Create video screencasts using recordmydesktop

Why make a video screen capture, aka screencast? Some possible reasons are:

  • Create a software demo.
  • Capture a video game session for playback later.
  • Keep a record of what transpires on the computer screen.

I create screencasts mainly for recordkeeping. As a result, I don't expect to edit the output video, for example, to obfuscate sensitive data, or to insert call-outs to draw attention to specific screen areas.

Goodbye UW IMAP! Hello Dovecot! Oracle Solaris 11 setup guide for Dovecot

After many years of being faithful to UW IMAP it was time to move on. The move was required since UW IMAP was no longer being supported and I was having problems using it with latest version of Horde Webmail, so I decided to install Dovecot on our Oracle Solaris 11 systems.

I was surprised how easy the installation went to get Dovecot working on Solaris 11, which was pleasing.

Python – remove newline from readlines

 
readlines() is a function in python used to read text file and convert it into list where each line in at file is a element in list with new line(\n) at the end of each element.
Example:
>>> filelist = open("file.txt").readlines()
['a\n', 'b\n', 'c\n', 'd\n']
If you want to remove new line(\n) at the end of all elements in list use read() and splitlines() functions as shown in below example.
