Why I Created Dev Empathy Book Club

I was just a few months out of the Flatiron School, had gotten my bearings in the codebase at my first job, and was starting to take on more responsibility. I was sitting with a product manager—let’s call her Sierra—trying to explain the technical impact of a product idea she had proposed. And I was frustrated.

No matter which way I explained it, she just kept getting confused. Why couldn’t she understand that making these changes would drastically increase response time on a critical endpoint? It was a simple workflow involving 2 microservices and a NoSQL database, and she didn’t even have to understand the details, just how they were connected together on a high level.

At some point, I realized: No one had ever given Sierra any level of technical explanation of the system whose development she was supposed to guide every day. Instead of going further with the conversation, I asked, “Why don’t we set up a meeting just to describe the basic outline of the system? Nothing overly detailed, just enough to allow us to have a conversation about how product concepts will impact the real-life product when they’re translated into code.”

To my surprise, she agreed. To my further astonishment, I actually enjoyed the meeting more than any other I’d had since beginning my software development career. We slowly built up a diagram of the parts of the system relevant to her job, clarified confusing points, and made sure every bit of explanation was clear to her.

At the end of the meeting, Sierra thanked me and said, “You know, no one’s ever done this for me. This is going to significantly improve my ability to come up with ideas and communicate with developers. I’d really like to understand more about the technical elements of the project, but there never seem to be opportunities for me to learn.”

At that moment, I realized something that has become a theme in my career: The most significant impact you can make on a product isn’t through design, code, marketing, sales, or customer support. It’s building bridges, enabling people of varied backgrounds and skills, each with their own perspectives and spheres of understanding, to work together through effective communication.

The 3 Keys to Software Quality

Why do software projects fail?

This question is difficult to answer precisely because there isn’t a single answer. Sometimes the blame falls to technical debt which hamstrings scalability, the ability to ship new features, or the ability to respond to market demands. Other times it’s the lack of business model, which sinks the entire company. In certain situations, various parts of the organization not seeing eye-to-eye is the culprit; the lack of shared vision causes sales to over-promise, engineering to develop the wrong things, or marketing to pursue the wrong strategy.

The causes are many and varied, yet somehow as engineers we focus a lot on “Good Code” (however we choose to define it), which fails to address most of these problems. Why?

Reflections on 8 Days of Blog Posts

I started the 8 Crazy Blog Posts Challenge as a way to stretch myself and get back in the habit of writing. As in writing software, blogging regularly is difficult when there’s no pressure to ship.

It certainly got me to release more material than has been my recent practice, but it’s worth analyzing the process, the outcomes, and the cost.

How to Give a Great Tech Conference Talk

People come to tech conferences for many reasons. They want to hear about new ideas and technologies, to be inspired with the latest and greatest of what the programming community has to offer.

But once people are actually at a conference, especially a larger conference, the number of things to do and to absorb can be overwhelming. There are talks, maybe even multiple talks at once, there’s the hallway track, vendor booths, and of course the great big world outside where people escape when they want a break. Everyone competes for attention, offering excitement, swag, fun hacking activities, and/or the alluring prospect of job opportunities.

Then there’s the new practice of posting talks online. This opens up talks to new audiences who couldn’t make it, which is fantastic. It also means that if the community loves a talk, it could be see by thousands more people than were at the conference! The downside is that conference attendees may be more likely to skip talks because they’re all online later anyway, meaning that speakers lose the opportunity to build off the speaker-audience interaction.

What’s a speaker to do?

Make It Easy to Do the Right Thing

There’s a great Kent Beck quote which should be etched on the mind of every serious programmer:

The immediate context of the quote is changing code. But truth be told, it actually applies to a whole host of problems on multiple levels. It can help us fundamentally alter our practices, our teams, and all elements of the quality of our software.

Let’s understand how and why.

Diversify Your Learning

As a programmer, I’m privileged to be part of a field where learning is thought of as part of my job. Many enlightened companies specifically dedicate time during the workweek for exploration and side projects. Companies pay for their employees to attend conferences, buy books, and sponsor subscriptions to online learning resources.

There’s a wealth of information I can access, and more is being created constantly than I could ever hope to consume. Prioritization is key. What should take precedence in my learning? What will contribute most to my professional development as a programmer?

There are many approaches, ranging from “Follow your heart and specialize,” all the way to “Learn a bit of everything.” Some emphasize learning a full stack of technologies, others think you should just get really good with the tools you use every day.

My approach falls somewhere in the middle, and I’d like to share it with you. It starts with a bit of wisdom imparted over 1,600 years ago.

This Is Your Brain on Ruby

There are plenty of ways to write a FizzBuzz program in any language, particularly Ruby with its TIMTOWTDI philosophy. Beyond the naive implementation, you can write it in one line, using only Procs, etc. Yet this still might be the oddest, most inscrutable implementation you’ll ever see:

Go ahead, paste it into irb and check that it works. I’ll wait here.

Wait, how does that work? Welcome to the wonderful world of BrainRuby. Check out the explanatory video, or read on.

Automating Empathy: Test Your Documentation With Swagger and Apivore

If you’re responsible for an API, you may have noticed that API documentation is painful to keep in sync with your code. A tremendous amount of cognitive overhead is added by having to remember everything you’ve documented and update it any time a change happens.

Also, you probably fail a lot. And you’re not alone! Most teams fail miserably at the task of documentation upkeep. It reaches the point where you have to wonder:

  1. Is there a problem with the team if we can’t get this right?
  2. Is this an intractable problem that is destined to plague us, and all API maintainers, forever?
  3. Is the problem with the task itself?

Most of the material you’ll find centers around practices that will help the team prioritize documentation, organize it better, etc. I think that’s a load of hooey (pardon my French). Documentation is really hard because we haven’t figured out how to automatically check that it’s accurate, and people can’t reasonably be expected to keep it all in our heads.

Until now.

Git Commit Message Anti-Patterns

Have you ever experienced this before? You’ve just finished a unit of work, and you’re rightfully proud of what you’ve accomplished. All that’s left is to commit and push. So let’s just git commit -am "… what exactly? Filling in that line can be really tricky, and you never know when another developer—or future you—will curse your name for an unhelpful commit message.

Fortunately, many common harmful practices can be summed up into a few anti-patterns. In this post, we’ll cover 5 critical mistakes to avoid.

8 Crazy Blog Posts!

I have a confession to make. I’m embarrassed by my blog.

I’m certainly proud of (most of) the content. It’s shown significant development in complexity and depth since I started. But I have a lot of ideas running around my head all the time, some of them even good ideas, and I’d like the blog to reflect more of them.

So I’ve decided to give myself a Chanukah gift: I’m requiring myself to make every effort to come up with one blog post every day of Chanukah.

This probably makes you wonder a few things.
