# LODA-RUST mining on a raspberrypi

Warning: `LODA-RUST` mining is highly experimental.

Please let me know about issues you may encounter, or ideas for improvement.


# Installing LODA-CPP - used by LODA-RUST

I'm following [this install guide](https://loda-lang.org/install/).

```
euclid@raspberrypi:~ $ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/loda-lang/loda-cpp/main/install.sh)"
===== Welcome to LODA v22.11.22! =====

This command will guide you through its setup.

Enter the directory where LODA should store its files.
Press return for the default location (see below).
[/home/euclid/loda] 

We recommend to add the following line to your shell configuration:
export PATH=$PATH:/home/euclid/loda/bin
Do you want the setup to add it to /home/euclid/.bashrc? (Y/n) 

Done. Please run 'source /home/euclid/.bashrc' after this setup.
Press enter to continue the setup.


LODA needs to download its programs repository from GitHub.
The repository requires around 350 MB of disk space.
Checking whether git is installed:
git version 2.30.2

Press return to download the default programs repository:
[https://github.com/loda-lang/loda-programs.git]

Updating files: 100% (109788/109788), done.

LODA supports the following modes for mining programs:

1. Local Mode: mined programs are stored in your local
   programs folder only.

2. Client Mode (default): mined programs are stored in
   your local programs folder and also submitted to the
   central API server at https://loda-lang.org.

3. Server Mode: process submissions from the central API
   server and integrate them into the global programs
   repository.

Choose your mining mode:
[2] 

If you want to mine programs, LODA can automatically add
your name as a comment in the mined programs. If you specify
your name and run the miner in client mode, you give consent
to submit mined programs with your name and to publish them
at https://loda-lang.org and the programs repository at
https://github.com/loda-lang/loda-programs.

Enter your name, or "none" to not include it in programs:
[none] Simon Strandgaard (raspberrypi)

To estimate the required server capacity, the LODA miner
can send basic, anonymous usage statistics. Specifically,
a running miner instance would send the value 1 to the
API server once per hour. This data is used to determine
the total number of active miners. There are no IDs or other
data sent to the server. You can still mine without it.

Do you want to send this basic usage statisics? (y/N) y

Configure advanced settings? (y/N) 

===== Setup complete. Thanks for using LODA! =====

To run a Hello World example (Fibonacci numbers):
  loda eval A000045
To mine programs for OEIS sequences (single core):
  loda mine
To mine programs for OEIS sequences (multi core):
  loda mine -p

# Installing Rust language - used by LODA-RUST

I'm following [this install guide](https://www.rust-lang.org/tools/install).

```
euclid@raspberrypi:~ $ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

  /home/euclid/.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  /home/euclid/.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

  /home/euclid/.cargo/bin

This path will then be added to your PATH environment variable by
modifying the profile files located at:

  /home/euclid/.profile
  /home/euclid/.bashrc

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:


   default host triple: aarch64-unknown-linux-gnu
     default toolchain: stable (default)
               profile: default
  modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, run:
source "$HOME/.cargo/env"
euclid@raspberrypi:~ $ source "$HOME/.cargo/env"
