This is actually a good point. If you're never accessing inside a string directly, but only iterating over it, then it's often far better to build a tree/rope structure than to create a continuous memory section.

I saw someone on Twitter complaining that this behavior can be confusing since without being aware of it you can create drastically slower code. However, I must say that I find this approach quite pragmatic and neat. In most cases, string c

The comparison to ".d.ts" seems apt since both are languages/grammars focused solely on declaring types. How they are interpreted is a different matter of course. TypeScript assumes they are strict declarations of the JavaScr

Not sure if I agree. In physics you typically have the analytical solution, but it's expensive to evaluate (integral over many dimensions) so you use machine learning as a cheap way to approximate it. In most other cases of machine lea

This reminds me a bit of Aeron ( https://github.com/real-logic/aeron ) which is a reliable UDP uni/multicast transport library with built-in flow control. It's written in Java and seems to have superb performan

Congratulations on launching! It looks like a great product. Some technical questions which I didn’t see answered on my first glance: (1) Is it a single-server only, or is it possible to store data replicated as well? (2) I’m guessing that

I'm not sure if special relativity applies in the context of quinoa. No scale is going to show a difference in the mass of quinoa caused by relativistic effects of heat differences.

I think one understated advantage of serving plain HTML is the reduced surface of things that can go wrong. Once you see that the server has sent a "200 OK" response you know that everything is good and the user will see the conte

assert() by itself is typically not the same as "defining an invariant". An invariant is an expression which should be true for the whole life-time of the block/function/program/anything, but assert() only defines a

You're bringing up good points. Chain replication seems neat and I haven't quite figured out why it's so rarely used. Maybe it's partly because it's not request/response-oriented (the tail is supposed reply dir

I'll have to admit that over time I've ended up with mixed feelings about this paper. This is mainly due to people reading this paper without knowing much about consensus and drawing conclusions like "Raft is better than Paxo

You only need to define 0.9… as 9/10 + 9/100 + 9/1000 + …. Without knowing how that series converges you can then use the two expressions mentioned to conclude that it has to be equivalent to 1.
