Now Google Chrome more faster on Android.

New TLS cipher suite in Chrome that operates three times faster than AES-GCM on devices that don't have AES hardware acceleration, including most Android phones, wearable devices such as Google Glass and older computers.

This improves user experience, reducing latency and saving battery life by cutting down the amount of time spent encrypting and decrypting data.

The benefits of this new cipher suite include:

Better security:-
ChaCha20 is immune to padding-oracle attacks, such as the Lucky13, which affect CBC mode as used in TLS. By design, ChaCha20 is also immune to timing attacks. Check out a detailed description of TLS ciphersuites weaknesses in our earlier post.

Better performance:-
ChaCha20 and Poly1305 are very fast on mobile and wearable devices, as their designs are able to leverage common CPU instructions, including ARM vector instructions. Poly1305 also saves network bandwidth, since its output is only 16 bytes compared to HMAC-SHA1, which is 20 bytes. This represents a 16% reduction of the TLS network overhead incurred when using older ciphersuites such as RC4-SHA or AES-SHA.

The expected acceleration compared to AES-GCM for various platforms is summarized in the chart below.

Part 1: Introduction to Bigdata

Image
Data! Big data is a generic term given to datasets that are so large or complicated that they are difficult to store, manipulate and analyze. We live in the market of data age. It’s very difficult to measure the total size of data stored electronically, but an IDC estimate put the size of the “digital universe” at 4.4 zettabytes in  2013 and is forecasting a tenfold growth by 2020 to 44 zettabytes. BigData is nothing but a problem in the current market because this particular data there is two problems, First one is the Storage and another is Processing. Like we are using social media app (Whatsapp, Facebook etc) or E-com apps,  they were generating certain Logs behind the application, why these Logs are important?  based on this Logs they can derive your browsing pattern, and based on this pattern they generate outcomes like which product is highest sold in the current month or which product is not sold in particular region etc.  and they can filter out this type

SoundCloud - A Twitter Product....Hows sounds it...

As per report from recode, Twitter is mulling plans to buy the German-based music-sharing service SoundCloud to fuel growth at the social network. The company is considering a deal to acquire SoundCloud, the music and audio-sharing company, according to people familiar with both companies. Berlin-based SoundCloud is a free service that lets users upload and share audio files around the Web; it likes to describe itself as the “YouTube for audio.” In October 2013, the company announced that it had 250 million users. arlier this year, SoundCloud announced a $60 million funding round that valued the company at $700 million. Last fall, as Twitter was preparing to go public, it acquired mobile ad company MoPub in a deal that valued that company above $300 million. A deal would also be Twitter’s second attempt to take advantage of the fact that some of its users talk about music and share links to songs they like. Last year, Twitter launched a stand-alone Twitter Music app, bu
