Hey Elixir friends! :) Hologram v0.10 is out, now with a real event system. To show it off, I rebuilt Space Invaders in pure Elixir, running in the browser with no game engine. There's a new server-side middleware layer too. hologram.page/blog/hologra...

James Harton is doing something interesting. NBPR is a tool for removing a lot of the annoying bits of customizing a Nerves system. Namely buildroot and kernel builds. github.com/jimsynz/nbpr #elixirlang

"Hot" take: in Germany landlords are required to ensure proper heating, but I‘d say proper cooling should be mandatory as well. One problem is that many Germans are too stubborn to accept air conditioning.

btw Ecto version 3.14 is out and has UUIDv7 support! #elixirlang

🚨 Please update "decimal" 🚨 A *single* calculation like: Decimal.new("1e1_000_000_000") |> Decimal.add(1) will OOM your application. Poof. Adios. Auf Wiedersehen. cna.erlef.org/cves/CVE-202...

If you’re running #Phoenix Channels (or LiveView) and have the LongPoll option enabled in your endpoint (default since 1.7.11), it’s time to do an update: github.com/phoenixframe... Thank you @peterullrich.com for finding and disclosing this issue!

Watching an @elixirconf.bsky.social talk by @steffend.me and saw my name as a contributor to Phoenix! That's what I love about open source. You can contribute to tools you actually use and love, and become part of something bigger than yourself :) #ElixirLang

The 5 vulnerabilities I found in Bandit were fixed and released today. Please go upgrade bandit ASAP. Thanks to @mtrudel.bsky.social for fixing them so quickly and to @maennchen.dev for managing the process 🙏 #ElixirLang cna.erlef.org/cves/

Oh, I almost missed that the ElixirConf EU photo gallery is out. Now you can play the "who is wearing a shirt Lars made while presenting" game that I invented. Was 3 for 3 for the first bit at the very least. Some lovely photos in there. codesync.pixieset.com/elixirconfeu... #elixirlang

Thanks to everyone that joined me for my first ever conference talk last Thursday at @elixirconf.bsky.social. It was a lot of fun! Remember to try the #Phoenix #LiveView 1.2.0 release candidate and report any issues. I'm also happy to hear if everything works just fine for you :)

After some deliberation, I finally decided to make www.TestingLiveView.com free! I still think it's an amazing resource, but my focus is elsewhere now. So, I wanted to make it a free resource for the community. #ElixirLang

Since switching to Linux on my MacBook, I've been running Discord and some other apps as Chrome Web apps. It's nice that you can easily wrap any page into its own launcher icon. What's not so nice is that all apps' audio streams just end up as "Chromium" in the system.

Last time I visited my parents, my father opened up a YouTube video of a "doctor" talking about medication you should not take if you’re aged above 60. I immediately had a weird feeling about it and after looking at it for a while I noticed a YouTube play button with clearly AI generated text on it.

At the beginning of February I used a Sunday afternoon to make some space on my MacBook's internal drive to install #Asahi Linux as a daily driver. Apart from some minor annoyances it's working quite well.

Today I woke up to my LiveView app on fly.io being completely broken as any WebSocket connections were unable to get established. No deployment, no code change. Since it’s an colder codebase, longpoll fallback was not enabled. Works now with long polling, but websockets still don’t 🤷🏻‍♂️

My new years resolution included finally building a blog and writing articles. Here is the first one: kevinschweikert.de/posts/build-...

I was thinking since Goatmire Elixir turned out pretty good I should maybe do another one. 30th of Sep - 2nd of Oct this year. We have a list to notify you about the progress and when tickets drop, getting on that list also helps indicate interest. www.goatmire.com #elixirlang #goatmire
