This note explains how to build Postgres from source and setup to debug it using LLDB on a Mac. I used this technique to research this article:
http://patshaughnessy.net/2014/10/13/following-a-select-statement-through-postgres-internals

1. Shut down existing postgres if necessary - you don’t want to mess up your existing DB or work :)

$ ps aux | grep postgres
pat               456   0.0  0.0  2503812    828   ??  Ss   Sun10AM   0:11.59 postgres: stats collector process

Steps to migrate from SVN to GitLab

This process worked for me. I take no responsibility for any damage or loss incurred as a result of following or not following these steps or, for that matter, anything else you might do or not do.

Setup

• SVN is hosted at svn.domain.com.au.
• SVN is accessible via http (other protocols should work).
• GitLab is hosted at git.domain.com.au and:

Friend-or-Foe Relations in the Middle East

Yesterday night, I stumbled upon yet another interesting graph:

The "interactive" version of this image can be found on on this website: they basically try to interactively visualise the interplay of parties that are intervening in the many conflicts currently happening in the Middle East. It’s very, very well done.

So I did a little digging, and found that the original data is in a google doc that you can find over here. Look at the second tab: it’s basically an adjacency matrix of relationships between parties. In other words: a graph.
