About Derek Banas

Once a day I post a link to an original video & tutorial on communication, web development, dieting, marketing, hypnosis, etc. For Free!

I used to work for Apple and Morgan Stanley. My ultimate goal is to help unemployed people easily add to their skill set so they can get a job for free.

Perl 6 Tutorial

This tutorial is a 400 page Perl 6 tutorial condensed down into 1 video. Perl 6 is a get it done fast utility language. I’d say it is the most popular utility language. The newest version ads a ton of tools to the original Perl. I cover Data Types, Conditionals, Strings, Interpolation, Looping, Arrays,...

LaTeX Tutorial

LaTeX is the most popular typesetting system and in this video I condense down a 400 page book on LaTeX into 1, 1 hour video. I also have condensed down all that information into a free cheat sheet. LaTeX is used to create most of the technical and scientific papers that you will ever see. It can be used to...

Install Fortran Windows

In this video I show how to install the following on Windows : Fortran, NetBeans, MinGW, C and C++. I then show you how to test the installation and setup environment variables. I also teach Fortran in one video here.  This is the best Fortran book I have found. More learn in one videos are coming until...

Fortran Tutorial

In this one video I condense most everything you’d learn about Fortran in a 400 page book into one video. I cover User Input, Variables, Data Types, Print, Formatted Output, Math Operators, Random Numbers, Math Functions, Conditionals, If / Else, Select, Looping, While, Cycle, Exit, Arrays, Format,...

MATLAB Tutorial

In this tutorial I cover basically everything you’d learn in a 500 page book on MATLAB in a video that is just over 1 hour! So many topics are covered, but this is an abbreviated list : Input, Data Types, Casting, Math Functions, Conditionals, Vectors, Matrices, Looping, Cell Arrays, Strings,...

Julia Tutorial

Here is a 300 Page book on Julia in a 1 hour video. Julia is a fast, general purpose language that can easily integrate with libraries from numerous languages and has numerous libraries that are of interest especially to mathematically inclined people. All of the code and a transcript of the video follows...

Learn Crystal in One Video

Crystal is one of the most exciting new languages to come out in some time, so I decided to teach the core language in one video. Crystal is as easy to use as Ruby, but has the speed of C. In this one video I’ll cover Data Types, Strings, Arrays, Map, Looping, Conditionals, Math, Hashes, Tuples, Procs,...

Arduino 11 Finish Pong

In this video I finish creating Pong on an LCD Panel with an Arduino. I combine the code for making the Paddles work, with the code for making the ball bounce. We mainly have to consolidate printing to the LCD panel, while making sure we don’t have any character number conflicts. If you made this...

Arduino 10 : Arduino Pong 2

As we continue making Pong with an Arduino, I now create the code to make the ball handle collision detection, movement and way much more. We are building Pong on a constrained piece of hardware using raw binary bits and clever algorithms. Like before I’ll live code everything with very little...

Arduino 9 Arduino Pong

Someone requested that I make the game Pong on a 16 x 2 LCD panel and so I start doing that in this tutorial. I’m going to live code everything with no preparation ahead of time, so that you can see how I solve this problem. I focus this time on drawing on the LCD panel, moving the paddles and...
