🐞 In the new Compiler Academy video, @sjrdoeraene demonstrates a technique called Adversarial Testing which is an effective approach to catching bugs. You will learn how to break your own code to ensure its quality: youtu.be/R8mAHKw_UlQ

My partner is a cancer doctor. She repeatedly sees patients these days who need emergency care but can’t get it (or don’t due to 10+ hour wait times) because hospitals full of folks whose “personal choice” not to take the vaccine is killing unrelated people who need those beds 🤬

Dear OpenJDK vendors,
Please enable libjvm symbols in your builds by default.
For just ~2% increase in the distribution size, this greatly improves serviceability experience (1/3)

Let's discuss the nature of 'control fraud' in the corporate world, and how businesses which are legitimate in their individual components can be fraudulent in their overarching structure. 🧵

I started to create a little project to show Scaladoc and the source code for Scala library files in the REPL. More info: alvinalexander.com/scala/sho… #scala

One great use case for 🔥 graphs: profiling JMH benchmarks. As of JMH 1.24, it's as easy as this (thanks to the integration of async-profiler with JMH, courtesy of @retronym):
java -jar target/benchmarks.jar -prof "async:output=flamegraph;libPath=/path/to/libasyncProfiler.so"
🔥 async-profiler makes it really easy to generate flame graphs and gain insight where most time is spent in your #Java apps.
@baeldung has a nice intro for getting started with it: baeldung.com/java-async-prof…

Scala 2.12.12 is here! It adds compiler support for scala-async and backports substantial performance improvements to collections (chiefly in immutable.{TreeSet, TreeMap, HashSet, HashMap}). Release notes: github.com/scala/scala/relea…
