You might have noticed the word 'Walls' in the title. Actually, I was reading a technical article, China's Great Firewall spreads overseas. I noticed a new phrase "Great Firewall" for the first time. So, in world there are two great walls: The Great Wall and The Great Firewall. Both lie in China :).
Facebook wants to be the main river ?
A tributary is a stream or river which flows into a main stem (or parent) river. Facebook wants every site on the web to be a tributary. And it wants to be the main river using Open Graph API.
- Basically, the Open Graph API is a way for Facebook to allow other companies, sites, services, etc to interact with Facebook without having to create a dedicated Facebook Page.
- With the Open Graph API, Facebook wants to allow anyone to take their own site and essentially wrap it in a Facebook blanket. This doesn’t necessarily mean in a visual way, but rather that these sites which use the APIs will be able to replicate many of the core Facebook functionality on their own sites.
- So you can imagine that you might be able to create a Facebook-style Wall to include on your site, but able to update your statuses from your site, leave comments, like items, etc. Again, it’s like a Facebook Page, but it would be on your site. And you can only include elements you want, and leave out others.
Text 2.0 - Interesting
One of my friends has been keeping his messenger status : "Everything is 2.0" since last few months back. It is because he is working in Web2.0 and communication systems and he thinks that everything is changing. Text was in 1.0 but now it is approaching to 2.0. This fact supports him :). Watch the video below, it is really interesting one !
Facebook beats Google
Here is an interesting news copied from consumerist.com:
It's official -- playing Farmville and tagging friends in photos (and consequently untagging embarrassing photos of yourself from your friends' photos) has become more popular than actually trying to find things on the internet, as a new report shows Facebook edged out Google as the most-visited site on the internet last week.
According to Hitwise, Facebook accounted for 7.07% of all web traffic for the week ending March 13. That barely edges out Google's 7.03%.
This is huge news for Facebook, who only a year ago accounted for around 2% of U.S. web traffic.
XML Namespace: Attributes are a little different
An attribute can appear in a different namespace than the element that contains it. For example,
<movie:title xml:lang="fr"> has an attribute that is not from the movie namespace. If an attribute name has a prefix, its name is in the namespace indicated by the prefix. However, if an attribute name has no prefix, it has no namespace. This is true even when the default namespace has been assigned. The W3C Namespaces in XML Recommendation makes that point with this example:<x xmlns="http://www.w3.org" xmlns:n1="http://www.w3.org"> |
The elements are affected by the declaration of a URI for the default namespace. That is, both
x and good are associated with the URI "http://www.w3.org" because it's the default namespace. The attribute n1:a is also associated with that namespace, due to its use of the n1 prefix, which is associated with the same URI. There is no conflict that the a attribute is being declared twice, because while n1:a is in the http://www.w3.org namespace, the unprefixed a is not; the latter is not in any namespace.
Dependency Trees
A dependency tree is a graphical representation of a sentence parsed using a dependency grammar. The nodes in the tree correspond to words in the sentence being parsed (and sometimes to special synthesized nodes). The arcs correspond to dependency relations between a "head" word, at the upper end of an arc, and the dependent words at the lower ends of the arcs connected to the head word. The grammatical relations between head and dependent words are such things as subject, object, modifier, etc.
TPTP - A Java Profiling Tool
In software engineering, program profiling, software profiling or simply profiling, a form of dynamic program analysis (as opposed to static code analysis), is the investigation of a program's behavior using information gathered as the program executes. The usual purpose of this analysis is to determine which sections of a program to optimize - to increase its overall speed, decrease its memory requirement or sometimes both.
The set of profiling tools provides software developers or testers with the ability to analyze the performance of a Java program or to gain a comprehensive understanding of the overall performance of an application. Eclipse Test and Performance Tools Platform (TPTP) is such a tool used for profiling. A good tutorial is here: Tutorial.
