alternatives to codecademy Running my software company from 2009 to 2011 without a development background was challenging to say the least. It is how I became involved with GirlDevelopIt (an organization offers programming classes for women) and why I started LearnRuby101. With this post, my goal is to share the free interactive learn-how-to-code sites I’ve come across that can help you get started. I’ve also gathered the top recommended books on each language from Hacker News.

Loading images and Library assets with ActionScript 3 While the previous example is simple and functional (and you can continue to create new Loader object instances each time you add an external image), there are other, more robust strategies you can use. Creating Loader objects that are more flexible and efficient requires a thorough understanding of the loading process. Within the Loader object instance, the bitmap data from the referenced image is placed within a Bitmap object. Loader objects load images as bitmap data, but then place the data in a Bitmap object (again, a Bitmap object references a BitmapData object). The Bitmap object instance is the content (child) of the Loader object instance. The hierarchy for this structure looks like this: Loader object > Bitmap object > BitmapData object.

Using jQuery for Background Image Animations After reading Dave Shea's article on CSS Sprites using jQuery to produce animation effects, I felt like playing around with things to see what could be done but accomplish it with a simpler HTML structure (no need for adding superfluous tags) and simpler code, too. Changing the position of the background image felt to be the best approach to creating the type of effect we're looking for (and I'm not the first to think so: see the examples at the end of this article). jQuery is a great library for this type of task but out of the box, it can't animate background position properly because of the need to animate two values instead of just one (too bad not all browsers implemented the non-standard background-position-x and -y like Internet Explorer).

PHP Login script tutorial We have a login form in step 2, when a user submit their username and password, PHP code in checklogin.php will check that this user exist in our database or not. If user has the right username and password, then the code will register username and password in the session and redirect to "login_success.php". If username or password is wrong the system will show "Wrong Username or Password".

Use and Performance of the Timer Class in ActionScript 3 and Flash One of the new classes introduced in ActionScript 3 is the Timer class. The class, in essence, replaces the AS2 setInterval and clearInterval functions. (Those functions are still present but deprecated in AS3.) In this How-To, we show a simple example of using the Timer class and discuss briefly performance issues related to the Timer class. Download

Tips Page Sorry, no technical support is available for my tips and techniques Please report any web-related problems by sending an email to the address listed below. Sorry for the inconvenience, but I will not have the chance to respond to questions relating to these tutorials. For immediate response to your issues and questions, check out the Adobe Forum: 27 Ways to Learn to Program Online Whether you are looking to switch careers and become a full-time programmer, want to try to build a website or app on the side, or are just looking to round out your skill set, learning to code has certainly been something a lot of people have started to do lately. And while being a programmer might not be for everyone, there is a lot to be said about gaining a better, more educated view of how all those pixels get moved around all those screens. Before we delve into our list of learning resources sites, we wanted to share some advice from Marissa Louie, a self-taught product designer for Ness Computing. A former startup founder, Louie told TNW that the hardest part of being self-taught – whether it’s design, programming, or any other discipline is, “gathering the courage. The most important barrier is just to overcome your fears” (she also said having the ability to follow instructions helps as well).
