Note that when compiling with sbt package, the .jar will now be created in target/scala-2.11/, and the .jar name will al...
ML Transformers now generates org.apache.spark.ml.linalg.VectorUDT instead of org.apache.spark.mllib.linalg.VectorUDT.
They are also mapped locally to subclasses of org.apache.spark.ml.linalg.Vector. These are not compatible with old MLLib API which is moving towards deprecation in Spark 2.0.0.

The Firebase auth system is the source of a users uid, displayName, photoURL, and maybe email. Password based accounts set these persistent values in the auth system via the .updateProfile method. Storing these values in the Realtime Database, rDB, users node poses the issue of stale data. Displa...

This custom UserControl will appear as a regular combobox, but unlike the built-in ComboBox object, it can show the user a default string of text if they have not made a selection yet.
In order to accomplish this, our UserControl will be made up of two Controls. Obviously we need an actual ComboBox...
Let we assume we have two databases "ORA1" and "ORA2". We can access the objects of "ORA2" from database "ORA1" using a database link.
Prerequisites:
For creating a private Database link you need a CREATE DATABASE LINK privilege.

QML came with rich set of visual elements. Using only QML we can build complex applications with these elements.
Also it's very easy to build your own element based on set of standard items like Rectangle, Button, Image etc.

Create horizontal lines with a label. This could be used to show notable values in the chart data (e.g. min, max, average). JSFiddle Demo
var horizonalLinePlugin = {
afterDraw: function(chartInstance) {
var yScale = chartInstance.scales["y-axis-0"];
var canvas = chartInstance...
Denormalization and a flat database structure is neccessary to efficiently download separate calls. With the following structure, it is also possible to maintain two-way relationships. The disadvantage of this approach is, that you always need to update the data in multiple places.
For an example, ...
[TestCase(0, 0, 0)]
[TestCase(34, 25, 59)]
[TestCase(-1250, 10000, 8750)]
public void AddNumbersTest(int a, int b, int expected)
{
// Act
int result = a + b;
// Assert
Assert.That(result, Is.EqualTo(expected));

A DataFrame is a distributed collection of data organized into named columns. It is conceptually equivalent to a table in a relational database. DataFrames can be constructed from a wide array of sources such as: structured data files, tables in Hive, external databases, or existing RDDs.
