Since the Physical Address Extension (PAE) mode that was introduced in the Pentium Pro (and Pentum M) was such a change to the Operating System memory management subsystem, when Intel designed the Pentium II they decided to enhance the "normal" Page mode to support the new Physical Address...

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...

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...

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....

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...

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; ...

If you're doing multiple long calculations, you can run them at the same time on different threads on your computer. To do this, we make a new Thread and have it point to a different method. using System.Threading; class MainClass { static void Main() { var thread = new Thread(Seco...

Sometimes, you want your threads to simultaneously share data. When this happens it is important to be aware of the code and lock any parts that could go wrong. A simple example of two threads counting is shown below. Here is some dangerous (incorrect) code: using System.Threading; class MainCl...

Given a file using ; as a column delimiter. Permuting the first and the second column is accomplished by awk -F';' -v 'OFS=;' '{ swap = $2; $2 = $1; $1 = swap; print }'

Given a file using ; as a column delimiter. We compute the median of the values in the second column with the following program, written for GNU awk. The provided input is the list of grades of a student group: gawk -F';' '{ sample[NR] = $2 } END { asort(sample); if(NR % 2 == 1) { p...

There are two main ways to create an axes in matplotlib: using pyplot, or using the object-oriented API. Using pyplot: import matplotlib.pyplot as plt ax = plt.subplot(3, 2, 1) # 3 rows, 2 columns, the first subplot Using the object-oriented API: import matplotlib.pyplot as plt fig = ...

Unlike Java, Dart doesn’t have the keywords public, protected, and private. If an identifier starts with an underscore _, it’s private to its library. If you for example have class A in a separate library file (eg, other.dart), such as: library other; class A { int _private = 0; testA()...

There are 2 ways of instantiating prefabs: during design time or runtime. Design time instantiation Instantiating prefabs at design time is useful to visually place multiple instances of the same object (e.g. placing trees when designing a level of your game). To visually instantiate a prefab...

You can use gradle to have BuildConfig constants and res values on a per flavor basis. Just add the value to the flavor you want to support. android { defaultConfig { resValue "string", "app_name", "Full App" buildConfigField "boolean",...

To change PS1, you just have to change the value of PS1 shell variable. The value can be set in ~/.bashrc or /etc/bashrc file, depending on the distro. PS1 can be changed to any plain text like: PS1="hello " Besides the plain text, a number of backslash-escaped special characters are s...

By default CakePHP loads the related model in the controller. In order to load another model in the controller, use the loadModel() method: $this->loadModel('Articles'); or load on the fly $table = TableRegistry::get('Articles'); $table->find();

To translate strings, you will have to create translation files. To do so, django ships with the management command makemessages. $ django-admin makemessages -l fr processing locale fr The above command will discover all strings marked as translatable within your installed apps and create one l...

The sensor values returned by Android are with respective to the phone's coordinate system (e.g. +Y points towards the top of the phone). We can transform these sensor values into a world coordinate system (e.g. +Y points towards magnetic North, tangential to the ground) using the sensor managers ro...

Hex Opacity Values ------------------------------ | Alpha(%) | Hex Value | ------------------------------ | 100% | FF | | 95% | F2 | | 90% | E6 | | 85% | D9 | | 80% | ...
