No-frills secret sharing with openssl

Motivation Sometimes we need to share a secret with a colleague, and frequently it’s a hassle to do so securely. Worst options include people simply sending plain-text secrets over email or slack.

PostgreSQL Fatal – semctl crash and user id

Recently spent over a week in total (maybe 2 days net time) to realize that I was hitting this postgres bug – https://bugs.launchpad.net/ubuntu/+source/postgresql-9.5/+bug/1649877 .
