for those interested, this find was made possible by what I as a (recovering) geologist believe to be the coolest event on Earth---a kimberlite pipe. Created in the deep mantle, these extremely dense magmas melt upward at increasing speed, breaking the surface at more than 100 mph. Would be cool to see--and of course there's the diamonds.
If you think about it, it's a shortcut for drawing blood and analyzing it to see what antibodies are in there.

As long as the marker has zero PII, just what vaccine was given, this seems harmless enough and vastly more helpful than the current paper system.

The potential for abuse is limited because you need to have the person in front of you, and then the only info is a vector of vaccine administered bits.
our online editors + a ci/cd pipeline to build Kogito services would be great. The `kogito` cli can be used to get that kind of workflow -- you can point it to a git repo with, say, a BPMN or DMN file and get a working service out of that ( well bugs aside :^) -- it's all very in flux ) take a peek here https://github.com/kiegroup/kogito-cloud-operator#deploying-...

> private entities are giving out sanitizers, increasing hygiene and cleaning policies, putting up posters for awareness, coming up with contact-less procedures for public interaction, hiring people to fix online shopping demand

You're helping to prove my point. These are all reactive actions that simply attempt to mitigate the problem. I've personally upped my hygiene, policies, and mask / hand sanitizer use as well. This isn't going to actually solve the epidemic, but it will reduce my own exposure now that it's a major problem.

Where was the private company temperature-checking international travelers in February, testing, and quarantining or contact tracing as necessary?

Proactive prevention requires focus and coordination. A team that is paid to sit around looking for specific threats will take them seriously, while businesses (really all entities, including individuals and the non-specialized parts of government) only respond to the current conditions. Large companies could certainly employ similar risk teams, but don't seem to have done so for the current problem.

> deal with the fact that they were inadequately prepared for this crisis

The entire medical system, public and "private", is unprepared for the crisis. One could make the argument that if healthcare had been a freer market there would be much increased hospital capacity, but I don't see how this makes sense given businesses tendency to be reactive. Supplies like masks could have been easily stockpiled by companies and sold at a decent profit when needed, but weren't.

> They've also started with curfews, sent military police to private premises to "count" heads in case they go above some magical government number, prohibited public-dissemination of information by epidemiologists without government-approval.

You'll get no argument from me about these being injustices. But I think the real anti-freedom jackboots are going to come out when people start dying in significant numbers from hospital crowding. Which is kind of my entire larger point - when situations are allowed to get out of hand, restoring forces step in and none of them are conducive to lofty ideals of freedom.
Not one comment in here is positive which saddens me. In the end, HN should encourage people to build awesome solutions. But even Dropbox got negative comments when they launched on HN, so maybe this is just how things work.

So here's my (positive) take: Great work, thanks for sharing. I especially like the design of the page, playful but still clean. AFAIK there's a similar app from toggl themselves, what are the advantages of your solution?

> If I have to adjust my monitor brightness to be okay with reading something there's a major issue.

Yes, but the issue is with your monitor brightness or your ambient lighting, not the content. I tune my monitor for use at night with the lights on and as a result, #000 on #FFF is perfectly comfortable at all times. There's rarely a good reason to use a PC in complete darkness and I can't think of any reasons to do it in your own home.
> I'm so not used to having breakfast that any time I try to I get an awful nausea.

This is likely just force of habit. Force yourself to eat something light - just a yoghurt or a piece of fruit - in the morning for a few days, and the nausea will likely go away.
This is a total fallacy - those troops being stationed in Germany does not mean Germany would station 30k of their own should the US troops leave.

Thanks for the story by the way. I thought it was great.
The sample has serious flaws and is quite unrepresentative of the population:

>We examined a group of 16 healthy young men (age 23.6 ± 2.3 years) with a normal body mass index (22.5 ± 1.1 kg/m2)

Size, demographic, gender, and BMI are all seemingly within the same cohort. I have seen neurological studies with an n=8 be the predicates of clinical practice because that's what the patient population on the East coast is, but this could have been expanded.

When looking at the results section, it looks like the data lines up almost inversely. Where if you have a high calorie meal in the morning you'll burn more calories throughout the day whereas eating at night you'll burn more calories at night. But they didn't measure calorie consumption from 23:00 to 7:00 so we have no idea what the measured consumption is.

Maybe I'm naive, but every time I talk to one of my colleagues with a PhD in nutrition they constantly say the same recommendations: eat a diverse diet free of sugar, try to avoid salt and red meat, and get your fiber. Meal timing has been shown to be more for the mind that for your health, in that it doesn't matter when you eat, how much you eat, but you eat correctly. I'll get off my soap box now.
The "oral history" part makes me think the "ledger" exists in the collective memory of a community. Plus, the value is purely defined on how hard the artifact was to get, not on any kind of intrinsic utility.
It’s controversial. Some would characterize viruses as alive (because they replicate and evolve). So it’s fair to say that you can kill them (prevent from replicating). Debating the semantics of this is not helpful.

I haven't seen any evidence supporting the argument that they do not protect the wearer. The argument seems to be that they aren't 100% effective at that, and therefore shouldn't be used for those purposes, which doesn't make any sense. Even 20% reduction in the amount of incoming droplets is significant - both for protecting the wearer, and for reducing R0.
There was a conversation recently on HN that I can’t find just now, where an expert claimed a DIY ventilator project will most likely only create a ‘glorified CPAP machine’ and that real hospital ventilators are much more complicated and require specially trained people to use properly, as they can be very dangerous.

Not to dissuade anyone from trying to make open source ones a reality in the long run though...

> The other big challenge I never resolved was how you'd account for e.g. using 1/4 cup of flour out of a bigger volume. Or taken to its extreme, cooking oil. How do you know how much your 'splash' is? You can't predict the remaining volume without a lot of fiddling to measure it and that defeats the purpose.

Definitely. Or, even, just taking some snacks to another room, and later placing it back to an 'intelligent' cupboard, let's say. In extreme cases, one may need be under a constant tracking at home.

But, simplifying, another option may be to use an improved voice assistant when cooking. One would need then to interact with the VA to note and confirm the stuff used. Improved VA, in essence, would try to 'understand' the activities and interact, instead of being a passive one (as most of currently are), that one needs to say commands. This would require adding it access to camera and maybe other sensors available at 'smart' home. Definitely a lot of interesting and challenging problems to tackle not forgetting too about the user privacy part.

}

Do you know if there are clients for Instacart (and/or other food delivery services) available?

Cups are an absolute nightmare of a measurement system.

In the UK, Imperial (284ml - i.e. 1/2pint), metric (250ml), and 'US customary' (237ml - i.e. 1/2 US pint) are all commonly sold. Less common is them actually telling you which they are.

In fact they mostly only say if they're US (though not stating that isn't a guarantee they're not!) because that's a selling point - people almost exclusively want them for following American recipes, they're rarely used here otherwise.

But for some reason that doesn't stop the others being sold.

Recipes also rarely state which. Or they'll say '250ml' but you suspect they're probably actually just rounding from US cups.

It annoys me out of pedantry and ambiguity, but with my other hat on, I think people care far too much about precision in recipes and following recipes, to the detriment of their cooking. For the sorts of things you're going to use a 'cup' for, being 20% off (Imperial vs. US) is probably fine; obviously more so the more ingredients there are in the recipe that are measured with cups.

> I was replying to the idea that virus has been circulating “for months” undetected.

I don’t think that’s crazy at all. We had our first case sometime in January, and only until very very recently have we had any significant travel restrictions. It’s very contagious and for a significant number of people there are no real symptoms, or if there are, nothing life threatening. I don’t think it’s crazy at all that it’s been working it’s way around the US population for months.

Maybe to put it another way, if we could instantly test al 300+M Americans right this instant, would you be surprised if say 20M or so tested positive or had had it?
they only have 10 tests. 10 tests, 10 cases. not great, not terrible.
I was gonna say positive things until the page-wide unclosable buy-me-now popup jumped up. This is the kind of web no one wants to touch, even with a long stick, never mind sponsoring it through an annual payment.
Or maybe shouldn't there be emergency plans that had all the steps to remodel current production lines in the country to adjust to production of medical supplies?

Like, in China, factories that made bedding products are re engineered to make masks, suits, etc.

These are exceptional conditions, so if you had the protocols in place (blue prints, machine configurations, assembly line structure, briefings for management, briefing and courses for factory workers), maybe it was doable.

And maybe it would be of low maintenance, just when new machines were introduced, you'd release a new document to configure that machine.

The main problem would be raw material, but again, maybe with planning and study new materials and combinations could be used (even if not perfect).

This would be only a problem for countries with little to no industry, but that's where organizations like the EU should come into play.

Ask HN: Would Asthma Inhalers have an impact on Covid-19?
Since COVID-19 goes after the lungs and things go downhill from there. I wonder if asthma inhalers that have steroids would have any impact since it goes directly to the lungs.

Of course this would have to be early on before the virus starts turning your immune system against you.

It's not really about wealth, though. No one is asking or cares what the Walton heirs would have to say.

It's the fact that Bill is smarter than the people in charge of our institutions. And he has a lot of experience in this domain. And has been warning about exactly this problem for many years. Indeed he warned that pandemics were our biggest blindspot and threat.

not really. most forms of insurance are not mandated by law and try to charge people something like the expected value of their claims over a certain period plus a profit margin. if health insurance were allowed to operate more like other kinds of insurance, healthy young people would pay a couple hundred bucks a year and old people would pay tens, if not hundreds of thousands of dollars. an eighty year old buying health insurance is the equivalent of someone with five DUIs, multiple at-fault accidents, and a ferrari trying to purchase car insurance.
To add to your comment, they measure calorie expenditure throughout the day but seemingly stop collecting data throughout the night (23:00 to 7:00). Their conclusion that breakfast is better isn't because they compared the data from the day to night, but because they didn't have any data throughout the night.

Maybe I'm stretching this, but I want more calorie expenditure while I'm sleeping and having the highest amount of somatotropin in my body so it can mobilize proteins and facilitate healing.

Your compliance point is salient. I can recommend every single therapy in the book, but getting a patient to take a drug let alone at the correct time and correct dosage to maintain therapeutic index, is an art.

I didn't say that. I said that, without the US presence in Germany and without NATO, Germany would have to spend more on defense.

I don't understand how anyone can disagree with that; it's obvious. The German government certainly knows it, which is they allow the Americans to keep 30,000 troops in their country.

A lot of people on HN have an extreme anti-US bias. It's pretty tiring.
Why are nutrition and social studies considered science?

They chart out a few numbers for very few people; have no understanding or analysis of the underling biological or biochemical processes. The later of which is hard, grungy and boring science - but that's really the important high order bit.

This is hack territory. It's the easiest science with very low bar, but at some point we have stop this madness.
Humans are wonderfully crazy at times. This really tickled me.

Excerpt (one of the details that delighted me):

The extrinsic (perceived) value of a specific stone is based on not only its size and craftsmanship, but also its history. If many people—or no one at all—died when the specific stone was transported, or a famous sailor brought it in, the value of the rai stone increases by reason of its anecdotal heft.

Audi Carplay has this too, their screens don't even allow touch.

I put a Sony XAV-1000 in my '07 Honda Fit recently, it was the only Carplay unit I could find with a physical volume knob. You can hold the volume knob down to activate Siri, so I never have to actually use the touchscreen. It's been very nice for Apple Maps/Spotify, I'd recommend looking into it.

Didn't we cover this in SARS-COV-1 and Ebola outbreak 1 and Ebola outbreak 2 and Ebola outbreak 3? It takes a while. Generally months. When one of these shows up, you'll hear some news about an expiremental vaccine and someone volunteering to get it, but it normally takes quite a while- -months- to get all the stuff in place to actually get it to your kids.

Betting on a vaccine swooping in to save isn't smart.
A flaw in this technique is that you only get particles from things on screen. If you want particles to fall from off screen down or float up into view, you have to compensate with a traditional CPU particle emitter.

Pretty funny post. I'm sure we've been told such high tales too and actually believe them.

Our legal system does usually involve "proving damages".

Obtaining autonomous vehicle IP is not equivalent to having autonomous vehicle product in the market.

As an example: Boeing could almost certainly publish all of the IP for the 787 jet and not risk spawning a single legitimate competitor. Very few organizations in the world could do anything with it.

What's truly valuable to a Google or Boeing is their financial, engineering, manufacturing, and operations resources. And other less tangible things.

Which is why severe punishment for illegally copying IP doesn't make a lot of sense. Yes, it should be illegal and should be stopped, but it's not that big a deal in most cases.

It just seems like a big deal because "tHey StolE tHe SeCreT cOdEs!" as if it's a James Bond movie.

It's a case of confusing the golden goose with the golden eggs.
Yes I recommend toasting of yeast breads if your new to baking bread, mainly to reduce the chance of exasperating a Candia infection from consuming live yeast.

If you bake bread properly all the yeast will die, but it is pretty easy to underbake it, especially if your new at it.

I found the main reasons I underbaked in the beginning were opening the oven to check it, stopping early because it looks dark and the most common way was not letting it cool before cutting into it. (Bread keeps cooking on the inside after you take it out and when you slice it too early it looses it's internal temperature too fast)

Toasting it will kill of most live yeast. Another really good tip I don't see in recipes is while your bread is still warm but not hot enough to melt a plastic bag, wrap it up in the bag and the remaining moisture in the bread will soften the crust.

Nothing worse than a sharp, rock hard crust around a slice of soft bread.. IMHO.

Good luck!!

> Does anyone excercise any critical thinking skills with these headlines.

Critical thinking means carefully examining evidence, even if it challenges "common sense".
It's brilliant really. How else would you select for people straight out of school (age), with the time (few commitments and probably no dependents) and willingness (willing to jump through arbitrary hoops before you're even their boss) to grind all variations of the interview problems, all while maintaining plausible deniability to discriminating in these ways?

As someone who graduated recently and is going through this process right now - I always thought I would be set because I'm a decent problem solver, aced all my algorithms and data structures classes and generally could solve most interview style problems I came across. I've learned that this is not enough. An organic problem solving process might involve trying several promising approaches, or starting with a suboptimal algorithm and realising improvements to it, and then you might figure out an optimal solution. In many of these interviews the time constraints can be absurd, you basically have to have done the questions or variants of them recently to be able to write down the optimal solution in your first iteration.

Today my friend had a first round online screening from Atlassian - 5 questions in 90 minutes, and none of them were trivial warm up level questions. Compound this with the fact that it's often harder to solve problems and think creatively when you're under time pressure in an interview, and you realise that your only option is to do 200+ Leetcode problems and just hope your interview overlaps with those problems.
