Intro
$ uptime is a command that returns set of values involving, the current time, and the amount of time system is in running state, number of users currently logged in, and the load time for the past 1, 5 and 15 minutes respectively (on linux the command comes with options).
Running $ uptime on your local terminal will output these values for your computer. logging into a server and running $ uptime will respond with the servers stats.
Uptime is generally used as a measure for system reliability (yes please question that).
Turning to cerealbox, I recognize it as a highly temporal server. Not only for the fact that it goes down often, it also has a determined moment of initialization (ironically also called birth) which is the start of our years program, and an equally determined life end (year 24/26 graduation).
Another layer of time is created through the servers micro-material temporality (geological history and futures).
In that sense multiple time layers connect a community that use the server, the servers own operations and its material relations.
Raspberry Pi
which model do we use?
Materials
| Material | Application
(on the raspberry pi) |
Source | Method of sourcing | Reference | Timescale
(circle) |
|---|---|---|---|---|---|
| Silicon Dioxide
(from Sand) |
Semiconductor chip (CPU + GPU)

publishing
since a servers most 'natural' way of interfacing might be the terminal, is it possible to make a publication (mainly) working in there? it could maybe still have other outlets, web or print
