Notes about Linux, Docker, networking, databases, Python, and more, from concrete problems to technical explorations.
Linux · Docker · Kubernetes · software
Clear technology for real problems.
Technical notes to learn and explore, projects to understand how things are built, and services for developing, implementing, administering, and supporting technology systems.
A place to start
Every problem has a clear place to start.
If you want to understand a problem, start with a technical note. If you want to see how something is built, explore the projects. If you need to organize a system, review the services.
