Knowledge sharing is systems building
31 March 2023It is not uncommon to hear the parable about the blind people and the elephant when learning about systems. It’s a story about a group of blind people who have never come across an elephant before, and who learn and imagine what an elephant is by touching it. As I...

Rust, array type not generic over the size of an array type.
04 January 2019Rust You can declare and initialise a mutable array in Rust like this let mut xs : [u32; 8] = [1,2,3,4,5,6,7,8]; alternatively you could separate the initialisation like: let mut xs : [u32; 8] ; xs = [1,2,3,4,5,6,7,8]; I was surprised when I was not able to re-assign the array...
Recommended history of computing books
04 October 2018These are some great history of computing books, in this list I chose books that tend to focus on software and programming languages. These are books I like in categories I invented myself. Reference books A Science of Operations: Machines, logic and the invention of programming. - Mark Priestley. A...
TIL in Purescript
26 April 2018I am learning a little bit of [Purescript] and today I learned: Custom infix operators (unsuprisingly) don’t work on Psci (the Purescript REPL) Function application has higher precedence than all other operators ie: > show $ sumOfSquares 3 4 + 5 "30" Resources The Purescript book: Excellent book, not only...
Techdebt register
27 March 2018There is really no hard and fast rule for recording technical debt, some people do it on their bug trackers, others in their agile/kanban boards, storing it in a text file with the code is another way. The reason why this can be helpful is because technical debt can be...
Things I wish some told me when I started my computing degree
30 January 2018It has been a long time since I posted anything here. I recently had the pleasure of giving a talk at Middlesex University, for students at the start of their CS degree. It was a really nice experience. I was wondering what would be useful things for them to hear...
Initialization Error on JVM based tests
08 February 2017If you are working with intellij and gradle you might at some point hit the Initialization error : “java.lang.AssertionError: Java Assertions should be disabled!” this is becasue intellij doesn’t import this setting from gradle. To disable it go to Run -> Edit Configurations… in VM options remove -ea Removing this...
Many shapes and the same function
12 January 2017I was playing around with a small function in Scala and found it kind of interesting that you can express the same thing in different ways. We are writting a function that will fold over a string an accumulate on running parensToFloor a function that looks like: def parensToFloor(c:Char): Int...
VS Code + Ionide-FSharp
02 January 2017For the first post of the year, a short post on something I keep forgetting, hopefully it will help someone else. With Visual Studio Code, a performant fork of Atom, if you want to use F# then you are probably using Ionide-fsharp extension with Ionide-FAKE and Ionide-Paket. Some aspects of...
Michael Feathers on Types
27 April 2016WHY TYPES AREN’T VERY IMPORTANT , a talk by Michael Feathers This was a talk at the FP User group. Michael proposed that types are about ergonomics. He proposed that they are not inherently good or bad, but that it depends on the problem and the personal choice, with much...
Using Type providers
27 February 2016I wrote a little bit about type providers here but I haven’t in a while and the time has come to check them out again. The problem Let’s say that I want to use the Giphy API, which gives back data in json format including a (generally funny) gif. From...
Database of programming languages II
14 February 2016I mentioned in a post yesterday that I was looking for a programming languages database with this minimum info: Programming language name (and family if it has one .i.e. OCaml and the ML family of languages) When it first appeared (anywhere outside of someone’s mind), and when it was first...
Database of programming languages?
13 February 2016As I try to understand the history of programming languages I am building a time-line with paradigms and families of the programming languages I learn about. I can’t help but wonder why there isn’t (or perhaps maybe I can’t find) some sort of catalog with all this information, it seems...
Past and future
03 January 2016This post is a (not so short) summary of the wonderful 1972 paper entitled: “Programming Languages: History and Future” by Jean Sammet[1]. She is not only one of the first (computing science) historians but also a language creator. The paper is written in a highly enjoyable style and if you...
More Computation expressions
06 December 2015I guess I am one of those people that really enjoy this time of the year, so I had to add another post. This is a sneaky(?) second post for #FsAdvent. Ready for some more computation expressions? In the previous post I introduced a definition and parts of a computation...
Computation expressions and microphones
06 December 2015It is that time of the year, and #FsAdvent is now an event we all look forward during the happy season :D. My contribution to it is this write up about computation expressions. Why? I guess it is kind of hard to learn something if you don’t know what to...

Lambda Days and dev At Lodz
01 March 2015I spent part of the past week in Poland, I landed in Łódź (if you are not a Polish speaker, look up the pronunciation). Totally extreme friendliness. I felt right at home, maybe there is something to do with my last name :D. Thanks so much for your superb welcome,...
Type providers
22 February 2015The awesome Rachel and myself were on Mostly Erlang podcast the other day (it’s not live yet), check it out they have some very cool episodes.

Creating a vm for Haskell development
19 February 2015It has been a while since I used any flavour of Linux as a development environment (so, apologies if I am showing something really obvious). Haskell development in Windows doesn’t seem to be the default :D (Haskell Platform installs and runs super well on Win7 and 8 BTW) but trying...
What is a type system
31 December 2014Curiosity killed the cat, good thing cats have 9 lives… I don’t know you, but after using a few programming languages I have too many questions about type systems, some that come to mind: What is a type system? What is a type? Do we need a type system? When...
FSharp and games in celebration times
12 December 2014The title of this post was a bit obscure as I didn’t really know what I was going to do for this entry on the #FsAdvent Calendar Make sure you check out the previous and future entries in the series. For today, I thought we would celebrate with sound, in...
FAKE, What is it and Why you should check it out
09 December 2014I have mentioned FAKE (aka F# Make) in pretty much all the talks I have done lately, however I never explained in detail some of the key aspects of this amazing build DSL. FAKE is a build automation system with capabilities which are similar to make and rake. The DSL...
CodeMesh braindump, notes
24 November 2014I took some notes during CodeMesh a few weeks ago, and here they are. There are a few good talks that I couldn’t attend that are totally worth it, check them out when their videos become available. Last year, CodeMesh showed me a lot of what I felt I was...
Converting a small game from C# to F# part 2
30 September 2014This post could also be called:One step forward, two steps backwards. I thought I should rewind a little bit, and have an overview of the game before we continue. The C# version of the game has 9 files and each, each has a class where (generally a component is defined),...
Converting a small game from C# to F# part 1

Why F sharp and functional programming in general.
10 May 2014Why I have been learning F# (and functional programming in general) lately: It’s functional first, so it encourages you to write pure functions and other cool stuff. No more NullReferenceExceptions (wooohoo yeah! PARTY NOISES!!) Amazing type system. Think type inference on steroids and automatic generalization. Tuples: it is great to...
Behaviour trees first attempt at implementing in F sharp
05 May 2014Recently I saw a post about a simple FSM implementation in F# (link), and that got me thinking about our Behaviour Trees and how simple or complex it would be to implement them in F#. ##What are behaviour trees? There is a longer intro to the topic here and a...
F# scripting for a component based game engine
21 April 2014Recently Andrew added C# scripting capabilities to Duality, the engine we are using to build Honourbound. Once we had something working, we started thinking about the fact that it might be pretty simple to add support for [F#][fsh], so we did. A few weekends ago I twitted this: We had...

The importance of win times
10 March 2014As most developers I have really good and really bad days, it comes with the nature of the job. Lately I have been thinking that I had a lot of bad days, I needed to feel like I was wining and so I solved a small totally unrelated problem, I...
Learning F# with Katas
25 February 2014For a while, I’ve been trying to learn functional programming and after a lot of proding I chose to learn F# this year, the reasons: I though I should learn Haskell, the ideas behind the language are great. I learned a little bit, but, when I tried to build something...
Game AI pro review
12 February 2014TL;DR: It is not everyday that I definitely need to learn from a book. When I got “Game AI pro” I needed to learn as much as possible about practical usage of Behaviour Trees, and it didn’t disappoint. General Review These series of books by CRC show a high level...
CodeMesh presentation slides
24 January 2014Possibly what blew my mind the most last year was attending and presenting at CodeMesh, the conference line-up was impeccable, and of course, the interesting bits happened when talking to people there.

Yeppp!... for numbers
04 January 2014On the interwebz today I found an interesting library that somehow I haven’t heard of before, and it is a few years old, I wonder if the low popularity level is due to it’s unconventional name: [Yeppp!][yeppp] What is it? Yeppp! is a high-performance SIMD-optimized mathematical library for x86, ARM,...
MEF and AppDomains II
03 January 2014Continuing from yesterday, I was testing how hard it is to work with two domains, I found this and it seemed like a good starting place. I started moving things around to understand how it all fits together, and soon I started getting remoting errors… it made me think, I...
MEF and AppDomains
02 January 2014The last few days I’ve been playing with MEF. MEF is pretty cool, it allows you to recompose your application on the fly so I thought I should try it, I ended up looking at “The Way of MEF”, a series of samples from Glenn Block, pretty good to look...

Multithreaded game engine -Using Concurrent collections instead
22 June 2013So, while I was trying to implement the double buffer (previous post available here) I started thinking about perhaps a simpler implementation with one of the concurrent collections, so I tried with a ConcurrentQueue<T>. The idea behind it is pretty simple. Instead of having the two collections of RenderCommand we...
Multithreading rendering in a game engine with C# - Double buffer implementation
24 May 2013A game running at 60FPS needs to render every 16 milliseconds, meaning that all the logic for collision detection, animation, obstacle avoidance, physics, etc. must happen in that very short time. You also need to prepare for rendering and then send the instructions to the GPU. Multithreading see ms like...
The dying platform: .Net

More Mono for android (Xamarin.Android) little tips.
15 March 2013Mono for android or Xamarin.Android little tips: If you turn on GPU emulation, sometimes GPU emulation doesn’t actually start, it downgrades to software rendering, this makes the emulator slower and it doesn’t actually uses OpenGL(if you are using monogame, this means your game would probably not work). If you are...
