So, what happened… in the last months I gave some talks about Ubuntu and Free Software, and I thought a lot about presentations, about the tools we use and how they can be improved.

I’m not happy with any of the opensource slide tool I used so far. The main argument is that they all *pretend* to have a linear flow of the conversation, while my speeches are almost never linear: I like to underline some concept announced before, or announce some other things I’ll speak about a few minutes later.

Think about that: almost always we follow an index, how many times every of us have to cut and paste it in some other position of the presentation, in order to start the next argument? Well, don’t know about *you*, but *I* do, and a lot of times.

Moreover, repeating things (with care, of course ) helps the comprehension of the listeners, and repeated concepts will be better memorized.

Also putting things in a pattern that resemble the reality helps understand and keep in memory what you said. Probably, if you’re talking about the GNOME stack you don’t absolutely want to just list the subsystems included, but you’d like to have something like a graphics and you’d like to focalize on each argument at a time.

That said: the only thing that fullfifth my wishes is prezi, but unfortunately that’s a closed/flash-based tool. Prezi is IMHO supercool, fast, and simple enough to create a presentation in few minutes (with a clear idea of what you want ).

So, I and a bunch of other Andreas  took the decision to wrote something that will be opensource, cool and easy to use. Well, it’s far to be complete and to be…aehm… “visually pleasant”, but it’s still growing.

The project is here, and I don’t hide that we need developers.

The status of the project is far from complete: but you can currently take an .svg built by Inkscape or any vectorial editor, use A4 to set a path in the presentation (like the prezi-style), and use A4 as a player for that presentation. We are developing a simple editor (we don’t want to re-implement another SVG graphics editor at all), and this is in progress.

Another thing we are currently evaluating is which framework use:  so, we have the default player written in gtk+librsvg+cairo, and a test branch written with the Qt Framework that use also an OpenGL renderer.

Probably, a graphical demonstrations is better than thousands of words, and (I hope that) will follow soon

But at that time, you can try it out with the daily builds (not actually daily, we trigger them by hands )

Just install the package along with its dependencies, and try out one of the test images inside /usr/share/a4/tests/images.

We hope you enjoy it !

Anche quest’anno si presenta bene: ospiti, eventi “sociali”, e talk per “vecchi e nuovi” py-sviluppatori…

Forse è tardi per dirvi di iscrivervi, ma se avete la possibilità ve lo consiglio di tutto cuore… Ubuntu (e Canonical in particolare) sta puntando sempre di piu’ su python per lo sviluppo di applicazioni, perfino in ambito desktop; se quindi vi interessa il nostro amato pitone, il Pycon è un posto chi vuole cominciare a imparare qualcosina, ma anche se siete esperti di programmazione potete scoprire cose sempre nuove  ( e se siete interessati a lavorare con python, c’è anche una sessione di recruiting delle aziende che hanno sponsorizzato l’evento).

Sarà inoltre un’ottima occasione per incontrare di persona alcuni membri della comunità di Ubuntu-it, alcuni maintainer Debian e far due chiacchiere insieme.

See ya there!!

For a really quick look, have a read on his conclusions.

Is it perhaps a well-known argument? Well, maybe I’m wrong, but don’t seems so, cause I actually found  a lot of code that use super() without (*args,**kw)  and such: going fix it.

La conferenza si terrà nella Facoltà di Ingegneria a Bologna, durerà tutta la giornata (a partire dalle 10.00 di mattina), e prevedere quattro talk, ve li elenco in breve:

• Presentazione del Linguaggio Python, caratteristiche e peculiarità – Enrico Franchi
• Test Driven Development con Python – Roberto Bettazzoni
• GTK, Glade, Python: dalla teoria alle GUI in tempo record – Pietro Battiston
• Django – Un web framework che rende facile sviluppare applicazioni web in modo rapido e con poco codice. Provare per credere. - Simone Dalla

Ti chiedere solo di aggiungere che è organizzato dall’associazione Terzo
Millennio con il contributo dell’Alma Mater Studiorum.

In ogni caso la giornata si prospetta interessante, in più è decisamente parecchio tempo che non si organizzavano eventi sull’Open Source a Ingegneria, quindi sono personalmente in trepidante attesa dei riscrontri,  e spero che il trend di “eventi nel bolognese” riprenda un po’ di vita.

Vi allego anche la locandina dell’evento.

update: specifico che il tutto è organizzato dall’associazione Terzo Millennio con il contributo dell’Alma Mater Studiorum.
