Think of it like a Quickstart for working with claude code and Elixir projects, that leans on all the conventions we've been working on like tidewave & usage rules.
#ElixirLang

Totally feel you... I keep trying too, but Twitter pulls me back. I think the big issue is Bluesky hasn't hit the tipping point yet. If more key people like you made the jump _at the same time_, I think the rest would follow. Right now it's hard not to bounce back when things feel too quiet here.

Elixir / Ruby Lead Developer | Jobs at 9elements 9elements is a home for coders and designers, a place for the makers and shakers, a playground for the crazy ones. It could be yours as well.

You will find a great team, short decision-making paths and modern tech & tools. We believe in work that fits into life, with fair working hours, an open culture and room for personal development. We genuinely enjoy what we do, and work together to keep it that way.

We are looking for an #elixirlang / #rubylang lead developer in Bochum / the Ruhr area. If you love building great software instead of managing bullshit tickets, know how to work with clients and how to make sure your team grows, let's chat!

As AI redefines software development, this post by @ichimnetz.com stands out; tracing how automation shifts value from craft to concept, from 19th-century painting to today’s programming. Appreciate he draws thoughtful parallels without pretending to predict where it all leads.

#ElixirConf 2025 was absolutely wonderful. First one since 2017, and the community is still just as great, lovely, and open. Tons of inspiring talks and conversations, can’t wait to try Ash AI! See you at the next one, hopefully not in another 7 years.

Count me in - Would love to chat!

So excited for the upcoming @elixirconf.bsky.social in Krakow - Can’t wait for all the amazing talks and to meet more awesome folks in the #elixirlang community!

If you need your LLM to follow instructions better, try GPT-4.1. I’m building a chatbot with more complex behavior and struggled to get 4o to follow instructions properly. Switching to 4.1 fixed it, even without gimmicky styles to signal what's important.

Yes! I saw you released the lib you were talking about, great job!

So, I decided to visualize it and asked Cursor to quickly generate a page to illustrate the idea. It didn’t disappoint - and it was faster than I could have explained with my less-than-perfect drawing skills.

A digital interface displays a ‘Weekdays’ calendar with a colorful and playful design. The top section includes a row of buttons representing days of the week, each paired with an emoji (e.g., a moon for Monday, fire for Tuesday, water drop for Wednesday). Below, a number input with plus and minus buttons allows for selecting a numerical value, currently set to 15. The lower section presents a calendar-like grid with labeled weekdays and corresponding numbers. Some days are highlighted in different colors, such as Friday (yellow) and Saturday (pink). An arrow and emojis (a sprout and a rainbow) suggest a transformation or mapping concept. The overall aesthetic features soft purple tones with bold, rounded typography.

This morning, I talked with my daughter about weekdays - specifically, what day it will be after a given number of days. I explained that adding multiples of seven doesn’t change the weekday, only the remainder matters. Not the easiest concept for a four-year-old.

Package Version MCP Server - For AI Tools Help AI tools like Cursor to automatically use the correct package versions when adding dependencies to your projects. Supports Hex, RubyGems, and NPM packages.

Yesterday, I released a tiny MCP server that allows Cursor Editor to get up-to-date version information for external Hex dependencies. Someone suggested doing a version for #RubyOnRails, so I built a more generic version that supports Ruby Gems, Hex, PyPI, and NPM.

Hex MCP Server - Package Versions for AI Tools Help AI tools like Cursor to automatically use the correct package versions when adding them to your Elixir projects.

I am currently using Cursor to build a #elixirlang #phoenix application. It kept adding outdated package versions, so I decided to build an MCP server to solve this issue. If you are experiencing the same problem, give it a try:

Got my @elixirconfeu.bsky.social tickets, super excited to meet the #elixirlang folks in person!

Get well soon, Lucian!

#ElixirLang devs - what are you using for performance metrics? Telemetry + Prometheus + Grafana? StatsD + Datadog? Something else?

I am incredibly proud of the work of @molily.de and his team at @9elements.com, visualizing public health data on the WHO data hub. If you are into data visualization, this is certainly worth a look!

I thought it might be fun (and possibly helpful to others) to create a thread to document the things that I learned or used for the first time while doing AoC with Elixir. #adventofcode #elixirlang #myelixirstatus

Oh you are right, thank you! Should be fixed now.

Really happy to see my post about Phoenix LiveView session storage featured in the latest issue of the great @elixir-radar.com newsletter - This means a lot to me, thank you!

Support {...} interpolation in body by josevalim · Pull Request #3514 · phoenixframework/phoenix_live_view The first commit has the code changes.

Oh hell yes, I actually can't wait. This was my main gripe with #ElixirLang templates.

“You suddenly have superpowers. You almost don’t notice it. Being freed from all the mundane concerns of typical full-stack development lets you focus on just shipping features.”

Love this part; absolutely on point.
