Bit Syntax in Erlang One of the often under-appreciated features of Erlang is its Bit Syntax for parsing and pattern matching binary data at a bit level. For instance, to pare TCP segments you can write something along the line of: The same capability can be applied to anything binary protocols, such as video encoding, …

I love this part of the year, there are great conferences happening between now and Feb, and I’m honoured to have been accepted as speaker to some of these amazing events. Code Mesh (London) Nov 4th-5th Build Stuff (Vilnius) Nov 19th-21st I’ll be talking about how we used Neo4j to model the in-game economy …
It’s been a little while since I last spent time with Elm, and since Elm 0.13 was recently announced so what better time to get my Elm hat back on and see what’s new. There’s a new-look online debugger which looks prettier than before: but more important than that, is the new Elm Reactor command …

Sure, it comes at the cost of a few CPU cycles which might mean that …
The monster trapping mechanics in Here Be Monsters is fairly straight forward: Monsters have a type and a set of stats – Strength, Speed and IQ They have a rarity value which determines the likelihood of an encounter They have a set of baits they like, which can increase the likelihood of an encounter Traps …

I saw this tweet on my timeline the other day.. which reminded me again to look at Elm and I’ve spend the last week or so getting myself immersed with this wonderful little language built around the idea of functional reactive programming. My first impressions of Elm so far have been very positive, there are …

Having spent some time this week with Elm I have seen plenty of things to make me like it, a more in-depth review of my experience with Elm so far is in the works but for now I want to talk about Elm’s record type and how it compares with F# record type which us …
Here at Gamesys social team, we’re rethinking our current approach to logging in general, from both server and client’s perspective. Having looked at many different alternatives (it was a little hard to imagine how crowded a space log aggregation and visualization is..) one of the services which we have decided to experiment with is Sentry. …

Algebraic Data Type An algebraic data type is a basically a composite type that is formed by combining other types, sometimes also referred to as “sums-and-products” data structures (don’t worries if this is too abstract for you, examples are coming). A simple example would be a composite type that represents a binary tree that has: …
