tmux

Overview

• tmux is a great solution for managing the state of terminal sessions. This allows you to jump between terminal sessions with ease so you can multitask while not losing your work. In addition, the window and pane display functionality allows you to create dashboard-like layouts for your terminal sessions.
• tmux is based around sessions. Sessions can be created, attached, and detached. This allows you to create sessions, detach from them, and reattach to them to pick up where you left off.
• tmux sessions have a zero-indexed number associated with them. This serves as a identifier that's used to reattach to an existing session. They can also be named to give context.
• tmux windows are contained within a session. A session can have one or many windows. A window is a grouping of panes. Like sessions, windows are also numbered or nameable.
• tmux panes can be used to run commands, monitor processes, tail logs, etc.

Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

Install Atom

Download Atom

The Atom documentation is excellent. It's highly worth reading the flight manual.

AngularJS Directive Attribute Binding Explanation

When using directives, you often need to pass parameters to the directive. This can be done in several ways. The first 3 can be used whether scope is true or false. This is still a WIP, so validate for yourself.

1. Raw Attribute Strings

   <div my-directive="some string" another-param="another string"></div>

• An alternative approach to RESTful APIs
• Clients issue queries/mutations to read and update data
