Ethan McCallum demonstrates how easy it is to use. [LinuxDevCenter.com] Tales of Rescuing Old Hardware If you're careful, you can often pick up viable hardware from companies throwing out machines too old to run the latest and greatest Windows software.

Bosworth's Web of Data Google's Adam Bosworth's keynote at the 2005 MySQL Users Conference was a call to audience members to "do for information what HTTP did for user interface." The web was successful because it offered a simple, sloppy, standards-based, scalable platform, and the challenge is to take a database and do the same. Daniel Steinberg covered Bosworth's talk, and provides this report. [ONLamp.com] Trust and Zeal in Open Source Advocacy Advocacy is critical to the spread of open source and free software.

[LinuxDevCenter.com] Security Alerts Adventures in Migrating to New Linux Distributions Linux doesn't stand still, whether it's the kernel or GNU/Linux distributions.

Kevin Farnham recently switched distributions several times; here are some hard-earned lessons from the process. [LinuxDevCenter.com] The Bacula Philosophy Bacula is a mature client-server backup solution that runs on several platforms and flexibly meets many needs.

[ONLamp.com] Securing Web Forms with PEAR's Text_CAPTCHA On the internet, how can you tell a person from a program written to act just like a person? One approach is to ask a question that (usually) only a human could answer. Marcus Whitney shows off a PEAR package to do this easily from PHP. [ONLamp.com] Extreme System Administration Learning from programmers seems like a horrible idea, but good developer teams work together productively to solve problems effectively and more efficiently than they could on their own.

[O'Reilly Network] Security Alerts Perspectives on the Shared Source Initiative Microsoft's Shared Source Initiative seems like an odd mix for the company when it works openly and a clever shot across the bow of open source when it works selfishly. How can the rest of us reconcile both positions? Microsoft ex-employee Stephen Walli shares his perspectives on the Shared Source Initiative from within and without the company. [ONLamp.com] Calculating Entropy for Data Miners Quick--what's the relationship between the columns of your database? Don't know?

As Subversion continues to take over from CVS, more advanced interfaces have started to appear. How do they compare to each other? How do they compare to the Secure Batch Email with UUCP and SSH Not everyone has reliable, always-on Internet access. For some, reliability has to come through software, not hardware. Fortunately, protocols designed to work around slow and unreliable networks still work. Christophe Prevotaux demonstrates how to set up FreeBSD, Postfix, and SSH to send and receive email via UUCP. [ONLamp.com] Rolling with Ruby on Rails, Part 2 Curt Hibbs introduced Ruby on Rails by building a simple but functional web application in just a few minutes. Does the ease of use continue?
