Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

Oculus Rift + Vive Trackers setup

It's recommend to use the Vive Trackers 2018 since they have less interference with the Oculus Touch controllers. Also some of the steps are only necessary for the moment because of some bugs and broken tools.

I recommend you to join this Discord server if you have any questions: https://discord.gg/bkRgTVw. You can also check this document for fixes to some common issues.

Written by Ind3x. Thanks to Dj Lukis.LT and Kaori for several additional hints.

1. Install SteamVR, start it and finish the tutorial if necessary
2. Open the file Steam\config\steamvr.vrsettings with Windows' Notepad and add the following to the beginning of the steamvr section. Click here to see a short video on how to do that.

If you want to use multiple dbs at once there are several different ways... 

1) If you want to do this on a per-model level, use .store_in (This is for all threads):

class Band
  include Mongoid::Document
  store_in database: "secondary" # This can be any name you want, no need to put it in the mongoid.yml.
end

class Artist
