Qt is the standard framework for high performance, cross-platform application development. Trolltech ASA is licensing its Qt cross-platform development framework under the GNU General Public License version 3 (GPL v3), with immediate effect. GNU founder Richard Stallman said:
I am very pleased that Trolltech has decided to make Qt avaliable under GPL v3. This will allow parts of KDE to adopt GPL v3 too. Even better, Trolltech has made provisions for a smooth migration to future GPL versions if it approves of them.
Qt is already available under the GPL v2 and will continue to be so in addition to the GPL v3.
The GPL v3 license will make it easy and safe for free software developers to use Trolltech's Qt with the most recent license framework from the Free Software Foundation. Trolltech hopes that its move will inspire free software projects to use GPL v3 when programming with Qt.

There is a program called Ping Tunnel to send TCP traffic over ICMP. From the project home page:
Ptunnel is an application that allows you to reliably tunnel TCP connections to a remote host using ICMP echo request and reply packets, commonly known as ping requests and replies. At first glance, this might seem like a rather useless thing to do, but it can actually come in handy in some cases. The following example illustrates the main motivation in creating ptunnel:
Setting: You're on the go, and stumble across an open wireless network. The network gives you an IP address, but won't let you send TCP or UDP packets out to the rest of the internet, for instance to check your mail. What to do? By chance, you discover that the network will allow you to ping any computer on the rest of the internet. With ptunnel, you can utilize this feature to check your mail, or do other things that require TCP.
Absolutely fantastic -- it Just Works. Download ping tunnel here.
Christina has published a nice list of 50 apps to get your office on open source software. This is a worth bookmark page:
Open source software has a lot to offer the business world. Aside from the fact that they’re generally free, many open source programs are more secure, reliable and customizable than their proprietary counterparts. In fact, many large companies, including big names like Amazon, Google, and Yahoo, run their servers with Linux rather than Windows. Open source software is often some of the best software for the job, even when cost is no consideration. So how can you make open source software work for your business? Here are 50 apps that can help your office get on track to join the growing numbers of businesses that have made the switch to open source.
The intention seems to be good, but there are few errors. For example Skype is not open source or GNOME is not Linux distribution. I hope author will fix out errors.

Looks like Linux adoption getting stronger and stronger each day :)
Adobe Flex is a software development kit and an IDE for a group of technologies initially released in March of 2004 by Macromedia to support the development and deployment of cross platform, rich Internet applications based on their proprietary Macromedia Flash platform.
Now Adobe has announced Flex Builder Linux Alpha. This is a native Linux port of the Flex Builder IDE based on Eclipse for building rich Internet applications:
Flex Builder Linux is a plugin-only version of the Flex Builder that you can use to build Flex applications on Linux. We wanted to get an early release out with the base Flex Builder features so you could begin to provide us with your feedback and let us know your priorities for additional features.

Intel has open-sourcing their cross-platform Thread Building Blocks 2.0 (TBB) template library. This is considered as Intel's largest open-source commitment to date. TBB is a popular software C++ template library that simplifies the development of software applications running in parallel on multicore computer. From the project page:
Intel Threading Building Blocks (TBB) offers a rich and complete approach to expressing parallelism in a C++ program. It is a library that helps you leverage multi-core processor performance without having to be a threading expert. Threading Building Blocks is not just a threads-replacement library. It represents a higher-level, task-based parallelism that abstracts platform details and threading mechanism for performance and scalability.
For developers, the clear benefits of Threading Building Blocks are:
1. TBB significantly reduces the number of lines of code required to develop multithreaded applications;
2. TBB significantly reduces the programming complexity for developing multithreaded applications (by abstracting many details of thread management);
3. TBB's task manager automatically analyzes the system the software is running on, chooses the optimal number of threads, and performs load balancing that spreads out the work evenly across all processor cores;
4. As a result, TBB threaded applications automatically scale to fully utilize all available processing cores on whatever computer they run on – including future systems that will have many more cores than are available (or affordable) today.
