Subversion, Games, NTP, and IPSec

by chromatic
Linux Newsletter for 01/06/2003

Welcome to the first Linux newsletter for 2003. I hope you had the chance to take a holiday at the end of the year to rest and recharge. (If you're lucky, you've already recovered from your holiday.) Since the newsletter was on hiatus, there's lots to cover this issue.

Rafael Garcia-Suarez wrote the second article in his Subversion saga, demonstrating Subversion for multi-developer projects. If you're not using source control, it's time to start. (If you are using source control--especially CVS--you ought to take a look at Subversion.)

Your editor attended an independent game developers conference several weeks ago and found a lot of similarities to open source development. Despite industry consolidation and ever-increasing game complexity, there just may be room for small, focused development teams to carve their own niches. Read more in Return of the Independent Game Developer?.

Dru Lavigne's still working through Cryptosystems. In her latest installment, she's moved from theory to practice, and demonstrates how to configure IPSec. This one's marked FreeBSD specific, but the concepts are very similar across all of the free Unixes.

The second-most valuable tool a system administrator can have is an accurate set of logs. (The most valuable tool is either a BOFH excuse-a-day calendar or lots of bandwidth.) Across servers, accuracy in logs requires accuracy in timekeeping. That led Glenn Graham to write a nice little piece on NTP. You can't make time, but you can keep it better.

Howard Wen didn't balk at receiving the assignment to "find some interesting open source games, write about them, and interview the developers." Yes, we've finally started to publish his series. This time, he takes a look at Falcon's Eye, an amazing graphical interface for the long-beloved Nethack. We'll shortly have an interview with the lead developer. Read more in Falcon's Eye: The Making Over of Nethack.

These are just selected highlights; there are other wonderful articles worth reading, as always, including book excerpts ("Radius," "MySQL Cookbook," and even a nice bit about the writing of "Apache: The Definitive Guide.") As always, there are several good weblogs as well, especially with the 25th Anniversary reminiscences underway. Find them all linked off of the O'Reilly Network home page.

Until next week,

ONLamp.com and Linux DevCenter Top Five Articles Last Week

  1. Cryptosystems: Configuring IPSec
    VPNs make it possible to have secure networks on top of the insecure public Internet. Having explained the concepts, Dru Lavigne's newest Cryptosystems article demonstrates how to configure IPSec.

  2. Buffer Overflows in SSH and PHP
    Noel Davis looks at buffer overflows in SSH, PHP, typespeed, Cyrus IMAP Server, Cyrus SASL library, and pdftops; and problems with PFinger, KDE, and zkfingerd.

  3. Return of the Independent Game Developer?
    How different are games from other potentially open source programs? The recent Independent Game Developers Conference lead chromatic to ask that very question. Find out what's happening in the game development world and why some people think independent developers are about to become very important.

  4. Falcon's Eye: The Making-Over of Nethack
    Few games have the staying power of Nethack, yet its interface hasn't strayed from its roguelike roots. Enter Jaakko Peltonen's Falcon's Eye. Gaming author Howard Wen explores the new clothes on a classic game.

  5. Synchronizing Networks with NTP
    Accurate timekeeping is vital to accurate records, and accurate logs are the mainstay of good system administration. Glenn Graham explains NTP (the Network Time Protocol) and how to put it to work on your network.
