Elixir and Erlang are functional programming languages both running on BEAM virtual machine. Programs in both languages get compiled into BEAM byte code. It’s possible to call Elixir code from Erlang and vice versa. …

Amber is a web development framework for Crystal programming language. It uses Granite as its default ORM. While Granite works, I think Clear is more feature rich if your database choice is PostgreSQL. I wanted to integrate Clear ORM with Amber and give it a try. …

In the previous article, I focused on storing nested trees as Merkle trees so that egit can store nested directories. In this article, I will focus on writing building index so that in subsequent articles we can store changes incrementally in repository. A Bit of Theory Git Index is used to provide cache of…

In the previous article, I focused on making history and storing executables in repository. In this article, I will focus on storing nested directories in repository by building nested trees as Merkle trees[5]. A Bit of Theory Git stores nested directories as nested trees and each tree is a Merkle tree. From wikipedia definition…

In the previous article, I focused on storing trees and our first commit. In this article, I will focus on making commit history and storing executable files. A Bit of Theory Git maintains commit history by linking the latest commit to its parent commit, thereby, building a commit history. …

In the previous article of this series, I focused on initializing repository and storing blobs for file content. In this article, I will focus on storing trees and first commit. A Bit of Theory As explained in previous article, a tree stores certain information about the stored blobs. It is one more level of…

I recently got hold of this book Building Git, written by James Coglan. It’s a pretty thick book covering, as the title says, building Git version control system using Ruby programming language. I thought it would be a fun exercise to implement Git using Elixir as I read the book…

In the first part of this article series, I focused on comparing Crystal and Go’s concurrency from Communicating Sequential Processes (CSP) perspective. This second part is to fill in the gap and cover more traditional Shared Memory Multithreading. I make the assumption that you are somewhat familiar with the concepts…

In my previous article on Crystal Programming Language titled — “A First Look at Crystal Programming Language and its Ecosystem”, I wrote about my first experience with Crystal language and its ecosystem. Since then I tried to delve a bit more in Crystal’s syntax and semantics. …
