x86 Paging Tutorial / PSE Updated 2025-07-16
Page size extension.
Allows for pages to be 4M (or 2M if PAE is on) in length instead of 4K.
PSE is turned on and off via the PSE bit of cr4.
Marc Verdiell Updated 2025-09-11
Marc Verdiell is a French electrical engineer born in 1963 or 1964[ref] and best known for being the creator and host of the CuriousMarc YouTube channel where he does mind blowing repairs and reverse engineering of vintage computers and other electronic equipment.
Marc sold his company LightLogic, an optoelectronics company he founded, to Intel in April 2001. This was just after the dot-com crash, but Intel apparently still correctly believed that the networking and the Internet would continue to grow and was investing in the area. His associate Frank Shum sued claiming he should be credited for some of the inventions sold but lost and Marc got it all.[ref][ref][ref]. Marc was then almost immediately appointed an Intel fellow at the extremelly early age of 37, and then stayed for a few years at Intel until 2006 according to his LinkedIn.[ref][ref]
Figure 1. . Source. Location inferred from Marc's videos, but likely, he often frequents the place, and it looks a bit like that.
Marc's full name is actualy Jean-Marc Verdiell, but Ciro Santilli remembers there was one YouTube video where he mentions he gave up on "Jean" partly because anglophones would murder its pronounciation all the time.
Marc's PhD thesis is listed at: theses.fr/1990PA112048 and it is entitled:
Mise en phase de reseaux de lasers a semi-conducteur
which is translated into English as:
Phase locking of semiconductor laser arrays
but the full text is not available online.

youtu.be/ZgAreiFXhJk?t=253 lists some famous people who live there. It's like a micro heaven.
And a person who makes open educational content like Marc, truly deserves it.
Atherton managed to keep the entire place green and every house has a pool. Wikipedia comments web.archive.org/web/20220906010554/https://www.forbes.com/home-improvement/features/most-expensive-zip-codes-us/:
Atherton is known for its wealth; in 1990 and 2019, Atherton was ranked as having the highest per capita income among U.S. towns with a population between 2,500 and 9,999, and it is regularly ranked as the most expensive ZIP Code in the United States [(94027)]. The town has very restricting zoning, only permitting one single-family home per acre and no sidewalks. The inhabitants have strongly opposed proposals to permit more housing construction and Forbes confirms it for 2022: web.archive.org/web/20220906010554/https://www.forbes.com/home-improvement/features/most-expensive-zip-codes-us/, by far on top.
Marc has reached out to us and requested that some personal information be removed from this article, to which we complied.
x86 Paging Tutorial / TLB Updated 2025-07-16
The Translation Lookahead Buffer (TLB) is a cache for paging addresses.
Since it is a cache, it shares many of the design issues of the CPU cache, such as associativity level.
This section shall describe a simplified fully associative TLB with 4 single address entries. Note that like other caches, real TLBs are not usually fully associative.
Master's degree Updated 2025-07-16
In your normal 2020 broken educational system, it is the first time at which students get an official chance to learn something advanced, and possibly prepare to go venture into the PhD desert.

The good:
  • slick UI! But very hard to read characters, they're way too small.
  • attempts to show state diffs with a flash. But it goes by too fast, would be better if it were more permanent
  • Reverse debugging
The bad:
Matrix inverse Updated 2025-07-16
When it exists, which is not for all matrices, only invertible matrix, the inverse is denoted:
Yttrium barium copper oxide Updated 2025-07-16
Upside: superconducting above 92K, which is above the 77K of liquid nitrogen, and therefore much much cheaper to obtain and maintain than liquid helium.
Downside: it is brittle, so how do you make wires out of it? Still, can already be used in certain circuits, e.g. high temperature SQUID devices.
