I am aggregating here some more or less interesting stuff of various IT related materials which I came across this month. Some of them are strictly related to the things I did or am currently doing.
01Some thoughts
This month I made a few improvements in the release process of Apache Beam Python SDK and its CI/CD. I connected building source distribution and wheels on GitHub Action with existing release scripts to work in cooperation now. This allowed for the separate repository used for package preparation to be deprecated. I spent a lot of time working with GitHub Action, therefore I released my own action called github-forks-sync-action. It can be used to synchronise forked repositories with upstream. I also made a contribution to apache/airflow related to REST API by implementing DagSource endpoint.
