+
+## Getting Started with Compojure
+
+Compojure is a DSL for *quickly* creating *performant* web applications
+in Clojure with minimal effort:
+
+```clojure
+(ns myapp.core
+ (:require [compojure.core :refer :all]
+ [org.httpkit.server :refer [run-server]])) ; httpkit is a server
+
+(defroutes myapp
+ (GET "/" [] "Hello World"))
+
+(defn -main []
+ (run-server myapp {:port 5000}))
+```
+
+Create a project with [Leiningen](http://leiningen.org/):
+
+```
+lein new myapp
+```
+
+Add your dependencies:
+
+```
+[compojure "1.1.8"]
+[http-kit "2.1.16"]
+```
+
+And run:
+
+```
+lein run -m myapp.core
+```
+
+View at: <http://localhost:5000/>
+
+Compojure apps will run on any ring-compatible server, but we recommend
+[http-kit](http://http-kit.org/) for its performance and
+[massive concurrency](http://http-kit.org/600k-concurrent-connection-http-kit.html).
+
+### Routes
+
+In compojure, each route is an HTTP method paired with a URL-matching pattern,
+an argument list, and a body.
+
+```clojure
+(defroutes myapp
+ (GET "/" [] "Show something")
+ (POST "/" [] "Create something")
+ (PUT "/" [] "Replace something")
+ (PATCH "/" [] "Modify Something")
+ (DELETE "/" [] "Annihilate something")
+ (OPTIONS "/" [] "Appease something")
+ (HEAD "/" [] "Preview something"))
+```
+
+Compojure route definitions are just functions which
+[accept request maps and return response maps](https://github.com/mmcgrana/ring/blob/master/SPEC):
+
+```clojure
+(myapp {:uri "/" :request-method :post})
+; => {:status 200
+; :headers {"Content-Type" "text/html; charset=utf-8}
+; :body "Create Something"}
+```
+
+The body may be a function, which must accept the request as a parameter:
+
+```clojure
+(defroutes myapp
+ (GET "/" [] (fn [req] "Do something with req")))
+```
+
+Route patterns may include named parameters,
+
+```clojure
+(defroutes myapp
+ (GET "/hello/:name" [name] (str "Hello " name)))
+```
+
+You can match entire paths with *
+
+```clojure
+(defroutes myapp
+ (GET "/file/*.*" [*] (str *)))
+```
+
+Handlers may utilize query parameters:
+
+```clojure
+(defroutes myapp
+ (GET "/posts" []
+ (fn [req]
+ (let [title (get (:params req) "title")
+ author (get (:params req) "title")]
+ " Do something with title and author"))))
+```
+
+Or, for POST and PUT requests, form parameters
+
+```clojure
+(defroutes myapp
+ (POST "/posts" []
+ (fn [req]
+ (let [title (get (:params req) "title")
+ author (get (:params req) "title")]
+ "Do something with title and author"))))
+```
+
+
+### Return values
+
+The return value of a route block determines at least the response body
+passed on to the HTTP client, or at least the next middleware in the
+ring stack. Most commonly, this is a string, as in the above examples.
+But, you may also return a [response body](https://github.com/mmcgrana/ring/blob/master/SPEC):
+
+```clojure
+(defroutes myapp
+ (GET "/" []
+ {:status 200 :body "Hello World"})
+ (GET "/is-403" []
+ {:status 403 :body ""})
+ (GET "/is-json" []
+ {:status 200 :headers {"Content-Type" "application/json"} :body "{}"}))
+```
+
+### Static Files
+
+To serve up static files, use `compojure.route.resources`.
+Resources will be served from your project's `resources/` folder.
+
+```clojure
+(require '[compojure.route :as route])
+
+(defroutes myapp
+ (GET "/")
+ (route/resources "/")) ; Serve static resources at the root path
+
+(myapp {:uri "/js/script.js" :request-method :get})
+; => Contents of resources/public/js/script.js
+```
+
+### Views / Templates
+
+To use templating with Compojure, you'll need a template library. Here are a few:
+
+#### [Stencil](https://github.com/davidsantiago/stencil)
+
+[Stencil](https://github.com/davidsantiago/stencil) is a [Mustache](http://mustache.github.com/) template library:
+
+```clojure
+(require '[stencil.core :refer [render-string]])
+
+(defroutes myapp
+ (GET "/hello/:name" [name]
+ (render-string "Hello {{name}}" {:name name})))
+```
+
+You can easily read in templates from your resources directory. Here's a helper function
+
+```clojure
+(require 'clojure.java.io)
+
+(defn read-template [filename]
+ (slurp (clojure.java.io/resource filename)))
+
+(defroutes myapp
+ (GET "/hello/:name" [name]
+ (render-string (read-template "templates/hello.html") {:name name})))
+```
+
+#### [Selmer](https://github.com/yogthos/Selmer)
+
+[Selmer](https://github.com/yogthos/Selmer) is a Django and Jinja2-inspired templating language:
+
+```clojure
+(require '[selmer.parser :refer [render-file]])
+
+(defroutes myapp
+ (GET "/hello/:name" [name]
+ (render-file "templates/hello.html" {:name name})))
+```
+
+#### [Hiccup](https://github.com/weavejester/hiccup)
+
+[Hiccup](https://github.com/weavejester/hiccup) is a library for representing HTML as Clojure code
+
+```clojure
+(require '[hiccup.core :as hiccup])
+
+(defroutes myapp
+ (GET "/hello/:name" [name]
+ (hiccup/html
+ [:html
+ [:body
+ [:h1 {:class "title"}
+ (str "Hello " name)]]])))
+```
+
+#### [Markdown](https://github.com/yogthos/markdown-clj)
+
+[Markdown-clj](https://github.com/yogthos/markdown-clj) is a Markdown implementation.
+
+```clojure
+(require '[markdown.core :refer [md-to-html-string]])
+
+(defroutes myapp
+ (GET "/hello/:name" [name]
+ (md-to-html-string "## Hello, world")))
+```

+CoffeeScript ist eine kleine Sprache, die eins zu eins nach JavaScript übersetzt wird - es findet keine Interpretation zur Laufzeit statt.
+Als Nachfolger von JavaScript konzipiert, gibt CoffeeScript sein Bestes, lesbaren, gut formatierten und sauber laufenden JavaScript-Code zu erzeugen, der in jeder JavaScript-Laufzeit einwandfrei funktioniert.
+
+Auf [der CoffeeScript Website](http://coffeescript.org/) gibt es ein ausführliches Tutorial.
+
+``` coffeescript
+# CoffeeScript ist eine dieser Sprachen für "Hipster"
+# und folgt daher vielen Trends und Einflüssen aus modernen Sprachen.
+# Kommentare werden daher wie in Ruby und Python mit Hashes gekennzeichnet
+
+###
+Kommentarblöcke sehen aus wie diese und werden direkt nach '/ *'s und '* /'s
+im erzeugten JavaScript umgewandelt.
+
+Vorweg: bevor du mit CoffeeScript anfängst, solltest du bereits einen guten
+Überblick über die Sprache JavaScript haben.

- Read the [Perl 6 Advent Calendar](http://perl6advent.wordpress.com/). This is probably the greatest source of Perl 6 information, snippets and such.
- Come along on `#perl6` at `irc.freenode.net`. The folks here are always helpful.
- Check the [source of Perl 6's functions and classes](https://github.com/rakudo/rakudo/tree/nom/src/core). Rakudo is mainly written in Perl 6 (with a lot of NQP, "Not Quite Perl", a Perl 6 subset easier to implement and optimize).
- Read the [Synopses](perlcabal.org/syn). They explain it from an implementor point-of-view, but it's still very interesting.

Swift is a programming language for iOS and OS X development created by Apple. Designed to coexist with Objective-C and to be more resilient against erroneous code, Swift was introduced in 2014 at Apple's developer conference WWDC. It is built with the LLVM compiler included in Xcode 6 beta.
+The official [Swift Programming Language](https://itunes.apple.com/us/book/swift-programming-language/id881256329) book from Apple is now available via iBooks.
+
See also Apple's [getting started guide](https://developer.apple.com/library/prerelease/ios/referencelibrary/GettingStarted/LandingPage/index.html), which has a complete tutorial on Swift.

+TypeScript is a language that aims at easing development of large scale applications written in JavaScript.
+TypeScript adds common concepts such as classes, modules, interfaces, generics and (optional) static typing to JavaScript.
+It is a superset of JavaScript: all JavaScript code is valid TypeScript code so it can be added seamlessly to any project. The TypeScript compiler emits JavaScript.
+
+This article will focus only on TypeScript extra syntax, as oposed to [JavaScript] (../javascript/).
+
+To test TypeScript's compiler, head to the [Playground] (http://www.typescriptlang.org/Playground) where you will be able to type code, have auto completion and directly see the emitted JavaScript.
+
+```ts
+//There are 3 basic types in TypeScript
+var isDone: boolean = false;
+var lines: number = 42;
+var name: string = "Anders";
+
+//..When it's impossible to know, there is the "Any" type
+var notSure: any = 4;
+notSure = "maybe a string instead";
+notSure = false; // okay, definitely a boolean
+
+//For collections, there are typed arrays and generic arrays
+var list: number[] = [1, 2, 3];
+//Alternatively, using the generic array type
+var list: Array<number> = [1, 2, 3];
+
+//For enumerations:
+enum Color {Red, Green, Blue};
+var c: Color = Color.Green;
+
+//Lastly, "void" is used in the special case of a function not returning anything
+function bigHorribleAlert(): void {
+ alert("I'm a little annoying box!");
+}
+
+//Functions are first class citizens, support the lambda "fat arrow" syntax and use type inference
+//All examples are equivalent, the same signature will be infered by the compiler, and same JavaScript will be emitted
+var f1 = function(i: number) : number { return i * i; }
+var f2 = function(i: number) { return i * i; } //Return type infered
+var f3 = (i : number) : number => { return i * i; }
+var f4 = (i: number) => { return i * i; } //Return type infered
+var f5 = (i: number) => i * i; //Return type infered, one-liner means no return keyword needed
+
+//Interfaces are structural, anything that has the properties is compliant with the interface
+interface Person {
+ name: string;
+ //Optional properties, marked with a "?"
+ age?: number;
+ //And of course functions
+ move(): void;
+}
+
+//..Object that implements the "Person" interface
+var p : Person = { name: "Bobby", move : () => {} }; //Can be treated as a Person since it has the name and age properties
+//..Objects that have the optional property:
+var validPerson : Person = { name: "Bobby", age: 42, move: () => {} };
+var invalidPerson : Person = { name: "Bobby", age: true }; //Is not a person because age is not a number
+
+//..Interfaces can also describe a function type
+interface SearchFunc {
+ (source: string, subString: string): boolean;
+}
+//..Only the parameters' types are important, names are not important.
+var mySearch: SearchFunc;
+mySearch = function(src: string, sub: string) {
+ return src.search(sub) != -1;
+}
+
+//Classes - members are public by default
+class Point {
+ //Properties
+ x: number;
+
+ //Constructor - the public/private keywords in this context will generate the boiler plate code
+ // for the property and the initialization in the constructor.
+ // In this example, "y" will be defined just like "x" is, but with less code
+ //Default values are also supported
+ constructor(x: number, public y: number = 0) {
+ this.x = x;
+ }
+
+ //Functions
+ dist() { return Math.sqrt(this.x * this.x + this.y * this.y); }
+
+ //Static members
+ static origin = new Point(0, 0);
+}
+
+var p1 = new Point(10 ,20);
+var p2 = new Point(25); //y will be 0
+
+//Inheritance
+class Point3D extends Point {
+ constructor(x: number, y: number, public z: number = 0) {
+ super(x, y); //Explicit call to the super class constructor is mandatory
+ }
+
+ //Overwrite
+ dist() {
+ var d = super.dist();
+ return Math.sqrt(d * d + this.z * this.z);
+ }
+}
+
+//Modules, "." can be used as separator for sub modules
+module Geometry {
+ export class Square {
+ constructor(public sideLength: number = 0) {
+ }
+ area() {
+ return Math.pow(this.sideLength, 2);
+ }
+ }
+}
+
+var s1 = new Geometry.Square(5);
+
+//..Local alias for referencing a module
+import G = Geometry;
+
+var s2 = new G.Square(10);
+
+//Generics
+//..Classes
+class Tuple<T1, T2> {
+ constructor(public item1: T1, public item2: T2) {
+ }
+}
+
+//..Interfaces
+interface Pair<T> {
+ item1: T;
+ item2: T;
+}
+
+//..And functions
+var pairToTuple = function<T>(p: Pair<T>) {
+ return new Tuple(p.item1, p.item2);
+};
+
+var tuple = pairToTuple({ item1:"hello", item2:"world"});
