Of course there are techniques to prevent buffer overflows, but they are not always implemented properly as evidenced by their continued existence. They still pop up all the time in modern software.
... but buffer overflows do come from data.... data inserted into improperly constrained buffers such as text sent over an instant message or data in a picture. For instance, the buffer is specified as holding 256 bytes of data. You send it a few K of data. The data gets written into memory and overflows the buffer possibly resulting in a program crash or valid execution statements being written into memory and processed by the computer.
Just because a power supply is rated for 400W doesn't mean it's going to draw that much. A good 400W power supply will be more efficient (AKA draw less power) than a cheap 200W one on the same load.
If this is true, maybe there's just too much overhead to read the packets and filter them against more than a few matching sites vs blocking them at the routers.
I would place a bet that the transatlantic cable was laid from Newfoundland mostly because of the shorter distance rather than any other tech-level reason. Starting from there saves several hundred miles and reduces the risk of having to dredge up a cable off the bottom of the ocean if you get a break. A great-circle-route from New York to the UK runs right through Newfoundland.
A friend I worked with in 1997 was applying for a patent on this concept. The only difference is that he was specifying black&white LCDs (the only thing available) instead of OLEDs. So, yeah, this is old news until there's real product.
Why mine the moon? Bring it here! Let's just slow it down out of orbit and land it in the Middle East.... (and yes, that's a joke. I'm aware of what would happen.)
It's not quite the same analogy. There's always better video technology coming out every few months and within a year whatever you buy will be old news. Nuclear fusion (if it works) would power the whole Earth safely and cheaply for a very long time. I guess you could say it already powers the Earth, we just want a more direct means instead of the Plant->fuel->steam->electricity method. Regarding the video card; I would wait because a month isn't too long to suffer to have what you really want instead of always bitching about barely adequate solutions.
My opinion is still unchanged regardless. I almost made my first post an AC one because I knew this wasn't going to go anywhere. Your disability doesn't obligate every business in America (or whereever you are) to accomodate you. If you feel that strongly about it, form a hearing impaired fund-raising group and pay to have it installed in your favorite theatre or start a closed-captioned theatre. Otherwise its going to be passed down to all the other consumers as higher ticket prices. I'm genuinely sorry you're hearing impaired, but it's not my responsibility to shoulder part of the cost for the sake of your entertainment. Yeah, I might seem like an asshole for not wanting to pay 5 cents more per ticket, but with everything else in American that's being sued or legistlated it all adds up. The ADA should only be applied to things that are necessary in your life. Visual and audible bus announcements, physical access to public buildings and businesses, reasonable work-area modifications, etc. What's going too far? constant-tension ropes so that paralyzed people can climb the rock wall at REI? I'm sure that would be nice, but there shouldn't be legislation/lawsuits to get it.
Personally I'm all for the ADA as far as access to public places, but that doesn't mean that I should have to endure bright white lettering across my favorite actress' buttocks. Just because some small fraction of people can't hear it doesn't mean my experience should be degraded. Next on the agenda, pausing the movie and explaining it to the mentally impaired. If this suit passes, its liberalism gone too far.
* note, I am not advocating software piracy. My intention is to counter this FUD.
When will they do a study about all the revenue *gained* from software piracy? I'm sure there are many millions of people who would not have the skills they have today had they not pirated copies of Photoshop, Window 2000 Server, MS Office, etc.... and yes, there are open source alternatives, but they aren't common in the business world today. If piracy totally stopped, its likely that all of these millions would be forced to use open source applications and all but the most specialized commercial software would cease to exist.
Here's the concept: A service with no central server (possibly like Kazaa) that tracks users who volunteer to allow use of their computers for port 80 proxy. A user in China would just need to find one open address on this network to get onto it and from there the software would scan for IPs that aren't blocked. If enough cable-modem users used this then the IPs would change so often that it *might* be impractical to block them all. I know there are problems with this such as: abuse by people anonymizing themselves for illegal activity, DDoS from some Chinese entity sending massive requests to everyone on the network thus killing their upstream bandwidth, etc. I think it could be done, though, as long as there were enough people volunteering to overwhelm the governments filtering capabilities. Especially if a lot of prominent technology companies ran the software on their networks (probably wouldn't happen for legal reasons).
This will be my first negative post ever on slashdot. I don't really need to say anything because I think everyone else has covered it adequately. Since when does your typical geek only run one application at once? If you're running anything (even if its all single-thread apps) like Folding@home, SETI, ripping DVDs, TV Tuner card, etc then DUAL-core will definitely beneifit you.
The article says: "Because concrete is strong in compression, C-subs could sink well below the 1800-ft. 'crush depth' for steel". I don't see how that could be misinterpreted. It directly says that these subs can go deeper than a steel sub. I'm sure other hurdles such as water-tight coatings will be dealt with. How much other information in your reply did you make up? Unless you're an engineer specializing in concrete composites I would have to wonder.
The GPS would pick up off and on. The police would check the locations of all sex offenders. There would either be an indication that you were in the area around the time of the assault (even if the transmitter didn't say exactly) or that your transmitter was out of touch during the time period of the crime and you could have been at the location. Either case would be enough to consider you as a suspect. Probably the largest factor is deterrent. Only the most desparate sex offender is going to take the chance while wearing a tracker.
Not important, but just to nitpick... the main reason rockets are best launched from the equator is because of the increased speed of the earth's spin at that lattitude which requires less fuel. The least populated lattitudes would be somewhere down in the southern hemisphere. Probably Cape Canaveral and the ESA'a launch facility was partially chosen for its east coastal location, but the main former USSR launch facility at Baikonur is well within the continent. Of course, the Russians probably weren't too concerned with dropping large objects on China. The only coastal spot the USSR had was too far north (and probably too close to spying Americans).
The link below mentions two different technologies, but it looks like the nuclear fuel is used to heat Hydrogen. Seems like this would still be riskier in the event of a crash than standard LOX rockets.
If you have a link about nuclear rockets, please provide it. I won't go out on a limb and say for sure its impossible (although I believe this is the case). This shouldn't be confused with Ion rockets, which don't have enough thrust to get you off the ground. I can't picture any way that nuclear energy would provide enough controlled thrust to get something into orbit. As someone mentioned in another reply, the weight of the shielding would be at least one limiting factor.

3ware and Promise make RAID controllers for IDE. You can get an 8-channel 3ware board for around $30 on eBay.

So, I guess there are nuclear rockets, but the nuclear material isn't used as a propellant which was my impression from the post.
