Sociala nätverk läcker personlig data

Forskare vid AT&T Labs och Worcester Ploytechnic Institute har undersökt hur säker hanteringen av personlig data är mellan sociala nätverk och 3e part. Resultatet är, inte helt oväntat, inte så betryggande.

"When you or I create an account on an online social network, there's a unique identifier that's always associated with your account. That account number is being passed along to these third party aggregators. And along with the cookies these aggregators are already maintaining, they now can link that cookie to a social network identifier."

The study looked at twelve social networking sites: Bebo, Digg, Facebook, Friendster, Hi5, Imeem, LinkedIn, LiveJournal, MySpace, Orkut, Twitter, and Xanga.

"Not only do they know where I'm visiting, they know who I am," said Wills. "And that's disconcerting."
[...]
The report does not suggest that there's misuse of this information by third party aggregators and notes that contracts between social networking sites and third party aggregators may require aggregators not to use identifying information.

Value, cost and price of cloud computing

Often-times, the three words: value, cost and price, are considered somewhat interchangeable and sometimes that might be correct. However, let’s make a distinction for now and look at cloud computing.

Value is tied to the utility rendered from a product, service or technology.
Cost is tied to the consumption of resources (financial resources, man hours, energy or other) needed to perform or produce a product or service.
Price is the, by the market, agreed upon amount needed to acquire a product or service. The price determines who of the market participants that will capture the value rendered.

From fundamentals to market specifics

The order by which the three concepts were mentioned above was not random. When trying to determine the possible benefits of IT as a Service for the system of industries associated with IT, the analysis should start by determining the increased value it brings. Secondly, the cost implications needs to be considere. After looking at the big picture and establishing that the increased value outweighs the increased costs (if any), the next question is how the excess value is devided among the market participants.

Forget cloud - box computing is the future, Says Baidu CEO

The vastly admired Robin Li, presented the box computing concept at Stanford University today. Upon booting up a netbook och phone, the box is available instantly, before the OS or a browser and the functionality is similar to the frontpage of baidu.com. The box is the future of web for Baidu.

I have to admit that I don't fully understand the benefit. The concept is either very smart or quite stupid. And as for "before the OS or a browser": I have access to a browser within a second after opening a Macbook or starting a iPhone - today, pre-box computing.

The problem with Google Sidewiki

Sidewiki from Google has been getting a lot of attention today. However, I agree with Jeff Jarvis at Buzz Macine:

"I see danger.

Google is trying to take interactivity away from the source and centralize it. This isn’t like Disqus, which enables me to add comment functionality on my blog. It takes comments away from my blog and puts them on Google. That sets up Google in channel conflict vs me. It robs my site of much of its value (if the real conversation about WWGD? had occurred on Google instead of at Buzzmachine, how does that help me?). [...]

So this goes contrary to Google’s other services – search, advertising, embeddable content and functionality – that help advantage the edge. This is Google trying to be the center.

[...] Google is about supporting the internet – adding value to it more than extracting value from it (and from those who create the value… at the edge)." (emphasis added)

 

The success of Google has previously been to help others get better (webservices to improve with embeddables and analytics, content providers to reach out and businesses to connect with the right customers at the right time etc..) without putting itself on center stage. A difference of principle between Google and Yahoo/Bing in search is Google's ambition to get the user away from google.com as fast as possible (although Carol Bartz claim that Yahoo was never a search company...). The principle behind sidewiki is the complete opposite.

Nokia is becoming the Yahoo of the mobile world

Via GigaOm - Dopplr Commits Hara-kiri, Sells to Nokia

"At our Mobilize 09 conference, someone joked that Nokia was the Yahoo of the mobile world. I’m sure he meant that Nokia was bereft of direction and purpose. You can also extend that argument to Nokia’s acquisition strategy. The company has been buying up tiny companies, hoping to get a bit of web services magic. [...] I think that Dopplr, a London-based startup that marries location services with the social graph, is committing hara-kiri. The company is rumored to have been acquired by Nokia for between $15 million and $22 million."
