I was surfing the web, as usual and I wanted to take a look at Bing's source code because I was curious and wanted to know what they were using to make their image fade in. I was surprised by what could only be qualified by the following line : Holy wall of text! And it made me wonder if there is any advantage to obfuscate your (X)HTML...

In the same vein of an initial crack of the Blu-ray movie format, hackers just inspected the memory of a player to snoop out a key value. It seems like it's feasible to do the same thing with browser memory, and to look at values that th...

It opens neither a tab nor a window: the code for a Google Gadget here. If you know 'target="_blank"' from HTML, I am looking for a similar tool for Google Gadgets. More precisely, I cannot understand why the JavaScript piece does not work: window.open("http://www.google.com/"); ...
I have 1000 rows of data but need to only display 100 rows at a time.
