Sliding window algorithm is used to perform required operation on specific window size of given large buffer or array. Window starts from the 1st element and keeps shifting right by one element. The objective is to find the minimum k numbers present in each window. This is commonly know as Sliding w...

public class SlidingWindow { public static int[] MaxSlidingWindow(int[] input, int k) { int[] result = new int[input.Length - k + 1]; for (int i = 0; i <= input.Length - k; i++) { var max = input[i]; for (int j = 1; j < k; j++) ...

Out of the box installations of Jenkins with the Git and SSH plugins will not work when attempting to pull a private repository from GitHub.

The first step to fix this issue I found was to download PSTools and extract the tools to a convenient location on the build server (e.g. c:\Programs\PSTools is there I extracted mine).

The hard part is over! Now just create the credentials to be used in Jenkins. Use your own Username and the passphrase used to create the SSH Key. This is what it should look like now (with your own private github repo and user name:

Save and run a test pull request and your should no longer have any further problems with having Jenkins use SSH on your Windows build machine.

The Maya GUI toolkit creates a variety of UI elements in a simple, imperative form. There are basic commands to create and edit GUI widgets; the widgets are identified by a unique string name. All gui commands take the same basic form: you supply a command type and the string name of the object yo...

A C program that wishes to accept network connections (act as a "server") should first create a socket bound to the address "INADDR_ANY" and call listen on it. Then, it can call accept on the server socket to block until a client connects. //Create the server socket int servsoc...

Even when sockets are in "blocking" mode, the read and write operations on them do not necessarily read and write all the data available to be read or written. In order to write an entire buffer into a socket, or read a known quantity of data from a socket, they must be called in a loop. ...

Many widgets include events which can fire callback functions when the user interacts with the widget. For example when a button is pressed, a checkbox checked, or a dropdown chosen you can fire a function. The exact flag which is associated with these event depends on the widget, but a typical cal...

This small example shows how you can lose backward compatibility in your programs if you do not take care in advance about this. And ways to get more control of serialization process At first, we will write an example of the first version of the program: Version 1 [Serializable] class Data { ...
