Setting up Cygwin CI environment for testing one of my projects took more than fifty trial-and-error attempts - that's why I think it will be useful to leave some written notes on the issues I've encountered. Here is the end result - GitHub CI running some Makefile tests in Cygwin. Cygwin gotchas … -
Don't blindly trust Docker for the selfhosted stuff
It is my strong belief that you shouldn't go crazy with all-things-docker when deploying selfhosted services at home. Online forums, especially r/selfhosted, seem to foster an opinion that providing a Dockerfile or better yet a docker-compose.yml or even prebuilt public images on Docker Hub is an acceptable way … -

Enhanced file path completion in bash (like in zsh)
Zsh offers a lot of significant improvements over traditional shell experience. Some of those can also be implemented in bash, but others are not. For a long time I've thought that advanced file path expansion is something that can't be done in bash. Today I prove myself wrong. Background When … -
Liberating effect of Ansible
Maintaining two or three Linux machines is not that hard of a task. For many years I have thought it was not worth the effort to automate - regular backups and version-controlled configuration files seemed to be just enough. And then Ansible had blown my mind. History It all started with … -
Accidental submersion into web development
The Library Problem I love reading books. My wife loves reading books. We enjoy shopping for books and we live a ten minute commute away from a huge used books store. That means we have a lot of books. Like, really a lot. A little more than one thousand. We … -
Excel as a CSV editor (with VBA)
One might think that Excel is a decent CSV editor as it is, but it's not. It is a very capable CSV reader, I do not dispute that. When it comes to writing though, Excel does not match what you'd expect from a mature application: It might change the delimiter …
