Enter AI

One thing worth mentioning here.

This version is the first developed with the extensive assistance of AI (Claude Code). All the generated code, though, is meticulously reviewed and corrected by me (still human). It often takes numerous iterations — planning, refining, re-planning, implementing and reimplementing — but all in all, I’m very positive about the results of this collaboration. It has immensely accelerated the development, allowing me to build much more feature-rich implementations without getting bogged down in the increasingly more complex internal machinery: just have a look at the sheer volume of changes since the last release.

Breaking change

For the February break, we once again embarked on our annual pilgrimage to the slopes: this year’s choice fell on the French La Plagne.

Below, you’ll find a short 4K video showcasing a week of tumbling, face-planting (nah…), and occasionally even snowboarding, plus a handful of photos that prove we did more than just lie in the snow contemplating our life choices.

LongeviumPredicting your future by VO₂max

Post image

I’ve decided to launch a dedicated series, which I called Longevium. There I’ll be sharing my insights and personal achievements in the realms of health, vitality, and longevity. Subscribe here!

Today, let’s talk about a rather intriguing metric known as VO₂max, also known as the maximal oxygen uptake. Modern physiology treats VO₂max as the gold standard for measuring physical fitness of a person.

And here’s where it gets really interesting: if you know your VO₂max today, you can predict your fitness level 10, 20, 30 etc. years from now. Just take a look at this chart:

LongeviumMaximizing lean body mass: my results so far

Post image

Are there too many “Comentario” posts in my blog?

Let’s change the subject for a moment. My New Year’s resolution for this year (what the Dutch call nieuwjaarsvoornemens) was to lose weight — specifically, to reduce my visceral fat percentage while maintaining muscle mass.

As you can see in the photo, the results speak for themselves. In numbers, I’ve gone from 87 kg to 72 kg (-15 kg or -33 lb) in body mass, and my visceral fat percentage has dropped from 13% to 7%.

I’m thrilled with the progress (also visible in the photo) — more details below.
