Multiple displays on a Mac sucks

So many people I’ve worked with have used multiple displays – typically a matched pair side-by-side – and sworn by them. It’s always mystified me, to be honest. I’ve attempted the multi-display lifestyle a few times over the last thirty years. At first as a bourgeois indulgence, back when even having a single 17″ display… Read more

Apple antitrust & music piracy

The position of many folks – most recently the U.S. Department of Justice – against Apple has drawn an unexpected parallel to that of music pirates in the late 90’s and early 2000’s.

The actual binary… Read more

The privileges & challenges of being a primitive type for Codable in Swift

This is an elaboration of some posts made in the discussion of SE-425: 128-bit Integer Types. I think it warrants sharing a little more broadly – not because most people ever need to care about this, but rather because it’s interesting. You might have noticed that the primitive types e.g.: …all conform to Codable (which… Read more
