Today is the last Friday of July, which means that it is System Administrator Appreciation Day. To all my friends and colleagues who spend days and nights and servers rooms or on shifts, who works remotely even when on holidays abroad, who’s mobile phones constantly buzz with SMS notifications of devices and services going up and down, who remember more numbers – IP addresses, network masks, port numbers, RFC numbers, etc – than any mathematician, who can troubleshoot a problem even with amount of alcohol in their blood lethal to mere mortals, to all of you guys – Happy SysAdmin Day! Have a good one!
