Here's a list of numbers that pass the lund test and everything, so they validate for the different card types. Of course they're dummy accounts, so only use them while your gateway is in test mode.

test credit card numbers

I've been adding a bunch of features to a JSP application I wrote a while back. It's very reassuring to look at Java code and know that you don't have to worry about side effects, scoping problems, libraries called in from some obscure place in the code, etc.



But boy do I hate comparisons like this:



while(i++ < ((Integer)hashFromDb.get("integerColumn")){...}

I installed swift-generator on my shared domain account at Dreamhost.com and set up a demo here.



Swift-generator lets you merge dynamic data with Flash movies. In this case, you can place some text onto a colored circle. This doesn't fully demonstrate the possibilities, but stay tuned, as I have a couple projects coming up that will use this technology.

Here I go, moving scripts from one server to another. Perl scripts with a MySQL backend running on linux to another linux server with mysql. Decent scripts... should be a piece of cake.



I'm always fascinated with the way other developers structure their code. How they think about the task at hand, what they choose to make central and what problems they end up solving as they come because they didn't forsee them. (I hope nobody's looking at my old code!)



Especially when the basic problem to solve is "how do you take info in a database, display it in a form, and save the changes back to the database". I've solved this myself in at least three fundamentally different ways, and I've run into at least a double handfull of other approaches. And counting!

Helped a website update their Authorize.net integration. It was an ADC Relay Response done several years ago and finally stopped working, though there was an interim where it wouldn't recognize failed transactions and instead sent out the service weather the credit card transaction worked or not.



I also enhanced the original integration by adding the x_Color_Background, x_Color_Link, x_Color_Text and x_Logo_URL hidden form fields.



If you care, here's the functional reference from Authorize.net.

I'm figuring out the details on a web package to pull classified ads from one website into a portal, allow people to respond to the classified ad, refer the response to the originating site, and track the whole thing for revenue sharing purposes.
