Very cool, congrats on your progress! I started working on similar book ‘Elixir for Business’, but never finished, may be I should get back to it!

Book looks great. I want to like Nx, but my experience with Nx is terrible running over GPUs:
could not compile dependency :exla, "mix compile" failed. Errors may have been logged above. You can recompile this dependency with "mix deps.compile exla --force", update it with "mix deps.update exla" or clean it with "mix deps.clean exla"
Ollama is bomber - never never fails. Nx never works out-of-the-box. The decision to rely on Exla should be revisited. Getting Exla/Nx running is black magic, I’ll bet it has terrible consequences for Nx adoption. A shame Exla installation is so terrible - once beyond that gauntlet the Nx toolchain is super nice.

I have now received it. Interestingly enough I had to switch from a gmail email, to another email client for me to get the sample.

This book seems very US-centric. Having very little knowledge of markets or trading myself, do the ideas in the book extend to other markets/countries? Appreciate that if you don’t have experience with other markets/countries that perhaps you can’t answer this.

In the book we lean on the EXLA and I haven’t had issues with it either on Linux or Mac when configuring the compiler for :host. I have been meaning to try out GitHub - ausimian/emily: Elixir bindings and Nx backend for Apple MLX · GitHub to make use of MLX on my Apple hardware, but haven’t had the chance yet. If I had any CUDA hardware I could probably share your pain

Good question! We focus on US time series data since it is what we easily had access to. I created and published 2 open source libraries to make that easier for book readers (and anyone really that wants to play with stock/economic data):
That being said, the techniques covered in the book can be applied to any stock time series data. So if you have an alternative data source and can massage the data, the techniques covered in this book are just as applicable.

Yes, :host mode is reliable. I hope the MLX backend is successful. The dominance of CUDA is a head-scratcher! Ollama makes it work by embedding CUDA in the app. Bulletproof!! EXLA should consider that approach. Two developments make CUDA/Nx somewhat less painful 1) Ubuntu 26.04 is the first Ubuntu to natively distribute CUDA. sudo apt install cuda - OMG yes! 2) Claude has proven effective at debugging cuda drivers and EXLA compile issues.

Congrats on the new book! Will there be an option to just by the ebook (pdf or epub)? Thanks!
