Well, I am late to the party. Haven't been able to focus lately, but here it is. https://github.com/scriptnull

Siddarthan Sp nice read. Its good to observe, how companies are using their own products to solve their problems. Buddy seems to be interesting. Its really kind of them to give out "Buddy Go" for free. I will try out Buddy, when in need !

This is classic. I do spend sometime for taking look at very old code written by me, whenever possible.

Very tempting question. I can't stop with one. I will share all the code bases I want to explore and the reason behind it. I am lucky, as some code bases in my list are open sourced. Digital Ocean - One of the cleanest products with perfection in every inch of its design. I just love using this product and I am sure a lot of developers too ! A clean product means a clean architecture. A clean architecture means clean code. So, I am sure that I will learn a bit of what simplicity really is by going through their code base. Gitlab ( Open Sourced ) - Fast growing software development platform. These guys are giving a tough competition for its competitors Github . The reason why I want to explore gitlab instead of github is: gitlab is iterating and bringing out features at a very fast phase. The reason for this might be the way they are collaborating and the sanity in code. Vastness in features ( Like CI , pipelines, etc. ) might help learn a extensible architecture Telegram - Favorite messenger. Fast and secure. I am sure that lot of cool things like MTProto are being done in their code base. I would like to spend time reading about those architectures and their code implementations. And from their API docs, I guess that their backend service contains functional programming language ( most probably erlang :: correct me, if i am wrong here). It would be nice to read the source of an app that is written with functional language and running at this scale. Some companies, have open sourced some parts of their codebases. Here are somethings, that I want to spend time in going through. Hashicorp - DevOps Delivered, the right way. Industry leaders with amazing tools that are open sourced. Square - Square played major role in teaching me how code can be written cleanly. They have excellent libraries written in java and made me to realize, how code in production can be written. My personal favorite is retrofit Docker - Have gone through some parts of their codebase as part of my day job. Things really are straight forward here. I would like to take time and get a full picture of things going on here ! and many more.
