Binary for Babies

You can study computer science at any age! :-)

VWD Course

Visual Web Development (VWD) is a course I taught at the University of Eastern Finland. In it, we study algorithms by implementing and visualizing them in the browser. We use HTML5 Canvas and vanilla JavaScript to make: interactive applications, image processing, machine learning and games. We limit the use of external libraries so that we understand how things really work.

Master Skier

I give cross country skiing advice to beginners (especially suitable for foreign students in Finland). I play the 'Master Skier' character, a character obsessed with skiing, because I think it adds humor to otherwise bland informational videos. The 'Master Skier' persona was inspired by Davie504 and his passion for Bass. In more recent videos the Master Skier broke his leg (I broke my leg...) so the videos are less about skiing and more about developing the character. He meets the Magic Man, Batman and collects the Dragonballs!

Coding Interview Parodies

Coding interview parody sketches where Mr. Mariescu applies for the same job over and over again. I really hope you have better luck :-))

Walk and Talk

A series where I summarize the advice I give to my students.

Coding Ultramarathon

I coded live, non-stop for 24 hours and managed to make 76 projects using vanilla JavaScript and HTML5 canvas. YouTube didn't like me streaming for so long so I had to divide the video into 3 parts and reupload.

Chain Coding Challenge

Frank from Frank's laboratory and I take turns coding and see what we come up with!

Web of Motivation

I explain a technique I developed to stay Motivated! It is related to the idea of dividing objectives into smaller goals but not exactly that. Check it out!

Cooking Codes

Cooking recipes are algorithms. Don't believe me? Watch this!

My Kamehameha

I really wanted to do a Kamehameha! So, I got in shape by doing intense exercise for 3 months and coded a Kamehameha visual and sound effect using vanilla JavaScript and HTML canvas.

Learn Machine Learning

We learn how machine learning works by building a web app (HTML and JavaScript) that can recognize objects when shown to the camera. We implement the app without using any external libraries so that we really understand how machine learning works.

Every-Crane Series

The origami crane can be made from almost anything! Don't believe me? Watch this!

My PhD defence

Pythagorean Theorem

The Pythagorean Theorem is one of the most useful things in the world! In this video, I teach what it is, I show different proofs, applications and how to implement it in JavaScript.

Melody Maker

I teach how to synthesize sounds in JavaScript using the Web Audio API and how to make an app for learning music. In the app, you add notes on a stave listen to the melody.

Santa and his Penguins

Game developed with pupils from Joensuun normaalikoulu. Game is still under development and crazy things are expected to come soon enough! Keep an eye out for my 'Magic of Code' live streams if you want to see the updates!

Draw the Portal

Game inspired by Doctor Strange from the Marvel cinematic universe. You need to draw a free-form shape in front of the camera. The rounder it is, the higher the score!

Coronaville

Game teaching about the easy spread of the new Coronavirus.

HackeRacer

Game teaching you to type code fast!

Levels of Code

Funny sketch showing the different levels coders are able to reach. An homage to Dragonball where we see what what would happen if Programmers could go Super Saiyan :-)

Voice Kamehameha

We build an app that uses the camera and microphone to generate a Kamehameha.
You'll need to show something blue (preferably wrist bands ;-)) and speak into a microphone.

Matrix Effect on Shirt

I teach you how to code the matrix rain effect on a blue shirt. It's kind of a blue-screen effect, but not exactly that!

Self-driving car

You will learn to make a self-driving car simulation by implementing every component one by one. I will teach you how to implement the car driving mechanics, how to define the environment, how to simulate some sensors, how to detect collisions and how to make the car control itself using a neural network. I will explain how artificial neural networks work, by comparing them with the real neural networks in our brain. I will teach you how to implement a neural network and how to visualize it so we can see it in action. You will also learn some optimization techniques to make our car smarter. The entire system is quite complex, however, each component is relatively easy in and of itself. I made this course keeping in mind my high-school days back in Romania. So, the knowledge you get from school could be enough to follow along (depending on the curriculum).
