At the beginning of 2030, I found this essay in my archives. From what I know today, I think it was very insightful at the moment of writing. And I feel it should be published because it can teach us, Rust developers, how to prevent that sad story from happening again.

What killed Haskell, could kill Rust, too

What killed Haskell, could kill Rust, too. Why would I even mention Haskell in this context? Well, Haskell and Rust are deeply related. Not because Rust is Haskell without HKTs. (Some of you know what that means, and the rest of you will wonder for a very long time). Much of the style of Rust is similar in many ways to the style of Haskell. In some sense Rust is a reincarnation of Haskell, with a little bit of C-ish like syntax, a very small amount.

Is Haskell dead?

Data-Oriented Design Book Review

Data-Oriented Design (2018) by Richard Fabian

Computers keep getting faster but the future ain't what it used to be. Instead of higher clock rates we get deeper pipelines, higher latencies, more cores. Programming these systems requires paying attention to how we structure and access our data. In Data-Oriented Design Richard Fabian—who has worked at Frontier Developments, Rockstar Games, and Team17—presents us an approach to reason about these issues from a C++ game developer's perspective.

Data-oriented design is about caches and decoupling meaning from data. The former implies laying out your data so that they're compact and predictably accessed. The latter means exposing the raw transforms from one sequence of bits to another. For example, finding the pla

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

What I Didn't Know about Functional Programming until 2020

Programming using a series of transformations and aggregations, something I've been doing for years, is known as programming in the map/reduce style.
The more abstract the type is, the greater its cardinality, and the smaller the set of operations it supports. So make use of universal quantifiers, particularly by implementing fully parametric functions. They guide you on how to implement their term-level definitions by narrowing down the number of possible implementations. In other words, the type system of Scala (or Haskell, for that matter) is not only great for capturing compile-time errors, but is also capable of leading you to the correct solution.
You can encode union types by combining different Scala features such as type constructors, subtyping and implicits, and by taking advantage of the Curry-Howard Isomorphism and De Morgan's Laws for neg

What I Didn't Know about Functional Programming until 2021

A hom-functor is usually implemented in Scala as the reader functor. The type itself is essentially a hom-set, but if we fix the domain to a particular type, we get a functor:
```
// A hom-set Hom(A, X)
type Reader[A, X] = A => X
```

// A hom-functor X => Hom(String, X) or Hom(String, -)
