In my proposed lightning talk for the Reactive Conference, I'll create Conway's Game of Life in ClojureScript, and I'll do it in five minutes. I'll use an interactive programming workflow enabled by Figwheel. Each piece will be added into the running application without reloading the page.

If you want to see a little cellular lifeform spawn out of nothing into an running web browser window, I'd appreciate it if you starred this Gist!

Cheers,

React (Virtual) DOM Terminology

In React's terminology, there are five core types that are important to distinguish:

• ReactElement / ReactElement Factory
• ReactNode
• ReactComponent / ReactComponent Class

OBSOLETE

This entire guide is based on an old version of Homebrew/Node and no longer applies. It was only ever intended to fix a specific error message which has since been fixed. I've kept it here for historical purposes, but it should no longer be used. Homebrew maintainers have fixed things and the options mentioned don't exist and won't work.

I still believe it is better to manually install npm separately since having a generic package manager maintain another package manager is a bad idea, but the instructions below don't explain how to do that.

Fixing npm On Mac OS X for Homebrew Users

Installing node through Homebrew can cause problems with npm for globally installed packages. To fix it quickly, use the solution below. An explanation is also included at the end of this document.

How to add syntax-highlighted code to PowerPoint slides (Mac OS)

1. pygmentize -f rtf FILE | pbcopy
2. Paste into TextEdit (in rich text mode: Format → Make Rich Text before pasting), and copy to clipboard again.
3. In PowerPoint, Edit → Paste Special… → Styled Text.

(Pasting RTF directly into PowerPoint doesn't work correctly, at least with PowerPoint 2008 — it extends colour spans longer than it should, and sometimes removes line breaks. Going via TextEdit seems to solve the problem.)
