How I Started in Web Development
·
Every now and again, someone asks me how I got started in web development. They want to know what classes I took in college. What my degree is in. Who I studied under. It’s not a big secret, so I’ll tell you.

JavaScript Astrophysics
·
As computers continue to develop and grow, so do the things they’re capable of; just about any laptop capable of playing FarmVille can also run a sophisticated astrophysics simulation. In college, it took me a few minutes with a room-sized supercomputer to derive the Chandrasekhar Limit. The same derivation can now run in JavaScript, embedded…

The Hackiest Hack that Ever Was Hacked
·
I was first introduced to Plupload when I was building websites in .Net. I had some great HTML5 file upload tools that worked wonders in my browser of choice, but most of my colleagues (and about 80% of our clients) were using a browser that didn’t support the API. I used Plupload as a reliable…

Don’t Dequeue WordPress’ jQuery
·
As a moderator on the WordPress Stack Exchange, I end up spending a lot of time on the site.

It worked, but why reinvent the wheel? It turns out jQuery is perfectly capable of serving as a global event bus for all of your…

The Anatomy of an Exploit
·
I’m a huge fan of security. I spend many a weekend experimenting with new encryption techniques, hash algorithms, and security protocols. As a result, I also come across several different server exploits in the wild. PHP hacks, [cci].htaccess[/cci] hacks, JavaScript injection, etc. I once even saw a server hacked through a corrupt PNG image that…

Object-Oriented JavaScript
·
First a caveat: JavaScript is a prototype-based language, not an object-oriented language. Now that we have an understanding of that very important fact, let’s learn how to use JavaScript as if it were object-oriented. A few weeks ago, I was asked to teach a couple of my colleagues how to code with JavaScript. We’re building…

JavaScript Event Bus
·
I was taught some time ago to always focus on decoupling my code. Your server and the client (browser) should not need to know anything about the structure of one another. They can pass information back and forth, but that should be the full extent of their integration. There are several reasons for this, but…
