• Real-time spectrum analyzer with API

  - by bobobobo

  I'm looking for a C or C++ API that will give me real-time spectrum analysis of a waveform on Windows. I'm not entirely sure how large a sample window it should need to determine frequency content, but the smaller the better. For example, if it can work with a 0.5 second long sample and determine frequency content to the Hz, that would be wicked-awesome.

• Why did my ASP.NET Web App stop showing AM in times?

  - by qntmfred

  I haven't made any code or configuration changes (that I know of) to my ASP.NET web application and this morning it suddenly stopped showing the AM in my displayed times. PM still shows up, just not AM. It's hosted on Windows Server 2003. I figured somehow the OS regional settings might have been changed somehow, but that doesn't appear to be the case. How could this have happened?

• Use Case diagrams as a requirements gathering tool for new functionality - particularly in systems t

  - by drelihan

  Hi Folks I'm interested in persuing the idea of using Use Case Diagrams as a tool for collecting user requirements. However, it will be for new features as opposed to developing a system from scratch. Also, the system only has a small level of user interaction - most of the actors will be external systems. I want to know what people's experiances have been with using this method of gathering requirements. How did your customers respond to the change and was it positive? Did it just not work for anybody? Thanks,

• Java: Calculate distance between a large number of locations and performance
