void in Java and Void in Haskell are quite different. As the post explains, in Haskell it’s a type with no possible values. In Java, the equivalent would be a class without a constructor (not sure if that’s even possible). It defines a type, but you cannot construct a value or object with that type. The equivalent of Java‘s void in Haskell is the unit type () which has exactly one possible value, also called (). It can be returned by a function, but it does not give you any information, just like void. By the way, Rust also uses the unit type instead of void.

I’ve first read this post back in 2019 when it was released and I have to say that it really has left quite an impact on the way I write programs these days. The „make illegal states unrepresentable“ and „push proofs up“ guidelines are so simple yet so effective. Sure, there is some initial cost to create new datatypes, but it really pays off in the long run. Not having to worry about null or wrongly shaped data structures down the line is really nice, especially if you’re working on older code or develop in a team. Even though the post uses Haskell to explain the concepts, I found it to also work well in other languages, even Java or Python.
Speak for yourself.
Maybe try out Orion Browser. It has built-in ad-blocking and reliably gets rid of YouTube ads.
I have been using Orion Browser (by Kagi) for the last couple of weeks and haven’t seen a single ad on YouTube since.
What‘s the deal with the Cupra logo on the packages?
Orion Browser also has a built-in ad-blocker that also gets rid of Youtube ads. It even has some support for Firefox extensions, including uBlock Origin.
In Firefox, you can also override right-click capture by holding shift while right-clicking.
Is that you, Werner Herzog?
That’s what you get for writing your thesis using Word.

I’ve visited Myanmar for vacation some years before the last military coup. The people were so very friendly and welcoming, it was a real pleasure. I’d like to come back some day. It’s such a shame that the civil war broke out after the country has stabilized somewhat.
