  • Larry Niven’s “Known Space” has quite a few machines, but they’re generally not the point of the story. There’s a lot more about how human and non-human species relate and interact, and how the machines affect their behaviour and choices.

    The whole approach of Puppeteers (technically brilliant cowards) and Kzinti (foolishly rash but honourable risk-takers), taken against human approaches is well-written.

    Of course, once you comprehend its size, the Ringworld itself overwhelms a lot of the rest of the stories 😲.

    Niven’s attitude to women and sex haven’t aged well…

    But the stories are pretty good. He knows how to set multiple threads on their way and bind them up together at the end, or at least leave a decent cliff-hanger for a sequel.








  • We’re in a bushfire zone, even had one get close, late last year. We looked into suppression systems, and there’s two types - one has a series of garden sprinklers positioned on your roof gutters or overhangs. They get turned on to create a large, extended fan-type spray of water. The idea is not to extinguish a fire, but to absorb the heat so it doesn’t get hot enough locally to ignite your house.

    The other type - which we chose - puts agricultural sprinkler heads on your roof peaks. Fed by a substantial pump from storage tanks ( 2 x 22,500 litre/5000 gallons), they throw in intersecting circles out to a distance of about 15 metres/50 feet. The idea is to saturate your roof and walls, and surrounding foliage sufficiently that it won’t ignite.
