I got my first computer at the age of ten. It was a Didaktik Gama, an 8-bit computer that connected to a color CRT TV via SCART. At that time, I had no idea that I would make a living from something like this in the future. The field didn’t really exist in the Czech Republic; there was no such thing as an IT professional or an IT school.
Here are some of my favorite Books:
Michael Kerrisk’s The Linux Programming Interface is a definitive guide to Linux and UNIX system programming. Covering over 500 system calls and library functions with clear C examples, it provides a thorough exploration of topics like file I/O, process management, multithreading, interprocess communication, and network programming. The book balances Linux-specific features (e.g., epoll, inotify) with POSIX standards, making it valuable for both Linux and UNIX developers.
Primer on Linux Container Filesystems by Michal Pitr is an educational article that explores how Linux containers, such as those managed by Docker, create and manage their own isolated filesystems using OverlayFS
Understanding etcd in Kubernetes from Learnk8s offers a practical guide to etcd, the distributed key-value store that serves as the backing store for all cluster data in Kubernetes. The article explains how etcd works, its role in Kubernetes architecture, and best practices for maintaining a reliable and secure etcd cluster.
