Those who tend to advocate for Free Speech have a very different concept of what free speech encompasses compared to those who advocate for hate speech based restrictions on speech. While there are sound arguments in both camps much of the discussion online is cross talk with each side misunderstanding the other.
It does, otherwise the laws against hate speech wouldn't be 'limitations of free speech'.

The statistical difference between 25,000 and 43,000 samples being... small. Basically, any effect visible at less than 2 in 40,000 might be missed by the 25,000 test.

A problem is not something to hide, it is an occasion to show your strengths.

It always seems silly to me that companies try to hide some kinds of problems that just inevitably pop up at companies of large enough size. By trying to hide a problem they usually expose themselves to risk of much worse PR disaster and loose occasion to come transparent about the issue and even gain points with customers for resolving it.

Also, this lesson is not just for companies, this can also be useful personally, very effectively.

I have also noticed that probably Europe and the US vote somewhat differently on at least some of my comments. But I think that's a separate pattern from the tendency for some of my comments to be immediately downvoted and then voted back to neutral.

It tends to be certain kinds of comments and unlike almost everything else about HN, I am usually not surprised by that pattern because I tend to expect it for certain topics or certain types of observations that I sometimes make.

I have a really poor ability to predict which comments of mine will do really well.

The tests are for disease. We hope it protects against infection/the ability to spread it. But that's not part of the testing

I don't know how many existing vaccines fall into either category here, i.e. whether there are many vaccines that prevent disease but do not even reduce the ability to spread. Would be interesting to know.
As I understand it, whatever gets us to herd immunity more quickly is the best solution. That probably means a mix of both heavily tilted to the Oxford one.

This vaccine is cheap, 90% efficient and easy to get people vaccinated. The other ones are expensive, 95% efficient and difficult to get people vaccinated.
Nope that means I care about Apple platforms and UNIX, not pretty replacements for GNU/Linux.
I agree. If it's not actionable, then it's just adding to the doom. But not all of it is not actionable. And you definitely can't take actions based on information you don't have. Even just telling your friends about it is arguably action, because while it's not actionable to you, maybe it is to them, or maybe it's something you can take action on as a group.

Obviously finding a balance is essential, so you can be well informed and reactive, but also not drown in doom. I'll admit: it's a balance I haven't found, but I firmly believe living in a metaphorical hole isn't going to make anything better.

I rather like Angular but got burnt by the constant updates. Angular versions get bumped then the components you're using don't keep up so you drop them. Oh there is a minor syntax change, I'll fix that up. Ah best practices say I shouldn't do this anymore okay I'll change that. Oh look no time left to add features.

The reason for much increased competition is the slow population growth rate. If government policy dictated that population should be increased, then we could have good times. They wont come until then, and the path forward is space colonization for good times again.

When the population doesn't increase as fast or starts shrinking, there is going to be emotional unhappiness. I know why, but the subject is sensitive to be discussed openly.

The other option for increasing happiness is manipulation of the birth rates/ratios with mandatory genetic modification/engineering. Then people will be more satisfied, while having a shrinking population across the world.

Growth in populations masks many problems therefore results in happiness. A decline in population increases unhappiness and exaggerates a problem.

But the problem is that a larger and larger percentage of population isn't going to get their needs met when the population starts shrinking across the world. There needs to be a mandatory global order for genetic modification.
You probably haven't written modern JS. Since ~2016 (ES6) the language is basically completely different and really concise now; consider ES5:

function increment() {
var out = []

for (let i of [1,2,3,4,5]) {
out.push(i + 1)
}

return out
}

vs ES6:

const increment = () => [1,2,3,4,5].map(i => i + 1)

etc. Most people's experience with JS/TS has simply been before ES6 (which had massive problems, like `var` and `this` scoping etc.), it's really nice nowadays.
Honestly, I think it's part of the solution. Too many words are spent in online arguments between two people who aren't at all open to changing their beliefs. If people are willing to admit that at the outset, everyone's time is spared.

"You happened to find a decent Lexus dealership - maybe somewhere else there will be an equally nice Volkswagen dealership."

The margin on a VW isn't as high and costs significantly less on average than Lexus, so independent dealerships selling VWs have to operate on volume instead of long-term reputation and relationship building. The VW shops will be nice but don't have the time or budget for all the extra.

"Everything you described depends 100% on the individual dealership not on the brand."

This isn't the case. Just like different luxury-leaning domestic brands in Europe have levels of corporate ownership or incentive to provide certain services, leading Lexus also has what I assume is an incentive program for dealerships to offer different levels of lush care: https://www.lexus.com/guest-experience.

There will be outliers but the trends and reputations exist for often explicit reasons.
Your comment reminds of something Douglas Adams once said:

>> * In this century (and the previous century) we modelled one-to-one communications in the telephone, which I assume we are all familiar with. We have one-to-many communication - boy do we have an awful lot of that; broadcasting, publishing, journalism, etc. - we get information poured at us from all over the place and it's completely indiscriminate as to where it might land. It's curious, but we don't have to go very far back in our history until we find that all the information that reached us was relevant to us and therefore anything that happened, any news, whether it was about something that's actually happened to us, in the next house, or in the next village, within the boundary or within our horizon, it happened in our world and if we reacted to it the world reacted back. It was all relevant to us, so for example, if somebody had a terrible accident we could crowd round and really help. Nowadays, because of the plethora of one-to-many communication we have, if a plane crashes in India we may get terribly anxious about it but our anxiety doesn't have any impact. We're not very well able to distinguish between a terrible emergency that's happened to somebody a world away and something that's happened to someone round the corner. We can't really distinguish between them any more, which is why we get terribly upset by something that has happened to somebody in a soap opera that comes out of Hollywood and maybe less concerned when it's happened to our sister. We've all become twisted and disconnected and it's not surprising that we feel very stressed and alienated in the world because the world impacts on us but we don't impact the world. Then there's many-to-one; we have that, but not very well yet and there's not much of it about. Essentially, our democratic systems are a model of that and though they're not very good, they will improve dramatically. *

That option might not be available in the short term. Spain for example aims to vaccinate almost the whole population until summer 2021. What are you going to do when you don’t think it’s version X.1 yet?
Correct me if I'm wrong but they ran 2 tests, and if you give someone a half a dose, wait a while then give a full dose, it's 90% effective?

So calling 70% is inaccurate?

The problem with adenovirus vaccines is that body might build immunity against the adenovirus as well. So, you give one jab, adenovirus infects enough cells and creates enough antigens, immune systems notices and does something about it, but it also notices the adenovirus and makes antibodies against that, too.

With the second jab those antibodies immediately neutralize the adenovirus so it can't infect enough cells and make enough of the COVID antigens so the protection is not that strong.

The Russian vaccine avoids it by using two different strains of adenovirus for the two jabs
simply put, most of these are first world problems.
My understanding (which might very well be ridiculously wrong) is that mRNA vaccines are a bit like 3d printing; it is incredibly faster and cheaper to build a single one-off item, but if you need to mass produce you still want to go with injection moulding.

An aesthetic benefit to placing the ThinkPad bricks strategically around the home is that you can mount them in a way that's more tidy when you're using it, than dragging a brick around. (Though there can be an aesthetic downside to having a cable around when you're not using it.)

My favorite means of mounting a brick is to use a large pair of Velcro. For undersides on some IKEA tables, I once had to augment the Velcro pad adhesive with Gorilla Glue. Sometimes I use zip ties instead of Velcro.

When buying extra bricks, in addition to the presumed-good one that came with the laptop, I advise going to some effort and guesswork to try to get genuine, non-counterfeit ones. I've seen some corner-cutting in circuitry in other power adapters and chargers, and that seems like a fire hazard.

For people who don't like the idea of bricks plugged into the AC when not in use, Leviton and others make little switches that plug into the AC outlet.

So to censor your opinion, I just have to justify it as hate speech. A slippery slope if I ever saw one.
I thought adenoviral vaccines were also relatively new. Not as new as mRNA which is bleeding edge, but still i think this would be the first time this technique would be approved for human use should it be approved.
I would imagine that organisations like this would tend to back riskier research that would struggle to get funding elsewhere. It may be that they back a wide variety of early stage trials, most of which go nowhere. There is a list of funded studies, which is excellent.

The thing with the EU is that we have variable, externally controlled infection rates. We could eradicate it, but there's no point because we have land borders to countries we can't control. So we're just trying to keep local rates below crippling. (With mixed success.)

The point of a vaccine is that you can't scale it back for populist appeasement; once you have broad immunity you keep broad immunity for long enough that you end up eradicating the virus almost involuntarily. In comparison, a lockdown is much more vulnerable to feel-good measures reducing the effectiveness.
I don’t think the “don’t bother responding” part is productive, but I also think we have to avoid false equivalences, pretending both sides are anywhere close in terms of how much they’ve misbehaved (not saying you’re doing that, but a lot of people are in an attempt to stay above the fray). False equivalence is how the frogs got boiled and we ended up where we are today.

Most of the stuff in the article I already know but it's still nice to have a document that you can point folks to who aren't familiar with these things. I think one interesting point from the article is that CVS is from the 80s, SVN from the 90s, and git from the 2000s.

The past decade had no major VCS show up, but rather was characterized by the success story of git replacing everything else. Gcc's and LLVM's migration to git isn't that far in the past at all. So I wonder, as the last decade lacked a major leap in VCS technology, can VCS be considered a solved problem now?

I recently read on hn a comment saying that Linux will be the last OS. Is git the last VCS?
There's always a useful idiot.

From my perception it’s not that easy. Recently there have been research papers released that estimate long term effects also with children comparable to young adults.
For the sake of argument, let’s assume they are right and that we know that COVID-19 has significant long-term risks for children. How do you outweigh that against the uncertainty of risk of the vaccine?
Or you know, maybe Europeans and Americans just have different cultures and values.

Does anyone have a pointer on how the mrna vaccine actually works? I understand basic genetics mechanisms and how mrna works inside cells. In shot form, I assume the modified mrna strands are floating through the blood stream. What happens after the injection?

Btw .. I think public health needs to start educating people on how these things work in order to get high coverage. I am alarmed at the number of highly educated people I know who seem suspicious. This fear is just borne by a lack of understanding and can be corrected IMHO.
Yes it does. In the US free-speech does include hate speech.

Even in countries where there is hate speech, what and what doesn't constitute it is normally broad, subjective and is frequently misused by state to prosecute people that have no ill intent.

The most egregious example is the Chelseas Rusell case in the UK:

https://www.liverpoolecho.co.uk/news/liverpool-news/woman-wh...

Also not only that but it doesn't work. If you stop people from saying certain words they just end up making new ones to get around your censorship. It is already happening online, people will make up new words to get around any speech censorship e.g. "jogger" means black criminal and I will leave it up to you to work out what that is being used in place of.

Also banning certain words doesn't take into account regional dialect e.g. Faggot is a regional dish in England. They recently banned google ads for a restaurant that sold "Fanny's Faggots".

https://www.dailystar.co.uk/news/cafe-advert-fannys-faggots-...

Or this curious case that I just found while looking for the previous one:

https://www.dailymail.co.uk/news/article-7911927/Meat-lover-...

Hate speech legislation doesn't work and just causes people to start resenting law enforcement and have less respect generally for the laws of the land.
Many forget that modern microcontrollers are much more powerfull than 16 bit home computers, and that is where I started with C++, had C, Turbo Pascal, Turbo Basic, QuickBasic, Clipper, Lisp, Prolog, Forth,.... at my disposal as well.

Sometimes reading comments about what microcontrollers aren't able to do in 2020 looks like cargo cult of people lacking the experience of how it was like to code with 640 KB.
Yeah, this seems to be an average of 2 different dosing regimes, one of which was 90% effective.
From the article:
"There is also intriguing data that suggests perfecting the dose could increase protection up to 90%."
Note that only n=2,741 people received the 90% efficient dosing. That's 10+ times less than the mRNA vaccines so the confidence intervals on that number will be a lot wider
>At $3 to $4, many countries will jump on board ASAP and stay away from the expensive vaccines from Pfizer and Moderna.

The price difference will likely remain substantial, but in case anyone is unaware, the difference is currently greater due to AstraZeneca pledging to the sell the vaccine at cost "during the pandemic", while Pfizer and Moderna have indicated that they fully intend to profit. [1]

Once AstraZeneca deem the pandemic to be over, the price will likely rise.

It was reported a few months ago that internal AstraZeneca documents showed them projecting the "Pandemic Period" to end on 1 July 2021. [2]
