Embedded Rust on STM32F4

My notes from implementing Job Vranish's excellent guide.

Follow along with the guide above, getting rustc from rustup or similar:

rustc 1.0.0-nightly (dcaeb6aa2 2015-01-18 11:28:53 +0000)
binary: rustc

# Install arch linux in an encrypted btrfs partition with GPT and UEFI support, gummiboot and hibernate/resume support

# Take note of this:
# - The first thing you need is to identify which disk you're going to use. For the purpose of this guide, it will be /dev/sda
#   Be VERY CAREFUL if you have more than one disk on your computer, and DOUBLE CAREFUL if one of them is the one with your backups
# - Since btrfs does not support swapfiles (yet), we'll create a swap partition. In this guide, it will NOT be encrypted

'''This script goes along the blog post
"Building powerful image classification models using very little data"
from blog.keras.io.
It uses data that can be downloaded at:
https://www.kaggle.com/c/dogs-vs-cats/data
In our setup, we:
- created a data/ folder
- created train/ and validation/ subfolders inside data/
- created cats/ and dogs/ subfolders inside train/ and validation/
- put the cat pictures index 0-999 in data/train/cats

# This example using
# Nim: 0.18.0
# Jester: 0.2.1
# Using Jester >= 0.3.0 is preferrable if your Nim version > 0.18.0
# In case you're using Jester >= 0.3.0, look the syntax different
# in its example because it's not backward compatible

Python Versus Nim: Async

• No performance benchmark.
• Python ⟿ PEP-8
• Nim ⟿ NEP1
• Python ⟿ 3.7
• Nim ⟿ 0.19
• No Ofuscation, no Code-Golf.

This is to compare elegant, simple, expressive code.

## Utilities for mixing async/await with threads.
##
## ``threadSafe()`` takes a Future and returns a new Future that can be completed on any thread.
## The original Future's callback will still be invoked on its original thread, and ``await``
## works normally.
