petehunt / React sortable
Created December 9, 2013 22:30
Here's an example of React + jQuery UI sortable. The key thing to note is that we have the render() method do absolutely nothing and use componentDidUpdate() + React.renderComponent() to proxy updates through to the children. This lets us manage the DOM manually but still be able to use all the React goodies you know and love.

Better local require() paths for Node.js

Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

Reader Macros in Common Lisp

Reader Macros in Common Lisp

This post also appears on lisper.in.

Reader macros are perhaps not as famous as ordinary macros. While macros are a great way to create your own DSL, reader macros provide even greater flexibility by allowing you to create entirely new syntax on top of Lisp.

Paul Graham explains them very well in [On Lisp][] (Chapter 17, Read-Macros):

The three big moments in a Lisp expression's life are read-time, compile-time, and runtime. Functions are in control at runtime. Macros give us a chance to perform transformations on programs at compile-time. ...read-macros... do their work at read-time.
