I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.
These are the steps I went through to set up an SSL cert.

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.
Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.
You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
Download and install right version of ghostscript. In my case my PHP was x86 architecture, so I download Ghostscript 9.14 for Windows (32 bit).
Psql is a fully-fledged CLI client for Postgres, but most people are unaware of its many advanced features.
~/.psqlrc can be edited to persist any behavior or configuration settings you want between psql sessions. It behaves just like ~/.bashrc or ~/.vimrc, sourced at psql launch. See More out of psql for some interesting configurations.
If you have a long query to write and rewrite, you can use \e to edit your query in an editor.
Use \watch at the end of a query in order to automatically re-run the query every few seconds - great for monitoring while making changes elsewhere in your application architecture.
