Search - "calculus"
Six months ago my girlfriend broke up with me...
BUT since then I've...
•Found the wonderful world of devRant
•Gotten back into electronics
•Taught myself PCB design
•Gotten back into programming
•Made a discord bot
•Started teaching myself calculus
•Began building an ai for said discord bot
•Designed a wireless mesh networking NIC for the TI84+CE
Sure I feel like shit most of the time but before I did anyway but I've been super productive and it feels kind of nice47
I'm a self-taught 19-year-old programmer. Coding since 10, dropped out of high-school and got fist job at 15.
In the the early days I was extremely passionate, learning SICP, Algorithms, doing Haskell, C/C++, Rust, Assembly, writing toy compilers/interpreters, tweaking Gentoo/Arch. Even got a lambda tattoo on my arm after learning lambda-calculus and church numerals.
My first job - a company which raised $100,000 on kickstarter. The CEO was a dumb millionaire hippie, who was bored with his money, so he wanted to run a company even though he had no idea what he was doing. He used to talk about how he build our product, even tho he had 0 technical knowledge whatsoever. He was on news a few times which was pretty cringeworthy. The company had only 1 programmer (other than me) who was pretty decent.
We shipped the project, but soon we burned through kickstart money and the sales dried off. Instead of trying to aquire customers (or abandoning the project), boss kept looking for investors, which kept us afloat for an extra year.
Eventually the money dried up, and instead of closing gates, boss decreased our paychecks without our knowledge. He also converted us from full-time employees to "contractors" (also without our knowledge) so he wouldn't have to pay taxes for us. My paycheck decreased by 40% by I still stayed.
One day, I was trying to burn a USB drive, and I did "dd of=/dev/sda" instead of sdb, therefore wiping out our development server. They asked me to stay at company, but I turned in my resignation letter the next day (my highest ever post on reddit was in /r/TIFU).
Next, I found a job at a "finance" company. $50k/year as a 18-year-old. CEO was a good-looking smooth-talker who made few million bucks talking old people into giving him their retirement money.
He claimed he changed his ways, and was now trying to help average folks save money. So far I've been here 8 month and I do not see that happening. He forces me to do sketchy shit, that clearly doesn't have clients best interests in mind.
I am the only developer, and I quickly became a back-end and front-end ninja.
I switched the company infrastructure from shitty drag+drop website builder, WordPress and shitty Excel macros into a beautiful custom-written python back-end.
Little did I know, this company doesn't need a real programmer. I don't have clear requirements, I get unrealistic deadlines, and boss is too busy to even communicate what he wants from me.
Eventually I sold my soul. I switched parts of it to WordPress, because I was not given enough time to write custom code properly.
For latest project, I switched from using custom React/Material/Sass to using drag+drop TypeForms for surveys.
I used to be an extremist FLOSS Richard Stallman fanboy, but eventually I traded my morals, dreams and ideals for a paycheck. Hey, $50k is not bad, so maybe I shouldn't be complaining? :(
I got addicted to pot for 2 years. Recently I've gotten arrested, and it is honestly one of the best things that ever happened to me. Before I got arrested, I did some freelancing for a mugshot website. In un-related news, my mugshot dissapeared.
I have been sober for 2 month now, and my brain is finally coming back.
I know average developer hits a wall at around $80k, and then you have to either move into management or have your own business.
After getting sober, I realized that money isn't going to make me happy, and I don't want to manage people. I'm an old-school neck-beard hacker. My true passion is mathematics and physics. I don't want to glue bullshit libraries together.
I want to write real code, trace kernel bugs, optimize compilers. Albeit, I was boring in the wrong generation.
I've started studying real analysis, brushing up differential equations, and now trying to tackle machine learning and Neural Networks, and understanding the juicy math behind gradient descent.
I don't know what my plan is for the future, but I'll figure it out as long as I have my brain. Maybe I will continue making shitty forms and collect paycheck, while studying mathematics. Maybe I will figure out something else.
But I can't just let my brain rot while chasing money and impressing dumb bosses. If I wait until I get rich to do things I love, my brain will be too far gone at that point. I can't just sell myself out. I'm coming back to my roots.
I still feel like after experiencing industry and pot, I'm a shittier developer than I was at age 15. But my passion is slowly coming back.
Any suggestions from wise ol' neckbeards on how to proceed?32
The problem with being a programmer...
I just broke up with a girl I've been seeing the past 2 months, that I was really into.
But in the end, it became a question of, either i'm with her, or I'm with my work.
I don't think that would happen with other professions, at least, not as easily.
I think, with other professions or projects, you tell someone "I need to work" and it's really fucking understood. "Ok, you need to work"
They understand it. If I was a lawyer.. I have a case. if I was a carpenter, I have a wall to build,
or a house. Etc. All understood things. Or physical things that can be seen.
But with programming, first of all, I work my own hours, I write software and then sell it. I do it all myself, I own my own business. I don't have normal hours like a job, but I do know my requirements, which is at LEAST 8 hours a day of solid, uninterrupted work.
If I had a "job" it would be like "gotta go to work" and that would be it.
But, because I work for myself, and because the things I build, aren't like something you physically see, nobody gets it.
My parents, as supportive as they are, will never understand how I just implemented a new design pattern and like, leveled up because of it.
They see software... buttons, and even then, when I try to explain what excites me, it's like trying to get a 3 year old interested in calculus.
How could they possibly understand the richness of what I do, how fulfilling it is
and how much I love it, when all they see
is me on a computer, clicking keys.
The same for this girl I dated.
The only place I feel where people understand,
Do you have any similar experiences to share?
Would love to hear it right now.39
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.30
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
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
A friend just asked if I could get him an internship at the place I work. He has no computer/programming background at all but how hard could developing be.
So I informed him my CS degree required at least 7 math courses lowest being calculus.
You need to know math!?!?
Yeah we're the one who writes the programs that actually does the math for everyone else9
I don't like stickers on my laptop because it clutters it up. But today I realized the importance of them.
A few months ago I was sitting at a coffee shop working on a paper and I noticed a guy with this cool sticker on a MacBook Pro: it had the integral symbol to the left of the Apple logo, and to the right of it a lowercase d and another Apple logo. It took me a few hours to realize what it meant, but I finally did and at that point I also guessed that not many people know what it is.
So I, as antisocial as I am, I finish up my work and before I leave I walk up to him and say hi. At this point I'm a senior in high school and I learn he's a junior in the same college I plan to attend. We talked a little before I had to leave and got to know each other somewhat.
After I leave I find him on Instagram and Facebook and friend him and such.
Recently I posted a picture saying I had recently joined the Apple Developer Team, and also recently reposted a memory on Facebook from 5 years ago that was a screen capture of an iPhone 4 simulator running iOS 5 showing off one of my first apps.
Then yesterday I get a message from the guy I met at the coffee shop asking for some help with an iOS project he's working on. We decide to meet today and I spend the entire morning showing him the basics of Swift, Xcode, Interface Builder, etc. I feel like I really helped him jumpstart his app and helped him understand the basics of different concepts.
If he didn't have that integral sticker on his laptop I would have never had this opportunity to finally share some iOS development experience.
For this I would like to thank my high school calculus teacher, with whom I spent many classes at Starbucks because I was an only student. I'd like to thank laptop stickers, and finally I would like to thank the coffee shop.
TL;DR: Said hi to a guy with an integral sticker on his laptop, a few months later he approaches me for help understanding iOS development.2
1. Decide to learn optimisation algorithms
2. Realise that you have forgotten calculus
3. Decide to learn from the beginning
4. Search for tutorials
5. Go through the introduction parts
6. You know that you can't complete
7. You watch other entertainment things on YouTube.
Stories of a lazy programmer...12
This guy was the worst. We already knew each other because he taught me calculus at university. He hated me for no reason and he failed me for fun I think. Next semester I got an A with a different lecturer. So after 2 years he got hired as a project manager at the first company I worked at and he was bullying me there so he continued where he left off. I quit so the situation got resolved but that guy was the worst.6
Sorry guys, I know this is devRant and probably not a place to post this but am fucking burning with fury and fatigue! I should probably develop elecRant and post it there instead.
I FUCKING HATE POWER ELECTRONICS!!
I am in my final year of electrical engineering and I can fucking say with confidence that power electronics is the most fucked up unit I have seen in my life. A whole load of useless math from simple RLC circuits just to make students' lives miserable. For those who might not know, power electronics is some unit that involves use of solid state electronics(transistors, diodes etc) for power applications(switching mostly). Basically things like inverters and converters. UPS systems are an example of their applications.
Now don't be fooled by how that sounds cool and so smart, this shit is fucked up. These circuits in the attached picture might just seem like simple RLC networks with some BJTs, but they are devils in their own right. They fucking need some advanced unnecessary calculus and Fourier analysis to even calculate the simplest output current!! Worst still, some of these motherfuckers have more than 1 mode of operation,needing one to analyze some fucking 100+ waveforms. I fucking hate this shiit! I hate it!
You might say that i am just being lazy and don't want to study. Let me tell you something, FUCK YOU TOO!!20
I can code better then most CS students, but if I want to go to university I have to take things like calculus... why65
Rant about a german problem in english
I think we as the people should just sue the german government for neglect of progress and neglect of the education system. If your not familiar with the state of german IT we have worse internetspeeds than uganda or the notoriously shitty australia, our neighbourstates look at us in disbelief while laughing in optic fibre. Our school system seperates all students after 4th grade in 3 tiers, the lowest one gives you the future perspective as a social security case. The second and highest tier require masses of useless knowledge, so called "competences"(Kompetenzen) which are totally useless skills with no real world application because they are derived from real skills, a median ground between all possible applications of that skill. And while doing that they terribly insist on doing everything the "proper" way, meaning handwritten. Most people you would expect to have basic computer literacy, meaning age 40 and below, are incapable of using basic functions of a non-smartphone computer and do not understand the slightest of what they are actually doing or supposed to do. And I mean nothing technical. Germans are the reasons they still put word as a job requirement for devjobs because this disqualifies half of our population. This leads to many people having the archaeic "we versus the machines" mentality, thinking that if they ever let the computer do parts of the job, they will then lose all of it to the machines. Thats why you never strive past basic mathematical principles in mathematics, which is a big misnomer because you never do actual mathematics, only calculating and basic calculus and statics. If you get to use your calculator, its some basic casio with no actual functionality then standard operations. And even using that is shunned upon. How is this country ever supposed to become something more than it was in the 90's, if we teach people nothing of use and kill all progress in its root.22
Does anyone else ever feel like they're too stupid to be a good programmer? Like some of the people here are very very intelligent. Meanwhile, I'm over here making a fucking 8% on a calculus exam. I just feel like I'm way too stupid to actually be good at this.19
Snippet of an overheard conversation today:
"LOL maths beyond basic arithmetic is so dumb. No-one needs pythagoras, trig, calculus or any of that crap unless they have some unholy desire to find the geometric properties of their sandwich."
"What do you want to do when you leave school then?"
"Something to do with AI. That stuff is really cool."
When I was 17 years old. I had difficulties in understanding math problem “Calculus” (I can’t remember which one was it). This one day when we were in a Computer Lab, our teacher was showing us how really software’s are made. During my time, it was vb6. I paid close attention. When I went home, I started to think things that I can make using that software so one day I went to my teacher and asked if I can have a copy of the vb6. He gave vb6 and told me that inside are few eBooks that will help in learning.
Fuck School, from that day I started to concentrate on programming only. Made a small calculator which will help me to understand a Calculus problem and double check my answer. From that day, I love programming.
I’ m 26 now and a full stack software developer. All I want to do it build cool shit, something that will blow the eyeball of my friends and that eyeball should pop out from their asshole.
Joke: The person who scored highest in the computer class was afraid to switch on the PC.1
1. Learn Kotlin
2. Actually sit down and push through machine learning.
3. Finish integral calculus and start multivariable calc.
4. Work on 1 project until completion.
5. Socialize a bit more.
6. Obliterate bugs.5
I have finals next week. I am sitting here learning about things which have no benefit to my career. My college requires me to take Calculus based physics 2, which makes no sense to me at all! I do appreciate physics however I would much rather be coding. In my CS courses you learn theory which is fine, however very impractical. I last October I realized how much more you need to do and a degree just won't cut it. I spend about 50 hours a week learning TDD, git, hashes all this stuff that is not taught in school. Then on top of this I'm learning pointless crap that if I ever needed in a real world situation I would go to Kahn Academy or simply Google it. I'm upset because I have to stop coding for the week to study information I will forget 2 weeks from now, and most likely never use again. I have a job someone offered me which will be extremely beneficial to my career however I have to wait a week to even look at it. I'm just bitter.21
I don’t like to judge people based on what languages they like (because I like all of them). But I can’t deny the pattern anymore.
You, my friend, are not one of those people. You are VSCode-dwelling goblin who thinks lambda calculus has something to do with JS arrow function notation, is scared of reduce() and not even good at the single fucking language they know.
Insta coders and that mechanical keyboard collector dorks are not “superstars” you got to be like.11
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.
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.
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
I wish I had this guy as my calculus teacher in college. It was hell understanding the concepts because of language barriers.6
It took us 30 years to get to the point where phones and laptops use the same charger but at least we are here. Also fuck calculus.15
There are a couple of them to list! But to sum my main ones(biggest personal heroes):
John McCarthy, one of the founding fathers of Artificial Intelligence and accredited with coining such term(sometimes before 1960 if memory serves right), a mathematical prodigy, the man based the original model of the Lisp programming language in lambda calculus. Many modern concepts that we have in programming where implemented in one way or another from his systems back in the day, and as a data analyst and ML nut.....well I am a big fan.
Herb Sutter: C++ programmer extraordinaire. I appreciate him more for his lectures and published articles than anything else. Incredibly smart and down to earth and manages to make C++ less intimidating while still approaching it with respect.
Rich Hickey: The mastermind behind Clojure, the Lisp dialect for the JVM. Rich is really talented and his lectures behind his motivations and reasons behind everything he does with Clojure are fascinating to see.
Ryan Dahl: Awww shit y'all know how it is. The man changed web development both in the backend and the frontend for good. The concept of people writing their own servers to run their pages was not new, but the Node JS runtime environment made it more widely available to people by means of a simple to use language that was already popular with web developers. I would venture to say that Ryan's amazing contributions to JS made the language better, as it stands, the language continues to evolve and new features that make it overall better keep being added. He is currently building Deno, which would be a runtime environment for TypeScript, in Rust.
Anders Hejlsberg: This dude was everywhere man....the original author of Turbo Pascal and the lead of Delphi back in the day. These RAD tools paved the way for what would be a revolution in the computing world. The dude is also the lead architect and designer of the C# programming language as well as TypeScript.
This fucker is everywhere and I love it.
Yukihiro "Matz" Matsumoto: Matsumoto san is the creator of the Ruby programming language. Not only am I a die hard fan of Ruby, but of the core philosophies that the man keeps as the core of his language design: Make the developer happy, principle of least surprise. Also I follow: minswan which is a term made by the Ruby community that states Mats is nice so we are nice. <---- because being cool to others is better than being a passive aggressive cunt.
Steve Wozniak: I feel as if the man does not get enough recognition...the man designed the Apple || computer which (regardless of how much most of y'all bitch and whine) paved the way for modern micro computers. Dude is also accredited with designing one of the first programmable universal remotes(which momma said was shitty) but he did none the less.
Alan Kay: Developed Smalltalk and the original OOP way of doing things. Smalltalk as a concept is really fucking interesting. If you guys ever get the chance, play with Pharo, which is a modern Smalltalk. The thing is really interesting and the overall idea of Smalltalk can be grasped in very little time. It sucks because the software scales beautifully in terms of project building, the idea of hoisting a program as its own runtime environment and ide by preserving state through images is just mind blowing to me. Makes file based programs feel....well....quaint.
Those are some of the biggest dudes for me. I know that the list is large, but I wanted to give credit to the people that inspired me the most. Honorary mention goes to other language creators and engineers of course, but it would be way too large to list!9
I think I like teaching.
Today I was helping out a friend with an algorithm for an assignment because he had no idea how to do it (we're on the second semester). You could see that we was completely lost, without a clue on what to do. So I showed him how to think about programming, how to figure out the problem and the solution before going to the code. I was so goddam happy when I saw he understood it. At the start I was guiding him heavily, but towards the end I'd just loosely describe what he had to do (and, of course, explain why) and he'd know how to do it. It just made me so fucking happy and so fucking proud of him, I was dancing on my chair, you guys have no idea. He went from 0 to 60 in 2 hours, I could teach him what the teacher couldn't.
I college I'm kinda explaining a lot of stuff (mostly programming and calculus) to my friends, even to classmates I don't know (I made a few friends this way) and I fucking love it. Seeing people completely lost, shining a light on them and seeing them fly, it's fucking awesome. Idk it's just very fulfilling.
Not sure I'd like all other responsibilities that come with being a teacher, but teaching in of itself is **g r e a t**, definitely a career path I'm considering.
Today was a good day :)14
The first time I took Andrew Ng's Machine learning course in 2014.
I was blown out of my wits at what could be achieved with simple algebra and calculus.1
Sorry but I'm really, really angry about this.
I'm an undergrad student in the United States at a small state college. My CS department is kinda small but most of the professors are very passionate about not only CS but education and being caring mentors. All except for one.
Dr. John (fake name, of course) did not study in the US. Most professors in my department didn't. But this man is a complete and utter a****le. His first semester teaching was my first semester at the school. I knew more about basic programming than he did. There were more than one occasion where I went "prof, I was taught that x was actually x because x. Is that wrong?" knowing that what I was posing was actually the right answer. Googled to verify first. He said that my old teachings were all wrong and that everything he said was the correct information. I called BS on that, waited until after class to be polite, and showed him that I was actually correct. Denied it.
His accent was also really problematic. I'm not one of those people who feel that a good teacher needs a native accent by any standard (literally only 1 prof in the whole department doesn't), but his English was *awful*. He couldn't lecture for his life and me, a straight A student in high school, was almost bored to sleep on more than one occasion. Several others actually did fall asleep. This... wasn't a good first impression.
It got worse. Much, much worse.
I got away with not having John for another semester before the bees were buzzing again. Operating systems was the second most poorly taught class I've ever been in. Dr John hadn't gotten any better. He'd gotten worse. In my first semester he was still receptive when you asked for help, was polite about explaining things, and was generally a decent guy. This didn't last. In operating systems, his replies to people asking for help became slightly more hostile. He wouldn't answer questions with much useful information and started saying "it's in chapter x of the textbook, go take a look". I mean, sure, I can read the textbook again and many of us did, but the textbook became a default answer to everything. Sometimes it wasn't worth asking. His homework assignments because more and more confusing, irrelavent to the course material, or just downright strange. We weren't allowed to use muxes. Only semaphores? It just didn't make much sense since we didn't need multiple threads in a critical zone at any time. Lastly for that class, the lectures were absolutely useless. I understood the material more if I didn't pay attention at all and taught myself what I needed to know. Usually the class was nothing more than doing other coursework, and I wasn't alone on this. It was the general consensus. I was so happy to be done with prof John.
Until AI was listed as taught by "staff", I rolled the dice, and it came up snake eyes.
AI was the worst course I've ever been in. Our first project was converting old python 2 code to 3 and replicating the solution the professor wanted. I, no matter how much debugging I did, could never get his answer. Thankfully, he had been lazy and just grabbed some code off stack overflow from an old commit, the output and test data from the repo, and said it was an assignment. Me, being the sneaky piece of garbage I am, knew that py2to3 was a thing, and used that for most of the conversion. Then the edits we needed to make came into play for the assignment, but it wasn't all that bad. Just some CSP and backtracking. Until I couldn't replicate the answer at all. I tried over and over and *over*, trying to figure out what I was doing wrong and could find Nothing. Eventually I smartened up, found the source on github, and copy pasted the solution. And... it matched mine? Now I was seriously confused, so I ran the test data on the official solution code from github. Well what do you know? My solution is right.
So now what? Well I went on a scavenger hunt to determine why. Turns out it was a shift in the way streaming happens for some data structures in py2 vs py3, and he never tested the code. He refused to accept my answer, so I made a lovely document proving I was right using the repo. Got a 100. lol.
Lectures were just plain useless. He asked us to solve multivar calculus problems that no one had seen and of course no one did it. He wasted 2 months on MDP. I'd continue but I'm running out of characters.
And now for the kicker. He becomes an a**hole, telling my friends doing research that they are terrible programmers, will never get anywhere doing this, etc. People were *crying* and the guy kept hammering the nail deeper for code that was honestly very good because "his was better". He treats women like delicate objects and its disgusting. YOU MADE MY FRIEND CRY, GAVE HER A BOX OF TISSUES, AND THEN JUST CONTINUED.
Want to know why we have issues with women in CS? People like this a****le. Don't be prof John. Encourage, inspire, and don't suck. I hope he's fired for discrimination.12
CAN SOMEONE PLEASE EXPLAIN TO ME WHAT THE FUCK LAMBDA CALCULUS IS??!?!?!
I swear to fuck, nothing makes you feel more like an idiot than trying to understand functional programming after living all your life in the oop world.
Fucking meta-functions and alligator games.
Fuck this, I'm going back to my happy little Java world11
This is real rant, not one of these funny stories!
So, I spent 4 years to get a Computer Science degree, and did two specializations, 3.5 years more in Uni. I have 6 years of experience working in IT, from support to programming. I also speak 3 languages.
I'm from a South America country, and now I'm living in EU.
I'm 30 now and earning a little more than a MacDonald's cashier earns in the US. I have to live in a shared apartment like a fucking Uni student. I have nothing, no car, no house, no girlfriend. WTF!
IT is a fucking lie! Profession of the future my ass!
In Uni they said that finding a good job was easy, that companies would literally grab us by the neck to work for them. LIE!
I did found a low paying job though, where at least I could learn a lot more.
People were really satisfied with my work and I even received a proposal of one of our clients to work for them, but the offer wasn't good enough.
I tried entering some big companies as a Trainee, but it was so ridiculous, they said they were looking for an IT person, but they asked things related to economy and other stuff that had nothing to do with IT. I always failed in the group work/interview, it was so ridiculous, I remember one candidate saying her dream was to work for the company since she was a child, SERIOUSLY!
When the opportunity came, I moved to EU and now I'm working as a dev. But as I said, I'm not satisfied with it! In the US the yearly average software engineer salary is about 100K, I earn less than 1/4 of it. And don't come saying that US pays more because of the cost of life, here the cost of life is the same or even more expensive, a super small apartment/loft is at least 180K, a simple new car 18K and a Big Mac costs 4€.
In the US, the average salary of someone that just graduated from uni is 60K to 70K! LOL
In EU, it's super hard for someone to earn 100K, that's why many companies are creating offices here, good workforce, 2 to 3 times smaller salary!
IT also sucks because it's too volatile, there's new stuff all the time. Someone always has to come with a new language, new framework, new library, etc etc. And you have to keep learning new stuff all the time.
Also job openings always ask for experienced people, like you must have at least two years of experience with VUE.js, or something.
Do you remember the last time you went to a doctor for a checkup, did they use a new tool, or did something different during the checkup? Probably not, the medic don't have to learn new stuff all the time, he is still using a stethoscope, he is still placing a wooden stick in your mouth to check your throat...
But in IT, almost no one nowadays is going to create code using CoffeeScript, they instead will use TypeScript.
I read an article saying that an IT professional must study 20 hours a week to keep up with new trends. So I must work 40 hours and study another 20? LOL
It's not that I don't like learning new stuff, but this sucks, I want to maybe learn something different or have a hobby.
Today I regret going to uni, I feel it was a waste of time and money. They taught things like calculus and physics that I never had to use professionally, and even programming stuff like linked lists I never had to use.
If instead I had studied dentistry or studied to be a ophthalmologist I think I would be earning more, would be working more independently and wouldn't need to keep up learning new things so much.
Also to work in IT you don't need a diploma, I read an article by a dude that learned programming by his own, did some software for his portfolio and got a job at Google.
When I read these kinds of story I regret even more going to uni, It really feels I wasted my time.
For these reasons I can't recommend going to uni to study IT, if you want to go to uni go study something else!
If you want to study programming do it on your own, there's everything you must know online for free, create a portfolio, and look for a job or even try working for yourself!
Living the life I have now, there's just no incentive to keep going.
Should I keep learning new stuff so maybe I can get a better job that will still pay low, or quit and try creating something on my own?
Or even ditch IT all together and go back to uni? LOL NO!7
I believe it is really useful because all of the elements of discipline and perseverance that are required to be effective in the workforce will be tested in one way or another by a higher learning institution. Getting my degree made me little more tolerant of other people and the idea of working with others, it also exposed me to a lot of topics that I was otherwise uninterested and ended up loving. For example, prior to going into uni I was a firm believer that I could and was going to learn all regarding web dev by maaaaaself without the need of a school. I wasn't wrong. And most of you wouldn't be wrong. Buuuuuut what I didn't know is how interesting compiler design was, how systems level development was etc etc. School exposed me to many topics that would have taken me time to get to them otherwise and not just on CS, but on many other fields.
I honestly believe that deciding to NOT go to school and perpetuating the idea that school is not needed in the field of software development ultimately harms our field by making it look like a trade.
Pffft you don't need to pay Johnny his $50dllrs an hour rate! They don't need school to learn that shit! Anyone can do it give him 9.50 and call it a day!<------- that is shit i have heard before.
I also believe that it is funny that people tend to believe that the idea of self learning will put you above and beyond a graduate as if the notion of self learning was sort of a mutually exclusive deal. I mean, congrats on learning about if statements man! I had to spend time out of class self learning discrete math and relearning everything regarding calculus and literally every math topic under the sun(my CS degree was very math oriented) while simultaneously applying those concepts in mathematica, r, python ,Java and cpp as well as making sure our shit lil OS emulation(in C why thank you) worked! Oh and what's that? We have that for next week?
Mind you, I did this while I was already being employed as a web and mobile developer.
Which btw, make sure you don't go to a shit school. ;) it does help in regards to learning the goood shit.7
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
For robotics I decided to write a program that would automatically tune a PID loop (a loop with three magic constants that tells you how much power to give the motors).
Being a high school student who hasn't been taught anything about the theory of PID loops or the right way to tune them, I had no clue what I was doing. So instead of actually learning the calculus to do it, I just made an evolutionary tuner that keeps guessing slight variations of the last-best three constants.
Basically, you press start and the robot spins in circles until you come back in 15 minutes.3
I was working yesterday, writing a calculus with sql.
My very great user explained to me the math in Excel. I first though to myself, piece of cake, i got it.
Then I started typing and at the end of the day i had 6 temp tables which at some point need to join with themselves. It was just hilarious. each table had at least 4 millions rows.
Then I started a new query just for validating the output of me very ugly previous queries.
And I fucking found a easier way to get the same output with 3 joins of 3 different tables and a count at the end.
When you love yourself. but hate yourself at the same time.
xD it was a very productive Friday night2
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.
10/10 would kaggle again2
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
College is rapidly sending me into a never-ending spiral of depression. I have to take Calculus-based physics for Computer Science, and it's making me want to kill myself. I'm not going to get anything higher than a D in it, so I'm going to have to take it again no matter what. I'm worried I'm not going to get a D in it because if I don't get at least a D in it, I won't be able to take the second part of it in the spring, which will remove 5 credit hours from my schedule that I will then have to find something else to fill with.
Worried that the terrible Physics grade I'm going to get is going to drop my GPA below the requirement for my scholarship. Worried that I'm going to get kicked out of the honors program as well. Worried that I'm going to be here for three more years. (My scholarship runs out in Spring 2020.) Stressing out about my Physics final tomorrow that will determine whether I pass or fail the class.
Im starting to wonder if that Computer Science degree is worth it.4
Back in grammar school we started programming in TI-Basic on a TI89 Titanium as it was part of math class (calculus and geometry). I didn't really understand much because the teacher thought it was a great idea to start with recursively calculating GCD (and we were in a sort of "linguist profile", nobody had ever touched a line of code in their lives before). I still liked it though and by some coincidence I got an old Win95 compaq notebook to play with from a friend.
I started playing around with the CMD prompt and batch files and could apply some of the things I had learned on the TI, like GOTO or If statements. I still didn't know what I was doing of course, and so it happened that I used the > file pipe when trying to compare two values. Suddenly there was a file with some code fragments and I started to get what I had done. I put the file pipe into an endless GOTO loop and was amused how those few lines filled up the whole desktop with nonsense files. I went on to refine this a little so I could control it with another file that acted as a kill switch when present. Over the next weeks I played some more with it and made it write out and start another batch file that would check whether the original script was still there and recreate it if not.
That notebook was so large and heavy I could not bring it to school, so I wrote all code by hand on paper and typed it in when I got home, that way I could still code in class when I was bored and no one would notice.
So my first ever "program" that I wrote myself was some lousy malware.5
If you saw my last rant, you'll know how much I hate Calculus. I decided instead of trying to learn this foreign topic, I'd instead translate it into a language I DO understand: C. The irony is that we use Calculus so we can learn to code easier, but I'm using code to learn Calculus easier. Funny if you ask me.1
I think I need some "programming detox", a couple weeks away from any kind of software development. It's just not fun anymore, I have lost my drive, I'm lazy to learn new stuff, I never finish my projects, I don't even know if I enjoy web development anymore.
Actually, I'm kind of lost on what to do with my life.
I don't want to become a full time web developer because it's boring, it's always the same shit: write frontend with some sort of framework, design database, write backend, rinse and repeat. There's nothing new, all projects seem to have the same requirements.
I don't want to get into machine learning and whatnot because it's a lot of math and theory, I like math but idk if I would like doing that all day. Same goes for basically anything related to research.
Low level stuff: on paper I like it, it's interesting, but I'm too lazy to learn and whenever I come up with a robotics project I end up making a shopping list and forgetting about it because either 1) stuff is too expensive or 2) I can't make the parts I want without spending a lot of money on tools. Also from what I can see in school, VHDL is boring af.
I just don't know what I like anymore, nothing gets me excited, not even video games. I used to like csgo but I just suck at it and I only play it because there's nothing else to play and deep down I still have a little bit of hope of becoming a decent player, even though I know I never will.
I just don't know what I want out of life. Sometimes I just like having tons of school assignments (especially calculus ones) just to keep me busy.8
So out of curiosity, does anyone here with a computer science degree actually use any of the non-programming classes you had to take for your degree?
All those damn hours studying calculus and discrete math (ugh, I hated induction).. Not to mention biology, organic chem, history... Ugh11
Student: I f*cking hate this calculus I am not even good in math.
Professor: Then why did you choose Computer Engineering it needs a lot of math.
Student: Because I love computer.
I’m living the dream. Lightweight, powerful, beautiful gaming laptops are a thing (have been for a while) and I have the pleasure of owning one.
I remember one of my college peers having a BRICK Alienware laptop in 2010. Don’t get me wrong, It was awesome at the time and I was super jealous, but it was insanely loud, heavy af, and as thick as a calculus textbook!
But now with the amazing RTX GPUs, and TB SSDs I can game on max settings, benchmark fairly well and take it with me when I travel for work alongside my work laptop all in the same bag without breaking my back.
🤘🏼 I love my Asus Zephyrus 🤘🏼
The fan is still hella loud though 😆
Maybe by mid or late 2020s we will have a revolutionary cooling system that would rid our dependence on fans for cooling. Just dreaming out loud here. It sure would be great to not have to clean the dust out.9
What paradoxes taught me.
Perhaps each time a paradox is encountered in mathematics, there is a useful distinction or mathematical tool hiding in plain sight, one that hasn't be discovered or utilized. For cursory evidence I give you: division by zero, the speed of an arrow at any point in flight, and calculus.
Maybe this isn't true for some paradoxes, or even most, but as time goes on I suspect people will discover it is more true than they might have thought.
Undefined behavior and results aren't nonsense: They look to me like golden seams to be explored for possible utility when approached from uncommon angles with uncommon problems.6
Guys I'm very bad at staying focused on one thing.
For a bit, I've been learning web development, and I've been working on a page for myself. Past few days I haven't really done anything because I'm trying to actually fucking graduate high school and as of right now I am NOT graduating.
But today I was taking my calculus final and I ended up talking to the teacher for a bit. He said he has an older tablet that he's trying to turn into a type of wall mounted home automation system. I believe he said something about using essentially a minimal Linux install to do it.
That really got me thinking, because I had a fairly similar idea a while ago (not exactly home automation, but just using an old tablet as a small Linux device), but never put in any actual effort to get it done. Now with winter break coming up for me, I really want to try and work on it some.
So before I start doing a fuckton of research on this, has anyone here ever done something similar to an Android device? I'm not talking about using that Linux Deploy app or a chroot. I'm talking about basically removing the Android environment, taking it down to a base Linux install. I just want to know if anyone can steer me in the right direction to save me some time3
Calculus sucks. My proffessor is good, but I have no idea how to Differentiate functions.
My CoSc class is much funner7
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.
**drops your mom's fatass...i mean mic**
I just failed the same maths module for the second time
At this point after working really hard and even getting a private tutor I really think I'm not cut out for this shit.I just don't know what to do right now.6
I'm in the middle of my exams.
My thoughts go - Work! Keep the fucking As up!
My actions - setting up public dotfiles with more comments than config lines, messing with DevRant, doing pre-calculus (matrixes, complex number shit) from 9th grade
Then had the English exam and realised that I'm fucked.
But now it's a Friday!
... And I have 3 major exams next week. I NEED to study for them.
I can already guess what I'm going to be doing during exam study time.
So you know when you write an exam.You studied your ass off every day for the last 4 weeks .You see the questions and you like hey I can do like 80-90% stuff.You do the paper.You smile while handing it in
Then,you wait.Confidently.In your mind thinking "hey don't fear the maths calculus paper was nice"
You recieve your marks after 2 weeks
You check it,and your heart COMPLETELY SINKS.How on living earth did I get 40%
Idk what it might be, insufficient studying(maybe revising the syllabus three damn times in 4 weeks wasn't enough).or stupid mistakes.or just the fact that it maths(calculus).This is the mid year so this mark doesn't determine if I pass or fail.
I need help,like serious help.I've kind of lost hope right now.If I talk to my parents their only solution is to study more(which clearly isn't doing the trick for the past 3 years in the same course)
I don't know anymore.I just dont.5
@11.30 pm -->BF: "Comm'on now...what Ya still doing there..aren t Ya comeing??? O.o already..."
ME: "Soon hun, i m learning some snake handeling here..hold on now!"
BF: "Yeeahp..Ya are handeling it all right already, you need to put it in the practice too. Come now. !" <<<--grinns.
ME: <<--lifting my glasses up to my head slowly: " I am writing...handwriting...the code!! Python!...?"
BF: "Yeah, i know...i saw yar test -B+.
If ya had done the finances calculus program for our maintance..my building checks, our food, your clothes...you would have more practice to put it into use...and you would have got an A probably..." He s freaking smirks and i went
qwaaak qwaaak qwaak- squachhh
I am so putting it into Rant )
..and i am so keeping him...
I'm starting senior year and I had to give up the independent study computer science class for BC calculus (my teachers convinced me BC is better in the long run) and instead I'm gonna be a teacher aid for the computer science teacher :/ I looked forward to IS since freshmen year and it sucks I had to pick and choose 😭 there's always scheduling conflicts at my school..2
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'm a CS student, and I'm having serious doubts. I love programming and my job on campus has me making a .net site and such which I enjoy.
However, I'm doing really bad in calculus again, and if I fail it I may never get to retake it because it's my third try. I know I can get a job without a degree, but I'm unsure if I even want to program anything that would require knowledge of calculus anyway. I understand what it accomplishes, but I don't want spend the rest of my life applying calculus. Is it really that important in industry? Or is it just something college puts an undue pressure on?
My CS courses don't challenge me much, and I enjoy them a little, but is being great at calculus required?5
For the love of God, I cannot find the motivation to learn calculus. I'm like 1-2 weeks behind schedule on it and the teacher is probably gonna start giving out assignments soon, but I can't sit down and fucking study. It's not that I don't like math, I just don't like studying. The only way I study is when I'm pressured by an assignment/test deadline, that's how I always did it, but now I'm in college. I'm not studying just to get a passing grade, I need a fucking A and, above all, I need to learn the damn thing. But I can't find the patience to study without the threat of getting a low grade, so I let everything accumulate and then learn everything in a day or two, just enough to get a B+ or something like that. I'm hating myself for that, and I have to fix it asap. I guess I'll try studying again tomorrow...9
Senior year of highschool (5 years ago), my friend and I were bored in Calculus class. The calculators we used were the TI-NSpire CX cas (the most advanced Texas Instruments graphing calculator at that time). After figuring out we could get a Game Boy Advance emulatir on the calculator, we decided we should try making out own game for it. That was when I figured out what I wanted to do with my life and havent looked back yet
For those who graduated, how the heck do you people do it? I'm on the verge of failing and/or having to retake Calculus AGAIN! I thought that if I could retake it, I would do better. But nope, now instead of getting into that really good tech school in a couple years, I'm a fledgling developer stuck in commonunity college with a 2.9 GPA and not a single project finished. Every decision I make has an exponential affect on my future, but right now, I got nothing. I can't see myself going anywhere else or doing anything else than software development. I'm not quitting, but that isn't enough anymore. This is a nightmare.3
My time management skills are abysmal. I am in my senior year in school and a few months back decided to appear for the informatics Olympiad. So now I am reading a book on discrete math, while reading books on algorithms and data structures. I code every day for around two hours. I have my math syllabi in school which is all calculus. My physics syllabi consists of all of EM and Optics along with nuclear physics. I haven’t touched chemistry since the beginning of this year. I try to give a considerable amount of time to math and physics because I f***ing love studying those. But doing that means slacking off on the Olympiad stuff. I am completely overwhelmed. My midterms are two weeks away and I am so unprepared. I am really clueless on how to manage time.
ProjectEuler problem difficulty level increases logarithmically after question 50. Question 60+ seems to take 10 times longer to solve than previous 50. I give up solving questions to write code to run within within 1 minute (which is a general rule specified).
I need to relearn Calculous...2
Think of an awesome sounding AI project while not knowing a thing about AI.
Tell the guy you will be working with that you will manage to keep the learning pace up (he doesn't know AI as well, woah!)
Fast forward 2 weeks - completely forget about how I wanted to do anything with AI.
Fast forward 1 week - that guy messages me that we ought to do a meeting to check how much each of us have learned and to decide on how we will tackle the project.
Somehow managed to get the deadline to be day after tomorrow.
'I am screwed...' is what I think when I skim through pages of 'Artificial Intelligence a Modern Approach'. So, I put down the book and try to find something easy to understand on youtube. I find a hyperactive looking guy that under a video titled along the lines of '5mins and you are linear gradient pro'. Not suscipious at all.
Watched video twice, managed to understand that I need calculus for this shit. Oh well.
AI seems so much fun until you understand that it requires a fuckload of knowledge to do anything at all! :'(
Going to try to analyse linear gradient until tomorrow and hope that it will be sufficient for our project.
Lol. Who am I kidding?
So will https://projecteuler.net help me in solving and interpreting mathematical problems better?especially in term of calculus
I was in junior college working on a mechanical engineering degree taking Calculus 1, some other classes, and a beginner level C programming class.
I decided being a ME wasn't for me as I couldn't handle the math, but the programming was a lot of fun. I ended up dropping Cal 1 and changing majors only to find out that I needed to transfer to a 4 year school to continue on the developer track. A few years later in December of 2013 I graduated with my BS in Computer Information Systems and a couple of years after that I had a great job as a dev.
Just finished my finals.
Had to run k-means with pen and paper only. I find this kind of question stupid but why not. BUT WHY THE FUCK DID YOU CHOSE SOME INITIALIZATION THAT TAKES 13(!!!!) FUCKING ITERATIONS TO CONVERGE ? Just in case my first 12 iterations are correct by chance ? Guess what, you fucktard, I GOT IT.
And doing the same calculus by hand 13 FUCKING TIMES is moronic as hell, you retarded piece of shit ! When you train your neural networks, do you also backpropagate your gradient all by yourself, mongoloid baboon? Getting sick of those stupid assignements1
I spend way too much time here, on my Calculus class. Rants > math.
I should uninstall this app so I can focus, but I can t! Damm Devrant!5
It's past midnight here and I'm studying for my first Calc 1 proctored test (derivative rules). I'm taking the class online and this is the 2nd test overall. The test is in 8 hours...2
I start my summer class tomorrow; Applied Probability and Statistics. I took a look inside the textbook for the class, and now I want to kill myself. Oh well, at least it's not Calculus 2.5
Is anyone else interested in the Characteristica Universali. It's very fascinating and not enough people know about how it can be applied to non neural network artificial intelligence.
Opened up my old notes. I wrote down something my linear programming and calculus lecturer said
"..we just calculate and calculate until we tire out.and hopefully we will get the solution." Yup.
Working on CS degree, just wondering...any tips for learning calculus outside the classroom? Because the classroom materials on calculus are lame ;)
