I hope there aren't that many codebases still stuck on Scala 2.12 (@twitter 😉), but if yours is, this is a great resource to read. While it focuses on Spark, honestly, anyone making the jump to 2.13 will find it incredibly useful. It covers everything from essential compiler options and helpful plugins to the subtle changes in the standard collections library. #scala #spark #migration

F# 9 introduces auto-generated "is" properties for "enums", enabling checks like .isPhone or .isEmail. While convenient, consider minimizing boolean usage in your code. Boolean logic is error-prone and difficult to read and maintain. Always use proper domain types (On/Off, Valid/Invalid, ...) together with pattern matching for improved readability and type safety. #fsharp #boolean #cleancode

Quick tip💡 The best way to learn Vim motions is by refactoring your code. Try moving a function and updating all its calls, renaming variables, moving code blocks, etc. The more you use them in real-world scenarios, the faster you'll become. #vim #coding

IntelliJ rocks! The new version of the Scala plugin is out, with support for named tuples, better recognition of opaque types, optimisations in compilation, and more. #scala3

While Kotlin offers improvements over Java, Scala's focus on immutability and functional programming can lead to more reliable and maintainable systems in the long run. It might be worth skipping the intermediary step and going straight to Scala for those benefits. #java #kotlin #scala @npub1fsvd...y05d

Why Should Your Company Consider Switching from Java to Kotlin | SoftwareMill

In this blog post, we’ll explore why your company should consider switching to Kotlin, especially for web development projects.

There's a special place in silicon heaven for libraries without external dependencies. #scala3

𝕏 just open-sourced another Scala library, but it's still on Scala 2.12! 🐦 As an early adopter, they've probably got a ton of legacy code and know how tricky Scala migrations can be. Great to see they're still committed to Scala after all these years! #scala #twitter #x #opensource

Even if you don't prefer direct-style Scala (i.e., function coloring is a feature for you, not a bug), I recommend watching a walkthrough video about the Ox library, grinded in the SoftwareMill. #scala3 #projectloom

Migrating to Scala 3 is much easier these days. Did you know that there's a compilation flag (-Ytasty-reader) that allows you to compile and use your Scala 3 libraries in a Scala 2.13 codebase, giving you access to new features? #scala3 👉

It's so convenient now to write simple scripts thanks to Scala 3, scala-cli, and Li Haoyi's os-lib. This particular script, for instance, simply created exact copies of a bank logo with different names. #scala3

This video serves as a reminder of the importance of rigorous testing and the responsibility that comes with writing code. It's difficult to watch to the end, knowing the tragic consequences. #qa #bugfixing #codereview #testing

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

I hope you're all aware by now, but there was an incident a couple of days ago while releasing an RC version of Scala Next. Please read the official statement and don't use Scala 3.6 in production code! #scala3 #incident
