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. …

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. …

Crystal is a general purpose, statically-typed, object-oriented, and compiled programming language coming from Manas Tech. The language has been in development since 2014 (for about 6 years now) and the most recent language version is 0.35.1. While everyone eagerly waits for the official release of version 1.0 of Crystal, I…

In this article, I will focus on creating a data ingestion and processing pipeline for Elixir using Broadway [1] library. As per Broadway’s github page, this library is used to — “Build concurrent and multi-stage data ingestion and data processing pipelines with Elixir. It allows developers to consume data efficiently…
