my goals for December, what are yours?

Lovely when your TO-DOs and your Slack messages line up to form your birthday date. 🥲

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

Yes, half the internet is down, which is problematic. But all I'm worrying about TBH is that I might break my @duolingoverde.bsky.social streak...

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.

Since I'm working more with #python lately, I wanted to have a clean linting/formatting setup. Here's what I have in my settings.json in @vscode.dev / Cursor (big fan of ruff by Astral), anything I'm missing?

That first cup of coffee back home after a trip just hits different. ☕️

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! 🙌🏻

Finally, I no longer only have the case at home. Curious how this'll hold up. The phone is indeed quite orange, but upon first impression, I really like it.

🎓 Reasoning models have been one of the biggest innovations in LLMs in the past years. In this video, we take a look at: 🧐 how they work 🤔 how they differ from regular LLMs 🚅 how they are trained 🤯 how to get the most out of them youtu.be/lyEZG3Y614o

I'm really looking forward to this! It'll be purely coding-focused and it includes my favorite trick that is (at least to my knowledge) completely underused in the latest Xcode releases! Also....it's always worth joining for the community aspect! Who's in? 🙋

Looking forward to showing how to "Add video calling into an app in just 30 minutes" for the @revenuecat.com #shipaton2025 livestream. We're using #SwiftUI and doing some nice Liquid Glass animations while we're doing it. Join in just under 2h to take a look and follow-along!

I want to start a new weekly series here called #ToolTipTuesday. I've been doing that for a while on Instagram and TikTok, but wanted to move it here as well. For the first post, I'm covering the great UX site lawsofux.com 🧵 (1/11)

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.

AI is evolving fast, and one of the most interesting things lately has been MCP servers.🤗 But what is the Model Context Protocol that @anthropic.com pioneered and is becoming an industry standard quickly?🤔 Learn about the basics and building a simple server! youtu.be/Dkmfvfr1L4I

Want to reach more than 1 BILLION new users with your web apps?? 🤯 Ensure that #Accessibility is respected throughout the user experience. In this video, I'm going over 5 easy-to-follow tips. What sounds like a bonus is essential for a large user group! youtu.be/5oKRcNifVvE

Last night was really clear sky and I was able to snap this picture out of my window. Not using a tripod, only with my phone. Which - I think - is just incredible.

Perfect way to start 2 weeks of PTO. Kiddo at a sleepover and getting up early for a morning ride! 🚴

Building a popular platform like Twitch requires a lot of thought and features. In my latest video (which takes “just” ~5h 🤯), we take on this journey. Follow along for a fully-functioning livestreaming + chat implementation with @clerk.com and @supabase.com . (Video + Repo in 🧵)

What’s a daily routine that you’re sticking to, that has a positive impact?

I'm pretty sure which of these drivers knows the fastest route to the finish line! #TourDeFrance2025

A while ago, I helped to build a few @firebase.com extensions. They are an underused tool that can be incredibly helpful. Learn to avoid building a custom server in a chat app using iOS and #SwiftUI (same principles apply to all other platforms). youtu.be/ajlNzE6d9Hg

Just very innocently leaving my morning coffee here. ☕️ Have a great day, everybody! 😇

I really love Strava, but for this one, I need to call the design police! 👮

Just a reminder: this is how to properly set up mail and password input in #SwiftUI (Am I missing something useful here?)

I'm in the process of rebuilding my website + blog with @astro.build. Does anybody have recommendations for a good analytics provider (happy to be paying if great)? Requirements: privacy-focused, easy-to-integrate. Bonus points: also available for mobile

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.

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.

😴 If you think raw text-based chat applications are boring, say no more: It's easier than ever to add voice capabilities to our apps. In this video, I'll explore the integration of @elevenlabs.io into a @nextjs.org application to read AI-generated chat summaries. 📣 youtu.be/vfsHBBatmfo

A lot of people are trying out vibe coding, but how much skill is really needed to get a fully working app? 🤔 We'll explore by building the same app on different levels to see the impact has - on the app that is built, but also on the code...🧑‍💻 (Link to full video in 🧵)

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? 🤔

You may not like it, but this is what peak male parenting looks like.

It's crazy how much refreshed I feel when I have had an active weekend, spending time outside, and eating healthy.🌿 Also, had a lovely trip to Amsterdam last week to see my colleagues and looking forward to a more quiet week back home, with a clear focus.🧘🏼

Leaving for Amsterdam to meet up with my colleagues from Stream. (Taken with the Spectre app)

In my latest video, we take a @nextjs.org chat application and add automatic summaries of unread messages on top!🤯 I love adding useful features to apps with the power of AI and here we'll use a locally running LLM, specifically a Gemma model from Google DeepMind!😍 Link in 🧵

Finished this banger from Christian Stöcker ("The Men Who Burn the World"). The details of how certain industries (e.g. oil, gas) strategically influence political and social discourse are fascinating. Ever so current with recent claims from Germany's new Business Secretary...

When you miss most of the #GoogleIO keynote due to parental duties, and THIS is the overview. Like....there's so much! Not cool, Google, not cool! 🤯

That first run back home after traveling hits different, especially with weather like this…

It's incredible what a single person can build using free services! 🥳 In this example I've built a chat app using @nextjs.org (and Stream Chat), integrating AI summaries (powered by a local @googledevs.bsky.social Gemma model) and audio summaries with @elevenlabs.io. This is so cool!🤩

Made the most of a day off with lovely weather! 🏃☀️

May is approaching very fast, and I can’t wait to travel to wonderful Macedonia to be speaking at iOSKonf! 🇲🇰 The talk will cover how to build our own version of Apple Intelligence, completely with open source technologies! 🤩 I’m already very excited, who’s joining? ✌️

This was a daring, yet fun experience.🤩 Deven (Flutter DGE) gave me 3 UI challenges to solve in @flutter.dev. It's been a looooong time since I've written code in it, but it was a lot of fun!🥳 See how I did and how Deven encouraged (roasted) me along the way!😇 youtu.be/-AUHdhwSuqw

Finally found some time to continue working on my innocent indie Darts app. I optimized some database loading and a ONE-LINE code change took execution time of a query from: 165 seconds -> 0.02 seconds 🤯 Can you guess what kind of change that was?🤔

Am I doing this meme thing correctly? 🤔 #vibecoding

In this week's edition of #FundamentalsFriday we cover the basics of testing. Listen up all vibe coders and learn why it's crucial for building robust software. We cover types of tests, the testing pyramid, and touches basics of TDD. Everybody loves testing, right? RIGHT???😇

Starting the week the right way.

Another edition of #CSSSaturday. This time we're continuing the topic of last week: CSS selectors. We cover topics like child and descendant elements, pseudo classes, and pseudo elements. What's your favorite selector?🤔 (I'm definitely a ::before guy)

Slow weekend mornings with time to read are fantastic. I’m surprise it even took me a week to finish this new book from @tomhillenbrand.bsky.social. Tech thrillers are such a great genre and this one only confirms that.

This week's edition of #FundamentalsFriday covers version control and git basics!🎛️ It's a topic that might not be crazy popular but will simplify your career in tech tremendously. Learn it as early as possible and benefit from it forever!🎓 (You can even ship on fridays then)
