A revised SCORM API wrapper

I’ve been a longtime user of the ADL wrapper (with code from the late Claude Ostyn), and to be honest, it’s pretty much met my needs. But I was never completely comfortable with the wrapper for two reasons: 1) The code is hard to read with confusing and overly complicated looking variable names, and 2) the code made heavy use of global variables, which in this Web 2.0 world is a big no-no. This past week I decided to roll up my sleeves and make a new SCORM API wrapper that takes care of these issues.

LMSs are just websites… no, really!

Folks, it’s simple — if you have to paste a “this site works best with XXX browser” message on your site, whether it’s an LMS, an online course, or just a website for your mom’s knitting club, you’re doing something wrong. Do us a favor and stop it.

Assistive computer technology and web accessibility

Just thought I’d pass this link on: http://www.assistiveware.com/videos.php (short write-up here — thanks to Roger Johansson for the link.)

These are video profiles of people with disabilities — mild to severe — who use assistive computer technology to improve their lives. Some people use the computers to simply help them with their jobs (such as a blind person who is a professional French-to-English translator), while others use their computers as a lifeline to the rest of the world.

Armed with a basic understanding of accessibility, and with a little planning, a web developer can create courses and/or websites that contain rich content — even Flash movies and videos — while supporting a majority of assistive computer/alternative web browsing technologies.

ActionScript, JavaScript, and SCORM

For the last week, I’ve been doggedly attempting to create a hybrid of Flash-to-JavaScript communication techniques for creating cross-browser SCORM-conformant courses that work with almost any version of Flash Player. Today I threw in the towel. Here’s my story.

Email address obfuscation

Everyone knows the story: an innocent email address is posted online and a big bad spambot finds it, relaying it to every spammer on the face of the earth… the email address becomes useless due to the 500 spam emails you get every day!

Vertical centering — without using tables!

Every now and then, a developer will come up against something that was SOOOO easy with table-based layouts and winds up being a royal pain with CSS-based layouts. One of these “d’oh!” moments is when you try to vertically center an element on your web page. Umm… hang on, let me rephrase that: One of these “d’oh!” moments is when you try to vertically center an element on your web page when using Internet Explorer 6.

Online XML-to-XSD Converter

This week I needed to create an XML Schema doc for work. The XSD file would be used to validate XML files I’ll be making for my online courses. Well, being a newbie to XSD files (though not XML), I was making decent but very slow progress when a thought occurred to me: it should be possible to reverse-engineer an XML file to create an XSD file.
