Casual.

I’ve been on a casual, retro vibe t-shirt craze lately. Here’s the latest t-shirt to enter the paradigm. This limited run UNIX t-shirt from Cotton Bureau arrived yesterday and I am very much enjoying it.

For those not familiar with UNIX, it’s an operating system that’s been around for decades. Technically, Apple products run on a variant of UNIX, and Linux is based on the principles of UNIX. When I worked for Digital Equipment Corporation (DEC) back in the late ’80s and early ’90s, they had a variant of UNIX called Ultrix, which was frowned upon within the company because it competed with DEC’s VAX/VMS operating system.
