I think a better transistor analogy than a FET is a BJT, where both the amplified quantity and control signal are electrical current.

The key difference between a clutch and torque amplifier is that, with a clutch, the output shaft power all comes from the input shaft. The torque amplifier's output shaft power mostly comes from the output drum, not the input shaft. The drums are constantly spinning, powered by some external source. https://www.youtube.com/watch?v=oNNkNc7mFJ4
IIRC there was a study done showing symptomatic and asymptomatic carriers had the same virus load. So while you simple reason is correct, there's not much else if I understand things correctly (please correct if wrong.)

I think it's a problem loop. No one wants to use Clojure because it's hard to impossible finding Clojure Devs. Also no one wants to learn it for the same reasons. The demand is less to non-existent to a point any time spent learning Clojure is unlikely to give any substantial returns.

My understanding is that GCC can cross-compile to Arduino if you target AVR. See also https://www.arduino.cc/en/Reference/UsingAVR

I haven't done it personally... but I also haven't yet poked much into Arduino either. I'm still having fun with Raspberry Pis. Arduinos... are a little more in-depth.

The core trick (and difference) of Safe Browsing is that you don't send stuff most of the time. Safe Browsing clients all download the same summary information which tells them which prefixes might have unsafe hashes. Most sites you visit will not match any unsafe prefix and so your browser doesn't call Google at all.

Pwned Passwords chooses prefixes short enough that any password you wonder about will cause a prefix to be looked up that has lots of Pwned Passwords in it. Was one of them yours? Only you know, this is k-Anonymity.

Safe Browsing chooses prefixes long enough that many sites you look at won't match anything at all. There is still arguably k-Anonymity because the total number of possible URLs is so vast, but that's not their main goal.

The Coronavirus Isn't Going Away – Interview with Harvard Epidemiologist
"that the US is not much better, at least in terms of raw numbers. We have over two million people in prison:"

There cannot be any comparison of people who are in jail for crimes, and people who are in jail simply for being a part of an ethnic group.

That the US system is not a perfect form of justice is a fair criticism, but it misses the most important point, and more importantly, the evidence for racial unfairness and not just disparity, isn't always as good as people think it is.

FYI the Chinese 'regular' judicial system is effectively completely corrupt and entirely politicized.

China very well may be using an excuse to test their ability to control their population. They may be performing whatever acts they think they need to do based on analysis of how people will perceive it, and not based on the expected actual effect it might have. Or any other number of reasons. “Because China” is not an argument that holds any scientific merit in an analysis of the severity of COVID-19.

Up to 3,000 have died from COVID so far, mostly in Hubei. Hubei has a population of ~60 million, which is ~18% of the US population. About 60,000 people died from flu-related illness last year in the US. The same proportion in Hubei would be 10,800.

So it seems it is demonstrably less harmful than flu. Why China or the World is reacting the way is it will be a great question 3-6 months from now in retrospect.

> The raw array solution doesn't work if you can't fit the entire thing in memory.

Of course it works. You don't have to literally load the whole file into memory as an array. That's not how file I/O works! Just fseek() to the desired multiple-of-20 address and read 20 bytes.

> You could try mmap'ing the file

You'd only try that if you haven't read the documentation for mmap, just like a bunch of Rust programmers did. They started on 64-bit machines and never noticed that mmap is limited to a ~256MB window on most 32-bit architectures. Certainly less than the 11GB needed for this problem!

> There's nothing over engineered about a B-Tree.

Yes there is. This guy hand-rolled 400+ lines of low-level data structure manipulation code just for the B-Tree manipulation. How much do you want to bet that he's got zero memory safety issues or other unsafety in that thing?

Would you link this to your web app? Really, a C++ library?

> That gives you answers in microseconds vs milliseconds

I don't want to call him a liar... but now I have to. At the very least, he's made fatal mistakes in his benchmarking.

There is no way that he can do random password lookups from on-disk structures in under 50 microseconds, unless he's got an Intel Optane SSD, and even then I would be highly suspicious.

He's either cached the entire data structure in memory (at which point why bother with such a complex solution), or he's used the same set of passwords over and over for testing (which will falsely show a much lower latency than you would get with real passwords).

So answer me this: How would this solution work on a typical auto-scale cluster of stateless web server VMs? Do you replicate 5-12GB to every VM every time this database changes? Or do you put one copy on a network share? Congratulations, you now have 1ms latency minimum! That fancy microsecond optimisation has just gone out the window...

To be blunt: If your password-testing is the bottleneck to the point that a 50 microsecond latency is needed, then you're running a service that gets 20,000 password resets per second. At this point you're bigger than Office 365 and G Suite... combined, and you likely have much more important scaling concerns.
Yes, at least in this application. You technically need a level shifter since the teensy has 3.3V output, but if you are running the strip at 4.5V, the output of the Teensy will just barely meet the spec. If you run the strip at a higher voltage you can run into problems.

The only market solution I can see would be an increase in gas causing people to buy smaller cars. In 2008 SUVs and trucks did poorly vs sedans and hybrids.

For example the Ford F series models sold 690.589 units in 2006 and 413.625 in 2009, but has since climbed back up to around 900,000.
Ductile iron could have been invented before 1808 if Davy had produced magnesium sooner. So this is a 'turtles all the way down' explanation.

Or is it? Imagine a directed graph of technologies where each node has outgoing links to its dependencies. Nodes may be added randomly (if their dependencies are present), but we don't consider them important until important things depend on them. In other words, there is a PageRank threshold for "inventions".

Instead of adding possible new nodes uniformly at random, we might assume their chance of discovery is inversely proportional to the sum of the PageRanks of their dependencies. Similarly, a new web page is unlikely to link to many obscure pages. (Alternatively, I think you can add nodes randomly and periodically delete low-ranking nodes.)
Do you have something that measures the PM level?
> If that's actually 1% of the 20% who show any symptoms at all, it's now 0.2%.

It's much more complicated than that and anyone stating decisive numbers is full of it. On one hand you've got the number of cases in the wild probably being higher than the confirmed cases, on the other hand there is a 1-3 week lag between people contracting the virus and death, so you can't really claim it's a low percentage until people are recovering. It will be weeks/months before the numbers start showing the true story.

Currently South Korea is the biggest source of optimism, it's only killed 0.5% of cases there, but the also only have 30/4000 that are recovered.
Mask fit is important and that's why fit tests evaluation is done for medical professionals so what you're saying has basis.

I wonder if the decreased number of pathogens makes it a different story, though. For instance if you cut down encountered viral load by 95% do you still have equal likelihood of illness?
There is absolutely a startup support industry. I am wary of using tools that seem to cater to startups only or that are interops between other startups, because I see the whole industry as brittle. Robust in aggregate, but individual services come and go daily.

I want longevity in my tooling, and I personally feel it's irresponsible to put your product into the hands of thirty companies who are all on the same growth or die cycle.
I think you are omitting the main reason why Clojure never succeeded: it's dynamically typed at the core.

It's on the wrong side of history in that respect.

I know it's trying very hard to catch up to statically typed languages now by retrofitting some type system, but it's too little, too late.

Static types are where the current state of the art is, and we're not going back. Clojure missed that train and will never catch it now.
You can - and do - use Qt's C++ objects from Python in a very native way, as though they were just ordinary Python objects. I would imagine the same would be the case when using Qt from Java or any other language that offers bindings. And since C++ with its class system is a widely adopted standard (for good or ill), there is at least some appetite for offering good bindings to object-oriented C++ libraries among the wider community, and any improvements or techniques there will generally cross-pollinate to improved bindings for Qt and vice versa.

In theory GObject is intended to be a whole parallel OO ecosystem, a better way of doing objects in C-like languages that can compete with C++, and that would ultimately give rise to a whole platform of things like Vala that interop with that platform. However that whole ecosystem just hasn't caught on; outside of Gnome, no-one is using GObject, no-one is using Vala, and so no-one else is interested in working on bindings between other OO languages and GObject (which have to solve much the same problems as bindings between those languages and C++ - GObject may be "C" but it relies heavily on macros, and to bind it in a usable way that makes it feel native in an OO language you have to do a lot more work than just exposing C functions as functions).
Sweet hack. This is real engineering.
Clojure would not gain widespread adoption even if all your points were fixed. The sad reality is that 99% of developers out there are instantly turned off by the parens and absence of while loops.
Dang - that's helpful.
Earlier today I posted here (https://news.ycombinator.com/item?id=22456642) about how throwing exceptions in C++ threads was very expensive because there is appears to be a mutex in the exception handling code. Now I can put a name to it "false sharing" - thanks!

It could be due to the criticism they got over covering up the 2003 SARS epidemic. If under responding gets you global condemnation let's try over responding instead.
The public generally has mask effectiveness confused (possibly deliberately so, to incentivize).

Masks aren't to protect you from other people.

They're to protect other people from you.

In that sense, yes, even a non-filtering surgical mask is extremely helpful. It helps keep your asymptomatic, virus-laden exhalations, coughs, and sneezes from overly contaminating your local environment.

And that, multiplied by everyone, does make a difference.

The most effective, practical response would seem to be distributing surgical masks, mandating everyone wear them in public, and restricting N95+ for health care professionals working in close proximity to infected persons.

I am of the belief that if you are trying to increase your productivity whilst mobile with small/light stuff, nothing weighs less or takes up less space in your luggage than some touch typing training software.

I can’t believe that there are people who type as much as some of us do who haven’t bothered to learn to type. It’s an essential skill.

Smart Blood Sugar Book is an incredible framework intended to help fix your glucose issues 100% normally. At the point when you balance your glucose levels, not exclusively is your danger of Diabetes or Diabetic intricacies slice deep down, yet your vitality is back, and you look and feel better step by step. The most significant thing you can do to help turn around or forestall diabetes is to begin rehearsing "glucose load adjusting." This is the procedure of effectively overseeing blood glucose at ideal levels. The explanation it works is that your body's frameworks have been overpowered for quite a long time and they need a break. In the event that everything you do is stay away from low-fat, high-carb prepared nourishments, and get a lot of solid fats with each feast or tidbit, you'll quickly lessen your danger of diabetes… and venture out switching the condition.

Yeah, the reluctance to open a client you don't use very often cannot be overstated. If you haven't played anything on a client for a year, then just opening it is likely to set off updates to the client, possibly updates to the game library, just a whole flurry of potential activity you might have to sit through.If you aren't fully committed to playing whatever is in there, it's very easy to just decide on something else.
I know a story of an ER doctor sending somebody to the hardware store for a tool. My brother also had a regular tool used during his visit to the ER. I don’t think it’s outside the realm of possibility that they simply purchased it at the hardware store. (It was a dremel with a diamond blade to remove his aircraft-grade aluminum ring from an injured finger. Let that be a warning to you about what you put on your finger.)
Unlike address bars in other OS file managers:
- Finder Go To does not provide suggestions/completions (unless there is only one single match in the current folder, it'll complete the name of that)
- Finder Go To does not respect the current directory (it always uses `~/Library`) making relative navigation tedious
- It's an entirely separate action and UX flow for absolutely no good reason

In any other OS one can open the file manager, press Ctrl+L and start typing a path, pressing tab at any point to get contextual completion suggestions.

Python and JS succeeded long before they had a static type system. Many people still use Python and JS today without type annotations. Elixir is not statically typed either and seems to be doing fine.

I like static typing and agree that it will eventually "win", but I really don't see where you're coming from here.

> I know it's trying very hard to catch up to statically typed languages now by retrofitting some type system

What makes you say that?
I’m thoroughly confused. Why isn’t details of airport screening mechanics available? IIRC with SARS thermal cameras were used to screen passengers with a fever.

> The market is an emergency force.

Do you mean emergent force?

> It isn't determined by a secret cabal of evil capitalists.

Capitalists? Socialists, communists, monarchs, mercantilists, etc also use laws to create and manipulate "the market". The US, China, Saudi Arabia, North Korea, EU, etc all create markets. Not all of them are a cabal of evil capitalists. I was talking about markets, not capitalism. Markets exist with or without capitalism. Two people could just form a market as you noted below.

> although that is debatable because it is a direct consequence of natural properties like scarcity

You can force scarcity through laws as well. Coal, fishing, diamonds, etc being examples.

> but that doesn't mean it can be simply up and changed.

It sure as hell can influence it. Which was my point.

> I bake a bunch of bread. You grow a bunch of potatoes. We are both willing to trade. That's a market.

In other words "a manmade and human manipulated entity".

Just because a "cabal of evil capitalists" doesn't say a doctor should make $100,000 doesn't mean that the "market" isn't manmade and manipulated. We could relax laws and allow a flood of doctors from around the world and I suspect doctors' wages would decline. You get the idea?

The market is no more an "emergent force" than the rules of monopoly are an emergent force. No more than cities, governments, etc are emergent forces. They are all man-made structures with levels of human manipulation.
Eh, I don't think using "American bread" as an expression for bad bread is all that horrible, just like "being on Italian time" (or Brazilian or whatever) or for people who are habitually late or "going Dutch" for splitting a bill is all that bad - even when I do know Italians and Brazilians who are always on time, and Dutch people who will pay for their table. Then again, it's 2020, so I guess I should change colloquialisms like this.
We have a winner! Microsoft is unabashedly trying to destroy on-prem IT. They are cutting out every reseller, and directly telling users things like “this feature that would make your life so much easier and make you look great in front of the boss has been disabled by your control-freak system admin”. And they have already tipped their hand that they intend to prevent admins from having any control at all on future things. You can’t even install Windows anymore without a Microsoft account (without jumping through ever-increasingly complex hoops).
But then you are saying you don't understand why people do digital nomading. While I am not sure I'd like it, I can see why people are attracted to perpetual travel.
In 1979 when I was at school in a maths class the teacher (for some reason) was talking about graphine and how it would be a game changer when invented and I said - why don't you get a bit of pencil lead and put between two bits of cellotape, rinse repeat until you got a thin layer. I was lambasted and ridiculed by the teacher.

THAT is another reason why it takes so long to invent X. People who shouldn't, quickly dismiss and idiot label anything outside the box of thinking. Still irks me, even today how I was not strong enough to stand my ground (probably been put in detention for answering back) and how I accepted that I was wrong.
R0 value is roughly 4-7. Upwards of 5% of the cases require the ICU, 15% require support breathing. Medical personnel are coming down with it frequently, and Italy is trying to bring in newly graduated nurses and retired nurses to fill the gap. This is NOT hysteria. While it isn't a death sentence for most, it is imperative to slow this thing down.

You're right, but the problem is that businesses must have recurring revenue to exist.

During the roll out phase, such as when appliances were a new thing and everyone wanted to buy one, companies could make super reliable appliances and they would still get recurring revenue because there was a ton of unmet demand.

Now everyone has a fridge, washing machine, etc. If they all lasted 30 years you would have a serious problem with keeping the supply chain alive. In the end what would probably happen is that the price would explode since now a new fridge would be more of a small run custom manufacturing job than a mass produced item.

Trouble there is that people won't pay $2000 for a fridge even if it is extremely well built and will last 30 years.

Play this out and you can see what happens. Enter the cheap competitors who make appliances that last 5 years... pretty soon the market looks exactly like it does today.

Large industrial supply chains aren't simple machines. You basically can't turn them off and then on again. A ton of the seemingly irrational nonsense in markets stems from the fact that everything has to find recurring revenue to stay "hot" or you just lose it entirely. We can't go back to the moon because we stopped going, so we lost the supply chain for the Saturn V.
If there's a limited supply and new stock isn't being added at the same rate of current stock depletion it becomes a zero-sum game... so you quite literally are.
