The Open Source Society University offers a complete education in computer science using online materials.
According to their GitHub page, the curriculum is suited for people with the discipline, will, and good habits to obtain this education largely on their own, but who’d still like support from a worldwide community of fellow learners.
Intro CS: for students to try out CS and see if it’s right for them
Core CS: corresponds roughly to the first three years of a computer science curriculum, taking classes that all majors would be required to take
Advanced CS: corresponds roughly to the final year of a computer science curriculum, taking electives according to the student’s interests
Final Project: a project for students to validate, consolidate, and display their knowledge, to be evaluated by their peers worldwide
Pro CS: graduate-level specializations students can elect to take after completing the above curriculum if they want to maximize their chances of getting a good job
It is possible to finish Core CS within about 2 years if you plan carefully and devote roughly 18-22 hours/week to your studies. Courses in Core CS should be taken linearly if possible, but since a perfectly linear progression is rarely possible, each class’s prerequisites are specified so that you can design a logical but non-linear progression based on the class schedules and your own life plans.
As I wrote about Project Euler and CodingGame before, someone recommended me CodeWars. CodeWars offers free online learning exercises to develop your programming skills through fun daily challenges.
In line with Project Euler, you are tasked with solving increasingly complex programming challenges. At CodeWars, these little problems you need to solve with code are called kata.
Kata take a test-driven development approach: the programs you write need to pass the tests of the developer who made the kata in the first place. Only then are you awarded with honour and can you earn your ranks and progress to the more complex kata.
Sounds fun right? I’m definitely going to check this out, as they support a wide range of programming languages, each with many kata to solve!
The repository consists of tools for multiple languages (R, Python, Matlab, Java) and resources in the form of:
Books & Academic Papers
Online Courses and Videos
Algorithms and Applications
Open-source and Commercial Libraries/Toolkits

Outlier Detection (also known as Anomaly Detection) is an exciting yet challenging field, which aims to identify outlying objects that are deviant from the general data distribution. Outlier detection has been proven critical in many fields, such as credit card fraud analytics, network intrusion detection, and mechanical unit defect detection.
A friend of mine pointed me to this great website where you can interactively practice and learn new programming skills by working through small coding challenges, like making a game.
Now that I’m slowly familiarizing myself in the world of Python, I am much more often confronted with classes and object-oriented programming (OOP). While R has its own OOP paradigms (yes, multiple, obviously, it’s R after all), I have never experienced the need to create my own classes. However, in other languages, like Python, Ruby, or Java, OOP is much more an essential of developers’ and programmers’ skillsets.
During this course you will learn all the basics of computer programming, algorithms and object-oriented programming using the Java programming language. The course includes comprehensive course materials and plenty of programming exercises, each tested using our automatic testing service Test My Code.
Part 1 of the course will teach you all the basics of the Java language:
Part 2 continues with some more advanced topics:
While I have not taken the course myself yet, I have read a lot of good reviews about it. Moreover, what better way to learn a new language than by deep diving into it with a specialized topic like OOP. And it’s free! And taught by trained academics! What are you still doing here, start learning!
