   • In computer science, what is a server?

     Top Answer

     Answered Jul 20, 2016 · 1 votes

     A server is a computer that provides data to other computers. It may serve data to systems on a local area network (LAN) or a wide area network (WAN) over the Internet.

     Many types of servers exist, including web servers, mail servers, and file servers. Each type runs software specific to the purpose of the server. For example, a Web server may run Apache HTTP Server or Microsoft IIS, which both provide access to websites over the Internet. A mail server may run a program like Exim or iMail, which provides SMTP services for sending and receiving email. A file server might use Samba or the operating system's built-in file sharing services to share files over a network.

   • Bug in Delphi 2009? -> *.res not found in project search path (works in Delphi 2006)

     Top Answer

     Answered Jun 10, 2017 · 2 votes

     A workaround is to put this in your code in stead:

     {$R res\test.res}-

     That works on my system with Delphi 2009, both with the IDE and the command-line compiler.

     Note that I agree that they broke existing functionality, did you add a report to Quality Portal? If not, please do: ttps://quality.embarcadero.com (this used to be the search engine indexed http://qc.embarcadero.com but that has been shut down; https://quality.embarcadero.com requires a free account to search).

   • Bug in MVC3 - requests never time out. Works fine for aspx pages in same project

     Top Answer

     Answered Aug 30, 2011 · 8 votes

     I found the cause for this, methinks:

     This method is in the WrappedAsyncResult class, which the MvcHandler class uses via BeginProcessRequest:

     public static IAsyncResult BeginSynchronous<TResult>(AsyncCallback callback, object state, Func<TResult> func, object tag){ BeginInvokeDelegate beginDelegate = delegate (AsyncCallback asyncCallback, object asyncState) { SimpleAsyncResult result = new SimpleAsyncResult(asyncState); result.MarkCompleted(true, asyncCallback); return result; }; EndInvokeDelegate<TResult> endDelegate = _ => func(); WrappedAsyncResult<TResult> result = new WrappedAsyncResult<TResult>(beginDelegate, endDelegate, tag); result.Begin(callback, state, -1); return result;}

     where "Begin" is:

     public void Begin(AsyncCallback callback, object state, int timeout){ bool completedSynchronously; this._originalCallback = callback; lock (this._beginDelegateLockObj) { this._innerAsyncResult = this._beginDelegate(new AsyncCallback(this.HandleAsynchronousCompletion), state); completedSynchronously = this._innerAsyncResult.CompletedSynchronously; if (!completedSynchronously && (timeout > -1)) { this.CreateTimer(timeout); } } if (completedSynchronously && (callback != null)) { callback(this); }}

     EDIT: have come up with a ham-handed way of forcing MVC controller actions to "time out", although the mechanism is a bit brutish:

     public class TimeoutController : Controller{ private bool _isExecuting = false; private int _controllerTimeout = 5000; private Thread _executingThread; private readonly object _syncRoot = new object(); protected override void ExecuteCore() { _executingThread = Thread.CurrentThread; ThreadPool.QueueUserWorkItem(o => { Thread.Sleep(_controllerTimeout); if (_isExecuting) { _executingThread.Abort(); } }); base.ExecuteCore(); } protected override void OnActionExecuting(ActionExecutingContext filterContext) { _isExecuting = true; base.OnActionExecuting(filterContext); } protected override void OnActionExecuted(ActionExecutedContext filterContext) { _isExecuting = false; base.OnActionExecuted(filterContext); } public int ControllerTimeout { get { int retVal; lock(_syncRoot) { retVal = _controllerTimeout; } return retVal; } set { lock(_syncRoot) { _controllerTimeout = value; } } }}

   • Bug in the 0-1 Knapsack code. What is the error in my code?

     Top Answer

     Answered Feb 24, 2020 · 0 votes

     For one, you have separate N and W lengths, which is redundant as these should always be equal. I think the problem you are observing, though, is with your else if. You check if the current weight is less than the number of items, which doesn't really make sense. It should probably be something like else if(j-wt[i]>=0), since you are trying to determine if you can subtract the current weight wt[i] from the current sum j and get a valid (in bounds) result. I imagine you are getting a segfault or similar because you are trying to access dyna[i-1][j-wt[i]] when, for instance, i and j are 1 and wt[i] is 10, as dyna[0][-9] is (probably) unalloced memory.
