second, and was still difficult to guess, to variations on the pattern "QWERTY" or similar on my keyboard. Anyone who watches me type my password, knows what it is without any effort at all.
The anal security policy means my password will be virtually bulletproof from the outside -- and paper-thin to someone standing over my shoulder.
I would absolutely LOVE to see some kind of coup d'etat by IETF, to take over control of the Internet.
They're the hands-down technical authority, they create/publish the standards. I imagine there's something they could do to make ICANN have a hell of a time doing anything.
That's what I loved about B5, that never really appealed to me about Star Trek: the show was very realistic and down to earth (as much as a fantasy space drama can be.)
Watching the series again post-9/11, I noticed a bunch of insightful commentary (the Night Watch episodes) which seemed to parallel the Homeland Security situation we're currently experiencing.
I don't see anything wrong with saying "Portions of this program are covered by patents owned by Microsoft Corporaton, licensed for free under the provisions of $TERMS" in a comment in your headers, or the Help>About menu.
Slashdot Mirror
When I came to college, I bought a 6-foot power with around 20 outlets spaced about 4 inches apart, down the length of it.
Cost me $49.95, but it's been worth it. It lives behind my desk and gives me a straight drop of power to whatever I need.
Honestly now.

It's not me :p although I wish it was, damn, I can't even hold a third of that collection in my storage space.
uhh I guarentee you that wasn't me.
Your maths were pretty accurate, he's got 748 GB of media.

I imagine the discs will contain revoke list..."all allowed to play EXCEPT xxxxxxxxxxxx"
This preserves forward-compatibility.
Agreed...back in the day I had some kind of program that wouldn't export to MP3 unless you paid extra for it.
.MP3, it worked fine.
So, I exported as WAVs, with MP3 as the compression scheme...then renamed to

I doubt it would be too difficult to code -- if we knew the mechanism by which it proceded.
Its hard to code a procedure to replicate the working of the mind...if you don't know how the mind does it in the first place.

That's an aside, however.
For $90.7m, I'd do more than just pretend.
Why? It sounds moderately European more than anything else.
Then, the GPL is too strict.

Basically that's what I was trying to get at. Thanks for flushing it out from the Linux side of the picture, I neglected that aspect of the equation.
