Grammarly opened access to the SDK and launched a platform for developers
The company Grammarly, known for its online service for correcting texts in English, announced the launch of a beta version of the Grammarly for Developers platform.

Facebook has developed a new data compression technology for mobile applications
Facebook has developed Superpack asymmetric data compression technology. The technology uses compiler analysis and data compression to optimize information storage. According to company spokesman Sapan Bhatia, mobile applications continue to grow in size, which has a negative impact on the performance of gadgets. Compilers currently in use, such as Deflate and LZMA, are currently coping with data optimization, but they will soon lose their relevance. Superpack's operating principle is based on Kolmogorov's complexity theory , according to which the information content of a piece of data is determined by the size of the shortest program that can generate that data. Facebook said Superpack technology reduces the size of Android apps by an average of 20% compared to regular compression. Superpack is already used in Facebook, Instagram, WhatsApp and Messenger applications. Source: Facebook
