🤔 I keep complaining about French paperwork but today I discovered US W8-BEN-E form.

Why do humans hate each other so much that they throw forms like this at one another?

I am starting to enjoy #Gemini ad-hoc generated games – with gesture detection etc… – more than my kids do 😄
A child sitting at a wooden table raises their hand excitedly while looking at a laptop. The laptop screen shows a split view with a Gemini conversation on the left and a brightly colored green game or animation on the right. The scene is indoors with soft lighting and a curtain in the background.

🎉 10th #NgPolandConf and 1st #AIPolandConf wrapped up! Sharp!

🙏 What an audience — I genuinely learned a lot from the hallway chats.

🙌 Always a pleasure to cook stuff on stage with
@rainerhahnekamp.bsky.social !

😱 For the first time… my new nemesis @butcherjs.dev hijacked my slot

Great to see the growing interest in #testing — I had a really nice group at yesterday’s workshop with real passion and sharp questions👌

And now #NgPolandConf kicks off with the #Angular Team announcing v21 release tomorrow with Vitest support.
A presenter stands at the front of a classroom, gesturing with raised hands while speaking to a group of attendees seated at desks with laptops. A large screen displays the slide “How to evaluate?” on a purple background. The room has floor-to-ceiling windows on one side and a whiteboard with diagrams on the other. The participants are focused on the talk, with some typing or taking notes. 3 presenters stand on a stage with large projected slides behind them. One is speaking at a curved white podium with a laptop covered in stickers, while the other stands slightly behind and to the side. Metallic balloon numbers are floating at the left. The stage lighting is pink and purple, giving the scene a conference-talk atmosphere

🤔 What if there were a conference without talks? Just hanging out with OSS maintainers & builders, seeing what they’re working on, and learning cool stuff by actually talking to people.

🤯 What if hallway track turned into the whole event!

💡 @tannerlinsley.com is exploring it. Interested? ⬇️

🤖 Did you know you can bring your own agent to my Pragmatic #Angular #Testing workshop?

Type "/next-hint" and it’ll whisper the recipe when you burn the sauce 😉

Have a nice weekend and see you on Monday at #NgPolandConf 👋

A split-screen screenshot of a code editor. On the left, a TypeScript test file (recipe-search.browser.spec.ts) shows a describe block, a todo test, and an unfinished mountRecipeSearch async function. On the right, a hint panel displays a highlighted purple box containing guidance: seed a fake repository with two recipe entries before mounting, and configure TestBed with provideRecipeRepositoryFake() inside mountRecipeSearch before calling createComponent()

I was checking something on my #Angular #Testing Cookbook's glossary cookbook.marmicode.io/angular/test...

I definitely prefer rereading my writing then my code. 😅

Karma is out of the pantry. 👋

Get ready for @vitest.dev & Browser Mode with #Angular 21

✨ New #testing cookbook chapter explaining why we’re back to the browser — and what actually separates:

👾 emulation,
🌓 "partial" browser mode,
🎭 & "full" browser mode.

⚡️ One of the most exciting things in #Angular 21 is @vitest.dev support — especially Browser Mode.

🥘 Fresh off the cutting board, I’ve cooked up a starter so you can taste it yourself 👨🏻‍🍳

🤔 Probably the first time Browser Mode runs on @stackblitz.com

Spent the last 4 months looking into LLM codegen quality and techniques of improving it for the new APIs (not in the training set).

Many learnings from the process, with the key one being: LLMs "preffer" good API design.

Codegen fails? Your human devs would be likelly confused as well!

🕹️Pick the sticker of the right #Angular state management solution.
Two smiling people stand by a round table covered with shiny hexagonal stickers featuring a purple design. They appear to be at a conference, with one wearing a badge labeled “NG-DE.” The setting has warm lighting, arched walls, and a casual atmosphere.

Many thanks to the lovely #ngdeconf crowd for the warm welcome and the enthusiasm about @testronaut!

Special thanks to @jeanmeche.com for being the perfect accomplice while @rainerhahnekamp.bsky.social and I cooked up some trouble together. 😉

Stay tuned 📻
Two speakers smile for a selfie on stage in front of a large, cheerful audience seated in rows inside a bright hall with arched walls and pink lighting. The crowd, many wearing conference badges, waves and makes peace signs toward the camera. A strong light beam shines from the back of the room, creating a radiant atmosphere.

Really cool and very transparent talk by @jens.ng on how the #Angular team is handling the planning and priorities etc...

Very inspiring!
A speaker presents on stage at a conference in a large hall with stone walls and arched openings. The slide projected behind them reads “Agenda” with four points: “01 The Angular Rhythm,” “02 Planning & Prioritizing,” “03 Feeding the Roadmap,” and “04 Your Opportunity.” The speaker is wearing a black T-shirt with the Angular logo. The podium shows the event name “Angular Conference NG DE.

✅ Just wrapped up the Pragmatic #Angular Testing workshop with @vitest.dev 4 — one of the most passionate groups I’ve seen.

Now, #ngdeconf is kicking off, and the energy’s already through the roof. 🚀
Group photo of enthusiastic workshop participants in a classroom setting. Around fifteen people are smiling and posing together, some raising their hands or giving thumbs-up. Laptops, drinks, and notebooks are on the tables, and everyone wears name badges on lanyards. The atmosphere is friendly and energetic. A large audience seated in a grand hall with arched ceilings and red lighting, attending a tech conference. A presentation screen at the front displays the title “Your Angular Education – Angular 18, Signals & DX Power,” with speaker photos and logos visible. The venue features stone walls, decorative carvings, and tall windows letting in natural light.
