This is why the money has to go to the bottom so it can bubble up. All debts get paid off along the way. Government bails out the small business, the small business pays the distributor, they pay their creditor, etc. Investors still make money at the top.

If bubble up economics becomes a thing I want full credit.
When everybody can do the thing, the thing becomes less valuable...Case in point: We watch RV content on Youtube. There's a half dozen publishers with truly compelling content, and 100 more with polished video, trying to self-support their RV hobby through Youtube.

Likewise, the amount of music on Youtube is boundless, because everyone with a Mac has a sound studio, for free. makeing the amount of revenue each person is potentially worth...less.

This isn't good or bad, it just is. There's 10,000 people making Hundreds instead of 10 or 100 people making millions.

This is 100% anecdotal but I saw it snow the other day in Tokyo in March and it’s been very cold. It’s been a while since it’s snowed in March I’m sure.

I’ve also noticed the Japanese alps we’re having a super bad winter until a few weeks back when things kicked into gear and the snow started falling again.

I have absolutely no idea but Is it possible to have a short term decrease in emissions change the weather like this ?
This is a bit misleading; you're losing accessibility only if you're never rendering to the actual DOM. A virtual DOM is just a way to avoid interacting with the real DOM until the last second, it doesn't really have anything to do with your final render target.

Svette avoids a virtual DOM while still rendering to the real DOM. It keeps itself fast by compiling your code to optimize unnecessary operations beforehand. Svette can still be used for accessible web apps.

JQuery and pure Javascript just manipulate the real DOM. This can come with performance consequences, but for many apps, the performance consequences don't matter. JQuery/Javascript can still be accessible.

React/Preact/etc... all use a virtual DOM. They can be accessible as well.

The virtual DOM is not the thing that gives you accessibility. You could have a virtual DOM that rendered to canvas and it would not meet accessibility standards. Accessibility is determined by your final render target, not by how you get there.

Short Guide: How to Go Remote Overnight?
That is a deeply stupid trope and conspiracy. War for profit, the glorification of war, and even propaganda have long predated the very existence of Judaism.

The whole concept is a feudal peasant propaganda going onwards like a zombie or a stray bullet, propelled onward through the centuries by absolute unthinking fools. Everyone except a royal essentially was stuck blaming some scapegoat for problems like the king's advisors but not the king himself without getting their whole family brutally murdered. In the European case that was generally the Jews but the Chinese and others had eunuchs because they didn't have any descendants to get offended on their behalf.

They don't follow basic advice (e.g. don't shake hands, touch your face, etc), they don't close down mass events, they don't close schools "because we're not at that stage yet". The time to close them is before we reach "that stage".

its a hard but fair and valid moral question
Hey - I was the primary author of Staffjoy!

We had a few different algorithm iterations. One of our biggest learnings was that it's hard to build a generalized auto-scheduling algorithm. While most companies have similar needs at a surface level - things like local labor laws, cross-functional roles, breaks, and business quirks mean that you end up customizing the algorithm for most customers.

For the best auto-scheduling - Kronos is the incumbent, and Legion.co is probably the most advanced disruptor.
My point is that cash-flow is the issue. And most Americans pay a substantial portion of their income towards housing. What does cutting the fed interest rate by 1% do for “typical” Americans? I don’t think it reduces day to day stress which in turn causes more problems.

I don’t have a complete answer, but I feel like the answers that are given by the government are not the best answers and not the most effective use of funds.
I don’t believe this is true at all. Educate me though, I’m wrong a lot. :-)

I wonder if the extremely high fatality count in Italy is due to the hight air pollution putting people in a higher risk.
Agreed. I forget VSCode is an electron app. I do not forget that MSTeams is.
Not to be a downer but the opposite could also be true. The less economic activity, the less particle emissions. While those particle emissions eventually contribute to global warming, they actually prevent a rise in temperatures in the short-term by blocking sunlight. Like you mentioned, the highs are higher and the lows are lower.

We could actually see an acceleration of some of global warmings' effects on the climate as temperature peaks increase.
Electors have extremely short-time memory and are in most part deeply ignorant. Moreover, at the time the next UK elections will come, there will be enough "fresh" new elder people to fool. BTW they can still blame China, Italy, for the disease. At that time, people will believe them. Look at what Trump did with the US. If the mayority in 320 million believed Trump then there is no way the mayority in 66 million could not believe Johnson.
Air quality in (parts of) China is much worse than any part of Europe, even northern Italy. To be proportional, deaths in China would need to be a magnitude higher. On the other end of the scale, Switzerland would need to be almost free of fatalities, etc.

You also don’t have much of a model. It would be strange for one virus to show an extreme sensitivity to existing environmental lung damage when all our experiences show either linear or at worst multiplicative compounding.
It seems like this is a drop in the bucket in the grand scheme of all the pollution that’s happened over the last 150 years. Is it reasonable to expect a lasting effect here?
I have exactly the same model and I had exactly the same experience. I was mesmerized by the device to see how it would reach my entire apartment following really simple algos.

Also, I also had very little expectations in the beginning (just a bit less dust) but it did really amazing job.
Yup. Small businesses don't need auto-scheduling. Enterprises already have functional tools that are hard to displace (particularly due to internationalization, localization, and payroll needs). Mid-size businesses often need the customized deployments of enterprises, but don't have the budget.
I understand WAI for articles and "document" web pages, but does anyone who uses these technologies use them on web apps? Is this even remotely the audience for most of these SaaS SPAs?

What does wearing a glove really achieve? You can't get the virus through direct skin contact, so virus living on your skin is not going to infect you. Touching your face while you have virus on your skin is how you get infected, and touching other surfaces while your hand is dirty is how you help spread the infection. Both of these work just as well if the virus lives on a glove rather than your skin.

So no, gloves are entirely useless for protection from this kind of virus. They are much more useless than masks, which could at least temporarily prevent some amount of virus-filled water droplets from reaching your nose.

Yes you will get events outside the norm, it is not the single events but the whole period average you need to look at, like looking at a single day or week of weather note and remembering the whole period around that single event. Yet the whole winter period would be warmer. Then you can have one part of a large country have it colder than normal and yet the other parts has it warmer and the average for that whole country being warmer, yet for those in the colder part they will disagree.

I don't think this is going be as short term and will certainly playout throughout the year at least.

From what I understand, this method has the potential to be a useful detection system for certain viruses (including Covid-19 coronavirus detection) and other environmental uses.

Importantly, it could likely be implemented in low-cost open-source designs.

Ask HN: What's the best software for communities to co-ordinate?

We are organizing a Mutual Aid group for our community to help any elderly or families who have to self-isolate due to the ongoing COVID-19 outbreak. We are using WhatsApp to communicate, but I wonder if anyone has any suggestions for how a group of individual volunteers can co-ordinate with each other.
Inside of governments and corporations are individuals making all of those decisions. There is a buck and it stops with an individual on a decision, or a couple of individuals at most.

I think the situation may be a little more complicated than that.

For US$10k you can buy 28 brand-name Prusa Minis or 50 off-brand knockoffs on DealeXtreme. If a part takes three hours to print on one of these FDM printers, as you're suggesting, you could print 2500 of them in a week with your 50 off-brand knockoffs; if you can get the printing time down to an hour, 8400. And, unlike with an injection-molding machine, they come out of the machine sterile, and PLA is biocompatible and aquadegradable, implants having been one of its few significant uses prior to its uptake for FDM.

Such FDM mass-production is in fact how Prusa produces a lot of the parts for its printers. Aside from sterility, it has some other significant advantages over injection molding: its dimensional tolerances, shitty though they are, remain stable over the entire print volume, so you can get a 200±0.1mm dimension on your part on a typical cheap FDM printer; and the parts you print are much ligher in weight, due to the standard honeycomb infill, and (though this is not relevant in the case of duplicating an injection-molded part) they have much more geometric flexibility than injection molding — they can include voids and enclosed spaces, and even preassembled mechanical assemblies.

The article says that after the initial FDM parts, they switched over to SLS, which is a faster and more precise 3-D printing process which can also process metals, although in this case they were doing plastic SLS. SLA is another higher-speed, higher-precision 3-D printing process, and both SLA and SLS can produce several parts at once for a further gain in speed.

On the other side, I hear it's common to have to go through three or four revs of injection-molding dies before you get to the rev that works properly, and it's common for that to take months. Maybe that's a problem that can be avoided by sacrificing something else, like cycle time or die durability; do you have experience in the area?
Ask HN: Tinder for scientists seeking developers
When I have downtime I enjoy solving problems. The scope of my experiences being startups, and some dipped toes in medtech means that the problems are often technical in nature. A faster X, a statically compiled version Y.

Lately I've been wondering if there are projects I could be contributing to that could help my local medical facilities or a tool that an epidemiologist dreams of and doesn't realize could be a reality.

I'm getting about 2.5 bn op/s, which suggests this is rather down to the JIT's ability to elide microbenchmarking code.

Edit: Worth pointing out that the linked page runs on an eight year old version of the "benchmarkjs" package, which is described as a robust benchmarking package, but while the linked blog posts discusses some issues with JS benchmarking, how to trick the JIT into actually still running your NOPs is not discussed.
IMO what DO offers is ahead of Elastic Beanstalk and GCP App engine in many ways. Instead of offering a single service they have opted to provide easy to install images for deploying services. These days if I wanted to set up a small service on DO I'd simply go to the DO marketplace and click a button to launch a docker instance. For a larger or more complex service I'd probably opt to use DOs kubernetes support, it's similarly a couple button presses to boot up a cluster.

In either case I can then just point kubernetes to the right address and get going with spinning up my application.

It's a bit less polished than what elastic beanstalk or app engine provides, but it is a lot more flexible without being more complex. If anything it's a lot simpler than any of AWSs offerings because DO actually has a sane dashboard unlike AWS.

I can't comment on app engine since I haven't used it but I can heartily say that the last day I need to touch that abomination of an AWS dashboard is the day I'm having a party.

This "prep work" is selfish and irresponsible.

Supermarkets / grocery stores are not closing. There are no floods or storms or nuclear bombs falling, preventing people to go to supermarkets.

If many paranoid people start "prepping", they empty out essential stuff from the shelves. Then an older, poorer person, who is out of TP / canned food / etc. goes to the store and finds nothing there. That's honestly saddening.

This is a matter of altruism. Western countries, especially America, is thinking selfishly. I like capitalism, but this is a bad aspect of it.
Can’t speak for others, but in France, you are partially responsible of the loss of your company (for example).

My wife and I are married with a full separation of goods and possessions contract. Not because we don’t want to make financial choices together, but more to protect her for the possibility of me being ruined if my company fells.

When she was working, we agreed on the money we each put in the family budget for groceries, kids stuff, etc...

I really do hope that this event will give a big blow to the mass-tourism industry. It doesn't feel right to catch a flight from Europe to half-way around the world (Thailand, let's say) for just a few hundred euros, there are lots of externalities not included in that price. To say nothing of the Dutch-disease-like effects brought by mass tourism to those tourist places.

He's desperate to stay president, probably because next stop is prison (or maybe not, the rich and powerful get away with everything).

As a non-USAian, I can really see that he doesn't give a shit about the rest of the world, because the rest of the world can't vote him to stay in or out of office, but can be used as a base for his performance, for him to brag "Look how I delivered".
