Of course, but that's surely not what Daimler's CEO was suggesting. What he might have been offering may be assembly workers, or factory space, or privileged contacts with Daimler's supplier base, or something else. My point was that it would be interesting for the general public to understand the actual issues. Right now we're all left guessing a bit.
A surgical mask isn't a N95 mask.

Spacex could be in trouble too.

Cars are many orders of magnitude more complex than ventilators so it's not unimaginable. A ventilator is basically a motor/small turbine connected to a few sensors and air filters, all linked together with some fairly sophisticated software. The software can obviously be 'manufactured' at infinite speed. That leaves an assembly of pipes, valves and flow sensors - but only a few. Especially if you customise the machine to only what COVID-19 patients need and don't go general purpose, it can be done.
The second option, of course.

The industrialists I mention are not just in automotive, but oil and gas, etc
Our experts said not to use face masks. There's a debate of whether to listen to the experts.
Some psychotic Govenors are even trying to block hydroxycloroquine from being used because Trump mentioned it. If it works it works all Trumps aside.
>Nikon cloned it, then replaced the viewfinder with Single Lens Reflex system

As far as I know Nikon started off making Contax clones, not Leica clones. Canon did Leica clones, though.
Keep in mind that Leicas up until the M3 didn't have a combined viewfinder/rangefinder. That was an innovation from Zeiss first used in the Contax II.

And there's been quite a few SLRs before the Nikon F, it was just Nikon that made it so solid and efficient that made professional photographers switch from using a rangefinder to SLR.
>I'm not betting on anarchy, but on the emergence of form of a way of organization that is able to operate with bit of disregard of entrenched power structures by co-opting those who work for them yet don't feel they receive enough benefits from the current situation to uphold a particular institutions beliefs, and willing to explore the horizon for more options.

Sounds like a religion.

>while others can simply walk out the tent, and construct/decommission a structure that which they choose for any particular ends, and walk in/out of the tent and leverage its resources as it sees fit and work with others who share similar goals against those can not imagine any other way of being. I think a good example of this is with regards to academics and shared credential usage that enables sci-hub. I see a similar situation unfolding in banking right now.

The problem with this is that the people who are privileged to be able to walk in and out tend to feel entitled to the tent because they have access, but not obligated because "they can leave any time," not observing that their lifestyle still requires the tent and the people living under it.
We have totally given up on obtaining N95 grade masks?

The masks you are talking about, we already have citizens sewing them in a large-scale volunteer effort.
I grew up in a rural area. We had dial-up for years until we got point to point wireless, which capped out at 1.5 mbps. 3 of my team members live in a rural area and have similar internet. They’re all waiting to throw money at spacex as soon as it goes live. There’s millions of people in the US like them that would sign up. My wife and I are planning to move further from the city, but one of our concerns is getting decent internet (we have symmetric gigabit fiber now).

Also I don’t think you truly grasp the cost efficiencies spacex has and will achieve. Elon originally said that they could lower launch costs under $1m if the only cost was propellant and minor refurbs, compared to hundreds of millions. Even today their confirmed cost is 6x less than average [1]. This is not a 20% reduction or something. It is incredibly significant. one web was launching on other companies’ rockets, so that’s an additional disadvantage since spacex is only incurring the cost of the launch and no margin since there will be recovered from the internet service.

Surgical mask, not N95 as stated in the editorialised title. Additionally they noted that it was hard to breathe through this improvised dishcloth mask.
No, the debate is how to recognise the experts.

> If you think knowledge of CS fundamentals is what is separating the hired from the rejected...

I've never stated that. I am aware of the other behavioral tests if that's what you're referring to. But the fact remains that they give you algorithms questions that we dont use in most of our daily work and if you can't meet the rather high basics you are rejected.

> And there are IQ tests/proxies that are entirely “verbal” like the GSS Wordsum - what is your point?

That you can have IQ tests without knowledge prerequisites unlike what you stated before the edit?

Well either you're BS-ing or you've been confined to some kind of corporate environment where they've somehow convinced management people (who dont code) to adopt a test so detached from reality.
These are lab experiments. The people running, configuring, and setting them up neither have the expertise nor the time to set up such a system.
It would be nice to have a compiler option, that would deprecate things from earlier standards, that would work per file or per pragma block.
I'm several years into the "upgrade" and find myself still swearing daily at the idiocy of the whole thing. Hundreds of scripts used maybe once a year, such as 'dups.py' I tried to run today, broken by a missing parenthesis, and a function moved around.

Utterly pointless and reputationally ruinous. I don't do serious work in Python any more
> Internet is a commodity for the average person, you can't make money in that market.

This assumes that razor thin margins are bad, which is usually a safe assumption but in the case of Starlink, I say it's not open minded enough.

To boot Starlink online requires a minimum cost for service area (sats), but once you've got that area booted, onboarding new customers is trivial (vs laying fiber, cable, digging holes).

The user terminal is for each individual - "Looks like a thin, flat, round UFO on a stick."[0]

Note that the UK spends a lot less (per capita) on healthcare than Germany: (£2,989 vs £4,432 in 2017), and that funding for healthcare has generally be considered to be insufficient over at least the last 10 years in the UK, leading to cuts in service. This may account for at least some of the difference.

You should wash them, soap seems to be very effective against Coronavirus.
What is "special" is that the system has a peculiar property: f(x) != f(x).

If we claim to be subscribed to denotational (Mathematical) semantics then the above contradicts the identity axiom.

And it's not any deep and world-changing insight either - it's obvious to anybody who sees that the LHS and RHS are only evaluated at runtime - they don't have any inherent (denotational) meaning, which is why I keep harping on: programmers use different semantics to mathematicians.
We care about things like interaction and control flow structures as first class citizens - those are precisely the things that have no mathematical equivalents. Timeouts, exceptions, retry loops.

It's not "syntactic sugar" - it's necessity for reifying control flow. In the words of the (late) Ed Nelson: The dwelling place of meaning is syntax; semantics is the home of illusion.

At least car manufacturers consist of more than one production line. They make smaller series and prototypes too. And they have lines (and suppliers) that supply parts to other lines.

Remember they also have to build the ECUs, dashboard and AC plumbing. If you squint that might be about what you need for a ventilator.
This is basically a desktop system running a lab experiment. After the pop saying 'reboot in x hours' we changed the group policy, however this does not stop a pending update.
I'm an HPC developer, my workstation is a 122 PetaFLOP machine.

I go to the Rust language website, and I am able to understand in 1 minute what's the language for, and what value it adds with respect to the alternatives.

I look the Chapel website, and I get nothing. So I have to guess, and my guess is that's a framework developed by one research group to publish research about parallel computing, but that almost nobody uses for anything real in practice - except for the one or two simulation tools that they managed to lock-in 10 years ago. It's not clear to me which value these adds w.r.t the alternatives, like pure MPI+OpenMP, HPX, Fortran co-arrays, and the other dozens or hundreds of half dead research projects that were supposed to "revolutionize" HPC over the last 4 decades. The sad part is that I'm probably right.

The 3 most used languages in "classical" HPC are C, C++ and Fortran. Python was barely used, but now the recent trend of building "AI" HPC national centers have put it in 4th place. The three most used parallel programming paradigms used are MPI (which a dozen of implementations available and in active development), OpenMP, and CUDA. The amount of people that use OpenCL in classical HPC is insignificant. There are more widely-used codes using OpenACC than Intel Thread Building blocks. The users of modern frameworks like HPX is almost non-existent, and the users of things like Chapel are a signed zero. I've access to a handful of >10 Petaflop systems, and none of them have Chapel even available through their module system.

This doesn't say anything at all over whether Chapel is actually good or bad. But it is actually the job of those getting public funding payed by taxpayer dollars to advertise why we should keep funding them and not fund something else. The fact that their website doesn't even try to pitch it suggest me that the only purpose of the project is for the group that develops it to explore interesting ideas and publish papers, as I mentioned above. That's definitely something worth doing, and often decades later these ideas percolate into solutions that people actually use. But simulation frameworks that run on the Top 10 supercomputers usually take hundreds of people and multiple decades to write, and aren't something that follow trendy research frameworks.
I'm not so sure. We have an ongoing toilet paper crisis that is in it's third week now and the government is unable or unwilling to do anything about it, despite ensuring everyone that there's plenty of toilet paper somewhere in some storage of some company. If a somewhat trivial problem like coordinating a few trucks is beyond their ability, I have no hope for coordinating planes and import/export.

You might say "but that's toilet paper, who cares", but empty shelves in super markets in Germany are a great way to make people remember the past and go into panic mode.

What people do right now is buy masks individually from Chinese vendors on Amazon, and they are getting shipped. If you want them quickly, you can pay for airmail. China can deliver, but for some reason, Germany doesn't take them.
Hello fellow iOS developer. I have two apps on the Apple store. I never used any external SDK/libraries, only the built-in Xcode ones. I preferred to spent a bit more time in writing/testing but I would never accept that FB and other scum (privacy standpoint) track children (I wrote the apps for my nephews and nieces and I put them in the Apple store just for them)(I don't advertise them at all and I won't do so here either).

Regarding the issue that started this Zoom-FB dialogue I have commented a dozen (or more) times on the necessity to have a firewalled phone that a user (unfortunately the user needs to have basic knowledge of firewall admin) can decide what to allow and what to block. Your point on who audits is valid (I am a CISA and CISM of many years), and, well, nobody does. Each user will have to do his/her own work/effort to keep their family clear of these scum.
They may welcome your contribution. Hop on gitter and run it by the dev crew directly!
For that reason, additional production capacity should be subsidized by the government, but I don't see that it is going to happen in this case.
> I don't believe I am confusing important happenings to transformational changes; rather, I think you are simply denying that there was a paradigm shift.

Paradigm shifts require a significant fundamental systematic change. It mostly started out with kuhn describing scientific paradigm shifts, but can be used elsewhere. Here's one clue, paradigm shifts don't happen often. The fact that you listed 9 should be a clue that most or all of what you listed are not paradigm shifts.

> For example, you write "The soviet union existed before ww2 and they were a dominant force before ww2." ... you will fall back on the position that what actually happened did not amount to a transformational change.

I was pointing out that soviet union existed before and after ww2 in pretty much the same position. Also, we are talking about the change of the global world order. You seem to be fixated on individual countries and are completing missing the point.

> Your argument so far has been a combination of non-sequiturs (such as mentioning the moon landing)

It's not a non-sequitur. I was just pointing out important events happened. But those important events don't change the international world order. Vietnam War, Iraq War, etc happened. Didn't change the international world order.

> At this point, you owe us some examples of truly transformational changes.

Once again, we are talking about transformation changes of the world order, not single nations. Since the "world order" is a fairly recent invention and hasn't changed, I'll give you localized historical examples.

The ottoman turks conquest of byzantine empire.

https://en.wikipedia.org/wiki/Fall_of_Constantinople

The mongol conquest of china, middle east, russia, etc which shook up the geopolitical eurasian order.

The treaties of westphalia which created the sovereign nation-state.

You know significant events which actually changed something.

The world before ww2 was a "western" world order. The world after ww2 was a "western" world order. The same people running the world before and after.

I think the confusion here is that you seem to be talking about changes with individual nations while I'm talking about the world order.
The creation of israel, north/south korea, south sudan, etc are important to those nations, but didn't transform the world order. These nations all live within the established "western" world order. But if you feel different than you are entitled to it.

The opening of china was an important event, but didn't cause a paradigm shift since they decided to work within the "western" world order. If china ever challenges the current world order and decides to create their own international system and does so successfully, then a significant world transformation would have happened. A world led by china with "chinese values" instead of "western values" would amount to a paradigm shift in the international world order.

WW2 didn't cause a "transformation", it actually cemented and reinforced the pre-ww2 status quo. Once again in terms of the global world order, not individual nations.
Half Life Alyx is built on Source 2, which was extended from Source 1, which is a heavily modified version of GoldSrc which was based on the Quake 1 engine.

This kinds of activities have been going on at least since Digg.
This research, of course, has implications for volunteers who are trying to make DIY masks for health care providers, to use as a last resort.

But I think the broader message should be: Wearing a mask in public, regardless of what material it's made from, is better than nothing.

It offers at least some protection to the wearer, and it also offers at least some protection to people around the wearer.

In several Asian countries, it is totally normal for people to wear masks in public to protect themselves and others from infectious diseases.

Perhaps this pandemic will help normalize the practice in the US. I really hope that resistance because of dumb cultural factors doesn't lead to more severe outcomes. Sure, bud, you look silly in a mask, but better silly than on a ventilator.

Every process can already be automated, it's just a question of whether someone wants to pay for it.
> Do you really think they prepared a PR statement to respond to harsh criticism and just decided to toss in there the list of information sent without crafting the order of the items?

Yes, because it's in alphabetical order.

You don't have to craft anything for it to be in alphabetical order.

You just put it in alphabetical order.

The sorts of people who are going to read that list and understand any of it are the sorts of people for whom the order doesn't matter one iota — they will see the information.

For the majority of people, putting it at the top of the list would, equally, not matter one iota — they won't know what it means.
If you're interested in the complexities associated with retrofitting CPAP machines, I've written a couple of articles about it:

https://blog.plan99.net/cpap-for-covid-d47886bf978c

https://blog.plan99.net/more-cpap-for-covid-b6911f806c89

The primary difficulties are establishing medical consensus on what kind of pressure therapy is best (continuous vs bi-level) because that affects the availability of machines a lot and there's some disagreement. Secondary is how to stop patients on CPAP machines spraying virus into the air through the masks, however, at least one CPAP machine manufacturer thinks that concern is actually overblown and points to a study showing CPAP masks don't aerosolise to the extent current medical consensus seems to think.

Something very clear is that doctors are still figuring out treatment for this and there's some disagreement over what the right way to do things is. Disturbingly it may be that current medical consensus makes things worse for COVID-19 patients rather than better i.e. bi-level pressure therapy hurts the lungs in that state rather than helps (perhaps contributing to a high death rate?).

Intel Ramping Up Their Investment in Blender Open-Source 3D Modeling Software
Me and my girlfriend like to travel. Sometimes we just like to go away for the weekend (flights are cheap in the EU). Airbnb was a perfect choice. It was cheap, we can meet some locals in their house and get genuine tips only locals know.
Once we stayed in Malmö. The flat was a little bit messy, there were two little (under 10) children in the flat, so it was noisy. In the kitchen there where breadcrumbs everywhere. We still very much enjoyed our stay because the place was cozy our hosts were friendly. This was our "worst" experience when we stayed in a spare room.

In recent years we run into more and more listings where somebody renting out the entire house, each room to a separate individual. Sometimes it is indistinguishable from the former one before you arrive. If I staying at a "hostel" I want my bathroom and kitchen cleaned every day, but most likely I would just choose a real hostel.
(Not an expert on ventilators, but I have been working on software side of medical devises.)

Producing semi-mechanical Bag-valve-masks (BVM) would be relatively easy, but you need professional to sit there and monitor the patient. That's not ICU ventilator. BVM is very crude tool for short term use. If the rules and legislation are relaxed so that hospitals could use non-certified crude devises that help. You would almost certainly see ventilator-induced lung injuries.

Ventilator-associated lung injury https://en.wikipedia.org/wiki/Ventilator-associated_lung_inj...

Ventilator-Induced Lung Injury Review (Part 1 of 2)
https://pulmccm.org/review-articles/ventilator-induced-lung-...

If the system is automated life support, it generally has to maintain homeostasis of the patient and _dynamically_ adjust. If you are just tiny amount off from the optimal and there is drift in the dynamical adjustment it accumulates over time and you can kill the patient or cause immense pain or discomfort.

Oxygen is poison if you get it too much and if you get it too little, you die. Pushing air into the lungs can damage them and the oxygen mix should adjust. If lungs are filling with fluids, you might need more oxygen and less volume. The system must be connected to instrumentation that monitors the patient's state continuously.

There is the question of medical staff using the thing correctly. Medical UI/UX is safety critical in the same level as it is in aviation. If just 5% of users use it wrong it, can negate all benefits from using the device.

Generally you need deep knowledge transfer to scale up production of critical components or testing and calibration, just emailing the specs is not quick enough. You need to test it with real environment and refine the device to see how it works in practice. I'm sure that ventilator manufacturers have already outsourced every component that is easy to manufactured and produce to others. There are some bottlenecks that involve testing, special machines, materials and calibration that is not easy to scale quickly.

(edit: the time-frame of ICU overflow seems to be between May-Sep in the most countries in most models If you ramp up deliveries 3 months from now, you could catch the tail end of the need)
