public class IntStack { private IntStackNode head; // IntStackNode is the inner class of the class IntStack // Each instance of this inner class functions as one link in the // Overall stack that it helps to represent private static class IntStackNode { privat...

When creating a nested class, you face a choice of having that nested class static: public class OuterClass1 { private static class StaticNestedClass { } } Or non-static: public class OuterClass2 { private class NestedClass { } } At its core, static nested c...

A full explanation of Access Modifiers in Java can be found here. But how do they interact with Inner classes? public, as usual, gives unrestricted access to any scope able to access the type. public class OuterClass { public class InnerClass { public int x = 5; } p...

This topic is intended for intermediate to advanced F# developers "What are Monads?" is a common question. This is easy to answer but like in Hitchhikers guide to galaxy we realize we don't understand the answer because we didn't know what we were asking after. Many believe the way to un...

To create a prefab, drag a game object from the scene hierarchy into the Assets folder or subfolder: The game object name turns blue, indicating it is connected to a prefab. Now this object is a prefab instance, just like an object instance of a class. A prefab can be deleted after instanti...

:mak[e][!] [arguments] will start the program referred to by the makeprg option. By default, makeprg is set to "make," but can be configured to invoke any appropriate program. All [arguments] (can be several) are passed to makeprg just as if it had been invoked with :!{makeprg} [arguments...

Note that many datatypes don't need to be quoted, since they evaluate to themselves. QUOTE is especially useful for symbols and lists, to prevent evaluation as Lisp forms. Example for other datatypes not needed to be quoted to prevent evaluation: strings, numbers, characters, CLOS objects, ... Her...

For sending and receiving events we first need an Event object. Event objects are actually simple POJOs. public class ArbitaryEvent{ public static final int TYPE_1 = 1; public static final int TYPE_2 = 2; private int eventType; public ArbitaryEvent(int eventType){ this....

For receiving events you need to register your class on the EventBus. @Override public void onStart() { super.onStart(); EventBus.getDefault().register(this); } @Override public void onStop() { EventBus.getDefault().unregister(this); super.onStop(); } And then subscribe ...

Sending events is as easy as creating the Event object and then posting it. EventBus.getDefault().post(new ArbitaryEvent(ArbitaryEvent.TYPE_1));

Declared variable without a value will have the value undefined var a; console.log(a); // logs: undefined Trying to retrieve the value of undeclared variables results in a ReferenceError. However, both the type of undeclared and unitialized variables is "undefined": var a; console...

A patch is a file that show the differences between two revisions or between your local repository and the last revision your repository is pointing. To share or save a patch of your local uncommitted changes either for peer review or to apply later, do: svn diff > new-feature.patch To get a...

Running svn log will show you all the commit messages, you probably want to review only certain revisions. View the n most recent revisions: svn log -n View a specific revision: svn log -c rXXX View the paths affected: svn log -v -c rXXX

The key in vectorizing R code, is to reduce or eliminate "by row operations" or method dispatching of R functions. That means that when approaching a problem that at first glance requires "by row operations", such as calculating the means of each row, one needs to ask themselves...

C99 These functions returns the floating-point remainder of the division of x/y. The returned value has the same sign as x. Single Precision: #include <math.h> /* for fmodf() */ #include <stdio.h> /* for printf() */ int main(void) { float x = 10.0; float y = 5.1; ...

function transform(fn, arr) { let result = []; for (let el of arr) { result.push(fn(el)); // We push the result of the transformed item to result } return result; } console.log(transform(x => x * 2, [1,2,3,4])); // [2, 4, 6, 8] As you can see, our transform fun...
