I’m way too giddy for this

new blog post! why do LLMs freak out over the seahorse emoji? i put llama-3.3-70b through its paces with the logit lens to find out, and explain what the logit lens (everyone's favorite underrated interpretability tool) is in the process. link in reply!

Recently discovered @pagedout.bsky.social, a free experimental (one article == one page) technical magazine about programming tricks, hacking, security hacking, retro computers, modern computers, electronics, demoscene, and other similar topics. Ya'll might love it too.

IBM Model M from 1984, always wanted to try one of these

TL;DR - Brooklyn is dope and the RC community is awe-inspiring.

Day 3 @ Recurse Center and I’m already trying to learn C, Zig, CTF/NetSec, soldering, and Elixir. 24hrs a day ain’t enough.

Anyone in the #ElixirLang sphere doing cool things with Local First architecture? Something like @electric-sql.com, or making an Elixir version of Linear? I’d like to build a SQLite-backed web app with LiveView, please share any/all resources for getting started with Local First Elixir!

Wanna build a slightly janky, self-hosted val.town alternative for #ElixirLang? I got you.

@zachdaniel.dev great episode! Q regarding Spark: is it accurate to say it’s an alternative to Ecto embedded_schema? I’m writing a somewhat complex .json file parser for journal entries and deciding between a struct, embedded_schema, or Spark.

Has anyone read/worked through the Northwind Elixir Traders book? Came out in May so there's not a lot of reviews. #ElixirLang #Ecto #SQLite

Major kudos to any company that makes their docs LLM native. That little dropdown gives you a crisp markdown copy right into your clipboard. My shortcut has been prepending r.jina.ai/ to URLs but first party support is blissful. Shoutout to sequinstream.com devs 🫶

@zachdaniel.dev Looks like I'm the first to request an indexing of Ash Evals on DeepWiki, plan on diving in soon and curious how it fared.

Finally got around to playing with Tidewave MCP & Zed Agents to build a liveview app, shared my first impressions below. How in the world do you guys keep your agents from making a tailwind mess?

I took the 4 Anti-Pattern pages on hexdocs.pm (code, design, process, meta-programming) and smashed them into 1 markdown file so I can feed it to Claude for an #ElixirLang code review. 20k tokens, feel free to download a copy. Yes I know credo/styler exist.

I’ve bought nearly every #ElixirLang book released in ‘24/‘25 and would love to give my zed agent access to this rich knowledge base. Any ideas? RAG MCP? PDF MCP?

New month, new post. TL;DR - I started a business, got into the Recurse Center, and had a lot of time to connect with friends & family. This ones more of a look into my lifestyle than anything technical.

Love it when #ElixirLang/#Erlang is on the front page of HN. I'm always surprised by how much praise BEAMlangs get in the comments; being HN I always expect some haters but there's genuinely few.

When meeting new people or introducing myself, I sometimes mention that days after I was born, the Romanian Revolution began and separated me from my family for the next 3 years. This video is a wild trip through a time I can’t remember. P.S - no gruesome footage is actually shown

SSH experiences are underutilized. I know #Erlang ships with an SSH server (thanks to last month’s RCE vuln), wonder what sort of shenanigans you can make with SSH + #ElixirLang 🤓 Hackmud Clone?

I’M ATTENDING THE RECURSE CENTER IN SEPTEMBER. AAAHHHHHHH!! (just found out a min ago) #ElixirLang all day every day

Just picked up a virtual ticket for $99, can’t wait to e-meet you all! #ElixirLang #ElixirConfUS #myelixirstatus

I quit my job *just before* the November election, now 6 months later, I'm trying to answer some tough questions about my past & present choices. #ElixirLang

If any #ElixirLang devs have gone over the top with Phoenix Liveview presence magic, or know a site that did, drop a link! I want to see the most creative uses of pub/sub & presence tricks. Something like the @lawik.bsky.social underjord.io "Magic Enabled" toggle.

A little demo doing this in #ElixirLang / iex

🧵 Here's a chart showing monthly costs that @justcrosspost.app generates with info about each service and some screenshots 🖼️ #buildinpublic #crossposting #crosspostingapp #costs #solopreneur 👇🏻

3 months down, 9 to go. A recap of how & where it's going. TL;DR - I'm coming for you @recursecenter.bsky.social 😈 flaviuspopan.com/the-elixir-y...

Got FOMO after learning about Clojure's Interactive Development, so I found a decent solution for #ElixirLang flaviuspopan.com/repl-driven-...

One final blog post to conclude a 5 hour writing marathon 😌 flaviuspopan.com/the-elixir-y...

How I'm keeping my syllabus on track using a $12 app and lots of emojis. flaviuspopan.com/sabbatical-t...

I found a way to generate individually tailored #Exercism challenges, complete with working tests, a quirky backstory, and hints using a coding agent (Cline). Makes learning #ElixirLang a breeze while also reinforcing areas I need more time in. flaviuspopan.com/the-30-cent-...

@zachdaniel.dev would you recommend learning Ash before or after Phoenix & Liveview? Trying to slot it in my syllabus, will finish core elixir focus next month. flaviuspopan.com/elixir-year-...

I was surprised to find out that #elixirlang only added official JSON support in the latest release (1.18). Here's what I learned about how we got here. flaviuspopan.com/elixir-json-...

One month down, 11 to go. Here's where I'm at in my year-long #elixirlang technical sabbatical (hint: not far) flaviuspopan.com/elixir-month...

2 hours of @josevalim.bsky.social talking about Elixir? Yes please. www.youtube.com/watch?v=-mFJ...

I started using Exercism this week to learn #ElixirLang and holy smokes...HOW IS THIS FREE!?!?. I'm using their CLI lib with my own tooling so I can also run `mix test` locally. I'm in love. exercism.org/tracks/elixi...

For anyone else that's #ElixirLang curious, here's a very short guide for installing Erlang & Elixir on Mac OS via `asdf` to get the latest versions (Erlang 27.2 & Elixir 1.18.1) flaviuspopan.com/installing-e...

Really dope presentation about how well #ElixirLang fits with #LLMs, I'm seeing a ton of new projects popping up like Jido github.com/agentjido/jido that make use of all the goodies built into the lang ^_^ www.youtube.com/watch?v=TfZI...

I'm devoting 2025 to an #ElixirLang technical sabbatical. If you're an elixir/erlang expert or have technical sabbatical experience, please share your thoughts on how I can set myself up for success! 📚 flaviuspopan.com/elixir-year-...

Q for #ElixirLang gurus: would you advise elixir beginners still pickup Programming Elixir ≥ 1.6 (2018) or just stick with Elixir in Action (2024)?

Decided to give bearblog.dev a shot at hosting flaviuspopan.com after getting annoyed managing a WP site and feeling overwhelmed by Substack's options. Simplicity wins.

Spent the last two hours reskinning EVERYTHING to use Catppuccin Mocha. Compiler errors aren't as scary when they're printed in pastel. catppuccin.com Pro-Tip: Add the Dark Reader theme and you're 70% of the way there.
