galimaufry··on What we know about CEO shooting suspect
I wonder if there is a niche to ameliorate this sort of thing by offering payday loans on insurance payouts.

The incentives are pro-social: insurance companies have an incentive to delay payouts, because their profits come from interest (they pay out more money than they take in) so the longer they can hold onto money the better. But that's reversed for this hypothetical loan issuer - they want to make the payout as fast as possible in order to earn as much interest as possible as quickly as possible.

And if there's a systematic tendency for medicaid advantage plans to deny claims that eventually get approved, and if you could predict which ones will get approved 'just' by really understanding what medicaid would approve, then this might be self-sustaining or even profitable?

galimaufry··on Analysis of 200M newspaper pages: Sentiment has collapsed over the past 50 years
> Purchasing power has collapsed

But is this actually true, or just something that declining economic sentiment in the newspapers has led us to believe? People are consuming more food, more education, more square feet of house, more travel. My sense is that is surprisingly hard to find a quantitative signal that purchasing power has collapsed.

Maybe it is just that positional goods (access to the best neighborhood in the best city) get harder to obtain as the population grows?

galimaufry··on NYC jail complex to be restored into citywide green energy hub
Corrections staff at Riker's island get unlimited, unauthenticated sick leave, which may partly explain the large number here, along with their employment as clerks, bakers, door control, etc.

Incidentally this is what I meant above, about the union being out of touch: unlimited sick leave makes staffing unpredictable, which makes work unpredictable and frankly dangerous, which makes guards take more sick leave in a vicious cycle. The union has weaker-than-expected motivations to fix this, because everyone with seniority does not actually work in the housing blocks.

galimaufry··on NYC jail complex to be restored into citywide green energy hub
Riker's island is very poorly designed. A big part of the problem is that it is quite inaccessible from the rest of the city. This has a ton of knock-on effects:

1. There's a severe shortage of guards. Anything that could make working in the jails more attractive will help, and a 2-hour commute is not attractive.

2. Getting medical service, prisoners with court dates, lawyers, etc. on and off the island is really really slow.

3. The jail has insourced a lot of services (for example they run a large bakery). These get staffed by corrections officers. This both makes staffing harder, and the existence of these plum positions has weird effects on the politics of the corrections union (people with power in the union are not actually working as guards and are out of touch with the reality of the jail)

Moving to a model like the Tombs, with the jail directly above the courthouse, makes way more sense.

In addition, the buildings on the island need a serious revamp (e.g. there is no automatic access control, so every major door needs a guard physically standing there to let people through and climate control is broken). As long as you need to seriously renovate anyway, might as well just build a new jail where it should have been put in the first place.

Well yeah, it is explicitly intended as a signal that investors can use to select virtuous companies.

galimaufry··on Our fundamental right to shame and shun the New York Times
I've heard it called a "non-central example". That has a negative connotation though, I wish there was a more neutral term. The statement "all natural numbers are greater than 1" is false, and it's not helpful to object that 0 and 1 are noncentral examples.

galimaufry··on Ask HN: Why is today's Internet experience so user hostile?
Sure, but then they just send you a letter correcting your mistake, you OK it if it looks right, and either they send you a check or you send them a check. You don't have to pay a fine and you don't get audited.

(I am not a tax lawyer nor an accountant, but I have done this 4 out of the last 6 years.)

galimaufry··on VCs are financing an economy of servants
It's the second one. This kerfluffle was started by Blackrock moving into real estate. Blackrock is a retail investment-management company that everyone from the middle class up invests with.

So, it's not really "you will own nothing and be happy about it", but rather "you will own 0.1% of 1000 houses rather than 100% of 1 house, and be happy about it."

galimaufry··on What's bad about Julia?
You're not wrong. I guess what I'd like is the ability to apply (up to) two type annotations, with the second one a subtype of the first, and use the first for dispatch and the second for documentation/testing/static analysis...

... which actually seems like it might be doable with some macros? Those are beyond my ken right now, but the goal would be

  @doubly_typed f(x::Number|Integer) = x
  f(6.0)            # Same as g(x::Number) = x; g(6.0)
  @strictify f(6.0) # Same as g(x::Integer) = x; g(6.0)
Then you would use @strictify when running tests to ensure that the stricter types in your codebase are all compatible. But you'd still need to figure out what to do about return types and the help command...
galimaufry··on What's bad about Julia?
One thing that I miss coming from python to Julia, is typing-as-documentation. In python I often write type annotations that are much more restrictive than they need to be. They work as checkable documentation of how a function is expected to be used (and under what circumstances do I guarantee it will work), without restricting how it can be used.
galimaufry··on Third member of U.S. FDA advisory panel resigns over Alzheimer’s drug approval
As I understand it the issue is

* Currently the US welfare agencies will provide ~any FDA-approved drug for someone with the illness for which the drug was approved

* In this case, they probably won't - in the worst case scenario it would double their spending on prescription drugs and seems unlikely to help anyone

* So this is going to sever the link between FDA approval and medicaid spending.

* Now you have an awkward situation where agencies that not really equipped to make judgements on dug effectiveness, and which are not insulated from politics, have to make those decisions.

This could all work out for the best in the long term but may also be very awkward in the short term.

> They don’t run corrections based on the number of simulations they run, they don’t take into account other variables, etc

I think this looks like a bigger problem specifically because you are in AutoML.

Suppose you are training a GAN. There's notoriously a certain amount of luck involved in traditional GAN training, because you need the adversary and the generator to balance each other just right. So people try many times until they succeed. Probably they were not even recording each attempt, so they do not report how many times they had to run before getting good results.

From an AutoML point of view, this is BS work - the training procedure cannot be automated, and (apart from using the actual seeds) the work cannot be reproduced.

But from the point of view of everyone else, maybe it is fine. They get a generator model at the end, it works, other people can run it.

> "At graduate level, you should cultivate [peers and a concentration] such that your intellectual correspondence is publishable." ... I did not take it at the time as immediately translatable into a [simply translated?] phrase I have heard since: "friendship corruption."

This seems misguided, and I certainly hope that this 'friendship corruption' concept never catches on. There are great papers that started as letters and were later completed by the sender, recipient or both. No one should feel ashamed about that, and no one should feel ashamed of developing friendships with their colleagues.

galimaufry··on An experiment caught a quantum system in the middle of a jump (2019)
I agree that there is "information" in the colloquial sense there, or even in the Kolmogorov sense. I don't understand how there is information in the entropy sense, because I do not see a random variable anywhere in this story.
galimaufry··on An experiment caught a quantum system in the middle of a jump (2019)
I'm not sure this answers the question. The wikipedia page is about the entropy of a probability distribution. But the information speed limit is supposed to apply even if everything is totally deterministic.

If I write a single, 100% certain message and put it in a spaceship it still cannot go faster than light, even though there is no information transfer (entropy of my message (a constant random variable) is 0).

(I'm not saying you are wrong, I am asking to be corrected)

> you also don’t have the right to tell a community to change its character or compensation.

Sometimes you do though. There are real cases where the acid rain produced by City A falls entirely on City B. Surely in that case City B should be able to tell City A to change its character? Local government alone will never solve a problem like this.

The people who pay the price for SF's character are not people who live in SF, but people who commute a long way from outside the city limits, or who don't live in the Bay Area at all but would if they could. The SF government should care less about them than about current SF citizens, but their interests aren't zero. Which is why you need a higher level polity like the CA government to overrule the local government .

It's a bit of a chicken-or-the-egg problem. If more people move to SF then more brunch places will open and the city will be able to afford to run more busses.

Maybe SF could credibly commit to adding more density in the near future, but not immediately? That way speculators open brunch places before the customers arise, and there isn't a brunch shortage?

galimaufry··on Adoption of Mypy for Python type checking: 45% already use it, 40% don't plan to
I was just thinking about this. Seems like it could also be great if the type system could make a distinction between vectors and dual vectors, alleviating "you got the wrong axis" errors. But maybe for something like that you really need vector space objects like in Sage.

> Names are almost laughably bad for this purpose, for having multiple forms ("N SECOND ST" vs "NORTH 2ND STREET") and for being terrifying vague (so many, many Main Streets).

libpostal (open source, open data location parser) might help with this. Between using it to parse the name, and supplementing this with the city name (using reverse geocode with imprecise coordinates), you might be able to get something useful.

Here's what's on nytimes.come right now:

- UK imposes harsher crackdown in London

I'm not going to conclude from this that the UK relaxed its lockdown, the vaccine will not be shipped, and Pompeo said Russia was not behind the hack.

The happy medium is: know when a newspaper was in a position to know the truth and trust them if they were, or if the article explains its evidentiary basis in convincing detail.

True, but Bell labs is hardly an example of normal capitalism. As I understand it, AT&T during the Bell labs era was more like the East India Company, or a PRC-style state-controlled corporation, or Pacific Gas and Electric.

(I find that this is an under-explored option in discussions of socialism-vs-anarchism-vs-capitalism these days. State-controlled corporations seems to have a very good track record. But I haven't seriously studied this.)
