When is a language considered a scripting language? [closed]
Simple. When I use it, it’s a modern dynamic language, when you use it, it’s merely a scripting language!

Exactly what is a “third party”? (And who are the first and second party?)
If you are developing software for a client, then there is a contract between you/your company, and the client/their company. These are the two parties to the contract. Anyone else, not bound by the contract, is a third party. It’s used wherever a contract exists between two parties to mean anyone not bound by the … Read more
Difference between Mutable objects and Immutable objects [duplicate]
Mutable objects have fields that can be changed, immutable objects have no fields that can be changed after the object is created. A very simple immutable object is a object without any field. (For example a simple Comparator Implementation). class Mutable{ private int value; public Mutable(int value) { this.value = value; } //getter and setter … Read more
What is the cascading module used for? Why it’s called “cascade”?
“Cascading” in this context means that because more than one stylesheet declaration could apply to a particular piece of HTML, there has to be a known way of determining which specific stylesheet rule applies to which piece of HTML. The rule used is chosen by cascading down from the more general declarations to the specific … Read more
java howto ArrayList push, pop, shift, and unshift
ArrayList is unique in its naming standards. Here are the equivalencies: Array.push -> ArrayList.add(Object o); // Append the list Array.pop -> ArrayList.remove(int index); // Remove list[index] Array.shift -> ArrayList.remove(0); // Remove first element Array.unshift -> ArrayList.add(int index, Object o); // Prepend the list Note that unshift does not remove an element, but instead adds one … Read more
What’s a “canonical path”?
The whole point of making anything “canonical” is so that you can compare two things. For example, both ../../here/bar/x and ./test/../../bar/x may refer to the same location, but you can’t do a textual comparison on the two paths. However, if you turn them into their canonical representation, they both become ../bar/x, and we see that … Read more
What is the difference between an Abstract Syntax Tree and a Concrete Syntax Tree?
A concrete syntax tree represents the source text exactly in parsed form. In general, it conforms to the context-free grammar defining the source language. However, the concrete grammar and tree have a lot of things that are necessary to make source text unambiguously parseable, but do not contribute to actual meaning. For example, to implement … Read more
BCL (Base Class Library) vs FCL (Framework Class Library)
The Base Class Library (BCL) is literally that, the base. It contains basic, fundamental types like System.String and System.DateTime. The Framework Class Library (FCL) is the wider library that contains the totality: ASP.NET, WinForms, the XML stack, ADO.NET and more. You could say that the FCL includes the BCL.
What are greenfield and brownfield applications?
Greenfield in other disciplines like software engineering, a greenfield is also a project which lacks any constraints imposed by prior work. The analogy is to that of construction on greenfield land where there is no need to remodel or demolish an existing structure. (from http://en.wikipedia.org/wiki/Greenfield_project) Brownfield Brownfield development is a term commonly used in the … Read more
What does WISC (stack) mean? [closed]
Or WISA: Windows, IIS, SQL Server, ASP.net I don’t know why anyone would want to call it WISC, as these people are essentially saying “We will never ever use VB.NET, IronPython, IronRuby, F# or any other .NET Language”. Also calling it .NET (WISN) sounds a bit weird as well, since ASP.NET is the Web-Technology of … Read more
