All 4 version are valid, but they exemplify different aspects of a reduction. By default, the first construct using the reduction clause must be preferred. This is only if some issues are explicitly identified that any of the 3 alternatives might be explored.

When To Use BigInteger objects are by their very nature very heavy on RAM. Consequently, they should only be used when absolutely necessary, ie for numbers on a truly astronomical scale. Further to this, all arithmetic operations on these objects are an order of magnitude slower than their pri...

Promises have state, they start as pending and can settle to: fulfilled meaning that the computation completed successfully. rejected meaning that the computation failed. Promise returning functions should never throw, they should return rejections instead. Throwing from a promise returnin...

async-await allows asynchronous (means non-blocking, parallel) execution of code. It helps to keep your UI responsive at all times, while running potentially long operations in the background. It is especially useful for I/O operations (like downloading from a server, or reading a file from the H...

// Calling: variable.member_function(); variable_pointer->member_function(); // Definition: ret_type class_name::member_function() cv-qualifiers { body; } // Prototype: class class_name { virt-specifier ret_type member_function() cv-qualifiers virt-speci...

These are two sample programs that work together. One is a simple server, the other a simple client. Start the server in one window: python tserver.py Edit the server address in the client source file if desired. Then run python tclient.py The client connects to the server, then asks for i...

This section provides an overview of what pthreads is, and why a developer might want to use it. It should also mention any large subjects within pthreads, and link out to the related topics. Since the Documentation for pthreads is new, you may need to create initial versions of those related to...

Headless mode in Unity If you are building a Server to deploy in Linux, the Build settings have a "Headless mode" option. An application build with this option doesn't display anything and doesn't read user input, which is usually what we want for a Server.

Sqoop incremental import comes into picture because of a phenomenon called CDC i.e. Change Data Capture. Now what is CDC? CDC is a design pattern that captures individual data changes instead of dealing with the entire data. Instead of dumping our entire database, using CDC, we could capture ju...

Node.js uses streams to handle incoming data. Quoting from the docs, A stream is an abstract interface for working with streaming data in Node.js. The stream module provides a base API that makes it easy to build objects that implement the stream interface. To handle in request body of a PO...

While an Erlang string is a list of integers, an "iolist" is a list whose elements are either integers, binaries or other iolists, e.g. ["foo", $b, $a, $r, <<"baz">>]. That iolist represents the string "foobarbaz". While you can convert an iolist ...

The value null is the default value for an uninitialized value of a field whose type is a reference type. NullPointerException (or NPE) is the exception that is thrown when you attempt to perform an inappropriate operation on the null object reference. Such operations include: calling an inst...

Step definitions are in the programming language supported by a given implementation of Cucumber. This topic gives examples of step definitions in each supported programming language and examples of using Cucumber API calls in step definitions.
