The process is called enshittification, and Norway did a PSA on it.

Unironically added this to a prompt before: “how would @danabra.mov write this code?” It works 😅

A good reminder. Any process that can be done with old school mechanical static deterministic code instead of LLMs should be done like that.
I've been experimenting with different approaches to build a system where humans and agents can ship fast safely. Think I've found something that works – custom linters.

This is the most important video I've ever made.
In this, I explore the negative and positive mental health effects of AI coding, with data and expert commentary.

Indeed, so always write it as simple for the reader to understand. Or you know, for yourself in 2 weeks.
Reminder that reading code written by another is an order of magnitude harder than writing it yourself.

It just dawned on me that "firm"ware is someplace between software and hardware.

Wow this is really nice. It’s a feature I’ve been missing that I used at my first programming job where they used SVN lol.

If everyone uses a release cooldown, do comprised packages get noticed in time? Or is it like the joke you hear during a safari: “you don’t need to outrun the lion, you just need to outrun your friend”?

The topic of skills atrophy has been running through my mind quite a bit. Delegating cognitive tasks to an AI system could mean over time you lose some of those abilities yourself. Similarly to how you need to keep training a muscle or a sport: use it or lose it.
But is this always bad per se?
But is this always bad per se?
The idea that technology, like AI, deskills us is not a surprise. I learned cursive at school, my father learned how to use a slide rule. Neither skill is widely mourned.
What is important is whether we will make deliberate choices about what skills to keep & which they will be.

Yesterday I had my iPhone battery replaced after some years. I had forgotten what a great feeling it is to only have to charge once per day. It lessens the desire to replace this 13 pro, which is otherwise working perfectly fine still 👌

From a token efficiency perspective I don’t fully follow why agent skills would be more efficient than MCP. Doesn’t MCP expose a short description of available tools in the same way skill markdown files have some meta details in frontmatter?

I have always been the kind of developer who only cared about outcomes. Give me the tool, the framework, the head start. I just want my website.
A totally different kind of developer exists who cares about the *craft*. Getting that function just right. Those devs are in pain right now.

My girlfriend and I are taking Spanish lessons. We got a traditional book and studying goes well.
So of course I’m working on a tool to optimize learning. Using spaced repetition algorithms, flash cards and good quality spoken output. Pretty much Anki, but more specialised.

Due to technical limitations there can't be two usb 3 ports. Awkward, but fine. But then the placement is a bit counter intuitive.
When both ports are in use, it's probably most likely the port more to the back of the device is used for charging, keeping the faster port occupied.

Scraping bots are getting good. They can pass CloudFlare challenges. We’ve been fighting a 40k “random” ip botnet for a couple of days now. CF does mark them as “somewhat odd” with a lower bot score though. That helps.

We ran into a memory leak in a Node service due to a misunderstanding of Reselect’s createSelector memoization. Might be worth writing up, or is that too dry? 🤔

Can’t wait to try it out! 👌
We've got some updates on TypeScript 7! The new native port
- can type-check any project
- supports --build and --incremental
- has rich editor features implemented
- is still 10x faster
and is ready for you to try today!

👀 Future of JS
This underrated upcoming JS feature is super useful 🔥
Soon, you should be able to import JS code as a string!
This is super useful, in particular for docs sites!
Similar to Webpack raw loader, asset query ?raw etc, but available everywhere natively!
