Branching in Subversion is very simple. In the simplest form, creating a new branch requires you to run the command against the remote repository's URLs. For example, let's create a new branch out of the mainline trunk: svn copy https://svn.example.com/svn/MyRepo/MyProject/trunk https://svn.example...

When you interact with the remote central repository using your private local workspace -- the working copy -- you can use repository-relative URL instead of direct URL to URL copy to create a new branch: svn copy "^/MyProject/trunk" "^/MyProject/branches/MyNewBranch" -m "C...

Before publishing a package you have to version it. npm supports semantic versioning, this means there are patch, minor and major releases. For example, if your package is at version 1.2.3 to change version you have to: patch release: npm version patch => 1.2.4 minor release: npm version min...

for (x <- 1 to 10) println("Iteration number " + x) This demonstrates iterating a variable, x, from 1 to 10 and doing something with that value. The return type of this for comprehension is Unit.

This demonstrates a filter on a for-loop, and the use of yield to create a 'sequence comprehension': for ( x <- 1 to 10 if x % 2 == 0) yield x The output for this is: scala.collection.immutable.IndexedSeq[Int] = Vector(2, 4, 6, 8, 10) A for comprehension is useful when you need to crea...

git cherry-pick <commit-hash> will apply the changes made in an existing commit to another branch, while recording a new commit. Essentially, you can copy commits from branch to branch. Given the following tree (Source) dd2e86 - 946992 - 9143a9 - a6fd86 - 5a6057 [master] \ ...

The background-image property is used to specify a background image to be applied to all matched elements. By default, this image is tiled to cover the entire element, excluding margin. .myClass { background-image: url('/path/to/image.jpg'); } To use multiple images as background-image, defi...

A CLOS class is described by: a name a list of superclasses a list of slots further options like documentation Each slot has: a name an initialization form (optional) an initialization argument (optional) a type (optional) a documentation string (optional) accessor, reader and/or wr...

Go is a statically typed language, meaning you generally have to declare the type of the variables you are using. // Basic variable declaration. Declares a variable of type specified on the right. // The variable is initialized to the zero value of the respective type. var x int var s string va...

In Go, you can declare multiple variables at the same time. // You can declare multiple variables of the same type in one line var a, b, c string var d, e string = "Hello", "world!" // You can also use short declaration to assign multiple variables x, y, z := 1, 2, 3 ...

Using the Java-SDK 3.0.1 CountDownLatch lock = new CountDownLatch(1); SpeechToText service = new SpeechToText(); service.setUsernameAndPassword("<username>", "<password>"); FileInputStream audio = new FileInputStream("filename.wav"); RecognizeOpti...

This example shows how to use the IBM Watson Speech to Text service to recognize the type of an audio file and produce a transcription of the spoken text in that file. This example requires Speech to Text service credentials and Node.js Install the npm module for the Watson Developer Cloud N...

There are three ways of creating a new branch feature which tracks the remote branch origin/feature: git checkout --track -b feature origin/feature, git checkout -t origin/feature, git checkout feature - assuming that there is no local feature branch and there is only one remote with the featur...

Characters for bulleted lists: * Asterisks + Plus signs - Minus signs Characters for bulleted lists: Asterisks Plus signs Minus signs Please note: For the best results you have to use the same character because as you can see in the example below different signs make the list ...

Creating an empty table is as simple as this: local empty_table = {} You can also create a table in the form of a simple array: local numeric_table = { "Eve", "Jim", "Peter" } -- numeric_table[1] is automatically "Eve", numeric_table[2] is "Ji...

A database snapshot is a read-only, static view of a SQL Server database (the source database). It is similar to backup, but it is available as any other database so client can query snapshot database. CREATE DATABASE MyDatabase_morning -- name of the snapshot ON ( NAME=MyDatabase_data, -- l...

If data in a source database becomes damaged or some wrong data is written into database, in some cases, reverting the database to a database snapshot that predates the damage might be an appropriate alternative to restoring the database from a backup. RESTORE DATABASE MYDATABASE FROM DATABASE_SNAP...

Here's the 'bare minimum' Arduino sketch. This can be loaded into the Arduino IDE by choosing File > Examples > 01. Basics > Bare Minimum. void setup() { // put your setup code here, to run once } void loop() { // put your main code here, to run repeatedly } Code in the setup...

Here's a short example that demonstrates the setup() and loop() functions. This can be loaded into the Arduino IDE by choosing File > Examples > 01. Basics > Blink. (Note: Most Arduino boards have an LED already connected to pin 13, but you may need to add an external LED to see the effects...

In this example we will write a basic program that checks the number of inputs and outputs passed to a MEX-function. As a starting point, we need to create a C++ file implementing the "MEX gateway". This is the function executed when the file is called from MATLAB. testinputs.cpp // Mat...
