People are becoming addicted to prescription painkillers. They cannot just buy these products. Therefore they (or others) have to rob them. Men worry about "erectile disfunction" because of advertising. Robbers steal the same products that are advertised for this. Guns are widely available in the US. Guns are used to commit these robberies. Police shoot the suspect because he's carrying a gun.
The decoy pill bottle is just a symptom in all this.
This just means that booksellers are getting a hidden subsidy from French readers. Sure, you can make anything a success if you have the government enforcing your rent-seeking behaviour. But I wonder if the customers would be happy if it was laid out to them that this policy directly costs them a hidden X euros a year.
PulseAudio sucks, but systemd is reasonable stuff. It's like upstart (but done right) combined with inetd.
Unlike what another reply says, systemd does not require changes to daemons.
The two times I've bought houses, you bet I read every single word of every document, even the ones I didn't have to sign. Not doing so is just laziness and stupidity when you're making such an enormous purchase.
Safe fast languages:
SML, OCaml and some of the other functional languages. Usually within a few % of the speed of C, and far safer.
However you're absolutely right in your list, and it's very unfortunate that programmers have forgotten or never even knew about these things.
If you track down The Secret Life of Machines Series 1, The Television Set you can see this sort of set (perhaps even this very set) being demonstrated.
AIUI you wouldn't want to turn this on for very long, or at least not without a fire extinguisher handy. Some of the electronics (capacitors I think?) are made of paper and after all this time have dried out and are prone to catching fire.
My experience is in data centres that I've seen and visited, not in power supplies. Show us a significant data centre that promises to run the whole thing from diesel generators.
From my experience, I've seen data centres that have two supposedly redundant power supplies (usually this just means two paths into the data centre from the same supplier).
It seems unlikely/improbable to me that a data centre could be supplied from local diesel generators. The power consumption is just far too great. So your answer is "not safe at all".
You can change the underlying disks - we do this for virt-v2v.
RAID/md is not used much by virtual machines (it's done on the host instead) so I can't comment on what problem you had.
Please don't use
You cannot change the underlying disks (eg. to do migration or V2V) without the guest becoming unbootable.
Use filesystem UUIDs instead. These survive all sorts of migrations and conversions intact, and are even useful in the non-virtual case -- eg. if you swap SATA disks around.
Crazee Edeee, his prices are INSANE!!!
