I usually use Vim and the ‘:set number’ when I want to refer to line numbers in a file but Chris showed me that we can achieve the same thing with e.g. ‘less -N data/log/neo4j.0.0.log’.
I’ve been hacking on a product taxonomy and I wanted to create a ‘CHILD’ relationship between a collection of categories. For example, I had the following array and I wanted to transform it into an array of ‘SubCategory, Category’ pairs...
During our induction into the IBM family, one of our new colleagues told an anecdote about a firm that outsourced its mobile application development. Managing the relationship of outsourced work with what is being developed in house is a challenge similar to what manufacturers face with their supply chains.
I live-coded a new gem called Ruby::Enum at NYC.rb on Tuesday. This library adds enum-like functionality to Ruby. Here’s my checklist for creating a new gem.
Respected institutions like the Harvard Business Review, the Economist and others are publishing studies that show that the average CEO is unhappy with the status quo of their own technology shops.
A comparison of the configuration management tools Puppet and CFEngine.
“Any software programmer that does not do unit testing is a reckless coder,” declared Lopian. “Unit testing is an essential part of any software development process. It allows you to deliver working code, with fewer bugs, faster."
Let's look at how to get visibility into an important component of any complex system: the messaging queue. Specifically, let’s look at how to trace a job from Rails using Resque.
In Grails we can write unit tests for controllers. We can check for example the results from a redirect() or render() method.
I found myself thinking – what are steps I take when writing a new unit test? I’ve been writing them for so long and never noticed I’ve been following a “methodology” of sort. And so without further ado – here is the steps I take when writing a new unit test...
Most people within technology feel a healthy amount of concern about how they’ll navigate so many disruptive changes happening simultaneously. Each of what Gartner calls the Nexus of Forces, social, mobile, cloud, and information is highly disruptive on their own.
Version control is becoming a ubiquitous part of the “DevOps movement,” and we talk through what level of understanding should be expected, what level of training should be provided, and whether those are different for different teams or different tools.
On average, web sites are getting more secure each year: the average web site had over 1,000 vulnerabilities in 2007, and only 56 in 2012. SQL injection, the most popular and most serious attack vector, is found in only 7% of their customer’s web sites.

From OpsCode, a thirty-minute tale on the triumphs and hurdles Turner Broadcasting System's team encountered as it attempted to implement DevOps and deploy Chef.
At an insurance company, I encountered an application that had been in place for thirty years. Classic flat-file, mainframe COBOL. And decades old. It had never been replaced with a packaged solution. It had never been converted to a SQL database. It had never been rewritten in VB to run on a desktop.

The refactored version partials the data while it's incomplete and executes the partial'd function when all of the data is available.
Dogfooding is a great idea, but it’s no substitute for usability testing. I get the impression that some products, if they’re tested at all, are tested by developers intimately familiar with how they’re intended to be used.
