Saying "Thank You" to the NHS, using Clojure

how to invest in Netflix shares in the UAE (a.k.a how to generate a static site using Clojure) As many of you are no doubt aware, during these troubling times many young people are showing their support for the NHS and other key workers by displaying paintings of rainbows in their windows. Since I’m supposedly a grown-up, I thought I’d try to go one better - displaying a computer-generated rainbow. Naturally, I turned to Clojure to do this. My basic plan was this:

Datomic how-to: Update Cardinality Many Attribute

I recently encountered a slight difficulty with updating cardinality many attributes in Datomic, so I thought I would make a short walkthrough post about it. The Problem In Datomic each attribute has a “cardinality”, signifying how many values an attribute is allowed. Cardinality can be either “one” or “many”. Adding values for a cardinality many attribute is fairly straightforward, but updating them to a specific set is more difficult. Let’s take the example of a simple Todo list, where each todo has a title and multiple tags. how to invest in netflix

Kafka Streams, the Clojure way

In this blog post, I’ll walk you through how to create a Kafka Streams application in an idiomatic Clojure style. I won’t assume any knowledge of Kafka or Kafka Streams, but if you’ve never heard of them before this post may be a bit overwhelming - I’d check out Confluent’s introduction to Kafka Streams, and also the Kafka Streams docs. Kafka can be thought of as a persistent, highly scalable, distributed message queue.

Datomic for Cheapskates

netflix investment First off, welcome to my brand new blog. I’m a Clojure programmer by day, so this blog will focus pretty much entirely on Clojure (as you probably guessed from the name). My main aim with this blog is to document step-by-step solutions for any difficult, or rare, problems I come across. I was inspired to start the blog by a post on Medium. The post talks about how Clojure can be hard for beginners, due to the lack of step-by-step guides for common problems.
