Programming is hard. To Ciro Santilli, it's almost masochistic.
What makes Ciro especially mad when programming is not the hard things.
It is the things that should be easy, but aren't, and which take up a lot of your programming time.
Especially when you are already a few levels of "simple problems" down from your original goal, and another one of them shows up.
This is basically the cause of Hofstadter's law.
But of course, it is because it is hard that it feels amazing when you achieve your goal.
Putting a complex and useful program together is like composing a symphony, or reaching the summit of a hard rock climbing proble.
A glitch is more precisely a software bug that is hard to reproduce. But it has also been used to mean a software bug that is not very serious.

After this is done, the final step is place and route.
They can be designed by third parties besides the semiconductor fabrication plants. E.g. Arm Ltd. markets its Artisan Standard Cell Libraries as mentioned e.g. at: web.archive.org/web/20211007050341/https://developer.arm.com/ip-products/physical-ip/logic This came from a 2004 acquisition: www.eetimes.com/arm-to-acquire-artisan-components-for-913-million/, obviously.
The standard cell library is typically composed of a bunch of versions of somewhat simple gates, e.g.:and so on.
- AND with 2 inputs
- AND with 3 inputs
- AND with 4 inputs
- OR with 2 inputs
- OR with 3 inputs
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:Those are then used in power, performance and area estimates.
- how long it takes for electrons to pass through
- how much heat it produces

Magic the gathering's banning of 7 cards due to "racism" (2020) by
Ciro Santilli 35 Updated 2025-03-28 +Created 1970-01-01
Official announcement: magic.wizards.com/en/articles/archive/news/depictions-racism-magic-2020-06-10
List of cards with images: www.hipstersofthecoast.com/2020/06/wizards-bans-7-cards-that-depict-racism-including-invoke-prejudice/
- Invoke prejudice: depicts the Ku Klux Klan. Card's title clearly criticizes them "prejudice".
- Stone-Throwing Devils: not sure about this one: boardgames.stackexchange.com/questions/54341/what-is-offensive-about-the-card-stone-throwing-devils
- Cleanse: it does not seem to have any reference to black people, image depicts fantastic animals. There are hundreds of cards that talk about black since it is one of the 5 colors of magic.
- Pradesh Gypsies: does not appear to suggest any bad things about gypsies, on the contrary
- Jihad: does not appear to suggest any bad things about Islam, on the contrary
- Imprison: depicts a black slave. Let's pretend it never happened.
- Crusade: pretend it never happened

Adds special relativity to the Schrödinger equation, and the following conclusions come basically as a direct consequence of this!
Experiments explained:
- spontaneous emission coefficients.
- fine structure, notably for example Dirac equation solution for the hydrogen atom
- antimatter
- particle creation and annihilation
Experiments not explained: those that quantum electrodynamics explains like:See also: Dirac equation vs quantum electrodynamics.
- Lamb shift
- TODO: quantization of the electromagnetic field as photons?
The Dirac equation is a set of 4 partial differential equations on 4 complex valued wave functions. The full explicit form in Planck units is shown e.g. in Video 1. "Quantum Mechanics 12a - Dirac Equation I by ViaScience (2015)" at youtu.be/OCuaBmAzqek?t=1010:Then as done at physics.stackexchange.com/questions/32422/qm-without-complex-numbers/557600#557600 from why are complex numbers used in the Schrodinger equation?, we could further split those equations up into a system of 8 equations on 8 real-valued functions.
