Free Springer Books during COVID19

Free Springer Books during COVID19

Book publisher Springer just released over 400 book titles that can be downloaded free of charge following the corona-virus outbreak.

Here’s fhe full overview: https://link.springer.com/search?facet-content-type=%22Book%22&package=mat-covid19_textbooks&facet-language=%22En%22&sortOrder=newestFirst&showAll=true

Most of these books will normally set you back about $50 to $150, so this is a great deal!

There are many titles on computer science, programming, business, psychology, and here are some specific titles that might interest my readership:

Note that I only got to page 8 of 21, so there are many more free interesting titles out there!

CodeWars: Learn programming through test-driven development

CodeWars: Learn programming through test-driven development

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!

Python, Ruby, C++, Java, JavaScript and many other main programming languages are already supported, but CodeWards is also still developing kata for more niche or upcoming languages like R, Lua, Kotlin, and Scala.

Anomaly Detection Resources

Anomaly Detection Resources

Carnegie Mellon PhD student Yue Zhao collects this great Github repository of anomaly detection resources: https://github.com/yzhao062/anomaly-detection-resources

The repository consists of tools for multiple languages (R, Python, Matlab, Java) and resources in the form of:

  1. Books & Academic Papers
  2. Online Courses and Videos
  3. Outlier Datasets
  4. Algorithms and Applications
  5. Open-source and Commercial Libraries/Toolkits
  6. Key Conferences & Journals

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.

Object-Oriented Programming with Java

Object-Oriented Programming with Java

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.

Now, I personally won’t start on learning Java anytime soon. Hence, I am just sharing this pearl of a resource with a wider audience right now. This MOOC by the university of Helsinki has been in my inbox for quite a while: Object-Oriented Programming with Java. If you understand Finnish, you can even take the 2019 Finnish version of the course.

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!

Learn Programming Project-Based: Build-Your-Own-X

Last week, this interesting reddit thread was filled with overviews for cool projects that may help you learn a programming language. The top entries are:

There’s a wide range of projects you can get started on building:

Daily Art by Saskia Freeke

Daily Art by Saskia Freeke

Saskia Freeke (twitter) is a Dutch artist, creative coder, interaction designer, visual designer, and educator working from Amsterdam. She has been creating an awesome digital art piece for every day since January 1st 2015. Her ever-growing collection includes some animated, visual masterpieces.

My personal favorites are Saskia’s moving works, her GIFs:

Saskia uses Processing to create her art. Processing is a Java-based language, also used often by Daniel Shiffmann whom we know from the Coding Train.
