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 😅).

I'm still switching between NeoVim and Zed but here are my settings and keymaps:

No worries at all. Hope you feel better soon. Take it easy.

How is it going so far? Also, is the pro plan generous enough with its prompt limit? Do you know if it switches to simpler models like Cursor after reaching the limit?

Good spot👌. Fixed!

Understanding the Pin Operator and Macros in Elixir - Lucas Mendelowski Understanding the Pin Operator and Macros in Elixir by building custom DSL

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!

That sounds awesome. I'm looking forward to it!

How is Zed so far? I personally moved to Cursor but still miss good old days with Neovim and tmux...

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)?

Mine is only 278 with style of posting described as "Reply Guy" 😄. Social status: "Highly Engaging Explorer" with exceptionally high engagement, averaging 2.6 engagements per post across their follower base of 48.

Thanks for sharing the website, it's cool to see such summary!

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! 🚀

Thank you so much, @inazarova.bsky.social !
That’s so kind of you.

What editor is that? How did you enable Prism for syntax checks? Thanks!

GitHub - lcmen/hotwire-htmx-unpoly: Simple TODO application built with Rails to compare Hotwire, HTMX and Unpoly Simple TODO application built with Rails to compare Hotwire, HTMX and Unpoly - lcmen/hotwire-htmx-unpoly

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.

That would be better turnaround for Bears than another no 1 QB from the draft.

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.

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.

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

Nice!

I'm still using alacritty with tmux. Muscle memory dies hard.

Thanks for explanation and happy birthday!

What do you mean by M:N threads?

Thank you for taking your time to answer my questions. I appreciate it 🙏. I've also signed up for beta and I'm looking forward to play with the app 🎮.

Btw. I saw your question on LIn about the ElixirConf talk topic. I honestly would love to hear your experience in transitioning from Ruby to Elixir.

@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...

Oh, nice! I didn't know you can record, edit and replay bisects. Thank you for sharing!

Thank you!

Hey, hey 👋
