Helping the NSA find baby-jesus

This is for July 1st

June 26th, 2013

I'm putting this up now so that I don't forget later...

Happy Canada Day! Even though I'm absent from Canada I thought I'd say peace! Eh!?


How everyone's Internet should be like

June 26th, 2013

When I speak to people about how the Internet should be like I liken it to a spider web.

The spider doesn't create one link but several, as means of redundancy and stability. So when humans build an Internet usually in its first phases it looks like this:

        o o o o o o o o o o o o o o o 
        | | | | | | | | | | | | | | |
In this ASCII drawing you have a trunk and end-users (drawn as "o"). There is a (BR) (bad router) that the government spies sit at and listen to everyone. We have to admit it's like this because it is. We are being spied upon and are making it very easy. But it doesn't have to be like that. We can make changes...we can work out a spider web between neighbouring houses (end-users). It would look like this:

As you can see everyone has 2 or more gateways that they use. This is what's called a "mesh" (and the purple links are its links). The model is just a small neighbourhood but it should be linked with an entire city like this. The light blue is gateways to the Internet. The Internet past these gateways should look like 1 house in this picture as well. The trick is to send packets in any random direction and the packet will seek its destination any random way. This requires new routing protocols that make this possible. It requires investments by neighbours to create the links, and government approval. It makes spying on the communications of any single person very difficult and that is its intent. Just we gotta realise this some day and do it.


UFO sighted

June 25th, 2013

I took this picture of an UFO outside my window. It's possibly a weather balloon judging how it rose into the air. But the shape is somewhat odd.

You can click on the jpg to make it bigger I think. I scaled it 50%.


The Key Satellites

June 25th, 2013

We should encrypt our private conversations, how do we do that? I believe quantum encrypted laser links to polar orbiting satellites in low earth orbit are a good thing. These then communicate to higher geostationary satellites and vice versa. Whenever the geostationary satellites talk back to the polar satellites they wait until the beam is at tangent with the curvature of the earth so that the beam would never hit earth. The transmission payload would be only AES or similar crypto keys which are then used symmetrically without assymetric key exchange. I think this is worthwhile for states such as Germany and german embassies world wide. A VPN to your embassy would be cool too if you're abroad somewhere in order to make use of this crypto. This is all a response to the TAT-14 spying.


Got a new book

June 25th, 2013

I got this new book called "Absolute OpenBSD: UNIX for the practical paranoid" by Michael W. Lucas.


What government should do

June 23th, 2013

Governments outside of the so-called five eyes nations are outraged over the prism and tempora sniffing programmes. However you can't change a dumb user to not encrypt, in fact it's hard to encrypt for most people. I'm afraid there is no easy way, but perhaps the fabric of the Internet can be re-woven in such a way that prism and tempora have a harder time gaining data. Let's pretend government said "we want you to use P2P protocols" and really encourages it. With P2P a lot of data is moved and it goes in all directions. I believe it would be a good initiative when you can't use encryption. Other than that perhaps develop Operating Systems and crypto systems outside of the USA and Britain in order to offset the current status quo. Also the structure of the Internet shouldn't just be a grand trunk with subnets, it should be a mesh and a mesh of hubs. Think about this last line a bit.


Sunny Solstice

June 21st, 2013

Ever wonder where the sun is (constellation) when it's northern solstice?

Look how Jupiter is occulted by the sun. Not sure if it's the right term but does that mean it's at opposition? I thought this fact was special. Jupiter behind sun at solstice, both in the constellation of Taurus almost in Gemini. Can you feel their gravity pulling on you?


The moon last night

June 20th, 2013

From my balcony, but I was shaking the camera unfortunately...


Some video about Wildcarddnsd

June 18th, 2013

This was really hard to do for me, considering there was hardly a script.
