Back in 1930s Germany, there were other boats afloat to escape to. Here in 2025, you live in a globalized world. The rats are soon to be out of ships to flee to. There's no free society in the Sol system that survives rampant and unche

At the very least, authors who have been caught publishing proven fabrications should be barred by those journals from ever publishing in them again. Mind you, this is regardless of whether or not an LLM was involved.

Sure, it only "just requires" it if you actually care about your program working properly in the presence of concurrency. To reiterate, this is as true in Rust as it is in C or Zig, it's just that also Rust allows you to do b

Sure, and those use cases are just as easily supported by Rust, in a more principled manner that directly encodes the intent and resists misuse by people modifying the code later.

If we're getting philosophical, we can identify a hierarchy of globals: 1. Read-only (`const`s in Rust). These are fine, no objections. 2. Automatic-lazily-initialized write-once, read-only thereafter (`LazyLock` in Rust). These are al

No, this is overly simplistic. The features in the quoted comment are largely things that nobody other than stdlib developers need to understand. There is no bespoke subset-dialect of Rust where people are tossing around the `fundamental`

Erlang is great for distributed systems. But my bugbear is when people look at how distributed systems are inherently parallel, and then look at a would-be concurrent program and go, "I know, I'll make my program concurrent by mak

by kibwen 11mo ago
No, this is still misunderstanding. Overcommit means that the act of memory allocation will not report failure, even when the system is out of memory. Instead, failure will come at an arbitrary point later, when the program actually attempt

Rust's specific claims are that safe Rust is free from data races, but not free from general race conditions, including deadlocks.
