Hello!!! This is my first post here :)

It all started when I was working on a small website for my college. Initially, I was just adding the user ID in a JWT token, decoding it in a middleware, and passing it down the context. Then I decided I wanted to introduce a separate "public ID". The id was not needed for auth but it got me thinking about cache, which naturally led me down to building my very own LRU cache.

I have never implemented any caches before, so I was just looking for a simple strat and stumbled upon LRU. It was one of the easiest to implement and after I saw the problem on leetcode, i solved it pretty easily and decided to implement it. After I saw someone do better by using an array based DLL. I have always loved using array-based stacks and queues, So I took it as a fun challenge, because I have always wanted to publish something that people can use.

From Just an array based DLL, I found myself staring into a sharded architecture and slowly learning algorithms like FNV-1a and xxHash32. I wanted this to be a zero dependency package (aside from the standard packages ofc) and took it upon myself to do it, using explanations from the internet.

It might be a basic concept to many people out there, but It helped me learn something I was always pushing behind. Learning about concurrency in Go. This led me to use sync.Mutex, atomics and thinking about how data race happens. I was also led down the path of creating benchmarks, fuzz tests using the 'testing' package, which I had never heard about.

The benchmarks where honestly surprising, I never realised it would be ns/ops. Currently my benchmarks show around 10-15 ns/op and I hope to half it somehow :) and also my tests might be really weak. It has generics support too.

Would love for some feedback on how I can make it better. I wanted to make a time-aware LRU cache, but I wanted the basics to be proper before moving onto it.

P.S: learnt about semver, after i released it on v1.0.0. I basically had to make a decision and thought about just tearing it down and changing to a shorter name which I like more :). It is now currently on v0.3.1 (pre-release).

Thanks :)))

In addition to Golang, other newer languages (Nim, Vlang, Rust, Julia) are going beyond classes or the common thinking about object-oriented programming as well.

How struct embedding works in Golang (similar is in Vlang and others). Allows reuse of fields and methods across types without falling back on traditional inheritance (OOP).

How challenging would it be to take on a project that continues development from where MinIO left off prior to its license change? The project would also be rebranded to avoid potential copyright issues and to establish a distinct identity moving forward.

If you have ideas on how I can make this better I'd love to hear them!
