Installing Adobe Air 2.6 on Linux Mint 13 ‘Maya’ (64 bit)

Hi all,

here you are a useful “how to” to install Adobe Air on linux mint ‘Maya’ 64 bit:

  1. Download the Adobe Air 2.6 runtime installer for Linux which can be found here.
  2. install a few things, by typing in “sudo apt-get install libhal-storage1 libgnome-keyring0 lib32nss-mdns“  <— lib32nss-mdns was the only file i didn’t have installed. It might be different for you.
  3. make sure libgnome-keyring0:i386 is installed with “sudo apt-get install libgnome-keyring0:i386
  4. link your 32bit to your /usr/bin with this command. “sudo ln -s /usr/lib/i386-linux-gnu/ /usr/lib/″
  5. make the AdobeAIRInstaller.bin executable with “sudo chmod +x AdobeAIRInstaller.bin
  6. run the installer with “sudo ./AdobeAIRInstaller.bin

This should start the installer and install it with no problems.

Thank you Chuck….


GeoServer Beginner’s Guide (not only for novice)

Let’w talk about a new book on Geoserver: a useful manual for everyone.Here’s my review:

“Who has had the idea of entitling this book “Beginner’s guide”? This manual is much much more! Actually, besides supplying beginners with the basics of GIS and Geoserver, it can well work as an operational manual at a more specialized level. Since several years I’ve been working with this software (Geoserver) for job, and therefore I have matured a certain experience; in the book I found some information on Geoserver that previously I could obtain only through several researches in websites and thematic forum. I’ve appreciated very much the “practical” sections and the multi-choices quiz that invite the reader to think again to what he has previously read and, possibly, to read it once more.

The section on GIS basics is very important because the given notions help in understanding and fully exploiting the potential of Geoserver; I’ve enjoyed very much to successfully execute on an ubuntu-like system the detailed and precise procedure for installing Geoserver and all necessary software. Chapters 3, 4 and 5 gradually introduce the reader into the secrets of the management interface and to the way of accessing and loading spatial data. Also in this case I’ve tried to execute the described procedures by following the tips of the authors: surprise! I’ve found myself perfectly comfortable both as an “absolute beginner” and as a GIS expert. The descriptions and the observations on the “WMS reflector” functionality are very useful, since this tool helps the user to publish spatial data according to his own needs.

Also in chapter 6 the approach is very “soft”, since it introduces the reader to the basics of the largely applied OGC standard; but then, gradually, the book checks the reader’s abilities with the practical section “time for action”, sums up the notions he has just learned with “What just happened?” and finally brings him to dare with the section “Have a go hero”.

In my opinion, from chapter 7 on, topics switch to an intermediate level: implementation of simple webgis applications, configuration of geowebcache software to enhance performances, description of REST interface to automatize tasks, up to the very important topic of security are treated. Nevertheless, the confidential tone, the numerous references to examples and practical procedures, together with the concepts learned in the previous chapters, allow even the less expert reader to try to implement and manage a simple spatial data infrastructure.

Chapters 11 e 12 are really appreciable: they list and describe the basics (and not only) for tuning Geoserver and enhancing its performances in enterprise environments, and how to manage “troubleshooting” also by means of several active “mailing lists”. I’ve been impressed by finding in about 30 well organized pages all the useful references, which makes this book resemble a real, easy-to-use and complete “practical handbook” To sum up, I think that this book is suitable and complete both for those who approach Geoserver for the first time and for those who work daily with this software.”

That’s all!  Good job!

IL SOFTWARE LIBERO PER GLI INGEGNERI – seminario di formazione e aggiornamento

Il 15 aprile scorso l’associazione Apriti Software! col sostegno dell’Ordine degli Ingegneri della Provincia di Cagliari e del DIEE – Dipartimento di Ingegneria Elettrica ed Elettronica della facoltà di Ingegneria di Cagliari, ha organizzato un seminario di formazione e aggiornamento sull’utilizzo di strumenti free/open source nell’esercizio della professione dell’ingegnere.

Installation of libreoffice 3.3 on Ubuntu 10.04 (Lucid)

In this article I want to share my experience with the installation of the Libre Office free software. First of all I just want to thank the document foundation. Iwish you good luck!!! for this great initiative.

Now this simply procedure (taken from the ubuntu forum):

1. Download LibreOffice from: LibreOffice Downloads;

2. Extract the file to ~/Desktop

3. Rename the file to libreoffice

4. Open Terminal and enter this command:

sudo dpkg -i ~/Desktop/libreoffice/DEBS/*.deb

5. Then enter the following command into Terminal:

sudo dpkg -i ~/Desktop/libreoffice/DEBS/desktop-integration/libreoffice3.3-debian-menus_3.3-9526_all.deb

The importance of being dynamic (for a WFS)

These are the results of a “personal” functionality comparison on some GIS desktop:

– web feature service:  Sardinia Region WFS (2000 objects limited)

– layer used: usoSuolo2008

Udig 1.2: AUTOMATIC load of the current map extent objects; AUTOMATIC new request during the navigation (zooming, pan, ecc.); preservation of the thematization; AUTOMATIC load of the web service intire list layer;

gvSIG 1.9: MANUAL load of the current map extent objects; MANUAL new request during the navigation (zooming, pan, ecc.);  NO preservation of the thematization; AUTOMATIC load of the web service intire list layer;

quantum GIS 1.3: NO load of current map extent objects; AUTOMATIC load of the web service intire list layer;


ESRI arcGIS 9.3.1: NO load of current map extent objects; NO loading intire list layer of the web service.


As you see with these requirements and these Web Feature Service charateristics the best GIS desktop that provide “dynamic WFS request funcionality” is Udig 1.2  followed by gvSIG 1.9, Qgis 1.3 and arcGIS 9.3.1.
