That's it for our Wrap Up 2018 series. There were two more sections: DLT 2018 and Green 2018; the first was too meh and the second will be left for another occasion. To conclude, we have two 'random' items. The first is the video above of a pianist who, for an hour, took random requests from twitch fans to play snippets of any song, and could recall over 200+ songs from memory. The second is some random rambling below.
Random Notes on previous posts
Won't EVs simply transfer pollution to power plants?
- Petrol engines 25% efficient, coal 30% , newer coal 40%, gas turbines 60%.
- If a coal plant is upgraded to solar, EVs are automatically upgraded to solar.
- Legacy vehicles discharge at closer range, eg. near residences.
Is Tik Tok decadent and rave parties hedonistic? calendata is family friendly
- Tik Tok: kids having fun with amateur art.
- Rave parties: were giant networking events.
- Wholesome or not depends on the event and organiser.
Why Ewallets?
- Cash can be very unhygienic.
- Better visibility of expenditure.
- Cash can be faked, miscounted, dropped etc.
Why Cash?
- Need to cater for the people who do not have ewallets.
- Cash is a fall-back for ewallets (during network/power down, server crash).
- Cashless Sweden is forcing the retention of cash use, for national security.
Ewallet Use Cases
- Cash-free day once a month
- Cash-free foodcourt + e-ordering (sit, order, buzzed to collect food).
- Hygienic, save on cashier, foodcourt must be popular beforehand.
