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...

The X-macro approach can be generalized a bit by making the name of the "X" macro an argument of the master macro. This has the advantages of helping to avoid macro name collisions and of allowing use of a general-purpose macro as the "X" macro. As always with X macros, the mas...

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...

docker run docker/whalesay cowsay 'Hello, StackExchange!' This command tells Docker to create a container from the docker/whalesay image and run the command cowsay 'Hello, StackExchange!' in it. It should print a picture of a whale saying Hello, StackExchange! to your terminal. If the entrypoin...

INSERT INTO Customers (FName, LName, PhoneNumber) SELECT FName, LName, PhoneNumber FROM Employees This example will insert all Employees into the Customers table. Since the two tables have different fields and you don't want to move all the fields over, you need to set which fields to insert int...

Reflection is often used as part of software testing, such as for the runtime creation/instantiation of mock objects. It's also great for inspecting the state of an object at any given point in time. Here's an example of using Reflection in a unit test to verify a protected class member contains the...

The first two arguments to format are an output stream and a control string. Basic use does not require additional arguments. Passing t as the stream writes to *standard-output*. > (format t "Basic Message") Basic Message nil That expression will write Basic Message to standard ou...

By default, containers created with docker run are given a random name like small_roentgen or modest_dubinsky. These names aren't particularly helpful in identifying the purpose of a container. It is possible to supply a name for the container by passing the --name command line option: docker run -...

main = do input <- getContents putStr input Input: This is an example sentence. And this one is, too! Output: This is an example sentence. And this one is, too! Note: This program will actually print parts of the output before all of the input has been fully read in. This m...

main = do line <- getLine putStrLn line Input: This is an example. Output: This is an example.

Like in several other parts of the I/O library, functions that implicitly use a standard stream have a counterpart in System.IO that performs the same job, but with an extra parameter at the left, of type Handle, that represents the stream being handled. For instance, getLine :: IO String has a cou...

During a merge, you can pass --ours or --theirs to git checkout to take all changes for a file from one side or the other of a merge. $ git checkout --ours -- file1.txt # Use our version of file1, delete all their changes $ git checkout --theirs -- file2.txt # Use their version of file2, delete ...

To stop a running container: docker stop <container> [<container>...] This will send the main process in the container a SIGTERM, followed by a SIGKILL if it doesn't stop within the grace period. The name of each container is printed as it stops. To start a container which is stoppe...

Ordinarily, images are pulled automatically from Docker Hub. Docker will attempt to pull any image from Docker Hub that doesn't already exist on the Docker host. For example, using docker run ubuntu when the ubuntu image is not already on the Docker host will cause Docker to initiate a pull of the l...

You can assign an image to a UIImageView during initialization, or later using the image property: //Swift UIImageView(image: UIImage(named: "image1")) UIImageView(image: UIImage(named: "image1"), highlightedImage: UIImage(named: "image2")) imageView.image = UII...

You can animate a UIImageView by quickly displaying images on it in a sequence using the UIImageView's animation properties: imageView.animationImages = [UIImage(named: "image1")!, UIImage(named: "image2")!, UIImage(nam...

It's an emulation of classical inheritance using prototypical inheritance which shows how powerful prototypes are. It was made to make the language more attractive to programmers coming from other languages. 6 IMPORTANT NOTE: Since ES6 it doesn't make sense to use pseudo-calssical inheritance sinc...

5 Treat a property as a combination of two functions, one to get the value from it, and another one to set the value in it. The get property of the property descriptor is a function that will be called to retrieve the value from the property. The set property is also a function, it will be call...
