Mistake Proofing Deployment of Software Code

Posted on May 19, 2010 by John Hunter

This is a continuation of my previous post: Improving Software Development with Automated Tests. Lets look at a typical poka-yoke example. A USB connector must be put in the right way up – for the connection to work properly and the communication to occur as intended. So to mistake proof the process the connector won’t allow the USB device to be put in upside down – the hardware connection designed to not allow that type of connection. Using a deployment … Continue reading →

Improving Software Development with Automated Tests

Posted on March 8, 2010 by John Hunter

Automated software testing is a mistake proofing (poka-yoke) solution for software development. The way automated testing works is that software code is written that tests the software code of the application. This automated testing code test that business rules are correctly being followed by the code in the application. So for example, a user should not be able to create a new account without entering password. Then you create code that does not allow an account to be created without … Continue reading →

Baking in Quality to Software Development

Posted on August 15, 2009 by John Hunter

One of the reasons my organizations switched to Ruby on Rails for software development was the great integration with automated testing. We always wanted to have good test coverage on our software applications (which are web applications – some used only inside our organization) but didn’t actually find the time to do so. Since we adopted Ruby we have been doing much better in this regard. It isn’t just the switch to Ruby, of course, but the switch to Ruby … Continue reading →

Three Years of Real-World IT Projects In Ruby

Posted on July 16, 2009 by John Hunter

Nice webcast by Martin Fowler, Three Years of Real-World Ruby. This talk is probably only of interest to those of you in software development, but for them I think it is an excellent presentation. At work we have been use Ruby for the last 3 years and have found it to be a powerful language that helps make writing software applications fun. And that is important. By providing a powerful language and a rails framework that takes away much of … Continue reading →

Joy in Work – Software Development

Posted on November 25, 2007 by John Hunter

The wonderful cartoon in this link illustrates the all too common despair in work. Software programmers are more likely to really enjoy what they do. There are many reasons for this not the least of which is that they have a fair amount of control over their careers. If they don’t like what they are asked to do, the tools they are asked to work with… they will (more than others) leave for another job. Some managers get frustrated that … Continue reading →

IT Operations as a Competitive Advantage

Posted on October 26, 2007 by John Hunter

Operations is a competitive advantage… (Secret Sauce for Startups!) The example above is the tale of two Web 2.0 startups scaling to 20 systems during their first three months. The first team starts writing software and installing systems as they go, waiting to deal with the “ops stuff” until they have an “ops person”. The second team dedicates someone to infrastructure for the first few weeks and ramps up from there. They won’t need to hire an “ops person” for … Continue reading →
