Months of work went into this and I finally saw it live in production. From queries that used to take 15+ seconds (and timed out) to just ~10-30ms 🚀 More details in the design doc: handbook.gitlab.com/handbook/eng...

Now that Strava has launched a similar feature, I'm ready to show you the project I've been working on this year: easyhard.carbonative.com It will help you to obey the 80/20 rule in running: 80% of your runs should be easy, 20% hard.

I am building a small application with #ElixirLang and Codex. Process is pretty much: - Let Codex run with my prompt - Look at generated code - Delete 50% of the code It's okay-ish at writing tests, which is nice. Especially since IMO Elixir tests are too verbose compared to RSpec.

Looked more into @ash-hq.org now. A few thoughts - Not completely sold on the declarative style. - It's fast to prototype stuff. - LLMs are doing surprisingly ok. - Having types end to end is a game changer.

Ruby community reaches JavaScript community drama level.

I looked into Node/Typescript ecosystem for a Fullstack framework last week. Quality on the backend is just too far off from what I see in Rails/Phoenix. My biggest requirement is: full typing between backend to frontend. Now looking into @ash-hq.org 👀

I am looking into the NodeJS ecosystem. A bit shocked about the state of ORMs. Maybe it's what I needed to appreciate ActiveRecord 😂

After being a drummer all my life, it still blows my mind that I can take my Trombone WITH ME. Disassemble. Put it in the case. Go Just like that 🤯

What are good open source Elixir/Phoenix codebases to look into? I already looked into @changelog.com and like that they're cutting out context completely.

Our GitHub repository is now public! github.com/elixir-lang/...

"What do you hate about ActiveRecord?" That interview would definitely go over time.

So far I've not seen any good fullstack framework. JS does well on client/server communication, but is years behind backend frameworks. Backend languages try to abstract all client-side communication and end up with weird patterns.

Experience means: you hate all your solutions equally.

I blogged again nicolasdular.com/blog/2025/06...

I am getting SO tired of these posts from influencers: “We literally cloned an N billion-dollar company in 20 minutes with {vibe coding tool}. This changes the game forever.” No, you didn’t “clone” a billion-dollar business. You created a landing page similar to it. That’s all.

This! spiess.dev/note/enginee...

Most SaaS products are just fancier Excel sheets. Dedicated software is still nicer to use though. But with AI, I expect more companies starting to build tailored tools themselves.

I love that they work on type inference. Interops from BE to FE is the missing piece. Looking forward to when this is solved!

It feels like we got MCP two days ago and now there’s conferences being announced for it I cannot keep up

What we wanted: Productivity tools to help us focus. What we got: Distractions everywhere.

I am happy for the penguins. They now have 90 days to recover from that shock

Remember when the biggest Monday problem was avoiding Game of Thrones spoilers? 😄

The Sculpt Keyboard is the only one that works for my hands. But they stopped producing it. Which was scary. However, Kinesis ships a new keyboard with the same layout this year 😍 kinesis-ergo.com/keyboards/mw...

Submitted my talk for 2025.euruko.org 🤞

"5 years in the making" -> good things take time! And this is really good!

I am happy to say the "Followers only" reply setting is getting implemented. We're also adding a way to set default reply settings If you want your posts to default to "Followers only," that'll become an option

of course they built it lumon-industries.com

Poll: What's your opinion on an API that returns a mix of negative and positive integers for IDs ? It would allow us to remove a bunch of complexities, while not breaking the API contract.

There is a position open in our team! The Plan section is pretty cool as we have some unique technical challenges. If you have any questions, my DMs are open. ☺️ #Ruby #RubyOnRails job-boards.greenhouse.io/gitlab/jobs/...

What a neat idea with the `@job` tag 😍 oban.pro/releases/pro...

I started learning a new instrument - yay! But it reminded me again how most tips and tricks you can find online are just not enough. Don't skip your own learning process. nicolasdular.com/blog/2025/01...

Computer Science at university: write about ethics of using AI. Think about trolly problem etc. Real world: „We now just use AI for interviews“

Just three social media CEOs posting on their platform today.

I resurrected my old side project sweatmaps now under a sub-domain. sweatmaps.nicolasdular.com/show/gvLOkLRQ It's more complex than it looks like as multiple services are involved. Lesson learned: don't hardcode your domains 😂

It's not pretty - but it works 🎉 Players can join a game, set topics (or generate them) Then questions from these topics get generated and show up. First player with the correct answer wins the question. All via synced via LiveView/PubSubs #ElixirLang

PTO started: switching from Ruby to #ElixirLang 😃 Another attempt to build a game in my Christmas holidays.

EM: Who is covering for you on PTO? Me: A feature flag

Not sure how long I sustain Advent of Code as I am really tired from this year. But.. it's so nice to solve something every day. Without caring about other factors, changes of priorities or scope.

Day 3 of Advent of Code completed. Nice usage of LLMs: 1. Solve it without AI first 2. Ask to make it "smaller" or "nicer" Helps me to discover new functions in the standard library.

This year in Elixir! Let's see how far I come... I just completed "Historian Hysteria" - Day 1 - Advent of Code 2024 #AdventOfCode adventofcode.com/2024/day/1

I’m thankful for everyone using Bluesky, everyone building on atproto, everyone listening to our message and sharing our dream of a better social media ecosystem that puts people first. We’re going to do this together — thanks for joining us on this journey!

🚨🚨🚨 Today I'm asking for your HELP! 🚨🚨🚨 This summer, I joined "Canisibike", an initiative of Caritas Austria (link in comments). Every day, our team of volunteers brings hot soup 🍜 and an open ear to those in need (often, the conversations seem more important) – by bike 🚲 , in Vienna. [1/n]

This has been so much fun to work on with the team, definitely try it out and give us feedback! My favorites: - The new first-class Vite plugin as it's so much faster in dev mode - P3 color defaults and oklab/oklch gradiant modifiers - The fact that I can upgrade my v3 projects with one command 🤯

One side projects I am working on is an RSS reader with a social component. Maybe Bluesky could be a part of that. I am thinking about custom feeds or connecting comments to a post 🤔
