Pre-Alpha RC1

June 2nd, 2008 at 22:46 · Filed Under Ada, At Work, Blogging, Days in My Life, Software Development, Web · Comment 

I am in the midst of getting the KazeServer to roll out. During this pre-Alpha RC1 stage, works have been a little pressured especially cleaning up parts of the codes to make it neater and more efficient. A number of factors are also affecting during pre-Alpha stage.

One of them is the gnat Ada compiler issue on Ubuntu Hardy Heron or 8.04. Hardy comes with gnat-4.1 with a number of packages not added. Without these packages, I can’t build AWS-2.3. So, I have to roll out Alpha RC1 on Mac OS X until Ubuntu Intrepid or 8.10 with gnat-4.3 is released (hopefully with gnat-4.3 by October). I have another option which is I have to move to Debian Etch with gnat-4.1 but including the libaws-2.2.

libaws-2.2 is a pre-built library for AWS on Debian Etch. I am developing using gnat-4.4 and AWS-2.3 on Mac OS X. Moving to Debian Etch means I am downgrading the version of gnat and AWS and I feel a little skeptical about it. This is one thing I hate most, version inconsistency among the Linux distro.

After talking to my friends on this matter, it looks like I have few choices but to target on Mac OS X for the moment considering the tasks of installing and get the Debian Etch up and a whole lot of uncertainties in gnat-4.1 and AWS-2.2.

Can’t build AWS in Ubuntu

May 26th, 2008 at 9:44 · Filed Under Ada, Computing, Linux, Software Development · 1 Comment 

About two weeks ago, I installed Ubuntu Hardy Heron in VMware Fusion on my MacBook (running Leopard). After some playing around with Ubuntu on my MacBook, I began to install software components such as the Ada compiler so that I could do testing on my MacBook without switching to the Ubuntu box.

I am working on a web-enabled application developed with AWS (Ada Web Server). This application is developed on Mac OS X. Building and testing on mac OS X has no problem at all. To compile the source on Ubuntu, I need AWS. So, I tried to install AWS packages from Ubuntu but found only broken dependencies. Then I decided to build one myself. The build has failed because the gnat (Ada compiler) from Ubuntu is 4.2. It lacks two Ada packages, a-calfor.ad[sb] (Ada.Calendar.Formatting) and a-catizo.ad[sb] (Ada.Calendar.Time_Zones). AWS depends on these to build.

I posted to comp.lang.ada and AWS list. It looks like I have no choice but to bootstrap gnat-4.3 myself or install from Ubuntu Intrepid or wait for the next Ubuntu release of gnat-4.3.

China’s proven world class competency

April 13th, 2008 at 13:20 · Filed Under Ada, China, Computing, Humanity, Linux, Software Development, Web · Comment 

During the snow hazard in China this February, the Chinese government had successfully managed the natural disaster and crisis with much professionalism in such a short period of time. According to an unconfirmed source, the Chinese government managed to develop a Disaster Management System in just 5 days. 75 software engineers from the Chinese military worked around the clock for 5 days to bring up a web based Disaster Management System to collect, manage, disseminate, coordinate, and to provide command and control to the military disaster relieve team during the recent snow hazard.

The system was developed using Ada, AWS (Ada Web Server) with a little of PHP and Perl. The system deploys a MySQL database running on Linux. The system is hooked up to air-borne SAR (Synthetic Aperture Radar) for real-time acquisition of landscaping information in snow hazard affected area to help assessing the damage of rail ways, roads, housing and forest. The Chinese army engineering company was dispatched by the system to areas in need of assistance.

I have yet to receive further details of how the system works and probably will not. Anyway, that shows the Chinese ability and responsiveness in dealing with natural disaster. Hail China!
