Ubuntu 12.04: Skype

Skype is a communication essential for my system because I have co-workers who use it.  There are plenty of alternatives to Skype, but none of them interact with other Skypers.

Currently, Skype works for the most part.  I have trouble with it crashing periodically.  The crashes seem to coincide with changing networks.  For example, if I connect and disconnect from a VPN, I find I am offline even though the icon is green.  I am not sure if I just notice it then or if the connection change triggers it.  The worst part is that I can’t tell that it has crashed until I try to Skype someone and it says it can’t send the message.

Ubuntu 12.04: Sound

Sound has been a problem for me in the past.  I found that the sound seems to work slightly better on Fedora than on Ubuntu.  Ubuntu 12.04 has worked better for me, but I think things are still a little more flakey than I would like.  Some of my problems might come from a USB docking station that has a sound plugin and some of the problems definitely come from Skype.

Anyhow, these are the tools that I am currently using:

  • Audacity
  • Sound Settings — switching between devices
  • MuseScore

Checking Files with md5sum or sha1sum

This post will explore the two tools, and give you a quick little intro on how to use them.
