O.K., O.K, O.K. :-)
we can discuss all issues again and again, but in fact I am sure nobody
will give up own position.
It is turning to one of these neverending discussions with trivial results.
Different experiences - different prefferences. Let's just enjoy
alternatives we have.
Neither Windows nor Linux are our religions, nor I am enemy of Bill or
having a party with Linus. I am enjoying both and I do trust neither of
them by 100%. There are many programming and GIS sollutions available
for any OS (multiplatform) anyway. Eventualy I'm tired of paying for
every movement of own research activities and all that "talking money"
stuff.
Here are short comments on general security tips thread that I started.
Sorry if you find them trivial:
1) I'm sure many people still have old problems (it's enough to look at
logs of my firewall to imagine what is a real situation around). 2)
Automatic windows updates is not the best solution at all. I've seen XP
machines that become unusable after such an update. 3) Yes, Linux
distributions offer possibility of automated update (and the GUI for
it). In Red Hat just join Red Hat network and
a) you will get all information about all updates targeted to your
machine's configuration
b) there is an icon on a task bar which changes it's color when a new
update is available. Click the icon and your will know what updates are
available and chose your RH system to be automaticaly updated. You may
also switch this feature off anytime.
though, let's go back to the GIS...

I am sure you know GRASS http://grass.itc.it/ and plenty of add-ons for
it for virtualy any purpose you may need for your GIS projects. Also a
freeGIS http://freegis.org/index.en.html project. There are also many
free single-purpose or specialized GIS packages (also for MS Windows) like
Microdem http://www.usna.edu/Users/oceano/pguth/website/microdem.htm ,
3DEM http://www.visualizationsoftware.com/3dem.html,
fractal landscape simmulator-Terragen http://www.planetside.co.uk/terragen/,
SPRING GIS http://www.dpi.inpe.br/spring/english/
that emerged as results of research and development activities in the
universities.
and everybody knows this place: http://software.geocomm.com/index.html

Note that the task is not to painfully assemble a total of one and a half million lines of code over the course of ten years, because then the result is obsolete when complete. The task is to sustain huge, focussed development throughput that can virtually move mountains within a single year. Otherwise, one cannot advance the state of the art in GIS.

I do not think 1 000 000 lines/year is a measure of quality. It is the
algorithms that make the software run. One can write 100 rows for the
task that is solvable with 20. Also there are algorithms that take 1
minute to do what is possible to accomplish in 10 sec. Moreover -
a huge amount of these rows are produced automaticaly by any favorite
"VisualSomething" to produce a GUI. While a "real algorithmic GIS" part
of it occupies just a relatively small part of the binary space.
Am I using "obsolete" GIS software ?
Well, is it important if it can easily accomplish everything I need ?...

>Such concentration of force in elite, interactive applications has thus far not been achieved in Linux markets because there is insufficient incentive given the microscopic size of the Linux interactive market. The only market big enough to incent such concentration of force in the face of great risk is the Windows market.

--------------------------------------------------------
Linux markets are still in a stage of growth.
But, why not to enter both (or all available) GIS markets at once ?
Why can't we create GIS tools that work everywhere. There are many free
options and tools we have to accomplish this task. PHP, Perl, Java, XML
etc.. are building bricks available for fr
