I think the idea is that the scrypt hash does become the password, but it's a better password. A password with a lot more entropy (kinda). The increased kinda-sorta entropy makes the use of a slow key derivation function on the serv

If novelty-based searches were better at developing "exploratory skills", shouldn't they outperform the traditional approach when ranked on how well they explore the new maze? But the video shows that they don't.

Gravity actually acts kind of... weird... in an infinitely large uniform universe. You end up with gravity acting like a time-dependent position-independent scaling factor on position. Leonard Susskind goes over the derivation (for Newtonia

The linked papers are at least interesting. I liked the one about finding a sequence of measurements that can detect if you're trying to emulate an n qubit quantum state with just n classical bits (there's also some other restrict

I've tried to figure out what exactly the paper is saying. They start by noting that this circuit: │0〉-H─•───√X-[=1!]─ │0〉─H─┼─•─√X─[=1!]─ │0〉─H─┼─┼─√X─[=1!]─ │0〉───X─X────────── (will now =1 when measured) Which p

I'm also surprised attribution is required. If there was a "no by" opt-in, I'd opt in.

Gravity gets double-negated when you reverse time. Its units are over seconds squared instead of just seconds. A simple way to see this is to imagine taking a movie of a heavy back arcing upward through the air then back down. What do you s

Communicating between quantum computers will probably involve photons. They're pretty good at traveling far fast coherently. ... Not good enough that we won't need to use a quantum error correcting code and repeaters that pump out

Those are great developments, and they shift the pareto curve of cost-vs-readability-vs-speed downward, but the curve is still there.

You realize having to write better code is a bad thing, right? It makes writing software more expensive, and decreases the supply of people who can do it. Also, people aren't going to start valuing craftmanship because you added mo

Running a tweaked client like this seems really risky. Bitcoin is a consensus protocol. If clients disagree about which blocks are valid, you lose consensus. You're allowing attackers to inject controversial blocks that fork the his

This is really impressive. I can't see any seams in the merged output, though I do see the actors' eyes creepily going out of alignment (a fixable problem).

> They seem very conservative in their claims. Hahaha! D-Wave's reputation is one of exaggeration and putting marketing before science. That's how Scott ended up as de-facto "chief D-Wave skeptic": he kept complaini

Using the post's title on hacker news is probably misleading. It sounds more official out of context, whereas in the post the "award" is just a tongue-in-cheek framing device: > -Truth in advertising: The Web of Language

I always assumed that chip/pin being used was at least checked by the credit card company. The machine should be telling them if it supports chip/pin, and the cc company independently knows all the information about your card, s

Almost all of this paper is dedicated to discussing whether or not computers can be "creative". Then it mentions in passing that computer-discovered theorems may be long and impenetrable (even if they are profound). I guess I was

It's not a typo. When two ships are moving fast relative to each other, they both determine the other's clocks to be ticking slower. http://casa.colorado.edu/~ajsh/sr/paradox.html

For example, you could have a parameter on the cert that caused clients to probabilistically reject it 1/10000'th of the time when in the last month of the cert's lifetime (so there are really two deadlines, the probabilistic

I missed that. It certainly wasn't clear to me from the rest of the post that the author realized they were talking about a cache. Possibly because I'd be tempted to make that the focus , since I consider "by the way we just

So... a cache. You keep track of a bounded number of items, and can avoid doing some work when a currently-tracked item shows up again.

The whole point of let's encrypt is to be fully automated. Without that, it's just yet another crypto tool with poor usability.

The main problem with that series of videos, if I remember correctly, is that it only ever gives high-level descriptions of experiment outcomes. Those are interesting, but they aren't really good explanations. Then to top that off, the
