How to have local versions of tracked config files in git

This is a fairly common question, and there isn't a One True Answer.

These are the most common techniques:

If you can modify your application

Deploy your site with git

This gist assumes:

• you have a local git repo
• with an online remote repository (github / bitbucket etc)
• and a cloud server (Rackspace cloud / Amazon EC2 etc)
  • your (PHP) scripts are served from /var/www/html/
  • your webpages are executed by apache
• apache's home directory is /var/www/

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Install

Either copy the aliases from the .gitconfig or run the commands in add-pr-alias.sh

Usage

Easily checkout local copies of pull requests from remotes:

• git pr 4 - creates local branch pr/4 from the github upstream(if it exists) or origin remote and checks it out
• git pr 4 someremote - creates local branch pr/4 from someremote remote and checks it out

Understanding this in JavaScript

It's easy to trip up on the meaning of this in JavaScript. The behavior is very different from other languages, which means we have to throw most preconceptions and intuition out the window.

The best way to think of this in JS is as a hidden function argument which is passed in a slightly awkward way. Instead of the normal passing of arguments:

fn(arg1, arg2, arg3)

      // the URL below is changed. Any change will invalidate the cache
      var css_href = './index_files/web-fonts.css';
      // a simple event handler wrapper
      function on(el, ev, callback) {
        if (el.addEventListener) {
          el.addEventListener(ev, callback, false);

HOLY GAWD PEOPLE..

• Don't write all your new code on the production machine!
• Use a VCS!
• Document your functions using DocBlocks!
• Document your API (at least LIST the endpoints)... I have to decipher the meaning from your code, and that isn't really clear
• Use a single identifier as the primary ID in the API for a resource (ie don't return a list of group ids for listing groups and then expect the group name as the identifying parameter for modifying a group)
• Use a consistent model for representing the same data model in different endpoints!
• Don't concatenate fields in the API results unless there is a good reason to (e.g first name and last name)
• Don't expose the underlying database logic. This is leaky abstraction, especially when you do it inconsistently!!
