Every now and then I find an album I can listen to endlessly on repeat, and right now it’s Paul-Marie Barbier’s Solo on the Side. m.youtube.com/watch?v=Q4Lu...

Can you believe that back in the day the recommended solution was not just to shut it down and turn it back on again, but to actually drop the entire thing six inches onto a hard surface in the hope that loose senators would reseat themselves?

Wow, @observablehq.com's new Notebooks 2.0 seems really, really good. An offline editor app, a pleasantly-human-readable notebook format, and had no trouble integrating it into my website here: rreusser.github.io/notebooks/he...
Hello, Observable Notebooks 2.0!
Kicking the tires of Observable's new notebook tooling!

I'm in the phase of my programming career where I've figured out how to write a simple-enough recursive descent parser, and suddenly everything looks like a parsing problem.

Turn on the sound — this is how nearly every night sounds for me and my family. Imagine getting used to that, living, working, raising kids. A lesson the world didn’t learn from WW2: when you tolerate and appease evil, it grows stronger, and you won’t notice until it reaches your home.
Russia continues it ongoing campaign of terror against Ukrainian cities.

Expanded it to work across an array of satellite tiles and added soft shadows. Softening shadows around the azimuth is easy because you just average samples (here, 16), and along the altitude is even easier because the horizon algorithm gives enough information to simply do a smooth fade.

Obiymy Doschu have released “Vidrada”, our new album, passionately crafted in Kyiv for 7 years. I've never been more invested in a project, and will be proud of it for the rest of my life. All my love, dreams, hopes and worries in one record. ⬇️

Made a quick page for sharing/browsing Mapbox maps. Has a screenshot button, a style selector, a share link, and can add to homescreen, if that's your thing. E.g. an excellent boat wake 🚢: rreusser.github.io/maps/box-o-m...

If you write “Voight–Kampff” instead of “Voight-Kampff” you’re a LLM.

Happened to stay up late and catch Sam Watson (spoiler alert) setting two speed climbing world records last night! Made a quick plot of the world record progression, and if we can simply extrapolate this, then it looks reasonable to expect more. So fast. #climbing observablehq.com/@rreusser/sp...

A photo from a recent trip to Wadi Rum, Jordan. Still in absolute awe of the place. Absolutely excellent climbing, plenty of interesting fauna, and the people were extremely friendly (and confused about what's going on in the US). (full disclosure: photo has been slightly edited.)

Alright, fixed the ad hoc lighting computation for my terrain shading, I think. Always tricky to balance good appearance and good controllability. Try it live here: observablehq.com/@rreusser/li...

The sun rising over Thor Peak, Auyuittuq National Park, Canada. It's using line sweep horizon tracking to compute ambient occlusion and physically accurate shadows together with relief shading, all packed into an RGBA texture. Pretty happy with the scanline algorithm, but the shading needs work.

A more modest Trains and Trails run this week through Briones Regional Park. 14 miles and just over 3 hours from door to door. Already can't wait to go back. ☀️🏃♂️🐄 rreusser.github.io/trains-and-t... #running #trailrunning

I've put a lot of work into the template for my running blog site. Not looking for congratulations, just genuinely curious: if I took the time to clean up the rough edges and turn it into a proper authoring tool, is that a thing literally anyone would use/want? rreusser.github.io/trains-and-t...

New Trains and Trails! From Lagunitas, toward Point Reyes National Seashore, then back down the ridge to Stinson Beach. And a Dipsea. A pretty intense day by the end, but I'm going to call this the best route I've run in the Bay Area. Oh my gosh it was lovely. 🌲🥰🌲 rreusser.github.io/trains-and-t...
