After nearly a decade of building embedded systems in C, C++, and Rust, I’ve somehow ended up writing Haskell for a living. If you’d asked me about functional programming a few years ago, I would have told you it was self-indulgent academic baloney—and then I stumbled into people using it for real-time systems where microseconds can mean literal life or death. I’m too old to try to convince people what tools they should use, but Haskell has some features that might interest anyone who cares abo

Introduction One of the key insights from queuing theory is that the average queue size for an unbounded system tends to increase significantly as utilization approaches 100%. Theoretical models show no bound to this increase and at 100% utilization the resulting average queue size grows toward infinity. This is important because queues themselves consume resources, be it memory or disk space on a computer or factory floor space in a plant. In an ideal world, we wouldn’t need queues. Who likes

Recently I encountered a bug so cute that I immediately knew that I will want to share it on my blog. It was one of those bugs that even Rust can’t save you from. It occurred in HyperQueue (HQ), a distributed task scheduler written in Rust that I work on. Despite the fact that HyperQueue is a pretty non-trivial distributed application, and it has long been developed mostly only by two people that only have a limited time available for it, it has so far been very reliable, which always fascinate

Suppose we have a list of items of length \(n\), and we want to consider windows (i.e. contiguous subsequences) of width \(w\) within the list. ⊕ A list of numbers, with contiguous size-3 windows highlighted We can compute the sum of each window by brute force in \(O(nw)\) time, by simply generating the list of all the windows and then summing each. But, of course, we can do better: keep track of the sum of the current window; every time we slide the window one element to the right we can
