I'm writting a financial C# application which receive messages from the network, translate them into different object according to the message type and finaly apply the application business logic on them.

I noticed a new web service today called a Dead man's switch, which dispatches email in the event that you don't respond to periodic "pings" that prove you're still alive. But it occurred to me that I might outlive the person or organization that pays the bills for the service, making the service useless. There are other kinds of servic...
I am a programmer at a financial institute. I have recently been told to enforce that all new user id's to have at least one alpha and one numeric. I immediately thought that this was a horrible idea and I would rather not implement it, as I believe this is an anti-feature and of poor user experience. The problem is that I don't have ...

I write financial applications where I constantly battle the decision to use a double vs using a decimal. All of my math works on numbers with no more than 5 decimal places and are not larger than ~100,000. I have a feeling that all of these can be represented as doubles anyways without rounding error, but have never been sure. I would...

What is the most recommended free/public API for accessing financial market stats and stock quotes (preferrably real-time quotes)? I'm not too picky about how it's exposed (SOAP, REST, some proprietary XML setup, etc.), as long as it's got some decent documentation. I'm planning to build a simple web dashboard in PHP with some basic dat...

Are there any studies on the impact of websites in general or well-designed websites for businesses? By well-designed, I mean highly functional, accessible, and usable websites - along the lines of Section 508 compliance. A quick Google search didn't seem to turn up anything too useful, so I thought I would appeal to the SO community for...
I have a program that downloads basic historical stock data from yahoo and puts it into an SQLite database. I'd like to be able to perform queries such as finding the moving average, and determining the longest period where a stock has either continued to go up or down. I could write perl functions to do this but this seems like overkill...
