A Tale of DXPC: Differential X Protocol Compression

When you have a slow modem and want faster transfer rates, data compression with this program is the answer.
Conclusion

The compression methods used by DXPC are compressions that cannot be done by hardware compression in the modem. In fact, I believe it complements other compression techniques to increase overall performance. The authors have done an excellent job of developing and maintaining a stable, easily compiled and easy to use program. I wish I had found it a year ago. Please note that if you use X authority with a .Xauthority file, some extra steps are necessary to use DXPC. These steps are covered in the README file distributed with the source.

Brian Pane informs me that they are preparing to release DXPC 3.6.0 soon. He has added compression for more X messages.

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.
