I made something new: an eslint plugin to validate your npm ecosystem lockfiles! It supports npm, pnpm, yarn, bun, and vlt, and it's already helped find a supply chain security attack vector inside a fortune 500 tech company. www.npmjs.com/package/esli...

Great read. LLMs give us the ability to solve our specific needs with software, like an extra pair of opposable thumbs. outofdesk.netlify.app/blog/perfect...

We have many names to describe personal tools. Malleable software speaks to how it behaves. Home-cooked software speaks to who makes it.

I’m all for using LLMs when it makes sense, but the walls of text are unnecessary where a few bullet points suffice.

My previous lead fell through, so...

Does anyone in Western Washington have an electric piano with weighted keys that they no longer use and would be willing to give away?

I have a ten year old ADHD kid whose heart is set on one for Christmas but it's not in our budget this year.

MSBuild tip: if you're working with binlogs, set the environment variable MSBuildLogPropertyTracking=15.

It enables logging of where each property was initially assigned from during evaluation and lights up more features in the binlog viewer.
