The problem with a single-level paging scheme is that it would take up too much RAM: 4G / 4K = 1M entries per process.

If each entry is 4 bytes long, that would make 4M per process, which is too much even for a desktop computer: ps -A | wc -l says that I am running 244 processes right now, so that would take around 1GB of my RAM!

For this reason, x86 developers decided to use a multi-level scheme that reduces RAM usage.

The downside of this system is that is has a slightly higher access time, as we need to access RAM more times for each translation.

The Quantum Story by Jim Baggott (2011) page 2 mentions how newton's support for the corpuscular theory of light led it to be held for a very long time, even when evidence of the wave theory of light was becoming overwhelming.

Looks cool. That's what 1k USD gets you.

This is really cool. Ciro Santilli would be tempted to participate, but his wife is not a fan, in part due to the loss of privacy of children. Maybe she is right...

Someone should implement a version of that where you can upload your privately sequenced genome and get analytics for free.

Exciting... sometimes cruel. But too exciting not to do:

They split up from the rest of the mammals after the monotremes.

Every other mammal has a placenta.

This baby in pouch thing just feels like a pre-placenta stage.
