THE FUTURE of SCREENS from James Stanton a Little Bit About Me
THE FUTURE OF SCREENS From james stanton A little bit about me. Hi I am James (Mckenzie) Stanton Thinker / Designer / Engineer / Director / Executive / Artist / Human / Practitioner / Gardner / Builder / and much more... Born in Essex, United Kingdom and survived a few hair raising moments and learnt digital from the ground up. Ok enough of the pleasantries I have been working in the design field since 1999 from the Falmouth School of Art and onwards to the RCA, and many companies. Ok. less about me and more about what I have seen… Today we are going to cover - SCREENS CONCEPTS - DIGITAL TRANSFORMATION - WHY ASSETS LIBRARIES - CODE LIBRARIES - COST EFFECTIVE SOLUTION FOR IMPLEMENTATION I know, I know, I know. That's all good and well, but what does this all mean to a company like mine? We are about to see a massive change in consumer behavior so let's get ready. DIGITAL TRANSFORMATION AS A USP Getting this correct will change your company forever. DIGITAL TRANSFORMATION USP-01 Digital transformation (DT) – the use of technology to radically improve performance or reach of enterprises – is becoming a hot topic for companies across the globe. VERY DIGITAL CHANGING NOT VERY DIGITAL DIGITAL TRANSFORMATION USP-02 Companies face common pressures from customers, employees and competitors to begin or speed up their digital transformation. However they are transforming at different paces with different results.

“Web Development Using Python” 01 April 2021
A Report on the Webinar “Web development using Python” 01 April 2021 Organized by ‘Anacron’, Students association of the Department of Computer Science and Engineering, Akshaya College of Engineering and Technology A webinar, “Web development using Python” was organized by the students’ association, ‘Anacron’ of the department of Computer Science and Engineering, on 1-4-21. A brief report of the same is given below. WELCOME ADDRESS: Welcome address was given by Dr. N. Rajkumar, HOD/CSE, ACET. INTRODUCTION OF CHIEF GUEST Ms. J. Rajichellam completed her UG degree B.E CSE in Madurai Institute of Engineering and Technology. She is having certificates of proficiency in C, C++, HTML5, CSS, Javascript, Jquery, etc.,. She is having more than 6 years of industrial experience and currently working as Technical trainer in Elysium Academy. CHIEF GUEST PRESENTATION: Ms. J. Rajichellam started her presentation with a brief note about the future for Web development using python and then explained about the career opportunities in Python. She also explained as to why students should be well versed in python. She also urged the students to have a goal for their career and for that they should envisage a plan. She opined that without a plan they can’t achieve success. She said, Web development is an umbrella term for conceptualizing, creating, deploying and operating web applications and application programming interfaces for the web. She basically gave explanation for three topics. 1. Why is web development important? The web has grown a mindboggling amount in the number of sites, users and implementation capabilities since the first website went live in 1989. -

Cross-Platform Mobile Application for the Cothority
Cross-Platform Mobile Application for the Cothority Vincent Petri & Cedric Maire School of Computer and Communication Sciences Decentralized and Distributed Systems Lab Semester Project January 2018 Responsible Supervisor Prof. Bryan Ford Linus Gasser EPFL / DeDiS EPFL / DeDiS 2 Acknowledgements We would like to express our special thanks to Linus Gasser who gave us the opportunity to do this very interesting project related to the collec- tive authority (Cothority) framework developed by the DeDiS laboratory at EPFL. We would like to thank him for the valuable help he gave us whenever we needed and for the knowledge he provided to us throughout the semester. Secondly, we would also like to thank our parents and friends who helped us through the hard times of finalising the project within the limited time frame. 3 1 Abstract The Cothority2 framework has been developed and maintained by the DeDiS laboratory at EPFL. This project provides a framework for develop- ing, analysing, and deploying decentralised and distributed cryptographic protocols. A set of servers that runs these protocols and communicates among each other is referred to as a collective authority, or cothority, and the individual servers are called cothority servers or conodes. A cothority that executes decentralised protocols could be used for collective signing, threshold signing, or the generation of public-randomness, to name only a few options. The highest level of abstraction can be created by protocols like the collective signature (CoSi) protocol, the random numbers (Rand- Hound) protocol, or the communication (Messaging) protocol used by the conodes to exchange data. Then come the services, which rely on these pro- tocols.
