Windows on Btrfs
So for the past year and a half or so I've been using the fantastic Windows btrfs driver for easily sharing files between my Windows and Linux dualboot. The driver works great and basically fully supports everything that both operating systems could ever want (and let me tell you transparent compression and copy on…

I forked SteamOS for my living room PC
SteamOS 3 (“Holo”) is the Arch-based Linux distribution built for the Steam Deck, Valve Software’s portable PC gaming device. It’s a very interesting Linux distribution even when you only focus on how it updates itself: updates are performed atomically by downloading a new read-only root filesystem to an inactive…

Designing a SIMD Algorithm from Scratch
Another explainer on a fun, esoteric topic: optimizing code with SIMD (single instruction multiple data, also sometimes called vectorization ). Designing a good, fast, portable SIMD algorithm is not a simple matter and requires thinking a little bit like a circuit designer.

The weird world of Windows file paths
File system paths on Windows are stranger than you might think. On any Unix-derived system, a path is an admirably simple thing: if it starts with a /, it’s a path. Not so on Windows, which serves up a bewildering variety of schemes for composing a path.

The costs of microservices (2020)
An application typically starts its life as a monolith. Take a modern backend of a single-page Javascript application, for example - it starts out as a single stateless web service that exposes a RESTful HTTP API and uses a relational database as a backing store. The service is composed of a number of components, or…

PostgreSQL: No More Vacuum, No More Bloat
PostgreSQL, a powerful open-source object-relational database system, has been lauded for its robustness, functionality, and flexibility. However, it is not without its challenges – one of which is the notorious VACUUM process. However, the dawn of a new era is upon us with OrioleDB, a novel engine designed for…

ZFS for Dummies
As mentioned on previous posts, I have spent the past few weeks dealing with a ZFS crash on my FreeNAS install. Because of that, not only was I forced to learn how to troubleshoot ZFS, but I also had to learn how to setup new volumes and come up with new backup strategies (between a few other things).

Slack’s migration to a cellular architecture
Summary In recent years, cellular architectures have become increasingly popular for large online services as a way to increase redundancy and limit the blast radius of site failures. In pursuit of these goals, we have migrated the most critical user-facing services at Slack from a monolithic to a cell-based…
