Link: A Child’s Garden of Inter-Service Authentication Schemes
A Child’s Garden of Inter-Service Authentication Schemes is an opinionated overview of service to service authentication schemes from Latacora (via, which has comments worth reading for once, including from various Latacora people). As with pretty much everything Latacora writes on their blog, it's not just informative, it's entertaining too. I find it well worth reading.
(Latacora people include Thomas Ptacek, who you may remember from Against DNSSEC.)
Link: About the memory management in the Bourne shell
About the memory management in the Bourne shell (via) is a collection of discussions about the original Bourne shell's creative, interesting, and infamous approach to memory management in the original Unix memory allocation scheme. If you like this kind of thing, it's worth reading through and decoding things.
(It also links to a recording of Stephen Bourne's BSDCan 2015 talk "Early days of Unix and design of sh", which I haven't watched yet but keep seeing links to. Someday.)
