tests
can be found on cerealbox timekeeping-device/
terminal
- ping
- to graph (graphic) visualizing length of seconds
- traceroute
- time (cmd)
ideas
- server time
- expand on cerealbox uptime, make more small api's and interfaces for them
- not so much making a clock for cerealbox but more about exploring/ surfacing its (ways of passing, keeping) time
- this is also on labour, questions of service, maintenance
- in the room are also expectations: for services to run smoothly, total availability, fast (and direct) delivery
- how do we interface with server (time) ?
- text as timekeeping device User:Sevgi
- in what ways? (we use texts, rhymes, phrases to map time periods and rhythm – text can age – a log) ...

$ ps (or $ ps aux)
outputs information on run processes (aux is more specific, shows user associated with each process, the start time, the memory consumption, the total running time, command associated with each process)
$ ps aux | wc -l
outputs a number (179). for a nicely formatted output do:
$ echo "User $USER has a total of $(ps -e | wc -l) processes running on $HOSTNAME."
last reboot
$ last reboot
