I don't know if the site was better, but let's say it was; it was also smaller. The same tactics don't keep working as a forum grows, so your argument is actually for letting it destroy itself, be garbage-collected by the big VM in the sky, and get replaced by newer forums which spring up, thrive for a while, and become scorched earth in turn. That's the cycle of life on the internet, but the idea of HN has always been to try to stave that fate off for longer. In 2013-14, the last year before we started moderating the site in the current style, the system was under so much pressure that there were signs of it being about to break—and in fact it did break, because the person who created it couldn't take it any more. It was an awful experience.

I definitely want to find ways to become less visible if possible. I don't much enjoy writing tedious and stupefying moderation comments, getting swarmed by wasps, accused of every bigotry, and reliving the same thing the next day. To be visible in such a role is to be the receptacle for a lot of people's anger about completely unrelated things, and you cannot expect them to treat you with scruples. That's only a tiny minority of the community, of course, but the community is large enough that it's still a lot of people—more, say, than one knows personally in life. On the plus side, one gains appreciation for Samuel Beckett as a spiritual teacher.
> [..] didn't seem interested in our fixing our complaints without a massive amount of money [..]

Why is asking for money wrong? You want the feature, why shouldn't you pay for it.
It really was not. 'dang and 'sctb have done yeoman's work in establishing a tone for what's acceptable--and they have put a lot of thought into things; I occasionally email hn@ycombinator.com with a "hey is this actually cool?" and while I don't always agree with their conclusions I'm always struck by how well-considered the results are.

HN is full-stop better than it was.

> I’ll trust the experts who went to school and have ongoing training to educate my kids. That way I can focus on being a parent.

Your duty as a parent is to educate your children. Why the hell would I trust the government to not indoctrinate my children?

It is truly sad that many parents wash their hands of raising their children by passing them off to the government to be educated.
This is because the advice was delivered in a hare-brained manner and a month late.

It should always have been a combination of mask wearing from day 1 and stopping any large gatherings. Combine that with social distancing and you get most of the benefits. Now we have already infected so many people and are trying to close the barn door when the horse has long fled.

Before the lockdowns people were going about their merry lives WITHOUT masks. If they were doing exactly the same things but WITH masks, we would still be better off.

A coordinated advice in this case is important. Without a central authority advising for masks, people who do choose to wear them look like loony conspiracy theorists, but if there is central guidance for doing it, it quickly changes public perception.

The mask advice should have come in February, followed by bans on large gatherings (25+ people or some number), and then the lock downs could have come in a limited fashion in March as needed.

All those cute videos of cutting TShirts and socks and what nots to make masks could have been shown in Feb and people would have used them. Instead the authorities chose to tell such a stupid lie that it's almost insulting to our intelligence.
The title is 100% accurate, just misleading. "Data do not back" is intentional weasel language commonly used in university press releases.

Data does not back that if you (anorphirith) shoot me (wegs) in the head with an AK47, I'll die. That particular study has never been done). But we know it's true. But a carefully-phrased headline gets picked up by the popular press and builds university branding.

See also "significant" (which means "statistically significant," so might be a 0.000001% effect size with enough data, but which the public picks up to mean "big"). These are well-developed techniques for roping science-ignorant reporters.
And super nitpick but the font used connects s and t and it really looks out of place to me.
This is from 2019, and the title has not much to do with TFA except the hagfish slime part.

That said, hagfish slime does indeed look like quite interesting and unique stuff! Also cool that the hagfish seems to have evolved to actually lose its sight and other advanced functions, after its genetic ancestors worked so hard over to long to evolve them into existence the first place...
> So, they use a contract tracing system to identify and start investigating Bob’s direct and second-order “contacts”.

If "identify" means to discover the identity of, I don't see how law enforcement can do that under the Google/Apple system.

Law enforcement can get Bob's phone. And it will have a list of all the pseudonymous ids it collected. They can pull that data, but what do they do with it? The ids aren't IMEI or phone number or anything. And there is no central database of them.

If you had the contact's phone, then you could get data off both phones and confirm whether they had been nearby. But if you're confirming a link between Bob's phone and someone else's phone, it means you already discovered the identify of the contact through other means.

It would be possible to build a central database of these ids through dragnet surveillance, but since they are stored locally only, that would require putting malware onto the entire population's phone to upload the ids somewhere.
I got excited because my initial thought was of Galactic Battlegrounds, but then I re-read the headline. Battlefront was nice, but Galactic Battlegrounds was special.
There was this simple GPU hash table a while ago: https://news.ycombinator.com/item?id=22541925

It’s because the government is only buying mortgage backed securities right now for conventional residential loans that don’t include HELOCs which the bank would shoulder all the credit risk for.

If the government is guaranteeing one type of residential real estate loan and not the other it makes no sense for a bank to offer the one that isn’t guaranteed when they can just pursue practically risk free lending.
this was only during the test. In the actual direct mail piece, they had a price.
So disgusted with the misinformed obtuse responses that I feel I need to defend myself and break down every one

"The closest thing I can see is that the shorts are accused of closing their short position by acquiring shares in a secondary offering, which not only is legal, but also a smart thing to do if you think the offering is priced high and you're short."

Actually it's not legal. The reason why its not legal is because of what you said in the last sentence. You have to announce an offering beforehand so investors know what's coming. Pumping up the price with foreknowledge of an offering so you can short it to unsuspecting investors is obviously fraudulent.

"I don't blame you, the author miss uses the term short sellers in the beginning then uses it correctly later on. Which is confusing, initially they use the term to mean "any investor selling their shares of stock" which is annoying.
Then later they use it correctly WRT a firm needing to buy the shares they sold back to give them back to the original lender, which I assume in this case is Charles Schwab."

What are you talking about???????????????? There is literally zero truth to that statement at all, and it's the definition of obtuse

See this is the problem with micromanaging forums. All the naysayers are completely wrong, and now the post is flagged, even though hundreds of people read it and seemed to enjoy it.

Truly sick

Oh by the way, nobody knows about Gun and Run. It's a niche industry secret that I just shared with you for free...

Truly pathetic and sick that you would flag this
> This means is a magnitude faster than the previous one!

Is this right? It's a quadratic not an order of magnitude difference isn't it? And can you be an order of magnitude faster in an O notation expression anyway? Isn't an order of magnitude a coefficient? Don't we drop coefficients in O notation?
Cutting edge applied ML can do things that previously could only be done by humans. You're generating potentially unprecedented insights into your data because neural networks pick up on what I call "nonlinear" correlations - stuff that is missed with typical first order statistics like averages and skews and such.

So basically ML when done right is enormously valuable because it horizontally extends the reach of computation into previously humanlike domains.

But the caveat is that it's hard to do ML right. You need very much to be a generalist, an autodidact (to quickly learn the nature of the domain you're operating in) and I think a background in math and/or physics, or at least some other quantitative field is indispensable. You can do a hell of a lot more with neural networks than sort cat pictures or target ads.
> COVID-19 death counts shown here may differ from other published sources, as data currently are lagged by an average of 1–2 weeks.

> *Data during this period are incomplete because of the lag in time between when the death occurred and when the death certificate is completed, submitted to NCHS and processed for reporting purposes. This delay can range from 1 week to 8 weeks or more, depending on the jurisdiction, age, and cause of death.
the whole point of the app is to isolate people that have been in contact with positive cases before they become contagious.

"Can someone explain to me how placing a barrier in front of your mouth and nose can possibly be a BAD idea when the purpose is to reduce the entry of particles into the system?"

There are a number of reasonable arguments. Just a few:

* people who wear masks touch their face more often, which leads to greater infection (I personally observe this every day).

* masks give people a false sense of safety, and cause them to reduce social distancing.

* masks increase risk of infection unless donning and doffing procedures are followed correctly.

* telling people to wear masks causes them to seek out medical masks and N95 masks that are in short supply, and should be reserved for professionals (also personally observe this every day; people are walking their dogs in Manhattan wearing N95 masks, while hospitals literally beg for new masks).
While I agree with you, I think of it more like moving the complexity more than removing it. The simplest way to store junk is to throw it all in one space. This is categorically the simplest thing to do. However, your complexity is then moved to the point of retrieval.

If you want to reduce the complexity of retrieving items out of the garage, you can move some of that complexity to when you store things in the garage by organizing them in a certain way. Without a doubt this is more complex when storing, but we would all agree that it is a creates a good balance in complexity between tasks.

However, I would argue that if you ever only store 10 items in a garage, then spending time organizing them in a way that reduces retrieval time would be an utter waste of time, and hence (to completely jump out of my/our analogy) why a good business person takes all of this into consideration when making decisions on how to structure their code and business and what complexity to take on.
Rust is almost context free; there’s one relatively rarely used bit that requires context. And usually it’s only one or two bytes of it.
That's true. And the CDC did say not to wear a mask, and various other aspects of the US reaction are accurate. And the video doesn't even talk about faulty CDC test kits, banning of imported test kits, or other American own-goals in this crisis.

It does brush over some other details on the Chinese side, of course.
Is there a way to get ZFS on Debian the same way as with Ubuntu (for someone that prefers text-based installers and is fine with an unsupported solution)? Debian has always had more ideological purity that got in the way of users being able to actually use their machine efficaciously.
The Initiation and Spread of Pandemic Covid-19 in the United States
There is a note about a "hiatus" on the website though.
Yeah, I don't blame you. That is, unfortunately, how the system fails us; young people who don't know their rights or people of any age who are desperate to keep their jobs are really vulnerable to exploitation by shitty bosses who know that the balance of power is skewed in their favor. But that's a conversation for another thread, probably...
Congrats, it's now off the list of phone interview questions at Google.
It's as though no one commenting negatively actually read this article.

> We created this software on a request from healthcare staffs. It is not a commercial application. Even with this system, we strongly suggest doctors to visit their patients, take real measurements. As this software was developed fast due to prevailing pandemic situation, we released it with the most urgent feature monitoring. We tested this for long run, with multiple devices as well. So far it worked out well. It does not indicate this is perfect, we are working on improvements and fixing bugs until its very stable. Thus we have adviced doctors to use this with CAUTION

It's almost as if the options were either "Do nothing" or "Do something", and they chose to "Do something." This does not sound at all like someone just decided to build their own version of a software they already had access to. It sounds very much like they could either make this software or try to get along without it.
I eventually got to one that I could answer. The answer was awk as an alternative to sed. But I had to look through at least five until I found one that I even understood the question/riddle.
Since others were suggesting mawk too, I just installed it and it was indeed faster than GNU awk: The task took about 7 seconds.

Interesting enough: LANG=C increased the performance of GNU awk a bit, but actually decreased the mawk performance.

If anything the fact that I have a mask on constantly reminds me that I should not be touching my face. Every time I hand motions towards my face I remember that I have a mask on.
Having gone through this whole process myself last year, I would definitely recommend a static site generator. My site [1] is built on Jekyll [2], stored in a Github private repository and is hosted by Netlify [3] for free. The only running cost is the domain name.

Personally I didn't really enjoy setting up Jekyll since I'm not all that at home with Ruby so I would recommend looking at alternatives. Once it's set up though, it's very convenient to work with.

The Github repo is cloned locally, I write posts in markdown and then simply push to the repository. Netlify watches the repository for changes and automatically deploys whenever there's changes. It's very convenient. The compilation cost is paid upfront so the page is very fast as well. Last I checked, it scored 98-100 on all metrics in Lighthouse.

Ten percent less Democracy: a review
Thanks for the thoughtful response, but I don't agree with the reasons you stated. If we don't see a race to the bottom today, why would we see it in the future?

According to this [1], new car dealerships have a profit margin of 1-2% while auto manufacturers have a profit margin of ~10%. Anecdotally, some dealerships have no profit on vehicles, and rely on services contracts to drive profit.

I interpret this to mean that there is significantly more competition between dealerships than auto-manufacturers. If a consumer wants a specific brand, they can choose between dealers and often will travel long distances to get the best price. When a dealer buys a brand, there is a single supplier with global monopoly.

I think the disproportionate share of profit already going to manufacturers also undermines your argument on the trade-off between sales volume and splitting of profit.
There is absolutely no reason a teenager can’t nail these sorts of projects. And often being young has some big advantages in terms of not having got too comfortable with a salaried job and knowing what the next generation wants.

My advice (teenager or not) is join online communities like indie hackers and get all the help because anyone doing this at any age needs to learn diverse skills, it’s not just about having an idea and coding.

Nah. They're still issuing mortgages and refis. HELOCs are specifically for home improvement or other cash infusion. HELOCs have been going out of style for a while. Borrowers have considered them risky since the last recession, so the market has narrowed to less attractive customers.

I used to use this question before it became too common. Any reasonably-well-prepared candidate should be able come up with the O(N) solution and the follow-up is always good for a discussion: "what if the string is huge but the alphabet is small? Eg, a DNA sequence."

There's a single pass solution that's left as an exercise for the reader.
Replit sounds awesome, especially once you put it this way ("view-> source for code, plus a server"). Kudos to the team.
Interestingly, I've especially struggled with this with those in closest with. It can be hard to "turn off" your friendship and be more respectful with someone you are comfortable with. But when you're in a meeting with other folks, a joke that might come off as friendly (giving someone a hard time) is suddenly misinterpreted by others.
I think this is only about historic vulnerabilities from many years ago. I don't see anything about a new vulnerability.
I am citing the most common arguments made by experts in the field.

Unless you record yourself and count the number of times you touch your face while wearing a mask, your recollection is unlikely to be objective or accurate.
