  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...

  RAM is the new disk...

With the proliferation of "real-time" web applications and systems that require massive scalability, how are hardware and software relating to this meme? Tim Bray, in his discussions about grid computing before it became such a hot topic, pointed out how advances in hardware around RAM and networking were allowing for the creation...

  Python internals: adding a new statement to Python

This article is an attempt to better understand how the front-end of Python works. Just reading documentation and source code may be a bit boring, so I’m taking a hands-on approach here: I’m going to add an until statement to Python. All the coding for this article was done against the cutting-edge Py3k branch in the Python Mercurial repository mirror. The until statement Some languages, like Ruby, have an until statement, which is the complement to while (until num == 0 is equi...

  A Different Kind of Technical Interview

Everyone who's been programming professionally for a while knows the standard format of the technical interview. You go in, there's a whiteboard in the room, and you write code on it to answer questions.Everyone also has the same basic complaints about these interviews. In a normal work environment, you have access to an API or search engine, but at a whiteboard you don't. Whiteboard questions generally don't include much in the way of overall design, and they're typically limited to simple algo...

  In defence of Objective-C

An unashamed apologist’s perspective on the loveliest language i’ve worked with.I’ve worked with a lot of programming languages in my time. Not a huge number, mind you, but enough that i can say that i’m open minded and seasoned about it. And, as they say: ‘Don’t feed the trolls’ – well, i’m about to do exactly that: feed the trolls at work who love to rag on about how awful obj-c is! So here i go, foolishly treading where no sensible...

  Vim: revisited

I’ve had an off/on relationship with Vim for the past many years. Before, I never felt like we understood each other properly. Vim is almost useless without plugins and some essential settings in .vimrc, but fiddling with all the knobs and installing all the plugins that I thought I needed was a process that in the end stretched out from few hours to weeks, months even; and it the end it just caused frustration instead of making me a happier coder. Recently, I decided to give Vim ano...
