Search - "discrete mathematics"
Got a call from Google!
Asked for two months to study: Discrete mathematics, Calculus, introductions to algorithms, design patterns, CTCI and linux/unix OS workings in general.
I know I'll be banging my head against the wall and I don't have my expectations too high. But regardless I feel like this is a good excuse to speed up my studies and push myself in the direction I want to go already. It'll be a win-win even if I don't land the position because I'll definitely gain a ton in the process of preparing.
I will be expose to all of this material (except for calculus because I've been learning it for a couple of months) for the first time so I know it'll be a challenge and I am looking forward to it.
If any of you have any tips on good study habits that'll be much appreciated; I currently like to read most of my material and supplement with videos/tutorials... Khan is great but they lack material on discrete mathematics unfortuantely. Thanks in advance!
Wish me luck (:9
Discrete mathematics teacher said "13*37" in the middle of an Euclidean algorithm.
Half the class giggled and the other half just sighed.
These students are your future co-workers.2
Hey DevRant fam ❤️ hope everyone is doing well ! I just finally finished this extremely difficult semester and also my FINAL EXAM!!! no more exams but Projects!! honestly guys and gals this has been my toughest semester yet apart from the time I failed Discrete mathematics twice... and i feel as if i have done well 😁👏🏻.
Anyways guys i hope you’re all doing amazing Wherever you may be!

Hey guys, I have a serious question for you: How do you define science?
And yes this is going to be a long Rant. This topic really pisses me off.
A bit of context first. I come from a "humanities" background. I study history and dude, I love it. The problem is that even though we fucking pull our brains out studying historical phenomena with a fucking ton of conceptual tools, our work is mostly seen as literature to entertain the elderly during their lonely evenings. But that's not really the point of this rant.
My fucking problem is that while we try to do some serious work; actual work that could help society for real, it all goes into that magical fucking kingdom called "humanities". HOW THE FUCK DO THEY DARE TO CALL SOMETHING "HUMANITIES". IT'S A FUCKING HISTORICAL TERM THAT MEANS "TO FULFILL MEN IN ALL IT'S ASPECTS", AND NOW THEY'VE REPURPOSED IT, MAKING IT CONTAIN ANY STUDY THAT ISN'T "EMPIRICAL", "OBJECTIVE", ADD ANY FUCKING SCIENTIFIC DELUSIONARY TERM YOU CAN THINK OF.
And don't get me started on "objectivity". Oh boy, your fucking objectivity is hollow as a kid's balloon. There is no such thing as a objective study, even when it applies your "rational" "godly" scientific method. Some guys follow that shit as if it was a fucking religion. I do understand it's useful and all that, but in the end it's just a tool, you can't fucking define "science" by it's tools.
"""Q: What is carpintery?
A: Well, it's hammers, nails and wood. Yep. Hammers, nails and wood."""
THE SCIENTIFIC METHOD WAS FUCKING INVENTED DURING THE XVIII CENTURY, WHAT THE FUCK DO YOU THINK WAS GALLILEI BEFORE THAT? "HUMANITIES"?
Why do I say objectivity isn't posible? Well, guess what? YOU ARE FUCKING HUMAN. Every thing you know is full of preconceptions and fucking cultural subjectivities invented to understand the world. And it's ok, becouse if you understand your own subjectivity, at least you can see yourself in a critical sense, and at least "tend" to objectivity, in the same way functions tend to infinity.
And here comes the best part: people studying "cs" in my university pass most of the time studying a ton of shit that isn't really science, but is taken as scientific becouse it is related to "science". These guys spend entire semesters just learning programming fundational stuff that in my opinion isn't really science, it's just subjective conceptual constructs built to make the coding process better. They only have TWO fucking classes on discrete mathematics and another 3 or 4 in actual scientific fields related to computing. THESE GUYS AREN'T FUCKING BEING TAUGHT TO BE COMPUTER SCIENTISTS; THEY ARE TEACHING THEM TO BE PROGRAMMERS. THERE'S A HUGE DIFFERENCE BETWEEN CS AND PROGRAMMING AND THAT IS THE WORD SCIENCE. And yes, I'm being drastic on the definition of science on purpose becouse guess fucking what? I'M PISSED OFF.
"Hey, what are you doing?"
"Just doing science with scrum and agile development."
I understand most of you guys would think of science as "the application of the scientific method", "Knowledge by experimentation and peer-review", "anything techy". Guys, science is a lot broather than that. I define it as "the search for truth", mainly becouse that's what we are all doing, and what humans have been doing to gain knowledge through the ages. It doesn't matter what field of truth you are seeking as long as you do it seriously and with fundaments. I don't fucking care if you can't be objective: that's impossible. Just acknowledge it and continue investigating accordingly.
I believe during the last centuries the concept of science has been deformed by the popular rise of both natural and applied sciences. And I love the fact that these science fields have been growing so much all this time, but for fucks sake don't leave every other science (science as I define it) behind. Governments and corporations make huge mistakes becouse they don't treat history, politics and other sciences seriously. Yes, I called history a "science", fuck you.
And yes, by my definition programming is not a science. I don't know what most of you think programming is, but for me it's a discipline that builds stuff, similar to carpintery or blacksmithing. Now if you are pushing the limits, seeking ways to make computing go further, then that's science. The guys that are figuring out AI are scientists, the guys that are using it to detect hotdogs aren't - unless they are the same person- deal with it. I guess a lot of you guys are with me on this point.
In the end, we are all artisans building abstract tools by giving orders to a machine.
I still have some characters left, so I want to thank the community as a whole for letting me vent my inner rage. I don't have much ways to express myself on these matters, so for me DevRant is a bless.8
Does anyone else think discrete math is super satisfying? I love it so much more than algebra or Calc10
Here's my idea. In light of all the efforts to teach kids how to do programming, why not start with an introduction to discrete mathematics instead? From a lot of the programs I've seen, the kids are taught different structures such as if else, while, and for loops, but they don't attempt to start teaching them about recursive methods or even other structures such as linked lists, queues, dequeues, binary trees, heaps, different sorts, and other things. Am I just not looking deep enough into those programs? Or are the creators of these programs not wishing to cover those things because they feel like children wouldn't be able to comprehend such things?4
I am a discrete function. My mood is either a 100 or 0. Nothing in between— especially when I am programming.1
I'm an apprentice software engineer, have been for about a year now. I feel so dumb all the time. Used to be I'd just teach myself at my own pace for about a year or two (which was slow, on and off because of life getting in the way). Now I'm surrounded by programmers with decades more experience than me and I can't help but feel inferior.
I want to get better faster but, I work full-time now so I don't know how to supplement my studying. I've been studying linear-algebra online because my maths is crap and I remember one of my colleagues mentioning that it would be useful. But now I'm not sure because apparently discrete mathematics is better.
I also need to keep up with Java since that's what I'm learning in university but, I'm mostly using React/Typescript in my current project. By the time I finish work I don't even want to look at a line code and I lack the self-discipline to force myself to study in the evening.
I need to pick a direction and stick with it but, it's seems to just be increasingly harder as I've gone on.3
How’s school going?
Well I’m in discrete mathematics and summations honestly suck, but if you put it in a for loop it’s so easy6
Sooooo... I'm not sure I passed my first exam. I would've been able to answer all the questions correctly, if I'd had enough time.1
Hello, I am currently taking BS Computer Science and for this semester we are required to take a subject on Discrete Mathematics (logic).
My question is, how can I apply this knowledge in programming?
