#parisweb, ma conférence de cœur, a accepté que je vienne vous présenter un atelier pour se mettre à jour sur les outils de la #webperf

A bit inside baseball -- how I made my blog faster: cut CI per push from ~6 min to ~2 min, and kept every home/archive page O(1) in corpus size. Principles: compute once at input-change time, put the result under a stable URL, let everything downstream pull it from cache.

Still tracking the Ubuntu 26.04 rollout.

This release introduced several critical low-level changes and improvements that are causing a slower-than-usual turnaround for some upstream packages. While developers work through these complexities, we remain in "stability first" mode.

We’ll pull the trigger on full support as soon as the core stack meets production standards. Thanks for your patience!

Most cache misconfiguration is not carelessness, it's a missing handshake.

Your build encodes assumptions: hashed filenames mean the URL changes whenever the content changes. The web server has to know that, or the assumption stays unused.

If the config doesn't reflect what the build produces, the framework's work gets quietly undone at the last layer of the chain.

Your site loads. From the outside it works. But: do returning visitors re-download everything on every click? Can the connection be downgraded from HTTPS to HTTP on public WiFi? Does your homepage count as one site in Google's eyes, or two?

For most static sites: no, yes, and yes. The web server config is the last layer most setups never touch.

Single data point by the looks of it but dang, TCP RTT from North Korea to one of our CDNs is slow AF, 1.53 seconds.

For comparison, the mean values around Europe are in the order of 25-30ms.
