Finished a half marathon in Azuqueca, Spain. Feeling much better than I felt at the Innsbruck Ultra last weekend. You can’t skip training if you want to run properly.

I am keeping the @kotlinweekly@kotlin.social AI free, and it is honestly my little moment of joy on Sunday morning: searching articles, updating my TODO list, checking announcements, and doing a bit of a write-up.

Could I automate all this with AI? Yes.

Would it make my life better, or provide more value to readers? Probably not.

I went this morning to the doctor for a medical recognition. He weighted me, and told me that my BMI says I am obese. He did a bit of theater, broke the paper and told me the BMI is bullshit.

I weight 80 kg, 174 centimeters. Right at the start of obesity. I run ultra marathons, go to the gym regularly and generally take the bike twice per day.

BMI just checks the relationship between weight and height. According to this, a body builder is probably morbidly obese.

Paced today a 10K in a small town near Munich. The atmosphere in little places is always fantastic.

Finished the first Spring half-marathon. Very out of shape after the winter break.

Started today a book I wanted to read for a while, and very appropriate for 2026.

Landed in Saigon. The new QR code to expedite immigration has, unsurprisingly, no effect in immigration time.

I also always underestimate the heat and humidity.

US and Chinese LLM companies reached the place they have by canibalising global knowledge , including copyright content.

They should be lenient if EU companies attempt the same.

If only we could have some laws to prevent this:

Today we went to take some pictures of the Sakura in Munich.

Finishing the Kotlin Weekly from an airport today

I have realised that LLMs (specifically Gemini) tend to do some things I don’t like at the start, like squashing commits when committing something new, or pushing to GitHub without my confirmation if it is using the gh cli. I have published some of the skills I am using when working with it:

Trying this Sunday the new JetBrains IDE (are agentic environments also called IDEs?)

Gemini CLI deprecated in favour of Antigravity CLI:

Ich habe die Deutschen überdeutscht.

The case against an imminent software developer apocalypse.

Since the advent of ChatGPT, the software developer population has grown between 18% and 50%, depending on.

One of the problems I find with skills in LLMs is that they are very scattered through documentation pages, GitHub repos, etc. I would like to have a repository where I can search them, and ideally install them directly via my CLI

I have published FindSkills.dev, a small pet project to collect skills with some search functionality:

The tickets for the Kyoto marathon are open.

In 2017, I paid ¥16,500.

Today, they cost ¥35,500.

Do I know any Senior Backend Engineer with Kotlin for a contracting role?

Proficiency with Kotlin and Coroutines, API design and development with REST or GraphQL

Open to travel to London or Berlin occasionally; EU, UK and EEA-based candidates.

"There Is No Antimemetics Division"" didn't resonate too much with me.

I think the error was to read the book BEFORE actually reading the short stories or watching the short SCP movies. I went down the rabbit hole of short horror movies, and they are awesome.

As much as I love Vietnam, some of the subtle authoritarian quirks still piss me off.

Last government rule: if you stay overnight at a friend’s place, you're required to register it through the government app. Sure, it’s mostly symbolic since it's virtually impossible to enforce, but it’s a telling example of the surveillance mindset you occasionally run into.

Gemini has unacceptable response times for simple things, despite paying 250 € per month.

I will be pacing for the second year in a row the Munich Marathon. Really glad to be a small part of the running community in Munich.

If you are based in Munich and want to get started as a Pacer in the running world, the Landshut orga team is looking for a pacer for the 10K á la 1:05 (6:30 min/kilometer).
