In this post I’m going to try to explain in simple terms how a camera meters, and why you should take control of metering to achieve good shots.
Your meter is calibrated to produce the correct exposure for average scenes.
As it turns out, a good rule of thumb for average scenes is a particular shade [...]
It seems after In/Out (aka Backpack Journal) came out, there have been at least a few clones.
I created an app (actually long before in/out) called WFH (Working From Home), a way to quickly share status with your coworkers. You can pick your status from a dropdown for every day of the coming week, and [...]
The term Cloud Computing is on the rise according to google trends. But what does it all mean? Just like “Web 2.0″ it’s an overloaded phrase with tons of connotations and many attempts at definition. While perusing a cloud blog by James Urquhart, I was inspired to try to define the term myself. So here’s [...]
More and more studies are published every day on the exceptional benefits of napping. Today I found a great link on del.icio.us that gives a great overview of different lengths of nap times and their benefits on cognition. Naps reduce stress, increase alertness and productivity, boost memory and learning, stimulate creativity, and boost the immune [...]
For some Friday fun….I’m not picking on the Apache foundation. But, see if you can guess which products are being described below. Taken from the first paragraph descriptions of four different products.
The open source movement has fantastic engineers. Now what we need are some marketing minded people to devise clear and concise mission statements for [...]

What I really love about this idea is that instead of reinventing the wheel, they’ve decided to be API-compatible with EC2. Not only does this make adoption easier for them, [...]
A new section of the Yahoo Design Pattern Library (YDPL) is on Social Reputation. Besides having a nice library of software/UI patterns at the YDPL, apparently they’re doing social behavior patterns as well.
Yahoo identifies five different competitiveness levels for social communities (Caring, Collaborative, Cordial, Competitive, Combative) and recommends different ways of handling reputation in your [...]

I was recently designing an application that needed to execute some long running requests against an external host. If you’ve ever tried doing something like this in Rails, you’ll find your mongrels will block up waiting for the request to complete, bringing [...]
If you’ve deleted a bunch of files in your directory, here’s a handy bash alias to git rm the changes into your index.
alias gitrm=”git stat | grep deleted | awk ‘{print $3}’ | xargs git rm”
Update: turns out git add -u takes care of deleted files.
Sometimes you have a data migration that creates or modifies records in some way, and you would like to test it in your unit tests right? Except that Rails typically just clones the structure of your dev database, not its data. So how do you test that a migration succeeded? Simple, just invoke it during [...]
