Meteor.wrapAsync(func, [context]) ParametersDetailsfunc: FunctionAn asynchronous/synchronous function to be wrapped in a Fiber that takes a callback w/ parameters (error, result).context: Any (optional)A data context in which the function gets executed upon. An asynchronously wrapped funct...

Linq queries are written using the Standard Query Operators (which are a set of extension methods that operates mainly on objects of type IEnumerable<T> and IQueryable<T>) or using Query Expressions (which at compile time, are converted to Standard Query Operator method calls). Query ...

methoddetailsSoftwareSerial.hDocumentationSoftwareSerial(rxPin, txPin, inverse_logic)Constructor. rxPin: Data in (receive) pin, defaults to 0. txPin: Data out (transmit) pin, defaults to 1. inverse_logic: If true, treats LOW as if it were HIGH and HIGH as LOW when determining bit values. defaults t...

Bit shift operations are not portable across all processor architectures, different processors can have different bit-widths. In other words, if you wrote int a = ~0; int b = a << 1; This value would be different on a 64 bit machine vs. on a 32 bit machine, or from an x86 based processo...

Python, being one of the most popular languages in computer and network security, has great potential in security and cryptography. This topic deals with the cryptographic features and implementations in Python from its uses in computer and network security to hashing and encryption/decryption algor...

Please play with these concepts yourself to really master them! The elm-repl (see the Introduction to the REPL) is probably a good place to play around with the code above. You can also play with elm-repl online.

A Singleton is designed to ensure a class only has one instance and provides a global point of access to it. If you only require one instance or a convenient global point of access, but not both, consider other options before turning to the singleton. Global variables can make it harder to reason...

In most cases, the spread operator *. is identical to calling .collect { it.________ }. def animals = ['cat', 'dog', 'fish'] assert animals*.length() == animals.collect { it.length() } But if the subject is null, they behave a differently: def animals = null assert animals*.length() == null...
