It’s been way too long since my last programming focused blog post, so let’s try to rectify this situation: Background A couple months ago, Twitter made available their Streaming API. This provides developers with a very efficient way to tap into the public Twitter stream. All you need to do is open and maintain a single HTTP connection, passing in a few filter parameters.

Yesterday, Amazon finally delivered the Magic Mouse that I had pre-ordered a couple weeks ago. (Since I was in the market for a Bluetooth mouse anyway, this seemed like a perfect excuse to pick one up…) The final verdict is still out, but I figured I’d share my initial impressions.

If you own a MacBook Pro and would like to upgrade to more than 4GB of RAM but think that your model does not support this, you may want to read the rest of this article.

I knew that the standard config with 2GB of RAM wouldn’t be enough for my purposes, but I also wasn’t about to spend a ridiculous amount of money on an official memory upgrade from Apple, so I picked up two cheap G....

It’s been a while since I completed my first iPhone development project, and I figured I’d finally write up my initial experience with this platform. A bit late, but better than never… To put this into perspective, here’s a brief summary of my previous professional programming background: I worked with C++ back in University but quickly adopted Java in 1998 and never looked back (good riddance to pointers and manual memory management!...

If you need to perform any time consuming work in your Rails actions, you’ll probably want to offload this into a background job.

The nice thing about Workling is that it provides an abstraction layer that allows you to decouple your actual background job implementation from the background execution strategy. For example, in our development environment we are using the Spawn runner (which simply forks the Rails process for each background job), but we need a proper, queue based runner in production....
