This video doesn’t start with “hello I am grady and this is practical engineering”, it’s unwatchable (also the sad / doomy music is distasteful, and so is claiming knowledge of causative factors when the incident is under active investigation).
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.)
The sockets also go up to 32 amps while being seamlessly backwards compatible with lower amperages (via keying the ground prong). https://en.wikipedia.org/wiki/AS/NZS_3112
Yeah I miss them. When we visited home last, my girlfriend (German) was amazed that we have a switch on them to turn each plug off and on rather than having to completely yank it out of the wall like with the Euro ones.
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"
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.
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.
The "projected area" theory is a common misconception of how dihedral works (that I also subscribed to for many years). All things being equal, the port and starboard wings create the the same amount of roll torque, no matter which one is 'facing' the ground better (of course, dihedral does still work, because all things are not equal).
While doing circuit training, a student pilot can do 5 training circuits of 6 mins each using 30 minutes of battery. They'll probably be so overwhelmed and fatigued afterwards (well, I was anyway) that their day's training is over. That's five or six exhausted student pilots per exhausted battery. :)
