If you filled in a form at the link provided from one of the bits of paper in the box they would have sent you a Chromebook for the sleeve. I'e got one here gathering dust. My boss threw away the same package but I was curious and looked through it carefully.
Did you consider using periodic calls to keep the Lambda@Edge functions "warm"? I've been playing with Zappa (https://www.zappa.io) for standard Lambda and it sets this up by default.
I think New Zealand is the same as Australia with 5 wires: the 3 phases, neutral (the central return wire) and earth. Grabbing a random location in Auckland off Street View shows 5 wires:
That just seems odd to me to have a wire for earth... carried above the earth. I can understand having earth wires in houses made of concrete and wood since they have to get to the earth through those materials, but what makes a common earth ground better than just lots of many grounding points? All that wire has got to get expensive.
The point of an earth ground is to dissipate the accumulation of static built up. Ground is not connected to the power supply so there is nothing to return to the power company. The earth is the best place for it.
That's a higher voltage power line (in the low kV range) with just the three phases. They're relying on the load being approximately distributed between the three in the downstream distribution network to obviate the need for any return wire. If you move forward one step on that road you will see the next pole has a lower set of wires which will be at 230/240 volts. On these it looks like there are four wires, they're probably doing without the earth wire in this rural area and just tying to earth periodically.
Not so much bushfires damaging electrical infrastructure as electrical infrastructure starting fires. A large portion of Victoria's worst day of bushfire was sparked by a faulty power line and the electricity distribution network (22kV and below) is responsible for a good portion of fire starts, especially those lines that utilise a single wire with an earth return (SWER). The recommendations of the Royal Commission into the Black Saturday fires in regard to the electricity network are available at http://royalcommission.vic.gov.au/Commission-Reports/Final-R... and contain a whole lot of background information. Suffice to say that the recommendation (27) of the wholesale burying of thousands of kilometres of SWER line at the cost of billions of dollars haven't gone far.
Unlikely, Kodachrome larger than 35mm was dead after the mid 1950's, there was a brief revival of medium format in the 1980's, but it didn't last long. I suspect the format might be more driven by the format of the book.
