  • Where should we manage session objects in an ASP.NET application?

    - by Kumar
    I am developing a 3-tired ASP.NET C# web application and was wondering where should the sessions be managed. I have a SessionManager class as follows: public sealed class SessionManager { private const string USER = "User"; private SessionManager() { } public static SessionManager Instance { get { return _instance; } } public User User { get { return HttpContext.Current.Session[USER] as User; } set { HttpContext.Current.Session[USER] = value; } } } Now should the session information be managed in the Business Logic Layer or should it be managed in the Presentation Layer?

  • Scaling range of values with negative numbers

    - by Pradeep Kumar
    How can I scale a set of values to fit a new range if they include negative numbers? For example, I have a set of numbers (-10, -9, 1, 4, 10) which have to scaled to a range [0 1], such that -10 maps to 0, and 10 maps to 1. The regular method for an arbitrary number 'x' would be: (x - from_min) * (to_max - to_min) / (from_max - from_min) + to_min but this does not work for negative numbers. Any help is appreciated. Thanks!!
