Development projects
News and Editorials
The latest [15]SourceForge update has been published. Among other
things, it states that none of the SourceForge staff were affected by
the layoffs at VA Linux.
SourceForge provides an incredibly useful service to the open-source
developer community, and VA Linux should be greatly thanked for that.
The current statistics show that around 16,000 projects are hosted
there. One has to wonder, however, if the community would not be
better served by a more decentralized model for the hosting of
open-source projects.
Having a large percentage of projects under development on a single
site tends to concentrate all of the risks in one place, whether they
are related to corporate troubles, network crackers, or legal attacks.
The news from VA concerning SourceForge is fairly reassuring, but it
makes one think about what would have happened if there had been staff
cuts in that area.
It might be time to consider the old adage: Don't put all of your eggs
in one basket.
Clusters
Linux-Cluster mailing list. Rik van Riel has created a [16]metalist
for Linux cluster projects in an effort to share infrastructure
between the multiple clustering projects currently underway.
Databases
Mini SQL 3.0 pre 1 released. Hughes Technologies [17]announced the
availability of Mini SQL 3.0 pre 1, also known as mSQL. See [18]the
release notes for details on the changes in this release, which
include a completely redone query engine.
aboutSQL: GROUP BY (ONLAMP.com). John Paul Ashenfelter continues his
series on SQL programming with an article that introduces the SQL
[19]GROUP BY directive.
Embedded Systems
A developer's perspective on PocketLinux (LinuxDevices.com). Part 5 of
a series from Jerry Epplin on the [20]status and history of Linux on
PDAs looks at Transvirtual's PocketLinux, the Java based solution for
handheld devices. "PocketLinux for the iPAQ uses the handhelds.org
kernel and builds a GUI platform on top of it. But PocketLinux,
provided by Transvirtual Technologies, is in a sense more ambitious
than the others, in that it is targeted toward development by both
programmers and non-programmers."
Network Management
OpenNMS Update, February 27th, 2001. The latest issue of the
[21]OpenNMS Update has been published. Highlights include updates to
the status of various projects and an early adopter program status.
PortMon 0.6 released. Version 0.6 of PortMon [22]has been released.
"PortMon is a port monitor program that keeps track of open ports on
servers to be sure they are still up and talking."
Science
Danforth Center's Kilo Cluster Helps Researchers Study the Building
Blocks of Life (Enterprise Linux). Enterprise Linux magazine [23]has
published an article about a Linux based Beowulf cluster that is being
used for genetic research. "Skolnick rejected RISC-based solutions as
being either too big, too slow or too expensive, and decided on a
Beowulf cluster using Intel Pentium III processors at 733 MHz, and
running the Linux operating system. And, he found he could afford a
system with 1,040 processors (520 nodes), giving him peak performance
of 335 Gflops."
Web-site Development
ht://Dig 3.20 b3 released. After nearly a year of inactivity, a new
version of the popular web site search engine, [24]ht://Dig 3.20 b3
has been released. [25]The release notes contain a long list of bugs
that have been fixed.
Announcing OpenFlow 1.0. Paolo Bizzarri [26]has announced the
availability of OpenFlow 1.0, an open-source workflow management
system. "OpenFlow is a workflow management system, written in Zope +
Python. It has been heavily based on the Chautauqua workflow."

Java
Writing multithreaded Java applications (IBM developerWorks). Alex
Roetter discusses [46]Java multithreaded applications in an IBM
developerWorks article. "A program or process can contain multiple
threads that execute instructions according to program code. Like
multiple processes that can run on one computer, multiple threads
appear to be doing their work in parallel. Implemented on a
multi-processor machine, they actually can work in parallel. Unlike
processes, threads share the same address space; that is, they can
read and write the same variables and data structures."
O'Reilly Network Launches Independent Java Web Site. O'Reilly [47]has
announced the creation of a new web site dedicated to Java,
[48]ONJava.com, that it claims will be an advocate for open source
software development in the Java community. The site will also cover
open source Sun initiatives like the Jakarta and JXTA projects under
the Apache open source license.

PHP
An Introduction to PHP (O'Reilly). John Coggeshall [53]introduces PHP
in an O'Reilly Network article. "At a fundamental level, PHP has all
of the features of a complete programming language (control
structures, repetitive tasks, and variables) but perhaps one of its
most powerful features is database access. With PHP it is possible to
access over 19 different types of databases and manipulate data within
those databases based on input from the user via a web page."
PHP Weekly Summary for February 26, 2001. The [54]February 26, 2001

updates to gnome-python, and an open-source port of Python to the Palm
Pilot.
Guido talks about nested scopes (python.org). Python.org has posted an
ongoing discussion about [58]Nested Scopes, a somewhat controversial
addition planned for Python that may break legacy code. "We have
clearly underestimated how much code the nested scopes would break,
but more importantly we have underestimated how much value our
community places on stability. At the same time we really like nested
scopes, and we would like to see the feature introduced at some
point."
XML-RPC for Python. Secret Labs has released [59]xmlrpclib 0.9.9, a
Python implementation of the XML-RPC protocol.
Dive Into Python Chapter 3. Chapter 3 of the online Python book Dive
Into Python [60]has been announced. This chapter covers classes,
exceptions, file handling, and more.

Convention Smalltalk [61]is available. "Generic Types are a solution
to the question: 'How do I reuse a collection interface with different
element types?'. More generally it is applicable anywhere where one
type serves as a parameter to another."

providing a home for Tcl development, stepping into the void created
