Open source driver/hardware interface specification??? E.g. on Ubuntu, a large part of the nastiest UI breaking bugs Ciro Santilli encountered over the years have been GPU related. Do you think that is a coincidence??? E.g. ubuntu 21.10 does not wake up from suspend.

- youtu.be/TRZqE6H-dww?t=694 they bet on Direct3D
- youtu.be/TRZqE6H-dww?t=749 they wrote their own drivers. At the time, most drivers were written by the computer manufacturers. That's insane!

Source. This is the possibly infinite dimensional version of a Hermitian matrix, since linear operators are the possibly infinite dimensional version of matrices.
There's a catch though: now we don't have explicit matrix indices here however in general, the generalized definition is shown at: en.wikipedia.org/w/index.php?title=Hermitian_adjoint&oldid=1032475701#Definition_for_bounded_operators_between_Hilbert_spaces
One is reminded of Nick Leeson.
One things must be said: the root cause of all of this is the replication crisis.
This is why he managed to go on for so long.
People felt it was normal to have to try for one or two years to replicate a paper.
The man who almost faked his way to a Nobel Prize by BobbyBroccoli (2021)
Source. Playlist: www.youtube.com/watch?v=nfDoml-Db64&list=PLAB-wWbHL7Vsfl4PoQpNsGp61xaDDiZmh&index=1This theorem roughly states that states that for every quantum algorithm, once we reach a certain level of physical error rate small enough (where small enough is algorithm dependant), then we can perfectly error correct.
This algorithm provides the conceptual division between noisy intermediate-scale quantum era and post-NISQ.
Lagrangian mechanics lectures by Michel van Biezen (2017) Updated 2025-01-03 +Created 1970-01-01
Original playlist name: "PHYSICS 68 ADVANCED MECHANICS: LAGRANGIAN MECHANICS"
Author: Michel van Biezen.
High school classical mechanics material, no mention of the key continuous symmetry part.
But does have a few classic pendulum/pulley/spring worked out examples that would be really wise to get under your belt first.
The key difference from Lagrangian mechanics is that the Hamiltonian approach groups variables into pairs of coordinates called the phase space coordinates:This leads to having two times more unknown functions than in the Lagrangian. However, it also leads to a system of partial differential equations with only first order derivatives, which is nicer. Notably, it can be more clearly seen in phase space.
- generalized coordinates, generally positions or angles
- their corresponding conjugate momenta, generally velocities, or angular velocities
Heinrich Hertz's main initial experiment used a spark-gap transmitter. It is not something that transmits recorded sounds like voice: it only transmits noisy beeps. And as such was used for wireless telegraphy.

- a more powerful home-made transformer
Hertz and Radio waves Explained by PhysicsHigh (2016)
Source. Simple schematics showing the basics of the experiments. No choice of components rationale.As of 2019, the Standard Model and general relativity are incompatible. Once those are unified, we will have one equation to describe the entirety of physics.
There are also however also unsolved problems in electroweak interaction + strong interaction, which if achieved is referred to as a Grand Unified Theory. Reaching a GUT is considered a sensible intermediate step before TOE.
The current state of Physics has been the result of several previous unifications as shown at: en.wikipedia.org/wiki/Theory_of_everything#Conventional_sequence_of_theories so it is expected that this last missing unification is likely to happen one day, potentially conditional on humanity having enough energy to observe new phenomena.
Now that's sweet:With the visual tileset out of box.
This is the actual main function of university for many people as of the 2020s. And it fulfills it quite well. A breeding ground.
In a closely related sense, university is simply a symbol of personal status. Not a place where you go to learn. And especially in the Anglophone world of fancy colleges, university also doubles down as a form of long term luxury hotel. Even if it ends up meaning debt.
There's nothing wrong with sexual selection. This type of natural eugenics is an important part of humankind. It is however just sad that any type of learning falls so much behind. A close second would be fine. But as it stands, it is just too far off.

Other notable people that are likely also awesome but Ciro has less familiarity with their contributions:
- Dwayne Richard Hipp from SQLite
- Daniel Stenberg from cURL
- Michael Niedermayer also from FFmpeg. ikaruga.co.uk/~snacky/mn.html highlights his brutal directness and efficiency, and sometimes sense of humour

There are unlisted articles, also show them or only show them.
