  • An easement is listed when you buy a property. It’s detailed on the property title, and has drawings showing where it is, and who has access.

    These new laws were the complete opposite - as long as the property was larger than 1100m^2, it was assumed to be of cultural significance until proven otherwise. The landowner needs to notify aboriginal people (whoever that is?), then they take their feedback to apply for a permit from the government, then the government will notify aboriginal people (again, who?) then based on their feedback will issue a permit (or not). And this same process would apply wether you’re fixing the retic in your suburban backyard, or digging a billion tonne open cut mining pit in the Pilbara.




  • 48V DC is the standard voltage in a bunch of industrial applications. At work I’ve installed sites with over 300kWh of storage, all at 48VDC. Back in the day it was strings of 24x 2V lead-acid batteries. Recently the industry is moving towards cells with 14x - 16x lithium cells, depending on the exact lithium chemistry.

    You need an inverter to go from DC to AC anyway, changing the voltage at the same time doesn’t add much to the complexity. Some systems use 400V, but the actually batteries those systems use are usually 8x 48V batteries connected in series.





  • The APS pay scale defines the salary of everyone working for the federal government. Your pay is determined by your level. Your level is (mostly) determined by how senior your are in the Organisational Chart, and the OrgChart basically shows how many people work under you. So the only way to earn more is to manage more people. This results in people who are highly skilled in a subject matter doing middle-management instead, because that’s what happens when you get promoted. It simply reinforces the Peter Principle, resulting in a hierarchy where no one is doing the job they are best suited to. In the APS, you can’t get to $100k without becoming a manager.

    Private companies don’t do that. If you’re very good at something, they can pay you well for it, they won’t force you to take on management just to get a raise. It means people can do what they’re best at, and you can attract and retain the best people to fill the roles you need.

    I’ve worked with engineers on $200k+ working under a supervisor on $110k, because the engineer is highly skilled in a particular technology, while the supervisor was a graduate who got their MBA a couple of years after graduating and are working their way up the corporate ladder.


  • Government departments could build up internal teams of experts. (They already have this in technical fields where then Big 4 don’t have expertise.) But government pay is crap compared to these giant corporations, so the best will be scooped up by the private sector while the less impressive employees stay employed for life in government.

    To make it work would require a different system to what the government has now. A system with merit-based remuneration and much simpler hiring-and-firing.

    (I say this as someone who originally worked for the government, then moved to the private sector.)






  • You’ll need to get a fire rated media safe, not just a fireproof safe. A regular fireproof safe will keep the internal temperature below 175C if exposed to a 30 minute wood fire - what you’d typically experience in a home fire. The 175C is to stop paper from igniting, but at that temp your HDDs would be toast.

    A data/media safe should maintain an internal temp of under 60C if exposed to the same fire. That means it needs to have much more thermal insulation, and as a consequence it will be significantly bigger and more expensive. To fit in the whole enclosure, you’ll probably have to pay more for the safe than the HDDs.
