Unlimited Web Conferencing for One Flat Rate
GoToMeeting(TM) is the easiest and most affordable way to conduct online
meetings with coworkers and clients--without ever leaving your desk. Best
of all, you can meet as much as you want for as long as you want--for one
low flat rate.

Dear Reader,
O'Reilly loves publishing books and articles. But we've noticed that
certain subjects need to reach you faster than book production can
accommodate, yet requires more depth than online articles provide. We've
settled on an agile solution with our PDF publishing program.
I mention this because we've recently released four new PDFs -- Web
Services on Rails, Building Tag Clouds in Perl and PHP, Atlas UpdatePanel
Control, and Search Engine Optimization -- and they're great. Each title
runs between 40 and 56 pages, is downloadable right now, and each costs
just $9.99. They're formatted as standard PDF documents without any of
that annoying DRM stuff, so you can enjoy them in your favorite PDF reader.
We have lots more interesting stuff in the pipeline too. You can see the
latest and greatest by visiting:
<http://pdfs.oreilly.com>
Hope you find something you like.
Until next time,
-Derrick

Josh Peterson from the Robot Co-Op
Brady Forrest interviews Josh Peterson, CEO of The Robot Co-op, in this
Where 2.0 preview podcast. Josh talks about his "network of networking
sites," which includes 43 Things, 43 Places, and 43 People. At Where 2.0,
Josh will be presenting 43 Places, where a user can list up to 43 places
they'd like to go during their life. The site allows people to share
stories about places they've been and read stories about places they'd
like to visit. (13 minutes, 38 seconds)

Building a Self-Healing Network
Wouldn't it be nice if your network services could detect their own
failures and gracefully restart? Sure, you could have cron or FAM jobs
always checking them, but that's so unrefined. Instead, consider Greg
Retkowski's solution: building a small Cfengine and NAGIOS combination to
detect and recover from failure.

Telling Stories at JavaOne
JavaOne 2006 left attendees with an incomplete answer to the big question:
will Sun open source Java? The answer was better than a definite maybe,
but not by much. Daniel Steinberg looks back at the conference, its mixed
message, and its many successes outside of the general sessions.

Standardizing Java Persistence with the EJB3 Java Persistence API
Dissatisfaction with entity beans as an "official" means of persisting
Java objects to databases has prompted a number of "unofficial"
approaches, such as the very popular Hibernate. Now EJB3 seems to have
learned its lesson: its new Java Persistence API allows you to persist
plain old Java objects (POJOs) with a minimum of fuss and just a few
annotations. Debu Panda looks at how to put this new standard to work.

Greetings...
The cynic in me thinks we could recycle old JavaOne stories, at least for
the coverage of whether or not Sun is going to release its Java
implementation under a F/OSS license. In last year's JavaOne roundup, I
wrote, "While this [overture to the open source community] wasn't followed
by a jaw-dropping announcement of open sourcing Java, Schwartz did cite
Sun's commitment to an open process [...] and declared the opening of the
source of its enterprise server [...] with a promise of 'more to come.'"
In 2004, Daniel Steinberg summarized a JavaOne roundtable hosted by Tim
O'Reilly on the "Big Question" of open sourcing Java, by saying "the
panelists helped lay out many of the challenges that must be addressed:
deciding what to open source, how to do so, and how to indicate
incompatible implementations." So maybe nobody should be surprised that
this year's "big news" was another baby step towards open sourcing Java,
with no idea of what year it will be when Sun actually does it.
Instead of writing general show impressions, this year Daniel Steinberg
focuses on this question of open sourcing Java, and Sun's two JavaOne
announcements on the topic: a new license intended to make it easier
to distribute the non-free JDK with certain Linux distributions, and
a promise that the open sourcing of Java is, according to Executive VP
of Software Rich Green, "not a question of whether, but a question of
how." In "Telling Stories at JavaOne," Daniel takes a thorough look at
the content and context of Sun's JavaOne announcements, and surveys
how they have been received by their intended audience in the open
source community.

You may be familiar with UML diagrams that show the relationships between
your classes and their members, but it can be much more than that. By
using UML to model deployment, you can understand and represent not just
your code, but the environment it runs in, and share this with sysadmins
and others. In the dev2dev article "Modeling Enterprise Java Applications
and Deployments," Jeff Davies says "the purpose of this article is to
demonstrate several effective ways to model modern software systems to
accurately and concisely communicate architectural, design, and deployment
details to the responsible parties in your enterprise."
<http://dev2dev.bea.com/pub/a/2006/05/modeling-enterprise.html>
In this week's feature article from java.net, Jacobus Steenkamp introduces
techniques for "Bringing Swing to the Web," saying "there is no reason why
web and Swing development should be mutually exclusive. In this article,
we will look at putting one of Swing's most overlooked (and basic)
features to work inside a web application."

own PC. Wei-Meng Lee shows you how to run the Mac operating system on an
emulator called PearPC.

4. Enhancing ASP.NET Pages with JavaScript
A sprinkling of JavaScript code can enhance the reach and responsiveness
of your ASP.NET web pages without sacrificing ASP.NET's secure,
server-based model for your coding. Matthew MacDonald, coauthor of ASP.NET
in a Nutshell, 2nd Edition, shows you how to use JavaScript in an ASP.NET
web page to perform three common tasks: showing a pop-up window, changing
control focus, and handling frame navigation. You can use these tricks to
quickly solve problems that have no native .NET solution.
<http://www.ondotnet.com/pub/a/dotnet/2003/09/15/aspnet.html>
***
5. ASP.NET File Uploading
File upload and download are much simpler tasks in ASP.NET than in classic
ASP, thanks to the extensive .NET Framework class library. While file
upload in ASP.NET is as easy as retrieving an HTML form value, file
download is still a bit tricky.

Dear Reader,
The O'Reilly Photoshop Cook-Off is simmering away on our Digital Media
site. But what the heck is O'Reilly doing sponsoring a Photoshop contest?
A few years ago, I too would have echoed that thought. But things have
changed.
What was once solely the kingdom of geeks, O'Reilly Media has expanded
into a publishing company that wants to bring that same fire and curiosity
to digital photography, music, HDTV, and video. Our assumption for years
was that if we found something interesting, we'd publish a book or post
an article online. Now we ask the question: Is this a book or a PDF?
Should we write an article or produce a podcast? What would our audience
want to see?
The Photoshop Cook-Off is designed to apply that same O'Reilly spirit to
Adobe's venerable image editor. If you'd like to hack a photo the same
way you do your operating system, then please, go see what this cook-off
is about.

*** O'Reilly Network Top Five Articles Last Week ***
1. What Is Web 2.0
Defining just what Web 2.0 means (the term was first coined at a
conference brainstorming session between O'Reilly and MediaLive
International, which also spawned the Web 2.0 Conference), still engenders
much disagreement. Some decry it as a meaningless marketing buzzword,
while others have accepted it as the new conventional wisdom. Tim O'Reilly
attempts to clarify just what we meant by Web 2.0, digging into what it
means to view the Web as a platform and which applications fall squarely
under its purview, and which do not.
<http://www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html>
***
2. Rolling with Ruby on Rails
The Ruby community is abuzz about Rails, a web application framework that
makes database-backed apps dead simple. What's the fuss? Is it worth the
hype? Curt Hibbs shows off Rails, building a simple application that even
non-Rubyists can follow.
<http://www.oreillynet.com/pub/a/onlamp/2005/01/20/rails.html>
***
3. How Shellcodes Work
Buffer overflow problems are well-known. Fewer people know how exploits
can help attackers execute their malware through buffer overflows and
other holes. Peter Mikhalenko walks through the construction and
refinement of a shellcode to show how they work so that you can protect
your machines.
<http://www.oreillynet.com/pub/a/linux/2006/05/18/how-shellcodes-work.html>
***
4. Ajax on Rails
XMLHttpRequest and Ruby on Rails are two hot topics in web development. As
you ought to expect by now, they work really well together. Curt Hibbs
explains the minimal Ajax you need to know and the minimal Ruby you need
to write to Ajax-ify your Rails applications.
<http://www.oreillynet.com/pub/a/onlamp/2005/06/09/rails_ajax.html>
***
5. 6. 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? He
thinks so. In the second of two parts, Curt completes his example Rails
application in merely 47 lines of code.

The Second Half of Buffer Overflows
LINUX NEWS FROM O'REILLY NETWORK
----------------------------------------
The Latest from http://www.linuxdevcenter.com and http://ONLamp.com
=================================================================

=================================================================
Welcome to the Linux newsletter. Just as Linux is the heart of the
GNU/Linux operating system, so is the term "Linux" a stand-in for the
huge, multi-decade corpus of free and open source software. Here's what
ONLamp.com and the other O'Reilly Network sites had to say about it this
week.
HTTP is a stateless protocol, much to the chagrin of everyone who's ever
written a web application. There are ways to get around this, however.
There are also at least two different places where you need different
behavior: sessions and state. This week, WASP's Brian Fioca explains the
differences between the two and shows good ways to handle both, using PHP
as his example:
<http://www.onlamp.com/pub/a/php/2006/05/18/managing-sessions-and-state.html>
By now, plenty of people understand the particular security hole known as
a buffer overflow. Certain C-level programming constructs make it
possible for an attacker to trick a remote computer into executing
arbitrary code. Yet do you understand what that arbitrary code is and how
it works? Peter Mikhalenko walks through the creation of a shellcode used
to demonstrate a vulnerability. With this knowledge, you can prove
security problems on your own machines with code much more trustworthy
than a binary downloaded from a very shady place online:
<http://www.linuxdevcenter.com/pub/a/linux/2006/05/18/how-shellcodes-work.html>
In weblogs this week, your editor spent yet more time refactoring an aging
Perl web application. At last, he finally finished fixing the node tests
and has started to manipulate the code itself:
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_19.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_20.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_21.html>
Robert Pratte considered the serious business use of Perl:
<http://www.oreillynet.com/onlamp/blog/2006/05/of_oysters_and_perls_or_perl_i.html>
Steve Mallett decided to become a Japanese schoolgirl (or at least an
alpha technology junkie):
<http://www.oreillynet.com/onlamp/blog/2006/05/were_all_japanese_schoolgirls.html>
Your editor revealed how to befriend an open source project on MySpace:
<http://www.oreillynet.com/onlamp/blog/2006/05/befriend_a_floss_project_on_my.html>
Curtis Poe resurrected Sapir-Whorf to discuss features missing from
programming languages:
<http://www.oreillynet.com/onlamp/blog/2006/05/sapirwhorf_is_not_a_klingon.html>
Andy Oram visited Jitterbit, a free software business bringing integration
to medium-sized companies:
<http://www.oreillynet.com/onlamp/blog/2006/05/jitterbit_userdriven_integrati.html>
Dave Cross found an auction for the most offensive Perl t-shirt ever:
<http://www.oreillynet.com/onlamp/blog/2006/05/perl_is_my_tshirt.html>
Caitlyn Martin opined that she really wanted to like Gnome, but just
can't. Then the commenters weighed in:
<http://www.oreillynet.com/linux/blog/2006/05/taking_a_linuslike_attitude_to.html>
Carla Schroder found a great article about a great-grandmother becoming an
enthusiastic music sharer:
<http://www.oreillynet.com/linux/blog/2006/05/greatgrandmother_hoists_the_jo.html>
Tony Stubblebine started to invent a new Ruby gem search tool:
<http://www.oreillynet.com/ruby/blog/2006/05/what_do_you_want_from_your_rub.html>
Pat Eyler raved about using rcov to verify test coverage on Ruby
projects:
<http://www.oreillynet.com/ruby/blog/2006/05/eating_your_own_dogfood_1.html>
Brian Jones argued that LDAP is not a relational database:
<http://www.oreillynet.com/sysadmin/blog/2006/05/ldap_is_not_a_database.html>
That's it for this week.
Please note that the Linux newsletter is going on hiatus for two weeks
while your editor strenuously avoids work. In the meantime, console
yourself with the tips, tricks, and opinions of everyone else on ORN,
including the revitalized O'Reilly Radar:

Carson Workshops: Getting Started with Rails
Taught by Geoffrey Grosenbach, May 25th 2006, NYC Learn how to get rockin'
with Ruby on Rails by one of the world's leading Rails developers.
http://www.oreilly.com/go/carson_rubyonrails
================================================================
ONLamp.com and Linux Devcenter Top Five Articles Last Week
1. Rolling with Ruby on Rails
The Ruby community is abuzz about Rails, a web application framework that
makes database-backed apps dead simple. What's the fuss? Is it worth the
hype? Curt Hibbs shows off Rails, building a simple application that even
non-Rubyists can follow.
<http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html>
***
2. How Shellcodes Work
Buffer overflow problems are well-known. Fewer people know how exploits
can help attackers execute their malware through buffer overflows and
other holes. Peter Mikhalenko walks through the construction and
refinement of a shellcode to show how they work so that you can protect
your machines.
<http://www.linuxdevcenter.com/pub/a/linux/2006/05/18/how-shellcodes-work.html>
***
3. 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? He
thinks so. In the second of two parts, Curt completes his example Rails
application in merely 47 lines of code.
<http://www.onlamp.com/pub/a/onlamp/2005/03/03/rails.html>
***
4. Ajax on Rails
XMLHttpRequest and Ruby on Rails are two hot topics in web development. As
you ought to expect by now, they work really well together. Curt Hibbs
explains the minimal Ajax you need to know and the minimal Ruby you need
to write to Ajax-ify your Rails applications.
<http://www.onlamp.com/pub/a/onlamp/2005/06/09/rails_ajax.html>
***
5. Using PC-BSD
A few user-friendly distributions of FreeBSD have appeared lately. PC-BSD
is one suitable for the corporate and home desktops, even those of users
unfamiliar with Unix. Dru Lavigne walks through the installation and
configuration of PC-BSD to provide a modern, powerful workstation.
<http://www.onlamp.com/pub/a/bsd/2006/05/11/FreeBSD_Basics.html>

Greetings, Perl hackers. This is the Perl newsletter, a bi-weekly mailing
to convince you, your friends, your family, your co-workers, and people
you meet in airports to visit Perl.com. Remember, if you haven't pointed
at least ten people to an article or weblog this week, you haven't done
your job!
Because some people take convincing, here's what's happened in Perl over
the last couple of weeks.
* Perl News in the Wild
The YAPC::Asia 2006 team published videos from their Tokyo meeting:
<http://www.archive.org/search.php?query=subject:%22yapc%22>
Parrot pumpking Leo Toetsch announced the release of Parrot 0.4.4,
"Feather," which includes new languages such as APL, Pheme, and something
called Perl 6:
<http://use.perl.org/article.pl?sid=06/05/15/0922235>
The YAPC::Eu 2006 team announced the official Birmingham conference
website:
<http://use.perl.org/article.pl?sid=06/05/12/1748220>
The Austrian Perl Workshop 2006 announced its dates: June 8 and 9:
<http://use.perl.org/article.pl?sid=06/05/11/0115245>
* Perl on ORN
Alex Gough has an odd job. He's the only programmer for about 500 miles.
Yes, there's Perl on every continent--he's in Antarctica. His problems
are about the same as yours though: collecting, analyzing, and charting
data. Here's how Alex uses Perl and the CPAN to make pretty pictures of
weather patterns with very little code:
<http://www.perl.com/pub/a/2006/05/04/charting-data.html>
Data::Dumper is a well-known tool for debugging and serialization. It
has some limitations, though, notably in its handling of subroutines
and closures as well as its all-at-once nature. Data::Dump::Streamer
is a newer module that does many of the same things better. Here's
how it works:
<http://www.oreillynet.com/onlamp/blog/2006/05/cpan_module_review_datadumpstr.html>
Patrick Michaud is the Perl 6 pumpking. Here's what he has to say about
his job in his own words:
<http://www.oreillynet.com/onlamp/blog/2006/05/people_of_perl_patrick_michaud.html>
Robert Pratte started his new ONLamp weblog by asking why Perl's
perception has waned for large, mission-critical applications:
<http://www.oreillynet.com/onlamp/blog/2006/05/of_oysters_and_perls_or_perl_i.html>
Perl Hacks co-author Curtis Poe wondered how to love a framework you've
never used:
<http://www.oreillynet.com/onlamp/blog/2006/05/how_to_love_a_framework_youve.html>
Andy Oram praised Volity, an open source platform for multiplayer
interactive games. Volity includes Perl bindings:
<http://www.oreillynet.com/onlamp/blog/2006/05/volity_opensource_interactive.html>
Patrick Michaud announced that Perl 6 runs on Parrot:
<http://www.oreillynet.com/onlamp/blog/2006/05/perl_6_on_parrot.html>
Dave Cross wondered who uses MVC frameworks in Perl after looking at all
of the frameworks in all of the other languages:
<http://www.oreillynet.com/onlamp/blog/2006/05/mvc_frameworks_in_perl.html>
Your editor continued his 30-post series (yep, still crazy), which
documents his work refactoring a legacy Perl system. Which system? Just
the one that runs Perl Monks.
This series quickly turned from "How to improve the code?" to "How to
refactor and improve tests." If you feel comfortable with Test::More and
other procedural test modules but find them less than capable of dealing
with large systems by themselves, Test::Class may prove a helpful
additional abstraction. How do you migrate tests though? Easy....

<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_21.html>
There will be no Perl newsletter next fortnight, as your editor will be on
holiday and no one in the office felt comfortable replacing him.
Good, bad, your editor is the one with the newsletter,

*** Featured Articles ***
Charting Data at the Bottom of the World
Alex Gough has a curious job. He's the only programmer for 500 miles at a
remote Antarctic research station. His problems are like your problems
too, though--gathering, manipulating, recording, and displaying data.
Here's how he uses several CPAN modules to make pretty charts and graphs
with almost no work.
<http://www.perl.com/pub/a/2006/05/04/charting-data.html>
***
Unraveling Code with the Debugger
Reading other people's code can be difficult, especially if you have no
idea what happens when and where. Understanding code flow is vital to
maintenance and bug fixes, but littering code with print and debugging
statements is tedious and prone to error. There's another way: use the
debugger! Daniel Allen demonstrates how to pinpoint a problem with Perl's
debugger.
<http://www.perl.com/pub/a/2006/04/06/debugger.html>
***
Using Ajax from Perl
The recently rediscovered Ajax technique makes the client side of web
programming much more useful and pleasant. However, it also means revising
your existing web applications to take advantage of this new power.
Dominic Mitchell shows how to use CGI::Ajax to give your Perl applications
access to this new power.
<http://www.perl.com/pub/a/2006/03/02/ajax_and_perl.html>
***
Advanced Subroutine Techniques
Subroutines seem like a basic building block of code. They're simple and
easy to understand and use, right? That's true--but there are a few
advanced techniques to make your code more maintainable and robust. Rob
Kinyon goes beyond making sense of subroutines to making subroutines work
for you.
<http://www.perl.com/pub/a/2006/02/23/advanced_subroutines.html>
***
Managing Rich Data Structures
Perl is so good at handling plain text files that it's seductively easy to
use them when you need something better. Yet sometimes using a
full-fledged database is just Too Much Work. If only Dave Baker had
written an article on using complex, persistent data structures with
MLDBM.
<http://www.perl.com/pub/a/2006/02/16/mldbm.html>
***
Debugging and Profiling mod_perl Applications
How do you use the debugger on a mod_perl application? How do you profile
an application embedded in a web server, with multiple child processes?
Don't worry. Where there's Perl, there's a way. Frank Wiles demonstrates
how to debug and profile mod_perl applications.
<http://www.perl.com/pub/a/2006/02/09/debug_mod_perl.html>

Dear Reader,
Welcome to another issue of XML.com.
Adrian Holovaty, one of the main developers of the hot new Python web
framework, Django, has one of the most interesting jobs around. He works
for the Washington Post doing, well, geek journalism. The Post pays him to
build journalistically interesting web applications. How cool is that?
Anyway, Adrian brings us an interesting thought-piece: what if news
publications on the web took the web more seriously and published more
dynamic stories? Adrian suggests several dynamic XML elements to make news
stories on the web more dynamic and more web-sensitive.

==================================================================
Greetings...
JavaOne is not a conference of particularly consistent messages, because
the Java world is so large, it's split into mutually incompatible niches.
This is healthy in many ways, as it encourages innovation and competition
even within the Java community--you say "20 different Ajax frameworks," I
say "a Swing client is still going to be nicer." This does, however, have
the disadvantage that there is little to unify the Java community, and
this really shows up in the JavaOne keynote, which is traditionally a
jumble of mixed messages and demos that appeal to a subset of the audience
while remaining utterly opaque to the rest. This year's opening general
session was no different, with a terrific Swing/Flickr/Google Maps demo
buried behind interoperability and BPEL demos that sent much of the crowd
fleeing (and gave the attendee to my left a chance to nap). Yet as much
as I liked the Swing team's "Aerith" demo, I'm sure there was a web tier
contingent that had utterly no use for it.
The one thing that unifies us is the language itself, so of course, the
big news from the general session was the evolution of Sun's answer to
"are you going to open source Java," with the new answer being "it's not a
question of if, but of how." Well, there's an implicit "when" in there
too; since Java's an open standard and a collection of JSR's, it's still
possible that someone other than Sun will create a free-as-in-speech Java
before Sun does, with Apache Harmony being the most obvious effort
currently underway.
Among the now-final Java EE 5's most prominent features is a new
persistence API defined by EJB 3 that is, in fact, available for use by
any Java SE or EE application. In "Standardizing Java Persistence API
with the EJB3 Java Persistence API," Debu Panda writes: "It simplifies the
use of transparent persistence by using metadata annotations and the
configuration by exception approach. Several application servers,
including Oracle Application Server 10g (10.1.3), Sun's open source
GlassFish Application Server, and JBoss Application Server 4.0, provide
early support for the EJB3 specification. With the Java EE 5.0 and EJB 3.0
specifications finalized, you'll soon see many leading application server
and persistence providers implementing EJB3 Java Persistence API."
<http://www.onjava.com/pub/a/onjava/2006/05/17/standardizing-with-ejb3-java-persistence-api.html>
Anil Hemrajani says that the established processes of Big Requirements Up
Front (BRUF) and Big Design Up Front (BDUF) seem like a good idea, but in
practice, they often lead to a waste of time and effort, and sometimes
lead to projects failing entirely. In the dev2dev article "Using Agile
Processes and Modeling to Build Enterprise Applications," he looks at the
approach of adapting less verbose and more reactive processes--agile
methodologies--to keep your project on track. "Since agile methods tend
to follow a common set of principles and values, one unpublished benefit
of agile methods is that you have the option to pick and choose from
various techniques and tailor them to your environment."
<http://dev2dev.bea.com/pub/a/2006/05/agile-modeling.html>
In this week's feature article from java.net, Mattias Arthursson and Ulrik
Sandberg provide relief for LDAP programmers in "LdapTemplate: LDAP
Programming in Java Made Simple." "LdapTemplate is a framework for
simpler LDAP programming in Java, built on the same principles as the
JdbcTemplate in Spring JDBC. It completely eliminates the need to worry
about creating and closing DirContext and looping through
NamingEnumeration."

*** Top Five Windows and .NET Articles Last Week ***
1. Run Mac OS X on a PC
You can get the best of both worlds--you can run the real Mac OS X on your
own PC. Wei-Meng Lee shows you how to run the Mac operating system on an
emulator called PearPC.
<http://www.windowsdevcenter.com/pub/a/windows/2005/01/18/PearPC.html>

2. Windows Server Hacks: Remotely Enable Remote Desktop
What to do when you need to enable Remote Desktop on a remote server?
Mitch Tulloch, author of Windows Server Hacks, walks you through the
steps.

should be a breeze. But it ain't necessarily so. Wei-Meng Lee shows you
how to do it.

4. Enhancing ASP.NET Pages with JavaScript
A sprinkling of JavaScript code can enhance the reach and responsiveness
of your ASP.NET web pages without sacrificing ASP.NET's secure,
server-based model for your coding. Matthew MacDonald, coauthor of ASP.NET
in a Nutshell, 2nd Edition, shows you how to use JavaScript in an ASP.NET
web page to perform three common tasks: showing a pop-up window, changing
control focus, and handling frame navigation. You can use these tricks to
quickly solve problems that have no native .NET solution.
<http://www.ondotnet.com/pub/a/dotnet/2003/09/15/aspnet.html>
***
5. ASP.NET File Uploading
File upload and download are much simpler tasks in ASP.NET than in classic
ASP, thanks to the extensive .NET Framework class library. While file
upload in ASP.NET is as easy as retrieving an HTML form value, file
download is still a bit tricky.

Writing PostgreSQL Functions with PL/pgSQL
One of the most powerful features of PostgreSQL is its support for

Real-Time Java: An Introduction
"Real-Time" Java doesn't mean "really fast," but it does mean "really

Real-Time Specification for Java and Sun's first implementation of the

Creating a Dual-Boot Windows XP and Ubuntu Laptop
Running a Windows-only laptop is hardly ideal for people who do
considerable work in the Linux environment. When Cygwin and ssh aren't

GNU/Linux machine. Here's how.

*** O'Reilly Network Top Five Articles Last Week ***
1. What Is Web 2.0
Defining just what Web 2.0 means (the term was first coined at a
conference brainstorming session between O'Reilly and MediaLive
International, which also spawned the Web 2.0 Conference), still engenders
much disagreement. Some decry it as a meaningless marketing buzzword,
while others have accepted it as the new conventional wisdom. Tim O'Reilly
attempts to clarify just what we meant by Web 2.0, digging into what it
means to view the Web as a platform and which applications fall squarely
under its purview, and which do not.

makes database-backed apps dead simple. What's the fuss? Is it worth the
hype? Curt Hibbs shows off Rails, building a simple application that even
non-Rubyists can follow.

3. Using PC-BSD

unfamiliar with Unix. Dru Lavigne walks through the installation and

LINUX NEWS FROM O'REILLY NETWORK
----------------------------------------
The Latest from http://www.linuxdevcenter.com and http://ONLamp.com
=================================================================
Carson Workshops: Getting Started with Rails
Taught by Geoffrey Grosenbach, May 25th 2006, NYC
Learn how to get rockin' with Ruby on Rails
by one of the world's leading Rails developers.
http://www.oreilly.com/go/carson_rubyonrails
=================================================================
Hello, Linux newsletter readers. If you have an interest in open source
and free software administration, advocacy, development, news, and usage,
read on. (If not, maybe we'll throw in a recipe next time.) Here's what's
new in the ONLamp world this week.
Longtime ONLamp readers know that the *BSD operating systems get good
press, even if they don't necessarily always get their fair share of
desktop users. FreeBSD Basics author Dru Lavigne wants to change that.
This week, she's written "Using PC-BSD" to introduce one of two
user-friendly, desktop-ready FreeBSD distributions. No kidding:
<http://www.onlamp.com/pub/a/bsd/2006/05/11/FreeBSD_Basics.html>
Despite the claims of some web programming toolkits, the database is a
great place to put some types of business logic; not only is it much
faster, but the database keeps these constraints in one place even (and
especially) if multiple applications use the single database. You'd go
crazy if you had to do all of this in SQL, though, so various RDBMS's
support various user-defined function languages. David Wheeler introduces
PostgreSQL's PL/pgSQL and shows how to write simple but powerful
user-defined functions:
<http://www.onlamp.com/pub/a/onlamp/2006/05/11/postgresql-plpgsql.html>
In weblogs this week, your editor spent yet more time refactoring the
tests for an aging Perl web application. There is much to learn:
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_16.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_17.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_18.html>
He also reviewed the CPAN module Data::Dump::Streamer:
<http://www.oreillynet.com/onlamp/blog/2006/05/cpan_module_review_datadumpstr.html>
... and then found a great GDC talk about test-driven game development:
<http://www.oreillynet.com/onlamp/blog/2006/05/making_better_games_with_tdd.html#comments>
Jeremy Jones reviewed Ubuntu's Dapper Drake Flight 7:
<http://www.oreillynet.com/onlamp/blog/2006/05/ubuntu_dapper_flight_7_minirev.html>
New ONLamp weblogger Curtis Poe pontificated about AI programming:
<http://www.oreillynet.com/onlamp/blog/2006/05/lemonade_stands_and_stupid_mov.html>
... then questioned DDJ's new love for Ruby on Rails:
<http://www.oreillynet.com/onlamp/blog/2006/05/how_to_love_a_framework_youve.html>
Juliet Kemp growled about an Iptables bug when trying to block brute-force
password attempts:
<http://www.oreillynet.com/linux/blog/2006/05/iptables_recent_module_bug.html>
Geoffrey Grosenbach suggested going solo as a full-time Rails developer:
<http://www.oreillynet.com/ruby/blog/2006/05/go_solo_as_a_fulltime_rails_de.html>
Derek Sivers found that Ruby's block passing worked just as he expected:
<http://www.oreillynet.com/ruby/blog/2006/05/passing_blocks_to_gsub_of_cour.html>
Anton Chuvakin announced a Log Management Summit (and called it "very fun"):
<http://www.oreillynet.com/sysadmin/blog/2006/05/log_management_summit.html>
Tom Adelstein reminisced about LDAP to remind administrators that their
jobs are about users:
<http://www.oreillynet.com/sysadmin/blog/2006/05/we_still_have_enterprises_infr.html>
Wow, that's a lot of stuff. It's a good thing this weekly mail goes out
to help you filter through it all.
One cool upcoming article shows how to build self-healing network services.
Stay cool until then,

Dear Reader,
Welcome to another issue of XML.com.
A few weeks ago we published a piece from Dave Hoover on building web apps
with the Canvas. Now Dave's back to explain how to use Google's new
ExplorerCanvas to build cross-platform, interactive web applications.

==================================================================
Greetings...
Garbage collection is great until you crash a plane or irradiate a local
populace because GC blocked the process that was supposed to adjust the
ailerons or vent the radioactive steam. That's why the old Java license
statement made you explicitly warrant that you wouldn't use Java for
operating aircraft, nuclear power plants, or other devices whose failure
would be potentially lethal. "Real-Time" Java deals with this problem by
eliminating the unpredictability of garbage collection, meaning your
program can expect a defined level of responsiveness, and you can know
whether this is enough to fly your plane.
"Real Time" doesn't mean "real fast." In Peter Mikhalenko's "Real-Time
Java: An Introduction," the author takes a close look at the Real Time
Specification for Java (JSR 1) and a recent implementation from Sun.
"Real-time Java offers a much more reliable and predictable scheduling
mechanism, memory handling methods, different memory models, a more
predictable threading and synchronization model, asynchronous event
handling, and high-resolution time handling. It makes predictable
execution the first priority in all trade-off decisions, sometimes at the
expense of typical general-purpose computing performance measures. This is
what real-time means."
<http://www.onjava.com/pub/a/onjava/2006/05/10/real-time-java-introduction.html>
If you're working with AJAX you've reduced bandwidth by sending just
needed data as XML rather than requesting a whole new page--but are you
making unnecessary requests? Bruce Perry says "Making HTTP requests
willy-nilly from AJAX applications is almost never a good idea or design
decision. The server side of the equation may not be able to handle the
flood of requests. The client side of the AJAX application may have some
of its requests time out or abort, which will disrupt the user experience
that is meant to be AJAX's strength." In the xml.com article "An AJAX
Caching Strategy," Bruce shows how to tighten up your code.
<http://www.xml.com/pub/a/2006/05/03/an-ajax-caching-strategy-prototype.html>
"If you have been in the IT field for a while, you can't help but get the
feeling of deja vu when you hear vendors pitching new technologies. If the
buzz and hype around Service Oriented Architecture (SOA), makes your head
spin, you are not alone." Nick Simha tries to cut through the hype and
get back to a useful understanding of SOA in the dev2dev article "SOA: Are
We Reinventing the Wheel?"
<http://dev2dev.bea.com/pub/a/2005/08/soa.html>
In this week's article from java.net, Thomas Kuenneth takes a first look
at one of Mustang's most prominent features in "Scripting for the Java
Platform." "One of the exciting new features of Java Standard Edition 6
will allow the tight integration of Java and scripting languages through a
standard Java Scripting API. In this article I will take a closer look at
how the current Mustang beta implements the underlying JSR-223 (Scripting
for the Java Platform) and introduce you to its classes and interfaces."

*** Top Five Windows and .NET Articles Last Week ***
1. Run Mac OS X on a PC
You can get the best of both worlds--you can run the real Mac OS X on your
own PC. Wei-Meng Lee shows you how to run the Mac operating system on an
emulator called PearPC.
<http://www.windowsdevcenter.com/pub/a/windows/2005/01/18/PearPC.html>
***
2. Windows Server Hacks: Remotely Enable Remote Desktop
What to do when you need to enable Remote Desktop on a remote server?
Mitch Tulloch, author of Windows Server Hacks, walks you through the
steps.
<http://www.windowsdevcenter.com/pub/a/windows/2004/05/04/serverhacks_remote.html>

3. Getting Your Bluetooth Headset to Work in XP
With Bluetooth support built into SP2, getting a Bluetooth headset to work
should be a breeze. But it ain't necessarily so. Wei-Meng Lee shows you
how to do it.
<http://www.windowsdevcenter.com/pub/a/windows/2005/07/05/bluetooth.html>
***
4. Enhancing ASP.NET Pages with JavaScript
A sprinkling of JavaScript code can enhance the reach and responsiveness
of your ASP.NET web pages without sacrificing ASP.NET's secure,
server-based model for your coding. Matthew MacDonald, coauthor of ASP.NET
in a Nutshell, 2nd Edition, shows you how to use JavaScript in an ASP.NET
web page to perform three common tasks: showing a pop-up window, changing
control focus, and handling frame navigation. You can use these tricks to
quickly solve problems that have no native .NET solution.
<http://www.ondotnet.com/pub/a/dotnet/2003/09/15/aspnet.html>
***
5. ASP.NET File Uploading
File upload and download are much simpler tasks in ASP.NET than in classic
ASP, thanks to the extensive .NET Framework class library. While file
upload in ASP.NET is as easy as retrieving an HTML form value, file
download is still a bit tricky.

Dual Boots and Smarter Pointers
LINUX NEWS FROM O'REILLY NETWORK
----------------------------------------
The Latest from http://www.linuxdevcenter.com and http://ONLamp.com
=================================================================
Carson Workshops: Getting Started with Rails
Taught by Geoffrey Grosenbach, May 25th 2006, NYC
Learn how to get rockin' with Ruby on Rails
by one of the world's leading Rails developers.
http://www.oreilly.com/go/carson_rubyonrails
=================================================================
Welcome to the Linux newsletter, everyone. This weekly mailing is a
transparent plea for you to read, read, read the latest articles and
weblogs on the O'Reilly Network related to the whole world of open source
and free software.
If you don't know pointers, you don't know C. (Your editor learned more
than he ever wanted to know about cross-platform function pointer
portability this weekend.) If you don't know pointers well, your C++ will
suffer. Manually managing dynamic memory in C++ can be difficult unless
you work with the system. Part of that is understanding the Resource
Acquisition Is Initialization idiom. Part of it is taking advantage of
smart pointers to free you from subtle, once-in-a-while failures. Julio
M. Merino Vidal explains the problems and demonstrates the solutions in
"Smart Pointers in C++":
<http://www.onlamp.com/pub/a/onlamp/2006/05/04/smart-pointers.html>
Alex Gough has an odd job. He's perhaps the only Perl programmer for 500
miles. Yet when the winds come up (and not too far up), his colleagues at
the South Pole want to go kite surfing. How does a Perl hacker at the
bottom of the world know when it's time to go out and have some fun? By
making pretty graphs of temperatures and wind speeds and other weather
conditions from lots of sensors. Here's what it's like to write code in
Antarctica:
<http://www.perl.com/pub/a/2006/05/04/charting-data.html>
Notebook computers generally start life with Windows XP sprawled across
their hard drives. For people who prefer the free and unfettered life,
this is not ideal. Cygwin can make Windows somewhat more palatable, but
there's nothing quite like actual Unix on your notebook. Kevin Farnham
recently made Ubuntu and Windows XP work together. Here's how he made his
laptop dual-boot:
<http://www.linuxdevcenter.com/pub/a/linux/2006/05/08/dual-boot-laptop.html>
In weblogs this week, your editor continued to refactor an aging Perl web
application in public, learning new things and revealing his own gradual
competence:
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_13.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_14.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/refactoring_everything_day_15.html>
He also interviewed Patrick Michaud, Perl 6 pumpking and announced
Patrick's supersecret current project--Perl 6 running on Parrot:
<http://www.oreillynet.com/onlamp/blog/2006/05/people_of_perl_patrick_michaud.html>
<http://www.oreillynet.com/onlamp/blog/2006/05/perl_6_on_parrot.html>
Jeremy Jones found Guido van Rossum blessing Django:
<http://www.oreillynet.com/onlamp/blog/2006/05/guido_points_out_django_is_gai.html>
He also tried PyDev again, preferring it over Eclipse:
<http://www.oreillynet.com/onlamp/blog/2006/05/a_glance_at_pydev.html>
Dave Cross wondered why people planning to build new MVC-based web
applications don't seem to be choosing Perl:
<http://www.oreillynet.com/onlamp/blog/2006/05/mvc_frameworks_in_perl.html>
Caitlyn Martin revived a pair of ancient 133MHz laptops with small Linux
distributions:
<http://www.oreillynet.com/linux/blog/2006/05/atticware_reving_ancient_littl.html>
Carla Schroder praised internet radio:
<http://www.oreillynet.com/linux/blog/2006/05/bah_humbug_tinny_digital_music.html>
Andy Oram wondered if Red Hat might benefit most from Sun's relaxing the
distribution requirements for Java:
<http://www.oreillynet.com/etel/blog/2006/05/might_red_hat_benefit_most_fro.html>
Caleb Tennis made the case against Python (or any other language) as the
default "just get into programming" language:
<http://www.oreillynet.com/ruby/blog/2006/05/the_case_for_python.html>
James Britt explained his plan for introducing Ruby last weekend:
<http://www.oreillynet.com/ruby/blog/2006/05/ruby_at_code_camp.html>
Your editor pondered the notion of agile database administration:
<http://www.oreillynet.com/databases/blog/2006/05/reducing_the_cost_of_database.html>
That sums up this week. Be sure to check back on the various open sourcey
sites through this week to see what's new. If you leave a comment on any
one of these weblogs, you even have a chance to shape what's on the site
next week! How cool is that?

ONLamp.com and Linux Devcenter Top Five Articles Last Week
1. Ajax on Rails
XMLHttpRequest and Ruby on Rails are two hot topics in web development. As
you ought to expect by now, they work really well together. Curt Hibbs
explains the minimal Ajax you need to know and the minimal Ruby you need
to write to Ajax-ify your Rails applications.
<http://www.onlamp.com/pub/a/onlamp/2005/06/09/rails_ajax.html>
***
2. Smart Pointers in C++
C++ is a powerful language that allows fine-grained control over almost
all aspects of your program. Of course, low-level code has its
disadvantages too. Manual memory management can be complex and difficult
to get right. Fortunately, the RAII idiom and smart pointers can help you
write correct and efficient code. Julio M. Merino Vidal demonstrates.
<http://www.onlamp.com/pub/a/onlamp/2006/05/04/smart-pointers.html>
***
3. Managing Disk Space with LVM
Linux's Logical Volume Manager (LVM) allows you to create virtual disk
partitions out of one or more hard drives. This makes it easy to manage
growth in filesystems. Combined with RAID, it provides a nearly unbeatable
way to keep your files safe and available. Bryce Harrington and Kees Cook
show how to configure LVM, how to combine it with RAID, and how to use it
on desktop machines too.
<http://www.linuxdevcenter.com/pub/a/linux/2006/04/27/managing-disk-space-with-lvm.html>
***
4. OpenBSD 3.9: Blob-Busters Interviewed
Every six months, the OpenBSD team releases a new version of their OS.
OpenBSD 3.9 is here. Federico Biancuzzi recently interviewed the core
developers about new features and improvements, as well as their
principled stand against shipping binary-only blobs in place of actual
drivers.
<http://www.onlamp.com/pub/a/bsd/2006/04/27/openbsd-3_9.html>
***
5. PHP Form Handling
If your PHP program is a dynamic web page (and it probably is) and your
PHP program is dealing with user input (and it probably is), then you need
to work with HTML forms. David Sklar, author of Learning PHP 5, offers
tips for simplifying, securing, and organizing your form-handling PHP
code.

==================================================================
Dear Mac Reader,
One of the problems I had with the old "Switcher" ads was their dash of
arrogance. I'm not really comfortable with putting the other guy down in
order to look better. So I held my breath when the latest parcel of TV
ads, "Get a Mac," hit the airwaves.
This group of six ads is different than the previous bundle. Instead of
one switcher, they pair a hip but likable Mac user with a nerdy but
likable Windows guy. They are each in their own worlds, but exhibit
tolerance for the other's. My takeaway on the spots is this: if you find
yourself in the Windows world by default, but it isn't really resonating
with you, there's an attractive alternative--Mac. If you're happy with the
clock and calculator as your bundled apps, then you'll probably want to
stay where you are.
Clean, entertaining, and to the point. I think Apple has done a nice job
with these spots. If you'd like to watch them yourself, go to this page on
the Apple site:

Until next time,

Dear Reader,
Welcome to another issue of XML.com.
Experts differ about the performance impact of AJAX applications. Sure,
AJAX apps make more HTTP requests of servers, but these days we know a lot
about optimizing HTTP requests. One of the most important aspects of that
optimization process is clever use of HTTP caching. Bruce Perry's latest
article explores a caching strategy for AJAX applications.

Greetings...
One thing I really enjoy in articles is the idea of combining pieces in
surprising ways. In the Java community, we benefit from a massive library
of built-in and standard-extension functionality, with an even larger
universe of open source and commercial code that we can then tie into.
For my money, the first step of many development processes should be to
Google to see if someone's already done what you need to do, or close
enough. Connect the dots, do stuff faster.
Consider the requirement to manage not only objects and documents, but
also their history, perhaps tracking not just the deltas, but the time,
date, user, and reason for each change. Sure, you could develop your own
tables and logic for this, but doesn't it sound like a problem that's
already been solved? Come to think of it, doesn't it sound like what a
source code repository does? In "Configuration Management in Java EE
Applications Using Subversion," Swaminathan Radhakrishnan suggests letting
Subversion do this work for you, by connecting your Java EE application to
a Subversion repository by way of the JavaSVN library.
<http://www.onjava.com/pub/a/onjava/2006/05/03/j2ee-configuration-management-with-subversion.html>
If you're a Java ME developer, there's a good chance you've written at
least one game for the platform, and that means you've surely faced the
challenge of creating and presenting engaging sound within the tight
limitations of the mobile phone platform. Peter Drescher offers a number
of novel approaches in the Digital Media article "Could Mobile Game Audio
BE More Annoying?!", which is adapted from his presentation at the recent
Game Developers Conference.
<http://digitalmedia.oreilly.com/2006/04/26/could-mobile-game-audio-be-more-annoying.html>
Real-time Java doesn't mean fast, it means predictable, so much so that
you can count on things. "The WebLogic Real Time server (WLRT) provides a
lightweight infrastructure with low latency for event-driven applications.
It is intended for use in highly competitive environments where
performance is key and therefore every millisecond counts. For example,
certain industries such as telecommunication or insurance require that
transactions be performed with very low latency within given timeframes.
Trying to implement this with standard Java most likely will fail because
of the unpredictable pause times caused by the garbage collection
process." Markus Eisele explores this platform in the dev2dev article "An
Introduction to WebLogic Real Time."
<http://dev2dev.bea.com/pub/a/2006/04/introduction-wlrt.html>
In our feature article from java.net, Tim McCune introduces some much
appreciated and much debated "Exception-Handling Antipatterns." "In this
article, we'll discuss some fundamental concepts about the different types
of Java exceptions and their intended uses. We'll also cover basic logging
concepts, especially as they relate to exception handling. Finally,
instead of prescribing what to do, we'll focus on what not to do, and take
a look at a dozen common exception-handling antipatterns that you are
almost certain to find somewhere in your code base."

5. ASP.NET File Uploading
File upload and download are much simpler tasks in ASP.NET than in classic
ASP, thanks to the extensive .NET Framework class library. While file
upload in ASP.NET is as easy as retrieving an HTML form value, file
download is still a bit tricky.

Dear Reader,
Brian McConnell has just published a three-part series on our Emerging
Telephony site about using IT to help prepare for a possible pandemic.
Besides plenty of good general advice for businesses, schools, and
organizations on how to think about and prepare for such a crisis, one of
the articles provides some very specific and actionable instructions on
how an organization can very cheaply set up a large-scale teleconferencing
system using open source tools (Asterisk and Gizmo). The ability for
companies to do this on their own is relatively new, and I haven't seen
any other articles detailing it the way Brian does.
I highly recommend you take a look at the follow pieces:

1. What Is Web 2.0
Defining just what Web 2.0 means (the term was first coined at a
conference brainstorming session between O'Reilly and MediaLive
International, which also spawned the Web 2.0 Conference), still engenders
much disagreement. Some decry it as a meaningless marketing buzzword,
while others have accepted it as the new conventional wisdom. Tim O'Reilly
attempts to clarify just what we meant by Web 2.0, digging into what it
means to view the Web as a platform and which applications fall squarely
under its purview, and which do not.

5. Managing Disk Space with LVM
Linux's Logical Volume Manager (LVM) allows you to create virtual disk
partitions out of one or more hard drives. This makes it easy to manage
growth in filesystems. Combined with RAID, it provides a nearly unbeatable
way to keep your files safe and available. Bryce Harrington and Kees Cook
show how to configure LVM, how to combine it with RAID, and how to use it
on desktop machines too.

=================================================================
Hello, Linux newsletter subscribers. Prepare yourself for yet another
rapid-fire tour of the new goodness in the world of ONLamp.com and the
Linux DevCenter.
Managing disk space seems like a thankless, dull job--people love to
create and store more and more data, hardware always improves, and
hardware always eventually dies. Managing mount points and migrating
shares and rebuilding arrays are just too much work. When Bryce
Harrington and Kees Cook said, "We like this LVM stuff" your editor paid
attention. They've written "Managing Disk Space with LVM" to demonstrate
how building your partitions atop Linux's logical volume manager (an
abstraction above physical disks) makes upgrading and migration much, much
easier. Your editor might even manage disks sometime:
<http://www.linuxdevcenter.com/pub/a/linux/2006/04/27/managing-disk-space-with-lvm.html>
Right on schedule, the OpenBSD team released the latest world-changing
release: 3.9. The image for this release is blob-busting. That is,
OpenBSD stands on its principles never to ship big, useless, unfree
binary-only blobs to make drivers work. Federico Biancuzzi recently
interviewed several OpenBSD developers about this philosophy in practice,
as well as new features, and upcoming plans:
<http://www.onlamp.com/pub/a/bsd/2006/04/27/openbsd-3_9.html>
In weblogs this week (and have you noticed that the weblog icon comes from
your editor's first book?), your editor continued his series on
refactoring a large web application:
<http://www.oreillynet.com/onlamp/blog/2006/04/refactoring_everything_day_10.html>
<http://www.oreillynet.com/onlamp/blog/2006/04/refactoring_everything_day_11.html>
<http://www.oreillynet.com/onlamp/blog/2006/04/refactoring_everything_day_12.html>
Victor Rodriguez interviewed Guillaume Cottenceau, creator of Frozen Bubble:
<http://www.oreillynet.com/onlamp/blog/2006/04/people_of_perl_guillaume_cottenceau.html>
Jeremy Jones pledged allegiance to a diverse use of technology:
<http://www.oreillynet.com/onlamp/blog/2006/04/i_pledge_allegiance.html>
Brian Jones recommends not forgetting the database when designing a
PHP application:
<http://www.oreillynet.com/onlamp/blog/2006/04/designing_a_databasedriven_php.html>
Google's Summer of Code 2006 started accepting student applications:
<http://www.oreillynet.com/onlamp/blog/2006/05/summer_of_code_2006_opens_for.html>
Carla Schroder installed some SATA drives to help with her digital editing
in Linux:
<http://www.oreillynet.com/linux/blog/2006/04/digital_editing_in_linux_sata.html>
Lyz Krumbach announced the formation of the Ubuntu-Women group:
<http://www.oreillynet.com/linux/blog/2006/04/ubuntuwomenorg_launched_1.html>
Tim O'Reilly queried several Web 2.0-related companies about their use
of databases:
<http://www.oreillynet.com/databases/blog/2006/04/database_war_stories.html>
Tom Adelstein yet again took employers to task for horrible, awful, very
bad, no good job descriptions:
<http://www.oreillynet.com/sysadmin/blog/2006/04/employers_get_a_grip_on_your_j.html>
Steve Mallett found a nice Japanese translation of Rolling with Ruby on
Rails, Part 2:
<http://www.oreillynet.com/ruby/blog/2006/04/japanese_translation_of_rollin.html>
Pat Eyler admits an addiction to watching Ruby and other projects fix
their Coverity-revealed defects:
<http://www.oreillynet.com/ruby/blog/2006/04/addicted_to_coverity_1.html>
The conferences team kept the MySQL Users Conference weblog up to date:
<http://www.oreillynet.com/conferences/blog/mysql_users_conference/>
This includes presentation files:
<http://conferences.oreillynet.com/pub/w/45/presentations.html>
... as well as James Duncan Davidson's official photographs:
<http://www.flickr.com/photos/x180/sets/72057594112748158>
Upcoming article topics include natural language programming languages,
bots, and how to use C++ without sanity rolls.
Until then,

ONLamp.com and Linux Devcenter Top Five Articles Last Week
1. Managing Disk Space with LVM
Linux's Logical Volume Manager (LVM) allows you to create virtual disk
partitions out of one or more hard drives. This makes it easy to manage
growth in filesystems. Combined with RAID, it provides a nearly unbeatable

2. OpenBSD 3.9: Blob-Busters Interviewed
Every six months, the OpenBSD team releases a new version of their OS.
OpenBSD 3.9 is here. Federico Biancuzzi recently interviewed the core
developers about new features and improvements, as well as their
principled stand against shipping binary-only blobs in place of actual
drivers.
<http://www.onlamp.com/pub/a/bsd/2006/04/27/openbsd-3_9.html>

3. Clever Tricks with MythTV
Building your own personal video recorder means that you can avoid
manufacturer- or broadcaster-enforced restrictions. That's not all,
though. John Littler presents some clever ideas on what you can accomplish
with a MythTV box, some free time, and a little work.
<http://www.linuxdevcenter.com/pub/a/linux/2004/12/29/mythtv_hacks.html>
***
4. New Vulnerability in OpenSSH
A new vulnerability in OpenSSH can be exploited by a local attacker to
execute arbitrary code with the permissions of the root user. Noel Davis
also covers problems in OpenBSD, wmtv, Auto Nice Daemon, NetDynamics,
Xitami Web server, libgtop_daemon, xtel, Lotus Domino, OpenServer's
setcontext and sysi86, SuSE's Postfix installation, and fml.
<http://www.linuxdevcenter.com/pub/a/linux/2001/12/10/insecurities.html>
***
5. Ajax on Rails
XMLHttpRequest and Ruby on Rails are two hot topics in web development. As
you ought to expect by now, they work really well together. Curt Hibbs
explains the minimal Ajax you need to know and the minimal Ruby you need
to write to Ajax-ify your Rails applications.
<http://www.onlamp.com/pub/a/onlamp/2005/06/09/rails_ajax.html>

Hello, everyone. Have you ever stared in horror at the television set (or
computer screen, perhaps) as an announcer advertised that the upcoming
episode of your favorite sitcom is "A very special episode"? Your horror
stems from knowing (having heard that particular phrase before) that your
sitcom is about to air a message episode that, say, abusing drugs or
alcohol or getting cancer is just bad. It's never funny.
Fortunately, this is just an average Perl.com newsletter, no more or less
special than every other every-other-week mailing. Besides that, we don't
have an announcer.
* Perl News in the Wild
The Perl Review interviewed O'Reilly editor, TPF president emeritus,
Parrot and Punie hacker, and small press publisher Allison Randal about
all of those jobs (but not microphasic sleep):
<http://www.theperlreview.com/Interviews/allison-randal-20060412.html?up>
Allison Randal also announced the public review of the second version of
the Artistic License as well as the upcoming Perl Contributor Agreement:
<http://use.perl.org/article.pl?sid=06/04/20/2042256>
Josh McAdams and the YAPC::NA team released the schedule for this year's
conference in Chicago:
<http://www.yapcchicago.org/the-schedule/>
Audrey Tang, Allison Randal, Jesse Vincent, and lots of other Perl 6 and
Pugs people came up with a new plan for the licensing of Pugs:
<http://pugs.blogs.com/pugs/2006/04/licensing_clari.html>
Perl Hacks went to the printer.
Perlcast interviewed professional author Steve Oualline, whose most recent
book is Wicked Cool Perl Scripts:
<http://perlcast.com/2006/04/18/interview-with-steve-oualline-of-wicked-cool-perl-scripts/>
* Perl on ORN
Your editor continued his 30-post series (yep, still crazy) that documents
his work refactoring a legacy Perl system. Which system? Just the one
that runs Perl Monks.
This series quickly turned from "How to improve the code" to "How to
refactor and improve tests." If you feel comfortable with Test::More and
other procedural test modules but find them less than capable of dealing
with large systems by themselves, Test::Class may prove a helpful
additional abstraction. How do you migrate tests though? Easy....
<http://www.oreillynet.com/onlamp/blog/2006/04/refactoring_everything_day_7.html>
<http://www.oreillynet.com/onlamp/blog/2006/04/refactoring_everything_day_8.html>

Quick, who gets paid to hack on Perl? No, not to hack Perl--to hack on
Perl itself? Precious few people. Yet progress progresses and patches
patch and bugs unbug and time moves on and every few months, there's a new
stable release of Perl that's better than the previous version. Stable
pumpking Nicholas Clark recently lamented this situation (hey, they're all
volunteers) and wondered if other languages face this in a post on the p5p
mailing list:
<http://www.oreillynet.com/onlamp/blog/2006/04/maintaining_a_programming_lang.html>
Did you know you can write games in Perl? You certainly can. Guillaume
Cottonceau stunned the world by creating one of the best-loved open source
games, Frozen Bubble. In Perl. Victor Rodriguez recently interviewed him
about everything Perl:
<http://www.oreillynet.com/onlamp/blog/2006/04/people_of_perl_guillaume_cottenceau.html>
Dave Cross apologized for helping to write the useful Template Toolkit
book. Why? Because spammers apparently are using Template Toolkit to send
their messages. Badly.
<http://www.oreillynet.com/onlamp/blog/2006/04/spamming_badgers.html>
That's it for this fortnight. Upcoming interviews include Patrick
Michaud, with a very special announcement. (No, no, no, not THAT kind of
very special announcement.)
Best,

*** Featured Articles ***
Unraveling Code with the Debugger
Reading other people's code can be difficult, especially if you have no
idea what happens when and where. Understanding code flow is vital to
maintenance and bug fixes, but littering code with print and debugging
statements is tedious and prone to error. There's another way: use the
debugger! Daniel Allen demonstrates how to pinpoint a problem with Perl's
debugger.
<http://www.perl.com/pub/a/2006/04/06/debugger.html>
***
Using Ajax from Perl
The recently rediscovered Ajax technique makes the client side of web
programming much more useful and pleasant. However, it also means revising
your existing web applications to take advantage of this new power.
Dominic Mitchell shows how to use CGI::Ajax to give your Perl applications
access to this new power.
<http://www.perl.com/pub/a/2006/03/02/ajax_and_perl.html>
***
Advanced Subroutine Techniques
Subroutines seem like a basic building block of code. They're simple and
easy to understand and use, right? That's true--but there are a few
advanced techniques to make your code more maintainable and robust. Rob
Kinyon goes beyond making sense of subroutines to making subroutines work
for you.
<http://www.perl.com/pub/a/2006/02/23/advanced_subroutines.html>
***
Managing Rich Data Structures
Perl is so good at handling plain text files that it's seductively easy to
use them when you need something better. Yet sometimes using a
full-fledged database is just Too Much Work. If only Dave Baker had
written an article on using complex, persistent data structures with
MLDBM.
<http://www.perl.com/pub/a/2006/02/16/mldbm.html>
***
Debugging and Profiling mod_perl Applications
How do you use the debugger on a mod_perl application? How do you profile
an application embedded in a web server, with multiple child processes?
Don't worry. Where there's Perl, there's a way. Frank Wiles demonstrates
how to debug and profile mod_perl applications.
<http://www.perl.com/pub/a/2006/02/09/debug_mod_perl.html>
***
Test-Driving X11 GUIs
Is GUI testing as difficult as it seems? Maybe not, with the right testing
libraries. George Nistorica shows what X11::GUITest can and can't do to
make your Unix and Unix-like applications more robust.
