Those would be called "antivirals"
No, we're calling them magnets now. The next step is finding out how magnets work.
Mom, you cannot know whether I've saw my brother doing bad things while I hid in the closet and watched... Otherwise he will know someone was watching from the closet and never again will forget to check if someone is in there.
It will wreck the whole tattling mission so I cannot ever spy on him again. There's just no other way except the ONE way I chose and since I think I'm so clever it's just better to never tell anyone what my brother is doing since my ability to spy on him from the closet is actually more important than whatever wrong I'm catching him doing.
I'm totally against spying on our own populace, especially by the NSA which wasn't created with that intent at all. There is some reason they are doing it and we need to find out why and who is having them do it. Are they acting outside of government authority or is someone in government endorsing what they're doing? If the NSA is acting on it's own abolishing the NSA might be a solution. If what they're doing is being authorized behind closed doors getting rid of them won't change a thing, it'll just put a different label on it.
What I was getting at is we don't know the full extent of what they are doing. We know they are spying on us. We don't know what they are doing for us, if anything. They probably can't tell us exactly what they are doing to benefit us because it would wreck that part of their mission. We're in a Catch-22. We need to find out whether they work for the people or someone else, and go from there.
The NSA is (theoretically) in a position where it cannot tell us what it has done for us. There may be all sorts of things the NSA has done to protect our nation. Publicly disclosing those actions could wreck their whole mission. We should consider, as IT professionals, that we're in a similar boat. We can't always tell the customer/client exactly what is going on, and even if we do tell them they're unlikely to fully understand. We definitely don't tell our customer's competitors what we are doing.
The real issue with the NSA is this: who is the customer?
Answer A: Yes, the judge can issue a warrant. On the other hand, the Irish guardia will tell any US police officer turning up at the house in Ireland with that warrant to piss off, possibly arresting them for trespassing or burglary. Answer B: In my opinion, yes. It will be difficult if the person has debtors in Ireland. Mortgage, unpaid bills etc. will likely come first.
I agree with A, it makes sense. B, not so much. I don't see how the US could seize real estate on foreign soil through a court action. They could try, but I don't see Ireland (in this example) agreeing to let them have the land.
Microsoft is headquartered and incorporated in the US and thus subject to US law. QED.
Consider this scenario: I am a US citizen who owns a house in Ireland. I commit a crime (in the US), say selling drugs. Can a US judge issue a warrant to search my house in Ireland? Let's say I am convicted. Part of the ruling is to have all of my property connected to the crime seized (by the US DOJ). Can they seize my house in Ireland?
A quick on-line search show a spindle of fifty 50GB Blu-Ray discs (2.5 TB) retails for about $100. A 4TB HDD costs about $140. So HDD is actually cheaper per byte of storage.
The initial hardware is cheaper with HDDs. Operational overhead might be entirely different. An HDD needs to be plugged in all the time (consuming power) while a Blu-Ray (or DVD for that matter) does not. Also, an infrequently accessed Blu-Ray, stored properly, is likely to have a much longer shelf-life than a drive that is always powered up, leading to lower overhead in the form of replacement/recovery costs.
