A staggering statistic: "North American researchers were charged over US$2.27 billion by just two for-profit publishers. The Canadian research councils and the US National Science Foundation were allocated US$9.3 billion in that year." What are we doing?
We wrote the Strain on scientific publishing to highlight the problems of time & trust. With a fantastic group of co-authors, we present The Drain of Scientific Publishing:

Made a very simple python-based simulator for working on LCDs using u8g2 (embedded graphics lib). Not well tested & half vibe coded, but so far has been useful and saved a lot of time when it comes to playing around with fonts, spacing, etc. github.com/colinoflynn/... #embeddedguis #u8g2

Almost 13 years ago we were lucky enough to adopt Luna. Sadly our time to say goodbye is near, but for now we're giving her the ultimate dog days while we still can. To keep the "sad scrolling" all in one place I'll use this thread for photos this week, starting with a cart trip to a little park.

In 2020 I started a pandemic project of writing down lessons learned building @newae.com using a kind of partially-OSHW partially-commercial and no-VC model. This has spun into a book proposal, I've now got a landing page at colinoflynn.com/making-it-sm... as I will be releasing more from this!
