I’ve mentioned in the past how you can configure the MongoDB Java driver output from Java. Most Clojure applications that use MongoDB use a database driver that wraps the official MongoDB Java driver. I personally use monger for a lot of my projects, but also occasionally created my own wrapper. The methods described in this post should be applicable to other Clojure MongoDB drivers as long as they wrap the official MongoDB Java driver. They should also work if your application directly…

I like Lispy languages. One I’ve been playing with – and occasionally been using for smaller projects – is Clojure. Clojure projects usually use Leiningen for their build system. There are generally two ways to install leiningen – just download the script as per the Leiningen web site, or use the OS package manager. I usually prefer using the OS package manager, but Manjaro doesn’t include leiningen as a package in its repositories. Installing leiningen is pretty easy via the package manager and…

Uncle Bob Martin discovered Clojure fairly recently and really, really likes it. Having had the privilege to see him speak at various SD West conferences back when they still were a thing, I wasn’t surprised by this. Anyway, do yourself a favour and spend a few minutes reading the article. It’s worth your time.

Lisp dialects like Clojure have a very rich set of algorithms that can present altered views on containers without modifying data in the underlying container. This is very important in functional languages as data is immutable and returning copies of containers is costly despite the containers being optimised for copy-on-write. Having these algorithms available prevents unnecessary data copies. While I am not going into mutating algorithms in this post, the tradition of non-modifying alghorithms…

I’ve recently been working in Clojure on some code that really benefits from parallelization but doesn’t need to squeeze the last available cycle out of the machine.
