Sometimes you need to keep two upstreams in sync with eachother. For example, you might need to both push to your testing environment and your GitHub repo at the same time. In order to do this simultaneously in one git command, here's a little trick to add multiple push URLs to a single remote.

Once you have a remote set up for one of your upstreams, run these commands with:

git remote set-url --add --push [remote] [original repo URL]
git remote set-url --add --push [remote] [second repo URL]

Once set up, git remote -v should show two (push) URLs and one (fetch) URL. Something like this:

#!/bin/bash
# Usage
# $ ./install-cert-macos.sh "/path/to/cert"
CERT_PATH="$1"

# First, grab the SHA-1 from the provided SSL cert.
CERT_SHA1=$(openssl x509 -in "$CERT_PATH" -sha1 -noout -fingerprint | cut -d "=" -f2 | sed "s/://g")

# Next, grab the SHA-1s of any standard.dev certs in the keychain.
# Don't return an error code if nothing is found.

There are many types of caching that will improve website performance. Here are just five:

MySQL query caching

Every read query that Symphony executes is cached by MySQL. It is important to understand that this is not the result of the query, but the SQL statement itself. MySQL retains a pool of these statements so that they are quicker to execute in the future. This is pretty standard, and you can use it in your own applications too by using SELECT SQL_CACHE for your read queries.

Object caching

Once the database has been queried, the results are used to build objects (pages, data sources, sections, field, entries etc.). These objects are alive only for the lifespan of each page, and are destroyed at the end of each request. Systems such as Wordpress allow these objects to be cached and persisted between each page request (using APC, Memcache, flat files or MySQL), thereby shared between all users. Symphony doesn't do this, but it really should.

Fragment caching

If you have one piece of a p
