Emscripten: an LLVM to Javascript Compiler
Emscripten: An LLVM to JavaScript Compiler Alon Zakai Mozilla What? Why? Compiling to JavaScript ● The web is everywhere – PCs to iPads – No plugins, no installation required – Built on standards ● The web runs JavaScript Existing Compilers to JavaScript ● Google Web Toolkit: Java (Gmail, etc.) ● CoffeeScript ● Pyjamas: Python ● SCM2JS: Scheme ● JSIL: .NET bytecode ● (and many more) ● But C and C++ are missing! Emscripten ● Enables compiling C and C++ into JavaScript ● Written in JavaScript ● Open source http://emscripten.org https://github.com/kripken/emscripten Demos! ● Bullet ● SQLite ● Python, Ruby, Lua ● Real-world code – Large, complex codebases ● Manual ports exist – Typically partial and not up to date The Big Picture C or C++ LLVM Bitcode JavaScript Low Level Virtual Machine (LLVM) ● A compiler project (cf. GCC) ● Intermediate Representation: LLVM bitcode – Very well documented – Great tools ● Much easier to compile LLVM bitcode than compile C or C++ directly! How?

DLCGI Advanced Uses
DLCGI Advanced Uses Using DLCGI to achieve single sign-on with The Diver Solution In situations where authentication to DiveLine needs to be integrated with an existing authentication scheme, we provide "DLCGI", the DiveLine-Common Gateway Interface interfacing module. The "Common Gateway Interface" is a standard for interfacing external scripts and programs with a web server. How DLCGI works When dlcgi.exe is executed by the webserver, in the context of a user that the web server has already authenticated, it obtains a limited-lifetime one-time password from DiveLine. This password can be passed, via web page redirects, custom web page scripting, etc., to DivePort, NetDiver, or even ProDiver to allow the user to login. The typical strategy for using DLCGI is: 1. Configure DiveLine to accept DLCGI requests from your webserver. 2. Install dlcgi.exe in a scripts directory (e.g. /cgi-bin/) on your CGI-compliant webserver (e.g. IIS, Apache). You configure the name of your DiveLine server and other parameters using dlcgi.cfg in the same directory as the executable. 3. Restrict access to this script so that the webserver will only execute it when the user has already authenticated (e.g. Domain account). Typical uses • DivePort: Users go to the DivePort site, and are redirected to another URL for authentication. That URL, which runs dlcgi.exe, redirects the user back to the DivePort URL with a one-use authentication token. • ProDiver: When ProDiver connects to DiveLine, if configured with a DLCGI URL, it will access the URL in "raw" mode (see below) to obtain a parse-able result file containing a one-use DiveLine authentication token. -

What Is Dart?
1 Dart in Action By Chris Buckett As a language on its own, Dart might be just another language, but when you take into account the whole Dart ecosystem, Dart represents an exciting prospect in the world of web development. In this green paper based on Dart in Action, author Chris Buckett explains how Dart, with its ability to either run natively or be converted to JavaScript and coupled with HTML5 is an ideal solution for building web applications that do not need external plugins to provide all the features. You may also be interested in… What is Dart? The quick answer to the question of what Dart is that it is an open-source structured programming language for creating complex browser based web applications. You can run applications created in Dart by either using a browser that directly supports Dart code, or by converting your Dart code to JavaScript (which happens seamlessly). It is class based, optionally typed, and single threaded (but supports multiple threads through a mechanism called isolates) and has a familiar syntax. In addition to running in browsers, you can also run Dart code on the server, hosted in the Dart virtual machine. The language itself is very similar to Java, C#, and JavaScript. One of the primary goals of the Dart developers is that the language seems familiar. This is a tiny dart script: main() { #A var d = “Dart”; #B String w = “World”; #C print(“Hello ${d} ${w}”); #D } #A Single entry point function main() executes when the script is fully loaded #B Optional typing (no type specified) #C Static typing (String type specified) #D Outputs “Hello Dart World” to the browser console or stdout This script can be embedded within <script type=“application/dart”> tags and run in the Dartium experimental browser, converted to JavaScript using the Frog tool and run in all modern browsers, or saved to a .dart file and run directly on the server using the dart virtual machine executable. -
