Auch sehr schön: WTF Util

WTF is a personal information dashboard for your terminal, developed for those who spend most of their day in the command line. […] Keep an eye on your OpsGenie schedules, Google Calendar, Git and GitHub repositories, and New Relic deployments. See who’s away in BambooHR, which Jira tickets are assigned to you, and what time it is in Barcelona. It even has weather. And clocks. And emoji.

Danke, Martin!
