I usually bike around #Berlin, but the last two times I used the #BVG, I’m pretty sure I saw the same guy “accidentally” bumping into women. Both times on the U2.
I think it was the same guy, and I think both times were on purpose.
But you could also argue they were accidents.

New post, about micromanagement and how I try to avoid it.

Also some anecdotes about storms and farms, and lots of analogies with farms and trees.

Have you been on either side of micromanagement? I’d love to hear your take

How you build the product is more motivating than the product itself on the long run.

Some thoughts about it.

Check out my post, and this time I am ranting.

This is my honest rant on PM content that lacks depth—and how to stay grounded while learning and growing in your craft.

Check out my new post, where I talk about 1 of first culture shocks I had after leaving academia and joining the product management world. + I address what does it mean to have an statistically significant experiment (the reason I go on the culture shock journey).

I don't understand why is YouTube Music censoring @rageagainst.bsky.social asking to click to acknowledge that the song may have references to "suicide or self-harm"

If I have a playlist running, it just stops playing and no control works whatsoever until I click on the disclaimer.

Hard to wrap my head around the fact that 1 in 5 voters in Germany think they will be better off if I would not live and work here.

🤡 they voted for the AFD for different reasons. At the end of the day, migration and foreigners is a big part of their agenda.

4 in 5 do want me here (or don't care)

In some Mexican news, there is the theory that Google maps changing the name of The Gulf of Mexico is part of the conspiracy of the broligarchy appeasing Trump.

Google has been adjusting its data to the country where it is shown for a looong time.

Google has become the de facto arbiter of national border placement, and it's basically trying to not piss anyone off.
