What happens when maxing out Postgres' work_mem?
Date : March 29 2020, 07:55 AM
around this issue PostgreSQL will for example switch to a sorting operation more suitable for on-disk sort than in-memory sort if it knows the sort will happen on disk - which it won't know if it happens in swap. Also, PostgreSQL can switch to a completely different plan (for example, using a different JOIN method) if it figures out the data does not fit in RAM.

Maxing out on $digest iterations
Date : March 29 2020, 07:55 AM
To fix this issue This is because it is is creating a brand new object every time it goes through the digest cycle. Watches are registered in this = databinding, and so every time it evaluates bar="{baz: 3}" a new object is created, and so it will be different from the previous value, trigerring another digest loop. Eventually it aborts so that it doesn't loop infinitely. See http://docs.angularjs.org/guide/concepts#runtime for a more thorough explanation. The trick is to do the = databing with a reference that won't be changing every time. This is usually done by having it in the scope outside the directive. See http://jsfiddle.net/u4BTu/7/

C# UDP Server loop maxing CPU
Tag : chash , By : user183275

should help you out Adding Thread.Sleep(1) call to the update loop fixed not only the CPU usage in the original problem, but it also made the the code executed in the update loop behave better. inside the while(alive)}{ } where I keep track of the elapsed time and total time, I insert the sleep call. The value seems to be needed at least 1. static void Main(string[] args)
{
//Initialize
Console.Title = "Pong Server";
Console.WriteLine("Pong Server");
serverSocket = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp);
//Bind socket
EndPoint localEndPoint = new IPEndPoint(IPAddress.Any, 25565);
Console.WriteLine("Binding to port 25565");
serverSocket.Bind(localEndPoint);
//Listen
Console.WriteLine("Listening on {0}.", localEndPoint);
//Prepare EndPoints
EndPoint clientEndPoint = new IPEndPoint(IPAddress.Any, 0);
//Recive Data...
serverSocket.BeginReceiveFrom(rcvPacket, 0, Data.Size, SocketFlags.None, ref clientEndPoint, new AsyncCallback(ReceiveFrom), null);
//Initialize TimeSpans
DateTime Now = DateTime.Now;
DateTime Start = Now;
DateTime LastUpdate = Now;
TimeSpan EllapsedTime;
TimeSpan TotalTime;
//Create Physics Objects
Paddle1 = new Physics2D();
Paddle2 = new Physics2D();
Ball = new Physics2D();
//Loop
while (alive)
{
Now = DateTime.Now;
TotalTime = Now - Start;
EllapsedTime = Now - LastUpdate;
LastUpdate = Now;
Update(EllapsedTime, TotalTime);
//Add Sleep to reduce CPU usage;
Thread.Sleep(1);
}
//Press Any Key
Console.WriteLine("Press any key to exit.");
Console.ReadKey();
}
