Matrix multiplication means picking up where multiple factors can be combined to produce a high score. It can analyze threat = capability x intent. I think this approach can be used as much by the individual trying to get a handle on reality (multiply news by what you know is possible) as by a massive organization (crunch data streams to find exploitable juicy bits).
If you think this way you will be paranoid. But, if you just want to imagine where things can go if they get even worse than they are now, say if unlimited resources are deployed by utterly immoral actors, it can be useful.
For example, without formal training I came up with the above threat equation. After typing the equation into Google, it turns out that it is correct and part of formal risk/threat assessment calculations. I figure that's because it is common sense.

Capability matrix:
Look. The entire data stream starting from the time a Kinect is plugged into electrical power can be automatically saved forever in a quiet data center.
XBox+Kinect is a very powerful listening device because of its smarts. It can download a program or search parameters and seek high-quality data, such as a conversation with a certain person's name in it, and filter it before sending it upstream. It can also compress a raw feed and gradually upload it over time.
So if anyone ever does something criminal or suggestive, like maybe your child has a party and someone does drugs in the living room, that data can be silently tagged and stored without any human's knowledge.
Any of your computers, or any computer ever in your vicinity throughout your daily life, or the lives of other people, can do the same thing. Just silently record at all times. There are too many ways it can be done in software. Free apps, buggy malware, browsers..
All phones, networked hardware, your car's On-Star navigation system and black box, can be additional channels.

Intent matrix:
Years later, if someone wants to find something on you they just make a mining query.
Queries can ultimately matrix multiply all locations x all channels x all individuals x all conversations files or positioning data.
Such as any conversation that mentions a target name or keyword ever held in front of anybody's XBox, personal laptop, tablet, wall phone, mobile phone, desk at work in any company. If you ignore any difficulty associated with processing/telecom/power/time capacity you will understand that rather than simply being "overheard" it is like you are leading your life by crawling over a jungle-gym moving from one data capture point to another. Your life over time and space, and those of all people with whom you interact, together become an immense transparent crystal object that can be observed at one's convenience from any angle.

Matrix Product: (exploitable output, or the threat)
Forget trying to end-run around the NSA, there is no point. But worry about other actors.
The U.S. data will be privately owned and controlled by other actors.
Any big company or country has a chance at subverting these streams and building their own global capacity.
A criminal organization could pressure a Verizon sysadmin.
The captured data does not have to go to court. It can be shown to someone else, or to you in order to embarrass you into tilting you towards a given course of action, for example if a target was shown video capturing an infidelity. The actor can dial in any degree of formality, truth or fairness.
Data that might have saved you (such as data proving innocence or entrapment) can be deleted, ignored, or modified in whatever private data center it is stored.
Parallel construction means all of this dark activity, a dark war against humanity, can be kept in the dark, but leveraged when some other expedient is selected.

Comments:
Once you or someone many steps removed who you don't even know has been targeted or an annotation has been made, all past and future activity can be scheduled for heightened investigation, including active installation of subversions to improve the data feed.
It can be quite impersonal, like a game of chess. And there is no way to remove your tag.
Since tangential conversations and proximity drive data insights, "living with sincerity and honesty" is irrelevant.
One might hope that automated moral agents (strong AI) might one day swing things in the other direction, but they don't exist except in science fiction at this point and anything close to it is owned by the organizations doing the collation.

No more disinfectant bio-barrier between Earth and the rest of the Galaxy.
Like turning off your firewall, what could possibly go wrong?

A psychopath brags.
Either that, or the facebook guys asked him to say it.

Someone had to say it ;)

Call me old school but transparent interception of https does not increase my feeling of safety. It breaks the net and any security I might imagine in a transaction. This technology will make it really easy for anyone to do what for example Microsoft does to Skype connections (which is why Skype isn't allowed in my company). It provides for any number of decryption points to be created between you and your bank or whatever. The doc suggests that it can be used for both anonymization and deep inspection, positing that both are "good". I think it depends on who the user is whether one is desirable or not. As for a company pushing corporate certificates down its users' throats without them knowing it, I think this is pretty dangerous. The Internet is such a pervasive part of life now that if not informed, a user has a reasonable expectation that his or her communications will not be intercepted and possibly reformulated. It is like an operator listening to your conversation and being able to interject words into the conversation that you both think the other has said. Perhaps some people who don't remember a time when there was no social media don't get it. However I think a company should trust its employees and not intercept communications leaving the company, it is despicable immoral and weakens human dignity.

If there are such overarching security issues like multimillion dollar contracts or secret plans that are worth alienating your workforce, then you should tell them and also install other demeaning but powerful security technology like biometrics, laser fields, strip searches, etc. The idea that some guys sat down to write this document and imagined that the "good" uses of this would not be massively overshadowed by the horrible uses of it is just so appalling it nauseated me to read it.

Yes this sort of thing is going on now. But no, I don't think it is a good direction for society, I am not talking about national security forces but about corporations who will find plenty of reasons to implement this, so that while the desired "responsibility to management" i.e. load balancing, security monitoring, whatever is performed, there will become much more generally available back doors into any available communication ready waiting for someone who thinks it might be neat to open the door. The technology works regardless of whether there is a court order or anyone responsible in the vicinity. You may think I am paranoid but I think it is one thing when the police need wiretapping to catch mobsters. (I doubt they would catch any terrorists that way but who knows.) But it is another thing when the campus police, the kindergarten babysitter, every tom dick and harry with a web/phone/video startup is going to see this as a fresh new playing field. If they want to outlaw ssl fine. But I don't want to be using ssl and not know if it really is working or not because my ISP or phone company or cable company feels a need to be a man in the middle. Must the net be infinitely porous? They just can't leave shiny toys alone.

So.. ham radio. Radio Club Venezolano. National Emergency Network. Satellite Dishes. ISS. Free hosting. Google... Facebook... friends.
There are probably a bunch of ways to get information in/out of Venezuela, at least in a one-way burst.
On the other hand http://www.yv5rcv.org/ tweets pane shows "Hmm, an empty timeline. That's wierd." Ouch.

Make seats face each other.
Then leave it up to human nature.

Could be simple seating.or more of a communal lounge.

That plus the rolling shutter illumination by strobe.

Probably it would be seen as a challenge I suppose.
Guarding someone like this would be a good use
Of DHS if not the Secret Service. I hope somebody is on the ball.

If he was immoral.
Which I doubt.
However I would not invite my mother to

... that x,y info in the grid is used to encode additional information, which allows you more info not *despite* but *because* only one photon hits the detector at a time. In other words this detector only works when only one photon can reach the detector at the same time, and the beam output will have to be weakened if the spacecraft is too close perhaps. So if the photon rate is 1 photon per millisecond the bit rate can be multiples of 1000 bps due to also having an extra couple of bits per photon saying which grid cell (pixel) the photon hit.

Key points
- They use superconducting nanowires to make a grid. I doubt anybody not in space is doing that
- Though I didn't catch it from the pdf, the article has a quote from NIST saying that x,y information inside this grid
- This allows an n x n pixel grid sensor to be built out of only 2n nanowires. A photon heats up a nanowire intersection to register a hit, then wait for it to cool down. p.s. cooling something down isn't that easy in space.
- Presumably you would have to beam a repeating pattern (or hologram?) covering a broad area, and the pattern resolution would be adjusted as distance to target spacecraft changes over time.
