Introducing Chronos: A Replacement for Cron
A distributed, fault-tolerant "cron" is something which comes up frequently -- it makes for a great fault-tolerance building block. This one sounds like it's too closely tied into Mesos, though (IMO).
Chronos is our replacement for cron. It is a distributed and fault-tolerant scheduler which runs on top of Mesos. It's a framework and supports custom mesos executors as well as the default command executor. Thus by default, Chronos executes SH (on most systems BASH) scripts. Chronos can be used to interact with systems such as Hadoop (incl. EMR), even if the mesos slaves on which execution happens do not have Hadoop installed. Included wrapper scripts allow transfering files and executing them on a remote machine in the background and using asynchroneous callbacks to notify Chronos of job completion or failures.

BBC News - Sentinel project research reveals UK GPS jammer use
GPS jamming was this commonplace? I had no idea. '"We believe there's between 50 and 450 occurrences in the UK every day," said Charles Curry of Chronos Technology, the company leading the project, though he stressed that they were still analysing the data.' [...] "Most of them are used by people who don't want their vehicles to be tracked." (via Tim Bunce)
