For a client project, I am setting up a number of Open Source tools to facilitate team communication and cooridination:

Apache HTTP Server 2.2.4

Cruise Control 2.7

Eclipse 3.3 (Europa)

MediaWiki 1.10.1

MySQL

PHP 5.2.3

Python 2.5.1

Roller 3.1

Subclipse 1.2.3

Subversion 1.4.4

Trac 0.10.4

WebSVN 2.0

Yesterday I installed WebSVN at the client site - and missed a key line in the config.php - so this morning, with a fresh pair of eyes - I quickly spotted it and it is operational. Simple, clean, efficient.

I'm currently researching a possible comptability issue with the Apache 2.2 and Subversion 1.4 release - related to the mod_dav_svn.so


I thought these links might have been the solution to the compatibility problem - but it appears that I have further research to do

This link may provide some potential solutions - with recompiled mod_dav_svn.so links.

It was a problem with how permissions were handled in APR's stat calls
on windows and it produced strange errors inside Subversion's working
copy code. It was fixed (I believe) in revision 425620 of APR, and
backported to APR 1.2.x in revision 425621.

I'm pressed for time tonight...so this will be a brief post of some interesting links. One of my current client projects involves developing an Enterprise / Service Oriented Architecture. As a natural consequence of that effort, the question of versioning must be addressed. Here are a few links related to that problem space:

W3C Publishes an Update to Guide to Versioning XML Schema 1.1

w3.org Guide to Versioning XML Languages using new XML Schema 1.1 features

w3.org: Extending and Versioning Languages: Strategies

xml.com: Extensibility, XML Vocabularies, and XML Schema

xfront.com: XML Schemas: Best Practices

xfront.com: XML Schema Versioning

David Orchard: Extensibility, XML Vocabularies, and XML Schema

I came across this blog today: plentyofcode.com (Programming Resources, News and Ideas). Wow - what a treasure trove of links.

I had an interesting meeting today with representatives of Software AG, and had some good discussions covering some of the tools that they offer for rapid development of Web Services to access legacy applications. The scope of today's discussions mostly focused on challenges around integrating legacy mainframe applications into a Service Oriented Architecture (SOA). ApplinX and EntireX were two products in particular that were discussed today.

SYS-CON Media Announces the 2007 Java Developer's Journal Readers' Choice Awards

I've recently made some progress in introducing some Open Source tools into a client's software development environment - most notably, I've been able to gain some mind-share around adoption of Eclipse, Subversion, and Cruise Control. Small steps - but potentially huge long-term significance in terms of eventually reducing the cost of IT's overall budget. The client had considered adopting Microsoft SourceSafe as the primary repository for all project artifacts - for use by developers as well as business analysts and end-users. At a quoted price of roughly $400-500 per seat for the appropriate Microsoft SourceSafe client software - and a potential 25% adoption across an organization 16,000 personnel - I figure I've saved my client over $1.8M in initial cost - and $360K in annual maintenance cost - just by the introduction of Subversion.


I'm doing some research for a client on how they can integrate their legacy mainframe systems (IBM CICS, Adabas, VSAM, ORACLE, COBOL, etc.) into a new SOA Enterprise Service Bus (ESB). The IONA Artix 5 software includes facilities for integration with CICS mainframe environments - but IBM's 3.1 release of CICS also included enhancements that support SOA Web Services:

IBM's SOA-centric CICS

IBM CICS Web Services

Application Transformation with
CICS Transaction Server for z/OS V3.1

IBM Enterprise Architect Kit for SOA

Beautiful Code: Where leading programmers explain how they find unusual and carefully designed solutions

A lot going on these days...

I'm beginning an evaluation of IONA's Artix 5 release of their SOA Enterprise Service Bus (ESB).

As a small mental diversion (and just for fun), I've started doing some research on algorithms for solving Sudoku puzzles. This is of interest as a possible seed to form some ideas as the basis for developing a utility library that would provide methods for solving scheduling, optimization, planning, time table, and resource allocation problems based on Constraint Programming / Local Search approaches.

I'm also interested in exploring approaches to developing Rich Internet Application (RIA) user interfaces - using Flash / Flex technologies. A few resource links:

Creating rich Web service clients with Flash and Flex

Flex Wiki

Flex 2 SDK

Wikipedia ActionScript

Programming ActionScript 3.0

I've also recently completed a preliminary analysis for a client of the integration capabilities and challenges for the following applications:

Primavera's P6 suite (Project Manager, Contract Manager, Operational Data Store)

OpenText LiveLink Enterprise Content Management (ECM)

WinEstimator

Ares/PRISM
