Adverse selection inflates premiums, simply because people who need insurance are the ones who buy it.

The point of insurance is to transfer* risk to the insurer. The insurer does that by identifying a group that is homogenous enough that their premiums are just slightly over the payouts.

So an insurer can improve competitiveness by selling multiple products that cover different risk groups. I imagine that for Stripe, the risk variance falls in a fairy narrow band: bounded at the low end by not being worth insuring, and bounded at the high end by merchants losing their account.

* As opposed to say retaining risk, e.g. you don't buy collision on a beater.
Ask HN: What demographic to target with a new social media site?
I have a prototype of a site with potentially broad appeal when it gets big enough, but I worry that community fragmentation of multiple sub-communities early on would slow the growth of the site, so I can really only target one or a few closely related demographics. The site's main method of growth will be through a combination of novelty and network effects, and it will differentiate itself from the competition by having an early focus on creating a mentally positive environment by suppressing negative content to a certain extent, thus avoiding the impacts of negativity bias[1]. This will hopefully avoid the negative outcome of sites like voat.co and lead to the site growing quickly.

Do you know of a demographic that is underserved by current media aggregation sites? Any advice on how to target that demographic and meet their needs?

I think this is the best part:

>>The best expose of what happened can be found in a detailed 1998 report from the Columbia University School of Journalism titled "The Myth of Tiananmen and the Price of a Passive Press". Prepared by Jay Mathews, a former Washington Post Beijing bureau chief, it notes how the Western media's pack instinct created the false massacre story.

Here's the link for the article they're quoting: https://archives.cjr.org/behind_the_news/the_myth_of_tiananm...

Pull quote: A common response to this corrective analysis is: So what? The Chinese army killed many innocent people that night. Who cares exactly where the atrocities took place? That is an understandable, and emotionally satisfying, reaction.

I guess they're just really hoping nobody actually reads the article, and instead just goes "oh, false narrative. case closed"

It might be possible to build a set theory and the rest of mathematics based on the integers, but I am sure the result wouldn't look simple.
That one is not a technology one indeed. I intermingle some non-tech ones just to show that there are curious simple things everywhere, and that there's more than just tech in their lives.

I love learning how to tie new knots. My problem is that, unless I use them regularly, I tend to forget how to tie the more complicated ones. My go-to knots are the bowline, sheetbend, tenter's hitch, the alpine butterfly, and the bloodknot, for joining fishing line.

Great site!
...and, most menacing of all, they may send your email to other people!

More seriously, these things all seem like essentially mandatory features for an email provider today. If you don't provide fast search of my inbox you probably aren't a serious option for me, and a spam filter is an absolute must-have. How can they do those well without all of the above?
SEEKING WORK - Florianópolis - Remote preferred

I'm a developer who specializes in building scrapers and crawlers. I can either build them from the ground up, or help optimize crawlers you already have.

I build fast and efficient crawlers by analyzing the scraped source and determining best possible method for it; be that parsing HTML, querying APIs directly or using webdrivers optimized to run headless and skip downloading unnecessary resources such as tracking scripts and images.

My preferred tool is Python, but I'm comfortable if some interop is necessary too.

Feel free to contact me with any questions you might have.

Don't underestimate the programming aptitude they have already.

I coached a lego robot team for kids of similar ages. We spent one tenth the time that I expected teaching programming, and double the time I expected teaching mechanics.

Almost zero instruction was needed on ifs, loops, and stitching together commands and functions. Conversely, teaching what happens when a little gear drives a big gear was brand new to them.
Perhaps one distinction is that 'breaking up Google' is really disentangling separate services from one vertically integrated company (Search != GDocs), while what is happening with 'breaking up Netflix' is taking a single category of service and making it worse, less convenient, and more expensive, because it now takes 4 different subscriptions + ui's to navigate to find what used to be under a single service.

What ever you do, you should incorporate the say command. Have the computer talk to the students. It will be a great attention grabber.
I'd suggest the following.

get-command add*group*

Or for brevity

gcm add*group*

For reference, the Bash version is this:

compgen -c | grep group

Edit:

Let's get crazier. You want custom tab completion to focus on the command's noun plus Bash style completion.

$Function:OriginalTabCompletion = $Function:TabExpansion

function TabExpansion($line, $lastWord) {
if ($line -match ('^!(.*)') {
$lastWord = $lastWord.trimstart('!')
Get-command -noun *$lastWord*
} elseif {
OriginalTabExpansion $line $lastWord
}
}

OK, this brings up a question I've been meaning to ask tech-savvy Gmail users. The typical Hacker News reader is surely aware of the extent that Gmail is profiling you and surveilling your email. The cost of a commercial privacy-centric email provider is about $50 per year, a trivial amount for the average US-based Hacker News reader, much less than going to a sports event or concert. So why are so many technically-sophisticated and privacy aware people, even here on Hacker News, still using Gmail? I'm not convinced that it's due to Gmail's superior spam filtering. It's been my experience that the spam filtering on commercial email providers work just fine.

SEEKING WORK. Embedded Software / DSP / Test Automation / Code Rescue

I can bridge low level and high level work.

I travel frequently between Kalamazoo, MI and the Leuven/Brussels area, so remote+visits preferred. CV and contact info at http://zwizwa.be?hn

Currently looking to fill a small gap (weeks). I'm a quick starter.

Looking for a longer term 50% FTE commitment as well.

Past and current projects are mostly in the field of embedded systems: ASM, C, C++, Rust, on bare bones uC, RTOS and Linux, various architectures. I've ventured into simple analog circuit design and FPGA work on ice40, but my main field is software.

I do code rescue, code cleanup, prototype firmware refactoring. If you're familiar with embedded software you know what this is about.

Apart from the low level exposure, I've had a good dose of Functional Programming in the last 15 years. I use Erlang on embedded Linux, and Haskell and Racket for validation and code generation.
I remember when I was a kid in China, school showed us a clip announcing the man stopping the tank as the 'robber' who was trying to rob a tank. I was like wtf you got to be kidding. I was like 12 and I felt that my intelligence was insulted... that's probably why I no longer live in China.
A lot of those SaaS end up with end users dumping data down into Excel at some step, but they definitely can be wins for workflow standardization and error reduction versus trying to do it all in Excel.

Has anyone else read Lee Smolin's new book, "Einstein’s Unfinished Revolution: The Search for What Lies Beyond the Quantum"?

It provides an excellent overview of how quantum physics got hijacked by Bohr, how Einstein's realist views were stymied by his inability to let go of locality (and how this is understandable because he depended on locality to develop relativity theory, and the fact that he died before experiment demonstrated quantum non-locality), an overview of realist interpretations (and their drawbacks!), and a direction for future research.

> Even with all the annoyances I found when working from home I had a lot of trouble “stopping” — it felt like I was always at work.

I'm curious because I never had this problem...

Did you have a dedicated computer & desk for work? Did you have a work room?

I started without a work room, but I got a work laptop & desk with none of my personal stuff on it; and none of my work stuff was on my personal devices. I put these in the kitchen where I don't normally hang out much. Once I'm done working, I go to another room where most of my personal life is. I never had this feeling that I'm "always at work", and work/life balance got strictly better than it ever was with any commute.
or, alternately, buy out the entire media and claim that the global level of implicit spin injected into everything is 'objectivity'...

this is a 2 edged sword which cuts both ways
Yeah by making your own counter-message, you're being humble with respect to that possibility. Let there be two propagandas dropped at the same time and hopefully the truth will tip the scales.

So the biggest impact would be cutting dependence on coal rather than a few hundred people (or even a few thousand people) giving up on air travel.
I think it is actually preferable to start by converting categorical variables to numeric most of the time, even if they are not ordinal. The RF algo can separate off individual classes with 2 splits (e.g. <=7 then >=7) if a single class is very important. The "pool" of features for RF sampling also doesn't get diluted with one hot encoded classes from the one feature.

I am pretty sure I've seen this done successfully in kaggle a bunch before, but don't have any sources on hand for evidence that this method is "better". It does however make it much easier to just throw the data into the RF and check the feature importances to see which features are helping the most.

> cut ties with the former, and engage solely with the services of the latter, then no one's going to accuse you of tax evasion either.

If your worry is that an existing government will allow some rich people to register as living on seastead and not pay taxes, then this doesn't have anything to do with seastead, and is only a failure of the government. If US allowed such a scheme there would not be any need to build a seastead, any corrupt government in any small country would be happy to provide all that is needed for a fraction of the cost.

On the other hand very similar thing is already happening in places like Russia where families of many government officials live in US and Europe using the money stolen back in home. (One city mayor even got a US green card requiring to live half of the year in the US, at the same time keeping his post and giving speeches on how bad is USA).

> because there are whole lot of background, foundational services that they provide the people seem to like to pretend simply appear out of thin air.

That is because the services that governments provide are bundled, which makes it hard for people to see what is the foundational service they are paying for and which is something that no one wants but has to buy because some bureaucrat 50 years ago managed to pass a law. Experiments with seastead governments would help to make the bundles more explicit.

I meant that while my country was quite fucked because of USSR, it would be completely wiped out without it. [1] I brought up Auschwitz specifically because it was the Red Army that finally kicked Germans out of there (only when it was convenient, but still).

[1] I know people IRL who claim Poland should have teamed up with Hitler against USSR and then double-crossed him, but I have doubts it would work.

EDIT: I re-read the above conversation, and I'm still not sure how did I end up defending USSR in the name of a discussion boiling down to "do you prefer plague or leprosy?" I don't think we really disagree all that much, so I'm out, thanks for conversation.
I’m privacy aware, but I just don’t think I care. So many things that I’m suppose to be outraged about.

I’m exhausted.
