Build It With Phoenix | Phoenix and Elixir video courses
Video courses for the Elixir programming language and the Phoenix Framework.
builditwithphoenix.com
I haven't mentioned my #ElixirLang video course (on socials or to my email list that explicitly signed up for emails 🤦♂️) since March. That is terrible marketing. Thankfully I'm a much better teacher than I am a marketer!

I have been undecided on this point for a LOOONG time and I still can't decide. Inaction isn't working for mean anymore. So not I ask you: do you think I should make my bsky handle @geolessel.social, @geolessel.com, or @geoffreylessel.com?

I am fortunate to have been able to see the opera by my favorite composer (Debussy) from the Vienna Opera House a couple of days ago. It was amazing.

The first thing I did today was listen to my daughter's (artist name of Avenglow) new single, "little love notes + songs about you". I suggest you do as well! music.apple.com/us/album/lit...

Current status: @americanair.bsky.social won't let me change or cancel my flight for a partial refund or flight credit but is simultaneously willing to potentially offer me $200-$450 to take a different flight. 🤔

My favorite band is U2 and one of my favorite albums to listen to with good headphones in U2's Pop. There is so much ear candy all around. I feel like I hear something new every time I give it a listen.

Current idea I'm obsessing over: a coffee shop that outlaws computers and you have to check your phone in at the door.

It's been a while since I've payed attention to much social media. It has been too long since I've been to a good tech conference. What are some good #ElixirLang ones coming up? Any still accepting speaking proposals?

I'm spending my afternoon checking out the Ash Framework for #ElixirLang. I went through the Livebook tutorial (which was great!) and for some reason, on a new app, have hit a roadblock getting user authentication going.

Indiana Jones and the Great Circle is so good. It has been a looong time since a game with a narrative has hooked me this hard. I’m usually more of a factory or strategy or builder type of gamer but I can’t stop playing this.

This is a buy for me (esp. with the discount code)! TCP/UDP are at my current level of nerdery interest (VERY low level). I played with some UDP packet stuff in Elixir back in 2019 (relevant talk here: www.youtube.com/watch?v=7kg0...) but haven't really done much since.
