Charlotte IOT – Programming Smart Contracts on Ethereum Blockchain

tewari

Charlotte IOT – July 2018 You will not want to miss this chance to learn about Blockchain, a technology enabling an entire IoT ecosystem! It has a distributed database for all the transactions, which eliminates the need for the third party to authenticate the transactions. The database ledger is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Charlotte IoT wants to thank Ash Tewari for traveling from Raleigh to share his extensive knowledge and experience around Blockchain. In this session, Ash will introduce you to the world of Blockchain programming. You will learn about Ethereum and how to program Smart Contracts on Ethereum Blockchain. You will learn how to deploy and test your code on a public Ethereum […]

Ethereum Blockchain-As-A-Service in Azure Cloud

tewari

Ethereum Blockchain (EBaas) as a Service provided by Microsoft Azure and ConsenSys allows for enterprise customers and partners to play, learn, and fail fast at a low cost in a ready-made dev/test/production environment. It will allow them to create private, public and consortium based Blockchain environments very quickly in Azure. In this session, you will learn how to get started with prototyping building blocks of a decentralized application using EBaas in Windows Azure. Venue: Triangle Azure User Group Slides : download.

Getting Started with Smart Contracts on Ethereum Blockchain using Visual Studio

tewari

Smart Contracts are an exciting innovation built on blockchain technology. It is a way to execute code in a trustless, decentralized and transparent system. Ethereum is a decentralized platform to run smart contracts using a variation of Bitcoin’s blockchain technology. In this session, you will learn how to write smart contracts in Visual Studio. You will learn how to deploy them to public Ethereum blockchain and a private/consortium blockchain as a service in Azure. You will be introduced you to Solidity – the programming language used to write smart contracts. You will get familiar with the tools and technology around this exciting, promising and relatively new innovation. Presentation Slides are here: download.

Universal Apps

The story of Windows Universal Apps is the result of advancements in three areas: The platform convergence between Windows 8.1 and Windows Phone 8.1 The (ongoing) unification of Windows and Windows Phone stores. Shared Projects and other enhancements in Visual Studio 2013 Update 2 to support cross-platform development. I have written about my experience in converting an existing Windows 8 app, CensusMapper, to a Universal App on the AIS Blog. Read the article here. I have also created another Universal App, LRMS, using Windows App Studio. This app is available in both Windows and Windows Phone Stores. I gave a presentation at the Raleigh Code Camp this past weekend : Creating Universal Apps for Windows Phone 8.1 and Windows 8.1. Thanks […]

NoSQL in Windows Azure

tewari

You may have questions like these – What are my NoSQL options in Windows Azure? Can I run MongoDB on linux on Windows Azure? Why would I want to do that? Which one of the NoSQL options are available as managed services? Are all kinds of NoSQL databases available? Are there any limitations? What are options for data analytics? Or may be you have questions like these – Is it true that NoSQL databases don’t have schema? Do they have indexes? What about Views? Should I choose MongoDB or Redis? What is eventual consistency?  In this presentation, you will learn all about NoSQL technologies in Windows Azure Cloud Platform. And you will get get answers to questions like these. Carolina […]

Using Layer Diagrams – Keeping your MVVM code from turning into spaghetti

tewari

Raleigh Code Camp 2013 is wrapping up this afternoon. The venue and the crowd was phenomenal. I really enjoyed presenting “Using Layer Diagrams – Keeping your MVVM code from turning into spaghetti”. Thanks to everyone who attended the presentation. John Sonmez, Our Keynote Speaker, made my day by accepting my request to attend my presentation. It was awesome to have him in the audience and to get feedback from him! I did not get the time to complete the raffle at the end of the presentation. But the folks who won the raffle should be getting an email from me with instructions to download their free license of CodeDemo (Professional). The presentation slides can be downloaded from here : download.    

Win Advanced MVVM Book

tewari

I am presenting a session on Building WPF Application using MVVM (Model-View-ViewModel) on May 15th at the Carolina Code Camp 2010. I will dissect a Sample WPF MVVM application and then highlight the most important aspects of the MVVM by coding a brand new ViewModel and incorporating it into the application. You will learn about the Roles of the MVVM triad, the advantages of using MVVM and Characteristics of the ViewModel. Attendees will be eligible to win two copies one copy (see below) of Josh Smith’s Advanced MVVM book as well as a few other WPF Books. { I will be giving away one hard copy version of the book instead of digital versions due to concerns about DRM protection […]

Session Recommendations for SoCal Code Camp @ USC

tewari

SoCal Code Camp is coming up on November 21st & 22nd 2009 at University of Southern California, Los Angeles. There is just an incredible lineup of sessions. If you are trying to make up your mind about the sessions to attend, here are my recommendations – 1. Attend as many of Llewellyn Falco’s and Woody Zuill‘s sessions as you can. Specially, Unit Testing The Easy Way and one of the Dojo sessions. Any one of these sessions will make your entire trip worthwhile. 2.Kristian Hermansen’s Get Hacked Live .. 3. Stacey Broadwell’s Using Technology & Social Media to Target Candidates & Jobs should be very useful. I attended her recent presentation at L.A. Dot Net @ UCLA, it was very […]
