| After automatically updating Postgres to 10.0 via Homebrew, the pg_ctl start command didn't work. | |
| The error was "The data directory was initialized by PostgreSQL version 9.6, which is not compatible with this version 10.0." | |
| Database files have to be updated before starting the server, here are the steps that had to be followed: | |
| # need to have both 9.6.x and latest 10.0 installed, and keep 10.0 as default | |
| brew unlink postgresql | |
| brew install postgresql@9.6 | |
| brew unlink postgresql@9.6 | |
| brew link postgresql |

Custom recipe to get OS X 10.11 El Capitan running from scratch, setup applications and developer environment. This is very similar (and currently mostly the same) as my 10.10 Yosemite setup recipe (as found on this gist https://gist.github.com/kevinelliott/0726211d17020a6abc1f). Note that I expect this to change significantly as I install El Capitan several times.
I use this gist to keep track of the important software and steps required to have a functioning system after a semi-annual fresh install. On average, I reinstall each computer from scratch every 6 months, and I do not perform upgrades between distros.
This keeps the system performing at top speeds, clean of trojans, spyware, and ensures that I maintain good organizational practices for my content and backups. I highly recommend this.
You are encouraged to fork this and modify it to your heart's content to match your own needs.
When developing a program in Ruby, you may sometimes encounter a memory leak. For a while now, Ruby has a facility to gather information about what objects are laying around: ObjectSpace.
There are several approaches one can take to debug a leak. This discusses a time-based approach, where a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up. Afterwards, one can look at all the objects, and find out which ones are staying around, causing the

With Ruby 1.8 (default version on MacOS) :
sudo gem install json
curl -s https://api.github.com/orgs/[ORGANIZATION]/repos | ruby -rubygems -e 'require “json”; JSON.load(STDIN.read).each {|repo| %x[git clone #{repo["ssh_url"]} ]}'
With Ruby 1.9+, the json library is by default thus you just use :
