Difference between http & https

Image
FIRST, MANY PEOPLE ARE UNAWARE OF: **The main difference between http:// and https:// < HTTPS:/// > is. It's all about keeping you secure** HTTP stands for HyperText Transport Protocol, which is just a fancy way of saying it's a protocol (a language, in a manner of speaking) for information to be passed back and forth between web servers and clients. The important thing is the letter S which makes the difference between HTTP and HTTPS. The S (big surprise) stands for "Secure". If you visit a website or webpage, and look at the address in the web browser, it will likely begin with the following: http:// . This means that the website is talking to your browser using the regular 'unsecure' language. In other words, it is possible for someone to "eavesdrop" on your computer's conversation with the website. If you fill out a form on the website, someone might see the information you send to that site. This

e-skin

Researchers from Japan have developed a rubber that is able to conduct electricity well, paving the way for robots with stretchable "e-skin" that can feel heat and pressure like humans. The material overcomes the problems faced by metals -- which are conductive but do not stretch – which is the first in the world to overcome the problem and rubber, which hardly transmits electricity, according to the team at the University of Tokyo . The new technology is flexible like ordinary rubber but boasts conductivity some 570 times as high as commercially available rubbers filled with carbon particles. If used as wiring, the material can make elastic integrated circuits (ICs), which can be stretched to up to 1.7 times their original size. One application of the material would be artificial skin on robots as robots enter our everyday life; they need to have sensors everywhere on their bodies like humans. Imagine they bump into babies. Robots need to feel temperatures, heat a

Mac Vs. PC: Who's the More Considerate BitTorrent Software Thief?

TorrentFreak checked some seed and leech numbers of Mac, Windows, and Linux software to see who's got the nicer ratio. The results aren't without issues, but do suggest that Windows users/thieves are more polite. First, the caveat, and it's definitely a biggie. These numbers don't necessarily point to specifically Mac, Windows, or Linux users: Windows users may download Linux software, Mac users may download Windows software, and so forth. So this is not any kind of ironclad test. But it is a fair assumption that there is a strong correlation between platform and software downloaded, and these numbers are different enough to at least suggest that Windows users do indeed share more than either Mac or Linux users. The Pirate Bay , the web's largest tracker, was the source used for these numbers, and showed clearly that Windows software share ratio is more than twice that of Mac or Linux, at 2.55. Mac software clocked in at 1.19 and Linux at 1.39. This information
