Hawaii DVTS and VLC Technical Information

At the University of Tennessee, we are providing two high-quality, permanent multimedia streams. The first is an audio feed of our radio station WUOT, while the second is a stream of our student television station TVC. Both are multicast streams.

WUOT is being streamed using VLC, and is an MPEG-1 stream running at 448k for superior sound. While any player capable of tuning into a multicast MPEG stream should be able to receive it, we recommend using the free, open-source VLC player available for most popular platforms. Getting the stream is simple. After running VLC, select 'File' and choose 'Open Network Stream' (or similar). Then, pick UDP/RDP Multicast, inserting 233.13.122.247 as the IP, and 1234 as the port. That's it!

We are using DVTS to stream TVC out as raw DV at a constant rate of about 30 megabits. In order to receive the stream, you must use the DVTS client, which for some platforms is integrated within a GUI and for others is a standalone application. Although offered on many platforms, the most stable, robust, and user-friendly version is for Windows (an even more recent version for Windows XP only can be found here and is the suggested version to use on that platform), but Mac and Linux versions are also available. Instructions for opening the stream unfortunately vary from version to version, but essentially you will find a 'Join Multicast' or similar option. The IP to use is 233.13.122.247, and the port is 8000.

Renowned Linux/Open Source Evangelist Complains About Poor UI

In this tremendous post, John Gruber comments on an article Eric S. Raymond wrote regarding his trouble connecting to a network printer through Linux. The writing is entertaining, but the underlying implications for Open Source UI development, as well as for the feasibility of Linux as a mainstream consumer operating system, are very serious. Bottom line - there's a long way to go:

"It’s common for the Linux hacker set to poke fun at Windows’s wizard-style configuration tools, but the entire desktop Linux user interface is a pale imitation of Windows — much, much more of a rip-off of Windows than Windows ever was of the Mac. But the resemblance is merely cosmetic; functionally, desktop Linux is nowhere near as usable as Windows."

Internet Access a Human Right?

Apparently, the Estonian government thinks it is:

"In 2000, the parliament, perhaps inspired by their new gizmos, passed a law declaring Internet access a fundamental human right of its citizenry. A massive program is under way to expand access to the countryside, where economic development is hampered by lack of decent roads and other transportation links. The Internet, the government argues, is essential for life in the 21st century."
In many ways, I almost agree with them. More and more governments are offering e-services, and I fear that those without connectivity may soon receive unequal access to those services. The time may be approaching when agencies require an email address instead of a phone number.

You Call That a Standard?

Robert Glushko, an adjunct professor at the University of California at Berkeley, reflects how powerful interests can derail the work of well-established standards organizations. He also contends that the standards development in governmental organizations, such as the United Nations, is a very politicized process. High-minded goals, such as cheap global e-business standards, can easily be tarnished by money, power and access to powerful bureaucrats.
