Tips for all the programmers out there:
- A programmer is not a PC repair man, just no one seems to remember about that
- Programming is thinking, not typing.
Counting starts from zero, not one.
- Even after completing a degree and courses and working on IT projects, learning never stops. If you want to stay competitive you should also work on personal projects that force you to use languages and software you never work with on the job.
- You don’t need serious math skills to be a developer. However, you’ll need basic algebra, logic, strong problem-solving skills, and most of all, patience.
- You don’t need a degree to be a developer - programming is like almost any profession: if you’re good at it, people will pay you for your skills, regardless of how you got there.
- Sleeping with a problem, can actually solve it.14 -
Please stop recommending arch. For real. Stop!
Let's back up. I'm an arch user. Have been for years. I love arch! Like hardcore! But for real, cut it out.
Either they didn't ask and you're being obnoxious or they probably asked "what's a good distro to learn?" Or "Ubuntu holds my hand too much, I want something more consoley" either way, arch is not the answer. Arch is a distro for us stuck up types who like spending all day fixing dependency errors, changing our WM every other week, debating the merits of X vs wayland, and acting better than everyone else.
But here's the thing: I found arch because I wanted something that I could compulsively configure and get really in the weeds. I think most arch users feel that way to some degree. You kinda have to if you want to not be miserable. But many Linux users aren't like that. And that's fine! Let them use mint, or Debian. So they never change their DE. Cinnamon is a great interface! Gnome 2 is totally fine! There's literally nothing wrong with being content with sane defaults and not manually installing every package, and having scheduled releases from a stable source.
Do you tell 7th graders "if you really want to get better at algebra, you should try calculus. You really gain a deep knowledge of math!" No! They will get there when they are good and ready! Or not. It's not a beginner distro. In fact (controversial opinion ahead) it's pretty shitty at being a distro. I have used arch for years! But I don't recommend it to anyone. Because if you want to configure a box for literally 100s of hours (it's never really over is it?), Then you aren't asking anyone about distro recommendations. You've tried them all. You've heard of arch. You been to /r/unixporn.
Stop acting better than everyone else and stop telling people it's better than <other distro here>. It's not. It's different. Very different. And it's not for everyone.26 -
About six months ago I decided I wanted to learn to write a neural network from the ground up, using only the C++ standard lib. Had to learn some linear algebra, multivariable calc and a dash of wizardry.
The mathematics of neural networks is still one of the coolest things I've ever learnt. It still marvels me that you can make a specialized mini-brain out of nothing but numbers.17 -
To become an engineer (CS/IT) in India, you have to study:
1. 3 papers in Physics (2 mechanics, 1 optics)
2. 1 paper in Chemistry
3. 2 papers in English (1 grammar, 1 professional communication). Sometimes 3 papers will be there.
4. 6 papers in Mathematics (sequences, series, linear algebra, complex numbers and related stuff, vectors and 3D geometry, differential calculus, integral calculus, maxima/minima, differential equations, descrete mathematics)
5. 1 paper in Economics
6. 1 paper in Business Management
7. 1 paper in Engineering Drawing (drawing random nuts and bolts, locus of point etc)
8. 1 paper in Electronics
9. 1 paper in Mechanical Workshop (sheet metal, wooden work, moulding, metal casting, fitting, lathe machine, milling machine, various drills)
And when you jump in real life scenario, you encounter source/revision/version control, profilers, build server, automated build toolchains, scripts, refactoring, debugging, optimizations etc. As a matter of fact none of these are touched in the course.
Sure, they teach you a large set of algorithms, but they don't tell you when to prefer insertion sort over quick sort, quick sort over merge sort etc. They teach you Las Vegas and Monte Carlo algorithms, but they don't tell you that the randomizer in question should pass Die Hard test (and then you wonder why algorithm is not working as expected). They teach compiler theory, but you cannot write a simple parser after passing the course. They taught you multicore architecture and multicore programming, but you don't know how to detect and fix a race condition. You passed entire engineering course with flying colors, and yet you don't know ABC of debugging (I wish you encounter some notorious heisenbug really soon). They taught 2-3 programming languages, and yet you cannot explain simple variable declaration.
And then, they say that you should have knowledge of multiple fields. Oh well! you don't have any damn idea about your major, and now you are talking about knowledge in multiple fields?
What is the point of such education?
PS: I am tired of interviewing shitty candidates with flying colours in their marksheets. Go kids, learn some real stuff first, and then talk some random bullshit.18 -

Two years ago I moved to Dublin with my wife (we met on tour while we were both working in music) as visa laws in the UK didn’t allow me to support the visa of a Russian national on a freelance artists salary.
After we came to Dublin I was playing a lot to pay rent (major rental crisis here), I play(ed) Double Bass which is a physically intensive instrument and through overworking caused a long term injury to my forearm which prevents me playing.
Luckily my wife was able to start working in Community Operations for the big tech companies here (not an amazing job and I want her to be able to stop).
Anyway, I was a bit stuck with what step to take next as my entire career had been driven by the passion to master an art that I was very committed to. It gave me joy and meaning.
I was working as hard as I could with a clear vision but no clear path available to get there, then by chance the opportunity came to study a Higher Diploma qualification in Data Science/Analysis (I have some experience handling music licensing for tech startups and an MA with components in music analysis, which I spun into a narrative). Seemed like a ‘smart’ thing to do to do pick up a ‘respectable’ qualification, if I can’t play any more.
The programme had a strong programming element and I really enjoyed that part. The heavy statistics/algebra element was difficult but as my Python programming improved, I was able to write and utilise codebase to streamline the work, and I started to pull ahead of the class. I put in more and more time to programming and studied personally far beyond the requirements of the programme (scored some of the highest academic grades I’ve ever achieved). I picked up a confident level of Bash, SQL, Cypher (Neo4j), proficiency with libraries like pandas, scikit-learn as well as R things like ggplot. I’m almost at the end of the course now and I’m currently lecturing evening classes at the university as a paid professional, teaching Graph Database theory and implementation of Neo4j using Python. I’m co-writing a thesis on Machine Learning in The Creative Process (with faculty members) to be published by the institute. My confidence in programming grew and grew and with that platform to lift me, I pulled away from the class further and further.
I felt lost for a while, but I’ve found my new passion. I feel the drive to master the craft, the desire to create, to refine and to explore.
I’m going to write a Thesis with a strong focus on programmatic implementation and then try and take a programming related position and build from there. I’m excited to become a professional in this field. It might take time and not be easy, but I’ve already mastered one craft in life to the highest levels of expertise (and tutored it for almost 10 years). I’m 30 now and no expert (yet), but am well beyond beginner. I know how to learn and self study effectively.
The future is exciting and I’ve discovered my new art! (I’m also performing live these days with ‘TidalCycles’! (Haskell pattern syntax for music performance).

I've found sites like Udemy/Khanacademy/Codecademy/Brilliant/Edx to be very useful — possibly more useful than expensive education.
But they still need:
1. Better correction/update mechanisms. Human teachers make mistakes and material gets outdated, and while online teachers are rectified faster than classroom teachers, the procedure is still not optimal. Knowledge should be a bit more like a verified wiki.
2. Some have great interactive coding environments, some have great videos, some have awesome texts, some have helpful communities. None has it all. In the end, I don't want to learn a new language by writing code in my browser. It could all be integrated/synced to the point where IDEs have plugins which are synced to online videos, with tests and exercises built in, up to a social network where you could send snippets for review and add reviews to other people's code.
3. Accreditation. Some platforms offer this against payment, but I think those platforms often feel very old school (pun intended), with fixed schedules, marks and enrollments. Self paced is a must.
4. Depth is important. Current online courses are often a bit introductory. We need more advanced courses about algorithms, theoretical computer science, code design, relational algebra, category theory, etc. I get that it's about supply/demand, but we will eventually need to have those topics covered.
I do believe that for CS, full online education will eventually win from the classroom — it's still in its infancy, but has more potential to grow into correct, modern education.10 -
Ooh this is good.
At my first job, i was hired as a c++ developer. The task seemed easy enough, it was a research and the previous developer died, leaving behind a lot of documentation and some legacy fortran code. Now you might not know, but fortran can be really easily converted to c, and then refactored to c++.
Fine, time to read the docs. The research was on pollen levels, cant really tell more. Mostly advanced maths. I dug through 500+ pages of algebra just to realize, theres no way this would ever work. Okay dont panic, im a data analyst, i can handle this.
Lets take a look at the fortran code, maybe that makes more sense. Turns out it had nothing to do with the task. It looped through some external data i couldnt find anywhere and thats it. Yay.
So i exported everything we had to a csv file, wrote a java program to apply linefit with linear regression and filter out the bad records. After that i spent 2 days in a hot server room, hoping that the old intel xeon wouldnt break down from sending java outputs directly to haskell, but it held on its own.1 -
Today in algebra I got bored and wrote "<hand>" on the back of my hand and "</hand>" on the top of my wrist, I feel proud of myself and I also question why I do things like this.4

Most kids just want to code. So they see "Computer Science" and think "How to be a hacker in 6 weeks". Then they face some super simple algebra and freak out, eventually flunking out with the excuse that "uni only presents overtly theoretical shit nobody ever uses in real life".
They could hardly be more wrong, of course. Ignore calculus and complexity theory and you will max out on efficiency soon enough. Skip operating systems, compilers and language theory and you can only ever aspire to be a script kiddie.
You can't become a "data scientist" without statistics. And you can never grow to be even a mediocre one without solid basic research and physics training.
Hack, I've optimized literal millions of dollars out of cloud expenses by choosing the best processors for my stack, and weeks later got myself schooled (on devRant, of all places!) over my ignorance of their inner workings. And I have a MSc degree. Learning never stops.
So, to improve CS experience in uni? Tear down students expectations, and boil out the "I just wanna code!" kiddies to boot camps. Some of them will be back to learn the science. The rest will peak at age 33.17 -
math be like:
"Addition (often signified by the plus symbol "+") is one of the four basic operations of arithmetic; the others are subtraction, multiplication and division. The addition of two whole numbers is the total amount of those values combined. For example, in the adjacent picture, there is a combination of three apples and two apples together, making a total of five apples. This observation is equivalent to the mathematical expression "3 + 2 = 5" i.e., "3 add 2 is equal to 5".
Besides counting items, addition can also be defined on other types of numbers, such as integers, real numbers and complex numbers. This is part of arithmetic, a branch of mathematics. In algebra, another area of mathematics, addition can be performed on abstract objects such as vectors and matrices.
Addition has several important properties. It is commutative, meaning that order does not matter, and it is associative, meaning that when one adds more than two numbers, the order in which addition is performed does not matter (see Summation). Repeated addition of 1 is the same as counting; addition of 0 does not change a number. Addition also obeys predictable rules concerning related operations such as subtraction and multiplication.
Performing addition is one of the simplest numerical tasks. Addition of very small numbers is accessible to toddlers; the most basic task, 1 + 1, can be performed by infants as young as five months and even some members of other animal species. In primary education, students are taught to add numbers in the decimal system, starting with single digits and progressively tackling more difficult problems. Mechanical aids range from the ancient abacus to the modern computer, where research on the most efficient implementations of addition continues to this day."
And you think like .. easy, but then you turn the page:

Mother fucking SQL, fuck mathematicians, fuck every thing!
So let's supose we'd only need the first char of a string. Every, and I mean fucking every (php, java, javascript, ruby, python, haskell) fucking language, uses something like `substring(input, 0, 1)` as it knows the input is nothing more than a fucking array of chars, otherwise known as motherfucking String. Logically the offset for the first char is 0.
Enter SQL, there you need to put `SUBSTRING(input, 1, 1)` because fuck every one! Fucking math guys who developed relational algebra on which (most) databases are based on (I love you for it, but come on you fuckers!), Decided that the first character should be at position 1...

I've been taking a bunch of boot camp 'entry' type tests to do some research for the school I'm building - and these things are strange.

Dear Microsoft Kusto Query Language (KQL)
Screw you. You suck like more than a sudden depressurization event in an airplane. Creating your own freaking query language is bad, the people who invented SQL based it on a the principles of mathematical relational algebra, which although confusing, and not suited for all use cases is at least consistent.
You were invented by a bunch of oxygen deprived halfwits based on the principles of sadism and incompetence.
The only situation in which I would voluntarily use KQL as my tool of choice is if my purpose was to extract a Dantesque style revenge on someone who had committed grievous harm to myself and my family members. In that case forcing them to work with you day in and day out would still border on cruel and unusual punishment.
Sincerely, A developer who has spent the past 2 hours dealing with your Lovecraftian madness.
P.S. I hope you choke on a raw chicken bone and no one gives you CPR.3 -
From NAND to Tetris..
This book is IMO the best book for those who want to venture to the lower level programming.
This books retrains you’re thinking, teaches you from the bottom up! Not the typical top down approach.
You begin with the idea of Boolean algebra. And the move on to logic gates.. from there you build in VHDL everything you will use later.
Essentially building your own “virtual machine”.. you design the instruction set. Of which you will then write assembly using the instruction set to control the gate you built in VDHL.
THEN you will continue up the abstraction layer and will learn how a compiler works, and then begin written c code that is then compiled down to your assembly of your instructions set to be linked and ran on your virtual machine you built.
All the compiler and other tools are available on the books website. The book is not a book where you copy and paste, run and done.... you kinda have to take the concepts and apply them with this book.
Then once you master this book, take it the extra step and learn more about compilers and write your own compiler with the dragon book or something.
Fantastic book, great philosophy on teaching software.. ground up rather than top down. Love it! It’s Unique book.

I've actually had mostly good instructors for CS. Or at least mediocre. The worst teacher I had was actually my Algebra II teacher in high school. She taught by reading, word for word, from our textbook. She would copy the example problems from that chapter onto the whiteboard. And then give us the rest of class to work on homework. She was basically a Text-to-Speech program for our textbook.
We all joked that she was drunk and the one locked cabinet in her classroom contained liquor. A year after I had her class she was fired. For drinking on the job. The joke turned out to be 100% true and they actually did find alcohol in the locked cabinet. -
Being a programmer in a scientific discipline can be infuriating.
using "no one" ="almost no one"
using everyone = "almost everyone"
1. No one knows what even the very idea of good practice is. And everyone refuses to learn. 3k lines of repetitive copy pasted main. 500 lines of plotting method.
2. Raw C-style pointer based array creation. Won't use develope array libraries because what if development stops. FUCKING HAVE YOU SEEN YOUR CODE WHAT IF DEVELOPMENT ON YOUR CODE STOPS. FUCK.
3. LOOP VARIABLES DECLARED AT THE BEGINNING OF THE METHOD WHY.
4. Everyone wants to make modular, independent code. No one wants to use OOP. NOPE. ALL IN ONE FILE. WRITE C++ LIKE A FUCKING PYTHON NOTEBOOK. FUCK.
5. LIBRARIES OH MY GOD PLEASE DO NOT CODE UP YOUR MATRIX MULTIPLICATION. PLEASE DO NOT TRIPLE LOOP IT. NO. THE LINEAR ALGEBRA LIBRARY WILL STAY IN DEVELOPMENT.
6. Please realize that literally not one comment over an 1800 line file does not help anyone.
FUCKING. WHY. WHY ARE WE SCIENTISTS SO GOOD AT SCIENCE AND SO FUCKING SHIT AT THE CODE THAT MAKES OUR SCIENCE HAPPEN. WHY. FUCKING. WHY. FUCK.4 -

The more I learn about advanced C++ the more I love this language. C++'s template system is so insanely cool!

So I had a PhD interview with a very good group, and it was downright a catastrophe. I mean, questions on abstract algebra...

Ooh yeeaah. It was 2020 and I was in a final exam. Algebra and Analytical Geometry; 1st year of Engineering class, if you care.
I had a camera pointing at me, my desk and my computer.
The submission was through Google Drive.
So I use my phone to scan my test into a PDF, upload it, and when I tried to submit it...
My recent documents were full of nudes of Belle Delphine.
I had forgotten a friend sent that while we were on Discord having some laughs earlier and I clicked it to check.
I selected my exam, submitted it, and went on with it.
I don't know if anyone noticed, but I think it was kind of obvious, even if it was a screen in a camera... the previews were kinda big on my big screen.2 -
First year: intro to programming, basic data structures and algos, parallel programming, databases and a project to finish it. Homework should be kept track of via some version control. Should also be some calculus and linear algebra.
Second year:
Introduce more complex subjects such as programming paradigms, compilers and language theory, low level programming + logic design + basic processor design, logic for system verification, statistics and graph theory. Should also be a project with a company.
Year three:
Advanced algos, datastructures and algorithm analysis. Intro to Computer and data security. Optional courses in graphics programming, machine learning, compilers and automata, embedded systems etc. ends with a big project that goes in depth into a CS subject, not a regular software project in java basically.4 -

A company took their technical test on this really weird website. There was a Windows Narrator guy's voice giving instructions while a timer was running. I had to flash my ID to the webcam and then fit my head on an outline on the screen. It was for a web dev position. I had to speak into the microphone to answer the Narrator's questions and then send the video to them. The questions were weird and hypothetical, mostly. I just thought that their process was dumb and unnecessary.

I don't like aptitude and algebraic tests. One company, I remember, had their test on Google Forms. For some multiple choice questions, they put check boxes instead of radio buttons. So, I could just blaze through it selecting all options. Some of the questions had their first option as "All of the above" 🤔. Fortunately, I didn't pass the test.

The company I'm interning with, starting from next month, had a good interview process. They asked me questions on JavaScript, CSS, and a few on algorithms and data structures. I was also given a task where I had to make a css animation of trees. I'm glad they didn't have an algebra entry test.

I found this on a wiki with Haskell Humor... it's interesting...
How to Shoot Your Self in the Foot With Haskell: Putting the unsafe in unsafePerformIO!
You shoot the gun, but the bullet gets trapped in the IO monad.
Couldn't match expected type 'Deer' against inferred type 'Foot'.
While compiling your program the compiler produces a type error long enough to overflow a kernel buffer, overwrite the trigger control register and shoot you in the foot.
After trying to decipher the type errors from the compiler, your head explodes.
After you've finally found a way to circumvent the type system and shoot yourself in the foot, Oleg appears out of nothing and shoots you in the foot for coming up with it before him.
You shoot the gun but nothing happens (Haskell is pure, after all).
Your foot is fine, until you try to walk on it, at which point it becomes mangled.
You have a shootFoot function which you've proven correct. QuickCheck validates it for arbitrary you-like values. It will be evaluated only when you end up at the hospital. You hope this doesn't come to pass, as it actually returns a bullet-ridden copy of yourself and you don't want to be garbage-collected.
foreign import ccall "shootparts.h shootfoot" shoot_foot :: Gun -> Programmer -> IO ()
shootSelfInFoot = unsafePerformIO . shoot . foot $ self -- Shoot self in foot 0 or more times depending on evaluation order
No instance for (Target Foot)
arising from use of `shoot' at SelfInflictedInjury.hs:1:0
Possible fix: add an instance declaration for (Target Foot)
In the expression: shoot foot
You go to shoot yourself in the foot but the bullet is in the ST monad and the gun is in the IO monad, so you can't.
You ask Haskell to shoot you in the foot but by the rules of lazy evaluation you don't need the result yet so it doesn't happen.
You decide to shoot yourself in the foot but get distracted devising a ballistics algebra and wondering if you can do the calculations in the type system.
You want to shoot yourself in the foot but realize there is no Gun datatype so use Arrows instead.
You shoot in the direction of your foot, but since you are inside the STM monad you can just retry until you figure out what to do.
You shoot yourself in the foot, but you are perfectly fine as long you just don't evaluate the foot.
You shoot yourself in the foot, but nothing happens unless you start walking.
Don't forget about memory consumption! If you don't look, the bullet causes heap overflow. If you look, the bullet causes stack overflow.
You *appear* to have deliberately shot yourself in the foot, and yet your program actually runs perfectly OK due to lazy evaluation. (So long as you remember to not look at your foot...)
You aim the gun at your foot, pull the trigger and remove the clip. When you look at your undamaged foot, the hammer clicks on an empty barrel.1 -
Ok now I'm gonna tell you about my "Databases 2" exam. This is gonna be long.
I'd like to know if DB designers actually have this workflow. I'm gonna "challenge" the reader, but I'm not playing smartass. The mistakes I point out here are MY mistakes.
So, in my uni there's this course, "Databases 2" ("Databases 1" is relational algebra and theoretical stuff), which consist in one exercise: design a SQL database.
We get the description of a system. Almost a two pages pdf. Of course it could be anything. Here I'm going to pretend the project is a YouTube clone (it's one of the practice exercises).
We start designing a ER diagram that describes the system. It must be fucking accurate: e.g. if we describe a "view" as a relationship between the entities User and Video, it MUST have at least another attribute, e.g. the datetime, even if the description doesn't say it. The official reason?
"The ER relationship describes a set of couples. You can not have two elements equal, thus if you don't put any attribute, it means that any user could watch a video only once. So you must put at least something else."
Do you get my point? In this phase we're not even talking about a "database", this is an analysis phase.
Then we describe the type dictionary. So far so good, we just have to specify the type of any attribute.
And now... Constraints.
Oh my god the constraints. We have to describe every fucking constraint of our system. In FIRST ORDER LOGIC. Every entity is a set, and Entity(e) means that an element e belongs to the set Entity. "A user must leave a feedback after he saw a video" becomes like
For all u,v,dv,df,f ( User(u) and Video(v) and View(u, v, dv) and feedback(u, v, f) ) ---> dv < df
provided that dv and df are the datetimes of the view and the feedback creation (it is clear in the exercise, here seems kinda cryptic)
Of course only some of the constraints are explicitly described. This one, for example, was not in the text. If you fail to mention any "hidden" constraint, you lose a lot of points. Same thing if you not describe it correctly.
Now it's time for use cases.
You start with the usual stickman diagram. So far so good.
Then you have to describe their main functions.
In first order logic. Yes.
So, if you got the point, you may think that the following is correct to get "the average amount of feedback values on a single video" (1 to 5, like the old YT).
(let's say that feedback is a relationship with attribute between User and Video
getAv(Video v): int
Let be F = { va | feedback(v, u, va) } for any User u
Let av = (sum forall f in F) / | F |
return av
But nope, there's an error here. Can you spot it (I didn't)?
F is a set. Sets do not have duplicates! So, the F set will lose some feedback values! I can not define that as a simple set!
It has to be a set of couples, like (v, u), where v is the value and u the user; this way we can have duplicate feedback values in our set.
This concludes the analysis phase. Now, the design.
Well we just refactor everything we have done until now. Is-a relations become relationships, many-to-many relationships get an "association entity" between them, nothing new.
We write down on paper every SQL statement to build any table, entity or not. We write down every possible primary key or foreign key. The constraint that are not natively satisfied by SQL and/or foreign keys become triggers, and so on.
This exam is considered the true nightmare at our department. I just love it.
Now my question is, do actually DB designers follow this workflow? Or is this just a bloody hard training in Pai Mei style?6 -

Soooo I have greatly underestimated the value of the shit you can learn in Kaggle, both from the projects that people do and from the learning section that they have. I wouldn't exactly classify them as beginner level or for complete newbies.
By default, if you wanna go and learn about ML then be trady to have some mathematical background to at least the level of Linear algebra, statistics and some basic calculus, everything else can be learned as you go along.
But ye, shit is fucking cool man, they have sooo many cool projects in it. I learned from academic shit in uni and a fuckload of books, but i dig this approach sooo much more.

How ignorant we all are about the world. It's not necessarily a bad thing, just a fact. After a four year degree I've learnt so much, how a computer works from the physical phenomena on the hardware level to the inner workings of an OS to the highest level abstractions of modern web development, a wide array of programming languages covering several different paradigms, mathematics from calculus to statistics to algebra, how to work with databases, how to administrate a server, how to build a website, and much more.
And that's just in a degree. I have knowledge in one domain and I wouldn't even call myself an expert in it. Medicine, physics, biology, the hundreds of branches of engineering from civil to nautical to aerospace to automobile, to geology to meteorology to astronomy, to the practical application of this knowledge in hundreds of trades. There's so much more to know in so much depth and only recently have I realized how little we all know on an individual level.
Finding this out has been a mixed bag, on the one hand it's made me value what I know and what others can teach me a hell of a lot more, on the other, knowing that people haven't realized this and adamantly discuss and impose from a position of ignorance isn't very nice.
tl;dr I know that I know nothing3 -

Develop my first mobile app with a restful backend for consumer usage
Learn more about cloud architecture/computing
Finish learning calculus
Learn linear algebra, discrete math, statistics and probability
Maybe start ML this year depending on math progress and time2 -
float integral = 0;
float dx=float.minValue;
for (float x = a; x<=b; x+=dx) {
integral+=f(x)*dx;
}
A classmate just literally wrote this and he believed it was the proper way to do it.
I asked him to integrate f(x)=1 on 0<x<1. -
During my studies on the university, while preparing for the linear algebra exam I had a dream where I was a matrix in the Jordan normal form.5
-
I just cant Wrap my head around matrices and linear Algebra.
I am currently doing a uni course about this and need to implement some eigenvalue solvers. I somehow manage to implement the stuff with the help of pseudocode and the internet but I have nö idea conceptually what all these things like norms, eigenvalues, conditioning etc are supposed to tell me and why.
How do people handle this so naturally?8 -
I'm so glad that I got a CS degree learning Data Structures, Algorithms, Operating systems, Databases, Linear Algebra, Software Engineering, Networking and many more...
How else would I have been able to center a div with CSS or change the Background color?2 -
What if I told you that algebra, geometry, precalculus's (ect) laws are the equivalent of api/documentation. we learn them and use them when necessary to solve problems. I will use the quadratic formula in math to solve a problem just like I would use a particular function in programming.
-
You know shit is going to hit the fan if the sentence "c++ is the same as java" is said because fuck all the underlying parts of software. It's all the fucking same. Oh and to write a newline in bash we don't use \n or so, we just put an empty echo in there. And fuck this #!/bin/bash line, I'm a teacher. I don't need to know how shit works to teach shit. Let's teach 'em you need stdio for printf even tho it compiles fine without on linux (wtf moment number one, asking em leaves you with "dunno..") and as someone who knows c you look at your terminal questioning everything you ever learned in your whole life. And then we let you look into the binaries with ldd and all the good stuff but we won't explain you why you can see a size difference in the compiled files even tho you included stdio in the second one, and all symbol tables show the exact same thing but dude chill, we don't know what's going on either.
Oh and btw don't use different directory names as we do in our examples. You won't find your own path, there is no tab key you can press to auto-fill shit.
But thats not everything. How about we fill a whole semester with "this is how to printf" but make you write a whole game with unity and c#. (not thaught even the slightest bit until then btw)
Now that you half-assed everything because we put you in a group full of fucks who don't even know what a compiler is but want to tell you you don't know shit and show you their non-working unfinished algorithms in some not-even-syntax-correct java...
...how about we finally go on with Algebra II: complex numbers, how they are going to fuck up your life, how we can do roots of negative numbers all of the sudden and let you do some probability shit no one ever fucking needs. BUT WHY DON'T YOU KNOW EVERYTHING ALREADY HMMMMM, IT'S YOUR SECOND LESSON, YOU WENT TO SCHOOL PLS BE A MATH PRO ASAP CUS YOU NEED IT SO MUCH BUT YOU DON'T NEED TO KNOW PROPER SYNTAX, HOW MEMORY MANAGEMENT WORKS, WHAT A REFERENCE IS AND PLS FINALLY FORGET THE WORD "ALLOCATION" IT DOESN'T PLAY A SINGLE ROLE YOU ARE STUDYING SOFTWARE DEVELOPMENT WHY ARE YOU SO BAD AT ECONOMICS IT MAKES NO SENSE I MEAN YOU HAD A WHOLE SEMESTER OF HOW TO GREET SOMEONE IN ENGLISH, MATHS > ECONOMICS > ENGLISH > FUCKING SHIT > CODING SKILL THATS HOW THE PRIORITIES WORK FOR US WHY DON'T YOU GET IT IT MAKES SO MUCH SENSE BRAH4 -
When I was in seventh grade, I learned to solve quadratic equations and how to convert from standard form to vertex form
Today, when I had to convert a quadratic equation, I completely blanked on how to do it
I can’t remember how to do math seventh graders know

So I am trying to implement a deep learning paper.
And I started reading, It's fucking unbelievable
First page: maybe I will get it in the second page!!
Second page: what did I miss from the first page?
Third page: Woohw, let me start over.
Now: I am reading about linear algebra and basic probability theories.
I guess this is is why not anyone can be on deep learning research areas and not used by many developers.4 -
Linear algebra is a hammer that actually works well on things akin to a nail when wielded right. Do you have a similar wildcard that works everytime you try it?2
-
I have found that once you work for a company where you have to implement everything in its raw form using the raw language and raw logic, you really have to know what you're doing and knowing some basic/medium programming and having some algebra knowledge doesn't cut it (unlike some people think).
I've been at two sides of the coin: I worked for a company that had everything in place, a framework that handled all edge cases and what not and I just had to focus on user stories, but I also worked for a company where I had to do everything manually.
For example, at the latter company I had to know Discrete Mathematics; truth tables to their most convoluted and disgusting form, having to be able to apply this on a late Friday night with a headache and lack of food and sleep with the PM stressing out.
I've had to deal with NOT AND OR AND OR AND OR AND branches or whatever, where an OR behaves like an AND and if you want a value between an AND AND and an OR, you'd have to do a NOT OR.. to think about latches, all in my head, sigh, anyway, within limited time constraints, without even having time to write tests, having to make sure that everything checks out while the client is breathing down my neck. Yeah, not such fun times.
I'm happy for those of you who can just write some moderately difficult logic but you don't have to break your head over doing everything manually, as if you're in the coding stone age and nothing is taken care of.
Companies like these make me want to run away.3 -
NO FUCKING WONDER I SUCKED-ASS IN HIGH SCHOOL ALGEBRA!!!!!
Arghgghhghgh ughhh....
I want to beef up the hell out of my Maths Chops so I can maybe try going back to school for a A.S. in EE or hell even an B.S.
I'm using my company's Safari Learning account for getting free-ish access to college algebra books and I'm self studying.
I'm still in Chapter 0 where the book covers shit you're supposed to know from previous years of education. I'm just learning about some of this shit now!!!
While it's possible that I didn't pay attention in high school lectures, I took geometry in 9th grade and was an A/B+ student and felt confident in maths. I got to Algebra II in High School and suddenly nothing made sense anymore, reality fucking-fell-apart!
Suddenly, I'm failing tests left and right and struggling with the lecture concepts and I could never seem to grasp materials covered in class anymore to even be able to finish the homework assignments.
Fast forward to me being 15 years older and wanting to take a stab at this shit again, but with new found determination to get into EE so I can fuck around with small electronics for pet projects I want to do. I'm starting with College Algebra to try and learn when suddenly, low and behold I have a HUGE FUCK-MOTHERING GAP in my core understanding of the language/syntax/grammar of mathematics.
Been fucking knee-capped for the last decade+ because I either slacked off during those fundamental lectures (which again; is totally plausible) or I had a complete fucking imbecile for a math teacher that glossed over the topics and fucked not only me but the 40+ other kids in that class.
I'm not going to blame the teacher, although I really fucking want to, but I can't remember how the class scored on tests or homework to be able to fairly and objectively make that judgement against the educator.
FUCK!!! I hate my 15 y.o. self right now6 -
I once saw a DBA using two for loops in PL/SQL to join two tables. I wonder if he knew about the "alternative" way to do that...2
-
Co-worker: "You don't need to know the math! Stop going on about it."
Me: "I think you do for some things, my algebra is not good at all, I need to improve it a lot and I just think you should too."
Co-worker: "Oh stop it, If the code runs it's OK!"
Me: "Well yeah, the code runs but you're over-fitting like a mad man and have a P-value of a bejillion."
Co-worker: "What!?"
"data scientist" -
Lots of good suggestions up in here.
My personal prefference:
Such as there are governing bodies indiciating how a programming language evolves and a web consortium...there should be a computer science one. That dictates fundamental approaches covering everything that belongs to this wonderful branch of science. Everything from math to differenr scientific branches all the way down to turtles. And for it to be standarized and updated. Indeed, if you want to spend your entire existence gobbling js in the form of web sites then that is fine, but you should have sufficient knowledge to branch out into more academic pursuits if required.
Also, updated tools would be better, every aspiring computer scientist shall be able to navigate through all major operating systems and programming environments regardless of their beliefs and or prefferences and schools should provide said environments in their classrooms.
Data Strucrutes and Algorithms should be a must. Software engineering principles should be a must. Calculus, Algebra and Statistics as well as Physica should be a must.
And succesfully navigating over different engineering areas should be a must.
Not to cleanse the industry. Fuck your elitist mentality. If you think that programming is a sacred art that should exclude people then I really hope you fucking disapear from existence. No, not to cleanse. But to expand the industry and maybe show people that there is more than fucking around between node modules or gemsets.
Peace pendejos
**drops your mom's fatass...i mean mic** -
Started at a new college once again after a long pause.
And I have to admit that I suck at basic stuff like algebra. Shit...
I'm putting a lot of time to understand things, but it feels like the knowledge just fades away. Starting to doubt myself...
Not hoping for anyone to support me either, just felt like posting so that I won't keep thinking about it and giving myself bad vibes.7 -

Going through my graduate program I have come to realize that there is more to A.I than just machine learning algorithms. As if ML was not complicated enough, we add more to it such as KRR and other topics that border on the areas of Cognitive Science, Boolean Algebra, Logic and even Philosophy and you know what? I dig it. I dig it because finding some of the information in the course that I am getting is damn near impossible to see in other items. Such is the case as a method for fucking signature unit propagation which afuckingparently was developed by one of my instructors(not complaining, just really fucking impressed)
The thing is, most of these items would normally have a parallel in software development that we use on our day to day basis, all of us, no matter if you do web, systems development, database development whatever, the general concepts are the same: you represent real world concepts, such as that of logic and knowledge in programatic/mathematical representations.
I am really amazed at the content of these items, I really am. I just wish for some clarification on ambiguity, seems like most things are left better if it where explained in a programmer's point of view. Most of the items that I have seen could have easily been summarized in a programmers logic if only they would have preferred to take the time to do it, and I get that there needs to be mathematical intuition formulated before anything, it is better sometimes to learn concepts from an outside point of view, a mathematical point of view, but shit is just strange sometimes.1 -
Giving a tensorflow workshop and the thing people struggle the most is the Linear Algebra behind it... it is only gradients in tensor and some matrix multiplication.
My recommendation is: do you want to work with Deep Learning algorithms? Y'all need Linear Algebra, not PhD, just a bit! -
So my Algebra 2 teacher won't give students credit without showing work (You can literally make a 600/600 on the final with writing a thing down). I've decided that I'm going to create a program for everything that she assigns me, so that if she asks for the work, I can show her the source code.2
-
So... IT was fucking horrific. Just the sight of red and white makes my heart race. (It was a great movie though; if you're into horror I highly recommend watching it)
However, I'm afraid to go to sleep tonight so I'll probably just stay up all night coding and studying for my CSIII exam on Monday.
SERIOUS QUESTION: as developers, do you ever use base conversions or boolean algebra? I'm trying to figure out how what we're learning will actually apply to the real world.4 -
First and foremost, students should be carefully taught the logic and mentality behind programming. Most of the time I see that the introductory programming courses waste so much energy in teaching the language itself. So students kinda just get fucked cause many people end up ending the course without having actually gained the "programming perspective".
Stop teaching pointers and lambdas and even leave the object oriented stiff till later. If a student doesn't know why we use a For loop then how can they learn anything else.
I believe once that thing in your brain clicks about programming, everything goes smooth from there... kinda :P
Second of all, and this pertains mainly to the engineering and science disciplines.
We need a fundamental and strong mathematical foundation. And no I don't mean taking fucking double integrals. Teach us Linear Algebra, Graph theory, the properties of matrices, and Probability theory.
One of the things I suffered from most and regret in university is having a weak foundation in math and having to spend more time catching myself up to speed.
It's so annoying reading a paper on a new algorithm or method and feeling like an idiot because I can't understand what magic these people did.
Numerical Methods...
Ok this is more deeper, maybe a 2nd year course.
But this is something we take for granted.
Computers don't magically add and subtract and multiply.
They fuck up.
And it'll bite you in the ass if you're not even aware that the computer we all love so much isn't as perfect as we think
Some hardware knowledge.
Probably a basic embedded systems course with arduinos
just so you can get a feel for how our beautiful software actually makes those electrons go weeeeeeeee
And finally
Practice practice
Projects projects
like honestly
just give me the internet and some projects
Ill learn everything else
Projects are the best motivation
I hate this purely theoretical approach
where we memorize or read code and write these stupid exams
Test what we are capable off
make us do projects that take sleepless nights and litres of coffee
And judge our methods, documentation, team work, and output
Team work skills and tools (VCS, communicating, project management, etc.)
Documentation and Reporting
Properly
:)
maybe even with LaTeX :D
Yeah that's the gist of whats on my mind at the moment regarding an ideal computer science education
At least the foundations
The rest I leave it to the next dude. -
I am going to start studying linear algebra but not sure which book I should use. I have a hard copy of Linear Algebra and its Applications. But I don't know wheater its good or bad. Should I use it or look for another book?9

Urgh.. the amount of things you have to know as a developer.. it can get stressful and frustrating sometimes when (in-depth) technology knowledge is demanded from you (for instance, for a job position)..
It's like being a doctor, being a lifelong student.
A few examples of what I had to know during my career:
Java, .NET, Python, PHP, JavaScript/HTML5/CSS3, Sass/Less, Node.js, ReactJS, AngularJS, Vue.js, Cordova, Ionic, Android, design patterns, SOLID, databases (design, implementation, administration, both NoSQL and relational,..), deployment tools (Octopus, Jenkins,..), VCS, CI/CD, HTTP, networking, security (OAuth2, CORS, XSS, CSRF,..), algebra, algorithms, software testing, profiling, Linux, Unix, Windows, MS Office (advanced mail filtering,..), ITIL, IT Law (licensing and its implications when choosing a product, distribution right,..), server architecture,..
Sure yeah, I know, I've studied all that at university but.. it's been too long (almost a decade now). I have to revisit that knowledge.5 -
!dev (?)
Why does my teacher think it's reasonable to give an assignment for writing a scientific article about quantum computing in the first semester of CS? Like really? I just got out of fucking high school you bitch, all math I know is basic linear algebra. Thankfully I'm a nerd that likes computers so I got the basis of classical computing covered, I can only imagine how my classmates that never touched a computer are holding up.7 -
I remember back when I was in pre calculus I decided to take a class online. So my teacher's website was made by him and run on go Daddy, he taught precalculus, calculus, algebra, algebra ii, and computer science. I decided to penetration test his website and use a web crawler. His directory that had the tests, test answers, exams, exam answers, and homework answer's as well as all the books he's written in PDFs, was unprotected, I could access and download them all. He also had a database directory that contained all the students' phone numbers, email addresses, home addresses, and their full names.
I alerted him to this and didn't get anything in turn :P2 -
I was sitting in Geometry, and i realized something. Geometry fucking sucks, i would pick Algebra any day. I love using letters it reminds me of varibles and its not thay bad5

Applied Discrete Math is fucking hard. Logic and proofs are freaking hard. Even Multivariable calculus is piece of cake. Give me Calculus, Linear Algebra and I can get a high grade.
How do you even start to wrote proofs?
I’m in Chapter 2 and struggling. Imagine the later chapters.6 -
My fellow devs, appreciate what you have right now, even if it doesn't seem that great. I've recently switched majors from Bioinformatics to Medicine and I wouldn't say I regret it, but I do certainly doubt this decision sometimes. While studying Bioinformatics, I was always really interested in the biological part, often wanting to learn more about medical topics and such, thinking if I did switch, I could always keep programming as a hobby. Now I did switch and I miss being in a professional CS field so much. Medicine is great, but the people who study are mentally completely different from people that code. I still code small projects on the side, but don't really have anyone to talk to about them and I'm even starting to regret not paying more attention in linear algebra. I miss linear algebra, think about how ridiculous that is haha. Anyways, if you are looking forward to a major change in your life, it might not be all that you think it will be. So look at your current situation, it might be what you wanted all along.
Thanks for listening.

Also it is incredible, how technologically incompetent most medical students are lol4 -
My dad taught me basic algebra when I was a kid (I think 7-8). Then he taught me BASIC and within a month I decided I was going to be a game programmer when I grew up. Not quite where I ended up, but that's how the journey started.

Devrant help me out.
(n/x)*(y/x)
You know x, and you know n, and you know z where ((y/x)*x)*((x/y)*x) = z
Solve for y.
If you do it, I'll consider giving you a billion dollars (of course the payment schedule will be an asymptote).31 -
I am considering which CS elective to register for this coming semester, and I am not happy with many of the choices. Basically, I can choose between Android programming, a web programming class in the grad school, and maybe Linear Algebra for CS majors class. I am trying to figure out what is worthwhile to take in college, and what I can learn on my own. Advisor thinks I should take a web class, because it's important to know, but I am not too into web and I feel like I can just learn that on my own. I would rather take a class that will help me understand how things work, rather than just how to use a specific technology. What do you guys think?3

Any good programming language with great generics support that is not dynamic ?
Rust generics sucks so much I puked 2 times.
Tried with swift and it looks great.
Golang doesn’t have them.
Java sucks.
Maybe I try julia if someone say it’s cool.
I want to implement some 2d vector algebra and simple physics engine.
I started by creating generic 2d vector and trying to create dot product from it.
I didn’t wanted to do it in swift but wasted 2 days trying to do it in rust vs 1 hour in swift including 49 minutes of installing swift tools.
Anyway anyone know performant language with good generics support, let me know in comments.39 -
< The IT guy Fixes it all. A brief story about an old couple I knew >
So... I know a very old man, that keeps a great (young) appearence despite his over 80 yo. He has been a friend of my family also and my neighbour.
He lived with his slightly younger wife. They had suns/ daughters, grandsuns and even a few grand-grand suns. Despite their family keep making visits regularly, most of the time, their main company were the neighbours. And me and my younger brother were like a second grandsuns to them, and we saw them the same way.
Every time there was somethng to fix. A radio, a tv, an old ring telephone. They would call me to fix it.
At a certain age, my parents moved out to a different street, me and my brother started spending more time away from our village, so this very lovable cuple, keept calling to my place like we were still available 24/7.
The most funny request was when the old man calls meand says something like is:
OldMan: - Hello, André! everything is good with you?
Me: - Hi. I'm great! I'm spending a lot of time away now, but despite that, all is good.
OldMan - Nice to hear you! You are still studdying Computers? I think I need you to do me a favor, if you find some time.
Me - If it's nothing too difficult, or time consuming, maybe I can. What is it?
And then he breaks it.
OldMan - I have an electronic heater, but I can 't make it run. But maybe you can fix it. You know all about this electronic stuff...
(after laughing a litle bit)
Me : Well! That is a litle bit out of my league.
BTW. A curious info. The old women couldn't recognize a single letter before her 70's. She basically didn't knew how to use a phone, but then she started a senior class to learned to read, write and basic algebra. And this would become a life saving gift to her.
One time that she injuried herself in the back caused by an hard fall at her place, she was able to drag herself to the phone, and instead of calling the Urgence Team, she called me .
Luckly I was at home, and could get help in time.1 -
Any good linear algebra resources, preferably videos explained elegantly without much expectation of previous knowledge.5

Found my old project that deals with algebra in multithreading fashion
Just pushed it to github
Have a look at https://github.com/rational-kunal/... -
A && (B || C)
Is there any way to get rid of the parenthesis?
I know how to remove the OR but the parenthesis are still there:
A && !(!B && !C)18 -
If we can transform the search space or properties of a product into a graph problem
we could possibly use Kirchhoff's theorem to reveal products which are 'low complexity'
in particular search spaces, yeah?
Now according to
https://en.wikipedia.org/wiki/...
"n Cycle Space, A family of sets closed under the symmetric difference operation can be described algebraically as a vector space over the two-element finite field Z 2 {\displaystyle \mathbb {Z} _{2}} \mathbb{Z } _{2}.[4] This field has two elements, 0 and 1, and its addition and multiplication operations can be described as the familiar addition and multiplication of integers, taken modulo 2"
Wouldn't this relate to pollards algorithm, because it involves looking for factors of coprimes modulo N or am I mistaken?
Now, according to wikipedia, "in a group, the additive identity is the identity element of the group, is often denoted 0, and is unique."
If we make the multiplicative identity of our ring or field a tuple of the ratio of a/b for some product p, or a (and a/w, where w is the square root of p), or any other set such that n*m allows us to derive a or b, we could reduce the additive identity to the multiplicative identity, making the ring trivial. Solving for p would then mean finding a function from R to R, mapping every number to 0, i.e. finding the additive identity.
Now in a system with a multiplication operation the distributes over addition, the "additive
identity annihilates ring elements", so naturally, the function that maps to 0, gives us
our additive identity, we need only find the subset, no?
Forgive me if I'm wrong, but shouldn't this be convertible to a graph search?
I'm WAY out of my depth here so if anyone is familiar and can enlighten me I'd be grateful.
It's all unknown unknowns to me. -
Back then as teenager meddling around with QBasic I intuitively realized that you could instruct this machine to do whatever I want - now I could stick the Turing-Church-Hypothesis label to that notion, but I think the experience and feeling of that potential power of programming goes without abstract algebra.
The problem of course: What to do with it? First thing we programmed was a digital telephone book. A chess program? - That's still the thing with apps nowadays I suppose. What should it do? Steer a nuclear power plant or recognize cats on pictures?
(As I didn't know what to do with it back then, I turned to physics and mathematics only to get a job all the university stuff was pointless for but required the skills I taught myself as a 17 year old.) -
I'd like to learn about functional programming. What books, courses, tutorials or articles would you suggest? I have a good understanding of abstract algebra and I felt the need to learn it because my Typescript is a mess and I visibly don't know what I'm doing.1
