Hi, I'm a physicist and former IPhO contestant from Hungary. Unfortunately most of the books I could suggest are Hungarian, but there are some resources in English for hard physics problems.

KoMaL [1] is a high school competition, students have one month to solve five physics problems (they can solve more, but only the five best is counted each month). Unfortunately older archives are only in Hungarian, but this is an endless resource, you can come back for new problems each month.

Ortvay [2] is a yearly take-home, one week long problem solving competition for University students. These problems are _very_ hard, so don't be discouraged by not being able to solve them right away.

[3] and [4] are some of my favorite books with Physics problems from Hungarian authors. The problems have varying difficulty, but they are clearly marked in this regard. There are separate hints and full solutions.

Didn't Dyson move all his manufacturing to Singapore at the same time as loudly espousing Brexit?

Waiting for the v2 of the ventilator that has a ball attached, and costs an extra £100.
withouth a meaningful time line, this is all noise.

its a totally new design, which means its going to have to be re-certified.

The UK has had 2 months head start, 1 month if you take italy as a warning, 2 if you treat the "YOLO LETS JUST LET IT BURN THROUGH THE POPULACE."as a starting point.
Dyson and others efforts are additional to the two ventilator manufacturers in the UK, who have already received orders for about as much as they can produce.

From the article: "...the government thinks it can procure a further 8,000 from existing domestic and international suppliers"
I am finding it very interesting to read the disparaging reaction to this measure by the Canadian government, and the reaction to a similar measure taken by the Israeli government.

I think Nim also has digit separator.
Mind bending. Hope it's a one-off case.
There is a separate, co-operative effort by a consortium of manufacturers to improve and mass produce an existing ventilator design.

But with a project of this importance, while it makes sense to pool resources, you can't realistically have every company and every engineer co-operating on the same project. So it also makes sense to have several, independent efforts running in parallel.
"under two and a half hours" per test. To be able to make 10 tests per day, you'll probably can't have any delay between tests : 1 day = 10 x (2 hours + 24minutes).

If accuracy is an issue, why not doing a two pass procedure ? 1) test quick and cheap 2) if results have low confidence, move to longer/more reliable testing method
I read this the other day[1]. See challenges listed in the middle. It does seem like it's not very easy at all.

I was thinking it might be nice to be able to have an HMACed token with an expiry as an option - so e.g. my main http-serving thing could provide one of those to allow the frontend to read for a bit but kick the user off after half an hour or whatever if the token isn't refreshed.

I've no issue with offloading SSL to a different process though, I tend to prefer doing that anyway a lot of the time.

Email is a bad tool for discussion.

However, it can be a good tool for information dissemination. (There are better tools - I'd argue that sending information should be pull rather than push, but that's just my preference).

So yes, have a guy write something down for 30 minutes, get people to read it, and then have an actual conversation / chat about it.
it does, when you take into account the turnover of existing accurate test methods and their accessibility

This does make sense. Every company that normally doesn't produce ventilators but wants to make lots of them fast must repurpose as much of its existing tech (production lines, parts etc.) as possible. This requires intimate knowledge of private tech, which only internal teams have.
It's really in response to a confused, ad-hoc web privacy model that has never been designed and is simply incrementally patched over time in response to complaints from an equally confused, directionless and visionless 'privacy warrior' subculture.

Mobile apps suffer these kinds of problems far less, partly because it's understood that actually mobile users don't install apps then get upset about "tracking", in fact, the vast majority of apps will want you to sign in to some sort of account and those that don't will be using ad networks to fund themselves, that users understand and accept this and that throwing up permissions screens doesn't achieve much because users will typically grant the permissions. Privacy on mobile platforms is more about stopping activity the average user would recognise as illegitimate spying - turning on cameras and microphones to feed conversations to angry ex-girlfriends, that sort of thing.

If the web's architecture had some sort of coherent view on how the tension between users, content providers and advertisers should work, then we wouldn't see this steady endless churn of app-breaking API changes. Everyone would know the rules of the road and there'd be way less tension as a result. Mobile platforms aren't quite there because they were designed with security architectures that were then pressed into service as ad-hoc privacy architectures, but they're still far more coherent on the topic than the web.
Don't current testing machines have much, much higher throughput? Like in the thousands of tests per day? It seems the advantage of this new device is latency. Of course if they are cheap enough and easy to use that you can buy thousands of them and distribute to all hospitals then might also increase total throughput.
The full quote is "A Bosch Vivalytic analyzer can perform up to ten tests in the space of 24 hours. This means it takes just 100 devices to evaluate up to 1,000 tests per day." which makes more sense, the 100 devices is just an example.

But I agree that it's largely unnecessary, the initial "up to ten tests per day" would have been enough.

Whatever his views on Brexit (and I am Remainer), I think credit should be given to Dyson and his team - they are going to be manufactured in the UK and he is paying with his own money for 4000 of these ventilators to be donated to other countries:

I'm curious how they managed to get in contact with STM. I once discovered a silicon error in their STM32F0 but failed to get in touch at all.
It has to fit their manufacturing process.

Which was likely the bulk of the man hours. Taking a spec sheet, and figuring out how to make it work with existing tooling and processes so they don't have to wait to retool the factory.

So are ventilators actually complicated and frequently modernized equipment or medical TI83s. I was reading one the largest expenditures of PPEs in China after they resolved the supply issue was adjusting ventilator settings. Seems like a wired or wireless interface would go a long way.
Pranks are difficult to do right. They easily can be experienced as frustrating, aggressive or plain idiotic by the receiver while the giver thinks it's totally hilarious. It requires a lot of empathy to create a good prank that doesn't hurt anyone especially when it's experienced online, ie. without being able to interact with a "WTH man?! - Sorry, tried to prank you but it misfired. You OK?"

In the good pranks category, I'm especially fond of new product announcements when it's clear it's a joke like Amazon shipping authors directly or the Google's "Clean screen" app. They are often refreshing and witty and it's just what I want from a good joke. And it's free positive marketing if done right. (Just don't announce your company bankruptcy, like Elon Musk.)

Is it, too, going to use 15% of CPU when doing intensive tasks?
It’s a really small device as far as I understand, so you could use it in a small practice or even on the go (?). This can be an advantage as most of the lab systems weigh several tons and take up a lot of floor space, hence you can never use them in a decentralized setting.
It's nearly impossible to grow up in Western culture (no experience with others) and not have some extremely basic Asterix-level understanding of what the Romans were and when they lived.

And that they basically copied large chunks of their own culture from Greece which invented democracy a few centuries earlier.

I mean, even Christian fundamentals have that context based on their lecture of the Christ saga.

It's all fundamentally what our own culture is based on in the West, just look at Washington DC and the buildings. Or Wall St. The Greco-Roman influence is permeating the West.

From what I understand, Dyson is not trying to "design a perfect ventilator." He's trying to design a cheaper, easier-to-produce ventilator that will be good enough for many situations, vastly improving the availability of ventilators for all who need it.

Everyone else seems to be just working on producing the existing, hard-to-produce ventilator.
I've seen ES used for meilisearch's precise use case quite a few times before now.

So it's not "an alternative to ES in general", it's "a thing designed to be an alternative for a subset of ES use cases", and the comparison document is pretty clear about this.

I've been taking a similar approach and pursuing this topic by getting into Computational Fluid Dynamics and understanding physics in code first, then trying to bridge the code to the more rigorous mathematical representation.

This is after I tried reading a bunch of physics books and, while interesting, I couldn't really get my head around "Ok, so how would I program something like that?"

But then there's this, you might find it interesting, it helped me understand how everything fits together a lot more: https://github.com/barbagroup/CFDPython

Also, physics is a big area, so this is just one part, specifically the physics of fluid simulation. But there's a big market behind CFD too, so you could do worse in picking something with some directly practical application.
I was being slightly facetious knowing the crowd round these parts.
Thank you for confirming this!
For an Cortex M0 the clocks default to something sane. And RAM is static. One of my projects the reset vector is just the address of init function written in C. That does nothing more than copy the data section from flash to ram and call _start()

There is a bunch of peripheral set up but it can be done from C.

G-7 drops joint statement on coronavirus following fight over language
The problem with BCE is largely that it does not fit with the paradigms of ncurses and terminfo, not that it is problematic in itself. This is alas true of a large number of terminal things, from function keys through "cursor addressing mode" to erasure, whose ncurses/terminfo abstractions do not fit the actual ways that these work.

On both real (DEC) terminals and terminal emulators, background colour erase is settable off and on, with DECECM; so a full-screen application can set the behaviour and know what the colour is going to be, leading to more efficient screen redraws. The ncurses/terminfo model, in contrast, is that the behaviour is fixed on or off, and a boolean (named bce) in the database tells softwares which it is for any given terminal type.

In reality, it is the paradigms of ncurses and terminfo that are the problems here.

On that topic, I really like David Allen's "hierarchy of communication channels" (name is mine) in Getting Things Done. He says that when you need to discuss something with someone, you should consider the following communication channels, in that order:

- e-mail

- leave hand written note on desk/in pigeon hole

- send IM/text message.

- put topic on a "list of things to discuss i next meeting"

- phone call/face to face

You should choose the first that fits the urgency of the situation. The idea being to maximize trackability and minimize disruptions. In the current Slack culture, I actually put IM just before phone call, given the expectation of quick answer most people have.
This sounds convincing. Though Dyson’s products do not have much in common with medical equipment. Hair dryer or vacuum cleaner has other power level than ventilator for the lungs.
> Doesn't `getrandom(2)` use `RDRAND`?

Thanks for being honest. Many here are in denial or are at best just fair weather liberals.

This being said, we are at the beginning of this, so it's more likely to be a temporary state and that things will return to normal than we enter a state of always being at war against covid19.

But this event will make many people wonder about what people will do if you convince them enough. The thing doesn't need to be true or not, just that people only need to believe you to do horrible things. That is the warning of history.

Yes, but those 8000 orders are piecemeal from any supplier that has any kind of stock, a few hundred here, a few dozen there. There's not a coordinated drive to support those manfs to increase their production.

As you say, the Dyson effort was a separate programme. Existing medical equipment manufacturers -companies that make medical equipment but not necessarily these ventilators at the moment- tried to apply to that separate scheme and they were ignored. The money went to Dyson or car makers. It's probably better to spend the money on companies that already make medical products and help them increase their capacity than it is to spend it on car makers and Dyson who'll need to re-tool their factories and re-train their staff.
I am really sorry you have bad experience with your Big Co. Understand, not every company is like that.

Also there is no need for the kind of language. It definitely isn't helping your argument so you might just as well drop it.

> Email has its own problems. Sometimes you need answers to important questions promptly. @<user> works better then, at the same time, it is less intrusive than a phone call.

I think this is a useful way of looking at it - the medium governs the expectation of response. An email basically never expects a response, an "@" in slack expects a response at some point, and a phone call is "I AM MORE IMPORTANT THAN ANYTHING YOU MIGHT BE DOING RIGHT NOW TALK TO ME". Slack etc. are obviously useful in filling the middle ground between the two extremes.

> Also, it is work time, you have to expect to be on the ready, and answer people that needs something from you, so they can get their work done, too.

I sort of disagree with this. Being expected to drop everything that you're doing and deal with whoever wants to engage with you at any point is a really bad pattern. If someone's got to the point where they're blocked on a single person responding to something, then that's a really bad smell for some process and organisational failings.

People should be able to own and manage their time. That doesn't mean they get to close themselves off from the world and ignore everyone, but it also doesn't make them an on-demand slave to their colleagues.
