22 June 2020, with some edits in December 2021. A while ago someone suggested I write a letter to my younger self. I couldn’t think what I would possibly want to say. But today, cuddling my big Appaloosa, Indigo, I thought at least I should tell younger-me that she does finally get a horse.
Zandvlei, Demogarchy and Bitcoin
in draft.
I used to be on the Zandvlei Protected Areas Advisory Committee (ZPAAC) for a few years. We were a group of people, both volunteers, residents in the area, and City employees tasked with managing the estuary, or ‘vlei’ in Afrikaans, hence the name. It was heavily impacted by poor design and construction choices in the 60s, in the form of the Marina da Gama estate, primarily, but also inappropriate urban density upstream, both formal and informal (backyard dwellers upstream with insufficient service delivery, and not enough toilets). So it needed constant management – rewilding was simply not an option.

ThisIsColossal shared this beautiful game by Oskar Stålberg which immediately reminded me of my urban metabolism game (I mention it here).

Is LaTeX worth learning?
I’ve had a bee in my bonnet about learning LaTeX (or any of its brethren like Overleaf or Lyx) for ages now. I like the markup approach, but it is not user friendly. The latex jokes are tired. And ye gods I hate that font, first thing I learnt to change. For the purpose of this post I lump the ‘prettier’ helpers like Lyx, Overleaf, TeXStudio, KILE with LaTeX. From a websearch, the most promising potential alternatives are Scribus and SILE. And there is the option to fall back on LibreOffice Writer …. So, is LaTeX worth it?
Read moreHigh temperature solar … sand bricks.
This started with a fascination with Markus Keyser’s solar sinter. After unsuccessfully trying to get a Fresnel lens cheaply, I gave up on this idea. It also just didn’t seem that easy to do; too much fiddling for a hobbyist. When I sniffed around his website some more, I got the feeling he felt the same way. Compare his more recent 3D glass printing which I think could be done by melting the sand with a solar thermal collector (more on this below), and then interestingly, when I found his thesis defence, his wider logic was particularly impressive.

I’ve been thinking about income, and what I’m willing to charge for. I’m not willing to charge for consulting, for example, and have been thinking about why.

‘Adventure Sport and Science Tourism’ was a point on my very first business card. I think I had something like the Cape Town Science Centre in Observatory in mind, coupled with orienteering and adventure racing. Now I am thinking to have a ‘Science Barn’ where one can have Virtual or Augmented Reality events, and, you know, entertaining events that educate in the fields of STEM, with the Social Science angle ala STEMS2 . My problem is that although I can rationally assert that these are all very important, I get bored with these. They are not fun or extreme enough and actually, I don’t need to conform to a curriculum or whatnot. I also don’t want to invest in things that stand there gathering dust. Better to invest in things I’d use, but that can also be opened up to the public. So this post is a reminder of the stuff I’ve come across that I’d like to try out, and maybe it can generate excitement and income on the side.
