Once more, with feeling: My #ElixirConf 2025 talk is live! www.youtube.com/watch?v=8mum...

Checks out. Some related research - "employees worked at a faster pace, took on a broader scope of tasks, and extended work into more hours of the day, often without being asked to do so" "...leading to workload creep, cognitive fatigue, burnout, and weakened decision-making" hbr.org/2026/02/ai-d...

"How AI Impacts Skill Formation" from Anthropic researchers: > We find that AI use impairs conceptual understanding, code reading, and debugging abilities, without delivering significant efficiency gains on average. (Continued) arxiv.org/pdf/2601.20245

Quokka is always the first dependency I add to every new project. Such a great tool! And no more “oh my editor formatted it differently, sorry” or “damn I forgot to sort my aliases and now my CI failed”. Brilliant

There’s a new release of Quokka, and it’s a big one. Lots of both new and improved rewrites to automatically make your codebase nicer. 💜 github.com/emkguts/quok...

Anybody have contacts at PagerDuty? I’d love to ask them about their usage of #ElixirLang. They had a blog post in 2020 about it, but I can’t find anything they’ve written since then.

Loved this talk from Mitch Hanberg about the origin story and architecture of the new #ElixirLang Expert LSP. youtu.be/2vIw2fb9DxA

This person made a production management tool for his spouse's bakery in #ElixirLang + Ash + LiveView. It's super valuable to have an codebase like this be open source for people trying to get into that tech stack. 💜 github.com/puemos/craft...

For even more fun, you can capture the struct module 😁 def add_one_hour(%date_or_time{} = value) when date_or_time in [DateTime, NaiveDateTime, Time] do ... end

@june.bash.pizza I dig the song. A little Vangelis, a little hip hop, a little Mass Effect soundtrack. 🔥

Hey Elixir friends! :) Hologram's journey just took a big leap forward: @curiosum.bsky.social is coming on board as the Main Sponsor, and I'm joining their team to work on Hologram full-time! Read what this means for Hologram: hologram.page/blog/hologra... #Hologram #Elixir #ElixirLang #BEAM

Cursed indeed 😂 llm_if value, “divisible by 2?” do IO.puts(“even”) end

An official VSCode extension for Expert LS has been released. You can be a 30th person to download it. marketplace.visualstudio.com/items?itemNa... #elixir

Hold the phone. Am I the only one who didn't know (or likely forgot) that you can press opt+shift when pressing the volume keys on a Mac to switch to 1/4 increments? Life. Changed.

I like this setting for VS Code from Ben Frain. JUST show the vertical line for the current indentation, not all of them ``` "workbench.colorCustomizations": { "editorIndentGuide.background1": "#00000001", "editorIndentGuide.activeBackground1": "#ff9900" } ``` benfrain.com/vs-code-high...

TIL Oban's unique job period uses fixed time windows, not sliding windows. A job with unique: [period: {7, :days}] can still allow duplicates 2 days apart if they fall into different buckets. If you need sliding windows, use a custom query. ftes.de/articles/202... #elixirlang #oban

I'm on a mission to find every Enum.each/2 in the tooling I use and replace it with Task.async_stream/2 😁 github.com/nccgroup/sob... #ElixirLang

For those of you wanting to start a new project in the new year but afraid you're gonna suck, heed the words of the ancient texts:

Credo 1.7.15 is out now, with massive perf improvements for large #ElixirLang codebases.

statmodeling.stat.columbia.edu/2025/12/24/s... Some new insights here and there on why it feels offensive when somebody copypastes a ChatGPT reply verbatim.

100 concurrent PDF renders completing in ~22ms total, how cool is that? #ElixirLang #PDF #typst

The type system progress stuff is exciting!

Very excited to dig into this, @jkwa.bsky.social! #ElixirLang

Somebody at work referred to me as “the frontend guy.” We’re cooked. 👀😅

Speaking publicly about Elixir stuff (conference talks + podcasts) has gotten me every job I've had since 2020. (And that first one was a 50% pay bump.) I interview pretty poorly, but having been seen being smart in public got me the foot in the door I needed to prove I could do the work.

Another talk where the speaker is really into using web components (and Lit) whenever LiveView falls short: www.youtube.com/watch?v=mEnN...

We're launching our new Elixir book! 🎉 Programming Nerves: from web developer to hardware maker. If you've ever been curious about hardware but felt intimidated, this is for you. Beta available now (38% off), or download free chapters to get started. #ElixirLang

Couldn't fit optics in my book, but I can build them into Funx. Here's why lawful lenses matter (even in Elixir): www.joekoski.com/blog/2025/12... #elixirlang

BRB, gotta go write a migration for the work DB.

Loved this talk.

Async tests are great… until shared global state ruins your day. In this new article, @marpo60.bsky.social breaks down how using ProcessTree gave each test its own isolated environment — solving flakiness and making async tests safe again. 👉 www.mimiquate.com/blog/how-pro... #Elixirlang

My #1 takeaway from the 2025 Elixir survey: Quokka is up-and-coming, but not big enough (3.8%). If you're using Credo but not Quokka, you're missing out. elixir-hub.com/surveys/2025

Published a little LiveDashboard page for managing some data migrations. hex.pm/packages/dat... #ElixirLang

Productive day today.

to commemorate alan dye moving from apple to meta, here's one of his best quotes

I just figured out how to execute LiveView.JS commands from a JavaScript hook! This is useful for manipulating the UI directly from your LiveView. For example, here I'm closing a modal after a `handle_event/3` callback succeeded. #ElixirLang

Got a few PRs in flight for Credo which cumulatively dropped the runtime from ~33 seconds down to ~9 on our 3500 file #ElixirLang codebase at work. 😁

News includes OTP 28.2 release, significant update to the "whois" library, Tidewave adds Figma support, KQL parser library, EEF vulnerability data on OSV-dev, and more! Plus: designing for failure vs handling errors. #ElixirLang www.youtube.com/watch?v=O-1z...

Software Mansion released v0.5.0 LiveDebugger. Looks like high quality release! - Calculate assigns size - Trace diffs sent to browser - Add dead LiveViews section - Add resources page - Add history of assigns - Async loading support - Add streams section #ElixirLang

Wow!

I may be the only one parsing WHOIS records in #ElixirLang, but the latest release of the library I maintain for this has big improvements for compatibility with a wider variety of domains. github.com/utkarshkukre...

Yoooooooo 🙌
