Ever wondered where all my GitHub contributions come from? I have document a week's worth of @conda-forge.org contributions: uwekorn.com/2025/09/18/w... I plan to do this for 2-3 more weeks to get an overview where I spent my time. I hope there is also content in there that helps others.

Today is my last day of five weeks of parental leave which means that it's going to be a hard day for my chargers. All the laptops and tablet will need to be fully charged and updated to be ready for tomorrow's work. 🔥

Nice to be back at Paris again. My PyData journey started there 9y ago with my first ever talk about Arrow. This time, I'll tell you how to stay sane when you have to deal with compliance topics as a developer.

The study on an EU-STF underscores what the Sovereign Tech Agency has championed since 2022: that lean, independent, and targeted funding can meaningfully strengthen the open source ecosystem and thereby boost innovation, competition and resilience.

@conda-forge.org and @conda.org are essential components of our stack. Thus, it is natural for us to work with the community there to make it ready for upcoming cyber(security) regulations. Read about our efforts at tech.quantco.com/blog/conda-r... Reach out, if you would like to collaborate!

Setting up mail records is not simple but www.learndmarc.com was nice to understand how things work and whether we have done it correctly.

A nice feature of GitHub Copilot Coding Agent: I can start simple changes from my smartphone via chat, e.g. write an internal enhancement proposal. While it would be higher quality if made manually, it enables some more things "on the go".

Finally, I caught up with what other CTOs seem to be doing the whole day 🤣

Really proud seeing my working student Paul Müller presenting his work on automated license scanning with conda-deny at #PyConDE

Recently switched to ghostty.org as my Terminal. It removes latency that you did not know you had. But: I also switched a lot of my coding to LLMs as I nowadays do more one-off scripts or small apps. Got that latency back again 😂
