I'm happy to announce that I'm joining @getsentry ! 🎉 I'll be working mostly on Elixir SDK but you'll see me in the Ruby SDK repo too 🙂 I'll be getting involved slowly in July/August as I'm in Family Mode, and then switching to ~full-time in September (1/2) #MyElixirStatus

DHH was not cancelled, he was informed that they want to give another person a chance to give a keynote at RailsConf (for the first time ever, btw). This shouldn't be a big deal. In fact, DHH should've proposed such a change himself by now.

On a related note. People often ask me “how do you that?”, refering to my OSS contributions. Most of them assumed it was part of my work. Well, it wasn’t. Instead of playing with my kids, I was coding. Instead of riding on my bike, I was coding. And honestly, it was a mistake.

Dear young programmers, don't be me and take care of your back early on. Invest in ergonomic workspace, take regular breaks (pomodoro is great), go for a walk every day, stretch daily (yoga is great), *do sports*, be active. Otherwise, things get f*cked sooner than you think.

Reading Elixir code has been (so far) simpler than reading Ruby/Rails code (despite my massive experience with Ruby 🤷). I'm pretty sure you could do all sorts of crazy things that are hard to decipher BUT so far I've been quite surprised that it's so easy to understand things

Every Rails app that I worked with in the past ~3-4 years used JSON stored in the db. In all cases the apps suffered from the fact that this JSON was represented as plain hashes which caused a lot of extra complexity. This can be improved greatly by using gems like dry-struct.

Here's an example of a classic Rails approach that's based on AR validation vs a much more flexible and versatile approach with a dedicated object. Notice that pattern matching on results can easily be expanded to handle more use cases. This syntax is very expressive yet concise.

Job hunt update: now it's more Ruby leads than Elixir. It's hard to find something in general, but it's especially hard if you're after Elixir. At least that's my experience. Things would be much better if I lived in the US of course. I still love and enjoy Ruby but I feel like

📣 You can now sign up for my upcoming course "Data Oriented Web Development with Ruby" on @podia ‼️ Maybe you remember but this was supposed to be a book but I ended up turning it into a course 🙂 If things go well it'll be launched in mid December.

If you hear that company X ported their system from language Y to language Z and it’s now 80% less code and it’s 354% faster then remind yourself that they were in a much better position to build it because they’ve already done it before and they’ve learned their lessons

Just a random reminder that the fact that somebody is an ex-FANG developer doesn't automatically make them exceptional in any way. You can work at a big tech company and do quite literally shit work and learn almost nothing. So, be aware of such "tech/programming influencers".

Don't you feel like the Rails community has been caught in an infinite loop when it comes to talking about arch design in Rails apps? It's the same stuff since 2008 or so. It's like every year people discover POROs, "service objects" (hate that term), callbacks are bad etc.

In general, I find it easy to pick up Elixir as a dev with heavy Ruby background but there's a prerequisite here: you have to understand functional programming first. Otherwise you'll inevitably write weird "Relixir" code and it's gonna take extra time to get things right.
