Cats Effect v3.7.0 is here!

This is a relatively small but mighty release that brings full support for Scala Native 0.5: you can now write multi-threaded apps using polling I/O and compile them to native binaries.

Stay tuned this week as the release train continues 🚂

Exactly the reason why I added a bunch of integration test just to validate the prod configuration on some components. Yet crap can be passed via env variables but it reduces the surface

Devfest Toulouse 2025 For the first time in years I went to an in-person conference. I took that opportunity in my hometown, at the Devfest Toulouse. Last edition I went to was in 2019 and I wrote an article about it back ...

Growing the Java Language #JVMLS YouTube video by Java

TIL #Java is getting typeclasses 😲 (source : youtu.be/Gz7Or9C0TpM?... ). My last line of Java might have 7 years old, but it's super nice to see that it's a still growing language.

Hard to tell. Like in many fields, with kids and a life to sustain, for most of us, I can understand that software engineering is “just a job”. That said, I’d also add that IMHO watching videos do not make it up for me, I prefer to read, loop back and take some time to grasp a new thing.

Gave an internal talk on variance in Scala last week. No video, slides and article here:

#Scala

good point ! The answer is most certainly "no"

Pretty sure it is not a good idea to mess around with terraform k8s provider(s) blocks at 1am 🤔

À l’opposé alors: comment faire adopter home assistant à toute la famille. Un de mes soucis étant par exemple de faire voir tout ça à ma femme comme autre chose qu’un truc de bricoleurs un peu geek

un in-depth sur les protocoles threads et matter ?

I only got to fetch api versions and topic metadata .
Definitely interested in the consumer API , and even more in the upcoming shared consumer group thing

we’ll see how far I go with it 😬! So far I learnt a lot and that was the (only realistic) goal !

Currently writing a #Scala (basic) implementation of the #Kafka protocol as part of our internal hackathon. I said it before but I'm saying it again : scodec is amazing !

A fe days ago, Kafka 4.0.0 was released. And look what's in it : the Early Access for KIP-932 : Queues for Kafka ! Quite hyped about this one I must admit #kafka

PrintWriter and PrintStream never throw IOExceptions Some days ago I realized that PrintWriter (as well as PrintStream) never throw an IOException when writing, flushing or closing. Instead it sets an internal flag (trouble=true) when an error occur...

Do you know that #Scala `Console.println` can't fail with an IOException? It uses #Java `PrintStream` under the hood, and in case of failure, it does so silently.
