Damn! StackOverflow is dead dead.

Someone good at finance please help me balance my monthly budget Ramen: $30 Rent: $2000 Claude API: $8730

How bad of an idea is it to buy a 24-core, 64GB RAM, 800GB NVMe rack server and put it in a local data center to replace my various shared-CPU cloud servers that cost 1/6 of the rack server per month?

The upgrade to 1.19 continues and we discover a long-time convenience being snatched away in favour of more explicit syntax as Elixir adopts gradual set-theoretic types. zarar.dev/struct-updat... #elixir #elixirlang #typesystems

After going through the very painful - but very interesting - process of setting up a self-hosted version of TimescaleDB, all I can say is: Be grateful for having managed database services ❤️ However, now I have another blog post to write! So, Yey :D

Happy new year fellow BEAMers! 🎉

The first music streaming app that lets me click a big checkbox saying “NO FUCKING BALLADS” on my high-power rock running radio will win my everlasting loyalty. I’m sick and tired having to skip every 2nd song during a high-intensity workout because it’s a fucking ballad

Great article about building double-entry bookkeeping in #ElixirLang by @zarar.dev 🙏 zarar.dev/building-a-d...

Portugal is so freakin beautiful caralho ❤️

What day is it?

@gworkman.bsky.social I thought you’d appreciate this bad boy. Look at that refresh rate! Mind blowing.

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

I'm using Typst now to generate PNG to be used as og images thanks to @peterullrich.com 's ogi library github.com/PJUllrich/ogi

Arrived safely in Portugal for the holidays. First task: fix the pellet heater (I’m not too happy we have one but it came with the house). After 2h of “debugging” it turned out the water pump was stuck and needed a little push. Now, it’s heating nicely. I love fixing physical things!

Uuuh, this is brutal. Bluesky went from 2.5m daily users to 1.5m this year. That’s the opposite of what a new social media platform should look like :(

If your product is customer-facing, all your most common use-cases should be self-service like this. If not, you’re burning money for nothing.

For as long as I can remember, I thought these were equivalent: 1) if foo, do: bar, else: baz 2) foo && bar || baz Until the day bar was nil. #ElixirLang

My trick to reduce spam emails in my inbox: 1. Buy a .email domain on Namecheap for $3/yr 2. Buy Namecheap’s Starter Email package for $12/yr 3. Use the new domain for all non-essential sign-ups 4. Ignore the mailbox for anything but confirmation and sign-in links 5. Enjoy the peace

Don't get me wrong, building web apps is immensely fun (especially if you are using LiveView). But building a physical circuit and interacting with it just hits differently. I've been having a blast putting together the Programming Nerves projects 😁. #MyElixirStatus #ElixirLang

Finally I was able to finish blog post pragdevnotes.com/elixir-nrf24... about my gitlab.com/boskoivanise... library. Next on the agenda is a post how it is used on #raspberrypi with #nerves and #arduino station. #elixirlang #nerves #MyElixirStatus

Welcome to Paris 😄

Gotta love Dutch internet. This one goes out to my friends in Berlin 😬

An enjoyable look at how LLMs work under the hood from @samwho.dev. The whole chain of tokenizers (text chunks), embeddings (vectorized text chunks), transformers (the "T" in ChatGPT), caching (reused chunks), and all the math that goes into returning a response. ngrok.com/blog/prompt-...

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.

At all my job interviews in the last 4 years, people knew my name already from my blog and conference talks. Sharing your work publicly is a HUGE advantage for your career and professional development.

Can’t wait to get my hands on the latest Alex-Hugo collaboration! They never disappoint!

🚀 Today is the day 🚀 @hugobarauna.com and I are pleased to announce that Programming Nerves is officially in Beta 🥳 Check it out at programmingnerves.dev and see all the cool projects that you will learn how to build and program with Elixir! #MyElixirStatus #ElixirLang

Thank you to the wonderful @akoutmos.bsky.social for creating this very useful library!

Getting ready to beta release "Practical Flutter & Phoenix" in a couple of hours. Thanks to all early purchasers 🙏 😀. This early version has elixir and phoenix crash course. I tried to stay focussed and only keep relevant topics. excited, but a bit nervous 😅

Wednesday is the day!! @hugobarauna.com and I are almost ready to release the Beta for Programming Nerves 🥳. Stay tuned for updates 😉. #MyElixirStatus #ElixirLang

People are really naive about this imo. I think this is the year where at the very least coding agents got strong enough they genuinely are more valuable than entry level engineers for most work

With Christmas and New Year’s coming up a small reminder that I run lettertoyourself.com which lets you send yourself a physical letter in the future. It’s a great way to send yourself some self-love in the future.

We're almost ready for the beta launch! 🎉 #ElixirLang

What I love the most about using LLMs to code is that even when I’m half-braindead, tired, or exhausted, I can still be productive. It takes much less energy to prompt than to write code, especially the boilerplate glue code in between. Absolute game changer.

Saturday mornings are set aside for writing "Financial Analytics Using Elixir". And I must say....I'm really pleased with how the analysis framework is coming together 😍. @livebook.dev and its supporting tooling is such a nice fit for this! #ElixirLang #MyElixirStatus

Yesterday's Nerves Meetup EU had a great talk by @fhunleth.bsky.social about his work on try_boot/autoboot. Automatic reverting of bad firmware on RPi is the point. The video is already up! youtu.be/7zfydKoe5nY #nerves #elixirlang

Elixir Radar now uses my OGI library to generate its Open Graph images 🤘 github.com/PJUllrich/ogi

If you're interested in Nerves, you really don't want to miss this one! This is the last Nerves Meetup EU for 2025, and as a special thank you for helping us kick off the meetup this year, we have a special event planned tonight. Come and join us on Zoom at 19h CET! #ElixirLang #Nerves

This is the most batshit conference presentation I've ever been part of. Zach announces something for Ash, as per usual, but let's just say that's mostly the backdrop.. goatmire.bold.video/v/e37me #goatmire #elixirlang

How can we make AI workloads more sustainable? 🌱 We partnered with Soluna to build real-time systems in #Elixir that match renewable energy with compute demand - powering the future of green AI. Check out how we did it 👉 alembic.com.au/case-studies...

It's been another month already! That means it's almost time for another Nerves Meetup EU - join us tomorrow, Wedneday Dec. 10th at 19h CET for a presentation by @fhunleth.bsky.social about rolling back failed firmware upgrades using tryboot! #ElixirLang #Nerves nervesmeetup.eu/meetup/frank...

Nice! The Elixir survey for 2025 got >1000 respondents. Not too shabby! elixir-hub.com/surveys/2025 #elixirlang

If I ever had to ditch Elixir for another language, I’d choose Rust. It’s such a delight to write, at least for the low-to-medium complex programs I’ve built so far.

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

Just discovered a framework for writing terminal user interfaces in Elixir. What should I build? #MyElixirStatus github.com/pcharbon70/...
