Tomorrow is a SysAdmin appreciation day. The holiday exists to show appreciation for the work of sysadmins and other IT professionals. It is celebrated on the last Friday in July i.e. Friday, July 27, 2012, is the 13th annual System Administrator Appreciation Day.
This celebration’s aim is to acknowledge the effort that sysadmins perform every day of the year 24×7. I hope that all sys admins have a nice day on Friday and get a little less hassle than normal. AdminFest is hosting a party to celebrate the SysAdmin appreciation day. Check out promotional videos here.
