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.
Recently I needed to write up a new Powershell script to automate some actions independently of our major release cycle. This took me down a road with two possible options.
This five minute Ignite talk argues that DevOps consistently beats out traditional IT ops strategies, taking a look at a 2013 survey.
This week we're talking to Michael Sahota, Certified Scrum Master, active member of the Agile community, and co-organizer of Agile Tour Toronto.
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.
I recently refactored some code that takes longs from two different sources to compute one value. The code originally stored the longs and called a function when all of the data arrived. 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.
Grails has great support for testing. We can unit test controllers, taglibs, services and much more. One of the things we can unit test are views and templates.
New Augmented Search technology for log data is now available, built to help developers and testers understand application data faster. The idea is to add auto generated intelligence layers based on user search context.
The Mikado Method is a process for surfacing the dependencies in a codebase so that you can systematically eliminate technical debt. It gets its name from a simple game commonly known as “pick-up sticks,” in which you try to remove the Mikado stick without disturbing the others.
There have always, it seems, been people for whom attribution and citation really matter. Some of them passionately engage in arguments that last months or years, debating the merits of comma placement in written citations for the work of others. Bizarre, right?
We tried a new retrospective prioritization/voting technique this week that worked really well. After we had generated and discussed all of our ideas for improvement, it was clear to me that there were several excellent ideas and it would be hard to use our regular voting technique to single out one or two.
If you have been bitten by the process bug, like me, then you always see parallels between business, process, and everyday life.
If the ALT+F templates show poor IT Operations performance, the next steps in the Adapt and Plan phases are to identify optimal targets to achieve operational excellence and best-in-class status and then to set the stage for an Agile and Lean transformation strategy that should be executed on two levels...
The Grails team is extremely pleased to announce the releases of Grails 2.1.5 and 2.2.2 and 2.3 M1.
