Not that I have any amount of free time, but I'd love to learn the Lean programming language. Will read this new book, "The Proof in the Code" in the meantime www.quantabooks.org/books/the-pr...

The Proof in the Code - Quanta Books

The inside story of Lean, a computer program that answers the age-old question: How do you know if something is true?

Where’s the power lifting side of Bluesky ? 205lbs (93kg) front pause squats for 3 reps. Not long ago this was a 1 rep max without a pause. Consistency is key. Don’t skip leg day 🫡 🔥

Honestly love that in this day in age, Wikipedia has become the most dependable source of information because actual humans are involved in the editing and publishing process (well at least I hope they still are). Can't believe my teachers used to tell me it could never be trusted!

Today marks 2 incredible years at @harper.fast 🎉 I joined as a software engineer and now I lead Open Source Engineering (OSPO). Grateful for how much I've learned, and for the entire team that mentors and trusts me every single day. And the best part is I still get to write code!

I'm learning @atproto.com by implementing @standard.site for my @astro.build blog. Tonight I focussed on the architecture of atproto, explored its SDKs, and how standard.site factors into everything. I have a loose astro integration wired up too. This is fascinating tech!

Went outside and caught some brook trout in beaver dam ponds with my new tenkara rod. Love touching grass 🎣 ⛰️

Web personalization is a platform decision. Architecture determines data freshness, latency, operational complexity, crawler visibility, and cost at scale. We compared five common approaches and the tradeoffs behind each: www.harper.fast/resources/fi... #SoftwareArchitecture

I did some writing about @nodejs.org streams earlier this year that I think you will all enjoy. First article is about custom stream implementations, and the second is all about optimization. Enjoy ✨ 🚀 🐢 ethanarrowood.com/blog/buildin... ethanarrowood.com/blog/profili...

Sorry, I still haven’t left Spain yet. Hiked 16 miles in the 90°F heatwave today on Ruta del Cares. I’ll review your Node.js PRs soon, I promise.

AllTrails hike data imposed on an image of the canyon from the hike. Data says 16.15miles 4:32:00 time and 7,913ft
