I really like Zig, but it's difficult to compare it with Rust without mentioning Rust memory safety and data race freedom.

I think most of us in software engineering assume the probability distribution has a fat tail. I've seen some authors name this the "blowup factor". For instance, your most likely estimation is 10 days, best case is 5 days, a

If the simulation is like containers and VMs, then for sure we'll find a way to escape the sandbox :)

I mostly agree, but having used Linear.app which has a crazy good and fast UI based on a local database synced with their cloud database, I'm not sure anymore: https://youtu.be/WxK11RsLqp4?t=2170 . I think it's imp

The fact that database engines written in Java exhibit high latency is not a reason to dismiss all other programming languages except C and C++. It still makes sense to consider modern languages like Rust, Go, Zig, etc.

I agree that most of the time the segfault will happen later during program execution, which makes debugging very tricky. From that point of view, Java preserving memory safety even in presence of data races is a big win. I guess that'

You're right. That's a big advantage of the JVM. It's memory safe even in presence of data races. That post from Russ Cox (again) explains quite well why Go is not memory safe in presence of data races, and what should be cha

I agree that a data race on an interface value in Go, is worse than an infinite loop or a memory leak, because it can lead to calling the wrong method on a value, which is hard to debug.

by ngrilly 5y ago
Yes, the JVM will keep executing the program, but I'm still not convinced this is strictly better than segfaulting if a thread is stuck in an infinite loop using CPU for nothing, and another is leaking memory.

I see your point now. Yes, Java won't segfault, unlike Go on slices/maps/interface values. But even without segfaults, undefined behaviors due to race conditions can still be pretty in Java (causing infinite loops, memory lea

When I compare the codebase of a tool like gqlgen (a GraphQL library in Go) with the code base of PostgreSQL or SQLite, I'd say even 10% is generous.

Seems similar to fly.io, but fly.io seems better: uses WireGuard instead of service mesh, supports custom domains, supports any TCP or UDP service, provides volumes, etc. But that’s great seeing more options in that market!

Apologies. I thought I pasted the original link but I was wrong. Thanks for fixing it.
