The "Rust syntax is not that bad" people have not yet discovered that the expression `x = y + ..` parses as `x = (y + ..)` while the expression `x = .. + y` parses as `(x = ..) + y`. In other languages, the precedence of an operator depends on that operator. So it makes sense to…

Want to do cross-language profiling? The profiler that our team at optimyze and later Elastic has worked on for the past few years has been open-sourced today! We also released a first preview of the local dev UI for it along with that (it's free)! elastic.co/blog/elastic-u…

This book by @m_ou_se brilliantly explains memory ordering, interior mutability, and the art of safe and efficient spin locks.

Rust 1.68's std::pin::pin!() macro refines pinning, offering safety and expressiveness. Usable as an expression, it adds flexibility and is well-suited for immovable async objects and complex structures. #rustlang

It is now easier to safely "Pin" something on the stack, using the new `std::pin::pin!()` macro. 📌 Unlike pin macros provided by some popular crates, std's new pin macro can be used as an expression: 3/11

In Rust, when creating a string always consider doing it with some pre-allocated capacity (::with_capacity(n)). If you don't the string starts with 0 capacity and will require a memory allocation when you add some content to it.

I wrote a really simple RISC-V (rv32i) JIT for x86_64 designed for gathering some stats for my upcoming Bluehat IL talk. It runs at about ~1 RISC-V instruction per 2 x86 cycles, and can create and run hello world ~8.6 million times per second on 96 cores! github.com/gamozolabs/rv3…

The std::fs::remove_dir_all function in the Rust standard library is vulnerable to a race condition (CVE-2022-21658). We will release Rust 1.58.1 with the fix later today. Read the advisory: blog.rust-lang.org/2022/01/20/cve…

Here's the DAC authorization library I wrote. It allows you to specify specific grants for principals interacting with resources and enforce (at compile-time) that all of the appropriate authorization checks have occurred. crates.io/crates/dacquiri github.com/resyncgg/dacqu…

Another exciting new feature in @rustlang 1.53: Nested or patterns. 🦀✨ This allows you to use the `|` or operator anywhere inside a pattern, instead of only at the top level: Before: Some(A) | Some(B) After: Some(A | B)
