News and Editorials
A new version (1.4) of a document extraction tool known as HappyDoc
[15]has been released. "HappyDoc is a tool for extracting
documentation from Python source code. It differs from other such
applications by the fact that it uses the parse tree for a module to
derive the information used in its output, rather that importing the
module directly. This allows the user to generate documentation for
modules which need special context to be imported."
This is an interesting concept, there must be a ton of useful
information embedded in the source code of software projects. Code
analysis is by no means a new field, but the creation of documentation
from code analysis could be an area that is worthy of further study.
Documentation could be derived from code using several approaches:
* Looking at the code's structure: The structure of a program
reveals a lot of how the code works. Happydoc works on this
principal, and there are, no doubt, many other examples of this
kind of code.
* Analyzing the code's data: Data structures reveal much about the
function of code, software that collects this information and
presents it in a useful way could be helpful in writing
documentation.
* Filtering out the code's comments: A lot of the information
embedded inside of comments is very specific to the code that it
describes, possibly to the point of uselessness for generating
documentation. Comments can also be out of date or misleading.
Nonetheless, looking at all of the comments in a body of code as a
whole could be a useful method for deriving some useful
documentation from code. Trouble areas in the code would likely
stand out. In fact, the comments in the Linux kernel source code
were analyzed and a lot of colorful language was revealed.
Through the use of Perl, Python, or other high level languages, it
should be possible to write a program that looks at a piece of code
from all of these angles and produces a pile of output, some of which
could be useful for writing documentation. Documentation is famous for
being left as the last task, or never finished. Having automated tools
for assisting in the generation of documentation could go a long way
towards making the job less painful. Such an effort might even uncover
a new bugs.
Audio

issue features a new document, the Remote Serial Console HOWTO, and
numerous updated documents. (Thanks to David C. Merrill.)
Embedded Systems
Embedded Linux Newsletter for Mar. 22, 2001 (LinuxDevices.com). The
weekly [18]Embedded Linux Newsletter from LinuxDevices.com is
available. This week's coverage included A 6-part special feature on
Midori Linux, GtkFB -- GTK+ for the Linux framebuffer, and details
about Sharp's new Linux-based PDA.
Filesystem Software
Common threads: Learning Linux LVM, Part 1 (IBM developerWorks). In
this article from IBM developerWorks site, the concepts behind
[19]Linux LVM (Logical Volume Management) are introduced, showing
readers how to get the latest kernel patches and tools installed on a
system. "What happens if you need to expand a filesystem so that it
spans more than one hard drive, or what do you do if you need to
dynamically expand or shrink a volume's storage capacity while
allowing Apache to continue to serve Web pages? In a highly available,
dynamic environment, a basic partition resizer just won't work. For
these and other situations, Logical Volume Management is an excellent
(if not perfect) solution."
Network Management
OpenNMS Update. The [20]OpenNMS update for March 20, 2001 is
available. This issue covers project status; new offices, new servers,
new build stuff, upcoming road shows, and more.
Just in time for this week's LWN, the [21]OpenNMS update for March 27,
2001 is also available. Topics this week include preparation for the
0.7.2 release which just may show up late next week, new core team
members, report generation, and more.

software development with the Ruby language.
Software Development Tools
Optimizing your machine for your needs (IBM developerWorks). Teodor
Zlatanor shows us some tricks for [23]setting up a Linux user account
for software development in an IBM developerWorks article. "After
customizing tcsh, Enlightenment, Eterm, and Emacs for a Java and
Perl-oriented programming environment, Teodor shows us the
configuration of his desktop in Linux. It is optimized for a Java and
Perl programming setup, but doubtless other programmers will find many
useful tips." We feel obliged to add some Unix trivia, the rc suffix
for .cshrc, .bashrc etc stands for Run Command.
State Map Compiler Version 1.0 beta 4 released. A beta version of the
State Map Compiler [24]has been released. "SMC takes a state map
description (stored in a .sm file) and generates State pattern classes
in a target language (C++, Java or Tcl currently supported). SMC is a
console based app written in Java 1.2 which means SMC can run anywhere
Java 1.2 (or better) can run."
Web-site Development
Squishdot 1.0 released. Squishdot 1.0 has been [25]released. Squishdot
is a Slashdot-like system built on Zope. This release includes an
important security fix; sites currently using squishdot should
certainly upgrade. (Thanks to Navindra Umanee).
Midgard 1.4.1 released. Version 1.4.1 of the "Midgard Content
Management and Application Serving Suite" has been [26]released. This
release, codenamed 'bifrost,' includes PHP4 support and a number of
other goodies.
Measuring Web traffic (IBM developerWorks). Andrei Malacinski, Scott
Dominick, and Tom Hartrick delve into the topic of web server logfile
analysis in a two-part IBM developerWorks article. [27]Part 1 covers
the general ideas and strategies and [28]part 2 goes into the nitty
gritty details of log file content analysis.
Window System Software
The Pango connection: Part 1 (IBM developerWorks). IBM developerWorks
[29]introduces Pango, the next generation text rendering library that
will be delivered with GTK+ 2.0. "Pango is an open-source framework
for the layout and rendering of internationalized text, including
right-to-left scripts and scripts such as Tamil where glyphs are
context-sensitive. Not surprisingly, Pango uses Unicode characters
internally (represented using UTF-8), and Pango's interfaces also use
UTF-8."
The People behind KDE: Michael Haeckel. [30]KMail hacker Michael
Haeckel is the focus of the latest "People behind KDE" feature. "KMail
is a central tonality of the KDE harmony. Part of the team of
developers who invest work and passion into this interesting project,
Michael Haeckel hacks away, making great contributions to the KDE
Project".
KDE Developer's Checklist. Jeff Tranter has put together a [31]KDE
Developer's Checklist with a ton of useful advice for porting software
to KDE. "KDE developers, especially new ones, can easily overlook some
tasks or features when developing applications or making changes to
existing ones. KDE is a large system and, while much of the
information exists somewhere, there is no one comprehensive set of
development standards."
Word Processors
LyX Development News for March 28, 2001. The March 28, 2001 edition of
the [32]LyX Development News is available. This edition contains a
number of amusing awards such as the Asbestos Suit Award. Also

Securing systems: Using Java technology in high-stakes systems (IBM
developerWorks). Joseph Sinclair talks about [53]security issues
facing the development of Java based information systems. "As
J2EE-based systems become more prevalent, and sensitive data is more
commonplace, the ability to effectively secure and manage
Internet-accessible systems ceases to be a luxury and becomes a
necessity. This general overview -- the first in a series of articles
-- examines how Java technology can be used to secure systems in which
the consequences of mistaken identity can be particularly
destructive."
