QFM126: Elixir Reading List - August 2026

A pair of links, each taking Elixir somewhere it is seldom the first choice. Elixir For Finance takes it to the quant's desk, ground that Python usually holds, with Dimitrios and Alexander Koutmos teaching the markets through analysis you write yourself; the book is in early access, with more chapters to come.
Sloppy Joe takes it to the phone, where your own coding agent does the building and the name gets its joke in first. Underneath runs GenericJam's mob, the BEAM-on-device framework that has been on this list twice before, and this time it is carrying an app you can install.
As always, the Quantum Fax Machine Propeller Hat Key will guide your browsing. Enjoy!

Sloppy Joe is a deliberately blank phone app that your own coding agent turns into whatever you describe. You connect the agent through an MCP server with a pairing code and describe the app in plain words; your prompts stay on your machine, and the code is tested on Joe's own devices before the build reaches your phone. Its Operator mode puts a coding agent on the phone itself, with every change waiting for your fingerprint, face or PIN and new code that undoes itself if it keeps crashing. It is in this list because, as the Operator page puts it, the same mob framework is underneath: GenericJam's BEAM-on-device mobile stack, which made the May 2026 list (QFM114).
Elixir For Finance is a developer guidebook to financial markets in which you learn the finance by writing the Elixir: fetching economic data from the FRED API and market prices from Yahoo! Finance, measuring portfolio risk and return across stocks, crypto and commodities, and building technical trading indicators to backtest against market history, all in Livebook with Explorer, Scholar and Nx. It is written by Dimitrios Koutmos, tenured faculty at Texas A&M working in quantitative finance, and Alexander Koutmos, author of Elixir Patterns, and it is in early access: five of its seventeen chapters and eleven Livebook notebooks are out, with the rest to follow.
