Crime is a symptom of a bunch of stuff we can't change easily (including genetics). Fencing in your neighborhood actually works really well at reducing rapes, murder, and robbery. The whole "discounting what you mean to preserve" talk makes you sound like someone who doesn't have a family. In a decade or so, I imagine that you'll have a more mature opinion.
If the cameras don't work, then how much harm could they have possibly done to liberty? The police state Chicken Littles aren't rational and can be ignored.
What articles like this make me think, is "how can I make these cameras work to fight crime better?"
This isn't a shock. It's called putting pressure on the Chinese to grant basic human rights to their citizens by using the Olympics. Sorry that you don't feel it's important.
Whoa, getting personal? Why don't you come back when you've been away from university for a couple of years and had a real job. Until then, fuck off wanker.
Last year we had an issue with spammers targeting our postfix server to do this. They would insert an extra Delivered-To line, which postfix would happily bounce back to wherever the spammer wished. I wound up writing a header_check for this. Last I heard there were no plans to change postfix's default behavior.
We support 3 Macs out of 200 computers in our labs. We used to have a lab full of them, but nobody ever used it.
Apple's warranty service is execrable. We had one machine sit there broken waiting on a new motherboard for 6 months.
The replacement motherboard gave out last month (the extended warranty expired last year), and we had to take it down to the Apple store, because we can't just buy a replacement part like we could for a PC.
Macs are just fine for personal use, but Windows is far better in a lab environment. It's easier to administrate, reasonably easy to keep secure, and very easy to buy hardware and software for.
Ever heard of 'group wheel'? Or 'sudo'? There isn't a big difference between Ubuntu, RHEL, OS X, and Vista as far as privilege escalation goes. If you try to do something that needs root, you get a prompt. And each of those systems have a lower class of users who don't even get the prompt.
Exactly. The statement that gets thrown around is "the right tool for the job" -- a statement which satisfies nobody because it says nothing.
The fundamental truth of programming is that talent matters, and that some people have it while some people don't. All great software is created by people with talent.
If you don't have talent, then stay as far away from C++ as you can. There are great languages out there for you, but they aren't C++. If you do have talent, then C++ will reward the time invested in it.
The greatest asset of C++ is the seriousness and quality of the people supporting it -- the people who work on the new standards, the people who contribute and maintain Boost, the people who work on well-used libraries. There isn't a stronger community of programmers out there.
Second, no, this "could have happened to any OS" is wrong. A well-crafted browser (in this case, the browser is part of the OS) can in theory prevent browser plugins from accessing anything of importance. However I don't think any existing browsers do that - but they should.
Irony alert: IE7 is the only browser on the block that does this. I imagine that the vulnerability was accessed through the open-source alternative: Firefox.
And no, it's not because IE7 is part of the operating system. It's because IE7 uses Microsoft's secure API to achieve sandbox mode. Firefox really needs to start taking advantage of this API. Otherwise their "most secure way to surf" bullshit is going to be called into question real soon.
And if they used https instead, about.01% of their users would be computer savvy enough to check the certificate when the warning pops up. People just click through. Even technical users simply assume that that the certificate was allowed to lapse or something. https is not a panacea for man in the middle attacks.

No, the original poster was exactly right that pi = log(-1)/i. The analytic continuation of log(z) is "multivalued" in a lot more places than just the branch cut (in fact everywhere). Take any point, circle around the origin, and you've added 2*pi.
The whole point of analytic continuation is to extend the domain of definition of your function. It's wrong to think of log(z) as a plain old multivalued function. Instead, what you're really doing is defining your function on a manifold (a space that is only locally R^n). In the case of log(z), it's an infinite corkscrew. Everywhere on that surface (a Riemann surface) log(z) is defined as Log(r) + i*theta, where z = r*e^(i*theta)
The choice of branch cut is actually somewhat meaningless; what matters is the path that one takes to the point in question. Starting from the real number line, if you go around clockwise (increasing theta), you come to theta=pi and can evaluate it there. The answer is unique, log(-1) = pi*i, since (as you yourself said) log(z) is a holomorphic function.
The only point that you can't do much with is log(0).
For a discussion of log(z), see Churchill's Complex Variables. For a nice picture of the complex corkscrew that you get from log(z), see Penrose's "Road to Reality."
Logic isn't generalized problem solving though. It's a lot more specific. Logic is a method of talking about equivalencies of statements. A few axioms about lines and points are equivalent to all of Euclid's proofs, etc.
So it's a very understandable mental module -- being able to say whether two natural language statements are equivalent or not -- that gives us all of math and physics.
No, it's unlikely to be the placebo effect. It's more likely to be something called 'withdrawal.' Try the same thing with alcohol, caffeine, or tobacco. You won't be any happier because you've started taking it, but your friends will notice one hell of a decline once you stop.
So, all the politicians who had voted for abortion bans before Roe v. Wade should have been arrested for passing unconstitutional laws?
You do realize that Constitution masturbation isn't actually that helpful towards realizing good government? Canada, Britain, etc., all have reasonably free and decent governments despite not having the American constitution. In other words, it's people and culture that make good government, not written constitutions.
Finally, whichever party controls Congress will really love having the Speaker be able to kick out whomever he pleases right before tight votes.
Historically (with the XP service packs) most update instability was caused by malware. I imagine that the same will be true with the Vista service pack roll-out.
When SP1 is actually released, get yourselves ready for a billion lame Slashdot stories about how Vista SP1 blew up some poor sap's computer, killed his dog, and slept with his wife.
I take it that you don't have health insurance? Because everyone knows that 20-year-olds never get appendicitis and need to pay for unexpected medical expenses.
And "universal" care is something to brag about, you dumbass.
Obama's plan is more expensive because it's not mandatory (healthy 20-somethings won't sign up). It will actually cost more. Where does the money for Obama's plan come from? I'll give you a hint: Not the tooth fairy. It will come from taxes: people's pay checks.
As House likes to say, "everybody lies." Even Obama.

I've got one and I like it. The Zune software in its current incarnation is miles ahead of iTunes (something definitely not true about Zune v1).

LVM shouldn't be used except on drives on a redundant RAID level. As long as you take that basic precaution, it's fine and can be fairly useful.

I've never heard anyone suggest that Cain's wife was any person other than a sister. The PI=3 thing I've heard before, but only from real idiots.

It's not that amazing. A brain that wasn't reality-based wouldn't evolve in the first place.

Be thankful that you aren't a WebCT admin. You wouldn't believe what a pain that is.
If they had AI that could run on fast computers, then they'd have AI that could run on slow computers, just slowly. They don't, sorry.
