Tor works by setting up multiple layers of vpn's between nodes in laters in a way that traffic is passed between nodes without them knowing the contents.
You want to connect to c so you set up a vpn between a and b then b and c and use both of those vpn to set up another vpn between a and c.

That is the a kind of traffic analysis that can be done if you are a government and can monitor enough nodes.
While any one node may not know what is being transmitted and to where you could see that a series of packets came through in to one node and a few seconds later a similar amount of data was transmitter do another node.
If you are unlucky one of these bad nodes could also be an entrance or exit node and they would see what you are sending.

There has also been research that showed that if you monitor a voip call transmitted through a vpn you can guess what they are saying by the traffic spikes as words are spoken.

This is something different.
Take the linux kernel, split it into modules such as tcp/ip stack etc.
Now you can create a binary that includes the part of the os that you need that you can include with your binary.
You then link the kernel and your application so you have one binary with the bits of the os you need as well as your program and nothing else.
No init system, no other processes just the os.
You can then run this inside xen as the target so you don't need the hardware support.

Webrtc is a standard that has been in the browser for the last year or more.
What the button does is open a web page that calls the standard api's.
Adding this button does not bloat the browser that much because the underlying api is already there.

While that makes sense that was the answer ~30 years ago and is completely wrong.

If you calculate the calories you eat and compare it to your usage you only absorb a fraction of what you digest (~1/4 from memory). Reducing the amount of calories in your diet does not reduce the total absorbed as there is a lot of surplus energy in what you eat.

What seems to be useful is looking at what in your food you absorb and eating high fat may actually be good for you as you don't absorb it.
Eating low fat foods is bad as they replace fat with sugar and sugar is what your body turns to fat.

While that sounds good there are people that still round up the opposition in to one area and shoot them.

It is unlikely to be a problem to you or me but encouraging a system that makes it possible is a bad thing for the world.

The problem with that argument is that it only works in the USA, the rest of the world is screwed.

Related to this is the idea someone proxying captcha.

Instead of providing your own captcha solve google's captcha. When someone creates an on your site connect to google and try and create an account, you then forward the google captcha to the user.

One of them is a real scientist with a PHD.

Just one minor point we do allow 18+ games in Australia since the start of the year but there are still some restrictions.
When southpark's stick of truth was released we had a few things cut (anal probe mini game) but this was the same in a few countries.

I believe the dns-sec root keys are an example of a key in multiple parts.

The master key can be reconstructed by combining 7 keys together.
There are 14 people that have part of the key and I believe any 7 people can be used to recreate the whole key again.

With my pebble watch and a custom watch face I can tell you that the current swatch time is @150.

As bitcoin uses public / private key cryptography you could have clients only have the public key until you need the private key.
So the client would be able to see that someone has sent them bitcoin but not be able to use them as they do not have the key allowing a store to validate that someone has sent in the coins.

Paper wallets is one implementation of this idea, where there is a piece of paper with 2 qr codes with your public and private keys.
Give everyone your public key but when you need to send the coins somewhere you need to scan the qr code to import the key.
You could probably come up with a system requiring you to assemble the private key from several parts.

Obfuscation provides no security, it just looks like it does.
If the operating system needs to perform a series of steps to turn the encrypted password back into plain text so can an attacker.
