Thunderbird and Lightning

Install the following packages using Synaptic from menu System->Administration->Synaptic Package Manager

• thunderbird
• lightning-extension

Create and Publish a Calendar

1. Open Thunderbird and click on Calendar
2. Right click in the calendars list and create a New Calendar
3. Choose On the Network
4. Click on Next
5. Select format: iCalencard (ICS)
6. Insert location: http://localhost/phpicalendar/calendars/TestCalendar.ics
7. Click on Next
8. Provide a Calendar name: TestCalendar
9. Click on Next and Finish
10. Right click on the calendar that we have just created and click on Publish Calendar…
11. Insert URL: http://localhost/phpicalendar/calendars/TestCalendar.ics then Close

Thunderbird doesn’t provide any feedback, so check on the server that the calendar has been created properly

$ ls -l /var/www/phpicalendar/calendars/

You should see a `TestCalendar.ics` file.

Using Calendars from others PCs

To connect others client PCs to the same calendar, create a new calendar in Thunderbird in the same way as before, but there is no need to publish the calendar this time.

a month is gone since my last post and finally I can write again. The month of December has been very busy, we had a lot of work and then Ada has arrived.

I have some news and articles to write, I just need to find some time between bottles and nappies.

This method it use .cue files, which usually comes with the .flac ones.

First of all we need to install the following packages cuetools shntool flac. You can use Synaptic or this command in a terminal:

$ sudo apt-get install cuetools shntool flac

Now you can split the .flac audio file as follows:

$ cuebreakpoints file.cue | shnsplit -o flac file.flac

That’s all.

Now a little bit of theory,
… shnsplit is the program used to split tracks, while cuebreakpoints it reads the break-points from file.cue and pipe them to shnsplit.

Eclipse is a well known IDE interface which help programmers to develop their Java applications, but Eclipse is not only for Java programmers, as it can help PHP programmers as well by using the PHP Development Tools (PDT).

While searching on Internet I found several way to install Eclipse and PDT, so here I am going to tell you how I did it on my Ubuntu 7.10 Gutsy with PHP support. As I am a newbie on Eclipse I cannot tell you if it is the best way or that is error free. I only know that it worked for me, or at least Eclipse it started without any error message.

First you have to install the Sun Java Development Kit 5.0 (JDK) and Eclipse from Ubuntu repositories:


$ sudo apt-get update
$ sudo apt-get install sun-java5-jdk
$ sudo apt-get install eclipse

Now we have Eclipse installed and working, but there are a couple of problems, most important PDT is not installed as there’s no debian package yet. Second this is an older version, Eclipse 3.2.2 instead of the 3.3.0. I used this approach to assure that everything Eclipse needs is installed.

To add PDT you can use an automated installation of PDT available via the Eclipse Update Manager, but as we want to use the latest version and also keep things simple, you can download the PDT All-in-One package.

Personally I downloaded the Stable Build S20070910-RC1 under the ~/tmp directory, you can choose the release that you prefer. There is no really installation program so these are the commands that I used to install it under my home directory and to start Eclipse.

$ mkdir ~/opt
$ cd ~/opt
$ mv ~/tmp/pdt-all-in-one-incubation-S20070910_RC1-linux-gtk.tar.gz .
$ tar xzvf pdt-all-in-one-incubation-S20070910_RC1-linux-gtk.tar.gz
$ cd eclipse
$./eclipse


Optionally you can change the Gnome Menu link using, System->Preferences->Main Menu application.

Now you can start working with Eclipse and PDT just create a new PHP file or project, and code away.

So… What we should say now with these 3D effects in Ubuntu ?

Spiders on the Web,
Danilo

There are some new interesting features:

• Gnome 2.20
• 3D Desktop, Compiz Fusion is enabled by default but I think it needs a good graphic card
• Desktop Search, a deskbar applet is now included in the default configuration. It allows quick access to your common actions, including opening web bookmarks and searches, sending messages to your contacts, and more
• A wizard to install Firefox’s plugins
• … and a lot more

Today somebody told me that Linux it’s difficult and is good only for programmers. I replied that this is not true anymore, I saw a demo of what you can do with the 3D desktop that definitely we can say that Linux is good for anyone.

So I suggest you download the CD so you’ll check it out yourself.

Today, OpenOffice.org celebrates its 7th birthday. It was on 13th of October 2000 when Sun Microsystem founded what it is widely considered the most important open source productivity suite and one of the largest open source projects.

I worked daily with OpenOffice.org since year 2001 and with Linux since 5 years before at least. Honestly I didn’t realize that all this time was gone, but I saw the evolution of this particular open source software and I knew what it could get. To be an office suite that it doesn’t have nothing less than others most famous ones…indeed we can say the opposite.

Happy Birthday OpenOffice.org and thanks to everyone whose was working on the project.

During last weeks there was a lot of talk in Italy about Beppe Grillo, Italy’s most famous comedian, and italian politics, probably more talk will come in the future. But I wanted to point out to one of his article about Open Source titled Adopt a Penguin and written on the 26 September 2006. Yes, I known almost a year ago but I am living in Spain and I always get to know about Italian things in late. Beppe Grillo in his article highlights about the fact that Italian Government don’t look forward to the adoption of Open Source Software in the Public Administration even thought with all advantages that it will bring.

I have to say that here in Spain the situation is better, as an example the local government in the region of Extramadura has gone entirely open source, deciding to move its entire administration to Linux and Open Source Software and making a requirement to all its officials to use the ODF and PDF formats for all documents. Also it promotes the use in the schools of gnuLinex, a Spanish Linux distribution. Unfortunately the things do not go equally well in other regions, like here in Cantabria where the local politicians continue instead signing agreements with Microsoft without realizing of how much money they could save in software licences.

However I try to do my best with Open Source evangelization nearby, but unfortunately in Cantabria companies prefer to use proprietary software and, in the event of the small business, piracy gets very high percentages. In any case I think that the main problem here is the lack of knowledge rather than a clear will to get illegal software, therefore I take every opportunity to make people aware that there is one perfectly legal way of saving money in software.

At last I want to say that Linux is a good alternative also for home computing. I always heard that Linux is too difficult, that is good only for IT people, that it doesn’t have a nice Look and Feel, that there isn’t a good music player, that we cannot watch TV, etc… etc… well, all these arguments could be true until few years ago, but now there are no more excuses. The programs are there, the graphical interface is equally Nice and Easy to use as it is in Windows and if you want there is also the 3D version (created much time before Vista). The important thing is to choose the right Linux distribution, which in this case is Ubuntu Desktop Edition.

About Ubuntu Desktop I am actually preparing a series of articles, which I will publish weekly very soon, where I’ll get into the main topics and I will help you to make a complete migration from Windows to Linux. Stay tuned.

as you can see I did some changes, the most important one is the new domain name, anyway don’t worry for the old links because I wrote some URL rewriting rules so they get converted automatically.

I have also installed a MultiLingual plugin for WordPress that let me manage the blog in three different languages: English, Italian and Spanish. You can use the flags to change language.

Last thing is about comments, they are open now and you don’t need a registration to send one, but if I will get lot of spam probably get back as it was before.
