software innovation generally goes from cool experimental technology that proves the feasibility of something but is kind of janky to still janky technology that also cuts out most of what made the former cool and is also all corporate and for profit

I ended up removing AAAA pointer from DNS and letting the website sit broken for another day or so.

After the most recent renewal attempt, I was able to get a new certificate.

I have learned that certbot keeps logs in /var/log/letsencrypt/letsencrypt.log
Looking at this log file could have saved me a lot of effort.

My website flamy.ca is up and running now.

My website was out for a few days because of a problem with renewing let'sencrypt certs.

My host on has been having some issues with IPv6 addresses -- I have a really old config and sometimes IPv6 address disappears.

When certbot is listening for cert renewal it is not possible to select an address to listen to, so the certbot was unable to listen properly on ipv6 address until I ran out of renewal attempts.

46: Mountains

The layers keep track of a up/down direction for changing the height. They add noise to it, but also try to flatten it out over time. I like how smooth this makes them. #tic80

Strongly recommend Signals to Danger podcast if you’re interested in engineering disasters & postmortems.

The presenter is a railwayman and gives an excellent level of detail and deep-dive into the operation and procedures of the UK rail network across the years in examination of many significant rail accidents. A great one for long trips and even background listening if you want to. The most recent episode, Quintinshill 1915, dissects the deadliest accident in UK rail history with scientific but sympathetic rigour. It’s about as graphic as any episodes get.
I particularly appreciate the way Daniel Fox is scrupulous about detailing the exact procedures that should have been followed, with clarifying examples for non-rail experts, how they were contravened, and how it fits into the broader safety management system of the rail network.
It’s definitely for nerdy folks but very well done for a one-person operation.

there are literally activists out there who think everyone should read theory but can't be bothered to learn how to move off Facebook, Instagram & Twitter, which is VASTLY easier.

I love this video showcasing some unconventional uses for #inkscape ... if you're not familiar with his channel, you should really check it out. My fav for inkscape tutorials!

I've been doing some 3D modeling, designing another spotlight.

Here are the few things I learned for this project:

- When modeling shells use all of the existing parts (vitamins) to see how parts fit together. This saves a lot of filament.

- Create rough models for parts I don't have, to see how they would fit

- (more specific to openscad) Use 2d shapes and extrude them

- 2d polygons are flexible, but time consuming to design. It's ok to get started by combining squares and circles

I’m building another LED light from stuff I have lying around. I’m reusing heat sink from an old server.

I tapped the screws for the COB. I ended up breaking a tap, but it was at the very last hole, so i was able to finish this part of the project.

This is 50W light so it will need some active cooling. I ran it like this for a bit and the heatsink reached 55C
