+Hi All,
+
+apologize me for the gap time :-/
+
+the "duplicate grass installation" gived me some problems.
+Fixed the gdal-grass driver problems (thanks to William!!!) when multiple grass installation are finded
+now the problem come up with subprocess when i use the grass.py function
+
+the error is a bit weird beacouse it sometimes works and sometimes get me a subprocess error
+
+^^^ this only on Osx ...  on linux all goes fine.
+
+
+... so : hard solution, i erased an exrternal hd and installed osx from scratch with only one grass version(7) i haven't finished to reinstall all the needed SW
+
+
+back to coding ...
+
+going ahed with my coding ... what i do this week :
+
+- worked a lot to have a better gui.
+  to have a more usable app. i switched from Qwidjet() to Qmainwindow() so now i'm able to use more widjet like menubar etc... (i know this are cosmetics things ;-)
+
+- worked on the kml export, not uploaded yet into the svn
+  i have kml export working for point line and polygon, but i haven't yet it working on polygon that has inner+outher boundaries.
+  it use py-gdal to have acces to the layer feature
+
+  the export parameters are : 
+
+  colors (line,label,polygon)
+  alpha-chanell(colors)
+  line width
+  altitude mode
+  icons 
+
+  label name and height can be setted from a field attribute
+
+  (studing the kml standard)
+
+   i'm including the layer attributes in the "kml data description", but my plain is to insert , in the kml attribute data, 
+   the results of v.what + r.what (for points and/or polygon's centroid)
+  for line i think is not usefull .. maybe leght and layer attributes can be good as information.
+
+  the layers to be queried are the layer in the active mapset 
+  (in the gui i'm adding a tree with layer's names, each layer will be checkable so all the checked layer will be passed to the query)
+
+  i need to add yet the capabilites to create png file for raster legend so we can the kml export to create "kml screen overlay"
+  i think to use the png monitor in grass to produce the image or other solution .. i need to investigate 
+
+-  wrotin build documentation about my linux environment.
+   starting from a linux live cd distro (sidux) i done an "how to install" (apt-get & configure notes) for all the sw i'm using
+   so i create a virtualcd based on virtualbox i can distribuite to every one want help me to test the project 
+   (the project has immense options of development so suggestions on which    feature is to prefer to an other one 
+    or you have a feature that is possible to include in it and and i haven't tinked yet)
+
+-  On the next week the OssimDev Team will have a meeting, so i'm preparing a report with case-test to face the ossm-gdal-grass   raster rendering.
+
+== ==
+
+== Report 3  ==
+
+Little notes :
+
+Restored my OS,
+
+for grass on osx i'm using version 6.4
+(the 7 can works, but some time the build fais, so to have a more stable development
+i'm switching to 6,4 binary version, so it is more easy for osx user to test the code)
+
+on linux i'using grass7 (there are difference in the module import for grass, so i'll use "try: except"
+to get the code running for grss 6.4 and 7)
+
+
+Coded :
+
+fixed the polygons exporte to kml so now hole in polygons hare andled
+firex some gui behavioure .. a window too much big, so i done a recode of the gui code
+
+- preparing a different web-map widjet, based on ka-map2
+ this can give some enanchement like :
+ - ability to crteate a mapfile on the fly, generated reading the grass mapset layers
+ - better refresh of gps signal
+
+- done a report about the grass-raster rendering, this tasks will be faced the next week,
+ i have exam on 16 june so the incoming week my Soc works will be slowly
+ (i hope all goes well) then i'm planning to go to bolsena meeting where i'll spend
+  a full dept week to code.
+
+here some screenshoot  of the gui (yet prototipe) :

+http://www.geofemengineering.it/data/gps.png
+
+for who is intersted in testing, debug :
+
+-  notes about the installation of the needed software can be etracted from :
+
+http://wiki.osgeo.org/wiki/GFOSS.it_Live_DVD_Install
+
+
+done a virtual machine with needed sw,
+but my ftp reject it :-(
+so i don't know where to upload it
+(this is for who is intersted in testing purpose, but has problems / or do not want touch his system)

+== Report 4  ==
+
+Hi All, 
+
+here the 4-th report for my project :
+
+In the last week, after some coding i can see that he main-app file was too much long 
+that is no good beacouse the code is not easy readable.
+
+doing some  test, i can see the threaded class "joystick and gps tools"  
+consume a lot of cpu-resource
+
+i decided to do a complete revision on the code :
+
+- extracted some function and class from the main file
+  and store it in separate files (the code results more readable,
+  and each tools can be easy re-used out-side the main app)
+
+- done a complete revision on the trheaded class, 
+  now the trhead are colled only when they really needs
+  i also added in the joystick code a line used in pygame 
+  to reduce cpu usage when possible.
+
+
+The results code is more fast and readable.
+
+In the last week i also worked on :
+
+- a query tool to ask information on grass layer (both raster and vector)
+  it runs r.what + v.what on  a list of selectable layers avaiable in the active grass-mapset.
+
+- initial test about the grass code to produce "legend images"  for raster layers
+  this is needed to produce kml screen overlay
+
+- create a blog page for the project to describe the project
+
+
+what to do  the next week :
+
+- separate each tool in separate files produce some (minor) code issue, i need to learn how to send
+  a message from one widget to an other one (e.g. create connections bettween different tools) 
+  if some one has pyqt knowledge i have some questions for him ;-)
+  
+- rework the web-map based tool using kamap2 (it will consists in a web-gis based on a mapfile produced on the fly, it read the layer to render from a list of grass layer, so i'm coding an interface to produce it)
+  
+- i'll be in Bolsena for the osgeo hacking event i'll try to receive feedback, suggestion for a full coding-week
