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.
Super Mario Bros. reverse engineering by Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01
Commented and labelled disassembly: gist.github.com/1wErt3r/4048722
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:
- fundamental not defined out of box, e.g. Tiny forward/backwards. You can define them yourself, but they should be provided.
- github.com/SubtitleEdit/subtitleedit/issues/4976 can't export SubRip?
- can't interact with video on waveform?
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.

A quick look at PostgreSQL's compliance notes: www.postgresql.org/docs/13/features.html shows the complete utter mess that this standard is. Multiple compliance levels that no one fully implements and optional features everywhere.

Solutions of the Schrodinger equation for two electrons by Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01
TODO. Can't find it easily. Anyone?
This is closely linked to the Pauli exclusion principle.
What does a particle even mean, right? Especially in quantum field theory, where two electrons are just vibrations of a single electron field.
Another issue is that if we consider magnetism, things only make sense if we add special relativity, since Maxwell's equations require special relativity, so a non approximate solution for this will necessarily require full quantum electrodynamics.
As mentioned at lecture 1 youtube.com/watch?video=H3AFzbrqH68&t=555, relativistic quantum mechanical theories like the Dirac equation and Klein-Gordon equation make no sense for a "single particle": they must imply that particles can pop in out of existence.

Why it is hard to simulate quantum systems? by Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01
This is basically how quantum computing was first theorized by Richard Feynman: quantum computers as experiments that are hard to predict outcomes.
TODO answer that: quantumcomputing.stackexchange.com/questions/5005/why-it-is-hard-to-simulate-a-quantum-device-by-a-classical-devices. A good answer would be with a more physical example of quantum entanglement, e.g. on a photonic quantum computer.

She's kind of lying on top of the horse's back, and you can't see much, just some tastefully light erotica. It's not like she's fucking the horse or anything.
Journals must require source code and data sets to publish by Ciro Santilli 34 Updated 2024-12-15 +Created 1970-01-01
It is understandable that you might not be able to reproduce a paper that does a natural science experiment, given that physics is brutal.
But for papers that have either source code or data sets, academic journals must require that those be made available, or refuse to publish.
Any document without such obvious reproducibility elements is a white paper, not a proper peer reviewed paper.
