Unless someone who has it is inside your home I don't think you need to worry about the air recirculating. I agree though its amazing that people don't understand how this works.

Here is a video about this robot. https://www.youtube.com/watch?v=qFmeHPVtK0o&feature=emb_rel_...

But do 300*10^9 emails really get sent through gmail every day or is that in general?

>> More than 300bn emails are said to be sent every day and if only one-third originate on Gmail—a conservative estimate—then a stack of print-outs would be 10,000km high.

Given: thickness of paper 0.0039 inches Lets say each email is at least a page

0.0039 inches * 300*10^9 pages to km = 29,718 (km)

Maybe if some emails are more than a page its not too far off.

> I have a friend that refuses to wear sunscreen because he feels like the risk to his health from rubbing all the "unknown chemicals" into his skin outweigh the health risk of skin cancer.

I do wear sunscreen at the beach or if I am going to be outside in direct sunlight all day. I do question however if the risks posed by what is in sunscreen outweigh the protective benefit if you put it all over your body every day. I am not a doctor or expert in this so don't listen to me.

You might say the data drizzled out...

I always think of Brazil as hot and humid but I have never been there. How cold does it get in southern Brazil? I also never realized how large some countries are as far as population.

I don't think flu strains are a type of coronavirus but I think some of the common cold strains are.

This is what worries me. Although I would imagine that if that was the case we might be seeing it in the southern hemisphere already.

I don't trust the WHO but I have certainly not written off COVID. I think the WHO has too much China influence but I think they may still have some accurate information.

I don't know if its seasonal or not yet although I could see experts could start making predictions already. To me though it is not one big wave. Watching the numbers in the USA and other countries it appears that as restrictions are lifted cases rise. When they rise we add restrictions and they go down at a much slower rate. Its many smaller waves.

Yeah, your right https://news.ycombinator.com/item?id=23935317 .

I shared this because I thought it was interesting and wanted to see what the HN community thought. I should have searched it first.

Which appointee?

I am not the person you are replying to but I would imagine they mean "job security" as in if you get fired you can find another pretty quickly.

I am not sure who said it originally but I heard a quote that resinates with me and this idea. "Honest conflict is better then dishonest harmony."

I like the idea of discussing topics that are controversial. Its actually annoying when someone tosses out a viewpoint that I disagree with but they are unwilling to discuss further. I have actually shifted my views over time by talking it out with people I disagree with. In some cases it strengthened my conviction or made me more prepared to defend my viewpoint but in some cases I do change my mind.

The issue is that online it does usually devolve into a flame war where nothing productive happens. Or the thread is flagged. I am interested to see if this is really going to be different. I installed it just to see how this works.

I think for some products on shopping.google.com you can already search within your area. I think it it does not work with all products though I know I have seen it on some. Like electronics at Best Buy.

Just search on shopping.google.com and then in the filters on the left side check the box for "Available nearby".

Why was this flagged? Many stories which I am interested in get flagged and I do not understand why.

From what I am hearing the antibodies that you get from having the actual virus do not provide protection from re-infection for very long. I cant find the source but I think it was a Medcram lecture. Would antibodies be from a vaccine be more effective at preventing infection then getting the actual infection? I thought usually it was the other way around.

I wonder how they know how the shooter was dressed if the son died and the husband is in critical condition. Ring doorbell camera or maybe the son or husband was able to give a description before passing or going to the hospital. I hope there is video evidence.

If this was a hit/ attempted hit by a party that is worried what the Epstein case would uncover something more incriminating then I would think would serve to intimidate any future judge put on the case.

To be clear though I think judges, prosecutors and law enforcement face threats on a regular basis and many of them have the guts to do the right thing. Granted with Epstein case this is a bit more scary then the usual cases. Its connected to such powerful people.

I actually believe this to be the case. From what I have read researchers often do something called gain of function research. In this research they add genetic features to viruses that could make it more infective. This is done, at least in part, to help learn how to protect society from such a virus if it were to evolve naturally. I thought I heard somewhere that one of the functions coronavirus has that its closest known relatives do not have just happens to be something that virologists frequently add.

All this leads me to believe it was created in a lab. Likely for altruistic purposes but still. When this escaped whoever knew that it was from a lab should have disclosed it ASAP to help the world prepare.

I have no experience in virology so don't trust me.

Yeah, I really don't understand this. There are also people on nextdoor claiming that they spotted "the Colorado drones" in my neighborhood which is nowhere near north west Colorado. At this point I think people are just seeing anything in they sky and assume its "the drones" spying on them. The news also says that they are not violating any laws currently and that we need more regulation of drones. And then local law enforcement says they do not know who it is but its not them. I really doubt this because it is not legal currently to fly a UAV at night without special permission. Also the area it is reported to be happening is near a bunch of ICBM missile silos. I suspect it some military thing and when it made the news they just let people think whatever they want in part because it will get people to be in favor of more regulation.

I fly small tinywhoop quadcopters around my house. Its a 21gram palm sized quad with fpv camera. Some people have a hysteria about drones and assume that you must be spying on them. If they could see what I see in my camera they would realize you cant see much detail of a person unless you get pretty close.

The original poster that you responded to and that I was saying was correct never said "most Chinese citizens are being systematically disappeared, tortured, and killed". I think you moved the goal post.

Exactly its not as if we do not have issue in the USA and we did have a dark history (slavery for example). I think many Americans do not know how good we have it. In some ways our worst enemy is ourselves.

> most Chinese citizens are not systematically disappeared, tortured, and/or killed

So some being systematically disappeared, tortured, and or killed is okay?

Here are a few recent examples of human rights abuses in China.

In China there is no freedom of speech. Foreign companies can have their IP taken from them.

In China you can go to prison for years for simply saying what I am saying right now. https://www.bbc.com/news/world-asia-china-52765838#:~:text=U....

This guy made it economical. https://en.wikipedia.org/wiki/Percy_Gilchrist

I have been to China and have family from there. I can confirm that what he is saying is correct. China plays by a different set of rules.

Knife laws vary allot by city and state.

In Colorado I believe the maximum length allowed is 3.5 inches in blade length. This sounds simple but can even be a grey area because some knives like Spyderco have a part of the blade thats not sharpened and technically part of the handle.

NYC used to be very knife unfriendly and you could get charged with carrying a gravity knife if the knife could be flicked open in any way. Good news though as it sounds like that changed https://reason.com/2019/03/28/federal-judge-rules-new-yorks-... There was still a case in NYC of a chef who was charged with something for carrying a very small pocket knife on his way home from work. He was charged with something for the pocket knife but from what I remember it was totally okay that he was carrying a bunch of large chefs knives in his backpack.

Its important to read and understand the law as well as how its actually enforced.

I live in the city and carry a knife where allowed. I use it to open boxes and packaging, cut food, turn screws (sometimes when they fit), pry things open, pick out splinters, strip wires... Its the most basic tool.

The other day I was replacing my windshield wiper blades and needed to pry out a small adapter that they came with and used an old knife I keep in my car. I was doing this in the parking lot of the auto parts store because the first set I took home did not fit correctly even though the computer said they did.

I would not call him a metallurgist but this guy has tested a bunch of steels using an unscientific rope cut test and documented them in a spreadsheet. He was the first one that convinced me to spend over $100 for a cpm-s30v knife and it was way better then anything I had before in edge retention.

His data cant be that bad though because I built a model to predict the number of cuts for a blade using edge angle and metal compounds (no real way to take into account heat treat though). It was relatively accurate for the less exotic steels. I should really share that with the world.

He also records videos of himself and posts them to his youtube channel along with other knife reviews.

At one company where I was the interviewer the company used a few simple java questions for each screening (not great I know). It was basically just a way to make sure they did have experience with Java at at least a junior level. This became an issue when we started getting candidates from recruiters. One candidate bombed on the first question. Then when we asked the second question they answered the 3rd. Clearly the recruiter was trying to coach the candidates based on past questions.
