What Got You Involved in Open Source?

I did a very unscientific twtpoll recently regarding what brought each of us into open source. Plenty of people took the time to vote or retweet, so I thought I'd loop back around and let you know how it looked overall when the poll closed.

Come Undone - Argument Validation for Rocketeers

Validation is crucial part of development. From argument checks to validating workflows, pipelines, input/output boundaries we run checks to make sure that an application will behave correctly. I like to see the business processes before the implementation and try to express myself via code in that manner.

No SRP? No TDD for You!

I’ve been thinking about what makes TDD fail, and there are obviously few reasons that were discussed to death (Get it? Dead? TDD? Ok, let’s move on). What this gets you is a big, convoluted class that has tests, and some small internal, simple data classes.

Why GPM is the Right Go Package Manager

GPM + GVP has worked well for me, and I find it much better than vendoring or living at the cutting edge of every dependency's repository. I've implemented it on projects large and small, and it feels clean. I've used it to manage builds and CI. Overall, I've found it to meet my needs better than any other solution.

Test-Driven Development Saves Time — A Story

I recently had an experience writing code that proved to me, once again, that using Test Driven Development really is faster than the way I have been working. I easily saved half a day on each project by using Test Driven Development.

Release Testing is Risk Management Theatre

The adoption of Continuous Delivery often leads to the discovery of suboptimal practices within an organisation, and the Release Testing antipattern is a common example. What is Release Testing, and why is it an example of Risk Management Theatre?

Integrated Tests are Not Feeling Well--Long Live Design!

It's 2014, but there's still a widely held belief that integrated (or end-to-end) tests should be favored over unit tests. A belief that Test-Driven Development does not have a beneficial influence on the quality of your tests and code. So today I'm repeating a few things I have been writing about in the last years.

The Rise of the DevOps Movement

This ultimately comes down to the idea that the involvement of developers doesn’t end at their last commit. Collaboration is key which allows every developer to play a key role in keeping the site up and running, for more happy users. After all software with no users has no value.

Web Development With PhpStorm

The main reason why I used Sublime Text was for speed and simplicity, Sublime Text at it's basic level is a text editor, which has been extended into an IDE. Everything about it was built for speed, which makes sublime one of the quickest and easiest text editors to use.

Free as in Beer Has Caused Heartbleed (and Much More)

Heartbleed is a bit over one month old now. Today, we’re going to look into how wrong we have been in assuming that Open Source software is more secure than commercial software, because of our thinking that source code is open and that many developers are looking into it.

Using Drone and Docker for Continuous Integration

I've tried CI systems ranging from Bamboo to Jenkins, and I always feel like I'm either pushing against the limits of the tech or tiptoeing through a mine field of possible misconfigurations. I don't feel that way with Drone. The "disposable" Docker environment is an absolutely perfect way to test code.

What's Wrong with Test-Driven Development (TDD)

I was asked to talk about the problems of using TDD – being me I’ve decided to do the exact opposite, this session was names “what is wrong with TDD”. I felt that one of the major issues is that TDD looks weird, it’s counter-intuitive, and convincing developers to actually try it hard and requires a mental leap of faith.

Illustrating Our Continuous Delivery Matrix

In VietnamWorks.com we managed to implement Continuous Delivery (CD), and we used following image as our reference. But why did we decide to use CD? We wanted to build the right features for our products, avoid as many risks (fail fast, succeed faster), increase our release cycle, and continue a stable product.
