Almost all my socials are geolessel but my blog/personal site has long been at geoffreylessel.com. I think I'd like to keep the full name as canonical for my writing and I could of course redirect/mirror the other domains to that as well.

I mentioned ADS-B signals in my ElixirConf talk about binaries and bitstrings. I first tried out SDR over 10 years ago but haven't gone back to it in a long time. I bet it's much better now; I'm considering trying again. I think it'd be cool to show the info of aircraft as they pass over my house.

Looks like the link in the og post 404s for me. This one works though! www.joekoski.com/blog/2025/09...
Livebook Examples from Advanced Functional Programming with Elixir
It feels a bit impolite to ask readers to download code and type mix commands just to run the examples. We have better tools now.

I’ll have some Build It With Phoenix stickers (builditwithphoenix.com) as well as some Wavepal (@wavepal.app) swag. I unfortunately don’t have any Symbolic.ai swag but I’d love to brag about the things we’re doing in the AI space!
