WE DID IT!
Together, we reached 1.5k members!
Compared to other huge channels it's a small number, but to me it is a lot.
Thank you for those who gave me support, thank you to those who actively read my posts and maybe even solved a few challenges, Thank you to those who recommended me to friends, Thank you to the websites featuring my channel.

I hereby want to mention, that you could help me a lot by doing one of those three things:
1) Send me an idea for a programming challenge
2) Give me ideas on how to improve the quality of this challenge
3) Point out subtle mistakes
4) Recommend this channel to your friends.

Why code?
=============
ITS SUNDAY, ffs, you should let your mind rest.
Your task: meditate for half an hour. Close your eyes, focus on your breathing, try to hold your breath, maybe even try to fall asleep.


Oohh and: turn off all your devices

Flappy bird
=========
Implement flappy birds but with a catch! the bird moves from top to bottom instead of from left to right

Quick maths
===============
Find a way to calculate wether two circles touch.
the only things you know:
1) radius circle one
2) xy circle one
3) radius circle two
4) xy circle two

Pattern converter
)==========(
Take in an image and convert it to ascii art. Bonus points if you can add color!

Do you think that you have learned enough? Once you are good enough, challenges are not enough to become good. If you want to become a web-developer, get a bit of help from @thefrontend

Scareeeeehhhhh
==========
Make a program that finds the best times to wake someone up with spooky noise. It should be based on studies on sleep, to make it extra spooky

Pattern recognition
=======
Find a way to recognize the mood in the picture.
Sadness, anger etc

Surface
========
Given N polygons, can you calculate the surface of the shape?
If you are on a Rush: do it with N = 3

Skill to learn
================
Suggestion: learn music theory! It will help you appreciate classical music and will give you a counterpoint to programming!

📖 What could we improve on in the future?
Be honest!

👤 delet chanel pls now

👤 Add time estimation

👤 Promote me to admin! I can improve the channel.

👤 Hello

👤 Tell time limits and other restrictions like ,,size of executable must not exceed 64kB"

👤 Shorter challenges. We usually have 1-2 hour / day for challenges, not 23 😒

👤 Shorter challenges

👤 after the challenges send us the answers and many of the challenges needs good description so you need to work on that

👤 Shorter challenges

👤 hello

👤 easy medium hard and extreme challenges and (some of)challenge should be based fully on real life situations

👤 Easy,medium,hard and extreme challenges and (some of)challenge should be based fully on real life situations.

👤 Suggestions:write the difficulty, the approximate time .we need some fubar challenges . Keep up the good work 😊

👤 Post results in the mean time. Some of us get wrong codes.

👤 After the challenges send us the answers

SOCATOA
difficulty: easy
time: 15 minutes
programming language: any
help: https://en.wikipedia.org/wiki/Trigonometric_functions
++++++++++++++++++++++++++
Implement the two trigonometric functions sin() and cos(). If you have time, you can also add tan() and cot().

FRACTALS
difficulty: easy
time: 25 - 45 minutes
programming language: Js with p5.js or processing or python
========================
Implement a menger-sponge fractal and display it. Optimize the simulation as well as you can!

Fourier Transform
difficulty: hard
time: 3-10 h
programming language: any
======================
Take a vibration (=> sound) and find a way to sequence it into separate (sine-)vibrations.
This is called a fourier transform and is very useful!
++++++++++++++++++++++++
