Australian plugs are the best I've used for the following reasons (amongst others, mostly mentioned in TFA): two and three-pin (earthed) use the same socket; irreversible (even the 2-pin plug is polarized); the flat pins allow a larger plug/socket contact area for current; small size; partially insulated power-pins stop shorts if stray conductors fall on partially-plugged in plugs.
(I'm not Australian and don't live there.)
It's a tool to install (in one line) and manage reverse SSH tunnels for access to my geographically dispersed, outdoor Raspberry Pis (that are contributing to various aeroplane position reporting systems, my most relevant being Open Glider Network e.g. https://www.gliderradar.com/center/39.16414,-12.65625/zoom/3 ).
I've actually found the output faster to parse if it's all in consistent units (megabytes [-m]). Also find adding a grand total [-c] and staying on one filesystem [-x] useful. I.e. in ~/.bashrc:
alias dua="du -cmx --max-depth=1"
alias duas="du -cmx --max-depth=1 | sort -g"
I did not know about Amazon GameLift. I guess I just used the word "fleet" to mean "a collection of similar things under unified control". (Unified control being the aim of the project.) In this case, as building block, I'm using robust, persistent reverse SSH tunnels.
It evolved to scratch my own itch: simplifying the access, management, and monitoring of a fleet of distributed Raspberry Pis (running Raspbian, on private networks) without requiring any proprietary client-side code.
Though it meets the submitter's criteria, it's not [yet] providing enough to live off.
