Chat on the Air with LinPsk

The original international electronic hobbyist community is ham radio. Here are the basics of the chat room without the room.
Future Plans

When beginning work on LinPsk, my objective was to learn C++ and to develop a PSK31 program for Linux that was easy to use. KDevelop was a great help for me during this development. Meanwhile, I implemented RTTY as an additional mode. This mode works, but the decoder part should be improved. At that point, I tried to modify the code to get a framework for implementing different digital modes. I tried to implement MFSK16, but that mode is not functional as of yet. So this is another point for future developments.

I was asked to port LinPsk to Mac OS X. That was an interesting challenge and thus DarwinPsk was born. At the moment, my development platform is a dual-boot iBook with Mac OS X and Gentoo Linux. All examples were taken from the Gentoo Linux part and KDE 3.2. Now I maintain two distributions and receive many proposals for improving the program. Of course, I receive bug reports as well. The latest documentation was version 0.6, dated January 2002, so something new is needed. Help is welcome in the form of writing user-oriented documentation, testing the program or making proposals for improvements or reporting bugs. Even implementing new modes or writing is possible. Improving existing programs or designing new modes fits well with the experimental nature of amateur radio. And, believe me, the ideas of open source fit the spirit of ham radio.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
