I'll only buy food that is in containers and clean the containers with a cloth with soapy water. Hopefully, soapy water is suitable. If I'm lucky I'll be able to get methylated spirit in the grocery store to make methylated spirit 70%. This concentration is mentioned in [1]. I could then fill up the empty bottles of surface disinfection spray that I've collected in the last year.

That would be a major undertaking given the size of the warehouses involved, would almost certainly interfere with the flow of packages somehow (which, unless it somehow speeds up logistics, makes it a non-starter,) and it would cost money that I guarantee you Amazon doesn't want to spend.
It depends on what you mean by checking all the boxes:

Go is tricky if you run on diverse platforms and want to do a lot of FFI, since cgo overhead is significant. The type system in Go is also not very powerful, which is both good and bad.

Haskell tends to hit performance walls that are very difficult to debug, and has a pretty similar learning curve to Rust (most people you hire onto the team won't know the language already).

The predominant competitor in this space is probably a high-level dynamic language combined with C/C++ library code. With good tooling and good practices to mitigate footguns, the extensive library support in C++ has a lot to offer.

Of course, I think Rust makes a better trade-off there, but early in the project it was not at all obvious that the good parts outweighed the fact that we would probably have been the biggest user of any library we depended on. We had some fun adventures in stress-testing HTTP/2 support here :)

The rental payment from a shop is income for the landlord. The income from the landlord is payment for his/her obligations - all the way up the chain.

If you force rental payments to stop, then who gets hit? The landlord is going to default on their obligations. So do you then bail them out? If the landlord defaults, the banks (presumably) will repossess the property. So it's just somebody else suffering, rather than the tenant.

The loans work, because the obligation to pay back this loan will come from a future where you have the capability. The govt is the eventual guarentor of this loan, and hence, they take the hit if the eventual future does not come to pass (e.g., the restaurant never regain their full business). The gov't can't take the full hit of all these defaults all at once, but they can if it is spread out. So a loan will spread them out into the future (even perhaps, far future), and the economy survives, even if a lot of the business that took the loan didn't.

EDIT: The earlier coverage included this quote: "What’s essential about automobile manufacturing in the midst of a viral pandemic? “That’s a good question,” said spokesman Ray Kelly, promising more information would be forthcoming. “We’re in uncharted waters right now.”"

There are different ways to interpret that, but they seemingly were not confident at the time. Still a strange way to "correct" it, though.
In this case, direct comparison between countries' responses is not so practical because the Western countries don't have the SARS experience, which led to the seemingly out of proportion responses like here in Hong Kong from the beginning.

For instance, a significant portion of our medical staffs went on strike when our pro-PRC government officials refused to clamp down the borders, and we were part of the gang who scooped up face masks worldwide.

Also, WHO seem to be downplaying the risk all along until recently.

The principle of ceteris paribus needs to be considered.
The barrier of entry for a company like System76 to make a mechanical keyboard is suuuuuper low. Just look at the Code keyboard, WASDKeyboards, or even a company like Razer (they've been at it for a long time). Lots of enthusiasts like myself design and manufacture very low run keyboards as a very addictive hobby.

PCB design is dead easy with tons of examples to work from based on simple, cheap ATMEL USB controllers (and Arduino compatibles). Prototyping is possible without a PCB, though quite labour intensive. PCB prototyping is pretty cheap as well, as a keyboard can easily be just two layers. Switches are plentiful and cheap with tons of selection and competition now that's Cherry's patent is long expired. Keycaps are easy to acquire in volume in a variety of materials. Case design is probably the trickiest and where most of the cost lies. An injected moulded case would be the cheapest per unit with high upstart costs, whereas CNC'd cases are pretty expensive. The bent metal case (as part of the plate) is pretty much the only low volume way to build a cheap case, but I think it doesn't look great.

I'd love to see System76 use Kailh's (aka Kaihua) low profile switches in their beefier laptop designs or even just in slim keyboards. If they copied IBM/Lenovo's old school profile and layout I'd be over the moon, but that'd be pretty expensive to get started and likely fraught with patent crap.

"Monoclonal antibody" automatically means $50-150K per course of treatment pretty much. And while that price does not reflect the actual cost of just producing the drug, these drugs are legit expensive to produce as well, just not to such an extent.
People are quibbling about money while millions of lives are at stake. We need tens of thousands of these medical devices and we need them fast. Like in the coming weeks.

If companies who suddenly find themselves in a strategic position don't get what they need to do, then the Government needs to take control using emergency powers, and use any available production capacity in the country to ramp up production, fast.

We'll also need to do many other things. We should adopt a wartime mentality, focus on solving the problems at hand, and stop wasting time. At least in Italy they get this now.

It’s kinda easy to see why inflation is limited to certain sectors — “trickle down” isn’t working! CPI rises only if the money reaches the hands of poor(er) consumers who spend all their money on essentials. But currently the money is being made available largely to large corporations (etc) who can borrow at low interest rates — and they’re choosing to spend on financial assets — which is where we note the “inflation”.

Seems like this can be produced much faster on a CNC. 3D printing of large parts is extremely slow.

That said, I'm not even sure this is useful at all in practice, since I'm not a doctor. This needs to work on an intubated patient, and be able to maintain a sanitary environment, neither of which it'll probably be able to do to the extent required by health and safety regulations. But I'd love to be proven wrong by someone more knowledgeable in this case.

Ask HN: Long Term Impact of Widespread WFH Culture?
Now that companies are learning the hard way to WFH, and were seeing memes like “now we’ll know which meetings could have been emails,” does it concern you all that the next logical step is to double down on platforms facilitating a WFH culture during the inevitable recession? The last recession in 2007 saw very slow job growth (compared to other recessions) simply because companies opted to adopt technology rather than train+hire expensive labor. I fear that the next leap will be widespread prioritization to set up satellite offices in India and other countries where labor is cheap. If I were a Fortune 500 CEO, my top priority during the coming recession would be to offset the lack of H1Bs in the US and just go straight to the source- because I know every other CEO would be doing the same. I fear for my future prospects a year from now.

We probably need good tutorials about how to create a nice looking HTML pages. Pure HTML, maybe with CSS. I'd prefer page to be self-contained - a document, not an app. This way some accessibility problems could be avoided too.

At least we may have static page generators which execute JS once on server side - for pages which don't really need interactivity (documents, not apps). There are a lot of them.

The demos run over a shared instance of a server with fixed resources, so I wouldn't count on it being the most stable experience, especially if it becomes popular enough to saturate the machine's resources.

There are no shortages when gouging is allowed. Gouging disincentivizes hoarding. See my other posts in this thread.

I totally agree with you... but in the case where there are no respirators available at all, I'd rather have a 10% chance of secondary infection or contamination than just die.

I don't see a device like this as being a replacement for a $50k computer controlled machine, but as a stopgap in desperate emergencies.

Dynamics of Particles and Rigid Bodies by Anil Rao https://www.amazon.com/Dynamics-Particles-Rigid-Bodies-Syste...

Dr. Rao’s systematic approach to solving dynamics problems is consistent and concise. He also has a companion set of lecture notes on YouTube. I remember it as one of the most challenging but rewarding aspects of my engineering school experience. All the principles are described mathematically in a coordinate-free manner. You’ll learn to set up equations of rigid bodies and constraints without all the guesswork and haphazard construction of coordinates typically encountered in a physics textbook.
I'm not sure of the source for this, I've been reading a lot this week...

Someone with more knowledge could expand on this, but I understand that wearing a mask in south east Asia is a social signal that the wearer is aware that they are contagious and are using the mask not for their own protection, but for those around them. This makes sense with surgical masks that are designed to keep things _in_ not out.

Culturally this is counterintuitive to the west where we typically value the individual over the collective. (Probably an over-broad generalization)
If you want to get an intuition for the weirder curvatures of 3D space, there's a playable "curved space simulator" created by topologist Jeff Weeks called Curved Spaces.

Where does this meme that companies get sued for parts made by completely independent third parties come from?

The most obvious reason that wouldn't be true is that without a patent on the part or similar, companies generally have no right to prevent third parties from making replacement parts for their equipment. It would be pretty silly to impose liability for something they have no control over.
Nit-picky reviews are a smell, not a good thing. It can often mean that the reviewer is not really reviewing the big picture (is the intent of the change being fulfilled, is this the right place in the architecture, etc) and it making up for it by focusing on irrelevant details.

Seriously, code review on punctuation in a comment is not good in any scenario and it speaks nothing to the legibility of the code itself. If anything, it might mean the code is unreadable and the reviewer is too embarrassed to point out that they can’t follow it.

Having typed it out, it's sorta odd that there's a screensaver at all, rather than just always acting like it's up and running.
