Minimal example: github.com/cirosantilli/x86-bare-metal-examples/blob/5c672f73884a487414b3e21bd9e579c67cd77621/paging.S

Like everything else in programming, the only way to really understand this is to play with minimal examples.

What makes this a "hard" subject is that the minimal example is large because you need to make your own small OS.

This is an example of how paging operates on a _simplified_ version of a x86 architecture to implement a virtual memory space with a 20 | 12 address split (4 KiB page size).

If either PAE and PSE are active, different paging level schemes are used:

Two level address translation to make OS emulation more efficient.

Your profile picture, name and status are public by default as of 2022!!! OMG!!!

This means that all secret services in the world have alrady scraped this information for everyone that uses WhatsApp!!!

They just have to go incrementally through the list of all phone numbers... 001 0000 0000, 001 0000 0001, 001 0000 0002, etc. and then you can deduce who has which phone number.

OMG... it is analogous to the Facebook profile face dump.

Sure, it is forbidden in theory: faq.whatsapp.com/general/security-and-privacy/about-harvesting-personal-information/.

Course actually means "degree", not just one specific "course":

The course outline is given in a "handbook", a one or more PDF files that contain what people will learn and other practicalities. There is a full list of handbooks at: www.ox.ac.uk/students/academic/guidance/undergraduate/handbooks, but many of them are closed. The system is so closed that even the fucking course list is closed, e.g. all links at: www2.physics.ox.ac.uk/students/undergraduates are closed. Insane.

The second one of the University of California after UC Berkeley.

The Twelve Apostles were actually officially appointed by Jesus amongst his followers. It was not simply that they were the first followers. It was official rank.

Trapped ion people acknowledge that they can't put a million qubits in on chip (TODO why) so they are already thinking of ways to entangle separate chips. Thinking is maybe the key word here. One of the propoesd approaches inolves optical links. Universal Quantum for example explicitly rejects that idea in favor of electric field link modularity.

The major problem with SVG is text computer fonts. If you make an image with text that depends on one computer font and it is not present in the viewer's machine, it will use some other font, which may overlap with other elements of the image. Some libraries Matplotlib solve this by writing characters as curves, but this produces large files and unsearchable text. The inability of different computer platforms to standardize fonts that must always be present is a major issue.

Decompilation project: github.com/MitchellSternke/SuperMarioBros-C. That project does not produce the ROM however, it reimplements an emulator + game in a single binary.

Not to be confused with Subtitle Edit.

As of 0.54.0 this feels featureful, but extremely buggy or lacking UI obvious enhancements that would be simple to implement, and offer huge value:

It is hard to understand how that project reached this weird featureful but crappy state. Feels like they just gave push permission to a bunch of random people.
