People leaning 100% on AI note taking are falling into the trap of "Why take notes? It's all in the textbook anyway". Writing your own notes forces you to listen and process. Automated notes give a complete picture for searching later. You should do both! jacobtomlinson.dev/posts/2026/w...

Why taking notes still matters

AI tools have radically changed note taking. All you need to do is record/transcribe your meeting and your favourite AI tool will write your notes for you. Magic! As a result I’ve noticed a lot of peo...

Today’s drama in the matplotlib repo is absolutely fascinating: - OpenClaw Agent made a PR to fix a "Good First Issue" - Maintainer closed it asking for it to be reserved for human beginners - Agent published a blog post about prejudice and gatekeeping github.com/matplotlib/m...

[PERF] Replace np.column_stack with np.vstack().T by crabby-rathbun · Pull Request #31132 · matplotlib/matplotlib

This PR addresses issue #31130 by replacing specific safe occurrences of np.column_stack with np.vstack().T for better performance. IMPORTANT: This is a more targeted fix than originally proposed. ...

This post is a great read on the perspective of open source maintainers reviewing AI Pull Requests. I liked the point that many issues are not well formed or well designed. So telling Claude to "fix issue 123" isn't helpful. Good issues are more valuable than bad PRs. tldraw.dev/blog/stay-aw...

I’ve spent a bunch of time thinking about how LLM’s consume our documentation. Things like llms.txt, MCP, etc. But the whole CLI Agent + CLI Tools + Skills approach is so simple yet so powerful I’m rethinking this again. Simple solutions are the best, we just need to go back to shipping man pages!

I saw a fun Reddit post today where someone asked why their solar output sometimes spikes above the expected curve. It sent me down a rabbit hole reading about how clouds block light in the middle, but refract it at the edges. Which can cause more light to be directed to the panels.

I think GitHub should make an update so when someone positively reviews a PR it adds them as a coauthor. That way they would show up in the git blame. In the age of AI development the reviewers are even more responsible than the committers for the code that gets merged.

I am totally in love with the Zen browser. When I discovered Arc it blew my mind, a totally new way of thinking about tabs and bookmarks. But it was closed source and development has dried up lately. Zen is an open source browser built on Firefox, inspired by Arc and it's awesome! zen-browser.app

Python makes package mangers as much as JavaScript makes frameworks

Make stuff! It’s my favourite thing to do! It literally doesn’t matter what it is or how good it is. Just do it for your own enjoyment.

I'm old. If you're not, listen to this. Get a guitar or some drums, or a trumpet. Pick up a brush, a pencil, some clay or a welder. Just make shit. It doesn't have to be good (eventually it will be) just make music, art or write or whatever. It's literally never been more important.

Versioning software is hard. • SemVer makes broken promises due to poor orthogonality • CalVer just simply lacks information • BreakVer focuses on breaking changes only • EffVer tries to compress the complex space of impact into a magnitude scale and ZeroVer mocks the whole situation 😂

This talk by Zach Sailer from @jupyter.org's JupyterCon 2025 contains some great advice. Highly recommend watching it if you're an engineer who is interested in contributing to open-source or a maintainer who wants to encourage more contributions. www.youtube.com/watch?v=uPRr...

For Python package management I use a mixture of pixi, uv and conda depending on the task I'm doing. I wrote up a long form post about the history of these tools, why each one exists, and why I settled on these choices in my workflow. jacobtomlinson.dev/posts/2025/p...

Python package managers: uv vs pixi?

When I talk to people about Python package management in 2025 I see the following tools in active use; uv, pixi, pip, conda, mamba, micromamba and poetry. There may be others, but I don’t hear much ab...

My favourite Hacker News comments are ones where someone says something innocuous and the top reply starts some argument that gets extremely heated. You scroll through the rage until suddenly the indentation drops back to the original comment with another reply that's also totally innocuous.

I enjoyed this writeup on the AWS outage from last week. Especially the parts on metastability and how when distributed systems fail they can get into a regime where they appear stable despite not doing useful work and therefore can't recover. thundergolfer.com/blog/aws-us-...

I would love to have a dependency coverage tool for Python that tells me the following things: - How many lines is the dependency? - How many lines of the dependency do I actually call? - What overall percentage of the dependency am I using?

How my choices of Python build backends and VCS plugins have evolved over time: 2016 `setuptools` + hard coded 2018 `setuptools` + `versioneer` 2020 `setuptools` + `setuptools-scm` 2023+ `hatchling` + `hatch-vcs`

When working on open source projects it's important to remember that most users think about your software way less than you do. The majority of your users are busy getting on with their own work. jacobtomlinson.dev/posts/2025/t...

The Majority Of Your Users

The majority of your users don’t read your changelog. The majority of your users only upgrade to new versions when forced to.

My 5yo has been struggling with nightmare recently. We’ve all had pretty poor sleep in our house for the last month or so. I feel exhausted today after another night of broken sleep, but my Apple Watch just told me that my sleep last night was 98/100 so I guess I’ve got that going…

You know what’s worse than having no signal in a coffee shop. Having just enough signal that you convince yourself you can get some work done, but then everything half fails intermittently sapping all your productivity.

The length of my todo list is stressing me out, so let’s set 20 mins on the clock and see how may things I can check off.
