  • In Australia it depends on whom you ask.

    The Greens say it’s a catastrophe.

    The Labor party says it’s a problem, but not enough of one to actively do anything about.

    The Liberal party tell you what you want to hear, but support the fossil fuel lobby while saying that it’s not manmade.

    The National party wants more nuclear power because apparently it’s “better” … for some reason that nobody understands.

    One Nation blames the immigrants

    The Trumpet of Patriots blame One Nation.

    Fringe dwellers blame COVID, or grasshoppers, or kangaroos … it’s hard to keep track.

    I’m not sure if you’re being sarcastic, observant, or something else. There have been many a meal where I was asked what I wanted to eat and it’s rare that I go beyond the words “surprise me”, knowing full well that the person asking would eat the same as I was offered, making the “surprise”, less of a risk and more of an adventure.

    In this case, OP asked a completely unanswerable question to which there was absolutely no reasonable answer, since we know nothing about the person, their interests, their experience, the hardware they have access to, or anything remotely resembling a needs analysis.

    So, even my answer, generic and random as it might appear, was based on how I use a computer, namely, to be productive. I’ve been using them for over 40 years, mostly like that, with some sojourns into art and personal expression, not nearly worthy of public scrutiny, but not specifically “productive” as such.

    So … what were you attempting to say?




  • I’ve been using Linux for over a quarter of a century. Initially I spent hours attempting to come up with the best partitioning scheme but these days I pick LVM and use the defaults.

    If I run out of space, I add a drive (or grow the virtual one) and grow the filesystem into the extra space.

    Sometimes I need temporary space and use sshfs to mount a directory from another machine.

    In other words, today you have infinite options to adjust according to need, partition schemes are not nearly as important.

    Even swap space can live as a file on a normal partition if required.

    That said. If you have specific use cases, check what’s required. Specifically because different uses need different attributes, it pays to check.



  • 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.
