Can you trust a compiler to optimize your code?
More or less the title this time, but first, a story about SIMD. There are three levels of understanding how SIMD works (well, at least I am level 3 at the moment):

Microsoft’s failed attempt on Debian packaging
You are seeing this because the administrator of this website has set up Anubis to protect the server against the scourge of AI companies aggressively scraping websites. This can and does cause downtime for the websites, which makes their resources inaccessible for everyone.

How many branches can your CPU predict?
Modern processors have the ability to execute many instructions per cycle, on a single core. To be able to execute many instructions per cycle in practice, processors predict branches. I have made the point over the years that modern CPUs have an incredible ability to predict branches. It makes benchmarking difficult…

FreeBSD Audio
I started using FreeBSD in 2016 as a dual-boot with Linux. The reason was that at the time Linux provided no support for real-time threads and preemptive scheduling but did provide a wider choice of audio applications. Today, as the FreeBSD audio ecosystem improved a lot, I am a happy single-OS user. You may ask…

Comparing Filesystem Performance in Virtual Machines
For years, the primary bottleneck for virtual machine based development environments with Vagrant has been filesystem performance. CPU differences are minimal and barely noticeable, and RAM only becomes an issue when many virtual machines are active.

Making a parallel Rust workload 10x faster with (or without) Rayon
In a previous post, I’ve shown how to use the rayon framework in Rust to automatically parallelize a loop computation across multiple CPU cores.Disappointingly, my benchmarks showed that this only provided a 2x speedup for my workload, on a computer with 8 CPU threads.Worse, the total “user” and “system” times…
