  • There is research that shows that white coloured roofing causes increased heating elsewhere, so it’s not a fix-all solution.

    I live in Australia and during summer use a lawn sprinkler on the roof. Using a tap timer, it runs for 10 to 30 seconds every 10 minutes.

    Just enough to wet the roof, so that the water evaporates and cools it down.

    Other things you can do is growing creeper vines over a wall where the sun hits in the afternoon to keep direct sunlight off the wall.

    If you have sash windows, you can open it at the top and bottom, creating a thermal airflow that will cool the house.

    Adding sunshades and building housing with awnings makes a massive difference.

    Lots of research associated with passive solar temperature regulation.


  • Anything that has a physical location or relationship can be mapped.

    If you can find existing datasets you can add those to the map without needing to manually collect the data.

    You can also consider things like floodplains, historical flooding records, traffic flows and anything else will a geographical bent.

    This will never be finished because things are always in flux.

    One thing that you should consider is what maintenance looks like. Keep track of where datasets came from and when you retrieved them. Some countries, regions and municipalities maintain public data that you might be able to use. Make sure you comply with any licences attached to the data.

    You can also use things like the local cadastre which tracks land and building boundaries and ownership.













  • You’re welcome.

    I understand that being able to write software and be deliberate about accounting gives you a closer relationship with your financial situation.

    For me the issue is that there are no guardrails around the plaintext accounting model, which means that you have the freedom to shoot yourself in the foot.

    My current accounting software as rubbish as it is, stops me from making stupid mistakes, credits instead of debits for example. Plaintext accounting won’t.

    So either you need to never make a mistake, or have a way to figure it out.

    All that kind of safety net doesn’t exist. You can still make the books balance, but at some point you’re going to find a hole and spend weeks fixing it, or the taxman will and you’ll be paying a fine.

    I exported the line items from my current software into plaintext accounting, even made it balance and match my actual accounts.

    Then I needed to write an invoice and had to make my own, from scratch and manually enter the data twice, once into the invoice, another into plaintext accounting, giving me the chance to make an error twice, perhaps even a different one on either process. And that’s just one invoice.

    I have considered writing my own accounting software from scratch, or forking something, but that’s not going to pay for food, so I kept looking instead.

    It’s not a great place to be, either from a business perspective, or a mental one, but that’s where I’m at.
