Funny you should ask. I just looked into this: https://twitter.com/dakami/status/884715382061252608 Yeah. Ethereum blew up and all that compute is going towards GPU Mining.

My understanding (and please correct me if I'm wrong!) is that it's pretty easy to burn out FPGAs, electrically, in a way that it's not particularly trivial to do with other sorts of circuitry. So one downside of exposing yo

Rust isn't a sandbox. The whole point of a sandbox is it survives incorrect software at runtime. Rust is compile time magic. Sure, cool, different thing.

Does Webstorm actually integrate with front end development? I'd like to whip together simple projects that aren't actually hideous, and literally every cloud IDE I'm finding just doesn't have a way to go from HTML5 cod

Are your Win10 devices domain joined? Sounds like malware.

So I just started experimenting with ZFS, because it seemed required for container snapshots. Then I found out it fragments badly, and nobody can figure out how to write a defragmenter. So, uh, keep the FS below 60-80% full apparently. Yea

Ah, there you go. Repro code: #/usr/bin/python from random import * count=0 def get_bit(): global count count+=1 if (count%2)==0: return random()<0.9 else: return False def get_fair_bit()

I'm not convinced Von Neumann debiasing is vulnerable like you think. You're dropping runs (00's and 11's) so you don't care if it's 90% 0 or 90% 1, you care if there's an even number of a run or an odd n

It's definitely based on my approach, but it's missing the concept a bit. The only way this approach gets entropy is if you cross two clocks at very different speeds, and get randomness from the mismatched tolerances. For exampl

I'm interested in more of your perspective here. I was around back in the Mojo Nation era as something of an observer, but there's lots maybe I didn't see.

That's exactly what makes this cool! Since we know the signed hash is a chunk from the Blockchain that is most assuredly not Sartre, we also know with cryptographic certainty that Wright does not possess a copy of Sartre with that has

I like the metaphor that ants are "cells with legs". Life really isn't constrained to any of our neat categorizations; life really is whatever works over time.

You might be right, you might not be, in the general case. In the specific case getaddrinfo is not performance sensitive (to say the least) and that entire block could be specially compiled 10x slower or run inside of a trivially available

Very specifically, I'm interested in exploit mitigations that eliminate undefined states, rather than just hope an attacker doesn't know enough to redefine them. One can show "zombie pointers" (fine, we've got lots

No argument from me about the seriousness of issues like Rowhammer. Computers are built in layers, and layers require reduction to logical assumptions. The degree to which Rowhammer destroys logical assumptions is astonishing. However, we

If this bug ends up traversing caches, it'll affect Amazon just like everything else. That the bug is so resistant to clear-cut answers on cache traversal vulnerability is unique, practically unprecedented.

What I'm saying is that a lot of energy has gone into "Assuming an attacker has gotten us into an undefined state, let's try to prevent them from pushing us into a chosen redefined state." And what I'm saying is, m

I stand corrected, there are in fact a decent number of people who mentioned HMAC(K,X)==HMAC(H(K),X) when len(K)>blocksize. So, you had no reason to cite Solar Designer and I shouldn't have implied you should. Sorry about that! St

Sure! HMAC keys are exactly one block long. But lets say an app wants to have a key that's two blocks long. No big deal, hash that app key and now two is one. Ah, but now let's say the attacker has control of input keys. He can
