Why not just developers, like Steve Balmer once said? Why not just managers? Why do you need someone who understands how software is written and who also understands how it can be tested, packaged, deployed and maintained in an automated manner? I think this question answers itself, doesn’t it? I’d like to bring up an… Continue reading Why DevOps?

When I first tried to write and run pipelines in GitLab first thing I got were errors. I tried to create a json file containing data that needed to be accessible in each job of the pipeline. This was an id generated randomly in the first step and each following step would rely on this… Continue reading GitLab: Persisting data between jobs

This is not a problem with locally installed tools and commands on Linux systems but when custom programs should be executed this can get a little bit tricky. When you log in as a… Continue reading Making applications available in non-login shells

Source code is volatile and when a team is working on the same code it can get let’s say “messy”. Especially when unused stuff is not removed and obsolete practices are applied. And to be honest, when the task of changing the logic is done I don’t start cleaning up my code. Fortunately there is… Continue reading Improve code quality in Eclipse
