Open Source Mobile Content Delivery Platform II »

Previously I have written on Volantis and MyMobileWeb as a mobile content delivery platform.

If you are looking a PHP based CMS for mobile, then you can plug-ins then you can add to the existing CMS to make the content mobile compatible.

Wap-2-Go is a add-on module to PHPNuke.  It is a Mobile Content Management System (CMS) Portal and a simple ‘all in the box’ solution for webmasters wishing to provide dynamic content to mobile users. Fully customisable to your own design, or simply use pre-designed themes to style your mobile portal.

Wap-2-Go is a mobile website that can be accessible on mobile phones, PDAs and other mobile devices, generated ‘on-the-fly’ from your site content. Customisable User Preferences allow a bespoke fit to any device and allow disabling of images by users to reduce their bandwidth/traffic (useful if charged per Kb by their provider). The use of Themes also allow easy styling of your mobile portal.

Wap-2-Go is fully WML (WAP1.1) and xHTML (WAP2.0) compliant. WML is the standard mark-up language for mobile devices; whilst xHTML (WAP 2.0) allows more advanced styling – giving your site an even more impressive look.

Open Source Mobile Content Delivery Platform »

I have written about Volantis, which is a open source mobility server for mobile content delivery.

Other than Volantis, MyMobileWeb is another good open source mobile content delivery platform

MyMobileWeb is a low-cost, modular, open-standards-based, open source software platform that simplifies the development of top-quality mobile web applications and portals, providing an advanced content & application adaptation environment.

It includes different modules which cover all the basic requirements that a complete and integrated mobile web site must fulfill, hiding from applications all complexity related to dealing with multiple delivery contexts. MyMobileWeb uses Device Information Simple API to recognize and obtain the capabilities of devices. As a value-added feature, MyMobileWeb incorporates some experimental modules capable of exploiting semantics in a mobile environment, implementing the concept of ‘Semantic Mobile Web’.

.NET Distribute and Parallel Program Execution Engine »

Dryad is an infrastructure which allows a programmer to use the resources of a computer cluster or a data center for running data-parallel programs. A Dryad programmer can use thousands of machines, each of them with multiple processors or cores, without knowing anything about concurrent programming.


A Dryad programmer writes several sequential programs and connects them using one-way channels. The computation is structured as a directed graph: programs are graph vertices, while the channels are graph edges. A Dryad job is a graph generator which can synthesize any directed acyclic graph. These graphs can even change during execution, in response to important events in the computation.

Dryad is quite expressive. It completely subsumes other computation frameworks, such as Google’s map-reduce, or the relational algebra. Moreover, Dryad handles job creation and management, resource management, job monitoring and visualization, fault tolerance, re-execution, scheduling, and accounting.

Java: Open Source Image Process Library »

ImageJ is a public domain Java image processing program inspired by NIH Image for the Macintosh. It runs, either as an online applet or as a downloadable application, on any computer with a Java 1.4 or later virtual machine. Downloadable distributions are available for Windows, Mac OS, Mac OS X and Linux.

It can display, edit, analyze, process, save and print 8-bit, 16-bit and 32-bit images. It can read many image formats including TIFF, GIF, JPEG, BMP, DICOM, FITS and "raw". It supports "stacks", a series of images that share a single window. It is multithreaded, so time-consuming operations such as image file reading can be performed in parallel with other operations.

It can calculate area and pixel value statistics of user-defined selections. It can measure distances and angles. It can create density histograms and line profile plots. It supports standard image processing functions such as contrast manipulation, sharpening, smoothing, edge detection and median filtering.

It does geometric transformations such as scaling, rotation and flips. Image can be zoomed up to 32:1 and down to 1:32. All analysis and processing functions are available at any magnification factor. The program supports any number of windows (images) simultaneously, limited only by available memory.

Spatial calibration is available to provide real world dimensional measurements in units such as millimeters. Density or gray scale calibration is also available.

ImageJ was designed with an open architecture that provides extensibility via Java plugins. Custom acquisition, analysis and processing plugins can be developed using ImageJ’s built in editor and Java compiler. User-written plugins make it possible to solve almost any image processing or analysis problem.

Open Source SMS Application Testing Tool for SMPP »

SMPPSim simulates an SMSC (Short Message Service Centre) which has an SMPP interface which can be used by software applications for sending and receiving SMS text messages. It is free of charge, open source and used by thousands of users all over the world.

SMPPSim is a testing utility which mimics the behaviour of an SMPP based SMSC. SMPP stands for Short Message Peer to Peer Protocol. SMSCs (Short Message Service Centres) from Logica Aldiscon support this protocol, as a means of allowing external (to the GSM network) applications to submit and receive SMS messages to / from the SMSC. Some other SMSC vendors also support SMPP.

If you are intending to implement support for SMS text messaging using the SMPP protocol in your application, you will need some way of testing your application. Ultimately of course, you should aim to use a real SMSC for testing before going live. Hopefully the network operator you are working with can supply a test SMSC for this purpose. In some cases however, two factors make SMPPSim a useful tool for the initial stages of testing:

  1. It can take months to acquire a connection to a GSM network
  2. Some network operators run stringent acceptance tests before they will allow your application to interact with the production SMSCs. It can take weeks to complete these tests, even if things go well.

So, it pays to have some independent means of doing your initial testing. Firstly so that your project is not completely dependent on acquiring a network connection in order to be able to progress, and secondly so that your code is as good as you can get it before entering the formal acceptance testing phase with the network operator.

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself.

When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a web site.

JSmooth provides a variety of wrappers for your java application, each of them having their own behaviour.


GCJ is a portable, optimizing, ahead-of-time compiler for the Java Programming Language. It can compile Java source code to Java bytecode (class files) or directly to native machine code, and Java bytecode to native machine code.

Compiled applications are linked with the GCJ runtime, libgcj, which provides the core class libraries, a garbage collector, and a bytecode interpreter. libgcj can dynamically load and interpret class files, resulting in mixed compiled/interpreted applications. It has been merged with GNU Classpath and supports most of the 1.4 libraries plus some 1.5 additions.

GCJ can also be configured as a cross-compiler, suitable for embedded systems programming.
