I used to share business/application ideas privately with my business partner Jason through email. We would send emails to one another with a subject line like “BIG IDEA” and the body would be a short 1-2 paragraph description of the idea.

It was always bitter sweet when we’d see something implemented a year or two later that we had the idea for. “We thought of that!”

Anyway, I’m going to start posting some of my wacky ideas publicly on here. Not many read this.. and I rarely try to implement them anyway… might as well have a place I can point to that says “See, I thought of that.”

First of all, there’s nothing new about MarylandMVA.com’s registration renewal. I’ve been using it for years. The look and feel is ancient, but it gets the job done. What I came across today really drove me nuts.

The first step of the renewal process asks you to input your 8 digit vehicle registration number. I get 4 digits in and accidentally mistype. I hit the backspace key, nothing happens. I hit another number… it gets added to my input. Backspace, nothing happens.

Knowing a little about web applications I decided to dig in to see what was going on. The developers of this page wrote a validation function for the registration input:

function validateTitle(field, e) {
	var strCheck = '0123456789ABCDEFGHIJKLMNOPQRSTUVWZXYZabcdefghijklmnopqrstuvwxyz';
	var whichCode = (window.Event) ? e.which : e.keyCode;

	if (whichCode == 13) return true;  // Enter
	key = String.fromCharCode(whichCode);  // Get key value from key code
	//alert(strCheck.indexOf(key));
	if (strCheck.indexOf(key) == -1) return false;  // Not a valid key
}

This function is called each time you press a key on the keyboard while typing in your registration number. It’s a common approach to form validation. The basics are: you hit a key, if it’s the Enter Key, a number or a letter, the character is permitted to be added to the form input. Anything else, the keystroke is denied.

To be fair, there was a warning on the main page that recommended using Internet Explorer. I tried this form in Internet Explorer and the backspace key behaves correctly. My immediate thought was “What about Mac users?” To my surprise, Safari also allows you to backspace without any problem!

The code above should specifically reject any key other than enter, a number, or A-Z. It appears that Safari’s engine Webkit was changed in 2007 to match Internet Explorer — the Backspace key does not trigger a “keypress” event. Firefox does fire a keypress for the backspace key and will therefore prevent you from correcting your mistake on the MVA form.

AFAIK, there’s nothing in the HTML spec that states whether a backspace (or arrow key, etc) should fire the onkeypress event. Should Firefox also try to “closely match Internet Explorer” with this behavior? Or should sites like the MarylandMVA be encouraged to update their sites to support modern/common browsers?

I’ve been dealing with a lot of bugs in Wordabble as we’ve been beta testing the next release. Even after I published the release (yesterday) a few minor bugs have been discovered. That can be terribly frustrating… so when I stumbled across this video today it really put a smile on my face. A user of the new Tiger Woods PGA game had discovered a scenario where you could get Tiger to walk on water.

EA put together a brilliant response. It’s not just the “BLAH, we had a bug, so what” response that all developers love to give… they’ve turned it into a viral marketing spot. They can’t release an update to the game to fix this kind of thing, so their bug fix is to actually make Tiger Woods walk on water.

Absolutely brilliant!

I came across a poster today that I’m considering. I wouldn’t even try to find this signed by the actor … there’s no way it would be affordable.

Isn’t it creepy? He really played a good Joker. I wonder how many Jokers we’ll see this year at Halloween. Probably too many.

That’s right — there appears to be a little cow in that hatchback.
