Very clever. I approve.
I appear to be in the market for a new KVM as my current one has all but stopped working. Any recommendations? Minimum 4 outputs. *Must* do VGA. My current one has mini-DIN for keyboard and mouse, which has sort of worked some of the time with USB-PS2 converters. I could probably go for a full USB only one, but I'd need to get new cables.

The launch window is small because ISS has to be essentially lined up in orbit in a tight tolerance (called the phase angle) to rendezvous this quickly. Usually the Soyuz plays "catch up" over 2 days by flying lower (and faster) than ISS. You can control the closing rate between the vehicles by altering the altitude difference between them, which allows you to make up differences in the orbits between the vehicles. Those differences are usually just fallouts of other things, like having uncertainty in launch dates, getting the altitude just right for other vehicles (there is about a rendezvous a month at ISS), etc. It's not because Soyuz is slow, it's because spreading the rendezvous over 2 days gives you some targeting flexibility.
You have less margin to work with when you are trying to get there in 4 orbits instead of 34 orbits. Hitting that target with both ISS and Soyuz is hard but it's more about ground targeting than performance of the launch vehicle. The launch vehicle didn't give any extra oomph to get there faster, the ground essentially had the vehicle phasing in a tight tolerance at launch. They also sped up some of the tracking that was being done and turning that around into updated burns for the next orbit instead of coasting to a set of burns the next day, which was a bunch of work for the ground in a short period of time.
The Russians that devised this actually published it - it's an interesting read if you have access to the journal or want to spend $32:
Crazy war stories, indeed.
My decision to rip all of my audio losslessly to FLAC has been vindicated. I rip to Vorbis as well, but I always thought it was worth having the lossless originals around too. That way, if a new codec arrived on the scene at a later date, I could rerip to that without any further loss of quality. That codec is now here. Hello, Opus!
I have a backup server at a second independent data center
As do I
Some people think I'm paranoid. I wouldn't say so. It's just that I pay more attention to the potential worst case outcome that some. So when it comes to storage, I have a mirrored RAID array in my home server. The contents are backed up to a separate disk in the same machine. I also have an offsite backup in a datacentre.
I'll ask my electrician for a full size rack on wheels, but if he can't get one, the wall mount it is
Unless you need the full 42u, I'd definitely go for something smaller. A half-ish rack on wheels should be more than adequate, will be less imposing, and they're relatively cheap, too. We have a couple in the office at work because the few machines that aren't in one of the data centres don't need a full height permanent rack. I can't believe there isn't a suitable supplier in Luxembourg, given the number of financial institutions there. But if not, there should be plenty in Germany, right?
Yes. I've been saying this for a long time. Email is pretty much the definition of a perfect store and forward messaging system. Plus, I completely agree with him about the omission from the spec.
