I work with William on a daily basis, and have found him to be among the most humble and respectful of anybody that I've met in the world of mathematics. On what do you base your snide remark?

What's most disturbing about this, is that if somebody looks at kiddie porn while using your hotspot, you are *required* to keep it around. So, all one has to do, is spoof a MAC address, download kiddie porn, and keep it in a logfile. Report it every so once and a while, and voilá, you've got a transparent, totally legal cache of kiddie porn.
My first question was, "Is this really worthwhile?" I mean, Xtreme Notebooks has quad core laptops for about half the price of this -- and for that much money, you can get just as good of a video card, 4GB ram, and some beastly hard-drives, too. So what are they charging for? A fancy case-mod?
No, you are totally wrong. The system measures the ratio of the sender to the spam of the ratio receiver receiver, and establishes a negative false-positive ratio by building a score based on the spam-spam ratio of the sender receiver. By collecting the sum total products of the receiver sender spam ratio dividend, the sales pitch drives the likelihood of three emails through the foobar baz@incompatible.
In summary, I have no idea what I'm talking about because I didn't RTFA. That I am aware of this fact makes me superior to the lot of you who are arguing over the inner workings of this week's spam-filter vaportech -- which was probably written up in an incomprehensible and inconsistent manner such that it will go over the heads of foolish investors, and part them from their money.
I fix typos and bad grammar anonymously. In my area of expertise, I fix definitions and proofs. Also anonymously. When they stop allowing anonymous edits, I quit.
w00t. 16, to 21 bytes then. That's still a *tiny* key. Given that the popular collision method is "insert garbage into the file", one needs only "replace file contents with garbage" instead.
MD5 is what, 64 bytes? Your file will probably be less than a terabyte (2^40 bits), so it'll have a representation of 40 bits, or 5 bytes. So now you have a 71 byte hash. Are you going to tell me that 71 bytes is really "a lot harder" than 64? You're delusional.
The problem is that data is intrinsically incompressible. If you map the space of all finite sized binary words into the space of all binary words of n bits, you have an infinite-to-one map. If you want collisions to be "hard", you increase the size of your target space. If you want 'em to be really hard, you're playing against the future, which is almost always a losing bet.
Naw. Even if you GPL a short snippet, I can use it pretty much any way I like, under fair use. So, short snippets are pretty much always under public domain.
Public Domain is for people who write software to get a job done. I GPL my code when I believe that it is original, or somehow innovative. When I write "easy" stuff like basic framework, memory management, data structures, etc., I release it to the public domain -- it does the job, and I don't care what others do with it.
Facebooks' policy is, and has always been, "It's better to ask forgiveness, than permission" with regards to policy. They claim to be for your privacy, but whenever they roll out a new feature that might be a privacy concern, they opt you in and don't make any sort of announcement so it can be months before you notice that you can close out such features. I used to be on facebook, and I recently closed my account because of such bullshit. A lot of my friends, my fiance, my mom, etc., acted rather put-out like I'm intentionally avoiding them or something. It's wierd how much pressure I've felt (though not from my fiance, she gets it) to re-join. News like this is just what I need to show people why I left.
I'm hoping that this gave RMS a coronary. "No! It's GNU/Linux!" *gasp* "No, damnit, it's the GNU GPL! You fools!" *wheeze* "You're getting it all wrong, GNU comes first, not Linux!!!" *hurk*
Because if somebody gets that file, they've got your password. This way, they'll have to hack your brain, as well as your computer, to get at your password.
Yes, he did. Our new slashdot overlord command him to.

Sage has a very good solution to this: Cython. It's a very easy language, almost identitical to Python, which can be used to bind C to Python (for instance, we use GMP and GSL extensively through Cython) as well as compile Python-like code to C, which can be accessed by Python & vice verse. It's very intuitive, and very fast.

Wow. I've never seen the phrase, "I don't know anything about this topic" drawn out into such a long statement!
Disclaimer: IANAM (I am not a mathematician), but I'm applying to grad schools in math, and I work with mathematicians who use computer-aided proofs on a daily basis. Most mathematicians are not concerned with such loose and squirrely concepts such as colliding universes. We care about actual mathematical objects.
For instance, the proof of the four-coloring theorem -- first it was proved by purely mathematical means that every planar graph is essentially the same as one of a few thousand small "representative" graphs. By "essentially the same", I mean that if the representative graph is four-colorable, than the original graph is, too. Then, use a computer program to color each graph with four colors. Finally, give the results to a couple of independent teams and have them verify that your coloring contains no errors.
This isn't the mess of tweaks & hacks that you describe. Now. With closed-source math software, one can never be sure that provable methods are used. With open source, one can.
Sage has bugs. You can fix them. Try that with Mathematica.
Ok, following that logic, free yourself from the oil companies. And while you're at it, the food distribution monopolies. Actually, that isn't hard in Seattle. Ride a bike, and eat vegan, locally grown food. Far too many of my friends have done this. Freaks, the lot of them. But the power company bit is tricky, I'll give you that.
If it's any encouragement, I'm just finishing up my BS in Math, and currently taking a graduate course in algebra. And I don't get about 50% of the article. (note -- the wikipedia article has *nothing* to do with physics, it's just algebra & geometry) All I can say is, if you want to understand this stuff, grab a pencil and write down every definition you see. Every time you see a term whose definition you can't rattle off instantly, read it again.
Certainly not. This boils down to plausible denial, really -- the lady whose computer got stolen by the cops claims to not know where these encrypted files came from. That's most likely bullshit, unless the British government has some evil scheme, along the lines of:
1) Arrest animal rights activist
2) Plant encrypted (or random) files on said activist's computer
3) ???
4) Profit!
I'm thinking that perhaps step 3 might include interrogating some fluffy animals, without fear that the activist would complain. This sounds quite reasonable to me. Good thing Slashdot is on the case!

Every set can be well-ordered. Those two problems are apparently the endpoints of the interval of uses for Sage.
