fennecfoxen··on In microtransit, passengers order a shuttle van instead of having to take a bus

fennecfoxen··on How did REST come to mean the opposite of REST?
I tend to find it helpful to ask, "is this proper REST as in HATEOAS, or is just 'REST-ish'?" It's usually just REST-ish: predefined URL patterns, roughly 1:1 with specific resource-APIs; they care about your HTTP verb and return JSON (but usually not with a lot of URLs in that JSON).
fennecfoxen··on Crimes against transhumanity
The Federov link towards the end of this piece remindeded me of some older science fiction on the topic, specifically, C. S. Lewis, That Hideous Strength (published 1945, just before the atomic bomb got the genre's attention.) In this work, the central conspiracy has just (haltingly) achieved the artificial resurrection of a human brain, and this capability is the lynchpin of their scheme to take over the world. In the excerpt below, our protagonist Mark finally learns of the advance from the scientist Filostrato, while the slightly deranged preacher Straik theologizes (he might have been Federov-inspired.) It's all very much in line with the incredible possibilities of consciousness-abuse that is covered here.

--

"It is the beginning of Man Immortal and Man Ubiquitous," said Straik. "Man on the throne of the universe. It is what all the prophecies really meant."

"At first, of course," said Filostrato, "the power will be confined to a number--a small number--of individual men. Those who are selected for eternal life."

"And you mean," said Mark, "it will then be extended to all men?"

"No," said Filostrato. "I mean it will then be reduced to one man. You are not a fool, are you, my young friend? All that talk about the power of Man over Nature--Man in the abstract--is only for the canaglia. You know as well as I do that Man's power over Nature means the power of some men over other men with Nature as the instrument. There is no such thing as Man--it is a word. There are only men. No! It is not Man who will be omnipotent, it is some one man, some immortal man. Alcasan, our Head, is the first sketch of it. The completed product may be someone else. It may be you. It may be me."

"A king cometh," said Straik, "who shall rule the universe with righteousness and the heavens with judgement. You thought all that was mythology, no doubt. You thought because fables had clustered about the phrase 'Son of Man' that Man would never really have a son who will wield all power. But he will."

"I don't understand, I don't understand," said Mark.

"But it is very easy," said Filostrato. "We have found how to make a dead man live. He was a wise man even in his natural life. He live now forever: he get wiser. Later, we make them live better--for at present, one must concede, this second life is probably not very agreeable to him who has it. You see? Later we make it pleasant for some--perhaps not so pleasant for others. For we can make the dead live whether they wish it or not. He who shall be finally king of the universe can give this life to whom he pleases. They cannot refuse the little present."

"And so," said Straik, "the lessons you learned at your mother's knee return. God will have power to give eternal reward and eternal punishment."

fennecfoxen··on Inflation rose 9.1% in June, even more than expected
> It just feels like there is about to be an asset wipeout across the spectrum

That's generally expected when interest rates rise. Most assets have value now because they ought generate returns in the future -- but you can get interest between now and in the future, and if you can get a lot of that interest now, why would you spend so much on what is still a long way off?

The slightly cheaper tactic may be to actually to buy a fully refundable fare (usually for thousands) for much later in the day, and then cancel it and ask for a full refund.

fennecfoxen··on Governor Newsom announces California will make its own insulin
I suspect they're not actually as good as the newer insulins.

"I am an endocrinologist working in the biopharmaceutical industry, and it surprises me that we still need to scapegoat drugs like insulin for high drug prices (“Injecting Some Insulin Reality,” Review & Outlook, April 6). Absent from the discussion is the dramatic improvements in marketed insulins over the past 25 years.

When we talk about modern insulin therapy, we aren’t talking about the old insulins. These agents required patients to carefully plan what they ate well before they did—they should rightly be cheap. Modern insulins allow patients better control of blood sugar and more flexibility. It takes large investments to develop medications. How much is it worth to not have to determine what you will put in your mouth 30 minutes prior to doing so? It is good those days are over."

fennecfoxen··on The Benefits of World Hunger
The author of this piece has a book, "Freedom from want: the human right to adequate food". The publisher's summary quotes Richard Pierre Claude, founding editor of Human Rights Quarterly and professor emeritus, University of Maryland:

"As a legal claim, the 'human right to adequate food' may seem thin gruel, but George Kent enriches the concept with data-based policy analysis, compelling ethical arguments, and a full review of concerned international, national, and nongovernmental organizations. He persuasively makes the case for accountability where the face of famine, malnutrition, and starvation confront the hands of those who hold political power at every level in our new global economy."

fennecfoxen··on FedEx to close data centers, retire mainframes
> The part that’s always missing with these rent vs buy analyses on HN for some reason is that it’s totally ignoring the opex cost of operating your own hardware which is going to be non 0.

Effectively hiring, retaining, evaluating and rewarding competent staff is hard. Even at a big company the datacenter can be a really small world, which makes it hard for your best employees to grow. Things are especially hard when you don't have a tech brand to rely on for your recruiting, and the staff's expertise is far outside the company's core business, making it harder to evaluate who's good at anything.

fennecfoxen··on America needs supply-side reform
The current administration's ideas of supply-side reforms starts with the Defense Production Act and ends with Executive Order 11615. The opposition party's idea of supply-side reforms involves looking for additional ballots in Georgia.

Hang onto your inflation hedges, because it doesn't look very good for America.

fennecfoxen··on Extreme heat, drought will permanently scar California and its social fabric
Yes, metric is nice.

In the meantime, the acre is the standard unit of area for farms, fields, residential property, other property, parks, and certain other uses of land. A house on a quarter-acre lot generally has a backyard, and would fit in most suburbs. A house on a half-acre lot has a big backyard with plenty of room for your kids to run around. A full acre is getting pretty decently big — it's more like the size of a small field that you'd use for growing crops (which is the origin of the measure: 1 farmer-pair-of-oxen-plow-day.)

Rain is measured in inches and feet.

Just multiply two values people use in practice and get another that they can use in practice: acre-feet. Are you forecast for three inches (0.25 feet) of rain, on your forty-acre property? That's 10 acre-feet of water you can get from the sky instead of the irrigation authority. Like most things customary, it's easier to use in some ways, harder in others.

fennecfoxen··on Ohio State University secures trademark for use of the word 'THE' on clothing
Miami University (Oxford, Ohio) just for overkill.

I would also like to draw attention to the distinction between Wake Forest University (of Winston-Salem, NC, via GSO airport) and Wake Forest, NC (closer to RDU airport). The latter was of course the home of the original Wake Forest Baptist Manual Labor Institute.

I’ve had to pick someone up at the wrong airport, you see. It was quite a drive.

fennecfoxen··on Ask HN: What are examples of common beliefs conclusively invalidated by data?
> 1

Let’s see. It’s the 1980s, and our economy has been beset by 8-12% annual inflation, amidst general stagnation.

Is there anything we could do in this situation to increase economic output, and thus the supply of goods and services, and maybe even increase employment at the same time? Might any of those, perhaps, be promoted through the investment of capital, in any manner at all?

No!!! Like Nixon and Ford and Carter before us, we shall maintain very high taxes on the returns from capital investment, as we try subsidizing demand once again with stimulus spending! It’s sure to work this time.

fennecfoxen··on Citybound – A city building game using actor-based distributed simulation
> It is quite trivial then to get a fortress up and running and produce far more food, drinks, and goods than you ever need and grow your wealth rapidly.

At that point it turns into a big-system management game with a variety of mechanisms to trip you up, starting with the raids and megabeasts attracted by wealth, vampire infiltration, cranky nobility, and other ways that your system turns self-destructive.

That doesn't make it a great game — it can be incredibly tedious — but, it sounds like you played until you reached prosperity, and just declared the first 1/3-of-the-game-tops as too easy.

fennecfoxen··on Voyager spacecraft begin to power down
Generally it'd be more efficient to build a nuclear power plant with the materials from the RTG, and power many houses.
fennecfoxen··on Construction is life
> It doesn’t feel very efficient, especially residential construction. My neighbor is building a garage with some finished space above. It’s sat without a garage door for literally months now - everything else is done.

If all you have to improve the construction industry is better scheduling and supply-chain management, that's something. But the poster above seemed to be hinting at things more like new construction techniques.

fennecfoxen··on Construction is life
Investment in new techniques is limited due to the limited prospects of saving money. Construction is an efficient business; gains are possible but hard, and material transportation prices play a much larger role than one might be used to.
fennecfoxen··on Construction is life
If you are looking for economist words I think the one that matches your description is the phrase “rent seekers.”

Your value judgment on investment is, ah, popular in some circles, but its placement on the Y Combinator news forum is ironic.

fennecfoxen··on Construction is life
It’s not for construction and maintenance. It’s for inspection. The scaffolds exploded after some facade bits fell on someone and they passed Local Law 11, and they radically increased the number of inspections and basically required scaffolds for them.

The correct modern solution is probably mostly drones. This idea has been floated but is not presently legal, and the scaffold companies will lobby the government and cry bloody murder, so expect the scaffolding to continue for the next 300 years.

fennecfoxen··on How Many Tracks Do Train Stations Need?
> Let people wait on the platform as the train arrives. This is something that basically every train operator but Amtrak does.

In no small part because the platforms are too narrow — something that getting rid of several tracks would readily fix. (Just fill in the space between two platforms and you have a nice, very wide platform.)

fennecfoxen··on How Many Tracks Do Train Stations Need?
For NYC diesel trains, you're talking about stretches like the one from Croton-Harmon to Poughkeepsie (by car, it's about 40 miles). I'm not sure whether this counts as "short."

fennecfoxen··on Ten years after the Higgs, physicists face the nightmare of finding nothing else
> I can't speak to whether it would cost less to do these experiments in space, I'm no expert on the colliding of particles and the implications thereof.

I'm a nonexpert who has some vague idea of how these things work.

There's two kinds of accelerator: circular and linear. In either case, you have a tube, often underground, a bunch of accelerator components along the tube, and a detector component. I believe but I am not sure that a key advantage of the circular one is that you can accelerate the particles in the beam as they take multiple loops around the tube. The disadvantage is that when charged particles turn they lose energy by emitting electromagnetic radiation, and the whole point of the accelerator is to stuff these particles full of energy to make interesting collisions. This is mitigated by having higher-radius accelerators, which is the key reason we build things like the Large Hadron Collider and make it so very large in the first place, instead of just trying to add stronger stuff at existing accelerators.

So what do you intend to do in space?

The quasi-achievable near term might see a linear accelerator that consists of two components orbiting and firing particle beams into a third (the detector) because we are obviously not orbiting the mass of the LHC in the near term, and we're not orbiting anything that's rigid and also substantially larger than a rocket payload. It will no doubt be tricky to align the beams, as the orbits are ellipses and the beams need to be approximately straight lines (or close enough, blah blah spacetime). But the fundamental problem is that you're going to need to do all your acceleration all at once, at the accelerators, which immediately negates any possible advantages you could possibly have from space.

Perhaps you could do something very clever with an orbit-sized circular accelerator with accelerators spaced at intervals around the planet. You'd need a lot of launches of some intense equipment (I believe the Earth-based accelerator components are giant supercooled magnets). You'd also need an energy source, lots of engineering prowess to get everything in good working order (LHC bringup was very hands-on) except any adjustments will have to be done in orbit, and then when it's running you'd face the problem of LOLmaintenance.

I'm going to be honest, I'm more skeptical about this than about the Mars colony.

fennecfoxen··on Scotland starts renewed case for independence
More directly, Northern Ireland is where the king of the English nation once sent the peoples of England to colonize the lands of the Irish nation. These peoples thus settled have remained culturally distinct as the favored elites of the ruling colonial power, and are presently the majority in the area, which is why the area did not join with greater Ireland during Irish independence.

The people of Northern Ireland today tend to want either continued union with the kingdom ruling Great Britain, or union with the rest of Ireland — depending whether their families are of British origin or Irish. The thought of post-Brexit passport control and customs for travel between the territories comprising Northern Ireland and either Great Britain or Ireland is thus a major political football (far worse in the case of the border with Ireland, because it is a land border and that requires walls.)
