In this C++ code, sorting the data (before the timed region) makes the primary loop ~6x faster: #include <algorithm> #include <ctime> #include <iostream> int main() { // Generate data const unsigned arraySize = 32768; int data[arraySize]; for (unsigned c = 0; c < arraySize; ++c) data[c] = std::rand() % 256; // !!! With this, the next loop runs faster. std::sort(data, data + arraySize); // Test clo
I have to build a tree that will contain about 300 nodes inside it. The tree has no depth limitations. So it can have 3 or 15 levels. Each node can have an unlimited number of children. The priority is to get a complete tree / subtree the faster as possible, but I also need to add nodes or move nodes sometimes but not that often. I want to know the best way to store the tree in the database and th
Does anyone know how to configure the jetty gradle plugin to run in debug mode so that I can attach a remote debugger?

How do I return the response/result from a function foo that makes an asynchronous request? I am trying to return the value from the callback, as well as assigning the result to a local variable inside the function and returning that one, but none of those ways actually return the response — they all return undefined or whatever the initial value of the variable result is. Example of an asynchrono
I hate asking such a vague question, but I'm having a hard time finding a simple example. Here's what I have so far: public class JettyWebSocketServlet extends WebSocketServlet{ @Override public void configure(WebSocketServletFactory factory) { factory.register(MyEchoSocket.class); } } @WebSocket public class MyEchoSocket { @OnWebSocketMessage public void onText(WebSocketConnection conn, String me
You can dynamically request icon images from the Google charts api with the urls: http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FE7569 Which looks like this: the image is 21x34 pixels and the pin tip is at position (10, 34) And you'll also want a separate shadow image (so that it doesn't overlap nearby icons): http://chart.apis.google.com/chart?chst=d_map_pin_shadow Which
