Mozilla, non-profit organization, well known for its Firefox web browser and Thunderbird mail client has recently moved to the mobile space with Firefox for Android browser for smartphones and tablets. However they intend to go even further by releasing a mobile operating systems named Boot to Gecko (B2G) competing directly with Android, iOS and Windows Phone. Mozilla mobile operating system will use web standards (like Tizen does) and the goal is to displace proprietary, single-vendor stacks for application development (e.g. Android, iOS, WP7).  The OS itself will relies on the Linux kernel and some open source libraries and the B2G applications will be written using HTML5/Javascript/CSS3 standard.

SPDY Aims to Make the Web Faster and Replace HTTP

SPDY (pronounce “SPeeDY”) is a new protocol designed by Google that aims at making the web faster and eventually replace HTTP. This new protocol is not a new scheme, so it would be transparent to the user and there would not be a new spdy:// prefix and we would still be using http://. It will always be secure and use tcp port 443 instead of 80 (because of transparent proxies messing up with packets). Most of Google products such as Chrome, Android Honeycomb (They can’t say if ICS is using SPDY…) devices and Google’s servers have already using SPDY protocol for some time, and Google reports some encouraging results. The tested 300 sites from the top 1000 Alexa sites and found an average 40% page load improvement. They also reported some labs tests: *PLT stands for “Page Load Times” in the chart above. Google is not the only company using […]
