EAV versus Row modeling
Following are main features/downsides EAV has over classic row modeling technique. A row-modeled table is homogeneous. I t will always carry same type of data in contrast to EAV modeled table where this cannot be an issue. The data type of the value column/s in a row-modeled table is pre-determined by the nature of the facts it records. In contrast, in an EAV table, the conceptual data type of a value in a particular row depends on the attribute in that row. A Row modeling technique data increase only in one direction i.e. from Upside-down whereas in EAV data model data increase in both directions i.e. from upside down as well as from left-right.

Google reCAPTCHA cracked
Despite denials from Google, a security researcher continues to assert that the Search King’s reCAPTCHA system for protecting Web sites from spammers can be successfully exploited by Internet junk mail panderers. Researcher Jonathan Wilkins published a paper recently that included an analysis of reCAPTCHA’s security. In automated attacks he conducted against the system, he reported he had an alarming success rate of 17.5 percent. CAPTCHA–which stands for Completely Automated Public Turing test to tell Computers and Humans Apart–is a method for foiling automated attacks by spammers on Web sites. Before a Net surfer can perform at a site a task, such as setting up an email account or adding comments to a blog posting, he or she is presented with the image of a word or phrase that has been distressed in some way. The warped image is intended to thwart scanners and optical recognition software programs used to automate the compromising of web sites by spammers. The idea is that humans

IPSC 2010
Roughly a thousand teams from all around the globe have already registered for IPSC 2010 , which takes place on Sunday, June 6. $3,000 in prize money (courtesy of Facebook, Inc.) is waiting for the best few of them. Participation is free and the contest is open to everybody. IPSC is what you could call a programming contest with a twist. Over the years, the problems always push the boundary and go beyond the usual stuff you see in a programming contest. For example, in past few years the contestants have had to understand how arithmetic in computers differs from that in mathematics, produce a sequence of cache requests that generates many page faults, solve a logic puzzle given as a Flash game, and recognize images to evaluate a rock-paper-scissors game.
The bug in the name of the C++ language.
From the internet, a popular quote goes like this: "Of course, while it is true that the ++ operator gives the C++ language its name, it also led to the first joke about the language. C++ haters point out that even the name of the language contains a bug: 'After all, it should really be called ... ++C, because we only want to use a language after it has been improved.' " We will now see why this joke is so absolutely hilarious. int main() { int x = 40; int y = ++x + 1; std::cout << x << '\n' << y; } Output: x = 41, y = 42. The pre-increment operator first increments the value of x (the ++) and then stores it in the variable. Hence, when the code is executed, x becomes 41 AFTER being assigned to y . The post-increment works the other way, the value is first stored in the lvalue before being assigned to the rvalue of the variable being incremented. int main() { int x = 40; int y = x++ + 1; std::cout <&l
