- Comment on ‘It’s real y’all’: People are sharing their tariff receipts, and my wallet is not ready for what’s coming 1 day ago:
The manpower is there and will be driven by necessity and availability. There’s nothing to suggest that manpower is inherently different, the goat herders and lavender farmers do their work manually not because they’re stupid or hard working, but that it’s the best available job. You might have some whining in between though, that’s what the protests and fascism is about.
In some sense, high paying tech/service jobs are just leveraging infrastructure (of communications, education, networking, political stability, power, etc.) to create the high profits enabling the cushiness of workplace.
Manufacturing doesn’t require that. It might be that with the plan signalled in the intense government (which is the main driver of infrastructure) cuts, there will be no other option in about 10-15 years time. Or at least with a larger class divide.
The strange thing is that it also generates less wealth, meaning less money for the rich folks to get rich off of. Is it just short sighted, or do they have a planned exit?

The real shits we posted yesterday
- Comment on Could wastewater plant simply heat up water past 500C to decompose all chemicals and output clean water? 2 weeks ago:
Raising water temperature from 10 to 500 degrees requires about 500 calories/mm3. That’s 2 MJ/litre, meaning if you want to heat 1 liter/second you need 2 MW with perfect insulation, so a power plant of say 10 MW.
A post industrial world citizen could probably get by on 200 l/day (US averages about 300/day. That needs 2 kW/person/day.
Total global energy production is about 630 EJ which averages out at about 12 TW.
Meaning if the whole global energy production went to treat water in that way, we have enough clean water for about 6 million people.

Article is capped at 18 views/day so can’t see numbers.
But theoretical cap of energy from a would be something like E_kin = (\gamma -1)mc². Witgout knowing anytging about the mission or engine, a 50 kg probe at a velocity of .9 c means an energy requirement of about 1,0e21 J.
Fusion of H2 to H3 yields about 340e9 J/g meaning we need about 300 million kg of fuel at 100% conversion rate, or a third if we manage He3 reaction.
Realistically heating, engine efficiency, deceleration, vibrational damping and such would probably lower efficiency to at most 40% and we end up at 750 million kg of fuel to propel a 50 kg payload.
Seems unfeasible.

Why don’t realtors share their closing prices? Seems like a good marketing tactic - “look how much I can get you for this thing”.
You could also take a look at listing prices for land of different types. Or even just call realtors and say you’re interested in buying something similar to yours and ask what the range is for them.
You could probably also buy this data from a data broker for cheap.

Check sales listings for any sold property at that price?
- Comment on Fuck geometry 5 months ago:
They’re about as imaginary as numbers are in general.
Complex numbers have real application in harmonics like electronics, acoustics, structural dynamics, damping, regulating systems, optronics, lasers, interferometry, etc.
In all the above it’s used to express relative phase, depending on your need for precision you can see it as a time component. And time is definitely a direction.

In English yes, but not in closer languages like Aramaic, Hebrew (יְהוֹשֻׁעַ (Yehoshua)) or Greek (ἰησοῦς (ioesous)).

Apparently privileged men apply when fulfilling 60% of the requirements. Women and minorities 100%.
Maybe that’s why they have the ridiculous reqs?
