Qt To Be Licensed Under GPL version 3

Posted on in Categories GNU/Open source, Kde, Linux, News last updated January 19, 2008

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.

Open source software has a lot to offer the business world.
