Firefox AppDay @ JNU Jaipur

Hello Folks….!!!

An another day came when we came back to spread the word of Mozilla with new comers and awesome people.

Event had been started at 10:00 AM by our Rep Mr. Ram Dayal. He told about the Mozilla and event.


After this session the next session had taken by Mr. Osho Parth, He told them about the open source and what opportunities in open source and also about the Cracking tips, this was an awesome session for students. They learned lot of new things during this session.




After this awesome session next session taken by me (Meghraj Suthar), in which i told them what is the Mozilla Community and what are the products of Mozilla and How a beginner can start contribution in Mozilla i.e. the ways of contribution.




After this session the next session started with the App Development by Mr. Tushar Arora, he told them what is Web App, and how to develop Web App.

After Tushar’s session we had break and after the one hour’s break we came back to App Development Hackathon, in which Mr. Ram taught them how to develop an App for FirefoxOS. He gave a live demo of App Development. In this session many students has made app for FirefoxOS.




After the Hackathon, Mr. Lavish Aggarwal, Mr. Adit Bharadwaj and Mr. Ashish Seervi told them about the Webmaker project and about its tools. Like- PopCorn, Xray-Goggles, and Thimble.

Thank You so much, We will be come back soon! Have passions!

Mozilla’s mozjpeg Project

JPEG has been in use since around 1992. It’s the most popular lossy compressed image format on the Web, and has been for a long time. Nearly every photograph on the Web is served up as a JPEG. It’s the only lossy compressed image format which has achieved nearly universal compatibility, not just with Web browsers but all software that can display images.

The number of photos displayed by the average Web site has grown over the years, as has the size of those photos. HTML, JS, and CSS files are relatively small in comparison, which means photos can easily make up the bulk of the network traffic for a page load. Reducing the size of these files is an obvious goal for optimization.

Production JPEG encoders have largely been stagnant in terms of compression efficiency, so replacing JPEG with something better has been a frequent topic of discussion. The major downside to moving away from JPEG is that it would require going through a multi-year period of relatively poor compatibility with the world’s deployed software. Mozilla doesn’t doubt that algorithmic improvements will make this worthwhile at some point, possibly soon. Even after a transition begins in earnest though, JPEG will continue to be used widely.

Given this situation, Mozilla wondered if JPEG encoders have really reached their full compression potential after 20+ years. Mozilla talked to a number of engineers, and concluded that the answer is “no,” even within the constraints of strong compatibility requirements. With feedback on promising avenues for exploration in hand, Mozilla started the ‘mozjpeg’ project.
