If we look at jet aircraft, wear depends on the airframe and the engines, and the airframe seems to be the number of pressurize/depressurize cycles as well as the running hours. Engines get swapped out routinely but when the airframe has enough stress it's time to retire the aircraft lest it suffer catastrophic failure. Rockets are different in scale (much greater stresses) but we can expect the failure points due to age to be those two, with the addition of one main rocket-specific failure point: cryogenic tanks.
How long each will be reliable can be established using ground-based environmental testing. Nobody has the numbers for Falcon 9R yet.
Weight vs. reusable life will become a design decision in rocket design.
Volume shadow copy is a feature of Samba, not FreeNAS specifically. So, yes, you can use it with NAS4Free.
Meh, I played around with FreeNAS for a while. I originally thought it was neat, but I kept having problems with it and eventually realized that it was easier to just set everything up myself. The GUI didn't offer that much in the way of ease of use. A short list of my observations.
1) FreeNAS makes it dead easy to set up ZFS...but ZFS is actually pretty easy to setup on its own. Easier than RAID/LVM by far. So no huge gain there, in my opinion.
2) FreeNAS makes it so you don't really have to learn the ins and outs of FreeBSD, but zfsonlinux is fairly mature and works well, so not a big deal for me.
3) This may be my linux bias showing, but FreeNAS is limited by the capabilities of FreeBSD. Hardware support is the biggest one (controllers, nics, etc). For example, plenty of Dell hardware won't work optimally. Also, what the fuck did they do the PAM? Lots of functionality missing (kerberos password changing, mkhomedir, etc). The version of SCP seems to come from a stone age that doesn't know about directory recursion. Just lots of little things that really annoyed me. No NFSv4 support. Seriously, this is like 10 yrs old now, and you still can't authenticate NFS users over Kerberos if you are using FreeNAS. Maybe it is fixed in this version, but not in 9.2.
4) Some aspects of the UI were nice (ex: being able to easily to see appropriate ZFS flags) and other not so nice (ex: the snapshot interface). Yes, FreeNAS supports the ability to replicate ZFS, but this requires a cumbersome setup that even involves saving your ssh private key into the UI (maybe they have changed this since then). It's easier to just set this up in a cron job on your own, in my opinion.
5) FreeNAS makes some things very easy, but if you need to do anything differently, it's a pain to work around the UI. The settings are saved in a special database that writes config files on the fly, so you have to know what to edit to make a change. I spent a lot of time making FreeNAS talk to our domain controller and enumerate groups correctly, because the UI had a generic way that didn't work with our schema and there was no way to just change the necessary settings.
Bottom line: if you want to get a quick NAS running to use as a media server, FreeNAS works pretty well. But if you have special hardware or integration needs, you can probably achieve everything you need much easier by just configuring everything by hand.
I think everyone is trading anecdotal evidence, but in well over a decade of living in Europe and never bothering to make an EHIC, but sometimes falling ill when travelling in another EU country than my own, I have never been charged, and other travellers I know report that they have not been charged more often than not.
You would expect to be charged at an airport clinic, as this is a place that gets a lot of foreigners, so their billing is streamlined for it. Your treatment in a small town hospital that rarely sees foreigners would likely have been quite different.
I'm WHAT? I'm arguing for a change?
Is claiming that a status quo is unjust not wishing for change?
Your use of the term "currently" when referring to the ex-pats implies a short-term nature of the ex-pat status, which also makes them less than location-independent.
I don't see where you get that from. Merriam-Webster defines "currently" as simply " happening or existing now" with no connotation that it's a temporary thing. Many US citizens abroad have left the US for good (or have never lived there, but simply received US citizenship through ius sanguinis), and they now, as they vote, are living somewhere else.
With regard to the American Revolution, the colonists who pushed for a break with England supposedly wanted no taxation without representation. US citizens abroad must file US taxes, and denying them the right to vote would mean being taxed without representation.
