> Covid-19 causes brain damage in children

Boy is this editorialized, did you even read your own study?

> Conclusions and Relevance In this study, many children and adolescents hospitalized for COVID-19 or multisystem inflammatory syndrome in children had neurologic involvement, mostly transient symptoms. A range of life-threatening and fatal neurologic conditions associated with COVID-19 infrequently occurred. Effects on long-term neurodevelopmental outcomes are unknown.

1. this is among survivors of severe covid. The cohort of under 21's that get severe covid in the first place is extremely low.

2. symptoms are described as "mostly transient".

i.e you're not getting brain damage from casual covid, which is 99.9% of cases.

Even your lancet study shows for non-hospitalization cases, the "cognitive decline" is under SD=0.1 which is arguably within margin of error.

Concerns about the efficacy of cognitive aptitude tests notwithstanding. [0]

asking you for time before your start is iffy, but everything else seems an overreaction.

it sounds like a growing startup.

it's probably really hard to move start dates or cut 1099 pay to soon to be employees and if they were picking the tool i'd be using for the next 1-5 years, i'd probably want to sit in on that as well.

you will probably have to be clear to establish boundaries all around, but that's likely the case with any growing company.
That means to irritate but guess he meant exonerated.

> Also everyone seems to forget that the history of unions in the US is inseparable from mafia racketeering.

This is disingenuous, because the sort of unions that were involved with racketeering were manufacturing unions, specifically the Teamsters, and overlapping a period during the late 19th century where corporations often employed actual violence (with paid armed security squads) against workers who attempted to organize.

Both were wrong to engage in criminal behavior, but the incentives to do so were pretty strong. Furthermore, because the workers for these industries were drawn from largely impoverished communities where low-level organized rackets were practically a necessity for survival, it's not at all surprising that the relationships and methods continued into the workplace.

There is, however, no history of mafia racketeering with teachers or nurses unions, and regardless of one's opinion about tech worker unions, there is no reason to think that they would have any affinity for organized crime outfits.

Does this refer to contractors?
Instead of the government, we let corporations repress deviants.
I have my own version of "Bill Gate's" quote , "640K Ought to be Enough for Anyone". An i7 with 16GB of memory ought to be enough for anyone. "Anyone" in this case is the typical office worker or home surfer. Gamers, devs with a bunch of VMs, data scientists, no, but the vast majority of people surfing and running Office? It's enough.
Let's say you have two dependencies each requesting colors:

colors@1.0.1-1.0.3

colors@1.0.1-1.0.4

With npm, you'll end up with 1.0.3 because it satisfies all constraints. OP wants to end up with 1.0.4 if at least one dependency tested with 1.0.4 (and reject 1.0.5). I don't know of a way to do this with npm today.
What you want is available today, in all major browsers. Yes, very viable IMHO.
Could you please tell me how to avoid ever using your code ?

We (US) are at 850k. No way India is doing better than us per capita.

The Omicron new cases reported surge on worldometers is up to 800,000 new cases PER DAY, this is more than 300% higher than at any point in COVID ever.

The death curves trail the new cases by a bit, so we'll see. But holy cow is something up. I really really hope Omicron has substantially less mortality.
This is a fascinating twist to me. Human exceptionalism is what lets us justify not eating other animals- if we're not special then there is no reason we should be held to a different standard. I have encountered many conversations with the opposite premise and it never occurred to me that it should be reversed. Thanks for the new perspective.

I just think that it's difficult to have the foresight to know whether something is good or bad. Perhaps if we allowed bitcoin mining in some regions and disallowed it in others, then mining energy usage would decrease on a large scale and we could also see if it were beneficial or not.

I'd like to see this on a national scale instead of an international one (which is already the case) so that you wouldn't have to move countries to simply evade a law, which is a very arduous process.
awesome, we might consider YC after all
That's a great question. The only author I've ever read that I think comes close to answering your question is a pseudonymous author called "Alone", who wrote the blog The Last Psychiatrist.

Here is one article relevant to your question:

In short--to stop suffering from extreme negative thinking, you will need to change your life. To change your life, you will need to live differently. However, living differently is harder than being unhappy. It will always be much easier to endlessly introspect about why you're unhappy than it will be to do the work of changing your life in order to live differently.

Good luck. I would be happy to send you some other primary sources that helped me in my life; my email is in my HN profile, but I may not have had the unique problems you have and could just be another dud.

(The only shot-in-the-dark tip I have for you is to stop hanging out and trusting dishonest people. It is not always easy to recognize when someone is dishonest, but once you've figured it out, don't make excuses to keep trusting them.)
YC has to react to VCs entering early stage investment. Accel in India grants upto $250K to startup founders (no strings attached) [0], while Sequoia seeds select startups with $1M in capital [1]. In India, $250K's roughly worth what ~$4M would be in the US.

Just to put the amount in perspective: Our team of 3 engs in India got a generous $12K grant from Mozilla in June 2020, which has kept lights on our toy project for 2 years now. I think we can stretch that budget to 3.

YC $500K is a total game changer for startups overseas (esp in countries with lower cost of living).

Well we do have laws against openly bribing lawmakers.

Lobbyists aren't handing over wads of cash, they are spending money on things like ad campaigns, surveys, studies, talks, busing people in to talk to their representative, etc which are meant to legitimately sway the opinions of both the elected officials and the electorate. Maybe to get more politicians to show up the lobbyists pay to serve nice steak dinners at a talk, and in the extreme maybe the talk is just a thinly veiled guise for what is really an expensive gift of steak dinner, but conceptually it's no different from any other potential catering option, and there is no simple way to ban it. Sure you can make specific schemes illegal, but there will always be another loophole. So long as you allow people to interact with their elected representatives and speak freely, there will be people who have their politician's ear. You might be able to eliminate lobbying by sequestering the politicians throughout their term, but that's going to have the opposite of the desired effect of making government more democratic.
Late, but thank you very much for the detailed response.

"See, the issue is there. Don't have time? Ok leave the issue open, it acts as a documentation about, well, that there is an unsolved issue."

I think this is really important. In some projects, the number of open issues is always zero. Most people see this as a good thing. I think it is not. we need projects where there are hundreds of open issues and these issues are visible. it is important to solve problems if they want to be followed clearly. I think it is a very important issue to be able to follow up the problems clearly.

> it's as easy as keeping "no FITNESS for a PARTICULAR PURPOSE" as a mental mantra

It definitely is. Of course OSS authors and maintainers want to see people using and enjoying it, but nothing is black or white.

What you really mean is that you want people using and enjoying your software within the limits of time and abilities that you can employ on it without it affecting your mental health.

Some people are worse than others at finding out about this latter part, and as a consequence they suffer.

My point of view is that if you don't care as default state, then you put work into actually caring, when you get to your limit you'll be able to very easily see that you cannot contribute any more hours today, because you're almost depleted how much you actually care. Thus avoid crossing that thin line that is burnout and all mental health issues that come with it.

I.e., be in a defensive mental state. Ironically, it will make you work happier and over a longer period of time, which ends up being positive for the health of the project itself.
There are things beyond compensation that individuals cannot easily negotiate by themselves. For example, a reasonable ask could be to never get contacted by boss or work colleagues (about work) outside of work hours (unless oncall, etc.). In the absence of group coordination that a union provides this work arrangement is simply out of reach for most.
Everyone has some non-orthodox beliefs. I am sure I'm not exempt.

I'm not trying to describe someone who has a few odd beliefs, especially if they know they are a bit odd and can entertain good arguments.

I'm trying to describe where someone descends into the whole web of inter-related beliefs and accepts them with a religious determination, resisting even the suggestion they could be wrong.
The choice to use SHA256 is surprising to me given that there are a number of other hash functions such as the BLAKE family that are explicitly designed to have arbitrary output sizes.
If you don't like how some open-source library is managed, then exercise your freedom to fork it. Anyone who then claims that they don't have the time or energy to maintain such a fork cannot also reasonably expect anyone else to spend their own time and energy maintaining it for them.
Interesting read. I realised about halfway through that it felt exactly like an Adam Curtis documentary.
I think YC is great for founders (I actually went through a batch many years ago), but it's worth mentioning many of the startups are not really that early. Some were going straight to an A round instead of a seed round, many (maybe most) had already raised money, some had already raised money at significantly higher valuations.

The advice I give to 99% of people is if you get into YC you should definitely do it, but the valuation is not necessarily high.

At least in my mind, "consumer product" quite clearly implies that the price is advertised, or at least easily found. And it does not change during the transaction.

Which is definitely not the case in American health care - unless you have "For the Top 1%" health insurance, or are buying at the bottom end (a bottle of aspirin, maybe an eye exam or dental cleaning).
work has already begin on a direct-style IO library that internally uses effects. See:

- https://github.com/ocaml-multicore/eio#readme for more information on the Eio library
- https://watch.ocaml.org/videos/watch/74ece0a8-380f-4e2a-bef5... is a short talk on experiences using effects with some nice motivating examples

Note that Eio is more than just a direct replacement for Lwt and Async. We couldn't resist using some of the experiences also gained from the MirageOS (mirage.io) unikernel framework in EIO. This means that the backends are highly optimised to use the best syscalls available in the OS (e.g. io_uring by default in Linux). If you write your applications to use Eio natively, then performance is very high so far. The ergonomics of programming in it also compare favourably to using monadic concurrency.
> I slightly fear how much of my own thinking is there just because some corporation or another big entity wanted me to think like that and spent considerable resources to make it happen.

Now consider how much of the thinking of the people who believe the opposite is there just because some other big entity wanted them to think like that and spent considerable resources to make it happen.

The one thing you can't outsource is critical thinking. Sorry, you have to do it yourself.
Roughly: The additional converts at the best deal another investor gets at/before the next priced round.

If the next priced round is at $7.5M, their $375K converts at that price (so it buys them another 5%). If your next round is not above $1.8M, it’s already an unfavorable sign.

The only downside I see is it doesn’t let you raise another small amount without valuing YC’s follow-on $375K. You might want to do such a raise for strategic rather than financial reasons and this would be an overhang against that. (I don’t think it’s that big a deal in practice and the additional committed money is probably better by way more than this detriment.)
Are you sure this is how it would work? From the post I read the remaing 375k will be invested at the next equity round.
idk canada has 806 covid deaths per 1M and usa has 2573, it's not exactly screaming 'success story' to me.
Two things: saying no to the majority of time requests (it used to be very hard for me, but now I realize the power it gives me over my own time), and focusing on one task until it's done (I have a few Trello boards and have gotten more religious about 'WIP' during my working hours... though I probably hang out on HN and Reddit a bit too much still).
Bitcoin dwarfs the electricity usage from the US Mint, the literal money printers.

The US Bureau of Engraving and Printing has a $1 Billion budget for manufacturing.

https://home.treasury.gov/system/files/266/24.-BEP-FY-2022-B...

How far down the rabbit hole do you want to go? No matter how you look at it, Bitcoin is horribly inefficient. Compared to the US Dollar (the literal physical dollar), credit cards, banks, or other institutions.

Mind you: Coinbase is _NOT_ part of the bitcoin mining network, despite being a "bank" or "exchange" that processes a huge number of bitcoin transactions. Even when we ignore the electricity costs of Coinbase (and other servers), the BTC electricity usage is colossal.

That's more true when taken in isolation, but I read about it as part of "Extraordinary Popular Delusions and the Madness of Crowds" by Charles MacKay as illustrative of crowd manias, mob mentalities, town scares and herd stampedes, not necessarily as great financial disasters in history. There are plenty of those that didn't involve the madness of crowds.

Freedom (or possibility of) for women, at least in some sense from their spouse/family.
Going by my memory, when YC started they invested 5K per founder. It was, either by accident or design, focused on 20-somethings eating ramen and dreaming big. You could not do much else on 5K.

There may have been many (myself included) who thought "give up a cushty job, and even if I get in, don't get back much more than the cost of flights to Boston"

Does this signal that its harder to find those young hungry geniuses? Or that other stages of life are now predominating?

I would be fascinated to see a demographic breakdown of YC / SV founders ...

Edit: the thing is it breaks my clever idea of A Million Startups. So i had a clever idea a while back, (I think when Softbank wrote off 10BN?). 10BN is about the right amount to fund a million startups. 100K in India, 100K in SE Asia etc etc. You could assume a 50% fail rate at each "stage" and put in 5K to each of a million startups, and then 2.5BN, then 1.5BN etc etc. I am not sure what kicking off a million bright young things would do to the world, but I think it is a worthwhile way to waste 10BN
You're severely underestimating the power of collective bargaining. A good union will advocate for you even if you don't do anything. It removes a lot of the secrecy, ambiguity, and work when it comes to getting the maximum value out of your employment. Too worn out or anxious to keep pushing for a raise? the union's got it. Issues that you would never mention to your boss as an individual for fear of retaliation? the union's got it.
