The ElixirConf 2025 videos are already published to YouTube! 🔥 youtube.com/playlist?list=…
The Expert Language Server is live: github.com/elixir-lang/ex… - nightly builds available for alpha testing and contributors. Thank you to @flydotio, @_tauspace_, and @River for sponsoring the development so far!
AI demonstrates the sunk-cost fallacy perfectly: Just one more "this doesn't work!" prompt, you think, and it'll fix it!! But often it won't, and now you've wasted 30 minutes begging that you could have spent learning how to actually fucking do it yourself.
Hello Alchemists! Let's drink some elixir at the September 16th meeting organized by PDQ meetup.com/bucharest-elix…
We rewrote the Ghostty GTK application from scratch and verified every feature with Valgrind along the way. Here's a reflection, plus notes about memory safety and Zig from a complex, real world codebase used by many, many thousands all day everyday. mitchellh.com/writing/ghostt…
@svpino When I was at BMW I worked at autonomous driving. People were joking that this makes no sense. You see BMW‘s slogan is „Freude am Fahren“ (the joy of driving), so why are we taking it away? There is no joy if you don‘t drive yourself? The thing is, not all driving is fun. The…
I've been writing code since 1994. I've done it in a dozen different programming languages, and 90% of the time, I haven't gotten paid for it. I write code because I love writing code first and foremost. The pay has always been a nice byproduct. Yes, the money is nice, but I…
My conversation with Jony Ive yesterday at @stripe sessions.
I like this mental model in how to think about engineering (including software engineering). It is a combination of building stuff for production, crafting, commercial use cases and science. From the book Software Architecture by Mary Shaw and David Garlan
Not a month goes by where I don't remind myself of this fundamental truth: There is no speed limit. It doesn't just apply to learning, but also to doing. Everything can be done faster, if you judo the problems, and decide to see it through. sive.rs/kimo
there is literally no universe that this is true 10k lines and its not bug filled crap? ok Lex Luthor, its time to step away from the keys
@svpino One pattern I catch myself doing sometimes is to vibe code a feature until it works. After that, I spend a lot of time refactoring the code to be maintainable, reusable and beautiful. The thing is refactoring is often easier when the functionality is working.
Phoenix LiveView v1.1 is out: colocated JS, portals, improved change tracking, faster tests and more! Read the announcement: phoenixframework.org/blog/phoenix-l…

The industry seems to be waking up from that fever dream, though. People are finally realizing that vibe coding makes for great prototypes and awful software. They’re waking up on the importance of fundamentals in a world where typing’s not a problem anymore.
I think LLMs are a technological marvel and I hold the utmost respect for the people who created them. I love that I can be a composer and an architect now. But I hate what marketing budgets and hype men have turned LLMs into.
You’d think it’s the execs, but no. I was disappointed in my fellow devs who threw all principles out the window for the sake of vibe coding. Speed, speed, speed. How do we turn programming into an assembly line?
Been a bit burned out of programming in general. It feels like everyone’s lost their minds with AI and is focusing on speed to the detriment of everything else. Started painting miniatures to feel like a craftsman again.
I know when you're vibe coding. I shouldn't have to care about this. Whether you wrote your code by hand, copied it from a forum, prompted an LLM, or ran a simulation where monkeys are given infinite time to produce the solution. Wrote my first article in months about this.
3 years ago, I tried to explain the magic of pattern matching and function overloading in Elixir to Prime. I didn’t do a great job. Now he’s explaining them to me. He’s doing an incredible job.
