KeyNode with Node.js and Microsoft Azure

KeyNode is a application to issue and verify software license keys. Technology stack for KeyNode is Node.js, MongoDB and Microsoft Azure. I had built this functionality with (a cloud-based IDE with a built-in source code repository and debugger), mongohq (MongoDB as a service – now part of and appfog (Cloud PAAS built on top of CloudFoundry). It used SMTP/gmail to email license files. That was the version I created a couple of years ago to issue tamper-proof signed xml license files for CodeDemo (a code snippet tool for developers, presenters and instructors). For KeyNode (open source) I switched to a different toolset : Visual Studio Code and Windows Azure, simplified the code to remove signed xml file and open-sourced it on GitHub. Signed […]


Announcing New CodeDemo Feature – ZoomIt Integration

I am very excited to announce a new feature of CodeDemo. This feature integrates with ZoomIt and enables you to use ZoomIt much more fluently. ZoomIt is a great presentation tool. It helps speakers and presenters deliver very effective presentations. But many presenters are not using this great tool as much and as effectively as it can be used. The reason is that ZoomIt has a bit of a learning curve. It takes practice to use it fluently. You have a lot going on in your mind while you are doing a presentation. Using ZoomIt distracts you from your presentation. Practice helps you get over this distraction. A lot of presenters use ZoomIt very effectively with practice. But for the […]


Announcing CodeDemo

It is a challenge to use code snippets in presentations, demos and live coding sessions. I have struggled with this and seen many speakers jumping through hoops to assimilate code snippets in their demos. I had to create something to ease this pain. Today, I am announcing the general availability of CodeDemo. A tool for instructors, presenters and speakers who create instructional demos, record screen-casts or do live presentations. CodeDemo pastes code snippets into your favorite IDE without getting in your way. I decided not to open-source CodeDemo to challenge myself to an exercise in commercialization. I decided to learn about entrepreneurship, marketing, sales, licensing and other aspects of software commercialization. It has been an MBA’s worth of education so […]
