I was explaining git and Github to one of my friends during our boring maths class when he asked : "What is the difference between git and Github?". Just then another friend of mine sitting in front turns out and said : "It's like the difference between porn and Pornhub".

Umm wait what? Okay... 🙄😅

Must be my maths that is wrong...

For the maths-savy out there, this is a fine example of a 404 message. Awesome!

Never let anyone make you believe that just because you don't have a specific skill which is 'required' for your dream job/a job you really want, you won't be able to reach it.

I've heard countless times that I could never do anything with programming/linux (server) engineering because I'm freaking bad at maths. They always said it was a requirement to understand it in order to become good at those two things.

Except for a few simple tests with 'okay' marks, I never got a good grade for it and failed it entirely at every school.

Guess who's a programmer (free time) and a professional linuxer right now!

It just pisses me off when people tell someone that because they don't possess a skill, they won't be able to make it to what they would love to do.

When you have maths but your code is calling

When such people exist 🤷‍♂️ Wish I can undo what I saw 🙈 My day is already ruined 🤦‍♂️

Teaching maths to my niece and instead of 2+2=4, I wrote 2+2==4... someone needs break from coding 😂

My new sweatshirt. When maths loves LOTR

I suck at maths. Hard. But i can still write proper code. There, i said it.

I have never been fucked more in my life. A month ago I finished a 3 month internship for my last year of my education. And next to the internship I only have my thesis to defend and voila, I got my diploma! The internship itself went awesome, met some very interesting people, had a ton of fun working there and they were really happy about me.

But then it started, about 2 weeks after my internship started I got an email that my mentor (from school itself) had changed. It changed to a guy who's known for his insane way of teaching and being very unprofessional. Sometimes when I had a class on another level a bit further in the hall, we could hear him screaming while he was "teaching". He's really insane and should in no way be teaching to students. On top of that he has very little knowledge about CS, since he "teaches" maths.

So after I got the news I knew I was fucked. This guy is really hard to communicate with. And I'd never be able to have a decent, professional conversation with him.

So after I did everything I knew I was supposed to do, I tried to contact him on what else he'd need from me. His emails were crazy, unprofessional, and in no condition of being able to read and understand. So I started to get really annoyed but I didn't make this clear towards him. I even complained to another person of my school in a very polite way by saying that our communication wasn't going so well, I got no answer from that person and she even forwarded my complaint to him without asking for my permission and answering me.

So I kept doing what he kinda asked for, but had no idea if I was doing it wrong or right since I almost never got an answer from him, or the answer was not even an answer to my questions in the first place.

Today I had my presentation of the internship in front of him. It's the first time I see him since this school year. I give my presentation being quite happy of what I did at the company. When I was finished he starts bashing me into oblivion with ignorant questions, comments and very deconstructive negative feedback. Me not knowing what the fuck is happening and getting really angry inside standing there with nothing to say. I answered all of his questions as good as I could. But he was tearing me down so fucking hard. Because I only had half an hour I sticked with the most important stuff about my internship, didn't go to deep into all of it because he's not a fucking it'er anyway, and he asked for it specifically not to go deep into the project. But now he's saying I'm not giving enough information?! (He wanted to know what IDE I used?!?! What the fuck has that to do with anything)

So although I had a wonderful internship and I completed my project far better than the company had expected, my presentation went awful. I'm thinking that the guy was predetermined in failing me. How can I do a good job if he himself is not give a fuck about me. So now he's probably failing me for something he has no clue of what I did, and it's not even my fault.

I have no idea what I should be doing now. I start working in the second week of February but I probably won't get my bachelors degree until September now because of this fucker. I'm even thinking on taking legal actions. This guy just fucked my self confidence so hard. I'm fucking depressed right now

I JUST FINISHED MY FIRST NEURAL NETWORK!!!

But first of all, as I know you guys, it's spaghetti code and even I as a newb see places where I used too few-dimensional array or passed useless parameters or simply wrote too many redundant lines of code. I know it. I will make it MUCH better next time. Period.

But OMFG this made me scream from happiness today!! Just these few seemingly random numbers... I'm really done.. That's why I jumped into coding year or two ago..

And for some background, I didn't study any IT school, I'm just highschooler (general grammar school) who traded gaming for learning. Also my maths teacher teached NNs on university and is very keen to teach me, so that's that.

Now I wanna make the best out of it and I'm looking forward to write some well documented and flexible library, parallelized and everything (I'm gonna learn a lot in the process of doing this) better then FANN.

Maybe I'm gonna fail(99% probability but hey, I'm programmer beginner, I still think I can code everything I want). But if there is just one moment like when I saw this screen today, I'mma trade my life for it.

Sorry for taking your time guys, I was just genuinely stunned... A lot

Coolest thing i've built solo? I think it's my 3D snake multiplayer game.

It all started with a simple 2D snake game to teach programming basics at community college. Then i added a multiplayer mode based on a simple UDP implementation. Then i wondered how it would look ike in 3D and i had the idea to figure out how to implement a 3D engine by myself and i dove into the maths and wrote a simple 3D engine based on a windows forms picture box.
I showed the game to my colleagues and the loved it and we played it a lot.
So i added special mode boosters, and sound and map events and obervermode and observer polls.... you know it.

Here's a little collage of the journey...

Basically,
1+infinity = 1
But
infinity + 1 = NaN
My entire maths fundamental shuttered by the beautiful JS language....

They say, MATHS is a universal language,
They say, WAR is a universal language,
They say, LOVE is a universal language,
They say, SEX is a universal language,

I say C is the universal Language!!!

Anyone else who belongs to rest 14% ???

Those people who thinks they'll become a game developed coz they hates maths.

You know you're a programmer when you're doing math and you write == instead of = (Am I the only one who does this?)

Hmm...

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. Decide to learn optimisation algorithms
2. Realise that you have forgotten calculus
3. Decide to learn from the beginning

Stories of a lazy programmer...

What do you think about this news?

4 out of 3 people struggle with Maths.

I HAVE BEEN TRYING TO GET A MATHS PART OF MY RENDERER WORKING FOR TWO DAYS NOW AND IT HAS BEEN WORKING THE WHOLE TIME BUT I WAS USING THE WRONG VALUES TO TEST IT THIS ALWAYS HAPPENS TO ME I WANT TO DIE

1. Bullshit coding challenges that you wouldn't be any good at unless you were doing the same stuff like yesterday. For an entry level job.

2. Stupid tech leads, who can't see people smarter than them so they bring you down in an interview to feel better about themselves. They'll ask you stuff they know is outside of your scope. Mine often ends up being about networking.

3. Stupid HR questions, that basically ask you to ass-kiss the company.

4. When you're actually better than the interviewer at just about anything, including maths, so you have to tiptoe around their ego and not call them out on being slow.

5. When they don't even give you a chance. You enter the interview and by question 3 you know they're gonna reject you and you never had a chance to begin with, so internally you start screaming for the money you spent on the new coat to impress these fuckers.

6. Salary negotiation when you're broke and you'll work for anything that covers your bills and food, basically.

7. Explaining the gaps in resume or radical changes. Like why I was a barista for six months after six months of being out of work.

Quik maths

Some of these have been mentioned already but here they are, these things make me be a bit better at programming (at least I think so)

• sleep, I love sleep and I think a good night's sleep can do wonders

• music, music theory which is a language in itself and playing an instrument which teaches hand-eye-coordination and also creates patterns in your head, but certainly teaches us that you need to practice a lot to achieve your goals, that it's hard for beginners but gets a bit easier with time

• solving puzzles and riddles, I've been a huge fan of puzzles from an early age, it is something that teaches us solving problems and creating strategies

• other types of games that are helpful are games where you have to find things in a picture or in an environment, this has trained me a bit on finding nasty bugs in my code or at least syntax errors

• googling: sometimes you find out something that is not really related to your problem, but you remember it nevertheless and later on it can help you with something else

• maths, yes, you read correctly, I'm not a big fan of maths either, but what you learn in maths is that there are certain procedures you're often repeating and that you're always building on your knowledge and expanding it, sometimes solving mathematical problems is fun too ;)

• getting fresh air - self explanatory

• listening to other people's life stories, this helps me generally in life, to know that I'm not the only one struggling with something and so on

And I probably could go on with a lot more things, but I think that's enough for now

!rant

Anybody here heard of Project Euler? It's a series of maths/programming puzzles, and I think it's great fun trying to solve them. 😁

Preparing for maths exam be like.... 😑

I was asked to map a mathematical problem to an algorithm for first round of interview. I did it in 5 lines with O(n) and it worked. was told that was not the correct answer sent me an answer with O(n^2) and about 40 lines. in anger, I sent a five page mathematical proof along with analysis why mine was better. surprisingly, they took me in for second round. tanked it because I continually stuttered and froze. I was able to answer it once I got home. decided against sending it.

"I keep telling you, I'm not a pilot"
"and I keep telling you, you fly boys crack me up!"

I'm not a developer, but I'm doing some complex things and I need the benefit of computers to work things out, so I know enough programming to get me by. Recently one of the uppers decided that all the amateur spaghetti python programs I'd quickly slapped together should be developed into tools that the clients engineers can use!

"How long do you need!."
" I have no idea how to make something like that",
"but it's all just maths right! you can figure it out",
"probably, given long enough bu.. "
"okay get started and we'll check in in a couple of weeks" "hold o.." "I'll give your pride and joy to the graduate to fuck up while you're working on that" "wai.. " "anyway got take this call, good luck"
┗|｀O′|┛

So here I am.. I have no idea what I'm doing.

So since I have a working knowledge of python, fortran and VBA, someone suggested I learn nim, which was not what he sold it as. Then a software engineer that went to the same uni as me, suggested RUST! you can't mess up rust, and look at this I created (shows me a decent looking desktop application) "I'll help you out". But it wasn't really that easy.

Then I asked some questions... that was my first mistake, that's not acceptable until you know what you're doing apparently. Especially when the answers are in the docs you can't find in a topic you don't understand for a version you're not using solved with a tool you've never heard of for an operating system you forgot existed. Look at this moron asking a question.

Okay to be fair, I went through the rust docs and it was well written, and I do really like this language. But I do not have a degree in computer science, and so many docs for crates are just written with an expectation of a certain level of knowledge. As soon as there's a build error, it's at least 3 -4 days of me faffing about trying to decipher hieroglyphics.

..and the graduate is about to unwittingly commit manslaughter..

I'm sure whoever needs to fix this mess in the future will post a rant about this train wreck.

Spend 14 hours a week studying more with my free time.

Things to be studied:

-discrete math
-data structures
-algorithms
-coding challenges
-problem defining
-abstraction
-other relevant maths

Other things I want to improve:

-confidence at work
-reaching out to teams with questions
-social skills
-time management
-enjoying the little things
-patience
-consistency (with everything above)

Last big thing would be being more conscious with what type of data/platforms I am digesting everyday. Just like a good diet I want to get in the habit of consuming “good” useful content that’s thought provoking or knowable rather than fast food social media carbs

Wish everyone a productive New Year!

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."

🤦‍♂️🤦‍♂️🤦‍♂️

Tl;Dr - It started as an escape, carried on as fun, then as a way to be lazy, and finally as a way of life. Coding has defined and shaped my entire life from the age of nine.

When I was nine I was playing a game on my ZX spectrum and accidentally knocked the keyboard as I reached over to adjust my TV. Incredibly parts of it actually made a little sense to me and got my curiosity. I spent hours reading through that code, afraid to turn the Spectrum off in case I couldn't get back to it. Weeks later I got hold of a book of example code to copy out to do various things like making patterns on the screen. I was amazed by it. You told it what to do, and it did it! (don't you miss the days when coding worked like that?) I was bitten by the coding bug (excuse the pun) and I'd got it bad! I spent many late nights on that thing, escaping from a difficult home life. People (especially adults) were confusing, and in my experience unpredictable. When you did things wrong they shouted at you and threatened to take you away, or ignored you completely. Code never did that. If you did something wrong, it quietly let you know and often told you exactly what was wrong. It wasn't because of shifting expectations or a change of mood or anything like that. It was just clean logic, simple cause and effect.

I get my first computer a year later: an IBM XT that had been discarded by a company and was fitted with a key on the side to turn it on. With the impressive noise it made it really was like starting an engine. Whole most kids would have played with the games, I spent my time playing with batch scripts and writing very simple text adventures. And discovering what "format c:" does. With some abuse and threatened violence I managed to get windows running on it. Windows 2.1 I think it was.

At 12 I got a Gateway 75 running Windows 95. Over the next few years I do covered many amazing games: ROTT, Doom, Hexen, and so on. Aside from the games themselves, I was fascinated by the way computers could be linked together to play together (this was still early days for the Web and computers networked in a home was very unusual). I also got into making levels for Doom, Heretic, and years later Duke Nukem 3D (pretty sure it was heretic; all I remember is the nightmare of trying to write levels entirely by code!). I enjoyed re-scripting some of the weapons and monsters to behave differently. About this time I also got into HTML (I still call this coding, but not programming), C, and java. I had trouble with C as none of the examples and tutorial code seemed to run properly under a Windows environment. Similar for my very short stint with assembly. At some point I got a TI-83 programmable calculator and started rewriting my old batch script games on it, including one "Gangster Lord" game that had the same mechanics as a lot of the Facebook games that appeared later (do things, earn money, spend money to buy stuff to do more things). Worried about upcoming exams, I also made a number of maths helper apps, including a quadratic equation solver that gave the steps, and a fake calculator reset to smuggle them into my exams. When the day came I panicked and did a proper reset for fear of being caught.

At 18 I was convinced I was going to be a professional coder as I started a degree in Computer Science. Three months later I dropped out after a bunch of lectures teaching what input and output devices were and realising we were only going to be taught Java and no C++. I started a job on the call centre of a big company, but was frustrated with many of the boring and repetitive tasks we had to do. So I put my previous knowledge to use, and quickly learned VBA to automate tasks. It wasn't long before I ended up promoted to Business Analyst where I worked on a great team building small systems in Office, SAS, and a few other tools.

I decided to retrain in psychology, so left the job I was in and started another degree. During my work and placements my skills came in use a number of times to simplify and automate tasks. I finished my degree, then took a job as a teaching assistant while I worked out what I wanted to do next and how to pay for it. Three years later I've ended up IT technican at the school, responsible for the website, teaching a number of Computing lessons each week, and unofficial co-coordinator for Computing as a subject. I also run a team of ten year old Digital Leaders who I am training in online safety and as technical experts; I am hoping to inspire them to a future in coding. In September I'll be starting teacher training with a view to becoming a Computing specialist teacher. Oh, and I'm currently doing a course in Android Development in my free time.

And this all started with an accidental knock on the keyboard of a ZX Spectrum.

You know what really, really sucks about my school? Rant#00

I'm in my last year now and they removed one CS/IT lesson. Now I have two fucking 45min lessons (instead of three) of learning what I'm actually interested in.

Even worse: They don't provide and LK ("Leistungskurs" == advanced course) for CS/IT. Not like for Maths, English, German - okay but LATIN AND SPORT? Wtf
And this school calls themselves a MINT-school (Maths, IT, Natural Sciences, Technology).

EVEN WORSE: The 12th graders now don't even have a basic course CS/IT.

Fuck you school.

Jenkins doesn't care about maths

Wild calculus emerges

I was with the train in Vienna already when suddenly I received an email that the test can't be held today because of technical problems 🙄

Now we have it next week when I also have to study for a maths test, do statistics exercises and exercises for database systems
Fml

Gonna go to uni in a few months. So I applied to 2 companies for a side job. (10hrs/week - some kind of scholarship)

First interview:
Of all the applicants I seemed to be the only one with enough technical knowledge to be considered. :)
They rejected me still, because I don't have enough time to have a proper onboarding process. They offered that I could start off in the holidays in the second year of uni.

Second Interview:
Had a test with logic and a little bit of maths. Nearly completed that and then had a technical talk with their team lead. He said that I sound like I know my stuff. They are gonna contact me next week...

I think I aced the interviews, and being complimented on my knowledge feels validating.
Let's see where this is going...

Lol
Every time this pic makes me not to study "maths". 😂
So irrational:)

Interview nightmare

Happened with me☺☺

Ok friends let's try to compile Flownet2 with Torch. It's made by NVIDIA themselves so there won't be any problem at all with dependencies right?????? /s

Let's use Deep Learning AMI with a K80 on AWS, totally updated and ready to go super great always works with everything else.

> CUDA error
> CuDNN version mismatch
> CUDA versions overwrite
> Library paths not updated ever
> Torch 0.4.1 doesn't work so have to go back to Torch 0.4
> Flownet doesn't compile, get bunch of CUDA errors piece of shit code
> online forums have lots of questions and 0 answers
> Decide to skip straight to vid2vid
> More cuda errors
> Can't compile the fucking 2d kernel
> Through some act of God reinstalling cuda and CuDNN, manage to finally compile Flownet2
> Try running
> "Kernel image" error
> excusemewhatthefuck.jpg
> Try without a label map because fuck it the instructions and flags they gave are basically guaranteed not to work, it's fucking Nvidia amirite
> Enormous fucking CUDA error and Torch error, makes no sense, online no one agrees and 0 answers again
> Try again but this time on a clean machine
> Still no go
> Last resort, use the docker image they themselves provided of flownet
> Same fucking error
> While in the process of debugging, realize my training image set is also bound to have bad results because "directly concatenating" images together as they claim in the paper actually has horrible results, and the network doesn't accept 6 channel input no matter what, so the only way to get around this is to make 2 images (3 * 2 = 6 quick maths)
> Fix my training data, fuck Nvidia dude who gave me wrong info
> Try again
> Same fucking errors
> Doesn't give nay helpful information, just spits out a bunch of fucking memory addresses and long function names from the CUDA core
> Try reinstalling and then making a basic torch network, works perfectly fine
> FINALLY.png
> Setup vid2vid and flownet again
> SAME FUCKING ERROR

> Try to build the entire network in tensorflow
> CUDA error
> CuDNN version mismatch
> Doesn't work with TF
> HAVE TO FUCKING DOWNGEADE DRIVERS TOO
> TF doesn't support latest cuda because no one in the ML community can be bothered to support anything other than their own machine
> After setting up everything again, realize have no space left on 75gb machine
> Try torch again, hoping that the entire change will fix things

At this point I'll leave a space so you can try to guess what happened next before seeing the result.

Ready?

> SAME FUCKING ERROR

In conclusion, NVIDIA is a fucking piece of shit that can't make their own libraries compatible with themselves, and can't be fucked to write instructions that actually work.

If anyone has vid2vid working or has gotten around the kernel image error for AWS K80s please throw me a lifeline, in exchange you can have my soul or what little is left of it

Already wrote about wk92 but i have to add:

STOP MAKING ME ATTEND COURSES SO I AM EVEN ALLOWED TO TAKE EXAMS.

Like what the hell. You know when it comes to networking i'm doing okayish, coding straight A and then there is maths, let's not talk about it. BUT FFS I WAS NOT ALLOWED TO TAKE 2 OF MY CODING EXAMS THIS SEMESTER CUS I DIDN'T VISIT 2-3 EVENTS OF IT.

I am a coder. I aspire being a coder. I study software development. I just need to prove myself and some dudes can do it. Let me do my thing.
Btw, there weren't any mandatory events for maths. Of course. Why should there be. Yeah okay

Well, I just learned how much of a pain it is to learn the math for learning neural networks. I really should have paid more attention in high school.

I will learn, the hard way I guess...

Me: We have a bug, we are not sure what's really happening yet. We have to look into it.

Project manager: what's happening

Me: We dont know yet

Project manager: How much time will it take to fix it

Me: We dont kn... actually *quick maths* unknown multiplied by "I dont know" divided by logic and addition of past experience - how many times we cant put time on bugs multiplied by we have been here before subtracted by the sqaure root of can we have time to investigate first?

Me: ....mhh an hour or so (then I remember Harry Potter wasnt my classmate) oh actually 2 hrs (in my head, safer)

Bug takes 2 days to solve 🙃

Project manager: you said 2hrs

Me to myself: I said it's a bug. A damn bug.

Wk92 makes me realize why maths and coding are thaught together..

The time your prof last wrote a program was when computers were used for actual calculations only.😁

Javascript is better at maths than you

Lately ive noticed that 90% of rants is "heres this thing that would come up in the first 3 lines of any documentation but instead of that, im gonna rant about it"

The other 10% is meta rants like this and the last 5% is from people who are bad at maths.

Rooting your One Plus 5 will be an irrational decision.

Teaching my little sister Mathematics (Grade/Class 12. Not at all easy).

And I can really understand the textbook definitions in the chapters. Back then, I never understood a single line of it.

Am I a more sound mathematician now or reading poor documentations has improved my skill to read complex and minimal contents!

What? :D

What really helps me is knowing electronics, having a solid understanding of maths and experimenting around with computers and hardware in my spare time.

At some point you start to see programming as being more than just "kreating" (as Karlie Kloss would say) an "app".
I see programming as pushing your machine to go beyond its seemingly narrow boundaries.

Someone (QCat) on devRant offered me to be his contact, it ended up with him teaching me a HUGE lot of stuff, enabling me to now code an operating system alongside him (o and I learned maths, formalism, biology, chemistry, game dev, REAL C++, drawing [I still suck at all of them though] )

So yea, thats it from my side

I give math lessons to high school people in my "free" time. One of my guys needs to use calculator to compute sums with 0 and yet he wants to become a programmer 🤦🏻‍♂️🤦🏻‍♂️🤦🏻‍♂️

I've lost all fucking motivation to do anything at the moment.
Fuck not even gaming is much fun anymore.
Also amazing that I have so little time on Mondays that I can't even eat properly.
Literally living on caffeine, a spoonful of, like, porridge and water on Mondays.

And of course the nice bistro is closed on Mondays.
Then there is that motherfucker of person at school that just randomly starts sharing weird ass details with you and promptly started to break out in tears when she failed maths today.

Like fucking hell, then for some reason the same person fucks up everything in her volleyball group by literally doing nothing and complains when she gets hit by a fucking volleyball, like, she doesn't even attempt to dodge it catch it.

So much for that fuckery.

Then there's these little brats that just completely play asshole and are being jackasses to everyone including upperclassmen and teachers.
Grab em by the throat and fucking put them in a toilet.
Literally the reason why our school is generally known as the 'Drecksloch', literally dirt hole.

The fucking volume is driving me batshit insane in school to the point where I just start yelling at people.
Fucking kids, it literally doesn't cost you shit to just shut the fuck up.

Okay, vent over.
Sorry for that.

When you find out you passed the exam in which you guessed half of the answers ! 🎆🎉🎊
The algorithms of my brain seem to work well 🤣
This is now my second best module and I didn't study a lot hahaha

I feel like I've ranted this before. many times. but here we go again because Australia.

why do people think you can just ban math? like really?! that's what crypto laws do. they require companies to use shitty math. and what prevents me from using the good math? nothing! oh I mean... I won't use it? scouts honor.

you can't ban math.
literally billions of internet users don't fall in your jurisdiction.
no single jurisdiction can cover more than a subset of the internet.
I will use whatever maths I damn well please.
fuck off. please stop making us less safe.

I taught an intro to programming class today, brought back memories of highschool...

I remember when I started my first IT class in grade 10, it was a 50/50 split between IT theory amd programming. Choices were java or delphi...I made the uninformed choice to do java (thank goodness) and really enjoyed it. For some reason the logic and OOP concepts really made sense to me and i was well ahead of the class. I was always top 5 for maths/physics/chem and english literature but never enjoyed them for a second. On the other hand programming was something i could do for hours and still enjoy. In my final year we had to do a project, most of my class was still struggling with very simple for loops and jframes. The projects were terrible drag and drop NetBeans UIs that would convert meters to feet.

I remember being upset with the quality and ended up writing an entire client/server chat system with file sharing, voice notes, voice streaming, server admin controls, usernames and passwords (plaintext sql of course 😂), admins/mods/guests etc...

Got 100% and a personal recognition from the headmaster...found out yesterday the staff at the college have actually been using it since the time I left.

I don't know why i typed this whole story, something about teaching the kids where i was myself made me feel warm and fuzzy inside

Big maths test today.

Wish me luck!

We should start with demystifying tech...
For most people, modern phones, tablets and pcs are magical rectangles...
The law of Clarke says, that every sufficiently advanced technology is indistinguishable from magic.
And we have to tackle that.
In geography, we should talk about gps and glosnas
In English or foreign language lessons, we should speak about translator bots and language patters/abstractions
In physics, we have to understand the measurement devices
In politics, we have to speak about licenses of use, we have to speak about netneutrality as a political concept, we have to speak about snowden, shadow brokers, the vault, all the laws some shady imperial beauroticians pipe into our life.
Trojans used by the government and so on...
In cs concepts of operating systems, abstractions and networking should be taught, instead of using excel.
That could be done in math...
Well... No one should have to work with excel.
In maths they could use Wolfram alpha, rlang and gnupolt for example

Is this a bad way to traverse corners of a cube?
The objective is obvious from the context and I assume that programmers know how binary works.

Why do theoretical computer science and maths lectures mostly start at 8 am. I am a nocturnal creature to me is like having to wake up at 3 am for others. There are other kinds of people that like to get up early so here is a suggestion: Why don't we agree that all lectures start at 11:00 earliest? It is a good time in the day for a lot of people and I would have the time to inject myself with some Mate tea.

// First rant
currentUser.Post(new Rant("

Quick question here, not a rant (sorry).
I heard that you need a lot of math knowledge to become a developer. Is this really true? I don't see where the math comes into play while programming (especially complex stuff). I've been studying C# for quite some time (few years) and I consider myself fairly good at it.

Never came across the need to use !basic mathematics in my projects.
I know that to study computer science at an university requires a certain result in maths, but is that all you need math for? Getting into uni?

Could somebody explain this for me? I'd really appreciate it.", "maths,university"));

Why was the math book sad? Because it had too many problems.

Software engineers: "Maths is hard and scary!"

Also software engineers: "I've learnt to write a balanced binary search tree in c++ as interview prep!"

Mathematicians: "Have you guys heard of an AVL tree?"

It was not until 20 that I had access to regular computing. In school I had to take up Finance as my Maths was weak. I couldn't take Sciences including computers and how could I , my childhood wasn't as fortunate as my peers.

When I entered college I got my brothers old gaming pc as we had a couple of work laptops at home. I was always the inquisitive one. I got interested in web development just because of curiosity while I was on my first job and I hated it. I used to write article and freelanced and ran a website for friends where I learned a lot by trial and error. I single handedly learned mySQL, PHP and basic web development.

The main job was a core night from 11pm -8 am . Drained me and my social life drowned. I lost my brother in an accident. Silver Lining: I quit my job.

I understood I was interested in computers like nothing else. I single handedly learned a programming language. After leaving the job I took up classes to learn from root level in a structured manner: Web design and Development.

Now though I am jobless and I am searching for my second job it is for something I love. :)

So I'm not sure I understand this question fully, if it is meant only through code, than I guess none or those people I got to know while I was doing my algorithms and data structures project last semester where we were helping each other with our code
If it's meant generally through code related activities then I gained lots of friends in uni in classes and here on devRant of course and actually yesterday I got to talk unexpectedly about coding and programming languages on an event with a guy who actually studied financial maths in Vienna but now works as a tester and works with databases, that was nice

I'm hal laughting, half facepaling.

Use multiple servers they said
It's gonna balance automaticlly your load they said.

Well, they didn';t accoubnt for a MEGA badly writen API whic can block a whole server for a minute.

Or, but it's not the end !!!

So you see ? 1 at 100%, 1 at 0% ? Quick maths : Average 50%.

Autoscaling kicks in at average 40% for 2 minutes.

So it kicks in... Created a 3d server... Which is still booting !!

And some trafic redirected there.

Sooo. Users on a 100% server : Bad bad bad for them
Users on 0% server : No problems
users on a new 3d server : Wait 15 seconds, then it's like 0%.

Fun fun fun. At least I know now which fucking API does that.

Know i understand why my friends that are in to code does have better points at maths then me

Honestly? I was always good at maths and creativity. And so, programming was natural to me. I was always good at it with minimum effort. ¯\_(ツ)_/¯

... Algorithms were a whole other story tho. I'm still not confident 'bout any algos I program from scratch. But hey, if it works, it works. (that became my motto about algos, kinda)

Forgot one thing tho: looking at relevant code to whatever I'm doing, be it in a tutorial or stackoverflow. I don't need the text or tutorial or explanation, I need to see code examples.

# school suck
! coding

hello, hope im not bothering anyone with my adolescent problems, but im really angry towards school.

first of all,
the subjects get thaught much too slow.
like dafuq, why does our maths teacher need 6h to teach us what square roots are? Why does our history teacher need 10h to teach us about one single revolution???

and worst of all: why is everything accompagnied by long, repetitive, homework?

Also, why do they think that im bad just because i dont have the best grades??? im a GOOD average, without learning a TAD!!!

also, here i am, needing to learn maths for some it project.
when i ask any teacher, he doesnt explain it to me but says "you will learn that in class xy"

ok, then i guess i can teach it myself.
but when i take books into school to read em (remember, i already know the subjects), the teachers always take em from me.

also, im not allowed to talk to anyone. not even when idle.

so currently, i am trying not to get angry from this, tomorrow school starts again. after this year legally, i would be allowed to drop out.

could you please tell me what you would do? should i drop out? change school? change class? im open to reolly anything that possibly could help (my parents arent)

I'm doing a school project with one of my friends right now (little game in c++). He doesn't know c++ so I'm teaching him a little since he mainly does some mathematical functions and stuff (he's really good at maths). I told him "if you break anything I'm going to kill you" and he knows that I can be an asshole but he doesn't know about git and stuff. So I decided to play a little joke.

I put one single line into the code during he was on the toilet:
while ( new long long );

And I've been watching his reaction for about 1h now. I can see the sweat in his face but he's too shy to tell me its not working anymore😂😂 he's been trying to fix it but didn't find out yet. Let's look how far it will go

Would you guys consider Maths a programming language?

Understand low-level stuff better.
Be better at maths.
Stop procrastinating.

Windows' integrated calculator is so shitty I have to use JavaScript via DevTools to make proper maths

Wtf

Error: ID 2 is out of range (0..64)

How???

Did maths change while I was asleep?

Do I need an update?

None, actually.

Tho I should thank Mr. S, calculus teacher in my last year of highschool, and most of my physics teachers, and that one lady in first year of highschool teaching maths. I think those were way more important in teaching me logic than the folks who pretended to teach me stuff later in uni.

Oh, and that dude, Sir O.D., who was my professor of embedded microcontrollers in uni. Didn't teach me much programming, rather taught a memorable lesson on VHDL and how hardware really works.

Am currently at a jamboree where one kid said he was really good at maths. Then another younger kid asked him what 12 + 12. The first kid then said 24 to which the second kid laughed and said "twelvetwelve". Then the small kid promptly ran away yelling "catch me catch me".

They really do say the darnest things, but concatenation was unexpected :v

In a lecture and all the guy is doing is reading out of a book that was handed out at the start of term.

The saying those who can no do teach and those who can not teach teach maths comes to mind.

What am I paying for...

It’s been so long since I posted but this time it’s juicy again.

I got a coworker, no prio experience but already a year and few months into the job. He’s bad.
Magnitudes of bad!

We’re trying to teach him but to no avail. Everything about him sucks, major ballsack to be exact.

His attitude is to avoid every task, finishes nothing and then starts something new.

„Did you do X like we told you to?“
„No I started on Y, because I thought it [looks better, seems more interesting, thought that X is useless…]“

When you ask him much is done he is always „almost“ finished and needs your help on the „last 5-10%“. Yeah fuck that!

But that guy has a talent, his talent is to always give you technically correct answers which actually are complete bullshit.

„What are you doing at your job?“
„Staring at a screen and typing things.“ dude what?

That guy used the excuse „I can’t do maths“ on everything.

For an exam he had to calculate how long it would take to reach a certain amount if you would get some interest in that every year.
He asked the teacher for the formula. During the exam! And when the teacher didn’t want to give it to him he wrote plainly „can’t do maths“ on the paper and left

His code is of a quality as if he would write his first line in a week and then has the audacity to blame me and the colleagues for not explaining it right.

Ok you might think now we’re teaching him bad, or are too impatient. But honestly if you have to explain how to do a for loop for over about 15 months and get that attitude I think you get the right to be angry. I don’t mind explaining on how things work, even for the hundredth time, but then don’t tell me you understood, go behind my back, complain at a colleague how bad I explained, get explained by him and then do it again until you whored yourself through the whole staff!

It’s like he got the mind swiper from Men in black at home. Every day he hits the reset button.

He had a week of just changing indentation on a html file. Why? Because he wanted to find his style.

Yeah his style

if(a==b){
console.log(a);
}
else {
console.log(b)
}

And to produce code like that it takes him atleast 4 hours of trial and error.

And at the same time he goes arround and boasts what a super good programmer he his and that he can do some project work for them.
How we found out? Because he started working in those projects during work time at the office and asked us how to do things.
And he does so like a complete bastard!
Broken sql query? “No that query is perfect as it is, it’s supposed to show no results! But, just in theory, if I wanted to show some results, what would I need to change?”

I’m so mad about it and pissed on a personal level because he goes around blames everyone and the world for his short comings

OBVIOUSLY maths, physics, chemistry, Litterature, rethorics, sociology AND OF COURSE, playing chess

It’s the second maths pre-final exam today. Next after that - the finals.

I feel more ready than usual, I practiced more than I usually do before this test.

Wish me luck!

Impostor Syndrome...

I dropped out of university because of Maths (I'm not really that bad at maths, but that thematic wasn't really mine... But whatever) and obviously had no job nor any graduation (except my school thingy) and wasn't able to study something computer science related, because that's how it goes in Germany... (If you can't pass a certain subject, you will get blocked for the studies that involve that subject for 2 years or sth... Because I failed in Maths meant that I'm fucked)

So I started an apprenticeship to atleast do something and get that degree.

In my new company I really felt (and sometime feel it nowadays) like I'm the fifth wheel on the car and don't really achieve anything (but i really do).

That really fuckin sucks and hinders the fun that I could have in my job :/

Testers in my team have been told like 1000 times to follow the style guides that we all follow. That's not that big a deal. The big deal is that they were put on this project without having any mathematics background when the project is all about geometric stuff. So after me as a developer having to put so many hours to explain to them why the tests are not covering the requirements or why the tests are red because they are initializing the data completely wrong, I ask them pretty please to do the checks for the coding style and I have already been 4 hours reviewing code because not only I have to go through the maths and really obscure testing code to ensure that the tests are correct, but every line I have to write at least 4 or 5 style corrections. And some are not even about the code being clean, but about using wrong namespaces or not sticking to the internal data types. For fuck shake, this is embedded software and has to obey to certain security standards...

Lately I'm running into quite some negative atmosphere in meetings. Raise your hand if you think we all should improve our soft skills.

For example, we had a meeting with our client the other day. It was supposed to be only with the two most senior guys in the team and a couple of the less senior (just because one of us knows better the maths of it and the other one knows better about the limitations of the hardware), but in the end some other team members also joined.

In this meeting, we wanted to discuss an issue that had to be fixed. Quite a complex one. The main speaker from the clients, even though also technical, was having a hard time trying to explain properly to us what the issue was about. He was doing quite well, but it was complex enough. Well, one of the guys in my team kept interrupting him to ask very detailed questions (that would not help us understand it better, not until we got first the big picture). When I say "interrupting" I mean that the guy would half shout a question in the middle of a word from the client.

The client was patient and tried to answer, but our nice guy would keep answering back in a "gosh you really don't have a clue" tone.

We muted our microphone and one of the senior Devs asked the guy to please let them conduct the meeting, and that if he had such questions, he could mute the micro and ask them to us, so we knew we might have to ask about that.

Good. We unmute the microphone and 2 minutes after, our star guy goes in again and he even directs his question to someone else than who was talking (from the client).

Client gets pissed - I mean, I taught 12-16 year old teenagers for years and I don't think I would have hold it together for as long as the client did - and from then on all the meeting went in a really negative tone. Ending up with a call from the client to our senior guy to finish explaining in private the thing.

Well, our friend the interrupting guy not only got amazingly mad at the senior guy that (in private and constructively) gave him some advice on this kind of meetings. No, he also ended up spiraling into a close to insulting chain of emails towards the client -with his and our colleagues in copy- when he needed some specification.

Interrupting guy is 35yo and has been working with clients quite long. Our HR department still doesn't think we all should get communication workshops or something

Here's a task for the bored of you ;)

"Write a python script that prints out all numbers y from one to 10**30(including 10**30) that have two of these traits: [n**5=y, m**3=y, x**2=y] but not the other one; n and m are whole numbers."

Correct answer was about 103000
I can't seem to find the solution... Here's my (failed) try:

I once failed a subject during my masters (complex analytics and measure theory).
Next year I decided to give it everything I've got. I had grown to love it and could solve most problems they threw at me. Hand written an 80 pages long "book" distilled from all the notes, proofs and visualisations from all the lectures that year.

I only exerted this effort (even though I could've just "passed" this subject) because the lecturer was so damn enthusiastic about maths. Even though he wasn't a CS teacher this course was my best experience of a teacher at uni. He loved the beauty of the maths he was teaching and managed to make me love it too.

He was a maths geek and when I aced my final he told me he actually writes code too. He showed me some simulations he wrote while he worked on some theoretical nuclear physics stuff, because that's what he was into. Really cool guy. I wish more CS lecturers were as good teachers.

Got a pretty big maths test tomorrow morning. I’m actually a little scared because it’s a little too big for my liking, but I’ll have to manage.

Pissed off...😴

Medium-sized math test in 30 minutes.

Wish me luck!

(I am going to update, so stay tuned)

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.

Care to help me with some some-what basic math?

100 characters exist in the ASCII codec.

I'm trying to figure out the minimum amount of characters required to encode them. (= Turning each digit into a two digit char set that doesn't mach any other char set to enable me to do other things with them. i.e: A = dE)

It would simply be: x^2, where x is the number of minimum characters required.. But I don't know how to interact that with 100 to find x.

u is the coordinate of the point u in the u referential. PLEASE THERE ARE 26 LETTER. How about you use differen letter for different thing fuckin idiot

THIS IS FUCKING RIDICULOUS

Hello there devranters, long time no see
I have a question for all the computer scientists and students out there. Do you have book recommendations especially for the maths part? I'm in the process of buying some books, they're very expensive but if I'm going to buy they might as well be useful books.

Year 7 maths in 1984 - the teacher had a computer and showed us some BASIC commands to do mathematics.

I was spellbound. That year my father also bought a Commodore 64 for the family and I gravitated towards it. I typed program listings out of magazines and learnt programming almost by osmosis.

Today I spent an hour teaching a QA guy some GCSE level maths to be able to test my code

I got into programming because I couldn't solve a maths problem I'd been set, so my dad found an emulator for an old language he used to use a bit and managed to brute force it.

From there I went and learnt my first programming language, an unconventional choice of BBC basic 😛

One day I had a thought. (Dangerous, I know.) What if I could build a machine that took me up into the air and decoupled my inertia from the rotation of the Earth. So I would cease to move in sync with the Earth's rotation. Then I thought this could be a way to travel around the Earth. I wanted to know how long it would take to go around the Earth. So I got the circumference of the Earth and divided it by the surface speed of the Earth. I was really excited at this point.

40075 km ÷ 1670 km/hr = 23.997 hours

Oh ... yeah ... 24 hours. I guess the math checks out.

And this is why we need dev ducks.

The guy who leads the Objective Programming classes/labs told us that we have to make a game or an app to pass this semester.

I was so hyped, I've instantly started reading up on creating a 2D engine in C++ (which I don't like as much as C# but that was his conditions).

..as soon as I've created base for the engine, he said that the first version has to be console based.. so I'm like - okay, how do I show my 2D _graphical_ engine in a console?
So I came up with showing basic vector maths like movement towards a bearing angle and whatnot.

..now I've been pointed out that we are supposed to make a documentation, except it's supposed to contain info on ALL libraries and ALL classes our project will have.. which is insane, how can one predict what he'll need to accomplish the task? You can only know the half of the things you'll need, unless the project is way too simple.

I'm just plain annoyed, because this whole 'wow, I can showoff my mad skills' turned into 'wow, I have to do shit the tedious way and I'm already crying that I've picked a 2D engine and not a simpleton game like crosses and circles.

Oh my, never was i triggered more. Of course i can only speak for my experience. I study software development as focus.

First off, the starting languages and or concepts you learn.
Why the fuck do they start with java and don't even really explain how instances actually work? Of course they don't. Because it would be way too fucken much for a semester to go over garbage collection, Instanciation of stuff, allocation in such an advanced system, etc..
How about starting with something not 50% managed by a vm?
Good ol' C. And now don't tell me thats a rough start. We all know about these subjects or exams where it's all about sorting people out. Who will be able to manage a whole bunch of shit or who should consider something else.
Yo dawg sick idea: how about sorting it via the will to achieve the skill of coding?
Nah but we make the exams around coding (by the fucking way done on paper, what the hell) such a fucking breeze, asking you how to convert hex do dec.
Meanwhile maths will make you cut yourself in a dark corner, after you nearly shot yourself because of some lame-ass business-subject.

Epic comment:

1+2+3+4+....infinity = -1/12
SRC: Numberphile

Dear god, id like to file a bug report(see attached video)

Fuck!!!
I want to kill myself.
I just had the 2nd try for the math exam and I'll likely also not pass this time,
Means 1 try left and then i have to drop out of college.

I even did prepare way better this time than for the first try, and still the exam was so damn hard.

someone please motivate me to code again.

since one month i did nothing but digital art/youtube watching/maths/chatting but i did not code.
the main reason being that all my projects have bugs currently :/

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 BRAH

Maths...

I realized how much I suck at maths.
But seriously now, I started understanding the way things work, what makes them 'tick'.
It feels good to look at a random huge advert screen and immediately conjure up a pseudocode how I imagine the developers must have done it.

I freak out when I see cryptic maths notation.

My first software.. Okay. So first time I ever attempted was with my father, i was around 8 or so, i remember very little from it, but in nutshell, i somehow ended up at his job having day off school or something, no idea.

Apparently he was bored, so he decided yo show me... Basic. Yep, thats right. Frking basic. Anyway, he shown me some really basic stuff in basic, and pushed the envelope really hard, just trying to force into me more and more in these 8hrs. I started with filling screen with "o" characters. Most of times he was telling me what to write with elaborate explanation why. At the end of the day, we finished with simple maze game where player was "o" and maze walls was #. Without any goal, or anything.

Next day i was at point 0, understood nothing from it except how to handle keystrokes (and belive me, that for me was huge mindblow, and even bigger mindblow that it actually made prefect sense).

I dont remember much, but later i started with father-assisted c++ and some pascal. I immidietly loved c++ but dropped learning it for (NullPointer) reason.

Thats not really project imho, so now time for my actual first project.

It was about time when ARK survival evolved was a fresh thing, i was playing it a lot. Server admin became buddy. We all complained about max level cap, but to change it in config you needed to input whole new xp curve.

At that time i had great familiarity with google and computers, some thought i was some kind of PC god (seriously I heard someone saying so about me lol) just becouse I could ressurect most cases of broken windows. And I had next to zero programming expirience. It was about to change. I made first c++ actual program, that was making xp curve for you. It took me just bearly 2 days and was series of cin, cout, one file open, some maths in loop, and done. Maths was very bad. But i pushed it into steam forums, and one guy responded how.bad my math was, so we colabed on making 2 iteration. Took around week. Than half a year passed and we wanted go big. Go gui. I had no freaking idea how making gui looks like. Community liked my cli tool, we had quite a lot of downloads, why not go GUI. And thats when I discovered QT framework. And we had few features in mind... It took us half a year to make it. From 60 lines of code i jumped into 1k lines of code. We pushed it and immidietly started working on 4th version with much greater customizability etc.

Than i finished 18 and found a job. Job in php. I got it becouse I made this project.

Now project is abandon. This project also gave me a lesson that donations will not feed you.

Edit: and before you think about my father that he was nice person to show me code, trust me, i dont know bigger dick than him.

8 beds total, 5 bookings made, 5 still left...

I think I need to go back to class 1 and study matha again... This time, properly!

Packt.com (dev education books) is doing a survey of their readers. I don't fit into any of their boxes, closest one is data scientist.

I think I might really be a mathematician rather than a dev...

I hated maths at high-school.

I study both mathematics and computer science at Delft university. There's a difference between the approaches these two studies have.
Mathematics is usually about going to lectures, learning complicated stuff there and then using the obtained knowledge in a exam at the end of the course.
The CS courses are kore about engineering. They have practicals way more often than the math courses and the exams usually are of les importance.

It feels as if the "academic level" of the CS courses is lower. In math, we learn the real deep, abstract matter, while CS is more about "tinker up something nice in the practicals and you'll be fine."

I'm not sure if either approach is better, but I'm sure I like the maths version more. The CS approach is more HBO-like (HBO being the lower-level universities)
It is even that, generally speaking, the people who study maths seem more serious about studying than the cs people.
Not all of them, and no offense meant, just an observation.

Well, that was not really a rant. If you read up to here, I'm curious what you think about this.

Does anyone have recurring nightmare dreams about school?

I still get them even though it's > 10 years. Usually my dreams are about maths exams where I can read the question paper but can't make out the question.

Then other days I see myself walking up to class and I don't have my school bag with me.

Other times, I know my exams are gone bad and I barely wrote anything on the answer sheet and submitted it.

Other times, I see myself without pants in my classroom and everyone is pointing and laughing at me.

Ugh... maths.

Hi guys some advice would be appreciated.

I’m new here but have followed for a long time. I enjoy coding in my spare time, particularly web development but I am looking to make it my career.

Currently I work in mental health as a social worker, but ultimately the stress of the job and life in general has led to me being detained in a psychiatric hospital. So I’ve decided I need change.

I want to start a career I want to be in and that is as a developer. In terms of education, I started a degree in maths/cs a long time ago but stopped due to life events at the time. All the rest of my qualifications are around social work.

I’ve been doing my best to learn with Udemy and free code camp. Mainly looking at JavaScript. I also used to work in a charity where I did some (bad) php development and front end work.

Are there any self made developers out there who have any advice for me? I’m looking at doing a bootcamp but dunno if that will help at all.

Any help or advice would be really welcome. Cheers guys :)

Today was a rather funny day in school. School starts for me at 13:40 because our timetable planners are so qualified for this job.

First 2hrs: Physics, fine its good

Second 2hrs: Discrete Maths (however you want to call it)
Goal is to write a text (30 pages, 10, etc all those standard settings). Teacher prefers Latex over word, but we can do it in word if we want. We could choose a topic, I took primes because it looked the best. I decided to use latex because I'm a fetishist and it simply looks better in the end. A classmate was arguing with our teacher about ides: texmaker vs kile. And I'm like "I use vim". So my teacher is like kk

Later that class, when we actually started doing stuff I started the ssh session to my server because I don't know any good c++ compilers for win and I'm too lazy to get a portable version of cygwin (or whatever its called). So in my server I open vim and start coding my tool for Fermat Primes (Fermatsche Primzahlen, too lazy to actually translate). And this teacher seriously is the best teacher I ever met in my life. Usually teachers are like " dude r u hakin' the school server?" and I'm like bruh its just vim and I'm doing it this way because I cannot code on your PC coz I can't install a compiler. And this teacher is like "oh hey you actually use vi, all cool kids used it in 2000. I first though u were kidding and stuff..." And we continued talking about more of stuff like that and I have to say that this is the first teacher that actually understands me. Phew

Now I'm going to continue writing my 30 pages piece of trash latex doc and hope it'll end good

This is a real history..

So i went to my friend’s party.. and he invited this hot girl.. (u know the girl that would never talk to any programmer)..
so she started asking me about programming, maths, software...

and I was like wtf.. is this real? (because u guys know that this is impossible jaja)
Actually, we spent all night talking about it..

for some reason she started hanging out with me and my friend..

now we are dating.. kind of crazy uh?

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 now

Went to boarding school in England and our physics/maths teacher was a Cambridge graduate. Real bad sense of humor, probably took a bath once a month and wore the same suit all year. Skinny, glasses, clean shaven and ate Marmite and boiled eggs every day. Poster child for nerd world but boy did this guy help advance my math skills and love for physics.

Whenever I'm looking at automata, matrices, sets, anything confusing and maths based, I always remind myself how I used to be in awe of the year 6's (5th grades) getting to learn about negative numbers...

Negative number seem so much easier than sets and strings...

Tomorrow i have school starting.
Which inspires me to rant about how school fails. Ill omit the "arguments" - feel free to append arguments for my words in the comments. Lol

Dont get be wrong. I LOVE acquiring knowledge. And this is where my first point starts : PACE. My class is basically an assortiment of dumbfucks who dont understand anything without "learning by heart over the course of several weeks"

Ill give you a concrete example.
Our maths teacher wanted to make us think scientifically. So he invented a new type of numbers "root 6 numbers" that are formed like so:
a + b * sqrt(6)
Now he wants us to find out wether the sum of two root 6 numbers is also a root six number. this is all dandy, BUT CLASSMATES STILL DIDNT GET WHAT ROOT 6 NUMBERS ARE, EVEN AFTER SEVERAL EXPRANATIONS. Worse: they went to the main teacher to blacken the math teacher.
Another example would be the time our class needed to understand functions(x) : 4 weeks. Ik, as a programmer i have some ease, but four weeks is a bit too much.

Because of this slow pace, i am irreversibly bored of and in school.
And this leads to another problem: homework. Since i know most of the stuff (the few things i dont get at school, i research at home) the homework are useless to me and since the others dont get much, the homeworks are often more than abundant {in a negative way}.
So i dont do them - but that makes teachers disregard me. Which im sickened of.
Worse: often i dont get overly good grades (i honestly have no clue why. I know everything and go over most of the stuff with my menthor),which empowers teacher of the argument of "you are not good enuff, so you cant read in class".

It would be JUST FINE if the only problem were teachers - but my peers are horrible too.

I know our brains are growing, but thats no reason for being stupid.

I literally get told that i need to stop wearing shorts because they look horrible.

Yep. Also, most people think they are empowered of teaching me and talking about my defaillance - because they do their homework. Even though they know i know stuff better than them.

Now to one of the worst issues: a group work where we had to de a Radio report. The guy (the one who thinks he is intelligent BECAUSE he has good grades) invited himself and his gf to me, he wanted me to translate 22 pages from german to english (because he was too lazy to write in german), wanted me to do audiorecording, audioediting and writing of a report. When i left the group because i was called "weakest link" he spread the word that i he had done everythinh and that because i left his group had failed (noticed the flow in logic?)

NOW everybody thinks of me as stupid weirdo. And honestly - i think i will stop listening to them. Ive always hated people, i dont need a significant other.

Even though this will come with the secondary effect of me being gossiped at.

But honestly its fine.

You might have noticed my elojquent way of expressing myseld. I did that in order to show that i am, despite my grades, overly proficient in english

Ok. So now comes the conclusion. What should i do? Do you Think that i am like that because im pubescent myself? How can i stop having nightmares of every possible social situotion that could occur?
Does this have to do with me being a dev?

Well. ありがとう for reading.

My Windows 10 VM gloriously just shat itself so badly, it's now stuck in a BSOD bootloop (first time ever I managed to get a BSOD in a fucking virtual machine btw) and I need to reinstall it. So I need to download the newest Win10.iso.

But I'm also currently working on a university assignment that requires me to be connected to the university-network via a VPN that's slower than my 90s ADSL connection (~1Mbps) (see my previous rant). So to download the 4.7GB iso it'd take.... I'm bad at maths, so let's just say fucking AGES.

So I spin up another VM with a bridged network to download my Win10.iso with Gigabit speed to set up another VM.... wonders of modern technology

I think spotlight on iOS 13.x is a little tired.

"What is going on... this should work?!
Is my maths wrong?
My maths is wrong...
Oh no!
It's a model view projection matrix?!
I'm shit if I'm failing at this, it's 3D dev 101!
I got a first class degree... I don't deserve any of this or this job!!"

<2 seconds later>

uniforms.viewMatrix.set(camera.matrixWorldInverse.elements);
uniforms.viewMatrix.set(camera.projectionMatrix.elements);

"You set the same uniform twice you tool, due to copy and paste..."

Imposter syndrome in my early days put myself into a roller coaster of emotions. I always compared myself to others to the detriment of myself.
Thankfully overcame that working with some great guys.

But yeah, coding has impacted life for the best though. The challenge, creativity and constant learning is beautiful.

My maths book contains some nice stuff too not just good old boring stuff... But god damn killer bunnies too who will kill you with a right angled triangle.

I don't know if this can be classified as a legit "regret" or not, but anyway (hence no wk78 tag).

I've always chosen to focus more on the theory behind computers and computing rather than on practical dev skills. Not saying that the more theoretical things aren't fun - concepts from theoretical CS and maths still regularly blow my mind, as do the more "esoteric" languages like Haskell, Idris, and Coq. However, after seeing you fine folks here at dR talk about practical development, it feels like there's a whole world of stuff that I've missed about computers and programming, especially web programming. I think I'll tackle that next when I have some free time, maybe spend some time learning PHP to see what all the hate's about... (really though, it must do something right if it has such a huge userbase, plus, I think devRant uses it too...?)

Anyway, just wanted to say that you folks are really cool and an awesome source of inspiration. Best community ever.

You got it all wrong, it's being a dev that helped me a lot in a lot of domains: organization, logic, basic maths that I kept struggling with for years, and the love to learn new stuff everyday

Stuck in a stalemate maths eq, guess I'm bad at it
case 1:
971 - 291 = 680
680 - 15 = 665

case 2:
291-15 = 276
971 - 276 = 695

Why the fuck both eq different?

In high school I absolutely hated business and science subjects(phy, chem, bio) as well.
Not to forget fucking maths. Calculas and all that shit I never paid attention to.
I chose CS hoping it would rid me of maths.
Fell in love with programming the very first semester.
Now I'm in my last semester and a freelance Web Dev.

Vocabulary for the day.

Screed - An abusive rant is called a Screed.

Usage - I'mma screed the shit outta dem pathetic species of blood sucking parasites AKA dickhead project managers who do dem (developerEstimatedTime/2) quick maths.

Fuck you

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.

I'm intrigued, what are you all trying to learn in your spare time and how?

I'll go first, brushing up on maths by reading K A Stroud advanced engineering mathematics.

He's got an intro level book that's also very good.

Hi all devRanters (if that is a thing),

I'm currently in grade 10, and I'm looking forward to a career in computer programming. I find that sometimes Maths is very intimidating, as such, I want to ask all of the devs here: is Maths really that crucial to the job? Or is it merely a requirement to go to university and get a CS degree?

Thanks in advance!

2+9 = 29
4+0 = 40
then,
5+4= ?

A noob here, please don't judge too hard.
My major is maths and philosophy(mainly doing logic in philosophy), and even though we had python in maths, it's so basic I don't even think I can say I learnt anything (sololearn on my phone taught me more lol)
Does anyone have experience of transferring to IT after or during a maths degree? Not rly asking for advice, just want to hear life experiences and maybe learn something!

Let me start this off by stating I'm a Java dev, and a noob with C++.

Thought it'd be cool to learn some OpenCL, since I want to do some maths stuff and why not learn something new.

So I sat down, installed Nvidia proprietary drivers, broke my x-org server, purged, reinstalled, rebooted and after a while I got stuff sorted out.

Then on to my IDE. I use CLion and it uses Cmake. C++ noob knows shit about Cmake, so struggle for two hours trying to figure out wtf is going on with the OpenCL libs and why they're only partially detected. Fml.

Finally, everything is configured and I'm set. I start working on a Hello World program using OpenCL. Finish it in 20 mins, all good. No output. Do some googling, check my program a million times. Nothing wrong here. Check the kernel, everything as in the tutorial.

I start checking error codes after a while reported by OpenCL (which I had no clue was a thing) and I get some code saying the program was not created properly (to run the kernel). No fucking clue what's up with that. Google around, find another tutorial, rewrite my code in case I'm using outdated code or something. Nothing.

Fast forward an hour, I find out that OpenCL has logs! So I grab some code from the website I found it on, and voila, I finally get some info on what's going on.

Get a load of this bs.

In the kernel file, so that OpenCL knows that it's a function to run, you have to put __kernel. But in all the places I read, it said to put it as _kernel.

Add the underscore, compile, run and everything is perfect.

Then I tried just putting 'kernel'. Also compiles and runs fine.

Two hours hours and my program was fixed by adding an underscore. IF ONLY C++ GAVE AN INDICATION OF WHAT BLEW UP INSTEAD OF SITTING BACK AND BEING LIKE "oh wow man feels bad, work some magic and try again" THEN THIS WOULD NOT HAVE TAKEN SO LONG.

Then again, it was OpenCL that was being shitty with its styling enforcement or whatever the hell the underscore business is. But screw it. C++ eats shit too for this. Sure, maybe Java babies you by giving you the exact error and position that the error took place at. But at least that way you don't waste hours of your life chasing invisible bugs 😠😠

I'm going to eat some food... Too much energy was consumed fighting the system... Then I'll get back to OpenCL because 😇 but that doesn't make it less bs.

So after a couple years working at this company, the faculty I graduated from introduced a postgrad (masters) course in data science. I was always interested in the field, so I said fuck it and jumped the bandwagon...

I'm starting this week, I'm kinda worried my knowledge of maths and statistics got a bit rusty since graduation. Also most students there will be 4 years younger than me, and I'll keep doing my full-time job at the same time. But hey, at least I'll break the routine, and I can always quit my job if it turns out I can't do both, so whatever.

That's all folks!

Man i fucking love my current living situation. The people are so fucking nice here, my neighbours almost all go into the same school as me and are therefore technical versed/share the same interests. My School is super awesome due to some of the teachers, where you can learn so much. Really starting to have a passion fo programming although it takes up so much of my freetime, i nearly don't do anything else anymore but I want to learn as much as possible.

It's a super nice day even though I have to study maths all day but fuck it! That doesn't stress me!

And all it really boils down to is how you perceive problems and the like. Either you let it get to you or you don't. Now everyone have a nice day :)

1. Solving problems gives me orgasms
2. Code allows me to be extremely creative
3. I love logic (and maths too, but to a lesser degree)

Ok please guys I need a little help here.
So I'm in my second year of my Computer science course and all subjects except one went well.So I failed my first year maths module so I decided to redo it and study much harder.Low and behold I worked really hard towards passing the exam but it was still extremely difficult.So I haven't gotten my mark and all but if I do fail it again I will not be able to continue in this University.I do not have a plan B at all and I really don't know what to do.I live in South Africa(if that's relevant).So basically if I pass I'll continue with the course but the question is what do I do if I don't pass.should I start working or try another degree at another University which will be another 4 years.PS I'm heading for 20 years old in a few weeks time.I appreciate anyone who gives any feedback.

Started playing around with HTML and CSS when I was about 8. Tried JavaScript but it never stuck. Started to learn a bit of Python when I was about 13 and enjoyed it, but never applied it to anything other than some maths. Used some basic ActionScript in Flash animations. Wrote some simple VBA in Excel. Learnt Matlab during my Engineering degree. Now I use Mathematica for my PhD work, Python for fun and useful bits of software for myself, and the occasional bit of PHP and whatever else I need at the time to get something working.

I needed to rewrite pagination from:

A) 1 ... [3] 4 5 6 ... 13
B) 1 ... [4] 5 6 7 ... 13

To:

A) 1 2 [3] 4 5 ... 13
B) 1 ... 3 [4] 5 6 ... 13

And the maths got me a headache

I'm an apprentice software engineer, have been for about a year now. I feel so dumb all the time. Used to be I'd just teach myself at my own pace for about a year or two (which was slow, on and off because of life getting in the way). Now I'm surrounded by programmers with decades more experience than me and I can't help but feel inferior.
I want to get better faster but, I work full-time now so I don't know how to supplement my studying. I've been studying linear-algebra online because my maths is crap and I remember one of my colleagues mentioning that it would be useful. But now I'm not sure because apparently discrete mathematics is better.
I also need to keep up with Java since that's what I'm learning in university but, I'm mostly using React/Typescript in my current project. By the time I finish work I don't even want to look at a line code and I lack the self-discipline to force myself to study in the evening.
I need to pick a direction and stick with it but, it's seems to just be increasingly harder as I've gone on.

Finally finished an algo to check an image for grouping of pixels that will form a rectangular area. I got the grouping to work on one image, but found it was utterly failing on another. I went through every step of the algo and still could not find the solution. The 128x128 image was working, but the 128x16 image was not. I knew it had something to do with the dimensions. Started thinking it was overflowing a buffer somewhere. So I started putting asserts in the functions that abstracted the buffer access. None of the numbers exceeded the proper bounds. It was close to bedtime so I finally gave up. I was tired. Then I realized it wouldn't be until the next evening when I could look at this again. So I got up again and started looking at the code again. I had a loop to check the output of my algo that I did the memory access of the buffer. It too was not fully filling my temp image to show how the algo was working. WTF!

Then I finally realized the flaw:
buffer[x+y*height]

And my test loop to test the algo:
buffer[x+y*ymax]

I kept overlooking the error because I was sure it was right. Also my asserts for the functions to access the buffers? They only checked the inputs x and y. So it didn't help that the math was wrong for reading and writing the buffers. It also worked fine on 128x128 images because the width and height were the same.

It is funny that I struggled with this part. The algo was actually surprisingly easy to formulate. I just looked through every point and checked a buffer to see if that point was used. If not then I would attempt to grow in the x and y direction the shaped of that point based upon pixel color. This was saved in a structure while growing that point. Then when that rectangle could not be grown further the inner loop would continue checking used points again.

I still have work to do to use the data this algo produces. I need to now figure out how to parent the rectangular areas to each other. I will probably use my check buffer to keep track of these rects by an index. Then do adjacent checks to determine parenting. Eventually I will have to extend this algo to 3 dimensions, but that should not be difficult.

!rant thinking of learning machine learning. Have no much maths background. Where do I start?

Links, blog's, books, examples, tutorials, anything. Need help.

The c++ 'Eigen' library. It is by far the best library if you're in need of maths constructs, speed wise. And the only maths library that has an API that isn't a pain to use.

1 / 998001 = mind-blowing recursion

I just learned C and I have created some projects like Parking System and Library Management System. My problem is I don't know mathematics and I want to learn DataStructures & Algorithms and become pro in it. In the whole September I will still be focusing on C and create more projects. I have started learning Mathematics today from High School level to College level. I thik maths will take 1 year to complete. After September in the October I want to start learning C++ and finish C++ till the end of Dec 2019. I want to know that do I have to first finish my maths learning which will take 1 year then I should start learning Data Structures and Algorithms? As I said I want to become a professional in Algorithms. I think its not possible to learn DS&A yet I have to wait 1 year till I finish learning my Maths. I can't do more with C & C++ without knwoing DS&A? If I started learning DS&A with C++ in the future then I can't become good at algorithms? I want to do competitive programming and be at Top 1 of Hacker Rank and other sites like this.

Went on a Hackathon with two friends. They didn't do shit. This week, they told me that they only knew c#, so we should switch to that. (I use Linux so I shouldn't have accepted that) Just learned that they are going to a maths camp this week and the deadline is next Sunday. Dotnet core CANNOT PARSE FUCKING JSON. I'll rewrite it in node.js, and hope that I can type fast enough to finish in time. Fuck me, fuck my lazy friends and especially fuck Microsoft for saying that they support Linux while providing a dotnet for Linux published in 200-fucking-5

Not paying more attention in classes, that way i wouldn't have to be retaking maths :(

!Dev related
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
You leave.

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.

Lawyer maths is different to actual maths, and it's fucking confusing.

Fuck this. I need a data science job title.

We're implementing something based on a paper, as requested by our head of DS. The head of DS hasn't read the paper. I have. So has my team. We're discussing something, they don't understand how we should do something, I understand it coz I have a maths background but they want to ask head of DS to be sure. Who hasn't read the paper. I knew he hadn't read the paper because he came up with a stupid newfangled solution to a problem, when the paper already solves the problem, so his idea isn't needed but we implemented it as an optional feature to keep him happy anyway. So why the fuck are we asking him? He's not an idiot, but he does throw a lot of stuff at the wall hoping it'll stick. And he's not very methodical. And not reading the paper is unprofessional as fuck.

can somebody tell me why a string has (n*(n+1)/2) substrings?

I didn't clear my exam. Now it's my last chance have to pass at least in 4 subjects from 8 boring subjects otherwise I will be detained 😥 I hate fucking theory and fucking maths 😭

Can anyone suggest me a good tutorial about maths used for machine learning

A-level results lads out tomorrow, got an A, B, B & C in Geography, Maths, Chemistry and Physics, think it'll be good enough for a CS degree at Edinburgh or Queens?

When you exeed the assumed time in mpv while playing a stream. Double minus! (--) 😂

Really wish there was a site that contained a library of fundamentals of development processes like basic networking, specific game mechanics and the such.

I don't mean show code but explain some of the maths and algorithms that go into the programming itself.

If I had the time I'd build it...

I love doing maths and used to score well in 10th and then my worst decision of taking commerce rather than non-medical.

I scored really bad in 12th, where I met a girl but was too shy to talk. Ah!! Anyway she was the only reason I used to attend classes.

Then I tried for B.Com which I was least interested and maybe because of destiny I did not get admission in any college. :D

So ended up in BCA, whoa life changing moment that was only computers, code, technology and atlast found a girl.

Now building up my code with my future.

The whole world use greek letters in maths. Greeks just only use letters. It has to be horrible to always feel like in a maths class.

I have working for software engineering for the past 8 years without any degree at all. However, in my latest job interviews one of the things I mainly lacked was understanding and applying the algorithmic concepts. As I hadn't maths since I left college, what would you recommend me?

I was looking for some kind of a course (it is always better when you have someone with whom you can discuss with), but such a specific one doesn't seem to exist in Portugal, and taking an entire degree because of algorithms is not an option to me.

Ideas?

PS: I am currently working, however I do understand that a new algorithmic thinking would help me in my daily job.

When I was about 10 years old, my maths teacher at school brought his Sinclair ZX80 into the classroom at the end of the Summer term to show his pupils. He'd written a couple of Math quiz programs that he showed us, and for 99% of the students that was enough - it was nice curiosity and diversion and the end of the school year. I however was fascinated by this little white lump of plastic.

When I came back to school after the summer holiday, everything had changed in that classroom.

Around the edge of room were about eight brand spanking new ZX81s with 16k RAM packs. They were all connected to a single tape deck in the corner of the room, into which our teacher could insert a cassette with the latest Maths program he'd written. All the pupils would be instructed to type LOAD "" and he'd press play on the tape deck - early networking!

From there I got my own first machine (a 16k ZX Spectrum) but I've never forgotten that initial contact.

Sometimes wondered how the avalanche effect works on hashing a message,tried making mine but was shit, I guess I need a PhD in maths lol

Me: can you go and stand over there please.
Lawyers:

Okay. Four work days remaining this week, but still six days worth of work. My project manager sucks at maths.

I was thinking to read some books on algorithm and mathematics required in programming, especially for CP. After some searching I got across some books that are considered great in the field. Among the books, 'Introduction to Programming by CLRS', 'Algorithms Design Manual by Steven Skiena', 'Concrete Mathematics by Donald E. Knuth' and 'The Art of Programming by Donald E. Knuth', in which order should I read them? I've already started reading CLRS as it would be required in my college course too.
