Simple Animation in the HTML5 Canvas Element

HTML5 is generating all kinds of buzz these days. Some of the buzz is about HTML5 being a replacement for Adobeâ€™s Flash. I donâ€™t think itâ€™s there yet but itâ€™s certainly on the way to changing the way content is presented on the web. This is a description of a very simple animation in an HTML5 canvas element. It is coded for readability and not for optimized operation. Weâ€™ll add a canvas element to a web page and then use javascript to draw on it. We will...

Building a Modern Web Stack for the Real-time Web

The web is evolving. After a few years of iteration the WebSockets spec is finally here (RFC 6455), and as of late 2011 both Chrome and Firefox are SPDY capable. These additions are much more than just "enhancing AJAX", as we now have true real-time communication in the browser: stream multiplexing, flow control, framing, and significant latency and performance improvements. Now, we just need to drag our "back office" - our web frontends, app servers, and everything in between into this cen...

Why I Will Never Feel Threatened by Programmers in India

I got a call from a friend of a friend the other night. It was a fellow with whom Iâ€™d talked 11 months ago about a project he and his partner were looking to start. We established then that I wasnâ€™t the guy for him, that I was likely too expensive for their big-dreams, small-means budget. Fast forward to present day: their project is still not launched, itâ€™s still not right. Theyâ€™ve paid for something between 600-700 hours of development with a firm in India, an...

A Solution to CPU-intensive Tasks in IO Loops

Back in October 2011, Ted Dziuba infamously said that Node.js is Cancer. A provocative title to a provocative article. The only thing it didnâ€™t really provoke in the commentary was much thought ;) Zing. My interpretation of the article is that Ted holds up the classic blocking-IO process-per-request (or thread per request; same difference) model as superior. Yet we all remember where the blocking-IO forking model got Apache in the early days. ...

CSS3 Animation With jQuery Fallbacks

In today's post, we'll be taking a look at how you can use CSS3 transitions to power your application's animations with jQuery's .animate() method as a fallback where transitions aren't supported. The benefit of transitions is that unlike JavaScript based animations, they're hardware accelerated in certain browsers and mobile devices, resulting in a potentially smoother overall animation than you would normally experience. In a lot of cases your code will work seamlessly with the solut...

Python Patterns - An Optimization Anecdote

The other day, a friend asked me a seemingly simple question: what's the best way to convert a list of integers into a string, presuming that the integers are ASCII values. For instance, the list [97, 98, 99] should be converted to the string 'abc'. Let's assume we want to write a function to do this. The first version I came up with was totally straightforward: def f1(list): string = "" for item in list: string = string + chr(item) return string ...
