I wrote a Ruby gem to address this problem of hiding sequential primary keys that uses a Feistel network to effectively shuffle int64 IDs: https://github.com/abevoelker/gfc64
Kinda similar idea to this library but you're encoding from an integer to another integer (i.e. it's format-preserving encryption). I like keeping the IDs as integers without having to reach for e.g. UUIDs
I recommend to review my comment where I also use a Feistel cipher [1] but the difference is that it is not limited to int64 but I can even use 8 bits. Obviously loosing security properties but working as an obfuscation method. If you use a random source with relatively few bits you should check if there are duplicates while with the Feistel cipher you are sure there isn't.
It's really an indictment of how far HN has fallen to Redditification* that you see this kind of low-brow ignorance so prevalently and so often.
Yes, the greedy doctors who are lucky to get a couple hours of medical coding training when they start practicing and get needled constantly by their billing department for underbilling actually have "years of learning" in how to screw over their patients.
Maybe they mean the man-years of time wasted arguing with insurance companies, shuffling around medications and care plans to please them, evenings and weekends spent in the EHR finishing up patient notes (because there's no time to get them done during the working day with 20 minute visits) and correcting and signing off on patient care for the PAs and NPs (cold-heartedly taking 100% of the malpractice risk burden for the nurses who actually care about "healing").
I'd encourage people this far gone on the deep end of visualizing physicians as hand-rubbing greed machines to spend a day actually shadowing one. Because you are very ignorant about how they spend their time and the amount of effort they put into caring for patients in spite of continual soul-crushing roadblocks put in their path.
* Yeah I know it's against site rules to say but I don't care it's true
I don't get the vitriol or where you assume I see doctors as "greedy" or determined to "screw over their patients". I assume you've read a lot of stuff here that gets under your skin, and that my post somehow reminds you of those. But you read a lot of things into it that I didn't write and wouldn't write.
Doctors are brilliant individuals and often deeply invested in patient care. Many if not most of them pursued the career because they wanted to be healers. But as you beautifully describe, a lot of their actual job is now committed to navigating endless bureaucracy because they are the only people who have been institutionally blessed to do so. Given that many of them do care so much about patients on a personal level, and pursued the field for that reason, it's tragic that paperwork takes so much away from their opportunity to do so.
My perspective even goes so far as to argue that their pay isn't a product of greed at all, but simply a necessary outcome of institutionally mediated medical goods, of which they've been tasked as front-line guardian, being grossly expensive. Reduce the cost of what they control access to, as we see in non-US health care markets, and their pay naturally reduces.
In lieu of that, the US solution is to cleave out the responsibilities that don't require 8+ years of education and residency to get right and allow them to be dispensed by others.
There's no indictment of doctors here, friend. None at all. It's all just mechanisms in a system much much bigger than them, and these mechanisms (as you describe!) frustrate them at least as much as anyone else.
A redditor made a gif Trump hitting CNN with a chair in a wrestling ring, or something to that effect. It was subsequently tweeted by Trump. CNN tracked the gif back to the redditor that made the gif and threatened to go public with his identity and reddit comment history if he didn't issue an apology (which he did).
I think the lesson is something about picking fights with people who buy ink by the barrel.
It was investigative journalism, if you can call it journalism. CNN investigated the origin of the gif, and used biographical details revealed on reddit to determine the gif creators real name / identity. They didn't ruin his life, but threatened to go public with information which probably would have.
Private companies still have boards of directors. It's possible to have a board of directors with only one member but this is a rarity; even non-profits and pre-funding startups will usually have a board with more than one person.
> It's possible to have a board of directors with only one member but this is a rarity
It is actually extremely common for corporations which aren’t regular business as such - for example, trustees of family trusts are commonly corporations with a single director who is the person who ultimately controls the trust. Also a common structure for sole proprietorship businesses that want some protection from legal liability.
I own a company which never has done anything (I was daydreaming). Its board of directors has one member-me. Legally, I am required to hold annual board meetings with myself, although I believe the legal obligation is met if I hold them in my head. “This year’s financial results: zero revenue, zero expenses, zero assets, zero liabilities, zero employees-another great year at does-nothing-corp!”
Minutes would be important if my company actually did anything. A company that literally does nothing doesn’t have to worry about the piercing of the corporate veil, because you first need to do something before you can become liable for it
I'm a little confused by this comment because a sole proprietorship cannot exist in the form of a corporation. Of course, one person can have a corporation all to themselves, but the definition of a sole proprietorship is a business without a more complex form.
I'm guessing what you actually mean is "Also a common structure for one person who does business on their own, who has incorporated, and who is their own sole board member." Is my inference correct?
What I mean is a person who has a sole proprietorship desires greater legal protection, so they set up a corporation to replace their sole proprietorship, but it is still just a one natural person-owned business-in legal terms it is no longer a sole proprietorship, but in non-legal terms nothing has changed
This is common in the US too, usually they need to file with their state. Going private will often remove the need to file publicly with the SEC though (though even then, that depends on things like how many shareholders there are, not the trading status as such).
All companies have boards of directors, even privately owned ones
Small firms it is common to have a single person board of directors, where that single person is the 100% owner.
When private equity takes a large firm private, they’ll often appoint a board full of their own partners and consultants/advisers-if you own 20 different firms, you don’t want to deal with all their CEOs, you want a layer between the CEO and you-which is where the board helps.
100% subsidiaries (such as a large multinational firm’s local subsidiary in each country) commonly have multi-person boards of directors, with a handful of local senior staff on it (e.g. country director, head of local finance, HR and general counsel) - they usually all just rubber stamp whatever HQ wants, although occasionally they might refuse (e.g if local counsel insists HQ’s demands are illegal and complying with them would make the directors personally liable)
It depends on the country. Where I live (Australia), we don’t have “LLCs”, we do have “PTY LTDs”, which are like an LLC - but it is a corporation and all corporations have directors, although the majority of PTY LTDs are sole director sole shareholder. Here, all companies are corporations
I should point out that in the traditional legal sense of the term, even US LLCs are corporations-it is just that people in the US have adopted some weird redefinition of “corporation” which excludes them. Under Australian law, a US LLC is a corporation, albeit a foreign one. Worldwide, I think most countries legal systems would reach the same conclusion
The British monarchy is a corporation (a corporation sole) - actually, a whole bunch of distinct single member corporations (the monarch), one for each Commonwealth realm, and also one for each Australian state and Canadian province - each called “the Crown in right of X”. Maybe that’s an example of a corporation without any directors, although one might (rather meaninglessly) claim the monarch is the sole director
This is absurd. You are citing computer models that assume no geography and random mating. The MRCA is around 150,000 years old and probably from east Asia, and the identical ancestors point must be older than that and originating in Africa.
When a sentence starts with “given the false assumption…” it is best not to adopt the conclusion as a fact.
I think this is right by the other propositions in the wiki articles, but was surprised to find out we don't know the MCRA.
"The age of the MRCA of all living humans is unknown. It is necessarily younger than the age of either the matrilinear or the patrilinear MRCA, both of which have an estimated age of between roughly 100,000 and 200,000 years ago."
"The identical ancestors point is a point in the past more remote than the MRCA at which time there are no longer organisms which are ancestral to some but not all of the modern population."
So the MCRA is < 100kya, and IAP > MCRA, so 100kya > IAP > MCRA.

Take heart, even if you weren't shadowbanned, with a young, low karma account your first comments on most subreddits would get automatically modded as spam by Reddit's dumpy spam filter anyway.
As a primarily Ruby dev I'd prefer the AI/ML ecosystem not be split-brained between two languages that are semantically 90% the same thing. Just learn Python and integrate the models into your Rails (or whatever) apps.
