Update: Voting is live! Vote for my app at https://clojurecup.com/#/apps/booker, then
check out some more deserving entries at https://clojurecup.com/#/apps and vote for them too!
I've just spent about 30 hours this weekend coding up Booker,
my entry to the 2014 Clojure Cup, in which I participated as a one-man team. It was pretty
exhausting, and the app doesn't do quite as much as I was hoping it might, but I'm
still quite happy with how it all turned out. Here's how my weekend went.

Clojure has an approachability problem. In part, this is due to the
relatively unusual syntax, but that can't get all the credit.
When it comes to building server-side web applications, a
major sticking point is the “lack of frameworks” problem, and
more to the point, the common Clojurian's response:
“Clojure users prefer to assemble their own stack from small, composable libraries.”

So you wrote an app. Great! Next step is to put it somewhere
where people can use it. This tutorial will walk you through
the process of deploying your app.

Problem: You need to extends some Java interface or class to use
some Java API, and for some reason Clojure's java interop tools are
too unwieldy to do it cleanly.

I saw this post by Grasswire
today, and I couldn't resist the urge to throw down a Fizz-Buzz-pocalypse.
So, here's my implementation in Clojure, along with a list of ways that Clojure
clearly wins. (That last sentence was to be read tongue-in-cheek, Scala is a good language too. Besties!).

I recently had occasion to test out using Parquet
with protobufs. I got
some simple tests working, and since I had to do a lot of reading
to get to this point, I thought I'd do the world a favor and document
the process here.

I recently stumbled across a neat library called Flambo.
Flambo is a clojure wrapper for Spark, and it does a really
great job keeping everything nice and Clojure-y. I wanted
to show you so you can enjoy it too!

Hello sir. I'm here to talk to you today about accepting Clojure into your workflow.
Do you have a few minutes? I'd like to show you these ten ways that Clojure can
help you make better software. Good, here we go!

In May, I left Canada to do some long-term travelling with my wife. I don't mention
it here because this isn't tumblr, but it does mean that I have some problems many
people don't, such as figuring out when I can return in the Schengen Area.
This is a problem that has been solved, but I've yet to see it solved well, so I

It's that time of year again! Today, we'll look at just over a half-year's worth of Github
data to draw unsubstantiated conclusions about the relative popularity of programming languages.
Ok let's go!

For the past few years, most of my posts have been beginner-intermediate
essays on various clojure features and coding techniques. Since a lot of
people have told me that they like my blog as a genre piece, I decided to
pull some of my favorites into one place, and order them by difficulty, from
Clojure beginner on up so that folks don't have to root around.

It's been about two years since I undertook my first sizable application in Clojure,
and really my first experience architecting a system in a functional language.
It was a local dating application, and it's still up and running, despite the sins
below. But, reading the code now, a few dire instances of truely bad code emerge.
So, I crawled through for some examples, which I now impart to you:

After my last post on using Clojure's STM as a quick-and-dirty in-memory datastore,
I had an interesting discussion in the comments about
the wiseness of implementing my example with a static global. Coincidentally, I attended
a talk by Stuart Sierra at EuroClojure about this very thing,
and started getting some ideas about how to make things better, which I want to share today.

I was searching for a good example to illustrate some properties of
refactoring object-oriented code into a more functional style, and
I came across this example from Martin Fowler's Refactoring.
It describes the process of refactoring code for a video store.
It's a nice little example with a useful narrative to go along with it.

I saw this post, “Do It Yourself NoSql”,
recently, and it reminded me of something that Clojure does very very well.
Clojure's go-to concurrency enabler is its
I've written about it before, but this seemed like
an opportunity to provide a nice example, and discuss a little more about some of the things
I often do to defer the need for a database.

This post is a follow-up/supplement to my article
Anatomy of a Web App: How I Built RedditLater in Clojure,
published on sitepoint.
To make the article appealing
for a mass-market audience, I had to take out most of the nitty-gritty details
that wouldn't interest people who weren't interested in Clojure to begin with (plebians!).
The details still have some good stuff in them, though, so I've made this post out of it.
So I hope you're here to read about my fiddly minutae, because off we go!

I often see arguments about whether or not using coffeescript is a good idea.
Arguments against usually center around whether it's a barrier for contributions, or
whether it's an unnecessary abstraction over another language that the developer needs
to know anyhow.

I've recently done some work with Elasticsearch. It's a great platform, but
I still found it pretty hard to get started. It wasn't obvious what was what.
Perhaps I didn't read the docs closely enough. Anyhow, I wrote up some examples
demonstrating how to get started with Elasticsearch.

Flask isn't new, but it's really great, and it's
definitely my first choice when starting a new Python app. Today I want to
give you a quick tour of the tools I use to set up a new Flask app.

Recently, I've seen popular articles on macros and metaprogramming in
Elixir. Both of these
are wonderful metaprogramming systems, to be sure, but I couldn't help
