Great article, this echoes a lot of my frustrations working in the software world. It doesn't help that I've experienced being on a well-managed software team working on interesting problems--it kinda spoiled me for all those othe

Hmm, it seems that all the pieces aren't in place yet. If I'm understanding correctly, the exploit technique they use relies on cross-page errors (causing errors in one page with accesses to another page), because the page with er

Awesome! I really like that tune. Hope to see it continue. I've had in mind an idea to make an open-source album of completely algorithmically generated music using my Python sound synthesis library. Of course I started with the drum p

Small security hole in this: since i0/i1/i2 are signed ints, i0 % 8 etc can be negative, and thus allow writing in the 7 bytes before r[], quite possibly leading to a stack smashing attack. So you probably don't want to run t

This looks really awesome. I hope it takes off! I'm pretty curious what it looks like though--as much as it shouldn't matter, syntax is very important. There's a lot of overlap with how I want my language Mutagen[1] to work.

Your timeit calls in the edit need the -s parameter before the first statements, so they aren't executed on each loop iteration. The overhead is in creating the class, not the instances. $ python3 -mtimeit -s 's="%s %s %s

Correct me if I'm wrong (I'm no crypto expert), but doesn't client-side hashing take away the main point of hashing passwords in the first place? If a password database is compromised, the hashes don't even need to be cr

Yup. You can get a working program with the simple: const int main = 0xC3; ...which is just a return. Or you can get fancy and make it exit successfully by clearing eax first: const int main = 0xC3C031;

Interesting. Very similar to the way ints are represented in Python (since they have arbitrary length, negative numbers are represented with infinitely many 1's in the most significant bits).

I solved it in my head, using a bit of brute force, but mostly some informal reasoning. Basically (and a tad spoilingly): Since we're dealing with whole chickens, there should an integral ratio between the two prices--that is, M expens

While that is an excellent talk, it seems worth pointing out that it's speculative fiction, these things aren't necessarily happening (though it is quite plausible).

Interesting, thanks. I see the problem, but this paper takes as a given that individuals can introduce transactions that tilt the system in their favor. I can't immediately see a solution to this, but I don't think it's neces

Actually commutativity doesn't hold either, because of dealing with NaNs (at least on x86, on a quick search I can't find a reference for whether this behavior is part of IEEE 754 or just implementation defined). Operations with t
