Anyone running a federating instance of the Matrix homeserver Synapse will likely have seen this: synapse is database-hungry. It tends to take a lot of space. In this post, I'm documenting how I shrunk my homeserver database from 100GB to a little under 8GB, during a long maintenance cleanup. There …

Today, I was working on optimizing my travis builds to speed them up, especially in the direction of caching. Travis allows you to set cache: cargo in your .travis.yml to enable caching for rust projects and caching is cool: it avoids having to rebuild all dependencies all the time …

Finally, it was done last week, Smithay has its own website. Over the past months, I've moved my wayland-related projects to the Github Smithay Org, and after a lot of work on smithay (the crate) itself with @drakulix, we've released the 0.1 version! This is a great milestone for …

Disclaimer: This is a subjective and personal point of view. As such, please take it with the grain of salt it deserves. I just want to share it, hoping I'm not alone feeling that way. 😊 Most Rust aficionados agree on this point: Rust does have a difficult initial learning curve …

This blog post is about the new design of my wayland libs. It's not a tutorial, but rather about the design choices I made, and why I made them. I'll start with a quick recap of what wayland is, from an API & protocol point of view. If you already know …

Hi all. During the past few months, I've been working on some crates for using Wayland in Rust. Now, they have reached a step that I could call "mostly usable": not yet finished, but a good basis to start using them. So I'm writing this note to present them, and …

Je me suis récemment acheté un Banana Pi R1. Cette petite bête, fortement inspirée du fameux Raspberry Pi a toutefois un but assez différent. En effet, elle dispose de 5 ports Ethernet Gigabit, ainsi que d'une puce wifi. Il s'agit d'un routeur personnalisable presque complètement open-hardware. Disposant également d'un port …

Yesterday, I did a presentation about my wayland crate at the rust meetup at Mozilla in Paris. Here are the slides and the project on github.

Je me suis depuis peu mis en place un système pour monitorer mes différents serveurs, en utilisant collectd, un service permettant de collecter et remonter et centraliser de nombreuses métriques sur des serveurs linux. Néanmoins, l'interface d'affichage des métriques le plus classique, Collectd Graph Panel, bien que simple à mettre …

Les emprunts (borrowing) et les durées de vie (lifetime) sont deux concepts centraux de Rust. Ils peuvent parfois s'avérer difficiles d'accès, car finalement très intriqués l'un avec l'autre. Je m'en vais donc écrire ce billet, en vue d'en expliquer les tenants et les aboutissants. Résumé des bases à avoir Je …
