Greetings, subscribers to the weekly Linux newsletter. If you've already
read the title of this mailing (scroll back a few paragraphs) or the
subject line, you know you're in for a summary of the news of the week
about free and open source software as seen on the O'Reilly Network.

Hop on.

The wild wide world of the Internet features plenty of audiences and,
unfortunately, plenty of opportunities for automated, drive-by malice.
Once a malicious user finds a potential vulnerability, he may return for
personal destruction. One way to defend your sites is to detect this
behavior with a honeypot. Though there are some legal and ethical
questions about presenting targets too tempting to resist, running a
honeypot well can give you plenty of information to protect your networks.
Peter Mikhalenko explains how:

Growth is a nice thing, if you serve customers. It can also be painful; as
your site gets more popular, you often need more bandwidth, more disk
space, and more CPU to handle the extra load--but not always. Tuning your
site configuration can reduce your resource requirements dramatically.
Yogesh Makwana demonstrates how a little proxying and a little porting to
persistent environments helped his group turn an overloaded Apache httpd
server back into a quick and lightweight system that's ready to take on
many more users:

One problem with a general purpose language is that sometimes there are
plenty of good ways to accomplish a specific task. That's good from an
evolutionary competition sense, if things always get better. It can be
difficult to reuse code, however, and woe to beginners who just want to
know how to start with something. The Python community has started to
address this issue in web programming by defining a set of standards for
web development. James Gardner explains this standard--WSGI:

In weblogs this week, Curtis Poe suggests stricter liabilities for
software manufacturers:

... then gave guidelines for making small systems that can grow into
larger ones:

Anton Chuvakin argued that you should allow no access without audit:

Carla Schroder linked to her three-part series about IPv6 in the real world:

http://www.oreillynet.com/linux/blog/2006/09/ipv6_for_real_1.html

Mike Loukides wondered which features of Google's development process
might apply to the real world:

http://www.oreillynet.com/onjava/blog/2006/10/agile_or_not_at_google_1.html

Ann Barcomb summarized a lively week in the development of Perl 6:

http://www.oreillynet.com/onlamp/blog/2006/10/perl_6_mailing_list_summary_24.html

Sam Smith decried Intel's claims of openness as fraudulent:

http://www.oreillynet.com/onlamp/blog/2006/09/intels_open_source_fraud.html

Jeremy Jones found the latest programming popularity index amusing:

http://www.oreillynet.com/onlamp/blog/2006/09/python_supplants_c_on_tiobe_in.html

Chris Tyler suggested putting all users on a Unix system in their own
private user groups:

http://www.oreillynet.com/onlamp/blog/2006/09/using_user_private_groups.html

Your editor reviewed the very useful Test::Perl::Critic module:

http://www.oreillynet.com/onlamp/blog/2006/09/cpan_module_review_testperlcri.html

... then illustrated necessary and overlooked principles of agile software
development with furry Star Trek fan fiction:

http://www.oreillynet.com/onlamp/blog/2006/09/this_chocolate_cake_recipe_tas.html

Yes, you read that last description correctly. Yes, it's safe for work.

No, he'll never do that again,
