With many concurrent readers and a single occasional writer, which mutual exclusion primitive should you use? Let's look at the assembly to find out.

Wherein our hero learns the arcane secrets of the u128 sword in the depths of the Underrust.

Raw notes on Rust's HashMap design and implementation

Raw notes on CPU optimization

A software system is transparent when you can look at it and immediately understand what it is doing and how.

Don't dismiss the statistically probable

How does Rust allocate a zeroed Vec and what does it cost?

A Rust object that survives program restart thanks to Rust allocators, systemd's file descriptor store, and syscall memfd_create.

On Linux what can you turn into a file descriptor and then monitor with epoll?

How does Rust return values, and does it make any difference to us programmers?

When is the linear scan Two Sum solution faster than a map? What if we use AVX-512 instructions?

In Rust, what is the performance cost of using sync::Once after the initial setup?

In Rust, how does using a different primitive type (u8, i32, u64, ...) change the generated assembly?

Assembly: In all the world of the programmer, there is no more important output.

Can we make a Rust program that's as small as it's assembler equivalent?

Thanks to Address Space Layout Randomization you can use the address of a stack variable as a zero-cost random number.

Rust avoids memory copies by optimizing return value placement.

On x86 it doesn't really matter what sync::atomic::Ordering you choose.

Safety is boring, let's do pointer arithmetic.

Linux's epoll API solved the C10K problem, enabling fast and afforable Internet services.

Minecraft has an API. If you run your own server you can program it from Python.

An adventure in CPU out-of-order instruction execution.

Rust's traits are a single concept that unifies interfaces, abstract classes, mix-ins, operator overloading, contraints on generics, and more.

Just a normal day reversing linked lists on the whiteboard.

It will take longer to learn than most languages, the standard library is small so you'll need dependencies, and a lot of behavior is in traits.

In Go, what's the simplest possible way to put all your ad-hoc tools in one place?

In Go, how do you run several operations that might return an error, and return those errors at the end? Here's how I do it.

Two days at PDX DevOpsDays, a gathering of system administrators who use version control, and write a lot of YAML.
