Project Natal – XboX 360

Oggi, leggendo una guida sulla “Search Engine Optimization” redatta da Google, ho scoperto il magico mondo del “nofollow”.

Ogni sito web ha la sua reputazione all’interno del motore di ricerca di Google, e questa reputazione dipende da molte variabili.  Una tra tutte è l’uso dei link.  Un link verso il nostro sito presente su un altro sito con reputazione maggiore del nostro influenza in parte la nostra reputazione aumentandola.

Questo ha dei vantaggi, ma anche degli svantaggi: per proteggere il nostro sito da spammer desiderosi di un pò della nostra reputazione, infatti, è possibile fare uso dei link “nofollow”.

Per fare ciò è sufficiente aggiungere l’attributo rel=”nofollow” al tag <a> dei link cui non vogliamo donare la nostra reputazione.  In questo modo, infatti, i crawler di Google, quei ricercatori adibiti all’analisi dei siti web e all’assegnazione della reputazione, eviteranno di seguire quei link e non attribuiranno loro nessun tipo di reputazione.

Es: <a href="www.libero.it" rel="nofollow">Libero</a>

In aggiunta, per completezza, esiste il tag

<meta name="robots" content="nofollow">

che, inserito in testa alla nostra pagina Web, dirà ai crawler che tutti i link presenti nella pagina non dovranno essere seguiti, quindi è come se mettessimo un rel=”nofollow” a tutti i link della pagina.

Spero di essere stato utile a qualcuno.  Se aveste consigli o critiche lasciate pure un commento.

E’ appena arrivata la ricarica promessa da parte di ZZUB per chi avesse aderito alla campagna Vodafone Casa Direct.

A breve ulteriori informazioni sulla campagna.

Da oggi mi attivo ufficialmente come ZZUBer (non sapete cos’è ZZUB? Date un’occhiata qui, quando ancora si chiamava BZZers) anche sul mio blog promuovendo nel mio piccolo e permettendo la condivisione del vostro punto di vista sui prodotti che avrò la possibilità di provare.

Oggi parliamo di “Io smetto così“, una campagna di sensibilizzazione sociale sulla pericolosità del fumo in collaborazione con la LILT (Lega Italiana per la Lotta ai Tumori).

I pericoli portati dal fumo sono ormai ben conosciuti da tutti: tutti ormai sappiamo che il fumo provoca il tumore ai polmoni (e non solo), su tutti i pacchetti c’è scritto “Il fumo uccide”, eppure molti fumano ancora oggi.

Chi per noia, chi per necessità, chi per…

Per tutte queste persone, e per chi sta provando a smettere o ha già smesso e non ci vuole rientrare (perchè ricordiamo che il fumo provoca anche dipendenza) è partita questa nuova campagna “Io smetto così” per aiutare queste persone.

Sul sito potete trovare materiale informativo, quiz divertenti e quant’altro.

Vi invito a farvi un giro e, perchè no, a fare un pò di informazione per voi e per gli altri.

Oggi ho scoperto questo servizio molto interessante: METEOSTONE.
Si tratta di un servizio Web in perfetto stile 2.0 in mashup con Google Maps.
Sfruttando il servizio tanto blasonato di Google Maps, infatti, è possibile aggiungere alla cartina il tempo meteorologico corrente in ogni località del globo.
In questo modo è possibile vedere il tempo che fa attualmente ovunque grazie a delle splendide iconcine e alla possibilità di aggiungere commenti e quant’altro.
Molto interessante, vi invito a provarlo e a dirmi la vostra opinione…

These were the presentations:

Roberto Acerbis, Aldo Bongio, Marco Brambilla, Stefano Ceri, Massimo Tisi and Emanuele Tosetti.
Developing eBusiness solutions with a Model Driven Approach
I already knew these guys and I already knew what they did! It is very surprising for me the increase in speed of work and decrease in work-hours due to the tools used in this case (WebRatio) which allow to mantain a very big architecture and Web Application with less time and work.

Emily Medina, Sunny Fugate and Marion Ceruti.
Next-Generation Tactical-Situation-Assessment (TSAT): Chat

Marco Brambilla, Jordi Cabot and Nathalie Moreno.

IWWOST

IWWOST workshop presented some papers:

I address to the link to know more of the presentations.

Then they have a sort of round table where everyone asks questions, shares ideas, presents issues: a very good example of sharing knowledge and synchronizing ideas.

Conference Social Dinner

But in the end of the day everyone was waiting for the Social Dinner at Villa Serbelloni in Bellagio
In the websites you can see many pictures of that very beautiful Hotel.
First of all we took a boat which took us to Bellagio from Como.
Then we could walk along the very beautiful and very small town.
At 8 o’clock we started our dinner with very good service (not Web Service luckily ) and very raffinated food and wine.

I’m waiting for your comments!

Today is the really first official day of the Conference.
After the Welcome Cocktail held on Villa Olmo on monday evening (anyone impressions? Comments here…) today Works are starting up with the Official Opening Ceremony of the conference performed by the Chair Professor Piero Fraternali.
After a short presentation of the city, the university of Politecnico di Milano, and the works that have to be done during the conference, he passed the token to mr. Adam Bosworth, Vice President of Engineering at Google inc.

This “guy” has been presented as one of the man who took part to the story of Internet and Computer Science, and he didn’t disappointed the audience.  His keynote was very dense and full of ideas about “The future of Web and Desktop applications”.  I personally found very attractive his way of speaking about it balancing technical things with psychological topics and so on…  In the end of his speaking he made a little presentation about Google Gears, the new technology implemented by Google in order to allow people and (only certain kind of) Web Application to work also without direct connection to the Internet, synchronizing all the data only when connection is active (similar to Blackberry I think…).

Then, during the day, there have been one Workshop, two Research Session (“Services” and “Metrics”) and two Events (“ALFA project” and “DISCoRSO project”) but I could take part only to the workshop, so I hope someone could add their impression on the others events here in the comments.

The workshop was about “MDWE: Model-Driven Web Engineering”.
It was held by Geert-Jan Houben and Nora Koch and it allowed people to show their papers and works to the audience inviting them to discussions and also collaboration I think…
The presented papers could be found here.

Patrick Freudenstein, Jan Buck, Martin Nussbaumer, Martin Gaedke
“Model-driven Construction of Workflow-based Web Applications with Domain-specific Languages”

Pau Giner, Victoria Torres, Vincente Pelechano
“Bridging the Gap between BPMN and WS-BPEL. M2M Transformations in Practice”

Andreas Kraus, Alexander Knapp, Nora Koch
“Model-driven Generation of Web Applications in UWE”
This was one of the first times I heard about UWE: it is more or less an extended UML to design Web Applications.
In the end I was very impressed by UWE, so “Good Luck guys!”.

Manuel Wimmer, Andrea Schauerhuber, Wieland Schwinger, Horst Kargl
“On the Integration of Web Modelling Languages”
Very beautiful presentation about the need to integrate the Web Modelling Languages. It was very interesting for me to hear about the many Web Modelling languages and how do they work but I can’t understand why there are so many (my answer is: for the same reason we have so many car manufacturers, fashion brands and so on…) and what are the differences between them. Is there a language better than the others?

Valeria De Castro, Juan Manuel Vara, Esperanza Marcos
“Model Transformation for Service-Oriented Web Applications Development”

Giovanni Toffetti Carughi
“Modeling data-intensive Rich Internet Applications with server push support”
I found this paper very interesting also because I knew many of the things that were presented. I found these RIA very interesting for the future, but I have the same doubts that Adam Bosworth raised during the morning: “Are these Web Applications suitable for every connection? for every device?”
I think that the future shoud be on the Web-Desktop Applications: perhaps today they are not suitable for everyine, but in the future…

Come vi avevo preannunciato, la Conferenza Internazionale per il Web Engineering è arrivata.
La Conferenza è Internazionale, quindi, purtroppo per i miei lettori italiani, gli articoli saranno scritti il più possibile in Inglese.

As I announced, ICWE 2007 is arrived.
This morning conference started with the tutorial on Web Services and a Workshop on Web quality, verification and validation.
Unfortunately I can’t participate to them so I start following ICWE from this afternoon.

– Update –

As a Student Volunteer I have to help during the sessions and now I’m helping at the MDWEnet meeting.
This workshop has a first meeting today and we will meet also tomorrow (tuesday) for the real MDWE Workshop.
Model-Driven Web Engineering meeting collects the ideas of many people involved in research about model-driven WE.

Presentation #1
Universidad de Alicante, Spain

Presentation #2
Politecnico di Milano, Italy
Evaluation techniques in WebML models.
Creation of metamodels using transformations in FPA metamodels to do some methric calculations.

Presentation #3
Technical University Vienna, Austria
Creation of a Map of projects with similar goals.
They created a method to translate from a Model to another Model and they think they will show a demo next meeting.

Presentation #4
Ludwig-Maximilians-Universität München, Germany
UWE – Uml for Web Engineer
Presentation about problems related to the information about this area: creation of a wiki, production of papers, stuff…

Presentation #5
University of Alicante, Spain
Alicante “Work On Progress”
-Evaluation on Quality and Effort in developing Web Applications.
It stands out a request of collaboration with Politecnico of Milano to compare the two methods of evaluation.

PS: I would like to underline that all what I write here is only my personal understanding and interpretation of what happened at ICWE, so take it as is.
If you want to add your opinions or correct some things please add a comment!
