Seriously, if you're a programmer, you should definitely try home row mods ⌨️ Ideally pair them with any keyboard with columnar layout (like the #Voyager). Trust me, your fingers will thank you. 👐 @dreamsofcode_io #coding #keyboards #lifehacks #typingtips

That's a very good take on the superiority of FP. It's important to remember that skill varies in any paradigm, but at least my experience suggests that strong programmers are more common in the functional community. 🤷‍♂️ #functionalprogramming

It's impressive to see so many new libraries being written directly in Scala 3! ❤️ Peloton, an actor library built for Cats Effect, is a great example. #peloton #scala3 #actors #cats

It begins innocently - as a simple regex. Then a quick pattern here, a minor tweak there. Over time, you're left with an indecipherable string of characters that no one can understand. Next time, consider using a parser! 💪 #scala3 #parsers

Imagine writing plain SQL, and a tool generates structures and repositories for you! 🤯 It's like an ORM, but the other way around. ♻️ What an interesting idea! Sadly it's only for Go now. #sql #sqlc #go #orm
