Just landed an ultra-rare +0/-0 PR. Yes, we merged this, yes it did something we cared about. Can you guess what it was?

I had a great time speaking at the first iteration of @exmexconf.bsky.social! The slides for my talk titled "Automating My Office" are up on my GitHub: github.com/axelson/talks #ExMexConf #elixirlang

Write code to make being human easier. Rip code out if it makes being human harder. Write code to make caring for each other easier. Rip it out if it makes caring for each other harder. Empathy driven development has literally never failed me. It’s done me better than everything else combined

Who do you know who wants to come work full time on #ElixirLang OSS tooling? (Boosts appreciated!) jump.ai/careers?ashb... #ElixirJobs

🚨 New Blog Post 🚨 I just finished this monster of a blog post! How to listen to database changes through the Postgres WAL! This is all @filipecabaco.com's fault who nerd-sniped me into low-level Postgres details! Click here to suffer too: peterullrich.com/listen-to-da... #ElixirLang #Postgres

Many such cases. Life gets so much better when you rip that Bandaid off.

#ElixirLang folks, I would *really* like my org's test suite to run with zero log messages printed unless there's a real error. How do you get to the Promised Land here?! Not all messages are deterministic, so if I fail CI due to logging, people get mad when it wasn't introduced by their change.

Hit off-by-1 errors in timing related tests when upgrading to Elixir 1.19. Turns out DateTime.diff changed subtly, it used to drop microseconds (everything rounded to seconds), now keeps them. Our tests relied on old behavior without realizing it. Hopefully saves ppl some debug time! 😅 #ElixirLang

How your email finds me

Hey so I’ve been looking for my next role and striking out. If you know anyone looking for an Elixir dev with experience managing and advocating for teams, I’m your guy!

Help, what's this new HexDocs UI?! :D

It’s easy to hate on this, but from the product side, it’s hard to prioritize letting somebody create a bunch of data in your app that they’ll never be able to retrieve again.

Send me a screenshot of your donation and I’ll match it. (Let’s cap it at $2,000 so my wife doesn’t murder me. 😆)

Realized this myself the other day and finally set up a recurring donation to harvesters.org. Do the same for your local food bank!

“Did you hear about this hot new startup? They’re on track to becoming a Garfield in the next couple years.”

Rare political post: Lots and lots and lots of people near you are about to be going hungry. Food banks need your donations like never before. www.politico.com/news/2025/10...

How do people handle required fields in LiveView? My instinct is to mark it `required` in the DOM and let the browser's native UI say "hey, you forgot this" when the person tries to submit the form. But going that route, there's no way to say "actually you forgot these 3 fields." #ElixirLang

Meet Elixir Language Tour – a tool created to make Elixir learning easier 🪄 Written in pure Elixir, running fully in the browser – all thanks to Popcorn 🍿 Check it out – link below!

I saw some TypeScript written with one function per file, and one directory per function+test file pair. WHO HURT YOU?! assets/ --> functions/ ----> build-url/ ------> build-url.ts ------> build-url.test.ts ----> download-file/ ------> download-file.ts ------> download-file.test.ts

Elixir 1.19 released! 🎉 This one had a lengthier rc period. It brings type system improvements and compile time improvements in large projects among other things 🚀 elixir-lang.org/blog/2025/10...

Sweet #Ecto datetime helpers? Yes, please! 😄 - ago, from_now, date_add, datetime_add 👨‍🍳🤌 #ElixirLang

For myself to more easily find again later. (GitHub Markdown "alerts") docs.github.com/en/get-start...

🚨 New Blog Post 🚨 EXTRA EXTRA! Hot off the press! The power of binary pattern matching revealed! The in-depth investigation you don't wanna miss! Get your copy now! #ElixirLang peterullrich.com/binary-patte...

Tell my wife and kids I love them.

Oban? More like Whoaban. #ElixirLang

This guy… 😆

This PSA has a corollary PSA: Your users aren't reporting bugs. Nobody (99.9%+) reports bugs. Listen when someone reports a bug, because that person is probably speaking for 1000 others.

PSA! It's so easy to forget to handle websocket reconnects in LV, but if you're deploying regularly, your users are likely seeing A LOT of bugs coming from this. Go to one of your pages, click around a bit, then run `liveSocket.socket.triggerChanError()`, and see what happens. #ElixirLang

🚨 This is not a drill! 🚨 Another Rush tour is happening. youtu.be/koiX_Wspatw

Any hints on how to implement resource sharing in ExUnit tests? For phoenix_test_playwright, I want shared browser instances. Browser pool, each test module has to wait for available browser in `setup_all`. github.com/ftes/phoenix... Have you seen/implemented something similar before? #elixirlang

New MDEx (Markdown for Elixir) version is 🔥 👇

The best part of using GCP is how the log explorer locks up the whole browser for 15 seconds while it loads the skeleton of the UI, prior to querying any data at all. A nice mindful moment built into various points of each day. 😌

My favorite category of AI code generation: when the AI can't get a test to work, so it writes something in the test file that absolutely doesn't touch the function "under test" at all.

Don’t let the age of this article from @germsvel.com scare you off, vertically slicing features is still a great idea: www.germanvelasco.com/blog/break-a... #AgileDevelopment

Excited to be speaking at #CodeMash for the 3rd time in January. I haven't checked sessions for previous years, but I'm reasonably confident that I'm giving the first ever talk on unionization in the software industry that CodeMash has ever had. I have no idea what kind of reception awaits me. 😅

I woke up and decided to write something to promote #ElixirLang more, since it brought us so much. "Sometimes the best tool for tomorrow’s problem is the one that’s been quietly excellent all along." petar.dev/posts/elixir...

Hey Elixir family, process spawners, fault-tolerant friends! 😉 My ElixirConf talk just dropped! See how Hologram is pushing the boundaries of what's possible with Elixir! Check it out: www.youtube.com/watch?v=TVs2... #Hologram #Elixir #ElixirLang #BEAM #WebDev #ElixirConf

I like this! I’m especially stealing Result.wrap_not_nil/2.

Boy, that LiveView 1.1 update is a doozy, huh? #ElixirLang

Got a message that my 12 month free tier account with AWS SES is expiring. I checked my usage and I said about 300 messages a month. At $0.10/1000 emails, Amazon will literally be losing money on the transaction fees if they actually bill each month. I’ll be interested to see if they do.

This is a font joke.

If you'll just merge my PR now, I solemnly vow that the very next thing I work on will be addressing the issues you brought up. (That code is never getting written. 😅)

If you'd like the amended version of the Credo check that would have caught this: github.com/rrrene/credo...

Interesting question came up on Reddit. Many popular #ElixirLang packages see drop in downloads number decrease by around half starting this week. Phoenix, Ecto, Jason, Req, Mimic, Mox - these are some I looked up and it checks out.

Pop quiz time: Given a published post with an associated user, what gets printed here? if user_id = post.user_id && post.published? do IO.inspect(user_id) end Hint: It ain't what I thought. 😬 #ElixirLang

Hypothetically speaking... if I were to build an Elixir-focused error and performance tracking tool, what would you like to see in it? 🧐 #ElixirLang

Let’s gooooo! Create a real application with the Ash framework! #elixirlang youtu.be/zM_-Y4diVFw?...

@posthog.com The new web site feels like an April Fools joke... as part of a team paying $$$$/month, I can't figure out how to get into the dashboard to actually use the app. 😬

Me at 4:58 pm: Okay, I've put out all the fires. Now to get to the work I actually needed to do today. 👀
