Everyone is talking about #omarchy , but if you are not ready to switch to Arch or too comfortable with GNOME, you can try my opinionated tiling setup for GNOME. It's distro-agnostic, so it works any distro: github.com/lcmen/omagnome Enjoy!

What's the best way to learn about some new concept? Building a project using it! Recently, I've been interested in MCP servers, so I built one with Ruby (and `fast-mcp` gem). It allows you to query HackerNews (as what else can you do on Friday 😅). Code: github.com/lcmen/hn-mcp/

Another idea inspired by the Ash Framework book: my journey into the pin operator and macros in #Elixir. Check it out: www.mendelowski.com/blog/2025/03... I'm not an Elixir expert, so I welcome feedback from more experienced Elixir folks. Hope you enjoy it!

Hey @chastell.net, @tomash.eu mentioned that you were able to configure AI assistant in Vim (NeoVim?). Can you share your setup? Were you able to replicate VSCode / Cursor experience in applying changes from chat window to source files (Composer like behavior)?

Recently, I started reading the "Ash Framework" book. While building the example app, I spotted an area for improvement - leading to my first-ever contribution to the 🧪 Elixir ecosystem! My changes to @ash-hq.org and `ash_postgres` are ready for release! 🚀 #MyElixirStatus

If one of your 2025 resolutions is to explore modern front-end solutions for #rails, I’ve got you covered. Check out my blog post and repo comparing #Hotwire, #htmx , #unpolyjs and #inertiajs. github.com/lcmen/hotwir... www.mendelowski.com/blog/2024/11...

I know that no one asked for it, but I've added #inertiajs to the mix (with React without JSX transpilation!). Compare it with #hotwire, #htmx, and #unpoly. The same principle as before: single controller, no build, importmap, and propshaft.

#TIL that #postgresql allows you to create custom aggregate functions www.cybertec-postgresql.com/en/writing-y... Nice!

Writing your own aggregation functions
Database engines usually provide basic aggregate functions. This shows how to create your own code to calculate on the server side.

@solnic.dev quick questions about your justcrosspost.app! 1. Which AI tool were you using for HTML templates? Was it consistent in design across different elements? 2 Are you using any unique Elixir/Phoenix features that would be tough to achieve in Ruby/Rails? Thanks!

Some people asked me about my experience with #hotwire, #htmx and #unpoly while building the app. I summarized my insights in a follow-up blog post: www.mendelowski.com/blog/2024/11...

Hey everyone! It's my first post here. Just want to share that recently, I've built a simple TODO app with Rails to compare #hotwire #htmx and #unpoly. It follows progressive enhancement spirit (the same controller is used for all the variants). You can check it here: github.com/lcmen/hotwir...
