Re:Ask HN: What are you working on? (May 2025) on Sunday May 25, 2025 @05:06PM (#44091131)
modeling the heat transfer modes in Enceladus' icy shell that rests above its liquid water ocean. previous modeling has assumed that all heat transfer is conductive, but using dynamical simulations i've shown that under certain conditions convection can occur at in the shell. specifically, these conditions are having a thick enough ice shell, the right amount of porous fluffy ice deposited from the plumes at Enceladus' south pole which jet water into space through fissures in the crust, and the right thermal conductivity of this porous layer.

now i'm starting on adjusting the model to include the liquid water ocean underneath the shell and observe the effect of changing viscosity gradients in the equilibration of the ocean and ice shell, as well as adding in compositional impurities (chloride brines) and tidal heating effects.

Trotting this out again because somehow it hasn't completely saturated the internet yet:

i procrastinated on my bachelor's thesis for ~5 years. the school ended up changing the graduation requirements before i finished it.

never underestimate the power of stubbornness.

maybe, just maybe, having friction in logging into web services is a good thing.

i, for one, am not a fan of the tendency for every web service to require an account in the first place. making it easier for people to log in to these unnecessary accounts is helpful in discouraging this practice, as it will decrease utilization of services which require such superfluous accounts.

sounds like the devs over at SAP need to unionize if they want to stop pushing user-unfriendly software
Re:White House Is Mulling a Ban on Bitcoin Mining on Saturday September 10, 2022 @07:47AM (#32789788)
enforcement would probably happen at the level of the power utility. large mining operations have agreements with utilities to buy power at wholesale prices, the utilities know what the power is being used for

the real beneficiaries of this would be small miners (small business owners?) who either use their own locally generated power or the residential grid. oh, and all the people who don't mine in the US

a proper marxist critique of Graeber's "Bullshit Jobs" hypothesis:

Alienation Is Not ‘Bullshit’: An Empirical Critique of Graeber’s Theory of BS Jobs https://journals.sagepub.com/doi/full/10.1177/09500170211015...

from the conclusion:

>This article highlights that alternative theories grounded in empirical research are required to understand the social suffering caused by the feelings of useless work that Graeber observes. Therefore, our third major contribution is to demonstrate the value of Marx’s writings on alienation. We take inspiration from Marx’s understanding of alienation to investigate whether the social relations of work can explain why millions of workers do not feel that their work is useful. In particular, we focus on the ways in which the development of workers’ human capacities may be fettered by social relations at work.

Re:The dictatorship of the articulate on Thursday September 01, 2022 @01:34AM (#32672387)
right, it's the fault of regulators that every major industry has come do be dominated by a small handful of conglomerates that survive by mimicking each other and consuming every smaller challenger that might one day, through the power of innovation, grow and compete with the existing monoliths.

oh wait, that's the opposite of regulation that caused that. my bad.

Good. The only way we're going to get these selfish Americans to sacrifice anything is if we force them.
agriculture provides me with food to eat. lawns do not. i would rather have food to eat than useless patches of grass.
twitter is interested in making money. there's far more money to be made pandering to governments than in pandering to dissidents. the content moderation policies are just extra steps in justifying that stance.
Interesting that I haven't seen any discussion of the housing monopolies that were castigated in that study, given how vigorous discussion was on that topic when that study was posted here.

The study largely blames HUD and builders unions for squeezing manufactured home builders out of the market with zoning laws, government programs which favored stick-built housing, and further regulations which make buying and owning a manufactured home undesirable. This discussion of course only applies to the US.

Re:Nobody wants to teach anymore on Monday August 22, 2022 @07:02AM (#32549789)
Pay teachers more and more people will teach. On a website so dedicated to discussion of free market principles, the amount of rationalization people put themselves through to avoid this simple conclusion is both funny and tragic.
i can only sleep on my side. you get used to tucking your chin in as is described in the article pretty quickly
been sleeping without a pillow since college. my neck problems disappeared immediately when i made the switch. there are so many unexamined habits in our culture. a lot of defaulting to short-term comfort without considering what the long-term consequences might be, too.
i don't know what to call uncontrollable positive feedback loops in the global temperature if not a "collapse"
excuse me, what? they got their housing under control just as soon as they were able to modernize their agriculture-based economy into a modern industrial workforce in less than 50 years

maybe the millenia old concept that's been culturally relevant enough to stay in our lexicon all that time is a better explanation than pop psychology, yeah.

for all the miracles of modern social science and statistics, the ancients' theories have a critical advantage over ours. they've had time for their hypotheses to be borne out.
