pi_ex Elixir client for the Pi coding agent RPC protocol.

I just published hex.pm/packages/pi_ex, an #ElixirLang library for interacting with pi.dev agents (the thing that powers #OpenClaw).

I included some example apps to demonstrate how it can be used. Try it out!

No more excuses to not go one level deeper My favourite thing about LLMs

Another one of my favourite things about AI: the barrier to diving in and understanding problems one level deeper, is lower than ever.

Hong Kong’s Famous Bamboo Scaffolding Hangs On (for Now)

And also this article from nytimes: www.nytimes.com/2025/05/24/w...

Why Hong Kong uses bamboo scaffolding: visual explainer An ancient practice, suitable only for people with nerves of steel, remains alive and well in a modern city full of skyscrapers.

The recent news reminded me of this amazing interactive article from 2022: multimedia.scmp.com/infographics...

I tried Kagi for a year, went back to Google for a few months to make sure I wasn't hallucinating the improvements, and now I'm back. Kagi is great!

Apparently ThePrimeagen will be writing an app in Elixir (live on Twitch), then inviting @josevalim.bsky.social to the broadcast to rewrite it together. That seems like a pretty dope approach for learning a language. And sharing the gospel of #elixir of course.

Comment by Workaccount2, 9 hours ago: They poison their own context. Maybe you can call it context rot, where as context grows and especially if it grows with lots of distractions and dead ends, the output quality falls off rapidly. Even with good context the rot will start to become apparent around 100k tokens (with Gemini 2.5). They really need to figure out a way to delete or "forget" prior context, so the user or even the model can go back and prune poisonous tokens. Right now I work around it by regularly making summaries of instances, and then spinning up a new instance with fresh context and feed in the summary of the previous instance.

Workaccount2 on Hacker News just coined the term "context rot" to describe the thing where the quality of an LLM conversation drops as the context fills up with accumulated distractions and dead ends news.ycombinator.com/item?id=4430...

Your Phoenix application, directly on your Tailnet Your Phoenix application, directly on your Tailnet - 2025_06_08_libtailscale_elixir.md

Philip Munksgaard created an Elixir wrapper for libtailscale, so it's now possible to run a Phoenix application that is automatically connected to your tailnet.

Amazing work.

I use the "Chat with Copilot" button (at the top right corner of any Github repo) pretty often, to quickly understand how a codebase works. Where the entrypoints are, how certain functions are used, what core libraries it depends on etc.

TIL: Bash caches the paths of commands .. to speed things up. Obviously.

This TIL gave me the motivation to create a TIL blog finally

Introducing Tidewave: tidewave.ai

While working on our web apps, we run code, query the database, read logs, search docs… but our AI tools are limited to reading code.

Tidewave closes this gap by introducing Runtime Intelligence, for Phoenix and Rails. More coming soon, check out the website!

+1. This is the painful side of the dual edged sword of Phoenix's usage of codegen rather than an abstraction layer. If the new things are part of the generated code, you are expected to maintain them, so you gotta apply the patches manually.

I hope I'm wrong. Does anyone know a better approach?

Is it open source? 😇

I made a font A quick look into the process of creating a font.

I'm excited to share that I created a font!

It is monospaced, and designed to be used in code editors and terminals. Fellow programmers, do try it out and give me some feedback!
