RhysU··on The Dark Night of Mathematics
> The creation (or even the pursuit) of novel mathematics is one way that humans have historically accessed the ineffable and encountered the divine and mystical.

Would a mathematician please unpack this for me? A theorem is the opposite of ineffable. A conjecture may be ineffable but its pursuit reifies it. I am missing something.

RhysU··on For most US drivers, EVs offer emissions benefits and cost savings
Which hand dominant are you? My guess is you're a lefty so being offhanded with coffee in the right, which you don't have to look at, is no biggie.

Righties tend to fiddle (not shift) with the shifter or have the right hand on the wheel most of the time. Texting offhanded with the left is miserable.

The truly dedicated can drive one-kneed, heel-toe, drink coffee, and text simultaneously. But manual definitely makes texting more obviously stupid by requiring intermittent use of the second hand.

RhysU··on How the God of Israel Was Born
Except that original sin thing is pure Genesis. It's what introduces the entire need for salvation throughout all Nicene Christianity.

The Gnostic Christians who rejected the Old Testament entirety had to insert some other reason to require Christ. My favorite mechanism is how Marcion handled it, purely because his was more interesting than "everyone starts broken."

But yes, generally Catholics are not sola scriptura while most Protestants are.

RhysU··on For most US drivers, EVs offer emissions benefits and cost savings
The Manual Gearbox Preservation Society (https://tmgps.org/) is a notable counterexample.

I look forward to teaching my kids to drive stick. Stick makes driving more engaging then automatic's point-and-go. Engagement breeds attentivity. Texting while driving stick is obviously decreased because both hands are actively required to drive. None of their friends will be able to drive my manual car. I don't know why anyone would hand their kid the keys to an automatic given its downsides.

Loved that Ranger my father owned. Rolled it onto the driver's side, totalling it. Still have road rash on my left forearm from when the window broke mid-accident and my left arm dragged a touch.
RhysU··on Do we need billionaires?
Suppose we did exactly what you suggest, preventing amassing incredible wealth.

The only substitute for wealth is power and for power is wealth (with a hefty conversion fee). Amassing power would be the alternative action taken by the driven billionaire types if you take away the possibility of amassing wealth.

A bunch of stymied billionaires amassing power leads us back to pre-nationalized Europe.

At least when people amass wealth, they generally do something valuable for others.

You might enjoy reading the concept of the demiurge [1]: A lesser creating-but-not-creator deity than the ultimate benevolent god, usually portrayed as something of a deceptive character. Great rabbit hole to go down.

RhysU··on Do teachers need advanced degrees?
Teachers usually outsource negotiations to their unions and therefore largely cannot negotiate on their own behalf, even if they wanted to.
RhysU··on Do teachers need advanced degrees?
Now, add in the pre-tax earnings that would be necessary to emulate a teacher's risk-free pension. One would need post-tax investments which must be turned into an annuity on retirement. It's not a small sum.
RhysU··on New York, California pension leaders oppose 'extreme' SpaceX control structure
You can. A bunch of companies offer SMAs like this. It's a retail product, usually labeled as some smart tax loss harvesting atop the indices where you can denylist particular stocks.

Fidelity offers one: https://www.fidelity.com/managed-accounts/separately-managed...

It'd probably take you an afternoon worth of time to research then enact it.

RhysU··on New York, California pension leaders oppose 'extreme' SpaceX control structure
> But doing so would be a fair amount (by index standards) of overhead and hassle.

Any product provider, like Blackrock, would jump at the opportunity to sell them an S&P499 given the scale of those pension funds.

> Plus they'd put themselves in the crosshairs of a whole range of activists...

Not to mention putting their own jobs on the line if SpaceX outperformed the rest of the index.

The first point, that an S&P499 is easy for them but they won't do it, means they have no conviction. The second point (where I agree with you), that it's obvious we-tried CYA lacking any real teeth that'll go nowhere, means they have no courage.

They're an asset manager: put your money where your mouth is. If their hypothesis is that SpaceX governance will be bad then short the bloody thing and use the proceeds to buy the S&P499. It's not a complicated trade given their industry position and ability to call third-party providers.

RhysU··on New York, California pension leaders oppose 'extreme' SpaceX control structure
> The New York and California pension systems would become holders of SpaceX shares through their passive allocations if the company is admitted to major U.S. stock indexes.

If they have discretion, these pensions can replicate the S&P500 minus SpaceX if they don't like SpaceX's governance.

If they're forced to passively hold precisely the S&P500 then shaddup and stop active managing.

It's beyond belief how much California imports...

> [California] imports about 60% of its crude from overseas--up from 5% in the mid-1980s- about a third of which comes from the Middle East. About 15% of the state's refined fuels are also imported, much of which depends on Middle East crude.

RhysU··on The Upper Middle Class Trap
A friend once relayed his mental scale that people usually fall somewhere on...

1) Must plan to buy a meal out.

2) Must plan to take a vacation.

3) Must plan to buy a house.

4) Must plan to pass it on.

...and that these are useful subgroupings for large-scale discussion.

RhysU··on Speedup in Lattice Boltzmann Cylinder Flow
Cool.

How sensitive is the Strouhal number to viscosity at Re = 100 indirectly via the shedding frequency? My hunch is not very and so the implicit diffusion from coarsening is not having a first order effect. See Implicit Large Eddy Simulation (ILES) as the reason I ask.

How bad is the Strouhal error under coarsening of a less fancy method?

Beware, my computational fluids is meh these days.

RhysU··on US special forces soldier arrested after allegedly winning $400k on Maduro raid
Go read a few months worth of the National Review.

Many prominent conservative thinkers are not particularly big fans of Trump. They like portions of his initiatives and policies but not him as a standard bearer, because he does dumb, ill-principled stuff at odds with conservatism.

Peggy Noonan of the WSJ can't write two sentences without letting you know how much she disdains Trump, e.g.

Wilholt's essay is a nice one. But it amounts to defining the opposition in a way that's easy to tear apart followed by tearing it apart. It's a cute trick but isn't much of a basis for serious discussion.

Watch: Wilholt's essay consists of exactly and only one indefensible, rhetorical sleight of hand. Consequently, no one can honestly defend it. Attempts to do so are undeserving of serious scrutiny.

After tearing down a strawman, he claims high ground:

> The law cannot protect anyone unless it binds everyone; and it cannot bind anyone unless it protects everyone.

But you'll get a fair bit of support for Wilholt's so-called anti-conservative principle from a fair number of prominent conservative thinkers.

RhysU··on How to stop a data center in your backyard
> It really ought to be possible to structure the utility contracts such that a new data center lowers every one else’s rates instead of raising them.

That would imply that increased demand strictly decreases prices, no?

Given fixed supply, no dice.

To expand supply, one would use incrementally more expensive mechanisms to generate the incremental supply. (Because, why wouldn't you already be generating via the cheapest supply?) Either all existing customers would pay the same and the new customer would pay the higher rate OR smear the incremental costs across everyone. Prices might hold steady under the former choice but they would not decrease.

Is the idea that the new customer would unlock some better generation capabilities through capital investment? Something not already incentivized by the distributed grid?

Or is the idea that one should soak the new customer to subsidize the existing ones? Maybe rejigger some pricing tiers to push more of the existing customers into lower tiers while charging the new customer more. My guess is you're proposing this last option. I otherwise can't see how to square your suggestion with supply vs demand.

Thank you for pointing out the sidebar. I missed this because I did not understand that footnotes/sidebars were presented as links.
RhysU··on Reflections on 30 Years of HPC Programming
The author's framing "we have failed" suggests otherwise.

This section, https://chapel-lang.org/blog/posts/30years/#ok-then-why, does not mention libraries at all.

RhysU··on Reflections on 30 Years of HPC Programming
> we have failed to broadly adopt any new compiled programming languages for HPC

The article neglects that all of C, C++, and Fortran have evolved over the last 30 years.

Also, you'll find significant advances in the HPC library ecosystem over the trailing years. Consider, for example, Trilinos (https://trilinos.github.io/index.html) or Dakota (https://dakota.sandia.gov/about-dakota/) both of which push a ton of domain-agnostic capabilities into a C++ library instead of bolting them into a bespoke language. Communities of users tend to coalesce around shared libraries not creating new languages.

RhysU··on Where did my taxes go?
Many people do get more back than they put in. High earners do not:
