Sharing a small page I cooked up to help people explore transformations - both the linear and the non-linear kind by drawing pictures and modifying them using transformations. This hack is in the spirit of the theme of this year’s Infinity festival at Pramati - where we have “Engaging the senses” as a theme. So, engage your senses to grasp the math of transformations.

Diffie–Hellman key exchange (DH) is a method of securely exchanging cryptographic keys over a public channel and was one of the first public-key protocols as originally conceptualized by Ralph Merkle and named after Whitfield Diffie and Martin Hellman. DH is one of the earliest practical examples of public key exchange implemented within the field of cryptography.

In this post we would first explain how a Diffie Hellman key exchange works. Then we would dive deeper into the details of elliptic curves and its properties. Finally we would show how Elliptic Curves can be used for efficient key exchange.

Screening through hundreds of mail and prioritizing your work for the day is a difficult job. One kind of prioritization that is important is dealing with deadlines that are indicated in emails such as a slide deck or report due. The first step of calendarizing deadlines is to identify that a deadline is indeed present. We’ve tried to tackle this deadline tagging as an email classification problem using a Bayesian approach with the result being PMail. We also built an RNN based model which we compare with the Bayesian approach. We were able to show promising results with the approaches we took, which we detail in this post.

Stellar - the blockchain network based on a federated consensus protocol - is cool but it comes with a lot of complexities. However, as far as I researched, I found it’s not as stable as Ethereum. Builds have bugs (check out the issue list here) but the good news is, they have very active and well-managed support. A separate forum is there for that. You can ask or checkout questions there.

We were happy to have Prashanth Balasubramanian of lastbit.io over at Pramati Chennai last weekend - 8th and 9th of Sep 2018 - for a workshop towards understanding blockchain tech from the ground up.

Design frameworks and guidelines are a plenty for traditional 2D mobile applications, whereas AR applications and its updates are relatively new with no standard guidelines as such. We look at the current recommendations made by practitioners in the light of Don Norman’s design principles. Table of contents Primer Design Appearance Clues Interaction Feedback Experience Google guidelines in terms of Don Norman’s Design Conclusion Primer Almost all mobile AR applications are 2D applications with basic AR functions and its necessary to find ideal conditions for using the app in the real world.

Approximate biometrics are often required for effective online shopping experience, for example, for clothing, eyewear and footwear. We experimented with Mask-RCNN based object segmentation for measuring human feet with the intention of recommending appropriate footwear, which we talk about in this post.

This post will give you an insight of our experiments and results with AR tools like ARCore, ARKit and Vuforia in terms of features. To understand this blog better, kindly read our precursor to this one here. Since the features of these tools are largely familiar exploring and comparing them in terms of stability would give us new and better perspectives. Table of contents Fusion in AR Vuforia vs ARCore/ARKit Conclusion Fusion in AR Google and Apple have made a giant leap into AR space with the release of ARCore and ARKit.

I’ve been thinking about a few aspects of smart contracts and blockchain tech - especially public blockchain tech - and I have some lingering doubts that I’d like to capture here for any of you to attack.

With the developments happening in the realm of software and hardware breaking new ground daily, it is not far that our reality can be manipulated to suit our everyday lives and enhance our evolution. Welcome to a world of new reality. Augmented Reality manipulates existing dimension giving us a better world view. The rapid growth of mobile technology and ease of application development processes has given the push to develop Augmented Reality applications at a large scale.
