@netflix.com skyscraper live was nice, but really use **metric system**, this doc is gonna be watched worldwide.

@cnn.com hey when I read your articles, I always appreciate when metric units are used (both shown are ok). I hope you could pursue this effort consistently in all your articles. Thanks in advance

In new lazy constant preview, removing isInitialized feels like a mistake: querying the state of a lazy field is genuinely useful. Also, API ergonomics are inconsistent: collections use the standard Collection API, but single values require LazyConstant. Kotlin integrates lazyness better.

WasmGC is coming to GraalWasm, unlocking the power of JVM garbage collectors for #WebAssembly! This will also get GraalWasm a lot closer to implementing the full Wasm 3.0 spec. Join @ssmith.bsky.social and me at @jfokus.se next month to learn more: www.jfokus.se/talks.html?s...

Today I learned via @jpbempel.bsky.social about JSR 45, used to add extended source debug information. This was used for JSPs, and it appears to be used by @kotlinlang.org in as well to ease debugging, which is likely useful for `inline` functions or multi-source types. Spec jcp.org/en/jsr/detai...

USA 🇺🇸 Le compte de la Maison Blanche vient de publier ça. L'Amérique de Donald Trump veut agresser les Européens.

There's some kind of cognitive dissonance when I see Broadcom and Spring together...

Trump commence déjà à faire des allusions à une annulation des midterms. Et quand il le répétera encore et encore, tout le monde fera mine d'avoir oublié qu'il avait déjà lâché "plus personne n'aura besoin de voter" pendant la campagne de l'an dernier.
