What Is Crypto - Currency?

Riddhi Gala (Xth STD, Abhinav Vidyalay) What Is Crypto-currency ? A cryptocurrency is a digital or virtual currency that is protected by encryption (plain text converted into unreadable text), making fraud and double-spending almost impossible. Many cryptocurrencies use blockchain technology to create distributed networks. This means that all your money is in different places and no one can trace it. Terrorists and criminals benefit from the possibility to keep crypto-currency without revealing their actual identities. People can also misuse it to store illegal money. Cryptocurrencies are online payment systems that are based on virtual "tokens" that are represented by records on the system's internal database. Various encryption methods that are converting a particular piece of information in a secret code to hide the meaning of information and cryptographic approaches public-private key pairs (it is for receiving crypto-currencies which are linked to a private key ), an

WHY I LIKE BOOKS WRITTEN BY SUDHA MURTY?

       - Gargi R Sawant (Std X, Abhinav Vidyalay) Sudha Murty, a famous writer of novels, short stories and travelogues, is a prolific writer who writes in English and Kannada. She has written many best-sellers for children. Born in Shiggaon in North Karnataka, she became an engineer and later taught in an engineering college. She is an MTech in Computer Science and the co-founder of Infosys, India’s thriving tech company. She has won many awards like the Padma Shree, the RK Narayan award for Literature and so on. I got to know this information when I started reading her books. I was in 5th grade when my mother brought me a book written by Sudha Murty named, 'GRANDMA'S BAGS OF STORIES' . When I read this book, I was totally fascinated and amazed by the stories, the storyline and also the way it was written. The simplicity in the language captivated me. In  the beginning of the book,  ajji-( grandma in marathi) is eagerly waiting for her grandchildren to arrive for th

Temples of Kerala

Archana Nair, Std X, Abhinav Vidyalay      I would like to tell you about my trip to Kerala. Kerala is located in southwestern end of the Indian Sub-continent. It is famous for its abundance in production of Tea & Rice. But let me tell you, it is also famous for its temples. I visited some temples in Kerala with my parents and grandparents.    First Temple we visited was Kottarakkara Shri Maha Ganapathy Temple, shortly called Kottarakara Temple. The deities of this temple are Lord Shiva, Goddesses Parvathy, Lord Ganesh, Lord Murugan, Lord Ayyapa and Nagaraja. All deities except Goddesses Parvathy and Lord Ganesh are kept facing towards the East, as in that temple main Gods and Goddesses face to east. Not only the name of the temple is Kottarakkara Ganapathy but also, the main importance is given to Parents God Shiva and Goddess Parvathy, the main offering of this temple is Unniyappam - a sweet round fritter mainly made up of banana, rice flour and jaggery. The main festival is

Jumpstarting the School Magazine

     Abhinav is now in it's 37th year of existence and we have so many stories to share. There have been so many wonderful people who became a part of the Abhinav family in all these years. There have been so many wonderful experiences that we have all had. Somehow I wasn't able to document these neatly enough.       I had attempted to begin this work 12 years ago with the Silver Jubilee of Abhinav. It, however, remained a one-time affair. Facebook posts and my randomly updated blogs could never do justice to the vast memories I have, or the wealth of stories that many would like to share. So here is another start. And this time we are here to stay. What's Different?      We began as a state board school and about 10 years ago, we changed to ICSE. This has given me some flexibility in arranging the curriculum. Socially Useful Productive Work is at the heart of the Gandhian philosophy of education as also the central principle of Abhinav's founder and my mother - Mrs. Ma

More Projects for X CA

Here are your projects X CA (2015-16). Each project must be  User-friendly (proper prompts and announcements to the user and good error-handling) Reader-friendly (documentation in code about what each class, method, data member is for or does) Generic (should apply to as many cases within the problem as possible, in other words assume the least) Object-Oriented (instead of making one long class, make many classes to properly hide data and keep things simple) It must be compiled as an app (albeit CUI-based) to run on any windows system. Different compiles may be needed for 32-bit and 64-bit systems.  You can team up in numbers up to 3 for each project, singles are also allowed. You get a week from this announcement to submit the source code and its compiled object code in a zip file (which includes any special libraries you may have created / used) as an email to me.  Projects for X CA 1.        Phone Book:   Make a database which accepts user defined number of records where each record

Adventure Sports - A culmination of the Sports Meet

Hello Dear Students & Parents!!! Last three weeks have been very busy, beginning with the Abhinav Stars and running into the camp and the sports meet. The last activity for the year (only National Science Day scheduled in Feb if the exam timetables permit) is coming to a close. We have been holding the  adventure sports each year for the last 25 years , with the last 15 years being done with professional help. Each student who has passed out of this school from std X or XII has (at least twice) did the variety of activities. The purpose of these events is simply -  Make one extremely confident .  Fear pulls you back from many things in life and the greatest fear is to hurt yourself or die. These activities make you realize that with a little science and technique one can achieve the impossible. Every one must do this at least once in their lifetime. We even encourage each of our teachers to do it. In fact even 50+ teachers have tried it for the first time in their lives at Abhinav.

Expression Calculator in Java

Std X CA students: Here is another assignment to be finished before Thursday 24th Apr, 2014, 8 am. Reverse engineer the application I have posted at the FB group - Expression Caculator . i.e. 1. download the file and save in the root of c-drive 2. run it in command prompt using "java -jar c:\exprcalc.jar" 3. enter various expressions to compute like 2 + 3 = (then enter) 4. once you type '=' and a white space and enter, it displays the result. 5. You can take a long expression like 7.5562 / 7.889 + 5 - 12.67 = (then enter) 6. You can type another expression after the result for the previous is shown. 7. It also handles errors well. Figure out the code and paste your answers here as a comment. Hint: It uses a blank for loop ... i.e. for (;;) { here goes the code }to repeat taking many numbers one after the other.

This code opens / creates / reads and writes / appends to text files as specified by the user.
