Dynamic Graphics and Personalization

A continuation of the discussion on creating graphics dynamically on the Web.
Conclusion

Last month, we saw how to create simple dynamic stock graphs using the GIFgraph package. This month, we saw how such dynamically created graphics can fit into a larger application, allowing users to see information about their stock portfolios. The combination of a relational database, mod_perl and GIFgraph makes it possible to create such a simple application in under 400 lines of code. You can undoubtedly think of many other applications in which dynamically created graphics would be useful—let your imagination go wild!

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
