In case you missed it, I was recently on the Changelog podcast to discuss npm's security woes. We talked about the 2025 attacks, some simple solutions that could help, why a competitor registry hasn't emerged, and more.

Follow up from @vlt.sh regarding my appearance on the Changelog. A new registry is in the works.
Notably, I actually started @vlt.sh to solve a lot of what you've highlighted on this pod. For the record, yes, we ARE building registry software. It's unfortunately taken longer then we'd like because but it's coming.

I was recently on the Changelog podcast to talk about npm's security issues, what can be done, and why the npm registry is unique amongst programming language source code registries.
💥 New Changelog interview! changelog.fm/674
Changelog Interviews #674
As the creator and long-time maintainer of ESLint, Nicholas Zakas is well-positioned to criticize GitHub's recent response to npm's insecurity. He found the response insufficient, and has other ideas on how GitHub could secure npm better. On this episode, Nicholas details these ideas, paints a bleak picture of npm alte...

As developers no longer need to code, there will be further changes to how software is developed. The tools we use, the size of the team, and the skills needed to succeed will change. Hand-coding may be considered too risky in certain industries. Read more:

Another gem from Gemini 3 Pro's thinking:
> I'm remembering that I keep forgetting the `isRegexp` function. It's frustrating to keep overlooking it; I'll need to make sure to include it from now on.

I spent some time over the holidays imagining what software engineering would look like in 5-10 years. As humans write less and less code, where exactly do we end up? I wrote up my thoughts in this post.

I am endlessly amused by some of the thinking I see in Copilot. A gem from today: "I'm starting to think the function name is fairly straightforward: add_url." 😂

I don't believe the "it's coming for all programming jobs" story of AI.
AI is like a musical instrument, in that it's a creative tool and it's the people who use the tool that determine the output. A piano is capable of beautiful music with a skilled pianist. With me, you get chopsticks.

Remember, just because code works doesn't mean it's maintainable.
Copilot successfully implemented Redis caching for Bredbox, but the code is too difficult to follow. So, I'm redesigning it and putting Copilot to work implementing the new design.

Figured out why my newsletter ended up in spam. I thought I was sending from a dedicated email previously, but it appears I wasn't. It was using my personal email. This edition was sent from the dedicated email and messed things up.
Thanks to everyone for letting me know and marking as "not spam."

I was surprised that Upstash Redis didn't have an official local development server, so I and GitHub Copilot teamed up to create one.

You know how caching strategy design sucked before AI?
It still sucks. Only now you can endlessly debate with an LLM instead of another person.

Gemini 3 Flash is my new favorite 0.33x model for Copilot. Just the right amount of action vs. thinking, follows AGENTS.md well, finds and fixes its own mistakes.
