Last minute GitHub presentation - 3rd of June

[Josh K]

Hey Guys,

Aman (@tmm1) and Cory (@atmos) are in town, after making it to Euruko
in Berlin, and have offered to give some last minute presentations for
the Amsterdam.rb and wider communities.

Aman will be talking about memprof and perftools, and Cory will talk
on how GitHub develop and deploy features.

The presentations will be held at the Waag, Nieuwmarkt 4, 1012 CR
Amsterdam. (The big castle in the middle of Nieuwmarkt - http://bit.ly/jnxlSV)

Doors open at 5pm, and presentations start at 5:30pm.

Then we will continue to De Bekeerde Suster (to seconds walk away -
Kloveniersburgwal 6, 1012 Amsterdam) for GitHub drinks!

Hope to see you all there,

Josh
