yeah, that seems to be an interesting trend - old Linux distros that were hackable at the time no longer are to the same extent, as the current scripted attacks have no option for vulnerabilities in ancient versoins of software. Don't rest on your laurels though, if one decides your box is interesting enough to target, one still has the means to - as long as the benefits for time spent are big enough.
Bitching in a democracy is appropriate, and is often the only way to get bad laws changed.
Except that Microsoft is not a South Korean entity (leaving aside the controversy about corporate involvment in government activities). How would you like Samsung lobbying for pro-SK laws in your country? And no, saying 'they have a local branch' is not a valid argument - removing Windows sales would actually hurt the local branch as well. This is a US corporation pressuring a foreign government into dancing to their tune. And while doing the same thing in the US seems to be OK for MS, doing it abroad is liable to produce quite a backlash. If they do more than threaten, I would not be surprised if governments start dumping MS on the grounds that support can be withdrawn without notice.
This should already make for an interesting argument in the upcoming hearing that Microsoft has for the EU antitrust case though.

I'm sure there's a better way to do these, but here's a try off the top of a vim noob:
How would you take the text between the second and third commas and replace it with arbitrary text? :%s/\(\([^,]*,\)\{2}\)[^,]*\(,.*\)$/\1arbitrary text\3/gc
Ignoring CSV for a minute, if you'd like to replace all text from the 20th through 23rd characters of arbitrary text with the string "abcd", how would you do it? :%s/^\(.\{19}\).\{4}\(.*\)$/\1abcd\2/gc
Please feel free to correct me/improve on this. New vim tricks are always appreciated:-)
I kind of see it from a different angle. Yes, FOSS needs commercial backing. Linux vendors have all the interest in moving it forward, as do others that provide Linux stacks/services/support. Once the ecosystem is beginning to fill in, no one vendor is irreplaceable, RedHat included. Yes, it would slow down things for a while (at most) if Redhat pulled their collective fingers from the aforementioned pies, but there are other commercial entities that could fill in the gap, as the financial incentive is big enough already. Most certainly, big projects like gcc ad glibc would shift to other support, even fork if necessary. See the XFree86 case for reference: there was enough financial interest for outside groups to pool resources and fork the project.
So my view is that RedHat is useful, but not indispensable. But, granted, they are a big resource pool that would be hard to replace if removed.
IIRC there's also a problem with heating. The SR-71 Blackbird (~Mach 3) for instance had the fuselage lined-up properly only when heated up by in-flight air friction (and as a consequence it leaked fuel on the runway, as the fuel sealing had a similar problem handling temperature variations) This could probably be fixed, but will require a cheap enough and easily maintainable thermal shield - unlike the shuttle's tiles. Not to mention that it will make for a hell of a hot plane upon landing, which for commercial uses can be... cumbersome to handle.
All in all, the engineering challenges for going at Mach 3+ are quite impressive.
the formula is right. E=mc^2 has the mass of the moving object. E=[(pc)^2+(m0c^2)^2]^0.5 has the rest mass m0. The two forms are equivalent (which signifies, geometrically, the invariance of the 4-momentum's contraction with itself)
He should have been more specific. Try to get a real grip on things like protons with energy of ~10^19eV. Especially since the theory predicts a mean free path that's way too short for any sources to reach us at that energy level (nothing fitting the energy bill that we know of close enough to Earth) Not to mention the question of what kind of sources would accelerate them to such energies.
Oh, it would have been unpossible for them not to clone Apple. After all, everybody on apple.slashdot.com knows everything noteworthy on the desktop was done by Apple first; the rest of the world is just a little slow in seeing this obvious fact. And woe unto those saying that 'learn from usage patterns' existed before in the XP start menu! or anywhere else, for that matter! And if there's any other 'new' feature they plan on implementing, it will be proven in short order that Apple had it first!
And no, combining various ideas is not innovation - unless Apple does it, of course, in which case it's combining various ideas in a new and exciting way, as Steve Jobs would have shown the world.
So you, there! stop bitching and get a Mac, now! (there, mods, this line alone is worthy of a +5 Distilled Wisdom)
yeah, but as the GP said, they probably don't see freedom as a a God-given right, but more like a state they have to work quite hard to achieve. The funny thing is, this should fit better within a capitalist mentality ('we built our freedom with our own hands' as opposed to 'God hath granted us the perpetual right to be free') but I suspect the problem has more to do with the need to constantly work at keeping that freedom - a certain quote about the 'tree of liberty' and 'blood of patriots and tyrants' would come to mind - and that is a thing not many people are willing to contemplate.
Good old linear momentum conservation is insufficient information to specify the outcome. Throw in energy balance (assuming you account for all losses of kinetic energy properly) and you have enough information for 1D collisions only - still not enough equations to determine angles; now moving to 'real life' you have to add angular momentum conservation to the mix, too. To completely specify the answer you need details about geometry (mass center, impact point) and surface (orientation, hardness and so on) This already moves the question quite a bit into engineering - and requires data on asteroids. I assume gathering such data is closer to the purpose of this experiment.
I don't know about where else he used it, but in this case it's fairly OK. Maybe you are the one who needs to look up the meaning? 'orthogonal' also stands for 'zero overlap' in the sense of 'zero dot product' - and while a dot product of experiences does not make a lot of sense, zero overlap certainly does.
I will refrain from making you an idiot and will merely question your reading ability. And I'll assume you never had to fear your own government and do not know any better, which would excuse your rudeness as misguided.
If you want to fault Yahoo, fault them for doing business in a country known for trampling on its citizens' rights. Wait, everyone else is doing it, so Yahoo is neither better nor worse than the rest.
I assume you expected Yahoo to have selflessly broken the local law and defied an official request from the government. Here's a bit of news for you - the real world does not work this way. Good intentions are no excuse for stupid means. I doubt Yahoo failed to realize the bad publicity all this was bound to generate, yet they did it anyway. Did you ask yourself why? or why the likes of Microsoft and Google prefer to comply with Chinese government's requests for their Chinese business?
Or, at the risk of repeating myself, would you have reacterd the same if Yahoo handed over access logs of a terrorist to the US government and thus landed him in... uh, say the hands of the friendly Israeli interrogation units that the US outsources torture to? As far as the Chinese government is concerned, dissidents are enemies of the State - and the same goes for those who hide and/or help them[*]. So the guy was playing with fire - not being aware of that is naivity. Just because armchair humanitarians do not perceive it as such, it does not mean that this is not a war - and in a war the unwary may even die. It's a fact of life, sad as it may be.
[*] foreigners such as you ot myself might question the ways of the Chinese government, but our opinion carries less weight than a fistful of air. The only ones who might be able to do something about it are the Chinese themselves. After all, what would you think if the Great China decided to tell your government how to run your country? Like it or not, sovereignity cuts both was. And if you think a large business is safe to defy the political powers in a totalitarian regime, all you have to do is look at what happened to Yukos when Kremlin decided it twitched the wrong way.
As I see it, the Chinese branch of Yahoo is clearly bound by Chinese laws (including the 'whatever the Chinese government decides to wish this week' law) As in China privacy from government eyes does not seem to be a right, the government may, at its leisure, require information about its own citizens - and it would be legal to acquire it following any means necessary. Anyone living under a communist regime would be aware of that. Following this point of view, if the Chinese government wanted the info badly enough, they might just have seized Yahoo's local servers and searched the logs themselves.
Now, Yahoo TOS clearly states that they would disclose information if bound so by law - and as such, this action does not breach the TOS. So what is all the noise about? Would any other webmail provider have done the same thing? most probably. This is business, Yahoo is interested in itself and not in babysitting users[*]. Yeah, it's heartless, but companies never had hearts.
It's sad that a guy wanting to fight oppression got caught and imprisonned, but these things happen all the time in this type of war - and it could have been worse, internal 'enemies' of communist states are known to have disappeared completely. The good part is that it will make others more careful. As to the/. crowd crying bloody murder, you guys should stop assuming that the Chinese government is afraid to use an iron fist just because they are showing you a velvet glove. This kind of naivity landed Shi Tao in jail.
[*] cue Clippy dancing image:
Welcome to La-La-Land. It looks like you're about to send an email that might have contents deemed sensitive by your local government. Would you like to:
That seems like a convoluted reason. Relying on SIGHUP for config reload means that you have a handle for it other than the default abnormal termination one; second, as a common modern use of SIGHUP is as the famous last word of a dying controlling terminal, becoming session leader and dropping the terminal through setsid() or setpgrp() (depending on your Unix flavour) should be default practice in this case - and indeed is for daemons.
The disadvantage is that the standard file descriptors must be closed before calling setsid.
All I can see as a requirement is:
On error, -1 is returned, and errno is set. The only error which can happen is EPERM. It is returned when the process group ID of any process equals the PID of the calling process. Thus, in particular, setsid fails if the calling process is already a process group leader.
which one handles by forking and calling setsid() in the child process. Then, if you want to never acquire a controlling terminal fork again after setsid() as init hath taken upon Himself to care about the orphans of the World and He has no cterm:-) AFAIR that was the standard daemonization scheme: fork(), setsid(), fork(), chdir("/") and close descriptors (or redirect to/dev/null as seen fit). So no requirement for closing descriptors *before* setsid() - but then again, it's ridiculously late here and I might not be thinking straight.
really, why would anyone care? Does it make it look smarter if the algorithm calls it 'quadrance' instead of 'distance squared' and 'spread' instead of 'sine squared'? The equations are the same anyway, so if there exists a simple expresion with 'quadrances' and 'spreads' there exists the very same expression with d^2 and sin^2. It's not like actual angles are used a lot in trigonometry - one plays around with trigonometric functions and their relationships, so most of his arguments against angles are dumb.
On the other hand, I would have to wonder at the intelligence of teaching kids yet a different way of looking at math without linking it back to the traditional one - they will have even bigger troubles if they need to link 'algebraic trigonometry' to other branches of math.
by the same argument, invite-only does not mean better. But you were deliberately trying to sidestep the issue, right? 'better' is irrelevant - if yahoo has more active users and it tunes itself to 'at least good enough' for the majority of them, they won't leave. Switching one's email address is a tedious business when too many people use it as a contact point. Not to mention yahoo messenger - if you have enough friends on one network you can't strong-arm them into switching just because you like a different webmail interface better.
A more pertinent point would be discounting all the bogus/spam yahoo accounts when checking numbers.
In fact, that's how Yahoo has been working since at least a long time: the server sends a challenge that the browser appends to the MD5 hash of the password and sends the MD5 hash of the combination back.
Mispronouncing words because of your background is OK - you did not know any better. If you do push up your education and should know better but still mispronounce " 'cause my Pa called it that too" (or for whatever other reason) it is a different matter[*]. You can go around asserting your own pronounciation but people might laugh at you if you state it is "proper English."
The problem with your answer is not that some random person mispronounces "nuclear" - the President of a country is supposed to be representing that country in the eyes of the world. That would require, among other things, correct use of one's own language, especially with important topics - and I have a hunch the world regards nuclear topics as quite importat these days.
