Execution units are often pipelined
In the context of out-of-order microarchitectures, I was under the impression that execution units remain occupied until the µop they’re processing is complete. This is often not the case.

How misaligning data can increase performance 12x by reducing cache misses
Here's the graph of a toy benchmark 1 of page-aligned vs. mis-aligned accesses; it shows a ratio of performance between the two at different working set sizes. If this benchmark seems contrived, it actually comes from a real world example of the disastrous performance implications of using nice power of 2 alignment…

ReasonML: Strict, powerful and forgiving
I gave this talk at JSFoo, Bengaluru, in October 2018. It describes my experience in switching to ReasonML on the Turaku project and how learning to use a statically-typed functional programming language involves much more than learning the language's syntax or features.

Mod and remainder are not the same
A remainder and a modulus look so very similar, but they are not the same thing and worse, are treated differently by different programming languages. Do you know how your language handles mod?

Coding Machines
After a minute Patrick came back with a small dusty cardboard box. Dave and I stared as Patrick opened it and pulled out a network switch, the old kind from the days when they were made with metal cases. He plugged in the power supply and carefully straightened out a CAT -5 cable to hook the switch up to our network…
