Once we had the amplified 16S DNA, we were almost ready to start sequencing!

A computer model that is as powerful as the most powerful computer model we have: Turing machine!

Ciro Santilli can accept closed source on server products more easily than offline, because the servers have to be paid for somehow (by stealing your private data).

A polynomial of degree 1, i.e. of form $ax+b$.

As of 2020, no one knows how to build the major desktop distros fully from source into the ISO, and especially so in a reproducible build way. Everything is done in build servers somewhere with complicated layers of prebuilds. It's crap.

The first quantum mechanics theories developed.

Their most popular formulation has been the Schrödinger equation.

Physical address extension.

With 32 bits, only 4GB RAM can be addressed.

This started becoming a limitation for large servers, so Intel introduced the PAE mechanism to Pentium Pro.

To relieve the problem, Intel added 4 new address lines, so that 64GB could be addressed.

Page table structure is also altered if PAE is on. The exact way in which it is altered depends on weather PSE is on or off.

PAE is turned on and off via the PAE bit of cr4.

Even if the total addressable memory is 64GB, individual process are still only able to use up to 4GB. The OS can however put different processes on different 4GB chunks.

Why are pages 4 KiB anyways?

There is a trade-off between memory wasted in:

This can be seen with the extreme cases:

x86 designers have found that 4 KiB pages are a good middle ground.
