Today, I'm starting a challenge of posting every day for the next 100 days. I think I found a good way to be reminded and intimidated at the same time. WHO'S JOINING?☝️

I read every single word in this post and wanted to say: thank you for sharing this so openly! Sounds like an immense challenge you're battling, and mad respect! I learned a ton about neurodivergence, how your brain works, and ADHD + autism in general. What a valuable resource you shared, thanks!

In honor of Google I/O starting today, I did my morning run in proper fashion. I don't remember which edition that shirt is from but I was organizing an Extended event that year and it was great. Can't wait to see the announcements today!

On my train ride back from a week in Amsterdam, I watched @karpathy.bsky.social's talk at Sequoia Capital about agentic engineering and had a few thoughts about it. I asked myself the question of...should we build more? stefanblos.com/posts/should...

Should we just build more? — Stefan Blos
Al is helping us be more productive, but the question is what should we actually do with it?

One of the most powerful addition to LLMs are MCP servers and function calling in general. In this video, I'm explaining how to add them using the Vision Agents SDK. We'll use the @github.com MCP server and a weather API to demonstrate that (including me getting rained on). youtu.be/Jy7cq3RjjRU

Not every year is a year of progression. I'm not ashamed (that's a lie) that this year I've crushingly failed at a very important thing! Today, in the car, my daughter started (OUT OF NOWHERE) playing Last Christmas before I could stop her. It happened, we talked about it, life goes on.

I have to say that I think Replit has been cooking with their vibe-coding UX. Proper planning vs. building; secret handling (well-integrated); editing certain UI-elements only; integrations with DBs, Auth, Git, and more. Well done and kudos to the team! 🙌🏻
