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 …

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.

was that...like...a hundred megs for a web page?

We don't build houses (he said from San Francisco)

-D flag in OpenSSH.

No apparent backend integration.

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 …

Are your Win10 devices domain joined? Sounds like malware.

It's kind of silly. There are design tools that don't let you write JavaScript. There are JavaScript tools that don't let you write server side JavaScript (or any other language). …

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 defragme…

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() def get_fair_bit(): while 1: a=get…

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 num…

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 rando…

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.

Where does he claim this?

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 …

He said something was X, we have cryptographic proof it's Y.

Everything before Bitcoin was really obsessed with anonymity, whereas Bitcoin was actually scared of centralization.

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…

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 "zomb…

I've updated the post with further details.

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 Rowhamme…

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, …
