I'm in Perth. Our feed in tariff changed in July to 10c/kWh between 3pm and 9pm, and 2.5c/kWh at other times. Use tariff is 26.2c/kWh. I'm pretty sure our solar will pay itself back in under 5 years, but we have a 25 year warranty on the panels.
My parents are building outside of Adelaide and they've decided to go off grid (solar + battery + backup generator). Their expected payback period is (iirc) 8 years, with a 10 year warranty on the batteries and a 25 year warranty on the panels. They're expecting to have to run the generator once a year or so.
Dunno if your geographic size argument holds much water. Australia is about the same size as the continental US, but we always get lumped in as one entity. Canada appears to get the same treatment.
The transaction price does not reflect the true cost of the energy, nor does it reflect the negative externalities. When ~1/3 of BTC mining is powered by coal in Xinjiang, it's horrific for climate change (source: https://fortune.com/2021/04/20/bitcoin-mining-coal-china-env...). The power is cheap, in part because it does not include the externalities of the extreme CO2 emissions used to generate it.
>i don't place a utility judgement on the use of energy.
Attitudes like this are why staying under 2C of global warming is going to be a long shot at best.
>If somebody is willing to pay for their use of electricity, they deserve to use it.
A nice idea, but energy use affects us all. More fossil fuel burnt = more extreme climate change. For where I live, it means cyclones will hit land further away from the equator (and closer to larger population centres), overall rainfall will drop and bushfires will be more severe and frequent.
I feel justified in denigrating BTC because its colossal waste of power is a significant contribution to climate change. This has tangible harms to everyone on this planet.
It's absurd. repeating what I said elsewhere - my desktop at home has a 650W PSU. It would take ~76 days of full power for that to consume as much energy as a single BTC transaction.
>The problem with people claiming mining btc is a waste
It takes ~1.2 MWh to confirm a single transaction right now. My fridge at home consumes approx 300 kWh/year. Are you saying that a single BTC transaction verification provides anywhere near the utility as refrigerating food for four years?
Even comparing it to gaming, my desktop at home has a 650W PSU. It would take ~76 days of full power for that to consume as much energy as a single BTC transaction. There's orders of magnitude more energy being used by BTC, but I don't think there's orders of magnitude more benefits.
>but why can't they equivalently claim that mining bitcoins would derive enjoyment?
Bitcoin mining is a colossal waste of energy (given it's at about 1.2MWh currently to confirm a single transaction, and that number is basically nondecreasing). People playing video games are at least deriving some enjoyment from it. There are less wasteful methods of exchange than BTC.
>Please support this with data. It doesn't literally burn for it; fires are down, what, 90% from a century ago?
Got a source for the "fires are down 90%" statistic?
I think it's pretty clear that GP was referring to climate change, which wastes of energy like NFTs and BTC exacerbate. A side note - climate change means that bushfires are more common and their severity is worse than in the past. I don't think it's a stretch at all to say that the world burns for it.
Labour theory of value contends that the value of an object depends on the "congealed human labour" in that object (e.g. a chair is worth more than its constituent timber because the chair requires you exert additional labour on that timber).
Intrinsic theory of value says that some objects have some objective value, inherent in the object (or as a property of that object, like mass).
Subjective theory of value basically says "value is in the eye of the beholder".
There is also exchange theory of value, which is similar to subjective value. An object has a value decided by what it can be exchanged with (e.g. 2 square metres of linen might be worth the same as 1 coat, even though the coat only has 1 square metre of linen in it)
While Rowling provided the creative input to her stories, they were:
- Edited by other people
- Printed by other people
- (Films were) directed by other people
- Characters in the films were played by other people
- Distributed by other people
If there was no J.K. Rowling, we (admittedly) wouldn't have the stories. But the same is true of all of the other moving parts in the media business.
>I guess the hardware / IoT use case is pretty small
OSIsoft was bought earlier this year by AVEVA for $5 billion[1]. OSIsoft's offering is centered around storing industrial control system data (the buzzword-version is IIoT, though that is a bit more broad). They're also not the only player in this space. Many of the industrial automation vendors also have their own offerings.
The other surprising factor is that a lot of heavy industry will have data going back decades. If they can't get all of that data in to timestream, that's a massive mark against it.
I'd heard that it was initially developed for a major industrial operator (sounded like it was in the resources industry though I never found out who it was for), so the lack of support for late arriving data is a big surprise. That being said, there aren't any of those companies on the customers page - maybe it was just an incorrect rumour.
>If you expect a 12 hour outage, you should probably spec for 12 hours.
Industrial facilities don't always expect their outages.
> Additionally, you can scale the memory retention policy up and down as you see fit. So if you notice a network outage, you can scale up the retention policy for the duration and then reduce it back down again after.
Sure, but if you configure your database for, lets say, 4 hours of in-memory, and you have a network outage of 12 hours (this is not uncommon on mine sites), you lose 8h of data and cannot put it in to your "master store".
