Insurance requires risk transfer but that's different from cross-subsidization. It's fine for 100 equally flood-prone houses to all pay the same insurance premiums even if only 1 of them floods in a given year. But people in a les

There's no need to draw a discrete line and say it's inappropriate to be on the wrong side of it. People should be able to live where they choose. But people should also pay actuarially fair insurance premiums and market-driven pr

It's like the opposite of clickbait. The author did, upon information and belief, taste Honda's spicy rodent-repelling tape, and made a strong case that she will in fact do it again unless someone stops her. Truly giving the peopl

I live in Palo Alto and previously went to grad school in Berkeley, and I can corroborate. Frankly you wouldn't need to spend more than a couple hours in either location to pick up on those vibes.

Electrification wasn't just an efficiency thing, it also made the service much better because of the faster acceleration - IIRC my travel time to SF on weekends went from 75 to 50 minutes, which opens up a lot of use cases.

BART is better than it was but still bad. Caltrain is totally fine though.

The 6.0% margin (for UnitedHealthGroup as a whole) already includes that. UnitedHealthcare (the subsidiary health insurer) had a slightly lower operating margin of 5.6% in Q3. https://www.unitedhealthgroup.com/content/d

My primary email uses a .ng domain, currently through Fastmail. I’ve had exactly one site reject it and zero spam filter issues that I know of. The only real issue has been that it’s a pain to tell people in person, so I usually end up just

If you parse e.g. a json file containing a scalar to an R object, that scalar will be represented as a length-1 vector. I get what you’re saying, but “it doesn’t let you access scalars” would suggest to me that it can’t parse or represent v

I’m by no means an expert in weather forecasting, but I have some familiarity with the methods. My understanding is that non-“AI” weather models basically subdivide the atmosphere into a 3d grid of cells that are on the order of hundreds to

I think he only made that claim referring to the profits that the banks earn from their relationships with the crypto companies, not the total profits made by the crypto companies themselves (though both could be true).

It wouldn’t have to scale, but I’m glad that it did. It’s likely that there’s been somewhat more innovation and economic growth in the world over the last ~decade than there would have been if YC stayed smaller.

One way I've seen this done in practice is to construct an offline model that produces an initial set of posterior samples, then construct a second, online model that takes posterior samples and new observations as input and constructs

PyMC can use NumPyro as a backend. PyMC's syntax and primitives for declaring models are much nicer than (Num)Pyro's, as is the developer experience overall. But those come at the cost of having to deal with PyTensor (a fork of a

I'm a data scientist, and my impression is that the growth of data science as a profession over the last ~decade has enabled companies to price more efficiently than they used to. That in turn was enabled by technical improvements like

I think it is stupid to vote based on how a politician talks rather than the expected impact of their proposed policies, though of course I realize that that’s how elections have been decided in practice for as long as representative gove

It’s not really about dividends. If you buy a share of Amazon stock, you’re getting a cut of the value that a million+ people are producing every day by writing code or moving stuff around. The value most workers create for their employers’

Reserve requirements are completely different from capital requirements. US banks are required to hold about $108 in assets for every $100 they hold in deposits, and their actual holdings are typically in the range of around $110 to $115 in

At least for CSV, there's a divergence between usage in practice and the spec. The spec requires CRLF, but all of the commonly used tools I've encountered for reading and writing CSVs can read files with CR, LF, or CRLF line endin

Many contracted projects are contracted on a longer timescale, often weeks or months, compared to ridesharing where the outputs are expected within minutes. Contractors in other fields can often choose when to work on a day-to-day basis, bu

Just from public information my impression is that prestige was never a goal while scaling was in the plans from fairly early on. Anecdotally, some of the best recent founders I know are opting not to apply, which I think is a bad sign. But

One concrete example: R has 5 distinct, actively maintained class systems, at least 3 of which are somewhat commonly used for new projects. I.e., there are 3+ reasonable ways to declare a class, and the class will have different semantics f

Manifold [0] has markets on this sort of thing, but it primarily uses fake money. (They're working on a real-money "sweepstakes" thing, which I'm not super familiar with.) If you're outside the US and looking for a

Isn't this functionally the same thing that the author already did, just with N=10 and filtering on the first digit instead of the last?

The comment you replied to seems to be targeted at managers trying to advocate for their teams, not at individual contributors trying to advocate for themselves. I agree that reaching out to the compensation team as an IC is generally not g

Honestly, if you just block or ignore the feed, the other features - profile, social graph, messages, job postings - are basically fine. My biggest complaints on the job seeking side are the mediocre recommendation system and the lack of hi

I think each category of Bayesian described in the article generally falls under Breiman's [0] "data modeling" culture, while ML practitioners, even when using Bayesian methods, almost invariably fall under the "algorith

An implicit shared belief of all of the practitioners the author mentions is that they attempt to construct models that correspond to some underlying "data generating process". Machine learning practitioners may use similar models
