I've often wondered why a service doesn't exist that allows you to rent out your graphics card for the large data processing needed for training models. Like mining bitcoin except you are doing something actually useful and getting paid actual money for it. Example:

- Company Alpha needs $40,000,000 worth of cloud computing for their training model
- Company Beta provides them said cloud computing for $30,000,000 from their pool of connected graphics cards
- Individuals can connect their computers to the Company Beta network and receive compensation for doing so. In total $20,000,000 is distributed.

Company Alpha gets their cloud computing done for cheap, Company Beta pockets the $10,000,000 difference for running a network, the individuals make money with their graphics cards, except this time it's actual United States Dollars. What am I missing here that would make this type of business unfeasible?
> I still have the electric heaters installed in my living room - they haven't been used a single time since 2010. As they're permanent installations I haven't got them removed, or I would have.
That sounds great. And sorry if I go off topic but I'm curious how you "distribute" the heat throughout the house. Air vents? Underfloor heating? If you kept the old radiators I assume you picked an option that caused the least disturbance in the home yet is still efficient enough that you didn't need extra heating in a decade.
> Point to a specific calculation where 38.5% double counting.

The calculation you did. It uses this figure, but the figure itself is already accounted for in what you were trying to model, that is what double counting is.

The annual 38.5% includes both very windy days, and very sunny days, in which consequently PV input and wind power input were very high, as well as the dark and cold but still days in which neither produces very much power.

But the problem scenario we care about is long dark cold days of winter. You can't use a figure which averages in a bright but gusty June morning and use that as representative of a miserable January, you need to look at what it's like on such days, and it's much higher than 38.5%.

Remember, your original thesis is that somehow not using gas in June will save you needing gas in January and I've shown why that's nonsense, the "stockpile" involved is just far too small for this to make any sense.

For what you wanted to do to actually make sense the UK would need to buy at least ten times as much storage as it has now, ie enough to last out a nasty winter. But it shows no sign of wanting to do that, if anything exactly the opposite, preferring to "leave it to the market" and then acting confused when the market does what you'd expect, ie gouge them for every penny it can.

That depends on how much the HVAC costs... I saw some videos from last USA freeze where people had ice (!) inside of their homes - I doubt heating that is in any way economical.

> I dont understand how heat output from a heat pump vs heat output from a gas / oil / wood burner / resistive heater are at all different.

A gas/oil/wood burner are not 100% efficient in creating heat, and release carbon into the atmosphere.

A resistive heat is at most 100% efficient: all the electrons go to making the coil glow, like old school light bulbs. So 1 kW of electricity is 1 kW of heat (which has some BTU equivalent for old fashioned folks).

A heat pump does not create heat, but moves it from one place to another with refrigerant and pumps. So 1 kW of electrical usage can move 3 kW of heat at times:

* https://en.wikipedia.org/wiki/Coefficient_of_performance

* https://energyeducation.ca/encyclopedia/Coefficient_of_perfo...

So if you input 1 kW of energy, do you want 0.9 kW of heat out (carbon), 1 kW of heat out (resistive), or >2 kW of heat out?

The idea to moving everything to heat pumps right now isn't so that you immediately reduce carbon emissions, but that everything works off of electricity and the grid so that as offshore wind, onshore wind, solar and Hinkley Point C come online it can start to replace fossil fuel energy. Same with EVs.

If you stick with gas boilers there is really no exit strategy for getting off fossil fuels.
Agree in spirit but I think companies actually need to be extremely competent and consumer/privacy focused to ensure data collected NEVER leave their testing environment.

> When an engineer like this proposes something that adds unnecessary complexity, it's usually hard to argue with. The proposed change typically does indeed make the system objectively better, and they're the one taking responsibility for doing the work and ensuring its correctness.

Flatter their egos while pointing out that they're optimizing for the wrong goal. Their objective is write something that works and can be understood, managed and extended by someone dumber or less careful than they are. That will rule out some changes entirely, but if they're really smart, that can also spur them to change their designs so they still objectively improve the system while retaining clarity.

The robot vacuums are going to be invented, going to be sold, and going to be used, regardless of whether we fix the system.

Getting snarky with people because they are upset about a much smaller, more recent, and more visible change than our gradual slide into late-stage capitalism—and one that might actually be fixable without a complete overhaul of our society and culture—is deeply unhelpful. It's the very picture of letting the perfect be the enemy of the good.

You and these people are on the same side, so maybe try showing sympathy and compassion for their frustrations, rather than mocking them for not solely and full-throatedly advocating for an overthrow of the system.
To be clear: "zero heat gain" isn't the right threshold to think about unless your house is a closed thermodynamic system. Real houses lose heat in proportion to the temperature delta between inside and outside air. So what you really want to know is the temperature at which the heat pump is no longer capable of maintaining that delta. That's a whole lot higher than -20C.

FWIW: we installed a heat pump recently here in Portland, and conveniently had a once-in-a-decade cold snap (17-20F for 3 days -- the PNW isn't that cold) in its second month. The system was just-barely-heat-flow-positive. A six hour power outage dropped the house temperature to ~64F, and it took a good 30 hours to get back to the 69F set point of the thermostat.

So... on the whole we're pleased and the system did just fine in extremis. But no way would it handle -20C/-4F.

We are going to hear about “recession” fears from the corporations who continue raising prices by 6%
1. There are things like “shrink-flation” not captured. I’ve noticed most packaged goods have reduced in size 10-20%. Eggs have more than doubled, milk is up 25%, etc

I don’t care what the government publishes. My friends around the country all confirm this. My own bills (I track itemized) show it as well. Though, to your point, much of the increase occurred in 2021 - it just never came down.

2. Fuel is only down because the US has used its strategic reserve to increase supply. At the same time demand dropped dramatically, with China lockdowns & increased prices forcing manufacturing / transportation to cease. Now the election season is over I suspect the strategic reserve will stop being drained; further if price caps work on Russia… we will see a massive reduction in the global fuel supply (Russia will just stop pumping as its unprofitable).
I like point 1, but point 2 sounds like a nightmare.

Ask HN: Services that should offer legacy management but don’t
Hey there everyone,

We recently launched Posterity Automations[1] as a way to trigger tasks in the event of death and if we can manually verify it.

We're trying to prioritize partnerships and integrations that people care the about, roughly around two important end goals:

1. Expedite access to any funds or financial accounts by your loved ones;
2. Protect privacy, by deleting or transferring accounts to the person of your choice.

Curious if there are any services you use that you feel like should have a legacy management options, but currently don’t.

If you’re the operator of a service for consumers or small businesses, we’d love to hear from you as well, as we’re thinking about offering a simple API to handle it end-to-end.

Company Alpha will probably just call up AWS or Azure and sleep easy. Company Beta can't really compete because they have to pay both themselves and their contributors; AWS could sell ML compute at-cost and still turn a profit.

What made this type of business feasible/attractive for cryptocurrency is that the miners were Company Beta. There wasn't two mouths to feed or two pockets to line, just a direct and transparent reward scheme for people donating compute. Projects like Folding@Home have leveraged world-scale networks before, but I'm not aware of anyone who's managed to monetize it.

As for code style, don't most SCCS systems now give you the option to normalize the style upon checkin?
In theory I'd agree that you should insulate first. But as others have pointed out, on some older houses, insulation can be difficult to accomplish (especially true in non-wood-framed housing). In such cases it is still a better idea to use LESS energy (because of a COP above 1) to heat that space than it is to use resistive or combustion methods (which have a COP less than 1).

No, that's about the capacity of the heating system at -20, not efficiency. It does mean that the system will be oversized for the days it doesn't get that cold.
Luckily, this does not matter for most tools -- for "grep", ASCII 46 is nether decimal point nor full-stop, it is "match any" character. "sort" is commonly used with non-number data (filenames, ISO dates) or with integer values (file sizes), and most uses of "find" can avoid floating point entirely (use -mmin instead of-mtime). And since both "expr" and bash's "$((...))" don't work on non-integer data, there is a great incentive to avoid floating point in shell scripts.

And yes, sometimes you have no choice but to care about locales, maybe you are pulling data from badly designed API or parsing files generated by someone who didn't know about "stat -c" and did "ls -l" instead. But I'd argue that in this case you should be explicit about setting locale env, and you shouldn't rely on system settings. It's not like an API will suddenly start returning different data if you move your fetching script to a machine with a different locale.
Just be honest that crypto was about evading regulations and then about getting rich quick.

There are systemic issues and I’m no friend of the USA but crypto isn’t in anyway addressing the gripes about the current state of the world.

Most importantly: the idea that technology is going to fix things is ludicrous and it shows that people don’t understand the power of politics, governments and legislations.
I think there’s a pretty wide variety of opinions represented here. You’ll find actual debate on almost any issue. For example, not everyone sees government and big tech working together as necessarily being a bad thing, depending what they’re actually doing and why.

we switched to a heat pump last year and we’ve been mostly pleased. that said in the last cold snap when wind chill temps fell to -30 (we live in chicago) the entire system shut down! we talked to the installers and they said that when articles like this way “works down to -10” you have to understand that it’s the wind chill temp. also i’m sure there are other pumps on the market that would have faired better. we have a mitsubishi mini split.
