Data Analysis Basics: Making Decisions with Data
Learn how to make better decisions with data in this course on data analysis. We'll start by looking at what data analysis is, and then we'll see how we can use data analysis to create better outcomes.
Build a Chatbot with Watson APIs
IBM has created an AI platform named Watson that gives businesses and developers access to powerful tools for text and speech analysis, computer vision, and more. Watson APIs consist of a suite of services used to process or analyze data to answer questions and make decisions. This course will show you how to build a chatbot with Node.js and the Conversation and Discovery services from Watson. You'll also learn how to setup and deploy your bot on IBM's Bluemix platform.
Using CSS Variables
Learn how to use native CSS variables to make your stylesheets less repetitive, easier to maintain and more.Viewed
Introduction to Application Security
Welcome to the realm of web security, where millions of dollars and people’s lives are on the line. Well, not in all cases, but some! From protecting static web sites to the most complex of web services and APIs, every web developer should be aware of and adept at writing secure code and building systems that can stand up to the strongest of malicious users. In this course, we will lay the groundwork for what you need to know to get started exploring the vast field of web security, and along the way you will begin to realize that security isn’t about checking boxes, but rather about embedding the thought process and principles of rock-solid security into every line of code you write. First, we will discuss why security matters to you as a web developer, then we will look at data security at an implementation level, then finally we will examine the art of maintaining your websites, apps, and services on a daily basis.

Creating and Modifying Database Tables
Learn how to create and modify your own database tables as we work through a real-life example! We'll talk about how to choose the right structure for a database and then see how we can implement that structure.
Introduction to Data Visualization with Matplotlib
Get started creating charts with the Python library, matplotlib, an industry standard data visualization library. Matplotlib provides a way to easily generate a wide variety of plots and charts in a few lines of Python code. It is an open source project that can be integrated into Python scripts, jupyter notebooks, web application servers, and multiple GUI toolkits. Whether you are exploring sample data available on the internet, or your own business data, learning matplotlib is a great place to start your data visualization journey.

Cleaning and Preparing Data
We rely on data to answer important questions, whether we are trying to make the best business decisions or determine the effectiveness of a new medical treatment. But our analyses are only as accurate as the data we are using, and incorrect or “dirty” data can lead to incorrect conclusions and assumptions. Data preparation, also called “cleaning” or “scrubbing”, is an important part of ensuring our analyses are accurate and useful.
Saving Data on a Server
So far all our networking code could do was make GET requests but being able to send and save data to a server is just as important. In this course, let's improve our networking code and learn how to make a POST request. There are a lot of additional concerns when saving data and we'll spend some time talking about security, preventing malicious input and much more.
Unit Testing in iOS
Unit testing allows you to test your application for logic errors, prevent crashes, and even write better code. In this course, we cover the philosophy behind unit testing, ways we can structure our code to make it more testable and look at tools we can use to test our code. We'll look at both tools that come built in, like the XCTest Framework in Xcode, as well as a few third party solutions for both Objective-C and Swift.
