News and EditorialsThe Fenris Tracer, Analyzer, and GCC Decompiler
Michal Zalewski has released what appears to be an interesting new project, Fenris. Fenris is a combined tracer, stateful program analyzer, and partial GCC decompiler. The program is intended to discover information that conventional analysis and debugging tools miss. Fenris can be used to analyze executables, project source code is optional.
"This is not an interactive debugger, and it is not intended to find problems, bugs or security vulnerabilities automatically. But it is supposed to be a reliable, useful tool that works in real world and can deliver valuable information which can be used to detect known problems, but also to spot unique or not so obvious dynamic conditions."
The Fenris README file describes the operation of the tool in detail.
"Fenris is not supposed to find vulnerabilities or bugs, or to guess algorithms or describe protocols. It is supposed to report and analyze the execution path - detect and describe functional blocks, monitor data flow in the program, marking its lifetime, source, migration and destination, analyze how functions work and what conditions are evaluated."
The README file also makes note of the current state of the project:
"While functional, it is probably not tested sufficiently, there are many issues to fix, several known bugs, some portability issues. It is primarily being released to get user feedback, comments, and, most important, to request development support, as my resources are very limited, both in terms of available time and development platforms. This project is and will be distributed as a free software, regardless of projected use, accompanied by complete sources."
Fenris produces its output in a browsable form, analysis of the executed code is provided in a number of different tables.

"It comprises a Form generator, a Table and Query generator and a Report Designer. The introduction of the Report Designer is the central highlight of version 0.5. With just a few mouse-clicks it is possible to design reports, optionally including grouped data and subreports, and then print those reports." Knoda currently only supports MySQL, a Postgres driver is planned.

Introducing Cocoon 2.0 (O'Reilly). O'Reilly's XML.com site features an article on the Cocoon 2.0 documentation system by developer Stefano Mazzocchi. "Cocoon was designed as an abstract engine that could be connected to almost anything, but it ships with servlet and command line connectors. The servlet connector allows you to call Cocoon from your favorite servlet engine or application server. You can install it beside your existing servlets or JSPs. The command line interface allows you to generate static content as a batch process. It can be useful to pre-generate those parts of your site that are static, some of which may be easier to create by using Cocoon functionalities than directly"

Gnome and Slackware. For those of you who want to run Gnome under the Slackware distribution, a gnome-slackware mailing list has been announced. "The goal of the list is to provide an help for using gnome in slackware. It will also be the coordination place of the gnome packaging effort."
Understanding the KParts component architecture (IBM developerWorks). David Faure writes about KParts on IBM's developerWorks. "This article discusses KParts, an architecture for graphical components, found in KDE, the K Desktop Environment. KParts allows applications requiring the same functionality to share a component by embedding the graphical component into the application's window. This article compares KParts with other component models, such as CORBA, and describes the main concepts used in KParts, including actions, plug-ins, part managers, and GUI merging."
New Flightgear flight simulator. A new version of the Flightgear open-source flight simulator project has been released. The changes include some bug fixes and documentation work. (Thanks to Alex Perry.)

Colored MultiTabs widget for FLTK. Alexey Parshin has released version 0.8 of his Multi Row Tabs widget package for FLTK.
Wine license change clarification. Jeremy White has clarified his position on the recent Wine license change to the LGPL. "So, with each and every one of my major customers over the past three years, I have had a major, knock down, drag out fight over licensing. I have always insisted that changes we make to Wine be returned to Wine. This has meant (while in a sales situation) explaining the complexities of BSD versus GPL licenses."
Alexandre Julliard has posted the results of a vote taken in the Wine community, the majority of respondents support the switch to a Copyleft license.
First Broadcast 2000, now Cinelerra. Cinelarra is (or was) a product used in producing motion pictures on Linux PCs. Now the Cinelerra website simply says, "It's not here anymore. Why don't you go to this award winning page.", with a link to Microsoft.com (of all places). Cinelarra was a product of Heroine Virtual who may have simply wrapped Cinelarra code into other products.. "As the size and complexity of our software has grown, it is no longer possible to release it under individual's names because of these privacy issues. Credit is given as dictated by the GPL but our original code is released under the name Heroine Virtual Ltd." (Thanks to Wes Felter)
We're still hoping that someone will carve the excellent audio recorder/editor software out of Broadcast 2000 and make a new project. The Broadcast 2000 source code is still available here.

XML in Java: Java document model usage (IBM developerWorks). Dennis M. Sosnoski discusses techniques for the creation of XML from Java. "In this article, XML tool watcher Dennis Sosnoski compares the usability of several Java document models. It's not always clear what the tradeoffs are when you choose a model, and it can require extensive recoding to switch if you later change your mind. Combining sample code with analysis of the model APIs, the author gives recommendations for which models may really make your job easier. Includes code samples that show the methods for the five different document models."
Expiring Data with Hashbelts (O'Reilly). William Grosso writes about the use of Hashbelts in Java. "In this article I will show you how to use the hashbelt algorithm by using two distinct examples: implementing session keys and reimplementing the RemoteStubCache class from my previous articles on command objects in RMI. By the end of this article, you should feel comfortable using hashbelts in your code and understand when it is appropriate to do so."
Two Lisp updates. Paolo Amoroso has sent us two new items from the world of Lisp, CL-PDF version 0.45 is an update to the Common Lisp PDF generation library, and CLAWK is a common Lisp superset of AWK functionality.

Stackless Reincarnate (O'Reilly). Stephen Figgins delves into the issues behind stackless Python. "Stackless was a controversial modification to Python, separating its execution stack from the C execution stack, the C-stack. With Stackless you could set up multiple execution chains, switch between them, change them, or restart them. Uncoupled from the C-stack, you could capture the control flow of your Python program and manipulate it any way you wanted to."
