writing code today isn't quite like it used to be...

Some handy resources out there for software development, and google will get you in touch with them...I've never coded on puchcards, or relied on books for helping me code on projects, however I would like to appreciate those circumstances.

I usually manage projects, clients, and focus my time and energy on business development tasks. It wasn't that long ago, that I actually had to code..like, every day. That was a great time, and an important part of the progression of Nerdy Dragon.

How to format a javascript variable as currency:

function formatCurrency(num) {
num = num.toString().replace(/\$|\,/g, '');
if (isNaN(num)) num = "0";
sign = (num == (num = Math.abs(num)));
num = Math.floor(num * 100 + 0.50000000001);
cents = num % 100;
num = Math.floor(num / 100).toString();
if (cents < 10) cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)
num = num.substring(0, num.length - (4 * i + 3)) + ',' + num.substring(num.length - (4 * i + 3));
return (((sign) ? '' : '-') + '$' + num + '.' + cents);
}

If you're writing a calculator, the above 2 javascript functions could come in quite handy :)

some EXPLAINING and tuning of MySQL - big data requires resources to work with. The less work you ask the database to do, the less you'll need to spend on those resources.

It's good to be developing software today, and even better to share the tools, methods, and experiences.
