They're actually marketing this freevalve tech for consumer cars. They already have a tech demonstration partner (a Chinese car maker).
One question that's been on my mind: The number of Coronavirus cases is likely far more than what's being reported. Apparently there are those who get coronavirus and are unaware that they have it before they heal. However everyone that dies of coronavirus is reported as a coronavirus case.

Does this mean that there's a good chance the death rate is lower than the current calculated 3% with so many recoveries going unreported?
Limiting ourselves to only ad-based news sources is not an upgrade.

Also, it's about time you learn how to bypass paywalls.
This is a pet peeve of mine since moving to the US. All the loud cars and motorbikes revving up at night, even setting off car alarms. Don’t remember that ever being a thing in Munich (which, you can imagine, has plenty of high performing cars and motorcycles).
I saw a report one day, where they interviewed many young people (<25) about their tech usage.

Most only used a smartphone and many of them only knew about well known apps like FB, IG, SC and WA, etc.

They were "natives" in their apps, but most of them didn't know much besides that.

Which is probably what you would expect and its probably still better than the mindless TV junkies from before.
> it was uncertain whether New Yorkers who aren’t used to cycling on the city’s inconsistent network of bike lanes —which are frequently clogged by parked or idling cars and trucks — would take the mayor’s advice

The notion that New Yorkers use bike lanes is funny. I live on a major Manhattan avenue with a bike lane and there is at least three times as much bicycle traffic on the sidewalk right next to it. Even motorized scooters are more commonly seen on sidewalks than the road. When I lived in Brooklyn I learned to peek my head around the corners of pedestrian bridges because motorists and cyclists will speed around them recklessly. The food delivery gig industry has put this behavior into high gear. It’s illegal, but New York laws are more like guidelines.

From my fire escape I can see a vacant lot that is used to store stolen bicycles while they are advertised on craigslist. I guess I wouldn’t have to go far if I decided to buy a bike.
Fake opinion about fake advice
The Wikipedia page focused specifically on antimicrobial effects of copper calls out that it has some effect on viruses. I don’t know enough to say if this is the same as the oligodynamic effect or just something similar.

They do claim it works on all stealth planes including the F-35, but the B-2 is now 30 years old and was designed in the mid 1980s. Detecting it from 150 miles is impressive, but when they're equipped with 250 mile standoff air-to-surface missiles, ultimately not very useful. I'd be curious how much better the stealth is in the world of supercomputers and CFD for modern planes as well.
Ideally we would all have our own stocks of essentials that we build up gradually over time during normal circumstances. Unfortunately this is both difficult for some people, and antithetical to the modern trend of urban minimalism.
I want to help. I had posted something here:

https://news.ycombinator.com/item?id=22577611

But will support any effort so long as we get it done. I can help from the medical and the technical side of things. What’s the best way to sync up?
Generally true, but we both know that it's not so simple, and I'm surprised HN took this bait so readily.

With JS, you have to worry way less about hardware-specific builds, platform-specific linking implications, differing system behavior and intrinsics, or any of the other substantial hangups that become relevant when you need to distribute a native application across a wide range of devices.

We don't need to repeat the rest of the thread where everyone hops in and says "tut tut, hypothetically, it would be possible for it to not be that way". We're talking about the way things actually are. In an ideal world, JS would've been out of the picture about 3 years after it was born. :)
Wow, look at those goalposts go! If you make enough exceptions to allow incremental change, then "immutable" gets watered down to total meaninglessness. That's not an interesting conversation. This conversation is about configuration management, which is still needed in a "weakly immutable" world.
NBA Team Says They'll Continue Playing the Season Through NBA 2K20 Instead
My original post:

>I have no doubt his intention really is to save lives, but a secondary motive is surely also PR. Perhaps the Chinese state had some role in this, as well. I'm not much of a conspiracy theorist, but I could see a possible benign conspiracy like them using Jack as a proxy to distribute these.

I said it was a secondary motive, and that it was a benign conspiracy theory. I only leaned this way due to the fact the outbreak originated in China and because Jack Ma may not have been able to do this without the approval of the government. That means it's fairly likely he either had to request approval, in which case the government may have approved for PR reasons, or it's possible they reached out to him and proposed or demanded it.

Even if it were the Chinese state doing it formally, I'd still say the primary motive is to save lives, even if there were also other motives. Like how the primary motive of the Belt and Road Initiative is to increase trade and uplift poor countries, but there are many other motives, as well. Again, this is the case for all large governments, not just China - the difference here is just the lack of separation between private and governmental action in China, which makes it difficult to tell to what extent this is Jack and to what extent this is the state. If it were somehow proven the state weren't involved in any way, then I would think it was more likely than not that Jack didn't have ulterior motives.

Either way, it's not something I care much about one or way the other. I wasn't the original person to say it was a power move - I just disagreed with the parent poster who suggested it being a global initiative made it less likely to be a power move. No matter his/their motives, it's very good he and/or the Chinese government are doing this.
The B2 is relatively ancient as far as stealth tech goes.

Also, most stealth aircraft are detectable on radar. The question is how big or small is the radar cross section. That’s not something this blog post digs into. Meaning, most of the time a B2 looks like a goose or a small animal.

Correction on my part: The B-2 and F-35 have radar cross sections roughly the size of a marble.
> but honestly the issue is still always communication. Why are people even touching files they shouldn't be touching?

Because there's 300+ people working on a project, and it's not feasible to know what every other person is working on or planning on working on.

The file lock (code can be merged too, just like git, so this is only really for binary assets) is a crude communication tool saying "hey I'm using this file".

> Meanwhile perforce is a pain for code heavy projects and requiring a central perforce server. Git works great there.

I think you're applying a git biased view here. I don't think perforce is unsuitable for code heavy projects at all (see workspace views as a prime example), and for the majority of people, having a central server isn't an issue. Most people treat github/gitlab as a centralised server anyway. I've _never_ in a decade of programming heard someone suggest adding an extra remote to git so I can share your changes, it's always been "push it as a separate branch and I'll merge it". If you have a missing internet connection, you're likely not able to share code _anyway_, and with p4 you can always reconcile offline work when you're back online.
Coronavirus: Scientists say UK virus strategy is 'risking lives'
If the law prevents the store from charging a high price to the consumer, then that effectively prevents the factory from charging a high price to the store, because the store would make a loss if it accepted that price.
yes, there was those exact words were said. at 15:30, peter levine (a16z GP) says 'recent studies show you guys are the second largest cloud provider by number of server instances, second only to Amazon'

I'm still pretty new to cloud - do you mind explaining why number of instances is not significant? sounds pretty significant, it indicates active, paying usage i think?

> So your answer aren't really technical, but more on the economical and business side of things.

i can accept this. but are all "new cloud startups" doomed this way? (I work at Netlify so I have a vested interest in this haha). At some point there's some sort of Glass Ceiling where you run out of everyone willing to Not Buy IBM.. and then the Big 3 clouds just clone you and run away with it? seems pretty bleak for the risk/reward of innovation/VC money.
I find it odd we don't hear anything about the mild cases. If I didn't know any better I would assume if I got coronavirus I would be on my death bed.
Afternoon in the Pandemic
The bus is pretty usable in LA. Most major roads have a bus line going up and down them every 10 minutes. High capacity routes are given articulating busses.

Despite the proportions of ridership being low, functionally it is pretty high, and the entire transit network does hit capacity during rush hours.
> yes really, most engines don't even last one season

"Even" one season? If they last more than one race it means they didn't push it hard enough so it makes sense that the engine last just marginally more than the race.
I think it’s better than the hubristic and idiotic mentality of hackers thinking they can hack the medical field. This ventilator design sucks. It was designed without input from a pulmonologist friend. People are talking about it like it’s a reasonable response to the problem. This madness is worse here than anything.
I suspect the author overheard gallows humor as a coping mechanism in a conversation he wasn’t a part of so he had no context. Or maybe he overheard a couple of jerks. Some percent of jerks exist in every generation. That said much of the lack of empathy in this comment section depresses me more than the two guys walking down the Upper West Side. I sincerely hope this young generation radically changes the world. All of you castigating an entire generation facing down an imminent threat to their lives - well you may find as you age that it’s not as easy as life goes on to break out of a system from within as it may appear.
There is no evidence in the article to assert a B-2 was actually detected at 150 miles outside of unverified claims.
Now if only it would index the actual web pages of the browser history.
I think the sample handling part is faster than the PCR part, but you might have more than 1 PCR part setup on the machine.

So if that is true, it isn't labs multiplied by the PCR rate to get to a testing rate, it's the sum of the bottlenecks of the installations.
Such a weird dichotomic view can only come from someone who’s never lived in Europe. Loud cars and motorbikes weren’t a thing in Germany, where I lived for 30 years, and yet I had the impression that my privacy was also much better protected and respected than here in the US.
Only semi-snarky answer: The song and dance of drivers, and not having to reboot.

Plenty of mainstream PC configs are going to be a hassle to get to functional parity on the Linux side. You can complain "it's deliberately crippled hardware/bad drivers" but odds are, the guy buying the fleet PCs are not checking if they're Linux-friendly.

If I just want to run some command-line dev tools, I can probably get there faster by installing WSL than trying to start with a Ubuntu ISO and setting up the nVidia drivers.
Cats and Dogs Can't Get Infected with Coronavirus, Says WHO
https://en.wikipedia.org/wiki/Passive_radar

In a passive radar system, there is no dedicated transmitter. Instead, the receiver uses third-party transmitters in the environment, and measures the time difference of arrival between the signal arriving directly from the transmitter and the signal arriving via reflection from the object.

Passive radar systems have been developed that exploit the following sources of illumination:

Analog television signals
FM radio signals
Cellular phone base stations
Digital audio broadcasting
Digital video broadcasting
Terrestrial High-definition television transmitters in North America
GPS satellites (GPS reflectometry).
I look at it a different way, from a first world perspective, the power still occasionally goes out. As a comfortably middle class American, you wouldn't say "I have a $200K house and it's the latest tech and therefore it must run only on electricity". For the sake of argument, let's say you don't use natural gas or heating oil. You still are not going to say "oh, I won't buy a Honda generator because it's more important to maintain my electrical purity than to not freeze after a storm".

Not everybody needs or buys a generator, but there's no trend to eliminate them, and in the big picture, using them is the exception, so it's not what we should be focusing on to cut CO2 emission.

So, my opinion is that most people who have a comfortable first world lifestyle in the long run will end up with PHEVs. Not as a transition to all-electric, because it's just as dumb to have a battery that goes 400 miles to avoid range anxiety as it is to have an ICE that makes 400 hp to avoid "acceleration anxiety". All people need is a very small ICE, a very small battery, and a fairly large electric motor.

All the arguments about why pure electric vehicles are the future are based on emotional feelings about purity, not logic, I think.
And I would like to know how many people have died not due to coronavirus but it was labeled so because they just happened to have it when they passed away.
Isn't also true for influenza? I had flu symptoms back in January but other than telling my manager that I was going to be out of the office due to illness, never reported my flu to anyone. Doubt I'm the only one who did this.
1. Most of these sites have workarounds (eg posted above)

2. If you don't want to pay for a subscription, that's fine but it's a little silly to demand others don't share content from a news site they subscribe to especially if it is reasonably popular
Keep in mind that when you open YouTube from a blank history, you're not seeing what most people see when they're on youtube. In fact, due to their personalization algorithm, I doubt that there really is such a thing as a typical YouTube user.

A quick web search suggests that there are 2 billion MAU on the platform, with 73% of US adults using it (roughly 180 million people) [0]. Opening YouTube from a private tab in the Midwestern US, I see a range of recommended videos published over the past five years, with about 1-100 million views each, most of them between 20 and fifty million views. This content is all largely inoffensive, clickbaity, and in-line with what you might expect from a publication like Buzzfeed, or viral content in the 'tens.

These videos aren't the fastest growing, in fact it given their view:age ratio they've mostly peaked, so they were likely selected to appeal to the broadest swathe of the population possible, in order to kickstart user engagement.

Even assuming this content is only seen by Americans, the most popular videos presented have only been seen by fewer than half the platform's users.

Interspersed among the cute animal videos, the movie ads, the top n lists, and late-night TV compilations, there seems to be a selection of niche content which could be used to begin sorting you onto different user buckets. Sports videos, gaming channels, indie animated shorts, youtube poops, some Spanish content, etc.

The trending tab seems even less representative of the userbase. Its engagement is in the hundreds of thousands, to maybe a couple million over the course of a few days, with notable exceptions being a few music videos, and a recent episode of JRE.

I work with a lot of technically and "high culturally" illiterate people. A few that would be truly considered lowest common denominator.

Not too many of them are clamoring to see the latest music video, or gushing over that Minions movie ad that YouTube thinks a new user might want to see. Nobody really gets on YouTube just to watch top ten cute animal videos unless they're really high.

Videogame videos? Certainly, but there's a huge variety in those. A lot of using YouTube to learn new skills, or view product reviews. Not everybody's after the same kind of high brow content in niche x. In fact, they're likely after relevant, intelligent content that you don't even consider exists assuming they're older than 17. There's just too much variety in the population for that.

But sooner or later everybody watches a movie trailer, or a music video, or a fall compilation, or a top ten list that fits their fancy. Their typical view? Not likely. But it's something everyone will probably watch. So that's what YouTube's going to show an unknown user.

If you're disheartened by what you see, don't be. Just because everybody watches schlock doesn't mean nobody's watching in-depth, intelligent content. I'd wager most are.

Scientifically, yes. Politically, suicide.

Herd immunity is what you hope for once the infection has gone through the population. To the extent that they try to build it by telling people they must be infected with it (questionable, and arguably a misinterpretation of public statements) it will be perceived as an attempt to cull the lower classes for the benefit of the ruling ones.
Be mindful about setting toxic company cultural expectations from your generosity. Others within the org may not want to give their time away for free.

I'm a person who has been easing into CMake use over the past few years.

Something I've noticed is that there is no such thing as a single good introduction:

* CMake itself is changing. While the "revolution" of modern CMake is upon us already from version 3.0 (or a little earlier), a bunch of thing change with versions 3.12, 3.13 etc. See: https://youtu.be/y7ndUhdQuU8

* Different treatments - a mini-website, PDF presentation or conference video - focus on different aspects of work with CMake, but you probably need most or all of them in focus in order to actually do what you need done. That's how you can see videos entitled "More Modern CMake" and "Oh No! More Modern CMake"...

* Setting up the CMake machinery to have your repository/project installed is the opposite of straightforward, and very easy to get confused about.

* There are a half-dozen different ways to have your project depend on on other code: External projects, package management CMake modules, relying on other projects being installed in a CMake-idiomatic way and then find_package working, and more. Regardless of which you think is the right one, you'll need to live with others doing something else.

So, do follow the link, but don't expect it be sufficient.
Well, I'd much rather buy a particular brand vs store brand than paying some dick $50 on ebay or amazon.
The EOF condition for stdio functions is supposed to be sticky, although glibc didn't implement it correctly until 2.28:

https://sourceware.org/bugzilla/show_bug.cgi?id=1190

https://sourceware.org/legacy-ml/libc-alpha/2018-08/msg00003...

> All stdio functions now treat end-of-file as a sticky condition. If you
read from a file until EOF, and then the file is enlarged by another
process, you must call clearerr or another function with the same effect
(e.g. fseek, rewind) before you can read the additional data. This
corrects a longstanding C99 conformance bug. It is most likely to affect
programs that use stdio to read interactive input from a terminal.
The dividing line for what's on topic on HN not fact vs. opinion, it's intellectual curiosity (https://news.ycombinator.com/newsguidelines.html). That doesn't limit itself to authoritative information, by definition.

Speculation is inevitable. The question is whether it's curious (thoughtful and fresh) or uncurious (reflexive and predictable).
Those missiles will help you how though? They are mostly radar seeking for target information.. this doesent emit though. This only collects. So you need reconissence by drones ( easily detected with this) ..

Sorry, but this literaly breaks a billion dollar technology. Due to the distributed nature of the natural sources, it doesent matter what angle you reflect - a stealthed object will always be a distortion to the background, which alot of computation can the filter out.
The new rules set the limit at 3 engines per season, which is 21 races plus testing. So it's a balancing act, but you definitely need to reuse the engine for more than 1 race.
Koenigsegg Gemera use their direct drive system, with only one gear. So the engine will only see max revs when you're traveling at top speed, which will probably be quite rare since it's 400 km/h (249 mph).
Which avenue is that? Whenever I am cycling I see most people in the bike lane if there is one available.
> However everyone that dies of coronavirus is reported as a coronavirus case.

That seems unlikely.

Testing capacity in lots of the world is extremely limited. The US is reserving test kits for the most sick/at risk; people at a low risk are unlikely to be tested.

It seems to me that the focus would be on testing alive people, and that we are subsequently undercounting deaths - at least, in these relatively early stages.
> I think the self defense argument is very much biased by the fact that once others have guns, you may feel threatened not carrying yourself; conversely if no one carries you'd rather it stayed that way...

Guns are not a prerequisite for feeling threatened. The self-defense argument is based on the fact that two arbitrary people armed with guns are much more likely to be evenly matched than two disarmed individuals. In particular, habitually violent individuals tend to be much more experienced at, and prepared for, unarmed combat than the general public. Skill with firearms also benefits from practice, of course, but almost any armed individual would at least stand a chance of winning against a determined attacker, whereas someone without extensive martial arts experience would be unlikely to successfully defend themselves in hand-to-hand combat. Guns represent an equalizing force.
