Like Google custom silicon, Amazon server operations are so large that with the slowdown of Moore's law, it started being worth it for them to develop custom in-house silicon to serve as a competitive advantage, not to be sold for external companies. Can you imagine the scale required to justify silicon development investment that is not sold externally!

This tutorial explains the very basics of how paging works, with focus on x86, although most high level concepts will also apply to other instruction set architectures, e.g. ARM.

The goals are to:

This is quite mind blowing. The laws of physics actually differentiate between particles and antiparticles moving in opposite directions!!!

Only the weak interaction however does it of the fundamental interactions.

Some historical remarks on Surely You're Joking, Mr. Feynman section "The 7 Percent Solution".

It gets worse of course with cP Violation.

How can you make a translation of the Bible and not put it in the public domain???? You tell me, you tell me.

With Falun Gong it's even more fun: the words of God Himself are will be copyrighted for a while after Li Hongzhi dies!!!

One of the most simple to state undecidable problems.

The reason that it is undecidable is that you can repeat each matrix any number of times, so there isn't a finite number of possibilities to check.

This is a good and simple first example of Lie algebra to look into.

Converts DNA to RNA.

This is a way to host a server that actually hide the IP of the server from the client, just like Tor hides the IP of the client from the server. Amazing tecnology!

This is why it enables hosting illegal things like the Silk Road: law enforcement is not able find where the server is hosted, and take it down or identify the owner.

I guess you also have to change the sign of the gravitational constant?

We looking at the definition the orthogonal group is the group of all matrices that preserve the dot product, we notice that the dot product is one example of positive definite symmetric bilinear form, which in turn can also be represented by a matrix as shown at: Section "Matrix representation of a symmetric bilinear form".

By looking at this more general point of view, we could ask ourselves what happens to the group if instead of the dot product we took a more general bilinear form, e.g.:The answers to those questions are given by the Sylvester's law of inertia at Section "All indefinite orthogonal groups of matrices of equal metric signature are isomorphic".
