Everything around LLMs moves fast. To produce meaningful content, I need to automate the tedious/boring bits. Thus, I took the release of Inkling-Small as a proxy to do exactly that: uwekorn.com/2026/08/01/s...

The short hype of Inkling-Small or why I need automation to blog about the latest LLM developments

On Thursday morning, I was excited to see the release of Inkling-Small. Last week brought us Laguna-S-2.1 which is a pretty good coding model given that it fits onto a 128GB RAM MacBook Pro. Sadly, La...

My coding setup now includes local LLMs but no more permission prompts - sharing my recent improvements in AI coding (setup): uwekorn.com/2026/07/20/m... It goes back from IDE land to a more vim-like (i.e. barebones) setup.

My coding setup now includes local LLMs but no more permission prompts

My journey to optimise my agentic coding setup has now led me to consider running an LLM locally and removing all permission prompts. Even though I don’t check every action of the agent anymore, I fee...

Question scoped to software in physics: Do you currently use PPC64LE architecture hardware for anything in your scientific workflow and is it important to you to have binary builds of software for that machine? Are there high impact examples that you can think of? Or is everything x64 or aarch64?

Two weeks ago, I posted that Python 3.14 was the fastest available/usable Python in @conda-forge.org.To keep new releases as quickly usable as possible, I'm reviewing this week what we did in this release and what we can already do to make Python 3.15 even faster: uwekorn.com/2025/12/15/p...

Learnings from the Python 3.14 migration

Python 3.14 Availability on conda-forge

Some stats from core dev @hauntsaninja.bsky.social showing Python 3.14 had more usable packages on day 1 than other recent releases. New releases of #cibuildwheel adding 3.14 as optional and then default also helped. discuss.python.org/t/stats-on-p... #Python #Python314 #wheels #stats #PyPI

Week 41 this year was the week of the Python 3.14 release and also the last one I wrote a report on my @conda-forge.org activities: uwekorn.com/2025/10/20/w...

2025-41: A week in conda-forge

While I was at @pydataparis.bsky.social , I did not spend much time on @conda-forge.org, but in that week, at least some important milestones happened for the Python 3.14 migration, e.g. unblocking everything that depends on pandas. More details can be found in my report: uwekorn.com/2025/10/16/w...

2025-40: A week in conda-forge

Python 3.14 has been released two days ago. At the same time, we also uploaded a build of it to @conda-forge.org and about 40% of Python version dependent (mostly those with compiled code) were immediately available. See conda-forge.org/blog/2025/10...

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.

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 😂
