    AWS are really acting like vultures with OpenSearch, blindly forking every bit or Apache-licensed Elastic source code and rebranding it as OpenSearch. They recently raided the Elasticsearch client libraries, forking them all… 1/5

    First iteration of the automated veggie garden watering system done. The electronic part was a breeze thanks to @esphome_ and @home_assistant! I can't say the same for the pipe burying part 😅 Next up: automatic switching between rainwater tank and city water, moisture sensor...

    Just discovered that HTTP status code 451 "Unavailable For Legal Reasons" exists. This number, in the 4xx "Client errors" range, is a reference to Ray Bradbury's Farenheit 451 in which books are illegal...

    Euh... En 2000 on avait des modems 56k, alors on faisait plutôt la chasse à l'octet. Et les animations c'était en Flash ou en applet Java, généralement limité aux menus/navigation et aux bandeaux de pub. Quand aux grosses libs JS, ben... il n'y en avait pas.

    "Anyone who uses YAML long enough will eventually get burned when attempting to abbreviate Norway: `NO` is parsed as a boolean type, which with the YAML 1.1 spec, there are 22 options to write true or false."

    🚨🚨 That's a lot of YAML 🚨🚨
    No body wants to write YAML. A lovingly curated list of YAML pain.

    I'm starting a new role at @elastic today, joining the Elasticsearch team to work on the Java client: API modeling, code generation, network layer and managing community feedback and contributions. Open source code as my day job again! I will also contribute to the Rust client 😋

    🎉 The new Elasticsearch Java Client I've been working on for the last 6 months is now public. Still experimental but already usable! The API code is generated from a formal spec of the API, which is no small feat considering its size and complexity! 🥳

    Today I've been promoted to tech lead of the SDK/clients team at @elastic, focusing on statically typed languages and our code generation tooling 🎉 This is a great team of polyglot language experts, developing opensource client libraries in 9 different languages. Cool stuff 😉

    Quelle honte cette "analyse" ! C'est comme si on disait "la température baisse" en comparant la température à midi au soleil le lundi et celle du milieu de la nuit en fin de semaine...

    Yay ! Ma conférence "Introduction à Rust embarqué" a été acceptée à @DevoxxFR ! Trop content ! On va faire du live coding, depuis une LED qui clignote jusqu'à un serveur http embarqué !
