You must be good at Math

Serious question; how does Calculus apply to programming? I’ve never understood.
Graphics programming is the most obvious one and it uses it plenty, but really any application that can be modeled as a series of discrete changes will mostly likely be using calculus.
Time series data is the most common form of this, where derivatives are the rate of change from one time step to the next and integrals are summing the changes across a range of time.
But it can even be more abstract than that. For example, there's a recent-ish paper on applying signal processing techniques (which use calculus themselves, btw) to databases for the purposes of achieving efficient incremental view maintenance: https://arxiv.org/abs/2203.16684
The idea is that a database is a sequence of transactions that apply a set of changes to said database. Integrating gets you the current state of the database by applying all of the changes.

If a C- is enough to pass Analysis of Algorithms, then a Computer Science degree can make me a Computer Scientist.
You need C++ for computer science, though!

Be me, a computer scientist who still struggles with XOR.

Lotta infinite sums in loops

I literally have no idea what this picture means, and at this point I'm too afraid to ask.

My ex boss describes himself as such. King of the dickheads.

tbf all good programmers are good at math. Not classic arithmetic necessarily, but at the very least applied calculus. It's a crime how many people used a mathematical discipline every day, but don't think they're "good at math" because of how lazer focused the world is on algebra, geometry and trig as being all that "math" is.
A senior firmware engineer said to the group that we just have to integrate the acceleration of an IMU to get velocity. I said “plus a constant.” I was fired for it.

I have been coding since I was 10 years old. I have a CS degree and have been in professional IT for like 30 years. Started as a developer but I’m primarily hardware and architecture now. I have never ever said I was a computer scientist. That just sounds weird.

wow you have a degree I'm soooooo impressed

good they escaped early

good physics/graphics engine require calculus
How?
Again, legit question.

Had a graduate Dev who did not have a fucking clue about anything computer related. How tf he passed his degree I have no idea.
Basic programming principles? No clue. Data structures? Nope.
We were once having a discussion about the limitations of transistors and dude's like "what's a transistor?" ~_~#

If you want to know how computers work, do electrical engineering. If you want to know how electricity works, do physics. If you want to know how physics works, do mathematics. If you want to know how mathematics works, too bad, best you can do is think about the fact it works in philosophy.

The typical holder of a four-year degree from a decent university, whether it's in "computer science", "datalogy", "data science", or "informatics", learns about 3-5 programming languages at an introductory level and knows about programs, algorithms, data structures, and software engineering. Degrees usually require a bit of discrete maths too: sets, graphs, groups, and basic number theory. They do not necessarily know about computability theory: models & limits of computation; information theory: thresholds, tolerances, entropy, compression, machine learning; foundations for graphics, parsing, cryptography, or other essentials for the modern desktop.
For a taste of the difference, consider English WP's take on computability vs my recent rewrite of the esoteric-languages page, computable. Or compare WP's page on Conway's law to the nLab page which I wrote on Conway's law; it's kind of jaw-dropping that WP has the wrong quote for the law itself and gets the consequences wrong.

Tbh, as a dev knowledge of transistors is about as essential as knowledge about screws for a car driver.
It's common knowledge and in general maybe a little shameful to not know, but it's really not in any way relevant for the task at hand.

If you write them yourself. Then you actually need a bit of math.
But claiming that you need math skills as a programmer because some kinds of programs need you to know maths is like claiming every programmer needs to know a lot about logistics because some people write software for warehouses.

Could be a case of bad memory. Solved the exams and forgot everything in the next hour.

Maybe for dev knowledge, but computer science? The science of computers?
