I wanted to announce a new blog article today.
My blog runs on @cloudflare.social Pages.
Good that I didn't.

You'd be mistaken if you thought pigeon droppings on the floor were just a random annoyance. Quite the opposite! They're a real-time heatmap showing you the probability of being hit by pigeon poop at any given spot.
And you thought all that statistics knowledge was useless!

One killer use case for AI agents is making sense of minified JavaScript files.
I just built a post-install script that monkey-patches a package I depend on. What would have easily taken me half a day was finished in under an hour.

Turns out my team and I are partially doing Angular ... again. Haven't touched the framework since v16. Feels like ages.

🛠️ If your team has issues to work through:
We do an exercise at offsites called Elephants, Tigers & Paper Tigers.
- Elephants are things that the group isn’t talking about but needs to
- Tigers are things threatening the team, risks
- Paper tigers are things that seem like risks, but aren’t

Getting a full afternoon of uninterrupted coding is so nice.
I don't get that often but today is one of those days. Feels great!

Sometimes programming just feels too much like Hänsel and Gretel.

Basic question but I can't figure it out. How are these two design patterns called?
In the first, the component structure is fixed, and behavior is controlled *only* through props serving as config.
In the second, an extension point via the children prop allows for more flexibility.

Don't sleep on @playwright.dev's test steps.
It took me 4 years to realize how much cleaner, readable, and debuggable my tests could be.
Named steps = better readability, clearer reporting, faster debugging.
Check out the before/after!

Some tools force you to learn a complicated API and require constant maintenance.
Other tools... just work, and that's why it's easy to overlook them.
@openfeature.dev is one of those tools.
Do I use it daily? Yes.
Do I ever have to think about it? No.

Finally moving all my pet projects off Travis CI. Not a fan of their expiring credits billing model.
But where to migrate?
- Circle CI
- GitHub Actions
- ...?
What’s your pick?

I was frustrated with the lack of clear advice on setting up copilot_instructions.md. Most guides are vague, or worse, generic AI slop that *hurts* Copilot's performance. So I experimented and found better ways to make Copilot *actually helpful*. 🧵

Crazy idea to utilize the webcam input. Mind-blowing.

Large Language Models (LLMs) with "reasoning" capabilities are super hyped, but new research from Apple shows their "thinking" is often an illusion. Beyond a certain complexity, they fail completely. Key points in the 🧵.

My learning for that day: the final solution was to use the render props pattern.
Kudos to @bhuynh.dev and @taranetz.com for pointing that out.
We can even take a step further by leveraging React's `isValidElement` function to support both render props and a standard child component.

I have a passive theory that the manner in which junior and senior devs leverage AI assistance for coding is fundamentally different: (1/?)
