UK driving theory test has a part called Hazard Perception: not reacting on children milling around would be considered a fail.

> 17.7 per cent of GPUs allocated to serve only 1.35 per cent of requests in Alibaba Cloud’s marketplace, the researchers found

Instead of 1192 GPUs they now use 213 for serving those requests.

Being casually racist on the other hand is a time-honored pan-European tradition, proudly upheld by Swiss.

Multiply that by tens (or even hundreds) of teams and your app startup (either on desktop or mobile) is now a bloated mess. Happened to Office, Facebook iOS and countless others.

One solution is to treat startup cycles as a resource similar to e.g. size or backend servers.

You (and Donald Trump) seem to be using "Ukraine and Russia stop shooting at each other right now", while Ukraine operates more under "Russia stops shooting at us for the foreseeable future, 20 years at least." Russia has previously broken a number of ceasefires and written agreements (including the infamous Budapest memorandum) and so Ukraine is not super trusting to agreements not backed by anything.

And you immediately start loosing customers to insurers that either did the former or left LA alltogether. This changes $20 surcharge into $25 surcharge, causing more customers to leave, causing surcharge to increase and so on.

I'm not sure that move will help much. EVs PM2.5 footprint, is 0.5x of ICEv [0]. Good but not game-changing.

How accurate are phone accelerometers these days? Could Uber/Lyft/etc. start collecting that data from drivers phones.

1. Restrictions have to have a "controlling party": a dedicated party that controls the restrictions and can agree to lift it. Classical example would be HOA, but it can also be a seller if they want to sell property with additional restrictions.

2. The controlling party sets the price of a restriction

3. Restricted party can remove the restriction paying price set in 2 to controlling part.

4. The controlling party pays tax as percentage of price set in 2.

Those are downstream of housing restrictions to a large extent. From "Housing theory of everything" [0]:

Consider a cleaner living in Alabama. In 1960 they could move to NYC and earn wages 84% higher, and still end up with 70% higher income after rent. In 2010, they could move to New York City and become 28% more productive, and earn a wage 28% higher – and reduce the surplus of workers back home, letting them demand higher pay. But since housing costs are so much higher, the net earnings and living standards of someone like this would fall if they moved today, and wouldn’t be worth it. The same would be true for plumbers, receptionists and other professions that allow other people to specialise at what they’re best at and minimise the time they spend on things like DIY and answering the phone. By contrast, top lawyers get wage boosts that are still sufficiently higher to justify a move in both 1960 and 2010, even after the higher rents they’ll have to pay.

the efficiency is super low, but again, according to the paper, "most of the energy input was due to thermal losses at the reactor surface (83.9%)", which also benefits from square/cube law.

2.7 tons of hydrogen have a volume of almost exactly 30000 m^3, requiring storing it under high pressure in specialized containers. Hydrogen is famous for being hard to store without losses.

For long-term storage storage and losses are a problem.

> But the round-trip efficiency of the tank is virtually 100%. The efficiency of the iron-based storage is only 50%

Maybe I'm missing something, but why? As you mentioned it takes 29kj to restore 3 moles of H2 out of (3 moles of H20 + 1 mole of Fe2O3). Where does 50% comes from?

Office for National Statistics (ONS) definition of a household: one person living alone, or a group of people (not necessarily related) living at the same address who share cooking facilities and share a living room, sitting room, or dining area.

By that definition (occupied homes)/households is always about 1, so homes/households is pretty much just homes/(occupied homes).

The lower the property tax - the lower "money brought in" needs to be for building to happen.

But sometimes things we're trading off are less relevant and so the equilibrium changes e.g. losing weigh is hard, because humans evolved in low-calorie environment and being able to stock fat was important.

Funnily enough, what you're describing is actually called anti-cafe
