Fun fact, how to go faster than HTTP/2.0 on an API?
....
Using HTTP/1.1 :D
The story behind: being able to use the MAX_CONCURRENT_STREAMS value to respect it can be very challenging depending the lib you do use so 1.1 *can* be faster for you

Ce coup de gueule de Rob Pike (co-créateur de Go, et de l’UTF-8) sur l’IAGen est salutaire et rééquilibre l’ambiance positiviste et dépourvue de recul qui domine dans la communauté IT.

played a lot with #java 25, #jbang (why not quiet by default!), #groovy #grab, #kotlin #dependson and none is that smooth when it comes to handle dependencies with real portable IDE support...think I'll go with #java 25 and a pom.xml to handle my scripts with deps for now

TIL that you can create indices concurrently in Postgres using `CREATE INDEX CONCURRENTLY ` and in MySQL with `ALGORITHM=INPLACE, LOCK=NONE`.
This is tremendously convenient when you use automatic migration on multi-hundred GB tables that happen at startup and don't want this startup to take hours!

You maybe missed it but #ApacheSpark can now log OOTB (using spark-submit) in #JSON: spark.log.structuredLogging.enabled=true
this is big for integration and ops!

Another step to the long awaited #ApacheMaven 4.0.0: Apache Maven 4.0.0-rc-5
Still a few known bugs but we're getting there and already makes "rc4" more usable, grab it while it's hot!

I really love @jetbrains.com but still fail to understand why #rider is so poor in dev XP compared to #idea , I know the #dotnet backend is not as great as the #java tooling they did (even if more portable) but doesnt justify all, #nunit assertion "diff" are a pain for ex, test "configuration" too 🤔
