Example: s = "Hello" # s is a string Then we find out something about s. Lets begin: So you want to know what is the class of s at run time? irb(main):055:0* s.class => String Ohh, good. But what are the methods of s? irb(main):002:0> s.methods => [:unicode_normalize,...

1. What is MVVM? The Model View ViewModel (MVVM) pattern is a design pattern most commonly used for creating user interfaces. It is derived from the the popular "Model View Controller" (MVC) pattern. The major advantage of MVVM is that it separates: The internal representation of the a...

Docker is supported on the following 64-bit versions of Ubuntu Linux: Ubuntu Xenial 16.04 (LTS) Ubuntu Wily 15.10 Ubuntu Trusty 14.04 (LTS) Ubuntu Precise 12.04 (LTS) A couple of notes: The following instructions involve installation using Docker packages only, and this ensures obtaining...

Haskell Wiki has an example of a non-parametric parameter of a type function: type family Inspect x type instance Inspect Age = Int type instance Inspect Int = Bool Here x is non-parametric because to determine the outcome of applying Inspect to a type argument, the type function must insp...

An example of a parametric parameter of a type function: data List a = Nil | Cons a (List a) type family DoNotInspect x type instance DoNotInspect x = List x Here x is parametric because to determine the outcome of applying DoNotInspect to a type argument, the type function do not need to in...

A phantom type parameter has a phantom role. Phantom roles cannot be declared explicitly.

The example I'm going to discuss assumes you have a Docker installation that works in your system and a basic understanding of how to work with Node.js . If you are aware of how you must work with Docker , it should be evident that Node.js framework need not be installed on your system, rather we wo...

The typical usage is with CSV-type files, where each line consists of fields separated by a delimiter, specified by the option -d. The default delimiter is the TAB character. Suppose you have a data file data.txt with lines like 0 0 755 1482941948.8024 102 33 4755 1240562224.3205 1003 1 644 12199...

You cannot have more than one delimiter: if you specify something like -d ",;:", some implementations will use only the first character as a delimiter (in this case, the comma.) Other implementations (e.g. GNU cut) will give you an error message. $ cut -d ",;:" -f2 <<<&...

$ cut -d, -f1,3 <<<"a,,b,c,d,e" a,b is rather obvious, but with space-delimited strings it might be less obvious to some $ cut -d ' ' -f1,3 <<<"a b c d e" a b cut cannot be used to parse arguments as the shell and other programs do.
