Programmer/Tester Pair Programming

Pair Programming Advice

Extreme Programming gave us pair programming, a practice that is incredibly successful, wonderful beneficial … and hard to adapt culturally. Instead, people say they “pair when it makes sense”, which is code for “every now and again over a lunch hour”.

The main objection to pair programming is efficiency — it feels like two people doing the same job. If the pairs were split, development would be twice as fast! I can’t agree with that logic, but that is not today’s post.

Instead, today’s post is about effective pair programming when half the pair is a tester.

That’s can be scary, but with a little effort, testers can be incredibly helpful in pairing. Here are some ideas. Continued »

The Decline of The Coding School

In the past couple of weeks, Dev Bootcamp and The Iron Yard have both gone out of business.

It is hard to point to an exact reason. It could be market saturation, the intersection of price and willingness to pay, lack of companies that want to hire people at that skill level, or coding schools graduating people that aren’t capable of doing software development work. Many of the sentiments I am seeing online right now point at the latter. People seem to think that the quality of the students graduating from a coding school just isn’t very good. They are on the verge of being self-taught, and don’t understand enough of the important concepts to be successful in a development job.

Well…duh. How good would you be at anything after 12 weeks of introduction?

I think this points to a different problem in software.

Samsung BrightView HD Baby Monitor Review

Having a baby comes with a lot of gear. Some of it you need, some of it you don’t. Some of it is useful, and and some of it just takes up space and collects dust. My wife and I spent some time researching baby monitors before our son arrived. Luckily, someone made the decision easier by gifting a Samsung BrightView HD Monitor.

We have had the monitor about 8 months now so it’s been in use long enough to form a couple of opinions. If you are are about to have a child or are hunting for a gift for a friend or family member that is, read on.

Conway’s Game of Life As a Kata

Matt Heusser Matt Heusser Profile: Matt Heusser
Programming, Test Driven Development

In a previous article I wrote about Katas and how understanding them can help make programmers stronger. Most Katas are relatively simple: they are usually used for small tasks, like to score a card for a bowling game or to convert roman numerals into numbers. Few of them have a real display, a real model, or significant complexity.

But have you heard of Conway’s game of life?

Conway’s game of life is a program that simulates a universe under specific rules. In the past I have not understood Conway’s Game;it is typically described as a”multidimensional cellular automata“, and I never quite understood the definition of those words. In this article I will use my experience to describe Conway’s game of life in more common words, and also explain how we can use it to become better programmers and technical staff.

The Facebook Company Town

Facebook is creating a company town in Menlo Park, California.

A company town is a residential area, complete with schools, grocery stores, and entertainment built by one company. Employees of that company will live there for a discounted rate. And sometimes, these companies will relocate entire families to these developments as a way to bolster their workforce. The auto industry notoriously created entire towns like this.

Facebook is doing this in something they are calling the Willow Campus.

This is good for Facebook, but probably a bad idea for its employees in the long run.

Notes on the Amazon Acquisition of Whole Foods

Amazon made yet another company acquisition this week. This time they bought Whole Foods for $13.7 billion. Journalists are talking about this merger could resolve some issues in food supply. The general idea there being that there are neighborhoods in the US that don’t have easy access to a grocery store. Amazon having stake in Whole Foods could potentially mean that they can resolve some of this problem by using their new access to grocery products in combination with their nearly complete supply chain.

I am seeing some potential downsides to the merger that will take some time to flush out.

Why is Agile shaped Like a Waterfall

I have worked in several agile projects over the years and they overwhelmingly look like a phased waterfall project got squished into two weeks. Take each phase of a waterfall project — planning, design, coding, testing, delivery/maintenance — put them into a two week delivery cycle, and that is my experience of agile. I suspect that is the agile experience for a lot of other people as well.

I went to another local tech meetup yesterday. This was an introductory agile talk for people that didn’t have much exposure, but the content was driven mostly by audience questions. The content was very good. The speaker started drawing models of what a waterfall project looks like, what an agile project looks like, and then some process we like to wrap around modern software development.

That is when it clicked for me.

Thinking About ChatOps

Nashville is a meetup town, there is a meet up for just about anything you have an interest in. Have a thing for mechanical keyboards? Wt got you covered. Yesterday, I went to a combo meet up that covers testing, automation, and development all together. The theme was something I had heard of once or twice, but didn’t really know anything about, ChatOps.

My initial reaction to the term was “great, more fluff”. But, I kept my word. I attended the meetup, sat quietly and listened, asked a couple of questions, and learned something new.

This will be a lite into to ChatOps for people that were like me and had just heard the term once or twice.

Why Johnny Doesn’t Unit Test

TDD, Unit testing

charlieModern Unit Testing came out of Test Driven Development (TDD). The first Unit Test Tooling was designed for Smalltalk; jUnit and nUnit were strange, free plugins that were (shudder) open source. The people in the Alt.Net community found the Microsoft tool stack actively resisted TDD, continuous integration, and other technical improvements the XP and Agile Communities were making to the way software was delivered.

In technology terms, that was ancient history. Let’s talk about now.

Today, when I work with a company, they have likely heard of TDD.

They just don’t use it.

Here are a few patterns I’ve seen.

Director Comey comes to the IT department

comey

It was a long commute today and a long drive back, which meant I caught the majority of former FBI Director James Comey’s Testimony before the Senate and an hour of analysis.

About halfway through the analysis I realized that I had heard this story before. In fact it mirrored my own experience.

James Comey, former director of the FBI, had been through a political experience very much like my own … and one you might have been through, or might have to go through some day, as well. Continued »
