Raspberry Pi, a credit card sized microcomputer has unimaginable applications. This can be exploited according to the needs of an individual. This paper deals with the household computerization system installed using Raspberry Pi. The system is developed with the help of Twitter, an online social network which is used to send direct-messages to the raspberry pi which enacts a task accordingly by perusing the messages. The algorithm for the system is developed in python which is the conventional programming language that comes along with raspberry pi. The system is proved to be efficient and LED's were used to analyze the performance of the system and results affirm this conclusion.

Steganography is a tool which helps in hiding information that plays a crucial role in many ways and in many lives. With the advent of the Internet, information exchange is possible in many languages other than English. This technology eventually carries with it a disadvantage which is the loss of security and privacy of information. Steganography an insipid medium, is one such way to ensure privacy. Steganography plays a vital role in securing the secret data. In this paper, a different approach is chosen for encoding Devanagari (Hindi) Text in the cover image. This approach of hiding Devanagari (Hindi) and English Text in an alternate manner is very efficient and simple to use. This paper describes a duplet algorithm, one for encoding and another for decoding. The image parameters are calculated by this proposed methodology, which proves that this process is more efficient and innovative.
