Only 5 points out of 200 are about administrative law.
Pretty sure Leetcode subscription costs more than R$150 :) .
But yeah, if you are Donald Knuth, you can probably make more money in other places... if its important for you.

The main point is that it is a lot easier to trust something you can understand than some black-box machine certified by experts. Thus, eletronic voting systems are more vulnerable to trust attacks.
This creates another attack avenue, that is, you don't attack the results of the ballot, but you attack the entire system. You discredit the system because it is complicated, you use the limited understanding of the voter base to invalidate the results.
That is exactly what Bolsonaro did. He effectively proved the system is vulnerable to a trust attack... it does not matter if the system is safe from tampering if a significant part of the voters do not trust the system.
But this issue has become so politicized in Brazil that it has become impossible to discuss it reasonably. Pointing out any flaws in it is interpreted as an "attack to democracy".
The election system in Brazil is so perfect that you might go to jail if you say otherwise.
I would argue that an election system in which fraud is easy but obvious for everyone when present is more robust than a system in which fraud is hard but impossible for anyone to see.
That he did is the most revealing...
Calling this guy a hacker is a joke... as is this whole story. He is a scammer who got famous for accessing phone numbers of authorities using tricks he learned while scamming bank clients.
Shameless plug... Having worked on such systems, I recently wrote an article explaining real-time payment systems, some of which use real-time gross settlement:

Create a fit to purpose, simpler, protocol using a good interface specification language (OpenAPI or protocol buffers). Maybe borrow concepts and patterns from the ISO standard, but not adopt it. It will not deliver its promise of interoperability. It might actually make it harder to interoperate with other payment schemes.
Even the BCB itself has this ISO20022-xml to simpler-schema-in-json mapping layer.
If anyone from the FED is reading this I have this advice: don't use ISO20022! (I've been working on the brazilian instant payments project, known as PIX). It's an overly-complicated-try-to-solve-everything standard that promises interoperability but only delivers pain and misery. Since each country has its own standards for person and account identification, in dealing with these local realities, the ISO20022 adds quite a lot of complexity. But all this cost does not result in interoperability. In fact, each payment scheme end up with a localized version of the standard, incompatible with others. What could have been a clean API, ends up a mess.
Seems like all tools in this space (IT service management) are terrible. At work I have to use HP Service Manager. Just thinking of it makes me nervous. Made for bureaucreats by bureaucreats!
Looks a lot like what VoltDB has for stream processing. Will definitely make developing streaming apps a lot easier.
