Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...

	#!/bin/bash

	MONGO_DATABASE="your_db_name"
	APP_NAME="your_app_name"

	MONGO_HOST="127.0.0.1"
	MONGO_PORT="27017"
	TIMESTAMP=`date +%F-%H%M`
	MONGODUMP_PATH="/usr/bin/mongodump"
	BACKUPS_DIR="/home/username/backups/$APP_NAME"

	//SearchController.php
	public function autocomplete(){
	$term = Input::get('term');

	$results = array();

	$queries = DB::table('users')
	->where('first_name', 'LIKE', '%'.$term.'%')
	->orWhere('last_name', 'LIKE', '%'.$term.'%')
	->take(5)->get();

	function get_avatar_from_service(service, userid, size) {
	// this return the url that redirects to the according user image/avatar/profile picture
	// implemented services: google profiles, facebook, gravatar, twitter, tumblr, default fallback
	// for google use get_avatar_from_service('google', profile-name or user-id , size-in-px )
	// for facebook use get_avatar_from_service('facebook', vanity url or user-id , size-in-px or size-as-word )
	// for gravatar use get_avatar_from_service('gravatar', md5 hash email@adress, size-in-px )
	// for twitter use get_avatar_from_service('twitter', username, size-in-px or size-as-word )
	// for tumblr use get_avatar_from_service('tumblr', blog-url, size-in-px )
	// everything else will go to the fallback
	// google and gravatar scale the avatar to any site, others will guided to the next best version
