tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

Description

This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.

The script is here:

#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"

agnoster

agnoster.zsh-theme

A ZSH theme optimized for people who use:

• Solarized
• Git
• Unicode-compatible fonts and terminals (I use iTerm2 + Menlo)

For Mac users, I highly recommend iTerm 2 + Solarized Dark

What to evaluate and consider before adding usage of new third-party crates.

These are not exact requirements but questions to investigate and discuss to help reason around the health, safety, maintainability, and more around crates.

This can also be read as an opinionated guide for crate authors of what our (Embark's) guidelines and recommendations are, though should not be taken too literally.

THIS GIST IS OUT OF DATE!  Please use my new project template here to get started with Zig on Playdate:
https://github.com/DanB91/Zig-Playdate-Template


The rest of this is preservied for historical reasons:


This is a small snippet of some code to get you started for developing for the Playdate on Zig.  This code should be used as a starting point and may not compile without some massaging.  This code has only been tested out on macOS and you'll need to modify the addSharedLibrary() portion of build.zig to output a .dll or .so instead of a .dylib, depending on you platform.

This code will help you produce both an executable for the Playdate simulator and also an executable that actually run on the Playdate hardware.

1. Separation of immutable and mutable logic

Quite a lot of different people have been on the same trail of thought. Gary Bernhardt's formulation of a "functional core, imperative shell" seems to be the most voiced.

"Boundaries" - Gary Bernhardt

"Imperative shell" that wraps and uses your "functional core".. The result of this is that the shell has fewer paths, but more dependencies. The core contains no dependencies, but encapsulates the different logic paths. So we’re encapsulating dependencies on one side, and business logic on the other side. Or put another way, the way to figure out the separation is by doing as much as you can without mutation, and then encapsulating the mutation separately. Functional core — Many fast unit tests. Imperative shell — Few integration tests
