Why did Leonardo da Vinci painted two Virgins of the Rocks?

July 29th, 2011 by Tsegaye View Comments »

which one do you like more? why? what are the differences?

It’s in the news that the Louvre (left painting) and the London’s National Gallery of Art (right painting) are going to reunite them for sometime for display. http://www.huffingtonpost.com/2011/07/27/two-versions-of-leonardos_n_911275.html

Two Versions of Leonardo Da Vinci's Virgin of the Rocks

This is a historic agreement between the two prestigious galleries. It’s also an epic time for Leonardo critics to see the two paintings side by side. We might get a better glimpse and meaning of the difference between these masterpieces done by the great Leonardo.

An excerpt and analysis from Leonardo’s notebooks on rocks and landscapes:

The colours of the shadows in mountains at a great distance take a most lovely blue, much purer than their illuminated portions. And from this it follows that when the rock of a mountain is reddish the illuminated portions are violet (?) and the more they are lighted the more they display their proper colour.

Probably, he was talking about what he applied on the painting on the right?

May 6th, 2011 by Tsegaye View Comments »

Have you ever wanted to find out who is behind the design, development of a website and wanted to find out who contributed what or even who funded the website? One initiative is pushing website owners to make their site ‘human’. In most cases, websites have robots.txt file in the root directory of the website that traverse the web and contains machine related information concerning the website and search engines use them to index pages.

According to humanstxt.org, the purpose is to know the people behind a website. It’s a TXT file that contains information about the different people who have contributed to building the website.

It’s a voluntary participation and easy to enable this txt file on a website.

Free Open Graph Manual

April 6th, 2011 by Tsegaye View Comments »

Facebook’s huge experience in making use of the existing open graph standards to enhance sharing of data over the web is really cool for Google to look into as it tries to climb up in the social space. Recently, with the introduction of +1, it makes it easier for Google to penetrate this. Although there is going to be a lot of work involved in integrating websites to be part of the social graph, I think it is a big start and I am excited to see how Google can come up with ways to do it.

+1

Google was late to understand the idea of relevant searches didn’t mean nothing unless they are socially interconnected through relationships. It later incorporated information from Flickr, Twitter and other sites so that users have a more relevant search result. Status update and sharing information among users was possible via Buzz.

That was just the beginning. Google was looking a better place to put related and relevant information in one place, a social platform. The Google profiles was meant to be a personal information platform. But Google started to infuse social form into it. The profiles section got revamped recently as part of their social strategy. The profiles page was not only to become a better user interface, but a future placeholder for personalized shared and related information and search results. Does the design looks familiar, something like Facebook? Yes, indeed.

Google +1With the introduction of +1, Google is taking relevancy to the next level, by enabling sharing recommendations to the world. Finally, all Google indexed information and data is getting a social form. Recommendations are now being part of the Google Profiles. Watch, the Google Profiles has already become a social platform in our eyes.

Do you think this going to be a Facebook killer? or at least matches Facebook in the long run? Add your thoughts in the comment section. What impact will it have in the whole social media arena?

I don’t have a +1 button yet for my blog :)

Shrinking Your Social Network to Connections That Matter

March 28th, 2011 by Tsegaye View Comments »

Mark Zuckerberg took our real experience to online presence. Facebook grabbed the world by the balls and the world embraced it. In the crescendo of an ever increasing members on Facebook and in the loudness of distributed human network over the platform, we can see a hint of a glitch that may eventually be repaired to help Facebook stay at it is or diminuendo is inevitable.

I am interested to share my status, photos, videos just like many million others on Facebook. I sometimes ask myself does it worth it? I took my time to go to the beach and I use extra minutes even hour to upload the photos and stay in touch on Facebook. Does it worth it? Letting hundreds of my friends know that ‘done this, done that’ experience adds to my happiness? No. I don’t understand the reason to get two lives (online and real) go in parallel. I am not against being social. But there should be a limit to us, a focus to some rather than telling the whole world about ones situation.

Most recently, we are found to be interested in a more closer network than before. GroupMe, Fastcompany, Fast Society, Beluga are on the forefront to achieve the goal of getting people be in touch with their close friends. A photo app that shares photos for friends at a wedding if they are close by 10 feet, is also an awesome app that how people are more interested to get connected to localized situation. Many of the new apps featured at the SXSW 2011 focused on group messaging. This shows how we are moving from a dispersed huge social network to a more confined and petite network.

Yes, we know about Vincenzo Perruggia. What about Picasso?

June 8th, 2010 by Tsegaye View Comments »

Italian employee at the Louvre in France, Vincenzo Perrugia stole the Mona Lisa in August of 1911 only to be caught in 1913 and the Mona Lisa was returned to the Louvre. This is one of the most famous art theft in 20th century. No one knows why Vincenzo actually did it. There were two theories why he stole the Mona Lisa.

One theory says Vincenzo was patriotic he wanted to bring Mona Lisa back to Italy because Leonardo Da Vinci was Italian so Mona Lisa belongs to Italy. Even now, Vincenzo is celebrated for what he did by Italians. Le’ts think this theory is true.

And now, about Picasso.

Pablo Picasso was suspected of the theft as his poet friend, Guillaume Apollinaire implicated him but later he was exonerated. But why did Pablo Picasso bought a sculpture stolen from the Louvre a couple of months before the theft of thMona Lisa ? TIME puts it: “Four years earlier, he had bought from Pieret (a con man working for Guillaume Apollinaire) two of the pilfered sculptures, Roman-era Iberian heads whose thick features and wide eyes he would introduce into the great painting he was then just about to embark upon, Les Demoiselles d’Avignon.”

Then I probably think that Picasso may have in his mind if he has the Mona Lisa painting, he might use some features of the painting for inspiration of his art work. If so, is it fair that taking the Mona Lisa or other masterpieces and use them for your satisfaction? what do you think? throw ideas in this note if you have more information.

This newspaper below is one of the papers in Italy which told the finding of Mona Lisa in 1913.

La Joconde est retrouvée… Mona Lisa is back! the reading starts. Joconde or La Gioconda is another name for Mona Lisa.

Facebook Community Pages – Connecting to Everything You Care About

May 21st, 2010 by Tsegaye View Comments »

Facebook guys experiment new tech, functionality and features in a bigger scale that can shock their users as we have noticed recently with privacy issues and other open graph protocol related debates. I love the way Google does, experimentation by invitation only and roll out comes later.

As we can see from recent Facebook developments, it feels to me that Facebook is planning to be a hub of the web in regard to providing the information we need without using systematic algorithm as Google does but through very relevant, semantically integrated connections, like people, photos, activities, etc. Most of the functionality try to mirror Google’s approach but in a different manner. Also I believe Community Pages is one of Facebook’s strategy to create a wiki like, but more official information providing platform, in the same way Google tried using knol http://knol.google.com/k.

As seen so far, Facebook guys are working on finding any possible connections you have with the world around you and make it dynamic and accessible. Facebook community pages are one of these connections, that connect you to everything you care about, everything you want to do, everything you love to hear about and be able to see others who have similar interests.

It’s not the right time to speak a lot on the benefits of Facebook’s Community page. Neither it’s simple to forecast that we will have a better version. We have seen a dozens of applications deactivated or removed indefinitely and replaced with new ones.

Facebook Powered Web

April 29th, 2010 by Tsegaye View Comments »

A new data model for the web is unfolding. It has been in the Facebook labs for some time. Participating sites are now integrating this model on their sites and rapidly building up relationships the so-called connections (e.g., friend relationships, shared content, and photo tags) and diving into the social graph, a representation of our relationships. This has a magnetic effect for the web at large. When a site’s visitor log into such participating sites, brings their connections/relationships to the site which will indirectly bring up the connections through content recommendations, friend’s activity, news feed, and status message notices. This shows how fast people are climbing to the same tree, the new Facebook data model and branch out and reach out to their networks of friends and connect with other Facebook objects such as photos, events, and fan pages.

Recently, it has also been rumored that Facebook is getting more popular than Google at least in the U.S. It’s partly because of online social connections are growing faster and widely spreading games such as farmville, partly Facebook plays on a more semantic, smarter web that creates a real online interaction with people. It seems that we are heading toward not Facebook but Facebook platform centered web, which means a lot of our important content we want to share, connections, and what matters us most hit Facebook than any other social site or simply any site in the future. Are you ready?

Facebook's Connections-based Web

Very soon, the Facebook platform is going to be the epicenter of the new web (in my opinion) should the new system is embraced with open hands by most constitutions and it will bring such an impact that never happened in the last two decades. Once the connections, relationships and objects are all related, established and intertwined, it is going be so easy to find the information you look for at your fingertips. You may not need to use keywords, rather you may trust the opinion of your friends/online relationships that you are connected with and care to pick up what you want, to choose out of many options. As Facebook’s Bret Taylor puts it in his blog, the underlying graph of connections just needs to be mapped in a way that makes it easy to use and interoperable.
