Linux Day is an Italian manifestation that promotes Linux and FOSS.
During this day different organizations (mostly Linux User Groups) arrange events with speeches, installation parties and more.

Since lot of people requested it, I gave a speech about KDE 4 during the Linux day organized by my LUG (BGLug).

The presentation covers the main changes and features introduced by KDE 4.
I took inspiration from Troy’s “Road to KDE 4″ articles (I like them really much).

People liked the speech and, most important of all, showed great interest for KDE 4.

You can download the presentation using the link at the bottom of the page. But beware: slides are in Italian.

You can also find some photos of the event here (thanks to Jimmy).

KDE4: what’s new

This speech illustrates:

• what’s desktop searching
• what’re the benefits of desktop searching technology
• what’re the programs availables under linux
• overview of Beagle
• overview of Strigi

I’ve uploaded the slides, you can find them in the paper category.

Slides are shorts since has been made for a “wiki-night”

KDE4 preview

Strigi desktop integration: how to access Strigi features.

Strigi, the fastest and smallest desktop search engine, provides fast searches and good metadata extraction capabilities. It will be used by the next KDE, but it can be easily integrated in other programs.

Long abstract:

Modern humans are using more and more data every day. Keeping data organized is becoming insufficient, so finding and filtering documents have become key tasks in modern operating systems. The traditional unix tools find, grep and locate do no longer suffice for a number of reasons: The amounts of data have grown more than data access speeds, many document formats are too complex to handle by simple tools and relations between different types of data are becoming more important for a convenient user experience. Strigi introduces a new way of looking at metadata and file formats that enables the creation of very efficient tools for improving the way users handle their data. It does so by using simple C++ code with very few dependencies.

Strigi’s features can be easily integrated by other programs using two different interfaces: socket and DBus. The last one can be considered the best choice since there are lot of DBus bindings that make possible to interact with Strigi using different programming languages. DBus inter-process communication system will be used by KDE4 and is actually used by Gnome. Moreover, DBus bindings exists for lot of programming languages. Thanks to this Strigi can be easily integrated in different window manager and inside programs written in languages different from C++.

KDE developers can also take advantage from Strigi’s JStreams: a set of classes for fast access to archive files. In fact Strigi defines a dedicated KIO Slave for JStreams, this can be easily used by other programs, making archives access faster.

This presentation will show how the current Strigi clients interact with the daemon, how to communicate with Strigi and, most important of all, how other projects can benefit too accessing Strigi.

Linux and modern console

This speech is about:

• crypted email with gnupg
• crypted file system avaible under linux, an overview and a comparison of loop-AES , cryptoloop, dm-crypt, bestcrypt
• creation of a full crypted file-system, root included. The most interesting feature is system’s boot sequence, which uses a usb token for authenticating users
