This blog post is an overview of testing focus behavior in web browser. During the work on Azure Portal I spent quite a bit of time on ensuring rich keyboard support. This requires appropriate focus management. When user press some keyboard shortcut, the focus should move to appropriate element. Focus behavior should be also tested very succinctly. As it is very easy to change (break) with even the smallest change in the HTML or JavaScript.

From time to time I receive emails with questions “How to become better/awesome developer?”, “Should I go to college?”, “what’s the secret formula to become ultimate programmer?”. Instead of answering the same questions over, and over again – providing only partial response each time – I decided to write this blog post...

Last month I had a pleasure to speak at ConnectJS and All Things Open conferences. ConnectJS ConnectJS was not only about JavaScript, but about web development in general. All Things Open is one of the largest Open Source conferences in the USA.

Last Saturday I had a pleasure to speak at Seattle Code Camp. It was an amazing event, which was free. There were over 50 talks, 500 attendees, and raffle with many prizes, e.g., Microsoft Surface Pro 3! Check out videos, code, and slides from my talks!

Last Thursday I had a pleasure to give a talk about Speech Recognition in the Browser at the Code Fellows in Seattle. Many people were surprised how easy it is to add speech recognition to your website with pure JavaScript. So I thought I will share a few code snippets here.

On July 1st I had a pleasure to speak at Seattle Node.js meetup about unit testing and Test Driven Development with Angular.js and Node.js, using TypeScript. In this talk I gave an overview of JavaScript testing frameworks, and tools. I also demonstrated how TypeScript can strengthen your tests by adding free unit tests (type checking) thanks to strong typing.

Yesterday I had a pleasure to speak at .NET Developers Association meetup in Redmond, about building web applications with TypeScript...

We all know that JavaScript has some bad parts. However, one of them is usually forgotten, and skipped in most of “JavaScript Bad Parts” lists on the Internet. It is a Date object. You can have hard time working with it, especially if you want to support time zones. In this post I would like to outline quircks of Date in JavaScript.

Agile Principles, Patterns, and Practices in C# by Uncle Bob is the best book about modern Software Development I have ever read. First section (chapters 1-6) is an Overview of Agile, Extreme Programming (XP), and TDD. Very good introduction to modern software development. Chapter 6. shows all these techniques by example, by creating “The Bowling Game” application...

Just as natural pearls grow from grains of sand that have irritated oysters, these programming pearls have grown from real problems that have irritated real programmers. I just finished reading Jon Bentley’s book: Programming Pearls. I read this book after Scott Hanselman’s and Jeff Atwood’s recommendations. The problems analyzed in this book are still actual. However, I think that today programmers face slightly different challenges...
