“Whatever your political persuasion, however you voted (or didn’t vote), for whomever you cheered or jeered, there is one truth that must be faced — a truth obscured, I think, in the fevers of our own tribal instincts — and that is this: a person’s salvation is of their own making.” (read more on Medium)
This month I delivered a presentation called Github is Your Resume Now at LaunchCode STL. Slides are available through the presentation link. The presentation was not recorded live, but I plan to make a screencast available in the near future. Thanks to all the LaunchCode candidates who showed up, I enjoyed meeting everyone!
I’ve published an article on Medium.com about the ES2015 Map and WeakMap types.
I get lost in my own inner philosophical world when I ride my bike. I don’t know, maybe it’s the scenery. Maybe it’s just all that fresh air rushing by, or the pulse of blood through every inch of my body. It gets me thinking, whatever it is.
And today, as I rode, I thought about motion. Have you ever tried to stand still on your bike and maintain balance? One might think that standing still is the safest way to be, that moving on a two-wheeled bit of aluminum at high speeds is the danger. But the truth is that you only have stability when you’re moving. When you stop, no matter how hard you try to stay upright, you’ll be putting a foot down to stop the fall eventually.
Maybe life is a bit like that. Standing still is deceptively comfortable, but it’s really the most unstable state in which one can be. Movement, motion, forward momentum–those are the soul’s lusts.
I tried to imagine a world with no motion, and it came to me that all of our senses–sight, smell, touch, taste, hearing–all of them require motion to convey anything to our minds. You only feel what moves against your skin. You only smell what wafts your way. Sight is light mercilessly barraging your eyeballs and hearing is vibrations and pressure changes stroking your eardrum. The chemical interactions that produce vibrant flavors is taste to your tongue. All of it requires motion.
So motion gives us stability and knowledge of the world. And attempts to stop motion are frowned on by nature. Inertia compels us in the directions we move. When I ride the switchbacks to the river my brakes remind me the whole way down how much work they do to stop my forward motion.
It makes me feel unstoppable and free, and I think that is something humans need to feel often.

Obviously, the scope of each topic is greater than its chapter, but the book’s goal is to be a quick but thorough introduction to the core concepts in each framework and library. The source code is non-trivial and executable, so a reader can see concepts in action while following along in the text.
Some of the technologies covered have aged (like fine wine!), and some are much younger, but we believe that each has staying power and stands well among its peers. Between us we have used all of these technologies in our own projects and in production deployments, and while we cannot claim complete expertise, we humbly submit that, to the best of our knowledge, the information here is both sound and practical.
We sincerely hope that this book brings much value to you and your team!
My only beef with Bleeding Edge Press is that I was asked to review Developing a gulp Edge after I had already spent weeks pouring over documentation, github issues, and StackOverflow questions ad nauseam while trying to learn Gulp on my own. Developing a Gulp Edge is the book with which I should have started.
The real value of this book, however, lies in the fact that it helps the reader navigate a rapidly shifting Gulp landscape by identifying community-blessed alternatives to blacklisted plugins, such as gulp-browserify. This, more than anything else, caused me a great deal of confusion when I initially started using gulp. Google search results lack historical context, so articles that often appeared first in search results actually delivered bad or outdated advice. This book avoids all that by keeping the reader on the straight-and-narrow, by explaining why certain practices have been abandoned in favor of others.
The last three chapters are particularly strong. They move the reader beyond basics into advanced Gulp automation. This includes tasks which enrich the development environment itself, such as running a development server, syncing browsers across devices, and automatic cache busting. The reader is also shown how to speed up builds with caches, so that continuous integration processes and watches run as fast as possible.
The last chapter is a full tutorial on building custom Gulp plugins. This is where the authors really lets it all hang out, as the reader is introduced to vinyl File objects, through streams and buffer manipulation techniques. Once the reader has finished implementing each example he is left with a useful plugin accompanied by unit tests, a code coverage implementation, and a Travis CI configuration–all project features that the Gulp community strongly encourages, nay outright demands, of any Gulp plugin author or contributor.
Developing a Gulp Edge has a single Appendix containing a long and very useful list of Gulp plugins for most any development task imaginable. I will refer to this Appendix often, and with fondness.
While this book does have a few spelling and grammatical errors its overall style is clean, friendly, and concise, and the content is structured quite well. Each chapter, each example, builds on previous knowledge in such a way that reader has a strong grasp on what Gulp is, what it does, and how to leverage it for daily use.
This code ensures that when the method `bar` exists on the prototype for Foo, the instance implementation of `bar` added in Foo’s constructor won’t be applied. So the instance implementation is kind of like a “default implementation”. This might really only be useful if a constructor function’s prototype property changes over time, a scenario that is not likely to occur in most applications.
This came in handy for me while writing unit tests, however. I have a complex mock that creates an object for which I control both the prototype used and the constructor function. What I do not control, however, is how the object is instantiated within the module I am testing because it is ultimately instantiated through a factory function. So I can’t intercept the object and just “append” an overriding method onto the instance; the function must be added to the prototype before the object is even created by the factory function. But if a method is created on the prototype AND the constructor defines a method of the same name, the constructor function’s method will take precedence in the prototype chain. Instead, I used the conditional logic shown in the gist above to ensure that the method I define on the prototype (which I control for the purposes of the test) is the one that will be used.
There are probably much better ways to accomplish this. Conditional constructor methods reek like a code smell, so I would probably not implement anything like this in production code. For a little unit test mock, though, it is a fun thought experiment.
Right now it iterates through every jshint option and prompts the user for a setting value. Each setting has a default value, which may be chosen by simply hitting enter at the prompt. Defaults were chosen based on a simplistic criteria, one which I tend to refine a bit:
- the default for enforcing options is always TRUE
- the default for relaxing options is always FALSE
- the default for environment options is always FALSE
I also want to add some better command arguments, such as being able to specify known settings via a switch (e.g.: –use=eqeqeq=true;forin=true). The user wouldn’t be prompted for these settings since they’ve been specified already.
The –live=true switch forces hintme to screen-scrape the jshint options page and then prompt the user for the most “current” options instead of using the options.json file included with the hintme module. This is probably a tenuous way to get the most current options but it works for now.
I intend to add a suite of unit tests soon, and probably break up the code a bit. Releases < 1.0.0 should be considered rough drafts.

Today is a big day for me. Today I become (dramatic pause)… a published author!
I am excited to announce the launch of the Modern Web Practices ebook, a collection of six chapters on web development forged in the fiery crucibles at appendTo!

I wrote a little bash alias a while ago to help me instantly to the root directory of a git project from any directory beneath it.
It’s pretty simple. Assume
/projects/foo is the root of a project under git. Assume your pwd is
/projects/foo/bar/baz. At the prompt, typing
git-root will return you to
This works by changing pwd to be the actual
.git directory under the project root, and then backing out of it one level up (to
