Sembra scritto pensando a http://weshowthemoney.com/italiaAMMINISTRATORI IN CONDOMINIO *
di Carlo Drago , Andrea Polo e Paolo Santella 06.12.2007Nel periodo 1998-2006 la grande maggioranza delle società quotate italiane è stata collegata in un'unica rete attraverso una piccola minoranza di amministratori. Un gruppo, questo, che mostra grande stabilità nel tempo e con componenti che spesso appartengono alle stesse famiglie. Assai alto il grado di connettività per le blue chips e in particolare per quasi tutte le principali società bancarie e finanziarie. Negli ultimi anni tende a ridursi il numero dei collegamenti, ma non delle società coinvolte, con una maggiore centralità di Mediobanca. E la concorrenza?

A review of TREEPIE:
[..]But now there's a new contender called TreePie [4]. Basically, TreePie represents disk usage like a pizza with the size of each slice representing the space taken by each top level folder. Clicking a folder "slice" will then display a similar "pizza" breakdown of the sub-folders and files in that folder. It sounds complicated when I describe it but it's simple and intuitive in use.
It's also highly effective. Add to that the fact that it's also portable, has an alternative Windows explorer view and is free open source software and you have an easy "top product in class" recommendation.
My only complaint is its rather slow scan time. Still, this is not the kind of program you will be using everyday so a short delay is quite tolerable

UnfluenceBlog: "Sister project
November 26th, 2007
Great minds think alike. Marco Borgna just contacted us to tell us about a nice Java/prefuse application he built to show networks of contributions to US governors races using NIMSP data. Check it out at http://weshowthemoney.com/
A nice feature is that it is shows data combined for multiple states, so you can get a picture of the activity of unions and PACs at the national level.
Are there any similar projects showing EU data?"
Unfluence is a great project of visualization !

UPDATE 9.28 25/11/2007: first version application online. send comments ( and report bug bug@weshowthemoney.com )! :D
My friend Daniele Galiffa from Mentegrafica.it has pointed me to the data coming from Follow The Money a nonpartisan organization dedicated to documentation and research on campaign finance at the state level.
I have used for now only data about Governors elected in 2006 and used they top 100 donors.
Images here and in my photo blog are the results of my first attempt to show the data using the prefuse visualization library
I will release the applet to produce the images when ready :D .
Italian follows :)
Qui potete vedere cosa si può fare in America con i soldi.
Qui potete vedere che cosa succede tra i soldi e la politica in America.
Qui potete vedere l'America.
Abbiamo ricavato i nostri dati da Follow The Money e li abbiamo resi visibili.
Si vede l'ambiguità di chi finanzia indistintamente Repubblicani e Democratici.

Some tip for mac-os users:
Confessions of an Undercover Geek » Where did all my hard drive space go?:
"Where did all my hard drive space go?
Lately it seems like my hard drive space had been getting less and less.
On Friday, I was watching the latest episode of DL.tv. They talked about different tools you could use to visualize where the space was being taken up on your hard drive. The mac tool they talked about was Disk Inventory X. It is awesome.
It shows a rectangle and splits the rectangle up with different colors and boxes to show the different files that are taking up space on your hard drive. The tool makes it easy to go and clean out old files that are taking up space. I was able to successfully clean out a bunch of space on my hard drive.
This tool just works for Mac OS X. If you are a Windows users, there is SequoiaView and TreePie."

comment on treepie:
and also some interesting comment in: http://sourceforge.net/forum/message.php?msg_id=3822519
I went looking for software to search for large files and found that most of the “good stuff” is commercial. However, a fella in Italy has written a clever open source program called Treepie. At first glance you will look at the output and think “What the hell does THAT mean?” but once you start running your mouse over the output you will see how he’s organized things and it makes a lot of sense.
It’s not the fastest or the slickest program in the world, but it’s free and it gets the job done. It helped me find a folder off my root directory where I had forgotten to delete a number of ummm *cough* DVD images *cough*. Data, of course.

visualcomplexity.com | Musicovery: "Musicovery, by Frederic Vavrille, is an interactive webRadio, or if you want, an hybrid of two of the most compelling music services on the Internet, MusicPlasma and Pandora. Frederic Vavrille, creator of the discovery engine MusicPlasma, has just materialized my wish. Being an enthusiast of both services, I had acknowledged that Pandora was missing a visual component in order to map all the relationships and influences between the artists, while on the other hand, MusicPlasma was lacking a key feature of a music engine, sound."

I'm working on some new idea on how to make a smarter local homepage.
Instead of using as homepage google.com or yahoo.com why don't using a configurable local page with some IFRAME inside pointing to google and yahoo but also showing my link.
Persistence is obiousvly the problem, but it can be fixed by using a site as a configurator and at the asking the user to download the modified page.

Something like treepie forMac :
GrandPerspective is a small utility application for Mac OS X that graphically shows the disk usage within a file system. It can help you to manage your disk, as you can easily spot which files and folders take up the most space. It uses a so called tree map for visualisation. Each file is shown as a rectangle with an area proportional to the file's size. Files in the same folder appear together, but their placement is otherwise arbitrary.

If anyone known some other software for Disk Usage Analysis or more generally for Disk Management please give me a feedback to borgna.marco a t gmail.com or post a comment here.
And also somebody has see this type of multilevel pie used in any others field? It's really used only to show folders size ?

Do you need something similar to TreePie for Linux ? Bored of DU ?
try Filelight
it' s the coolest approach to disk usage display: TRY it!
You can also try KDIRSTAT wich is more serious and with a lot of functions, but less informative. It use treemap display: lot of confunsing squre one inside other to display disk analysis.
For windows a lot of disk usage tools are available (most as shareware):
Space Searcher
FolderSizes - Disk Space Management Software

WOW! Nintendo ha finalmente svelato quale sarà il controller della nuova console "Revolution" [+] . Sembra uno stupido telecomando ma in realtà è in grado di "sentire" la distanza e la posizione dalla console. Potete già immaginare quanti nuovi tipi di gioco si possono fare!
Una nuovo passo nel tentativo della Nintendo di coinvolgere nuove fasce di età e di uscire dalla nicchia dei "core gamer"... insomma far giocare anche la fidanzata, il nonno e la mamma del giocatore tipico.
Shigeru Miyamoto a 20 anni esatti dalla creazione di SUPER MARIO BROS è l'attuale artefice dei questa svolta... che deciderà il futuro della Nintendo.
Non sono riuscito a trovare nulla riguardo al supporto di Java sul Nintendo Revolution : visto il target di utenza particolare credo che la possibilità di sviluppare applicazioni in Java da scaricare da Internet sarebbe molto utile.

Windows VISTA e OPENGL La Microsoft fa il solito giochetto del supporto "parziale" di Opengl:
Opengl su Windows Vista sarà gestito da un strato su DirectX ma se un applicazione Opengl sarà attivata il "desktop compositor" sarà disattivato degradando le prestazioni.
Questo significa che:
- OpenGL performance saranno ridotte in maniera significativa (50% ?)
- OpenGL on Windows sarà fissato definitivamente alla versione 1.4 di OpenGL
- non sarà possibile aggiungere estensioni ARB post 1.4
post su OPENGL.ORG che spiega il problema (in inglese)
Gli sviluppatori dovranno impazzire per far funzionare le cose su più macchine.
Che noia!
Chissà se TREEPIE funzionerà ancora!

SISTEMI PREVALENT
Un articolo interessante:
Prevalence: Transparent, Fault-Tolerant Object Persistence by Jim Paterson
ITA: sui sistemi di persistenza "prevalent" che permettono di gestire il "salvataggio" degli oggetti mantenendone l'integrità transazionale MA SENZA USARE UN DATABASE!Il framework più usato, per java, è Prevayler.
(tra l'altro come tradurreste prevalent? predominante? prevalente? mah!)
ENG: Want to persist your objects, with transactional integrity? You probably assume you're going to be using a database, but not so fast--for lighter uses, particularly for prototyping and testing, the idea of "prevalence" may make more sense. Jim Paterson introduces it by way of Prevayler, a popular prevalence framework.

I Generics sono l'equivalente dei template del C++ per JAVA. La prima volta che li ho visti ero un po' dubbioso... perchè aggiungere a Java le difficoltà del C++ ?
Perchè i Generics sono potenti e anche semplici!
Come farne a meno? :P
In sostanza si tratta di creare funzioni e classi generiche che utilizzano delle variabili o delle classi i cui TIPI che verrano definiti al primo uso (a compile time) .
In c++ i template sono POTENTI ma posso confondere e spaventare l'utente non smaliziato. In Java sono più semplici e appaiono piuttosto utilizzabili.
un po' di risorse....
Generics in J2SE 5.0 by Budi Kurniawan -- Generics are one of the most prominent language features in J2SE 5.0, but are you using them yet? Properly used, they allow greater flexibility, compile-time type safety, and fewer annoying and potentially unsafe casts. In this article, Budi Kurniawan shows how they work. (OnJava, molto ben fatto)

Sto meditando si fare un test di tutte le applicazioni con tanto di voto (TREEPIE ha già il massimo :P)
TreePie ha ricevuto il riconoscimento di Softpedia in quanto 100% FREE!
