Until then, please go to www.wr-man.net/rwsd to access the database application and the weblog of Tanzania Rural water Supply Department.]]> General remarks http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=33 Sun, 9 Apr 2006 22:06:24 +0200 http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=32
In the next step, we installed the RWSD database site also under Fedora 3, the new location will be accessible under www.wr-man.net/rwsd. This is functional since 3rd February 2006!

However, for a certain period the RWSD database will be available under both URLs (i.e. also under the current www.disk-world.net).

That site is based on the development work made for RWSD, but with a few but essential differences:

• The database is PostgreSQL instead of MySQL


• Geographic data used by MapServer are stored in the same PostgreSQL database and not in external shapefiles


• Based on available monitoring data, charts are produced by the web server according to user specifications


• The webserver runs under Fedora 3 instead of Red Hat 7 - because the old Linux distribution did not permit a newer version of PostgreSQL

I am looking for a solution.

In the meantime, you can log in as 'guest' pw: 'guest'. This is an old account and allows full editing. For security reasons, I just made a backup ...

OK - I found the solution in the nucleusfaq http://faq.nucleuscms.org/item/42. New users can now make new entries - and the guest account has been disabled ;-)

To become a new user, just enter a comment here!

No, you are not becoming a new member automatically. The administrator will add new members automatically. Thus, in your comment, you have to explain briefly why you are applying for membership, i.e. your professional position or your field of interest.]]> Bug reports http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=29 Fri, 21 Oct 2005 15:44:21 +0200 http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=28 PHP Hypertext Processor). The comprehensive documentation of the PHP program source code for the RWSD database application has been uploaded now to this web site and is available online now. This documentation has been produced in the following steps:

1. Goce added comments to the original PHP code. This was the most work intensive part


2. Using an open source program called phpDocumentor the documentation with all its links was generated as CHM-helpfile


3. Klaus decompiled the CHM-helpfile, corrected wrong links (caused by a bug in phpDocumentor), added a header page, modified the table of contents in “HTML Help Workshop” and recompiled it again.


4. Than Klaus used a shareware program called chm2web to transform the CHM-file into an online help system with a nice navigation

On demand, I can also email the latest CHM-file as a single file - to have all documentation together in a single file.]]> General remarks http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=28 Tue, 18 Oct 2005 00:50:42 +0200 http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=27 Quantum GIS is still in beta phase (the current version is 0.7) but already fairly stable and really fast even when processing large data sources. Some features (like the semi-transparent display of raster files, dashed borders of polygons and “halos” around labels) are features users always requested for ArcView and only got it finally in ArcGIS – nor now with Quantum GIS.

Quantum GIS can not only read ESRI Shapefiles and Coverages as well as MapInfo files but also geographic data saved in PostgreSQL. I am currently experimenting with PostgreSQL as it appears also the ideal data storage for our Mapserver. The “on-the-fly-projection” for vector files is another feature supported by QuantumGIS. It is also supported by ArcGIS but not by the old ArcView 3.x. Quantum GIS is available for Windows, Linux (Debian, Mandriva, Suse), Apple and Free BSD.

Last not least, for Quantum GIS a number of plug-ins are available which permit advanced data management and modelling tasks interesting fo the assessment and management of natural resources.

But beware! The openModeller Wizard may not load, and SPIT (the Shapefile to PostGIS Import Tool) may spoil your ArcGIS data sources. I received first an error message under SPIT “problem inserting features from file” and than the data were also not any more acessessible from ArcGIS. Only after I loaded them from ArcView and exported them to a new shapefile I could import them to PostGIS and load them into ArcGIS as well.]]> General remarks http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=27 Mon, 26 Sep 2005 11:27:34 +0200 http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=25

Since June 2005, we are working on a comprehensive documentation of the program code. During that exercise (which included the writing of comments into the PHP code), an error was made which produced the following message when requesting a table output:

“Fatal error: Call to a member function on a non-object in
/etc/httpd/htdocs/common/controls/ctrl_reportbands.php on line 227”

As soon as the error was noticed by the developer team it has been corrected. But one question remains: are there no users in Tanzania or anywhere on this planet, who had noticed that error before and could have it reported in this forum?

Our virtual servers that are based on them are running Apache web server and MySQL data base; these are responsable to generate the pages you are seeing on the domain www.disk-world.de. Unfortunately, Apache and MySQL did not restart automatically but had to be started manually, causing times of being not accessable.

Today (30th June 2005) new scripts were put on our virtual server. Now, after every reboot of the server Apache and MySQL should restart automatically.]]> General remarks http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=23 Thu, 30 Jun 2005 15:31:43 +0200 http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=22
The structure of the database is such that “data on scheme level” and “relation of resources to schemes” depend on the definition of schemes (with address and related villages).

Maintaining these relations is now controlled by so-called “foreign keys”. Databank users with administration rights can test this by trying to delete some scheme that is already referenced in some of the scheme detail tables. The user should be informed about the inconsistencies that the requested data operation will cause. Pay a special attention on the treatment of resources and pumps. The FK validation prevent modification of PK (primary key) and deletion of a referenced row.]]> General remarks http://www.wr-man.net/rwsd/nucleus/index.php?blogid=2index.php?itemid=22 Tue, 31 May 2005 09:42:22 +0200
