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?☝️

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! 🙌🏻

It's been a while, but I finally got back to continuing the "AI for Good" specialization from @deeplearningai.bsky.social on Coursera. It's so much fun to explore more about how to leverage the incredible powers that we are given with AI and how we can use it for good things.

In today's edition of REALLY helpful AI code generation... I asked to create mock data for a project I'm working on, and it came up with this brilliant comment instead of really creating 25 entries into the array. Nice try!

It's subtle, but I really like the attention to detail here. When I put in a meeting with the title "Coffee chat" Google Meet will automatically populate it with this beautiful illustration. This is the kind of fun and playfulness that sets designs and UI apart.

Stefan Blos @stefanblos.com · 01/07/2025

I like the approach that @clerk.com is taking by adding a "Copy prompt" button to their Quickstart tutorials. It's interesting to see how companies are adopting the increased usage of LLMs in coding to improve the DX for them, and not only developers. Clever usage.

To my iOS (animation) #SwiftUI friends: I have a ScrollView that I want to animate to a position slowly (think of a gallery in an onboarding flow). Changing the duration (or the animation type) in the withAnimation call doesn't do anything. Is this not possible to change? 🤔
