How does Code Caching work for Chromium&#39;s V8 JavaScript compiler? Deep dive by Leszek Swirski on how repeat views not only leverage the browser cache for the network response, but also the compiler bytecode. It even includes a limited amount of state snapshot if the initial execution appears deterministic (eg save runtime execution logic for defining and exporting functions). Good reason to keep library code definitions simple. https://v8.dev/blog/code-caching-for-devs #webperf #v8 #...

Tony Hoare passed away. This quote stuck with me since I first read it as a teen. It sparked a decade-long obsession with simplicity, later expanded by Rich Hickey&#39;s Simple vs Easy. &quot;I conclude that there are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies, and the other way is to make it so complicated that there are no obvious deficiencies.&quot; https://en.wikiquote.org/wiki/C._A._R._Hoare#The_Emperor...

WikiApiary is back online after having been down and overloaded for a long time. Bawolff brought it back and did a ton of full stack performance work to optimise the whole system. Adding HTTP caching, tuning InnoDB, and more! https://blog.bawolff.net/2026/03/giving-wikiapiary-kick.html #MediaWiki #WikiApiary #Wikibase #Wikidata #VinylCache #VarnishCache #MariaDB #MySQL #webperf #SRE

Fastmail @fastmail has been operating on bare metal for 25 years. Their planning and (over-)provisioning strategy reminds me of Wikimedia. Situations where cloud renting is cost effective for medium or large companies are vanishingly rare, and always have been. As with so many big tech patterns, this is a myth held up by VC-backed startups and incentives. https://www.fastmail.com/blog/why-we-use-our-own-hardware/ #Fastmail #baremetal #sustainability #CloudExit #CloudRepatriation #selfhosted #...

Oh my, a web component? on jquery dot com? minibar is a 2kB standalone search widget. Accessible and progressively-enhancing (works without JavaScript!). An alternative to the popular 100kB DocSearch.js widget. It goes well with Typesense, an awesome FLOSS open-source alternative to Algolia. And it&#39;s (if you want, and yes we do) self-hostable! https://github.com/jquery/typesense-minibar Demo: https://jquery.com/ or https://qunitjs.com/ #webperf #typesense #ProgressiveEnhancement #al...
