Exploring the .NET Core Runtime
It seems like this time of year anyone with a blog is doing some sort of ‘advent calendar’, i.e. 24 posts leading up to Christmas. For instance there’s a F# one which inspired a C# one (C# copying from F#, that never happens 😉)

Reverse-Engineering Xkcd's 'Frequency'
About a week ago, Randall Munroe published Frequency , the 1331st entry in his xkcd webcomic series. Unlike most xkcd comics, it's animated — actually, 5-by-10 grid of animated GIFs. Each describes a scenario (e.g., "one birth," or "someone locks their keys in their care") and blinks at the scenario's purported…

Pain Points of Haskell
I would like to preface this article by saying that Haskell is great. I have been using it as my go-to for native applications for several years now. Everything that follows is a product of my love and affection for the language, and a desire to see it succeed. And none of this is intended to disparage the efforts of…

Master of Orion
Given the shadow which the original Master of Orion still casts over the gaming landscape of today, one might be forgiven for assuming, as many younger gamers doubtless do, that it was the very first conquer-the-galaxy grand-strategy game ever made.

But as time progressed—especially after completing a…

When Haskell Is Not faster than C
This article is in response to an earlier one comparing Haskell and C, which made the claim that Haskell beats out C when it comes to speed. On a Hacker News thread I made the bold claim that the C code is rife with problems and that it is tempting to fix it.
