Some applications may want to create so-called "Fire & Forget" tasks which can be periodically triggered and do not need to return any type of value returned upon completion of the assigned task (for example, purging old temp files, rotating logs, autosaving state).
In this example, w...

Instancing can be done via modifications to how vertex attributes are provided to the vertex shader. This introduces a new way of accessing attribute arrays, allowing them to provide per-instance data that looks like a regular attribute.
A single instance represents one object or group of vert...
Here are the steps to generate test skeleton for existing code:

The Iris flower data set is a widely used data set for demonstration purposes. We will load it, inspect it and slightly modify it for later use.

ZeroR is a simple classifier. It doesn't operate per instance instead it operates on general distribution of the classes. It selects the class with the largest a priori probability. It is not a good classifier in the sense that it doesn't use any information in the candidate, but it is often used as...
In order to build a good classifier we will often need to get an idea of how the data is structered in feature space. Weka offers a visualisation module that can help.
Some dimensions already seperate the classes quite well. Petal-width orders the concept quite neatly, when compared to petal-widt...
Trees can build models that work on independent features and on second order effects. So they might be good candidates for this domain. Trees are rules that are chaind together, a rule splits instances that arrive at a rule in subgroups, that pass to the rules under the rule.
Tree Learners generate...

It is often necessary to execute a long-running task and use the result of that task once it has completed.
In this example, we will create two classes: One which implements the Callable<T> interface (where T is the type we wish to return), and one which contains a main() method.
AsyncValueT...

The S in S.O.L.I.D stands for Single responsibility principle(SRP).
Responsibility means in this context reasons to change, so the principle states that a class should only have one reason to change.
Robert C. Martin stated it (during his lecture at Yale shool of management in 10 Sep 2014) as foll...
Step 1 - Include the uiGrid in your project

Eventloop in pseudo code
An event loop is a loop that waits for events and then reacts to those events
while true:
wait for something to happen
react to whatever happened
Example of a single-threaded HTTP server with no event loop
while true:
socket = wait for the next TCP c...

pre-push script is called by git push after it has checked the remote status, but before anything has been pushed. If this script exits with a non-zero status nothing will be pushed.
This hook is called with the following parameters:

It is possible to create own Linux distribution using Yocto Project.
For Raspberry Pi- there is a specific layer meta-raspberrypi that needs to be used to create an image.
Windows 10 IoT Core is available only for Raspberry Pi 2 and 3. It is important to note that this is not a full version of windows as one might expect, it is designed specifically for IoT (Internet of Things) applications. It will not run most standard windows applications, and does not have a start...
