The idea of certificates is built in to QUIC, but certificate authorities are the client software's responsibility. Client software can ignore certificate authorities entirely, just like with HTTPS. How exactly does widespread adopt

I don't think it's categorically wrong to say something is too simple . There are accepted terms for that: over-simplification, simplistic. There's also the Einstein line: "Everything should be made as simple as possib

Even if compiler-only ILP is doomed to fail, maybe VLIW optimists are just hoping something useful might come out of everything we've learned? For example, compilers already model the CPU's pipeline and ILP capacity to inform inst

First, "innocent people can be framed" is not that simple. Without non-repudiation, you don't automatically get to frame someone for whatever. You need to provide the usual (non-DKIM) evidence of whatever you're claimin

What might be causing confusion is the difference between tagged unions and untagged unions. A union type "A | B" means "a value of type A or a value of type B". Example: function f1(): String | Integer {

Is it really that common? I often see HN posts calling for end-to-end encryption, but not homomorphic encryption. (But even "just" end-to-end encryption is more difficult than many realize.)

Sure, that's a fine argument to make. But the article says "I expect AES to outperform ChaCha20 in every single scenario", even when the very next sentence talks about a scenario where that's not true.

The standard Ruby VM (MRI) is about the same speed as the standard Python VM (CPython), aka on the slow end. Twitter famously moved from Ruby to Java/Scala, largely for performance reasons. Node.js is much faster because V8 is much fa

It seems to be a complaint against doing process-per-CPU. Let's say your server has 4 CPUs. The conservative option is to limit yourself to 4 requests at a time. But for most web applications, requests use tiny bursts of CPU in betwe

I noticed that too. I think it's because the buses are 3 stripes long instead of 4. After I changed the "--bus" CSS variable from 30px to 40px, I got the stepping effect.

Yeah, 2^48 is huge, but that gets you a collision probability of ~40%. You'd want a probability more like 1-in-a-million (or 1-in-a-billion). That's 2^39 (or 2^34), which is 1000 messages a second for 17 years (or 7 months). Agai

AES-GCM-SIV takes a nonce; if you reuse a nonce with two identical plaintexts, you reveal that the plaintexts were identical, but not much more. With AES-GCM, if you reuse a nonce with two different plaintexts, you reveal the XOR of the t
