Rather than locking the co-pilot out, just shoot/stab them, and keep the door locked.
Pilots have to go through the same security checks the passengers do. Or, at least, the pilots in the US do - I've seen them in the security checkpoints several times.
I live in Maryland in a home with a slab foundation and no crawl space or basement. We also have a very high water table, so high that I could probably go out right now with a shovel and hit water within a foot of the surface of the ground.
PairNIC, operated by Pair Networks. From their web site: "Launched in January 1996 and profitable since its second month of operation...". I have hosted with them for many years and their reliability is unbeatable. If you are a US-based business you can't escape US jurisdiction anyway and probably won't mind paying a couple of dollars more.
I've been using Pairnic for all of my domain names, no complaints, and the prices seem reasonable. I use them to host my website, too. At one point I switched to someone else (phpwebhosting.com, I don't know if they're still around) and complaints from my site's users about slow/unresponsive pages went from zero to daily, at least. I switched back to pair.com and those complaints dropped back to zero.
He rides outside when the weather is good and uses an indoor solution when the weather is bad, and you say he's likely a danger when he rides outside again? Seems a bit extreme. People don't forget balance and handling when they get outside again; neck problems kept me off bikes for ~10 years and I was able to hop right back into it without a problem.
If you're so tightly wound that a wiggle out of the guy next to you would cause a problem, then you're the danger, not him.
Gah. I had the opportunity to visit Vienna, Austria for work last summer, and my chip-and-signature cards were useless for automated kiosks. Fortunately a friend had lent me a few euros before I left, so I was able to use cash to purchase U-Bahn fare. Thanks to reading Slashdot comments, I knew about this problem and asked before the trip, and the credit card company (the one contracted by my employer for our company cards) said, "Errr, what? We have European travelers all the time and you're the first to ask!" But the same damn company has issued a chip-and-signature (personal) card to me for years. Yearrgghhh.
Austria seemed to be more of a cash operation anyway. I got a few odd looks when I pulled out the card, and I quickly realized cash was the norm. I even ran into one place that refused the card. The people were awesomely friendly, though. Austria is definitely on the list for a second visit.
I'm with you. I bought a Macbook Pro in 2009 because I didn't like any of the Linux laptop offerings, and I didn't want another Windows machine. I figured if I didn't like OS X, I could run Linux on it. Well, here we are over 5 years later and I'm still running OS X it. It's pretty nice, and I still have the command line.
That said, I'm typing this on a Kubuntu 14.04 desktop, and it's pretty nice too. My one gripe is that it seems a bit flaky compared to my prior Slackware installs - weird things like the login box showing on different monitors when I boot up (today it was on the second monitor; yesterday it was on the primary). Things like that make me a bit nervous, but aside from those it does work well. I just wish I'd installed Kubuntu 64 bit instead of 32 bit...I'm not sure why I did that, probably because of issues I had with libraries under Slackware64. (I still use Slackware on my server, but it's due for a software upgrade...I haven't decided what route to go with it.)
