Pieter Levels (@levelsio) has a habit of confidently misreading data and treating anecdotes as evidence 🧵👇
This is what happens when you train your AI and your following base with skewed world views, dodgy studies and huge biases: they amplify your crooked narrative.
At least 85 people this year died from Spanish train accidents, and likely it will grow to 100 at the end of this day
Very tragic and this makes Spanish trains one of the most dangerous modes of transport now
~100x more dangerous than flying commercial
~40x more dangerous than non-Spanish trains
And every trip is nopw as dangerous as jumping from a plane and skydiving
Two highly deadly train accidents in one year, that's so extreme and unlikely that it makes it at as dangerous as flying one of the most deadly airlines in the world, the Nepalese Yeti Airlines that keeps crashing due to the mountainous terrain
Pretty exceptional in a bad way

Every chapter has an end. It's time to sunset StartupsBCN, the Slack community we started 11 years ago.
At its peak, it was the online place to be in Barcelona, with thousands of members and many communities, events, coworking spaces curating their people and their content in StartupsBCN. In the recent years, it petered out and died a long, slow death.
We could've done better, but we're grateful for everyone we've met through this community, the bonds it has created and... even families, in some cases!

Hay empresas que contratan a alguien para que intente entrar en ellas. Sin que lo sepa casi nadie del equipo, a veces por la red y a veces colándose en la oficina, para descubrir vulnerabilidades que ni ellas mismas conocían.
También conduce @tierradehackers , su podcast sobre ciberseguridad. En el nuevo episodio del podcast de MarsBased, junto a @lexrodba , nos cuenta en qué se diferencia el red teaming de una auditoría.
Y muchísimo más. Te aseguramos que de este episodio saldrás viendo la ciberseguridad de otra manera: youtu.be/IHNuqcwM9Qg
No es tan sencillo emitir en todas las plataformas, cada contenido necesita ser adaptado a su formato.
After 11 years, we’re closing Startups BCN.
We started it in October 2015 as a Slack to keep the conversation going between Startup Grind Barcelona events.
Activity faded after the pandemic. We looked for someone to take it over, but no realistic plan came in, so we decided to close it properly instead of letting it linger.
In the latest episode of Building MarsBased, our CEO @lexrodba tells the whole story and why it fits our “do less, but better” approach.
Thank you to everyone who was part of it: youtu.be/0FDLmtOcTJ4
Our latest newsletter is live, and if you’re not subscribed yet, this is a good one to start with.
The Tailwind and Shopify move is still one of the big conversations in frontend, and we share our take on it.
But the real highlight: we’ve open-sourced our entire React Native playbook, built from everything we’ve learned on our recent mobile projects.
You’ll also find why we think Rails is quietly winning the AI agent race, a few Claude Code tricks we actually use day to day, and a great talk by Matt Pocock on why PRs are the new bottleneck.
