12 - Implementing Continuous Delivery While keeping software production ready throughout its lifecycle and optimizing your delivery process for shorter cycle times might seem like a good idea to you, your colleagues might not share your excitement. In this webinar, Jez Humble discusses ways of implementing continuous delivery, and shares stories from companies who have successfully worked to improve their capability in continuous delivery.

I served as lead developer on this award-winning crowdsourcing platform at the University of Iowa Libraries. The code has been made freely available on Github and has been used by over 20 research libraries and archives around the world, including Yale University, Oxford University Museum of Natural History, The Newberry Library, University College Dublin Archives, […]
I have been watching a lot of video conferences on security and I'm wondering what will happen in the next couple of years.
Prefix notation I’m a big fan of the prefix notation. It makes everything appear the same (if-statements, function calls , etc). I like how it removes the need for operator precedence rules. All the parentheses Once you get into learning Clojure and you have written a small application, you don’t really see the parens anymore. Sure, sometimes you still get the Unbalanced parens error but those are easy to spot. If you are afraid of....

The Recipe for Classification One important task in machine learning is to classify data into one of a fixed number of classes. For instance, one might want to discriminate between useful email and unsolicited spam. Or one might wish to determine the species of a beetle based on its physical attributes, such as weight, color, and mandible length. These “attributes” are often called “features” in the world of machine learning, and they often..

The Blessing of Distance We have often mentioned the idea of a “metric” on this blog, and we briefly described a formal definition for it. Colloquially, a metric is simply the mathematical notion of a distance function, with certain well-behaved properties. Since we’re now starting to cover a few more metrics (and things which are distinctly not metrics) in the context of machine learning algorithms, we find it pertinent to lay out the defi..

I like the idea of Android home screen widgets. I like to visualize information, to get it quickly and perform common tasks in a single tap. Even though Android market is flooded with useful and not-so-useful widgets of any type and price, I was looking for a geeky way to make my own widgets. why? Normally, I need either very simple widgets (like clock, calendar, weather, battery level) or very specific ones (say, a calendar that draws a da..

I’ve been working on a puppet module for gluster. Both this, my puppet-gfs2 module, and other puppet clustering modules all share a common problem: How does one make sure that only certain operations happen on one node at a time? The inelegant solutions are simple: Specify manually (in puppet) which node the "master" is, and have it carry out all the special operations. Downside: Single point of failure for your distributed cluster, a....

My entry for the js13kgames challenge was cutting it too close to 13kb and I needed more room, so I decided to cut out the one image that I had - the Twitter logo for the sharing link at the Game Over screen.
Working on a class in our application, I discovered that it was being included before a number of constants it used for its members were even defined. Puzzled on how this had never been a problem I started to experiment; echoing the member at the bottom of the class file after the class closed showed the expected CONSTANT_NAME. I was very confused at runtime the value of the member in the constructor and elsewhere in the class appeared co....
