Search - "computer fundamental"
-
Lads, I will be real with you: some of you show absolute contempt to the actual academic study of the field.
In a previous rant from another ranter it was thrown up and about the question for finding a binary search implementation.
Asking a senior in the field of software engineering and computer science such question should be a simple answer, specifically depending on the type of job application in question. Specially if you are applying as a SENIOR.
I am tired of this strange self-learner mentality that those that have a degree or a deep grasp of these fundamental concepts are somewhat beneath you because you learned to push out a website using the New Boston tutorials on youtube. FOR every field THAT MATTERS a license or degree is hold in high regards.
"Oh I didn't go to school, shit is for suckers, but I learned how to chop people up and kinda fix it from some tutorials on youtube" <---- try that for a medical position.
"Nah it's cool, I can fix your breaks, learned how to do it by reading blogs on the internet" <--- maintenance shop
"Sure can write the controller processing code for that boing plane! Just got done with a low level tutorial on some websites! what can go wrong!"
(The same goes for military devices which in the past have actually killed mfkers in the U.S)
Just recently a series of people were sent to jail because of a bug in software. Industries NEED to make sure a mfker has aaaall of the bells and whistles needed for running and creating software.
During my masters degree, it fucking FASCINATED me how many mfkers were absolutely completely NEW to the concept of testing code, some of them with years in the field.
And I know what you are thinking "fuck you, I am fucking awesome" <--- I AM SURE YOU BLOODY WELL ARE but we live in a planet with billions of people and millions of them have fallen through the cracks into software related positions as well as complete degrees, the degree at LEAST has a SPECTACULAR barrier of entry during that intro to Algos and DS that a lot of bitches fail.
NOTE: NOT knowing the ABSTRACTIONS over the tools that we use WILL eventually bite you in the ASS because you do not fucking KNOW how these are implemented internally.
Why do you think compiler designers, kernel designers and embedded developers make the BANK they made? Because they don't know memory efficient ways of deploying a product with minimal overhead without proper data structures and algorithmic thinking? NOT EVERYTHING IS SHITTY WEB DEVELOPMENT
SO, if a mfker talks shit about a so called SENIOR for not knowing that the first mamase mamasa bloody simple as shit algorithm THROWN at you in the first 10 pages of an algo and ds book, then y'all should be offended at the mkfer saying that he is a SENIOR, because these SENIORS are the same mfkers that try to at one point in time teach other people.
These SENIORS are the same mfkers that left me a FUCKING HORRIBLE AND USELESS MESS OF SPAGHETTI CODE
Specially to most PHP developers (my main area) y'all would have been well motherfucking served in learning how not to forLoop the fuck out of tables consisting of over 50k interconnected records, WHAT THE FUCK
"LeaRniNG tHiS iS noT neeDed!!" yes IT fucking IS
being able to code a binary search (in that example) from scratch lets me know fucking EXACTLY how well your thought process is when facing a hard challenge, knowing the basemotherfucking case of a LinkedList will damn well make you understand WHAT is going on with your abstractions as to not fucking violate memory constraints, this-shit-is-important.
So, will your royal majesties at least for the sake of completeness look into a couple of very well made youtube or book tutorials concerning the topic?
You can code an entire website, fine as shit, you will get tested by my ass in terms of security and best practices, run these questions now, and it very motherfucking well be as efficient as I think it should be(I HIRE, NOT YOU, or your fucking blog posts concerning how much MY degree was not needed, oh and btw, MY degree is what made sure I was able to make SUCH decissions)
This will make a loooooooot of mfkers salty, don't worry, I will still accept you as an interview candidate, but if you think you are good enough without a degree, or better than me (has happened, told that to my face by a candidate) then get fucking ready to receive a question concerning: BASIC FUCKING COMPUTER SCIENCE TOPICS
* gays away into the night53 -
An excerpt from the best rant about whiteboard interviews posted on the internet. Ever.
"Well, maybe your maximum subsequence problem is a truly shitty interview problem. You are putting your interview candidate in a situation where their employment hinges on a trivia question. — Kadane's algorithm! They know it, or they don't. If they do, then congratulations, you just met an engineer that recently studied Kadane's algorithm.
Which any other reasonably competent programmer could do by reading Wikipedia.
And if they don't, well, that just proves how smart the interviewer is. At which point the interviewer will be sure to tell you how many people couldn't answer his trivially simple interview question.
Find a spanning tree across a graph where the edges have minimal weight. Maybe one programmer in ten thousand — and I’m being generous — has ever implemented this algorithm in production code. There are only a few highly specific vertical fields in the industry that have a use for it. Despite the fact that next to no one uses it, the question must be asked during job interviews, and you must write production-quality code without looking it up, because surely you know Kruskal’s algorithm; it’s trivial.
Question: why are manhole covers round? Answer: they’re not just round, if you live in London; they're triangular and rectangular and a bunch of other shapes. Why is your interview question broken? Why did you just crib an interview question without researching whether its internal assumption was correct? Do you think that “round manhole covers are easier to roll" is a good answer? Have you ever tried to roll an iron coin that weighs up to 300 pounds? Did you survive? Do you think that “manhole covers are circular so that they don’t fall into manholes” is a good answer? Do you know what a curve of constant width is? Do you know what a Reuleaux triangle is? Have you ever even been to London?
If the purpose of interviewing was to play stump the candidate, I’d just ask you questions from my area of specialization. “What are the windowing conditions which, during the lapping operation on a modified discrete cosine transform, guarantee that the resynthesis achieves perfect reconstruction?” The answer of course is the Princen-Bradley condition! Everyone knows that’s when your windowing function satisfies the conditions h(k)2+h(k+N)2=1 (the lapping regions of the window, squared, should sum to one) and h(k)=h(2N−1−k) (the window should be symmetric). That’s fundamental computer science. So obvious, even a child should know the answer to that one. It’s trivial. You embarrass your entire extended family with your galactic stupidity, which is so vast that its value can only be stored in a double, because a float has insufficient range:"

In `Computer Fundamental` class
friend: What 1 + 1 equal to?
me: two.
friend: ...no, it's equal to ten.
me: oh fuck!2 -
I can agree to shit when presented with hardcore data, data that proves me otherwise. But when people go by opinions and then hold is a truth because of "many feel the same way" I cannot help but to giggle a bit.
Most issues I have found with programming stacks come from opinions rather than hard presented data, if a bunch of people dislike a tool, but it delivers, I get to differ two things: (1) it is bad but it performs as needed, but it is bad because of design problems etc, (2) some dude made a post concerning why he things is bad and sheep mentality follows.
If technologies were without merit, then we would have all discarded C++ a long time ago cuz Linus disliked it, a powerful programmer indeed, but a FOCUSED one, meaning, one that deals with 1 domain (kernel development)
Do I care about what Linus things about web development? No, lol, he is a better kernel developer than I am, but I highly, grossly doubt that he knows enough about web development to give me something to think about.
all languages have faults, regardless of what point of view we look at them, but completely disregarding a tech stack because of shit that you saw some fucktard wrote about, benefits and otherwise, just seems....well...sheepish, there might very well be a tech stack out there that covers everything, to me it is a mixture of things, and I use them as I please and feel like, but this is because after years of learning I have read about quirks and pitfalls and how to avoid them. I would suggest you all do the same, by you all I mean those of high opinions that can't be deflected.
This field is far too wide and concentrated to go head and think about absolutes when even the fundamental mathematical theory concerning computer science is not absolute whatsoever, it is akin to magic, shit works, but it might not, the incantation might be right, but circuits and electricity have a way of telling us to go fuck ourselves, so do architectures, specifically ones based on physics.3 -
I'm studying Computer Science and Engineering in Uni.
People don't understand the most fundamental principles of programming at all. Variables and functions are like a foreign language to them.
I get that not everyone knows everything but if you decide to go to uni to study programming, and you have never programmed before. Are you really in the right place?17 -
I'm bored af working on crappy php56 legacy apps written by short sighted programmers, makes my life miserable, but the pay is pretty good for a remote job which is pretty rare in here. Meanwhile I'm interested on exploring fundamental stuff on computer science and experimenting new techs.
I'm thinking about doing a PhD but too afraid if I can't finish it or the future opportunity isn't good enough since I live in 3rd world country in southeast asia. Also it probably takes ±8 years to finish it including the preparation.
I have no question, but it would be great if you have some advice.1 -
I might create a coding course for people actually interested in learning how to program correctly (not Get Rich Quick Bootcamp style, not webapps, not magic Javascript incantations).
I have an idea on how to structure it but I worry it'll be too weird for most people to follow (starting from binary theory and then teaching machine code and then working upwards to C and beyond) explaining how a computer works along the way, showing the real errors with annotations explaining things, etc.
I've always wanted to teach in this format but I feel as though it's too.. idk, "useless" to most people? But I've never had a friend go through e.g. CodeAcademy and come out knowing how to actually make applications from start to finish without just hacking together random React components and hoping the frankenstein project works well enough.
The target demographic would be those either completely new to programming or just have a fundamental or web-centric preexisting knowledge, or maybe those who simply want to understand computers better.
Am I barking up a shitty tree?28 -
Hello and welcome, to a presentation in which I will tell you my thoughts on the shortcomings of modern day computers and programming practices.
Computers are based on a very fundamental and old idea, folders, and files, a file is basically a concrete amount of data, whereas a folder is a group of files, and it comes from the real life concept of files and folders, now it might be quite obvious already that using a concept invented in 1898 by a guy called Edwin G. Seibels, might not be the best way for computers to function in the year 2020, but alas, it is.
Unless of course, you step into the world of a programmer.
A programmer’s world is much different, they use this idea of a data structure, or in simpler terms, an object. An Object is just like what you would think of as an object in your head, something with different properties that you can think about in different ways, for example your mobile phone, it has a battery percentage, it has a screen size, it has free space available. Programmers use these data structures to analyse data very quickly, like finding all phones with a screen size bigger than a certain size for example.
The problem is that programmers still use files and folders to create the programs that use these objects.
Consider this example.
Let’s say you want to create a virtual version of a drink bottle, consider what properties it will have, colour, volume, height, width, depth, material, etc..
As a programmer, you can leverage programming features and change the properties of a drink bottle directly, if you wanted to change the colour, you just say, drink bottle “dot” colour, equals blue, or red.
But if the drink bottle was represented as a file, all the drink bottles data would be inside the one file, so you would have to open the whole file, find the line or section of the file that has the colour data of the drink bottle, and select it, highlight it, delete what’s there, and type in your new value.
One way to explain this better is to imagine a folder that now represents the drink bottle, imagine adding a new file into that folder that represents each property I described before, colour, volume, etc.., well now, you could just open that folder, find the file for colour, either by looking with your eyes or you could do a file search in the folder for a file called colour, open it, and edit the value inside. This way of editing objects is the one that more closely represents the way programmers and a program itself interacts with objects inside a running programming language.
But the thing is, programmers don’t use the folder/file way of creating objects and putting them into programs, because it would be too cumbersome, they just create 1 file for an object, or have lots of objects in a file, and create all the objects in 1 file, and then run the program which creates the objects, then when they stop the program, it deletes the objects. So there is no actual link between the object in a file and the object that the program creates by reading the data from that file, if you change the object in your program, it does not get saved to the file.
So programmers created databases to house these objects, but there is still a flaw in databases, they are hard to interface with, and mostly databases are just used to send data or retrieve data from, programmatically, you can’t really browse a database the way you can browse the files on your computer. You can, but database interfaces are not made to be easily navigated the way files and folders are.
As it stands, there is no way to store objects instead of files on your computer and interact with them in complex ways the way programmers can inside the programs they create.
If the idea of an object became standard the way a file and folder is standard, I think it would empower human’s a great deal to express things far more easily and fluidly than they can today.
Thanks for reading.8 -
Computer science vs software engineering?
Software engineering is all about people. You have to communicate with the business, realizing their needs, figuring out their processes, optimizing them, all this before the first line of code is written. Then, you have to manage your direct reports, and if you have none, write code with people in mind, people who will read it after you. As they say, code is for people, not for computers. Then, you have to improve the app listening to users, again, people.
I can’t assign a software engineer a role higher than middle if they’re bad with people.
If you wanna do cool stuff with computers and be a misanthrope, do computer science! It’s a very prestigious field where you are left alone with scary math and fundamental concepts. If you’re successful there, you’ll have a mad asocial scientist card, and no one will ever insist to you that people is important. They will just accept that they shouldn’t annoy you, and you are “allowed” to yell at them because you’re “special” and a “genius”. You can hate them 24/7.1 -
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** -
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.
