Learn how to use tail calls and develop your first standalone eBPF application using the hello-ebpf library

We run benchmarks to see whether JDWP’s onjcmd features improves the debugging performance.

How to use another kind of eBPF maps, the perf event buffer, and run tests with docker and JUnit 5.

This week we’ll add support eBPF maps to hello-ebpf to communicate between eBPF program and userland Java programs.

eBPF allows you to attach programs directly to hooks in the Linux kernel without loading kernel modules, like hooks for networking or executing programs.

2023 was an adventurous year for me: I came into my blogging rhythm, blogging every one to two weeks, resulting in 39 articles, many of them on Foojay.io.

Or: I just released version 0.0.11 with a cool new feature that I can’t wait to tell you about…

The ability to disconnect and then reattach debuggers is helpful for many complex debugging scenarios and can help you debug faster.
