It is a spiral, not a circle. Software development, even without the current form of AI, will never return to its previous state.

There's an opportunity to try out @atmo.rsvp for the FP Stammtisch next week hosted by @runlevel0.me If you're in Munich and interested in #Functional #Programming #FP - give it a try! atmo.rsvp/p/j4nk.dev/e...

We make so many choices. Every one of them could be an act of resistance. Julian Köpke will speak on how to move against the grain. goatmire.com/talk/a-rebel... #elixirlang #goatmire

Just signed up for pushin.eu! pushin.eu/runlevel0

I love this framing, but in reality we treat developers of our internal platforms like users, and not customers, because most enterprise developers cannot behave as customers, and are forced to use whatever the platform engineering team gives them.

🥳🎉Today is the day🎉🥳 @hugobarauna.com, my brother and I are ready to release Elixir for Finance! We've poured all of our knowledge and know how into what we believe is one of the best programming+finance books out there 😍. 👉 financialelixir.dev #ElixirLang #Erlang

Acadia is out today! Bringing the benefits of Elm to SQLite and PostgreSQL: - Friendly error messages - Custom types for precise column data - Simple module system for easy reuse Check it out! acadia.engineering/blog/rethink...

v1.1 is planned for September, ahead of KanDDDinsky in October. New entries, more essays, and further updates to the theoretical framework. The series keeps going, and so will the book. www.organisationaldysfunctions.com #OpenSystemsTheory #SocioTechnical #OrgDesign

There's a new FP Stammtisch #Munich announced for July 30th: luma.com/2jcawymw Come join us if you are curious about, interested in or care about pragmatic #FunctionalProgramming! Everyone is welcome, regardless of experience level or background.

Just found this guide on #FullStack apps on Gleam lukwol.github.io/gleam-guide/, great for folks getting started with @gleam.run!

I have just finished the read and can only say that this is relevant to anyone working in Tech nowadays. Strongly recommended!

F# runs natively on .NET, and Fable compiles it to JavaScript, Python, Rust, and the BEAM. Five runtimes, one type-checked source, runs anywhere your stack needs it. BEAM is what Ericsson built to keep phone switches from ever going down. fable.io #fsharp #fablecompiler

Functional Domain Modeling with Gleam? Yes, please! Watch Eduardo's talk here: www.youtube.com/watch?v=15Sc... @runlevel0.me #gleamlang #gleamnews @codebeam.bsky.social

An excellent showcase of how great testing tools and good testing looks like in practice!

Why is there something instead of nothing?

Yes, this is what #TDD is all about, even if you don't use #ElixirLang! www.youtube.com/watch?v=5IJs...

There should be official posts soon. I had the brainwave and some spare effort to build this. The Erlang Ecosystem Registry. Register your company. Show how many we actually are. Keep up to date on major ecosystem initiatives. All free. marketing.erlef.org/news/registr... #elixirlang #erlang #gleam

they don’t want types, they don’t want safety, they want to endlessly *critique* type safety

there's something very satisfying about realizing you know two very excellent people who don't know each other yet, and getting to introduce them. Awesome Person 1, meet Awesome Person 2. the world is now a better place. repeat.

Some useful public speaking tips from Freud here.

After some date juggling, our Elixir & Erlang Munich - May 2026 Meetup is officially on! We'll have @j4nk.dev demonstrating how to integrate Rust into a Phoenix LiveView app using WebAssembly in the browser and Rustler in the backend. www.meetup.com/elixir-munic... #ElixirLang #Erlang #Rust

Announcing our next Functional Programming Stammtisch event! Whether you use FP at work, on side projects, or are simply curious, you’re welcome to join! 🗓️ Wednesday, Apr 29 - 18:00-22:00h 📍 Leo's Lounge Restaurant Bar More infos & RSVP here: luma.com/ezy53xth #FP #Munich #TechCommunity

Most 'transformation' fails because it tries to change behaviour without changing constraints. People aren’t resisting; the system is working exactly as designed.

I'm starting a monthly get together in Munich for people who care about functional programming and using it in practice. Whether you use FP at work, on side projects, or are simply curious, you’re welcome to join! Details and RSVP here: luma.com/o81km60y #FP #Munich #TechCommunity

Smart people in the right environment move incredibly fast. Then they see how slow most places really are. As @tastapod.com puts it: great teams ruin you for other jobs.

We have a consulting group, now open to work in a variety of languages, including Scala, Haskell, Rust, Elm, and of course Unison. More details here: www.unison-lang.org/blog/consult... Please boost to help get the word out. And we'd love to hear from you if you're interested in working with us!

Actively looking for my next role as a Senior Software Engineer Focus: iOS (Swift). Also backend (Java/Kotlin, TS, Swift). 10+ years shipping apps. Love building scalable and reliable systems 🇩🇪 German citizen (EU work auth) CV: github.com/akbashev/akb... Reposts appreciated 🙏 #Swift #iOS #Backend

I'm now on Nolto :D nolto.social/profile/runl...

You can vibe code your way to a working prototype. You cannot vibe code or one-shot your way to a competitive product that works at scale. The hard part isn't writing code; it's the architectural supervision.

"Software is no longer seen as an asset, as something to care for, to maybe even take pride in. It’s a throw-away product. Like a napkin. Just get one quick, wipe your mouth and throw it away. Like a novelty t-shirt." Software as Fast Fashion

The art and skills for delivering software in much more smaller incremental steps were lost with the global adoption of Pull Requests.

Does anyone here know which books one should read to get *really* good with #Postgres? #PostgreSQL #LazyWeb

I started a lu.ma calendar for SWE meetups in Munich: luma.com/devmuc Please share & subscribe if you're interested in meeting people in #meatspace Next up: @elixir-munich.org on Tuesday, 25th. Nov. #munich #meetup #swe #elixir

Focusing on the Rust Unwrap in the CloudFlare outage is really the scalability equivalent of "When a sage points to the moon, all the fool sees is the finger". At that scale, failures *will* happen. Programming error are unavoidable. What's interesting is why it took down the entire system.

No, hiring isn't hard for #OCaml. The Blub paradox is real. I have 30 resumes in my Inbox. The hard part is saying no. terrateam.io/blog/is-ocam...

Did you know that according to ISO 27001, 8.28 Secure coding, pair programming, refactoring, and test-driven development are considered to be secure coding practices? Next time someone ask, shh, just let it happen!
