🦎 Hi geekos! If you’ve been running containers on your Leap or Tumbleweed machine, you probably started with podman run commands. Maybe you moved to Docker Compose files to manage stacks. Those are great tools, but they have a limitation, as they don’t integrate natively with systemd, your operating system’s init system. When your server reboots, do your containers start back up automatically? If a container crashes, does it restart? How do you view its logs alongside your system journal? ...

👻 Void in the Basement I have a basement, and I have a problem: no WiFi signal in said basement. I have also a piece of e-waste that refuses to die: a Samsung N130 netbook from 2009. It has a single-core Atom processor and 1GB of RAM. By modern standards, it can barely open a web browser. But for a Linux terminal, It’s a supercomputer. Instead of buying a generic ~10€ WiFi repeater, I decided to turn this little warrior into a fully programmable, secure, and transparent WiFi router using Void Linux. Here is exactly how I did it. ...

😸 TL;DR Being lazy, I made a tool to run qcow2 images for my convenience. It now supports x86_64, aarch64, s390x, and ppc64le. Feel free to use it if you find it useful! 📖 The back story If you’ve ever typed qemu-system-x86_64 into your terminal, you know the feeling. A creeping dread. A cold sweat. The QEMU headache. It’s that special migraine reserved for developers who know they’re about to spend the next ten minutes deciphering their own shell history to remember that one magic flag for networking. ...

▶️ Intro : Let Me Be On the previous post we continued our journey with a more complex scenario, using a mix of gdb and valgrind to trace all the function execution inside a given binary. This time, hold on because we’re cranking up the complexity. We’ll dive deeper into low-level analysis and explore how to use Intel PIN, a powerful dynamic instrumentation framework for manipulating and inspecting executable code at runtime.
