In episode 47 of Thinking Elixir, we talk with Kamil Skowron about his Youtube channel that walks people through building a crypto-currency trading bot in Elixir. We learn how that led him to start a free online book sharing that content. He covers what people will learn from the process, his goal of helping people see a larger working Elixir system, and his experience writing the book. A fun chat!

Hello everyone 👋

Officially this is the most intense/demanding video that I ever released 😀 The video sums up the work over 15 videos released in the series dedicated to “Create a cryptocurrency trading bot in Elixir”. In 12 minutes (excluding intro & outro 😉 ) we will see how a trading bot could be written including a full supervision tree around streaming and trading as well as built-in autostarting for both! It’s a great resource to see the usage of the Elixir/OTP in real-world scenarios.

It’s a great refresher if you want to quickly go through it “once again” or teaser if you are wondering should you invest time in it(according to comments - well worth it 😜). As pointed out in the video, not a lot of in-depth explanations inside - if you are looking for discussion why it’s built the way it is - there are 15 episodes already released on my channel (https://www.youtube.com/watch?v=wVYIx7M6o28&list=PLxsE19GnjC5Nv1CbeKOiS5YqGqw35aZFJ&index=1)

Ever since my friend introduced me to the 7 GUI tasks, I’ve been interested in doing them with LiveView.

I finished the first one (the simplest one 😁) and wrote some highlights. I hope to do the other ones too!

I found out just recently that passing a single SSL option to Hackney overrides any other settings and therefore makes your calls insecure.

In episode 46 of Thinking Elixir, we talk with Jonatan Kłosko, the coder behind Livebook, about how Livebook works, how the collaborative features work, what can be done with Livebook, what you shouldn’t do with it, and much more! We can’t help but talk about all the fun and cool ways it can be abused and how it’s finding exciting uses outside of machine learning. A great discussion with lots of insights.

I created a Jackbox-TV inspired game server system just to see if I could. It’s fully distributed, clustered, and globally deployed. It uses LiveView and PubSub. It is a proof-of-concept that shows how to build multi-player, turn-based games.

I explain how I deployed it to Fly.io as well. This was my first ever deployment on that platform. Check out the Github Repo and the companion article: Building a Distributed Turn-Based Game System in Elixir
