HTTP Proxies, PHP Web Services, Open Source Telephony, and Stas Bekman

Linux Newsletter for 07/07/2003

Greetings from OSCON 2003. Today's the opening day and our coverage is just starting. Be sure to check the official OSCON page and the unofficial OSCON wiki for the latest news and information.

If you're not the conferency type, never fear. Our usual coverage of open source tools and development continues. Here's what's new this week.

Dru Lavigne continues her series on proxies with HTTP Proxies. In this installment, she explains just enough HTTP to introduce how two popular HTTP proxies, bfilter and Middleman, work. She also demonstrates their setup and configuration.

There's been a lot of noise recently about web services. While converting from Farenheit to Celsius is interesting the first time, it's hardly the earth-shaking revelation you'd expect. Fortunately, companies such as Amazon and Google are quietly using web services to give access to their data, which you can access through well-documented APIs. PHP Cookbook author Adam Trachtenberg demonstrates A PHP Web Services Client that lets you search and display books from Amazon.

Open source software has reached a dominant position in several markets. It has yet to penetrate telephony applications. Perhaps Asterisk will help; it is open source call-processing software that's also extensible for creating more sophisticated applications. Better yet, it runs on commodity Linux and OpenBSD boxes. John Todd explains more in Asterisk: A Bare-Bones VoIP Example.

Finally, mod_perl hacker, documenter, and full-time employee Stas Bekman recently agreed to answer several questions about his new book, Practical mod_perl, written with Eric Cholet. Find out what's new in Apache 2 and mod_perl 2 and what it's like to be sponsored full-time on an open source project in Stas Bekman on mod_perl 2.

That's all for this week, until we reveal the secrets brewing for Tuesday night's State of the Onion talks. (The Perl announcement is a biggie. Stay tuned.)

And now I'm off to find a network connection,

O'Reilly Network and Linux DevCenter Top Five Articles Last Week

  1. Video Playback and Encoding with MPlayer and MEncode
    No consumer Linux box is complete without the ability to play digital video files. Until recently, this was difficult -- the codecs weren't freely available or distributable. MPlayer seeks to change this. KIVILCIM Hindistan introduces MPlayer and demonstrates some of its features.

  2. MySQL FULLTEXT Searching
    Storing text in your database is handy, but searching can be a pain. MySQL's FULLTEXT search can save your sanity. Joe Stump demonstrates how it works and gives several ideas on how to use it in your own applications.

  3. An Interview with the Author of Practical mod_perl
    Stas Bekman has maintained the mod_perl guide for ages. He's even been sponsored to work on improving mod_perl full time! The author of the recently released Practical mod_perl graciously agreed to this interview.

  4. Defending Your Site Against Spam
    To users, unsolicited commercial e-mail is an annoyance. To mail server administrators, it's a threat. Dru Nelson recently had his network attacked by spammers. He explains the various defenses he considered for protecting against future attacks.

  5. HTTP Proxies
    Now that you know all about proxies, you're ready to install and use an HTTP proxy. Dru Lavigne explores Squid and Middleman, two effective and powerful HTTP proxies.
