Circumvent Skype’s unable to add contact problem

In my workplace, the internet connection is through a proxy server. With Skype, I was able to talk to people in my contact list, but I was not able to add new contact. The problem and some solutions have been posted in the Skype community forum. However none of the solutions works on my Skype installation. Finally I found a way to add contact:

1. In Skype, go to Contacts -> “Import Contacts”. It will ask you for username and password for the proxy server.
2. Enter your username and password.
3. Now go to Contacts -> “Add Contact”. You should be able to add contact now.

How to tell if the R session you are running is 64 bit or 32 bit?

Under Windows, here is a simple hack to find out whether you are running a 64 bit or 32 bit R.

  1. Type the command version in the prompt.
  2. If you see arch           x86_64, then it is 64 bit. Otherwise, it is 32 bit.
