• 2026-02-08 : 10 or more reasons to not use JDK’s HttpClient

  This article explains 10+ reasons why after 14 JDK releases the JDK’s HttpClient introduced with Java 11 is unlikely to be the best option in your app.

• 2022-10-16 : Switching from Disqus to Giscus (GitHub Discussions)

  In the story of this blog I used WordPress, and using the WordPress comments
  then moved to Discus as it was better at handling spam. Then I switched this
  blog to GitHub with first Jekyll with markdown then finally to Hugo, this worked
  well enough. Then lately I’ve been a bit more displeased by the Disqus editing
  capability (no markdown (or asciidoc) support, no preview). More people
  tend to have a GitHub account than a Disqus account (for tech blogs).
  Also, GitHub introduced GitHub Discussions which was appealing to use with blogs.
  

• 2022-05-15 : Using Linux’s memfd_secret syscall from the JVM with JEP-419 JEP-454

  Linux 5.14 brought a new system call memfd_secret in order to mitigate speculative attack by preventing the kernel from being able to peek at these memory segments. Let’s use this syscall from the JVM with the _~JEP-419~ JEP-454 API.

• 2020-12-11 : Anonymous CompletableFuture threads with burstable pods

  It all started when opening a JFR recording, I noticed a very large and growing number of very short lived threads.

• 2020-11-30 : Off-Heap memory reconnaissance

  Understand the RSS of a JVM leveraging the horsepower underneath ps with the help of one or two JVM diagnostic command.

• 2020-10-26 : -XX:MaxRAMPercentage is not what I wished for

  This entry has been marinating for most of the year 2020. I should have published
  this opinion way earlier maybe end of 2019, but it took me time to realise I should split
  a bigger piece in smaller articles that hopefully made sense on their own.
  

• 2020-10-23 : Reads network addresses in /proc

  If you happen to be on a read-only container that doesn’t have the usual network utilities,
  like netstat, ss (socket stat), lsof, etc. then your only option is to leverage procfs,
  however, procfs displays some data in hexadecimal.
  

• 2020-07-27 : Embracing JVM unified logging (JEP-158 / JEP-271)

  Unified logging was introduced in JDK 9, and is available for us all, in the JDK 11 LTS.
  Like other great serviceability feature (jcmd or JFR) this was inspired by JRockit.
