Ciro Santilli 40 Updated 2025-07-16And above all, you can always learn software engineering later on for free, because the programming community is so much more open than any other so far, notably e.g. with Stack Overflow and GitHub, see also: Section "Ciro Santilli's Open Source Enlightenment". Ciro Santilli is trying to change that with OurBigBook.com, but don't hold your breath. But it is increasingly hard to understand why there isn't an university that forces teachers to publish all their notes and lecture videos (which should be mandatorily recorded) with a Creative Commons License, and then let anyone take whichever exams they want for a small fee or for free.
Actually, there is a good chance you will learn to program, like it or not, because chances are that you won't be able to find as decent a job doing anything else.
But there is one thing you cannot learn for free: laboratory work. Laboratory work is just too expensive to carry out outside of an institution.
Basically, if you don't do laboratory work in undergrad, you will very likely never be able to do so in your entire life.
Because laboratories are so rare and expensive, it is laboratories that put you in the best most unfair position at creating world changing deep tech startups, which is why when in doubt, choose the course that has the most experimental work. Yes, you won't be able to achieve those insanely concentrated equities of the early-Internet, as you will need more venture capital to run your company, but those days are over now, deal with it.
The Eighth Day of Creation has a related quote:
In a conversation a few weeks earlier at the faculty club of the Massachusetts Institute of Technology, a couple of biologists had speculated whether Pauling, whose recent popular book on the benefits to health and sanity of massive doses of vitamin C was stacked in display near the entrance of the M.I.T. bookstore, was showing signs of what one of the men called "old scientist's disease" - which they defined as what happens to great men when they grow beyond the psychological reach of the salutary system by which scientists blow the whistle on one another's mistakes.

Instrumentation basically means adding loggers/print statements to certain points of interest of your hardware/software.
The downside is that if the instrumentation does not provide you the data you need to debug, there's not much you can do, you will need to modify it, i.e. you don't get full visibility from instrumention.
This is unlike emulation that provides full observability.
Within the The Holy Trinity of popular Brazilian music, Caetano has the most New Age religious feel to him. He is also perhaps the most varied of the trinity however, also covering heavier topics at times.

Within the The Holy Trinity of popular Brazilian music, Chico tends to approach the more down to Earth and heavy topics.

Gilberto is definitely the most psychedelic/tribal one of the The Holy Trinity of popular Brazilian music, though he also has a boyish quality to his soul.
He is also perhaps the one that impresses Ciro Santilli the most, at times he can't help but feel:
OMG how the hell did he come up with that?!

Ciro Santilli was a bit young to understand the songs at the time, but the older boys were singing them, and he sang along. So maybe there is a nostalgia factor in play.
But it can't be just that. They are just too funny and brutal, even when Ciro re-listens to it as of 2020.
Many Brazilian religious cranks in were really happy when their plane crashed and killed all of them in 1996.

Best songs:
- Pelados Em Santos (1995). Not too amazing, they only try to be funny by making fun of the North-Eastern accent of Brazil, which is considered somewhat funny in São Paulo, and they fail at being funny.But it talks about Santos, São Paulo, Brazil, Ciro's idolized city, so let's hear it. They didn't live in Santos apparently, but being from São Paulo City, they would have been familiar with that popular local beach location.

Basic analogue phones connected to the public exchange use two wires mainly arranged as a twisted pair to reduce noise. The voice signal is differential (the voltage in one wire equal and opposite to the other) biased above ground by 48V. Using a twisted pair reduces induced noise because the noise signal will induce an equal voltage in each wire and because the signal is transmitted as the difference the effect of the induced noise will be dramatically reduced.
