I'm right handed but I use my mouse (more accurately track ball) with my left hand, but I have it set to right handed buttons. I was suffering mild RSI in the right wrist before I switched about 15 years ago. If I use somebody elses computer, I move the mouse to the left, and if they are lucky I might remember to move it back! Giving my left hand something to do has helped in other areas of daily life too.
I don't understand about right handed can openers - must be a 'Murican thing. I can't remember the last time that I used a tin opener. Here in Blighty, most tins are ring pull.
Uptime - less than a day. My only home machine is Linux and I shut the box down when I've finished with it. The Linux server that I use at work has been up 292 days - since the last area wide power failure.
Hostname - my home machine is localhost. My home machines have always been called localhost. At work, we're are mostly a Windows site. All of the machines are named after Star Trek characters, so my Linux server is Tuvoc. Almost all of the servers are virtualised; the physical boxes are named after starships. While it is fun to have silly names, it is confusing trying to remember which server you need to connect to. If I was in charge, we'd have sensible names like FS1, FS2 (file server), DC1, DC2 (domain controller), etc
Kernel - I recompile the kernel at home, taking out things that I don't need. At work I leave it alone.
