 In the recent weeks and months, the [FSFE Web Team](https://fsfe.org/contribute/web/) has been doing some heavy work on the [FSFE website](https://fsfe.org). We moved and replaced thousands of files and their respective links to improve the structure of a historically grown website (19+ years, 23243 files, almost 39k commits). But how to do that most efficiently in a version controlled system like Git?

 I own and manage 30+ domains at [INWX](https://www.inwx.com/), a large and professional domain registrar. Although INWX has a somewhat decent web interface, it became a burden for me to keep an overview of each domain's sometimes dozens of records. Especially when e.g. changing an IP address for more than one domain, it caused multiple error-prone clicks and copy/pastes that couldn't be reverted in the worst case. This is why I created [**INWX DNS Recordmaster**](https://github.com/mxmehl/inwx-dns-recordmaster) which I will shortly present here.

 I had the pleasure to moderate the OpenRail Day 2025 in Paris, organised by the [OpenRail Association](https://openrailassociation.org) to share knowledge and experiences about open source software in the railway industry. The event featured several talks and panel discussions with experts from different companies and organisations involved in open source projects related to railways.
