> In my experience, the hardest thing about quota sampling as opposed to the old RDD phone samples 20 years ago is that it's very difficult to get high education / high SES / high income respondents. High income respondents should be 10% of the population and they simply are nowhere near 10% of the pools that you get from standard recruitment methods. Can you speak a bit about a) how you recruit high income people into your pool; and b) what percentage of your pool would be high income (say HHI > $125k a year or so).

A friend of mine runs into this periodically, with her response pools over-sampling on lower income and older individuals, with a lot of geographic skewing (she does local/regional research, so appropriate sampling at a census block and/or zip code level is needed).

I've worked with her several times to fill that gap, by leveraging Facebook ads for recruitment to balance out the deficiencies in her response pool. Ad cost + incentive tends to work out to the ~$10 range per qualified response. Which is too expensive as a recruitment method for her entire pool, but she's found fantastic to reach the otherwise unreachable demographic gaps she'd have. Different demographics respond better to certain incentive structures and ad copy than others, but in general it's been effective for capturing those hard-to-get groups.

Leveraging the same avenue for re-contact is also handy if your response pool is large enough to create a custom audience to target for follow-up ads. Even out of date contact info can be useful for this. Although your IRB (if relevant) may shut that down if you didn't account for it if the language in your initial contact didn't account for it, since doing this involves disclosing the subject's PII to a third party (Facebook) for creating the custom audience.
The spelling of disk, with a K, intrigues me, since I was under the impression that disk-with-a-K was short for "diskette", meaning a circular spinning object protected inside an outer casing.

Circular flat objects are spelled disc, with a C.

Hence floppy disk, hard disk, but compact disc.

(MiniDisc is the only exception to this rule that I can think of, probably because it is a trade mark.)
Might be the most depressing thing I have ever read. People taking climate change seriously only because it keeps them in power.
>I even wish it had a name because I have observed it frequently

At least trend-wise, it’d probably look similiar to a malthusian catastrophe (population reaches environment carrying capacity at time n, and then (greatly) overshoots it at time n+1, resulting in mass die off due to starvation, taking the population well below carrying capacity)
If you don't bond neutral and ground at the main, it's still bound at the transformer.

That would be a pretty good trick. The transformer is outside my house on a pole. Two wires run to it, the hot and the neutral. The "ground" doesn't leave the house. (Other wiring schemes exist, but this is standard USA residential.)

[EDIT: brainfart, see helpful correction below. still no "ground" at the pole...]

Wouldn't a smartphone app that has a repeat-purchase item dashboard allowing 1-click orders for them cover most of those "issues"?
Yeah, I totally get you. Basically on Signal, you have the same issue as on WhatsApp; phone number required, unique per account, you can ever only have one device at a time (desktop apps are not first-grade clients but sync to phone), and all the privacy and other security issues that come with that...

I managed to get a lot of my non-geek friends over to Signal, but if things don't change I think I will switch preference to Keybase soon in lack of better alternatives.

It's unfortunate that there's no great implementation of federated IM today. XMPP is a mess and Matrix has a long way to go when it comes to that part, but from what I can tell they have a good vision and might just be able to pull it off so I am keeping a close eye on it.

Then we have Secure ScuttleButt, which I find very interesting and would love to see mature.
I'm going to go out on a limb as guess that the Harvard professors used their Business school's reputation to prop up the reputation [edit: was valuation] of the firm. We see this in many research focused universities where professors use the clout of their program to pump up their student's ventures -- typically with the professors being angel or early seed investors.

Corruption doesn't need to be illegal or against policy to be corruption. Corruption can be the degradation of institutions -- making their results less reliable -- and muddying truth.
Biggest problem I had with them is the products you could order were hard coded to the device itself. If the product you want to order doesn't have its own dash button, the whole system was useless.

(As anyone who starts an insurance company can attest to.)
From the initial story the tuning fork would be followed up by an x-ray on a positive result; so you don't really care about overall accuracy but false negative rate (since a higher false positive rate than x-ray is immaterial, since the follow-up x-ray constraints the false positive rate.)

While the exact test done may not be common, its very common for any of a variety of broadly similar (in that they work by inducing motion which will almost certainly be quite painful if there is a fracture and but usually be tolerable otherwise) "does this hurt" tests to be used in a similar role with suspected fractures, and an x-ray only ordered if they indicate a likely fracture.

this is where i expect steve bannon’s idea of favoring bilateral deals instead of large trade blocks (ASEAN, TPP etc) to backfire

in the end china will probably just find other ways to adjust and world economy starts splintering

Why not buy some companies and get some proper entrepreneurs back into the mix of management? I can't remember any recent major Google acquisitions.

With all of the failed and failing products from Google acquisitions, is that really a great idea?
Why is that unimaginable? Seems very imaginable to me, depending on the field.

I don't understand. Supposedly Thiel "claimed that Google was unpatriotic for dropping the government project Maven" - why are we talking about truthiness? How is this a provable statement?
> If it looks straight, a hairline fracture will heal properly if unstressed for a few weeks.

If the fracture isn't diagnosed and the person is one who tends to engage in the kinds of activities that lead to a suspected potential fracture of the bone in question, it probably won't be unstressed for a few weeks.

(American here.) Funny, my last several doctors visits the cash price has always been higher than the negotiated price.

These are all for services in the $150-300 range, and I was told upfront what the cash price would be, but they couldn't tell me what my negotiated plan rate was. (I inquired because I have a high deductible plan so I'll pay in the end no matter what.)

The negotiated prices were all at least 1/3 lower, and the most expensive one turned out to be free because it was classified as preventitive.

So it's even worse because you never know. It's certainly not a rule at all that cash prices are lower.

One problem with their approach IMO is there was no direct feedback on when you would actually receive the product both before AND after you press the button.

You don't know if the toilet paper is going to arrive the same day, next day, 2 days, or 2 business days. Many times if you know beforehand it's going to take 2 days to get toilet paper you'd just run to the grocery store instead.

Not just toilet paper -- even with shampoo, body wash, kitchen soap, laundry detergent, kitchen sponges, I'm usually unaware I'm running out until it actually runs out, and with most of these things I can't wait 2 days. I also live 2 blocks from a 24-hour Safeway so it's not actually an issue.

I've read every single one of Aphyr's tests. Aphyr's analyses probe a broader range of distributed consistency problems in replicated stateful databases. Consensus is a necessary mechanism to achieve distributed consistency, but if you look at the problems highlighted in products like CockroachDB and TiDB, they relate to secondary effects of failures to ensure linearizability of reads and writes.

You can have a perfectly functioning consensus algorithm and still battle inconsistent reads across nodes, loss of data on node failure or network splits, write skew, and so on. For example, TiKV uses Raft, yet the problems uncovered in TiKV have nothing to do with Raft itself. Conversely, those found in Elasticsearch are absolutely caused by its consensus algorithm, Zen, which was invented in ignorance of modern consensus research (Paxos, etc.).

If you read my comment carefully, you'll note that it's above all an endorsement of Raft, which is a milestone in that it democratizes advanced consensus and makes it a tool anyone can use. My point isn't that anyone can trivially whip up an infinitely scalable, consistent database because consensus is a solved problem, but that we have solid foundational theory to build on, to the point where it is a well-understood problem (albeit with many complicated implementations) and not black magic.

Also, I did not use the term "easy". But I also think the OP's phrasing "extremely hard" is not true, unless your requirements are extremely hard – which, again, may be the case with Kafka; scalability tends to be diametrically opposed to consistency.
No. Med tech should be as abundant as can be. But with AI there too many unknowns we're still figuring out. How to defend networks against AI attacks, hardening in general, how to handle the containment problem, the proliferation of deep fakes, deep truth and decerning between the two. And what that means at different levels. What are the critical points? What's the optimal path?
On HN there's no harm in waiting until a thing exists.
Well said. I get a lot of flak from, well, pretty much everyone for pointing out that your neighborhood doctor is likely a scam artist. Clearly I’m generalizing but just suggesting it may be the case is usually met with undue skepticism.

Not to mention, having an inside look at med school gives you a different perspective on the motivations of most rising doctors. It’s rarely about anything but lifestyle and money. I mean, they are people too, but most med students I’ve met are looking out for number one first, and anything else is a distant second.

I think it's a mistake to confuse JVM languages with Java. But that aside, By "Java is the new COBOL", I'm not saying that Java today is COBOL today. I'm saying it's a dominant language for legacy apps and a lot of "enterprise" coding in shops that already have a heavy Java investment.

But relatively few new companies are doing new work in pure Java, so it's definitely headed down the same road. And there are definitely plenty of companies where people will blink a lot more than twice if you propose building something in Java.

That's not to say it's bad; I've written a bunch of Java for money, and may do so again. But I think it's hard to justify in a lot of environments, and correctly so.

TFA is a bit more abstract than you realize, and perhaps that abstraction could mislead the unwary. It is technically correct, but makes a distinction you've missed. If a gremlin cuts the (green) wire between my breaker box and my ground rod, the system is no longer "grounded to Earth", so it wouldn't handle lightning strikes well. However, the "EGC" in every house circuit is still bonded to neutral at the box, so breakers will still trip when the wire inside my clothes dryer rubs against the metal body. That is the function of the EGC. The EGC itself does nothing to protect against transient earth potentials like lightning strikes. That is the job of the grounding rod etc. Just because both wires are green, doesn't mean they're doing the same thing.
> Funny, my last several doctors visits the cash price has always been higher than the negotiated price.

There is nothing funny about it. Once you tell the provider that you have insurance, the price they can quote you is in their contract with the insurance company. You need to go somewhere new and tell them you do not have insurance to get the real price.

yea, that is definitely true that they are compensated very well, but i was thinking in a more “equitable” way considering the insane profits they are generating

if you added say half the profits to employees and half the stock as well, they could become multi-millionaires even sooner.... maybe it’s just my bias, but i feel like if those employees were really empowered by their earnings they would be more entrepreneurial and start all kinds of new ventures

i guess this is just my crazy idea, but it’s something i feel strongly recently... it’s just weird to me to see such huge amounts of capital just sitting there (or being used in buybacks)

Well this is not a new thought. That discussion goes back to the early days of industrialization and involves thinkers like Karl Marx and Friedrich Engels, where a chain of thoughts (alternative to "socialist mainstream" of giving the "production capital" to the state, where those two mentioned ended up) to put companies into a collective/cooperative, where the company is owned by the workers, thus workers make the decisions and take the profits. These thoughts are part of the roots of many social democratic parties in Europe. While this debate came to an end when the East collapsed, the capitalistic system won an Social Democrats became more market oriented (i.e. "New Labour" in UK or German SPD with Gerhard Schröder's reforms of unemployment and social systems)
