You are really not doing Emacs justice by using it on the Mac. Emacs is enjoyed best on Linux.

Look at me optimizing my workshop instead of building the thing. The whole dev space is addicted to productivity porn.

"Never ask a barber if you need a haircut." Never follow advice from someone at Anthropic or OpenAI how much tokens you should burn.

Would love to give this a try to see if I can get a nice view transition going. Anyone tried it already? #elixirlang github.com/phoenixframe...

Looking for #elixirlang developers that want to work with me at Workera.ai. Remote in either the Netherlands, UK or Ireland. Send me a message if you want to know more or apply. job-boards.greenhouse.io/workera/jobs...

The most powerful form of AI collaboration is not AI generating code but using AI for understanding code.

We have an open position for an #elixirlang developer in the UK, Ireland or the Netherlands. You can find the post here, or reach out to me directly. job-boards.greenhouse.io/workera/jobs...

It's still a shell of a library, but personally I'm really excited about it. BEAM nodes are easy to deploy near users, getting the data there as well has always been the hard part. Hopefully this solves that. For now, it's just me having fun with NIFs. #elixirlang github.com/bytebottom/t...

I'm learning so much about how the beam works by implementing a library with Rustler. Very interesting stuff. #elixirlang.

@drewr.dev love the things you are doing with ecto_libsql. I was thinking to leverage the new turso library so I get the vector and search support that it has. Were you planning to support the new Turso library at some point? What's your thinking on that?

Big upgrade to my Claude Code. Guess which movie this is?

Design is the work now. Cognitive debt is the newest drag on productivity. petar.dev/posts/cognit...

3rd rewrite of a new agentic system in 48 hours. Frustrating? Yeah, a little. But I'm learning so much. It's a relentless loop: hours on the design, execute fast, hit reality, learn, restart. Each pass I'm making fewer mistakes and building real intuition for how the system I'm building works best.

Maybe if I reach a 1.000 followers, my kids will think I'm a cool dad.

If Codex fails on #elixirlang with "failed to open a TCP socket in Mix.Sync.PubSub.subscribe/1, reason: :eperm" try this setting in your ~/.codex/config.toml: [sandbox_workspace_write] network_access = true

It's the small things, but things like this make agentic coding in #elixirlang much better.

This is a very interesting project that pairs perfectly with #elixirlang LiveView, where data locality is so important. Put servers around the world (easy), have data close to the user (hard). github.com/ocean/ecto_l...

Anybody by any change have a Lobste.rs invitation for me? There are some good discussions happening there and would love to participate.

My thinking on Finde has evolved and I couldn’t be more excited. The scope is bigger and sharper: a second brain that improves while you sleep, with you driving every decision. While it with blogging, a blog is now just an output of you sharing one of your notebooks. beta.finde.app

I like to work on the server, but copy-paste was not working in my Ghostty/Tmux and OpenCode setup. After some debugging, I got it to work: petar.dev/notes/copypa...

Made my #neovim theme available. Also lots of extra to have harmony with ghostty, tmux and opencode :) github.com/wunki/gondol...

Brain fart, record all key strokes and commands in Neovim. Give that to an LLM to analyze. Let it make suggestions to improve your flow.

Happy 2026! I reworked my landing page for Finde. What do you think? Is it clear what I'm trying to build here? Like the design? Would you use it? beta.finde.app

Working hard to release the first version of Finde before the end of the year. I think AI is here to stay and is very useful, but we can't let the internet drown in slop. Finde is trying to solve that. beta.finde.app

I tend to work with Neovim and OpenCode side-by-side, but did not like it that I had to visit Neovim for the buffer to be updated with the changes. Easy fix, now the buffer always represents the latest changes, even if Neovim is not active: github.com/wunki/dot-nv...

You can just do things now... So I wrote my own Neovim theme. Pretty happy with the results:

TIL: Rap stands for Rhythm and Poetry.

I published my first Hex package. Making it easy to work with Git worktrees in your #elixirlang and Phoenix project. Still pretty atuned to my my project configuration, but it may be useful for others. hexdocs.pm/tak/

Easily work on multiple features with #elixirlang and Phoenix with the help of Git worktrees. No more broken LSPs, missing migrations or conflicting ports. www.youtube.com/watch?v=t6l7...

Pretty happy where I landed with the landing page (pun intended). Blog engine where you connect your Claude or ChatGPT. It reads your blog, looks at your analytics, and suggestions appear live as you chat. Everything goes through a review queue, you never lose your voice. #elixirlang ex.finde.app

I'm going to plan a holiday where I read Manning books during the day and watch Lord of the Rings at night. That's it.

The "March of Nines" is such a great way to talk about software development: petar.dev/notes/the-ma...

Svelte good a huge DX boost with remote functions. And grateful for @joyofcode.xyz to create a banger video explaining them, walking through the tutorial has been lots of fun. www.youtube.com/watch?v=Ldnm...
