West Bank Updated +Created
The Israeli occupation is obscene.
The only reason the UN doesn't do anything is that other countries can't be bothered to send people to fight Israel and die there.
And the outcome of this is fundamentalism and indirect deaths elsewhere.

Standard cell library Updated +Created
Basically what register transfer level compiles to in order to achieve a real chip implementation.
After this is done, the final step is place and route.
The standard cell library is typically composed of a bunch of versions of somewhat simple gates, e.g.:
  • AND with 2 inputs
  • AND with 3 inputs
  • AND with 4 inputs
  • OR with 2 inputs
  • OR with 3 inputs
and so on.
Each of those gates has to be designed by hand as a 3D structure that can be produced in a given fab.
Simulations are then carried out, and the electric properties of those structures are characterized in a standard way as a bunch of tables of numbers that specify things like:
  • how long it takes for electrons to pass through
  • how much heat it produces
Those are then used in power, performance and area estimates.
Stationary action principle Updated +Created
As mentioned on the Wikipedia page en.wikipedia.org/w/index.php?title=Stationary_Action_Principle&oldid=1020413171, "principle of least action" is not accurate since it could not necessarily be a minima, we could just be in a saddle-point.

As for his lost password and inaccessible Bitcoin, Mr. Thomas has put the IronKey in a secure facility - he won’t say where - in case cryptographers come up with new ways of cracking complex passwords. Keeping it far away helps him try not to think about it, he said.
“I would just lay in bed and think about it," Mr. Thomas said.

Stern-Gerlach experiment Updated +Created
Originally done with (neutral) silver atoms in 1921, but even clearer theoretically was the hydrogen reproduction in 1927 by T. E. Phipps and J. B. Taylor.

x86 Paging Tutorial / Linux source tree Updated +Created
In v4.2, look under arch/x86/:
  • include/asm/pgtable*
  • include/asm/page*
  • mm/pgtable*
  • mm/page*
There seems to be no structs defined to represent the pages, only macros: include/asm/page_types.h is specially interesting. Excerpt:
#define _PAGE_BIT_PRESENT   0   /* is present */
#define _PAGE_BIT_RW        1   /* writeable */
#define _PAGE_BIT_USER      2   /* userspace addressable */
#define _PAGE_BIT_PWT       3   /* page write through */
arch/x86/include/uapi/asm/processor-flags.h defines CR0, and in particular the PG bit position:
#define X86_CR0_PG_BIT      31 /* Paging */
