Even in a modern browser, a renderer exploit (the most sandboxed portion of the browser) gives you access to a large attack surface - the browser process via IPC, the kernel via syscalls, and loads of data from other websites. So no, an exp

We’re talking about coding competitions here. These models have been fed the entirety of ACM, SPOJ, LeetCode, and whatever other competitions they can get their hands on. They are good at constrained coding competition tasks, and certainl

Looking at elliptic curves over the reals makes for pretty pictures, but really fails to convey why ECC should be secure at all. As an example, the function m => m^65537 is a completely useless encryption function over the reals because

Importing immigrants directly into the military sounds like a bad idea. I’m guessing many would be less likely to want to lay their lives down for the new country, so drafting them seems like a great way to end up with a bunch of disloyal t

A good family friend caught abdominal TB while abroad, came back to Canada, and was terribly misdiagnosed. TB is very rare here; abdominal TB even more so, and early symptoms look like a lot of other diseases. It took several hospital visit

I mean, can’t they just train on some huge codebases? There’s lots of 100KLOC codebases out there which would probably get close to 1M tokens.

That's brilliant! I mean, arithmetic is the same way, right? Nobody should do the arithmetic by hand, as you say. Kindergarten teachers really ought to just hand their kids calculators, tell them they should push these buttons like thi

FYI: a kernel patch to run exes isn’t needed. binfmt_misc can handle this, and wine-binfmt already exists to automatically run PE files through Wine.

This exploit is just wild. There are just so many little tricks connected together - using multiple image files with unexpected formats, aligning heap chunks to sit on easily-predicted and manipulable addresses, deserializing a huge object

It’s not being processed in the kernel - BlastDoor is a heavily-sandboxed user process. This attack chains together a bunch of exploits - including an encrypted BlastDoor sandbox bypass - in order to gain full control over a device.

Normally, there would be a bounds check to ensure that the index was actually non-negative; negative indices get treated as property accesses instead of array accesses (unlike e.g. Python where they would wrap around). However, if the JIT c

FWIW: this type of bug in Chrome is exploitable to create out-of-bounds array accesses in JIT-compiled JavaScript code. The JIT compiler contains passes that will eliminate unnecessary bounds checks. For example, if you write “var x = Math.

Additionally, it requires allocating memory for every operation. With a mutable bigint type, or fixed-size large integers (e.g. uint256) we could skip a lot of allocation overhead. I have previously prototyped big integer algorithms in Pyth

You're on the right track! The length of the cycles mod 10^k is simply Euler's phi function of 5^k: 5^(k-1) * 4 (or a factor of phi(5^k); AFAIK it is always exactly phi(5^k), although I don't have a proof of this handy). The

I am already doing that (thanks to `pow(x, y, z)` in Python). The numbers I'm working with would have trillions of digits were it not for this trick - way more than 1GB. 1GB is what I use to store all of the candidates, in an ineffic

Fun fact: 2^133477987019 is the smallest power of two that ends with 40 even digits. In fact, it ends with 46 even digits - which is surprising, given that it is significantly smaller than 2^(2^46). The last 50 digits of this number are ...
