Started being a Teaching Assistant for Intro to Programming at the uni I study at a while ago and, although it's not entirely my piece of cake, here are some "highlights":
* students were asked to use functions, so someone was ingenious (laughed my ass off for this one):
def all_lines(input):
all_lines =input
return all_lines
* "you need to use functions" part 2
*moves the whole code from main to a function*
* for Math-related coding assignments, someone was always reading the input as a string and parsing it, instead of reading it as numbers, and was incredibly surprised that he can do the latter "I always thought you can't read numbers! Technology has gone so far!"
* for an assignment requiring a class with 3 private variables, someone actually declared each variable needed as a vector and was handling all these 3 vectors as 3D matrices
* because the lecturer specified that the length of the program does not matter, as long as it does its job and is well-written, someone wrote a 100-lines program on one single line
* someone was spamming me with emails to tell me that the grade I gave them was unfair (on the reason that it was directly crashing when run), because it was running on their machine (they included pictures), but was not running on mine, because "my Python version was expired". They sent at least 20 emails in less than 2h
* "But if it works, why do I still have to make it look better and more understandable?"
* "can't we assume the input is always going to be correct? Who'd want to type in garbage?"
* *writes 10 if-statements that could be basically replaced by one for-loop*
"okay, here, you can use a for-loop"
*writes the for loop, includes all the if-statements from before, one for each of the 10 values the for-loop variable gets*
* this picture
N.B.: depending on how many others I remember, I may include them in the comments afterwards19 -
Why am I such an average ?
It's just a sad realisation. Nobody cares but I wanna send this out there, just to write thoughts.. I am 18 in 3rd year of high school (grammar school so nothing IT related, basically waste of time) and in IT I'm all self taught but I feel like I could be better if I just didn't [something]..
I feel like I wanna learn so many things but when I look at you, it seems like a common problem in the IT sphere so hey, average guy joining the club.
I also feel dumb when programming. I didn't manage to learn C++ in it's entirety because to really accomplish something, you've got so many ways to do it and finding the best one requires deep understanding of the tools you've got at your disposal with the language and I feel like I'm not capable of this(self learn, in school/Uni that's different story).. But many (most) of you are. I've tried many coding challenges and when I got it working, I just saw how someone did it in one line just by layering functions that I've never heard of..
Also, we've got kinda specific national competition here in many fields including IT for high schools.. And the winners always do sometimes like "AI driven Life simulation" or "Self flying drone made from ATMega from scratch with 3D simulation in C# to it" or "Game engine" or whatever shit and it's always from grammar schools and never IT related schools.. They are like me. Maybe someone helped them, I don't know, but they are just so far away from me while I'm here struggling to get the basic level of math for any kind of machine learning..
Yeah I've written Neural Network from scratch in C but meh, honestly it's pretty basic stuff .. I'd rather understand derivatives which we're going to learn next year and I'm too lazy to learn it from khan academy because I always learn something else.. Like processing (actually codetrain started teaching tensorflow so that might be the light for me...) Or VHDL (guys you can create your own chip / CPU from scratch and it's not even hard and OMFG it's so fucking cool , full adder done yay) or RPi or commodore 64 assembly or game development with Godot and just meh..
I mean, this sounds exactly like not knowing what to do and doing nothing in the end. That was me like 6-12 months ago. Now I'm managing to pick 2-3 things and focus them and actually feel the progress.
But I lost track of the original point.. I didn't do anything special, every time I'm programming something, everyone does it better and I feel dumb. I will probably never do anything special, everyone around says "He's still learning he's genius" but they have no idea.
I mean, have you seen one of the newest videos on Google's YouTube channel (I openly hate them, but I will keep that away for now), something like "Sarah story" ? It's about girl that apparently didn't care about IT but self learned tensorflow on high school. I think it may be bullshit (like ALL of their videos ) but it's probably just fancied, not complete lie.
And again, here I am. I now C but I'm incapable of learning to program good which most of you did and are now doing for living. I'm incapable to do anything cool, just understanding what everybody else did and replicating it. I'm incapable of being clever.
Sorry, just misusing devrant to vent a bit17 -
I used to think I was so clever by viewing the source code of websites, and would just scroll through it for fun, but what really got me started in programming was the TI-83 calculator I got in grade 10.
You couldn't view the code of most programs on that calc without a computer connection, but I managed to get my hands on the source code of something simple and learned how to prompt for values and calculate things with them. Before I knew it, I was making little programs in BASIC that did formulas for me (Area/circumference of a circle, etc.). One of my professors caught me showing my calculator to another student in class, and assumed I was being a bad student. When I said I made a program as a shortcut for one of the formulas we were learning, she tried to call my bluff and said to write the whole program on the whiteboard for the class to see. 10 minutes of writing and more than one blank stare from my classmates later, the teacher just waved me off and continued the lesson. I was chuffed :-). I made these simple programs for all my math classes throughout high school.
Unfortunately, my first year of university I took a CS course, and my teacher was probably the worst I've ever had in my life. I decided it wasn't for me, and though I did maintain my general aptitude for tech (and was still the person who fixed everyone's printers and viruses), I took a different path, eventually getting an Arts degree in Anthropology.
Where I live, the market for this is more than stale. In fact, it's completely flat, so I thought I would take a course about programming with Arduinos for fun and see if I should return to school for a different certification. It was AWESOME! I made a wireless weather station with Xbees and sensors and built my own anemometer.
I got a job at a manufacturing company, and had the fortune to build a robot which eventually made it's way to the second season of Battlebots. The level of intelligence and enthusiasm I encountered really inspired me, and now here I am at 31, halfway through a BSc in Computer Science and working for a company that makes 3D printers.
It's been a long journey, but the adventure always starts anew tomorrow.5 -
"Make a 3D cube using the skew and size functions in Microsoft Paint on Microsoft Windows 7"
I shit you not, this is a genuine task you can allot in the school-leaving exams(maturita) at my school.
A 3D FUCKING CUBE! IN MOTHERFUCKING MS PAINT!
I mean it would be a kind of an easy task if MS Paint did the math correctly but for some fucking reason when you skew something in MS Paint it also magically shrinks! It is not MS Paint, it's M$ Pain.11 -
My first dev project was making a small 3D engine in GameMaker 7 when I was 14. I had been using gamemaker for two years then but I never got past the "platformer movement and collisions" and "top down movement and collisions"
It was the first thing I made myself without following a tutorial and spend quite a few afternoons at school to ask my Math teacher to explain things like sin cos and tan. Words I saw on the internet but did not understand.1 -
QA personal voice assistant that runs locally without cloud, it’s like never ending project. I look at it from time to time and time pass by. Chat bots arrived, some decent voice algorithms appeared. There is less and less stuff to code since people progress in that area a lot.
I want to save notes using voice, search trough them, hear them, find some stuff in public data sources like wikipedia and also hear that stuff without using hands, read news articles and stuff like that.
I want to spend, more time for math and core algorithms related to machine learning and deep learning.
Problem is once I remember how basic network layers, error correction algorithms work or how particular deep learning algorithm is constructed and why is that, it’s already a week passed and I don’t remember where I started.
I did it couple of times already and every time I remember more then before but understanding core requires me sitting down with pen and paper and math problems and I don’t have time for that.
Now when I’m thinking about it - maybe I should write it somewhere in organized way. Get back to blogging and write articles about what I learned. This would require two times the time but maybe it would help to not forget.
I’m mostly interested in nlp, tts, stt. Wavenet, tacotron, bert, roberta, sentiment analysis, graphs and qa stuff. And now crystallography cause crystals are just organized graphs in 3d.
Well maybe if I’m lucky I retire in the next decade or at least take a year or two years off to have plenty of time to finish this project. -
I'm really not sure. When I was 7-8 years old, I liked to view source in IE, then I somehow managed to use Javascript in the browser. First only some dumb opening of windows. And I liked Batch, so I made some files for copying, backup and stuff.
Then I got to PHP during the years from some online tutorial about making dynamic websites. My website was more static than stone, but yeah, I did page loading with PHP! Awful experience anyway, because I had to install Xampp, get it work and other stuff. 11 years old or so. (and I used Xampp only as a fileserver between laptop and desktop later, because.. PHP4... just no.)
As 12 years old or so I experienced my first World of Warcraft (vanilla) on a custom server in an internet cafe and I thought it's a singleplayer game. When I found out that no, I googled how to make my own server (hated multiplayer back then and loved good games with huge storylines). Failed miserably with ManGOS, got something to work with ArcEMU. There I learned some C++ basic stuff, which I hoped would helped me to fix some bugs. When I opened the code I was like: "Suuure." and left it like that. I learned what a MySQL database is, broke it like four times when I forgot WHERE and still rather played with websites i.e. html, css, js and optionally php when I wanted to repair a webpage for the server. With a friend we managed to get the server work via Hamachi, was fun, the server died too soon. Then I got ManGOS to work, but there wasn't really any interest to make a server anymore, just singleplayer for the lore. (big warcraft fan, don't kick me :D )
I think it was when I was 13y.o. I went to Delphi/Pascal course, which I liked a lot from the beginning, even managed to use my code on old Knoppix via Lazarus(Pascal). At this age I really liked thoae Flash games which were still common to see everywhere. So I downloaded .swfs, opened and tried to understand it. Managed to pull some stuff from it and rewrite in Pascal. Nope, never again that crap.
About the same time I got to Flash files I discovered Java. It was kind of popular back then, so I thought let's give it a try. I liked Flash more. Seriously. I've never seen so much repetitiveness and stupid styling of a code. I had either IDE for compiling C++ or Pascal or notepad! You think I wanted my code kicked all over the place in multiple folders and files? No.
So back to Pascal. I made some apps for my old hobby, was quite satisfied with the result (quiz like app), but it still wasn't the thing. And I really thought I'd like to study CS.
I started to love PHP because of phpBB forums I worked on as 15 y.o. I guess. At the same time I think there was an optional subject at school, again with Pascal. I hated the subject, teacher spoke some kind of gibberish I didn't really understand back then at all and now I find it only as a really stupid explanation of loops and strings.
So I started to hate Pascal subject, but not really the lang itself. Still I wanted something simpler and more portable. Then I got to Python as hm, 17y.o. I think and at the same time to C++ with DevC++. That was time when I was still deciding which lang to choose as my main one (still playing with website, database and js).
Then I decided that learning language from some teacher in a class seriously pisses me off and I don't want to experience it again. I choose Python, but still made some little scripts in C++, which is funny, because Python was considered only as a scripting lang back then.
I haven't really find a cross-platform framework for C++, which would: a) be easy to install b) not require VisualStudio PayForMe 20xy c) have nice license if I managed to make something nice and distribute it. I found Unity3D though, so I played with Blender for models, Audacity for music and C# for code. Only beautiful memories with Unity. I still haven't thought I'm a programmer back then.
For Python however I found Kivy and I was playing with it on a phone for about a year. Still I haven't really know what to do back then, so I thought... I like math, numbers, coding, but I want to avoid studying physics. Economics here I go!
Now I'm in my third year at Uni, should be writing thesis, study hard and what I do? Code like never before, contribute, work on a 3D tutorial and play with Blender. Still I don't really think about myself as a programmer, rather hobby-coder.
So, to answer the question: how did I learn to program? Bashing to shit until it behaved like I desired i.e. try-fail learning. I wouldn't choose a different path.2 -
It was around for a while but I didn’t realize it was it for a long time. I was fixing computers for cash and spending in on booze while in primary school. Making websites for cash and for fun while in high school. Some guys wanted to buy my databases at the time and sending me emails that my websites rocks. I didn’t cared cause I party a lot and I didn’t need money.
Sex drugs and rock and roll was my life not a fucking computer.
Since I never had problems with math I passed exams and got myself to university and dropped out cause of those 3 funny things above. Turned out to pass exams after second year when math and physics disappeared you need to study more then 1 day before exam and party was more important for me.
I failed tremendously. My girlfriend left me I was out of money I got back to my hometown with my laptop and I somehow between depression, drugs, alcohol and killing myself reminded I was getting money from websites and I can try to follow that movie.
At that time I didn’t read single book in english in my life. I know some basic english so I decided to try to read some actionscript2 pdf. Why actionscript ? I liked those simple games. Those were fun and there was nothing better. I was reading first book at least 10 times with vocabulary that took about a month until I remembered whole book and second book was faster like 1 week third was 1 day and from then thing moved a little faster. I discovered flex just before adobe acquired macromedia and started writing in it. Started answering to some questions on forum and build some portfolio website with fancy 3d animations and stuff and finally applied for 2 jobs.
They both were amazed by my website and one of them sent me some task to do and I did it overnight and sent them back. They wanted to hire me and I need to respond to them.
Second job they invited me for talking and asking about math, if I’m ok with 3d and stuff and they offered me job closer to my home town so I picked them. The code was amazing, 3d equations, quaternions, complicated stuff bit very well written by some company that dropped project before launch and my first task was add some small feature.
I remember first day in elevator with my former boss who told me to not to get scary and take it slowly I was trying to do my task as fast as I can worried I will be fired if I don’t do it and nobody else will hire me and I won’t manage to recover from second failure. It was even more fighting with myself that I will fail again then with this task lol.
I’ve done the feature third day and when they said it’s cool and I can commit my changes it appeared to me that It might be this shit that will get me out of trouble.
I was never again wrong about programming and so wrong about trouble but that’s a different story... -
Recently I completed a whole year in programming. Holy jebus, I have no idea I could make it through.
I started thinking I was "decent" at this because I had taken a half dozen courses in python plus some algorithm logic in school lol @ innocent me
I'm an applied math student and I hereby declare I was the most incompetent dude you'll ever see.
I've been through so much shit I didn't realize I had a shitty boss, because one would think it's normal for a beginner to approach everything in programming because I was told to do so. Full blown restful apis, stateful redux react apps with responsive CSS using Google's material design. Don't forget to dockerize everything and deploy the swarm on Amazon cloud all the while having to run integration unit tests, make sure all the rules on your nginx are correct we don't want exposure do you know how to write a visualization tool on JavaScript so we can 3d-fy some x-ray prints and good luck balancing tight schedules with your school and girlfriend ye right lul
My manager would ask me to deliver new shit to an app I was developing mostly by my self in react (I barely even knew what RFC or ES6 was by the time I started).
I got fired from this project because I couldn't deliver by myself what 5 experienced dudes could (debatable, but still... Cuz they couldn't when they took over. Boss wanted to rewrite the whole app in a week and a half)
Turns out I got called back by the same company but to contribute in another project. This time to automate some shizzle with python.
Feelsgoodman but I want out ASAP can't stay sane for longer
