Debug your PHP code efficiently with a variety of client and server-side tools. In this concise course for experienced PHP developers, author Jon Peck demonstrates how to leverage PHP's built-in tools, as well as the Xdebug and Firebug extensions, and FirePHP libraries to improve the quality of your code and reduce troubleshooting overhead. This course covers installation of Xdebug on Apache as well as working with the NetBeans IDE (integrated development environment). Jon then introduces native web browser developer tools for Firefox and Chrome, and demonstrates browser independent web debugging tools. Best practices for debugging and profiling web application failures and performance issues are also covered.
Learn new concepts, patterns, and methods that will expand your programming abilities, helping move you from a novice to an expert programmer. This course assumes previous programming experience, comparable to what is covered by the Udacity CS101 course. Move along the path towards becoming an expert programmer! In this class you will practice going from a problem description to a solution, using a series of assignments.
In this course you will examine real world problems -- rescue the Apollo 13 astronauts, stop the spread of epidemics, and fight forest fires -- involving differential equations and figure out how to solve them using numerical methods. You'll need a basic knowledge of programming for this course, around the level of CS 101 or equivalent. You'll also need to understand trigonometry at the high school level, as well as basic vector algebra. This class will primarily involve solving equations numerically rather than analytically, but some exposure to calculus and physics at the level of PH 100 wouldn't hurt. By the end of this course, you'll develop an intuition for the use of differential equations in the applied sciences. You'll also learn how to build mathematical models for systems of differential equations. Along the way, you'll learn how to translate mathematical expressions into Python code, and solve some really cool problems!
