We are rewriting the mold linker in Rust and adding linker script support so that mold can link essentially anything GNU ld can, including kernels and embedded programs. This will be mold 3.0. We …

Hi friends!

What comes to mind when you hear "frontend optimization"? For most of us it's things like reducing network requests, shrinking the bundle,…

Good software design raises the abstraction level until the code communicates the domain rather than the mechanics.

How Postgres evaluates calculations when a value is unknown: three-valued logic, arithmetic and concatenation with NULL, NOT IN, aggregates and window functions, NULL sort order, and Postgres 19 IGNORE NULLS.

There are lighter and more reasonable alternatives to GraphQL.

The Linux kernel is a really huge piece of code. As a modern operating system kernel, it contains schedulers to manage processes and resources, a network stack, a handful of file systems, thousands of device drivers, and much, much more. At the same time…

Everyone is trying to speed up software development by building their solutions using bricks like third-party components or libraries. However, we forget what problems they may trigger. Today, I′ll...

Metaphors like "a sinking ship" are often used to describe codebases, but are misleading. A _business_ will sink long before code quality reaches a hypothetical floor. Technical debt has no bankruptcy, no clean reset, so metaphors that imply an end provide…

An opposite view on .gitignore files.

While I’m taking a short break from low-level programming, here’s a story by a friend of mine, Sonya, about debugging a seemingly impossible bug in ARM code.

This bug hunting saga started several months ago. While developing a bare-metal hypervisor on ARM64…

A spin-lock is a lock that never sleeps. Instead of yielding to the scheduler, the thread stays on the CPU and spins. No syscalls. No context switches. In this …

In September 2026, NVIDIA announced it is leaning into native GPU programming in Rust. CUDA C++ and CUDA Python are mature, enterprise-grade toolchains, and NVIDIA will be growing and maturing CUDA…
