Just used @playwright.dev MCP Server to automate a full form submission — including image upload — with a single markdown prompt 🤯
No scripts. No selectors. Just natural language in VS Code.

📕 Last month, I published my first book. Algorithms don't like me talking about it, but if you could repost this I'd be immensely grateful! Even if you don't care about my writing, someone in your circle might.
But if you like atmospheric, highly-quotable stories, take a look👇

100% code coverage? No!
100% feature coverage? Yes!
Do not blindly chase metrics only because they are easy to measure.
Instead ask yourself: What do we need to deploy with confidence doing as minimal manual testing as possible?
Do whatever leads you there!

There are few things as beneficial to your career as clear, concise communication. Too often, people say too much in the belief that quantity makes them seem smarter or more important. Get to the point and people will respect you more.

A bunch of people reached out wanting to learn more about my Pocket clone and how to get updates. So, I set up a website. I had to go with intentional misspelling to get a domain name, but here it is:

Just set up GitHub’s new MCP server, no Docker, no keys, super easy
Then used Agent Mode in VS Code to:
🧠 Propose a website change
🛠️ Turn it into a GitHub issue
🤖 Assign it to Copilot
The future of dev is here.

OK, Bluesky. Time for an early preview. (X hasn't seen this yet)
I've shipped a 9-lesson tutorial on the Model Context Protocol - the USB-C of AI.
It'll take you from "WTF is MCP" to shipping your own servers to the world.
And, it's free. Check it out:

Can't recommend it enough! I started my OSS adventures a lifetime ago with Google Summer of Code creating a Boost C++ library. I had zero Open Source experience, and it was fantastic to do the first steps with the program structure and a mentor guiding and encouraging me. Don't be afraid and apply!

TIL about a new `parseInt` quirk.
I always thought it simply returns `NaN` when it can't parse a value, but as it turns out, if a value starts with a code unit representing a number it parses it until it doesn't know what to do anymore. 😲
