When I hear people talk about Go, a lot of the discussions focus on its concurrency features. Whilst it has a good concurrency story, the language landscape is currently filled with languages that have an equally good or better concurrency story – F#, Erlang, Elixir, Clojure, etc… Personally, what I found really interesting from my …
DISCLAIMER : as always, you should benchmark against your payload and use case, the benchmark numbers I have produced here is unlikely to be representative of your use cases and neither is anybody else’s benchmark numbers. You can use the simple test harness I created and see these example code to benchmark against your particular …
The most common issue I have encountered in production are latency/performance related. They can be symptoms of a whole host of underlying causes ranging from AWS network issues (which can also manifest itself in latency/error-rate spikes in any of the AWS services), over-loaded servers to simple GC pauses. Latency issues are inevitable – as much …
“A language that doesn’t affect the way you think about programming, is not worth knowing.” – Alan Perlis In my last post, I outlined the techniques to learning that I picked up from Josh Kaufman’s TEDx talk. I briefly mentioned that one should learn a new paradigm rather than a language with a slightly different …

Being a responsible speaker, I have started preparing my talk – A tour of the language landscape – for NDC Oslo months ahead of time! When I first came up with the idea for this talk, I asked on Twitter if anyone else thought it was a good idea. Phil made a great point about …
This excellent book by Steve Krug was a real eye opener when I chanced upon it a few years ago. I’m not a UI/UX designer by trade or by training, and as a backend developer my appreciation for UI/UX has very little outlet in my day-to-day job either. But still I find plenty of symmetries …
A friend of mine, Roger Engelber, pointed me to a nice article on doing functional programming in Lua. The article detailed the steps to generate a flame like effects using a simple particle system. Of course, it naturally lead to me trying to do the same in Elm! To translate the approach was really …
Whilst talking with an ex-colleague, a question came up on how to implement the Stable Marriage problem using a message passing approach. Naturally, I wanted to answer that question with Erlang! Let’s first dissect the problem and decide what processes we need and how they need to interact with one another. The stable marriage problem …
I was attempting to make some changes to some fairly old code in our codebase (something I probably wrote myself…) which hasn’t been touched on for a while. Naturally, my first step is to understand what the code does, so I started by looking at the class where I need to make my changes. Perhaps …

From the first day of QCon London, I really enjoyed Kevlin Henney’s Small is Beautiful talk. Titled after E.F. Schumacher’s book (below) of the same name, the title itself should give you a pretty good idea of what to expect from this talk. I’m a big fan of Kevlin, and his “Seven Ineffective Coding …
