  • Well when it hits 7 I mean they literally have no spare energy for anyone or anything else.

    The death of the petrodollar will do a lot to encourage renewables. When you don’t have the US breathing down your neck to buy oil in USD to support their empire you can buy it with whatever currency you want and decarbonize. The current world order and its financial system is what’s kept us on fossil fuels for so long. You literally couldn’t get off of them meaningfully or you would piss off the US. Any attempt to change that system was met with arrest, revolution, or death for those who suggested it.


  • Specifically I’ve heard that about the Energy Returned On Energy Invested (EROEI) which is the oil and gas industry’s equivalent to Levellized Cost Of Electricity (LCOE)

    for reference the spindle top formation in Texas (that started the oil boom and kicked industrialization into high gear) was an EROEI of 100:1. You burn a barrel of energy, get 100 barrels.

    Nowadays things are far more bleak… Our average EROEI is around 12-14 as a global average. Tar sands is 2-4. Shale oil (fracking) isn’t much better at around 4-6, sometimes less.

    As an aside on why fracking is so low: you put a loooot of energy into drilling and banging, and then you lose 70% of your flow after a year. 2 years after drilling the well is dead and you need to do it all over again.

    A lot of economists (and other experts) have placed a point of no return for the world economy around an EROEI of 7, which we should reach in roughly 10-15 years.

    Once energy returns get that low the oil industry exists to support the oil industry. There isn’t enough surplus energy to run a complex globalized nation. It’s a bit like starvation when all we’ve known is a surplus of calories for 200 years.



  • Honestly it’s a result of being the world’s reserve currency. At one point Brazil was the capital of rubber, and like 2 towns in Brazil made all of the latex the world used. They used to ship their clothing to Europe to be washed. Then 900 rubber tree seeds were smuggled out and it crashed their monopoly, devastating those towns.

    Much the same has happened to the US when you can deindustrialize and print without consequences. The same happened to Spain with their silver mines in the age of sail. Silver flowed through Spain, but didn’t stay there… It was cheaper to buy foreign goods in Spanish silver than to pay a Spaniard to do it. When the silver ran out it all crumbled…

    Trump killed the petrodollar and it’s going to turn the US into an inward looking regional power…


  • Kinda? it depends. Basically all modern CPUs have compression hardware acceleration or idle cores, though so sometimes disk compression can have little to no impact on your OS’ speed but increase the bandwidth of your drive by a lot. Hard drives and SSDs are half simplex, so reducing nuisance reads by 10% can make your drive appear faster at both reads and writes.

    As an aside, this is why I like ZFS so much. Part of what makes ZFS great is the ARC cache with smart eviction. Most Frequently/Recently Used (MFU/MRU) allows for repeated reads from the same info to come from RAM and not a slow pool. It opens up all of that available bandwidth and IOPs for writes if you need too, or for aggressive prefetching.

    Grandpa’s strongest potion:

    10 lbs of sugar

    As many crab apples as you can get from your grandpas crab apple tree

    Juice them all

    Mix juice with sugar in sanitized fermentation bucket (use starsan) and add enough boiling water to get up to 10% ABV on your gauge.

    Rehydrate yeast in a lukewarm dilute sugar solution so you don’t shock it.

    Add to mash and seal with airlock

    Ferment until there’s no change in specific gravity between days

    Rack your wash off of the Lee’s into a different jug and start distilling it with a water distillation still.

    Once you have a first pass done, distill it again and toss the foreshot this time.

    Stop distilling when the alcohol content drops below about 48% or when it tastes horrible.

    Typically you end up with 68-80% ABV potion. Grandpa’s strongest potion also gives grandpa strongest hangover, so watch out.
