Awesome! I'll have to share these with some friends who have kiddos at home right now.

I've been doing something similar at http://colorthisthing.com. Skipped today for a day off, but I've been posting one everyday since I started. Fun way to keep my brain occupied since most of my other artistic outlets are shut down right now.
Dollar is weakening? Against what currency, I've been watching a jump to US currency.
Isn't it more that real time kernels are necessary period? The number crunching itself can't be that problematic...I just upgraded an old Anilam mill controller that ran 3 axes. It was running on a 386.

The new encoders on the servos are way better, but the replacement modern hardware is also way better.

I think in both cases (especially the upgrade), the event handlers and drivers are all done in separate, dedicated hardware
I'm not sure "opportunity cost" is the correct term for what the OP wanted to say, since it usually refers to the (theoretical) loss incurred by choosing one alternative over another. The point is simply that a consumer's ability to pay is not necessarily a reflection of their need of the product. That's not an argument to blithely decouple pricing from supply and demand, but it's a recognition of a problem that a market-based society needs to deal with under extraordinary conditions.
also, when it says for the victims of hiroshima, it doesnt mean for them to listen to. its a piece for their experience to speak to the world. its an honorary for the victims, directed at those who werent. its open to interpretation though

Indeed, a bit of confusion about "Arduino" is that it has come to mean two things. One is the original Arduino board and its "branded" successors. The other is the development stack. In the latter case, it's GCC with some libraries and a beginner friendly editor. It's bare-iron programming.

Thinking about dealing with an encoder, let's say it has 8k counts per revolution, and the motor can do 10 revolutions per second, which is pretty fast for a stepping motor. Then the encoder steps are coming in at an 80 kHz rate, but an 180 MHz MCU can execute a couple thousand instructions in that time period, so it's not even breathing hard.
What is their fully burdened cost of fuel today? It seems like it would still be tremendously expensive.
My partner works for an Australian university, she had this to say when I shared this article with her:

"From my understanding Bachelor degrees are much more regulated (in Australia anyway). Private Colleges can offer Grad Cert and Grad Dip and Master degrees but not Bachelor degrees, which make me think the government has highly regulated Bachelor degrees.
I think that there must be a certain percentage of face to face, practical subjects, mentoring and industry placements, but I imagine in the current environment that this will be all up for discussion."
Wouldn't you be within the law if you simply sold the rolls at your own cost, or even your cost plus 10%, rather than trying to turn a large profit from them?

No, those compilers would likely reject it, if I had activated c17 mode. But I did not -- so it worked.

This is a real power of C and C++ -- each file gets its own mode. That K&R library you made in ancient time? C++98 classes? All still works and links to the modern stuff. You can be sure that whatever code you wrote today would still be usable, possibly with minor modifications, 20 years later. Sure, the compiler names and build systems will change, but the code would work.
I've played with the Pixelblaze and it's pretty sweet. As far as going from nothing to being able to control a string of LED lights with a series of pre-programmed effects, it is really easy.

That said, I ended up abandoning the project I was going to use them for: permanently installed Christmas lights that doubled as just normal outside lighting when it wasn't a holiday. I ended up, just this weekend in fact, installing just a white LED strip light for that. Which I just did on a whim yesterday afternoon, after someone was prowling up the street looking for open cars that morning.
In that case perhaps the solution involves no lending companies.
FWIF he's pledged to donate 99% of his wealth upon death. Given that he's 90 years old, I imagine his primary goal with this capital is preservation, not achieving returns in excess of the market.
That will change when they have 20 times as many patients and the alternative is to let people die alone in the hallways with no help at all.

We now use Teams at work for video conferencing all the time. Before the emergency we hardly ever did.
It is relevant and it does support my original argument since I agreed with Google cancelling the April fools jokes for another time, as it would be bad timing due to the seriousness of the Covid-19 pandemic regardless if the jokes are on the front page, Gmail, Maps or wherever on Google.

In relation to that it's bad enough that there is false and misleading medical content and advice floating around the internet and on social media which is very dangerous for non-medical experts. Thus, such resources should be used to promote medical content from verified sources for lots of people seeking clarity of the outbreak, since Google and others already have the reach to do this and they are indeed doing this.

My point is there's a time and place for April fools jokes. This April probably isn't the wisest of times when being in a middle of a pandemic. Especially if you're running a large social network or search engine with hundreds of millions of daily users potentially consuming and sharing medical advice or content which could be misleading or unverified.
Evey time I see an article critical of Chines government in SCMP I feel a shock until I remember it's a Hong Kong paper.
But then I feel a little confused over Hong Kong's semi autonomous status.
Yes yes yes! I was literally thinking to implement this myself, but didn't have time. It's a shame doesn't appear to be open source though - I might still end up creating one.
And yet I understand this is what is happening in Italy where the suspected cause of death is Covid19. If we don’t make it realistic to expect this (during a pandemic), then how can we trust the numbers?
Another case in which the numbers are oddly (one might say "suspiciously") different are the UK's number of critical patients (163) compared to their known number (19522), which is very low at 0.8% compared to France's 11.5%. That's a massive difference in the number of seriously critical patients, given that the UK has a sufficiently large sample size now.
A huge factor here is time. 3 weeks ago I saw a bunch of people saying "Look, South Korea tested a lot of people, finding the majority of the mild cases, and thus only has a death rate of 0.5%". Since then, however, deaths/cases in SK has risen to 1.59%, and increasing daily. They don't have many new cases, what's happening is the cases from 3-4 weeks ago are dying.

Germany has tested a lot and found a lot of cases earlier in the disease progression. I'm sure their death rate will rise like S.K.'s did. Not all the way to the 8% - 10% we see in Spain and Italy, but I'd guess up to 2%.
"64-bit encryption" is charmingly quaint.
In the meantime COVID19CZ created an open source version - https://news.ycombinator.com/item?id=22724130, crowdfunded the first batch of 100 ventilators, and they start producing them in the first week of April
Thank you for the recommendations! I'll check those books out.
Yes, I expected that it would make a nonsense argument based on the description of the person linking to it, and that's what happened.

Look, it's them that made the argument. I even quoted the relevant parts. They're clearly arguing that Ender is aggressive and bad because he's violent in response to violence against him. Self defense apparently doesn't count.

If they want to make an argument that makes sense instead, they should do that.
Also the article assumes 100% infected. If it is only 50%, then death rate is 0.5%. Although the graph does show there are more deaths expected.

We can actually expect the mortality rate is a lot lower than 1% if the hospitals are not overloaded.

Counterpoint as at March 23rd: “Among 3,711 Diamond Princess passengers and crew, 712 (19.2%) had positive test results for SARS-CoV-2 (Figure 1). Of these, 331 (46.5%) were asymptomatic at the time of testing. Among 381 symptomatic patients, 37 (9.7%) required intensive care, and nine (1.3%) died (8). As of March 13, among 428 U.S. passengers and crew, 107 (25.0%) had positive test results for COVID-19; 11 U.S. passengers remain hospitalized in Japan (median age = 75 years), including seven in serious condition (median age = 76 years).” - https://www.cdc.gov/mmwr/volumes/69/wr/mm6912e3.htm

So mortality rate is 1.3% and expected to rise, but that is probably skewed by age cohorts, so rate in countries with more young people than a cruise ship might be expected to be lower.
It's interesting where he's pointing out the real-time debugging support in the chosen board.

One "weird" thing that popped out about that for me, is where he said it's not possible to do that with the "other platforms" he's shown.

Does anyone know if the debugging style he's mentioning is different from attaching a segger to the debug port on the Due? Asking because I've done exactly that before, when working through bugs in the g2core (multi-axis CNC controller) firmware.

To me, being fairly newbie level with it, it sounds like the same kind of thing. Perhaps the author just isn't aware some Arduino's do have a debugging port + commonly available tooling to use it?
Satellite navigation is a key strategic asset, as is any system that carries national and trans-national communications. Imagine being able to interfere with a navy's navigation, maybe not enough to stop them from getting somewhere but definitely enough to slow them down. Or imagine being able to change the position of a communications satellite, a device that is basically just dumb microwave relay---and microwave, I'll remind you, is highly directional. Or what about getting access to the ground station's network traffic? I'll bet that even when it's encrypted, there's still useful signals intelligence to be gleaned, and when it isn't encrypted (or encrypted badly), boy howdy.

Satellites and their attendant infrastructure cost billions of dollars to deploy and maintain. They are incredibly valuable targets, making it worth an attacker's while to penetrate them. This is way beyond simple vandalism or ransomware.
NextDNS is a commercial solution, there will be more limits to the free plan when it will be out of beta. DNSCloak is just a tool that let you choose different DNS resolvers, even your very own.

In the short term it might look bad. But in the long term it would encourage other companies to enter the market and existing players to increase their capacity.
This is phenomenal. Great work!
At the moment it's reputational enforcement: if enough people badmouth them on Hacker News, the money will flow to competitors. (There are other ways to enforce norms, but they have their own problems.)
A lot of it has to do with luck. It is like trying to figure out the secret of a person that won the lotto.

Yeah, well I'd prefer to see copyright abolished. It's totalitarian to try to control what data people can share and store on their devices. But as a first step, we can start finding alternative methods of funding the creation of information. I'm not a supporter of Soviet-style bureaucratic command-and-control socialism, everything should be voluntary.

I suppose you could complain that funding creators by taxation (or government debt, more likely these days) is involuntary. True, but I just see it as a way of paying for civilization. In total, the cost may be similar to what people are currently paying in copyright licenses, but with the benefit that all works would now be available to all.
> no matter how healthy the production and trade were before being stopped

The economy had at least two noticeable and possibly systemic issues before Covid-19. The several yield curve inversions combined with funding problems in the repo market. We certainly hope for a V-shaped recovery but there is no telling what kind of issues have been attributed to the virus that may still be there when this passes.
Another business that may not survive the pandemic. Poor way to spend their limited resources.
> How do you stop the billing otherwise?

With prioritisation, so the non-steady state services are stopped/killed with plenty of time to leave the needed foundations still running. :)
We now use Teams video chat at work. The results have been mixed. When the number of meeting participants is low (<5) the video seems to work well. Anything above that we start seeing random disconnects. We've had better experiences with Zoom for larger meetings (~25).

If anybody at AWS is reading this: congratulations! Thank you! Keeping infrastructure running is hard in the best of times, and these times definitely are not the best.
I think there would be a different answer depending on who you ask, but some of the biggest downsides as of now:

1. Lack of DANE/TLSA support in browsers

2. Lack of SSL since the CAs aren't issuing for Handshake Names. This is independently solved by #1.
Yes, you quoted a section that describes how the characters in the book view (and struggle with) the fact that the main character kills violently and how that is justified by the different circumstances.
And then somehow claimed that the author describing that means the author thinks circumstances don't ever matter.
This isn't a student debate on epistemology, but if it were I'd begin by asking how you prep for the future without knowledge of the present situation.

As it isn't a student debate on epistemology I think we can leave this conversation here.
The market system has, so far, benefited hoarders to the detriment of health care providers that need it more. Under normal circumstances, the market system would be just fine. In a crisis, something else is needed on top of normal market forces, which may still play a part for whatever resources are left after they reach those that truly need it.

As for who is responsible for that decision, it's a role the government generally fills. Can it be a bottleneck? Yes. But there are extreme bottlenecks now with hospitals already out of, or about to run out of, PPE and ventilators. Might there be mistakes? Sure, but again there are mistakes right now too, with market forces favoring those who can pay, have inside connections, etc., instead of those who need the resources. In short, the detriments you cite are a reality of any system, while their presence during a crisis can be mitigated at least a little, and help critical need be filled at least a little bit easier.

Don't let the desire for a "perfect" allocation system blind you to one that is merely "better" than what we currently have now with panic buying, hoarding, price gouging, etc.
That fact is because the bachelor degree no longer has any particular value. It’s the new GED. It’s required for jobs that do not need that level of education. It rarely is enough to qualify for a job that needs a university education.
Oddly specific use-case. This only tracks the location of folks with Saudi sim-cards using roaming in the US. Even then, only down to the tower. Now that the guardian has blown the lid off, I expect this is largely worthless for them now.
Well, you can run the simulation and such without it, but for doing any real work, yes they are necessary. That was kind of my point though: you could in theory put one of those kernels on an RPi or something (barring compatibility issues with the chipset), but you'd probably still be lacking the proper IO hardware, etc.

> My employer would have a lot more runway if our execs were making the same as the rest of us.

He was making the same as the rest of his staff so where is his runway? First serious crisis in 5 years since that article and he's scrounging for $70K.
This article is extremely light on details.

All that matters at this point is effective anti-virals, and aggressive use of them before the virus or immune response damage the patient's lungs to the point that they need ventilation/ecmo.

We can't afford to wait 18 months for a vaccine.
How coronavirus could affect software industry?
Some say after covid-19 more companies will realize their job can be done remotely which will lead to increase the demand for more software engineers. While others say recession is coming and most companies will reduce their IT budget.
Do you know how covid19 will affect the software industry?
Right, for example what if there is a second strain going around that is obscured by the large inconsistencies in testing and reporting?
Are your VMs failing on deployment or after they are deployed?

If it’s after deployment that would be concerning
You seem to have read that statement wrong. I never said the fastest directory crawler on Planet earth. I said "the fastest directory crawler for NodeJS" restricting that claim because I am aware of the implications and how far-fetched it would sound.

As for the "1m files in < 1s", yes I benchmarked that privately. That is not a false statement and to back that up, I will be uploading a gif showing the time (once the cli for fdir is done).

> The same code can perform better or worse depending on node/v8 versions.

I provided benchmarks for 2 node versions. The benchmark was fair for all libraries. It was run in the same way on the same machine for the same number of times on the same directory. So relatively the results should be fair. They were all also used barebones without parameters. Of course each library has its own approach. I cannot be held accountable for that.

> what filesystem was used? was it encrypted? was it in a RAID array? There is some missing context here as well.

You seem to have missed the whole point. You seem knowledgeable enough so let me say it in simple words. All node libraries that crawl directories for files use the `fs` module internally. Now, fs uses LibUV underneath. That is true for all libraries. There's no exception (to my knowledge). Now since the underlying i/o and the v8 engine are exactly the same, the only thing that makes the difference (and very slight at that) is the logic. Fdir wins only against other node libraries through that logic not because of some new i/o approach.

The figure 1m files in < 1s is just to give an idea of speed not to show that you'll be getting the same exact number.

I am aware of how fragile this claim is but until there comes a faster libraries I have the right to hold it. :)
1) If you're AT the budget amount then everything must be deleted to avoid going over.

2) If it's a soft budget then it's no different than the alarms you already have.

3) If you want to stop it before it hits the budget, then you're asking for a forecasted model with a non-deterministic point in time where things will be shutdown.

This just leads to neverending complexity and AWS doesn't want this liability. That's why they provide billing alarms and APIs so you can control what you spend.
No way. I'm a resident of a rural state.

We’ve known that pandemics were going to get more likely as international travel got faster and cheaper, and population density rose and absolute population numbers rose. These factors have been part of the horror stories that epidemiologists tell each other late at night when the lights are out:

“so it was a normal year, and airlines reduced the cost of India to USA flights by 20%,”

horrified gasps (the audience knows where this story is going)

Pandemic might have seemed improbable to you as a layperson, but the medical community has been bracing for this for decades. The less seriously you take it, the less seriously your politicians take it and the less seriously pandemic preparation gets funded.

I agree other ecosystems have similar debugging capabilities; I think the main driver for hardware selection was deterministic timing and ability to keep up.

See my comment further down beginning "Starting about 7:09 he talked about why the Arduino wasn't a good fit..."
Is there any empirical evidence for having patients on their stomach instead of their back on ventilators? That seems absurdly easy to test.
I was an arrogantly agnostic and intellectual young adult when I read it. It had similar results.

I think the appendices may have been most important to me, ultimately. Some more than others of course.

Every now and then I return to it and the painfully sixties parts get even more painfully so - I suppose I shouldn’t expect an subtle treatment of women from a couple of guys who were working at Playboy when putting it together, but it’s still grating, and makes it harder and harder to recommend to the next generation.

Also it inoculated me against Ayn Rand with its parody of her extended paeans to the joys of being fucked in every possible way by rich assholes who value money over morals, and after seeing the damage done to society and people by libertarianism, I cannot thank Wilson and Shea enough for that.
I can also recommend WGU. I only wish I’d found them sooner. I took a break from school 14 years ago because I ran out of money, and had no problems finding a job without finishing my degree. Then life got in the way and I never found a good reason to go back to school.

Then after a while I started contemplating going to grad school, more of a nice to have for personal development reasons.

But I couldn’t without a completed undergrad. So a little over 2 years ago I enrolled in WGU and now I have 3 classes to go.

Gcc already (gcc-8) reports possible undefined behavior for loops and these are mostly out-of-bounds in my code. I like that a lot, actually, it save a ton of time.
Not for Azure as a whole, no, but that sounds entirely plausible for specific services like Teams.
> it wasnt exactly written for easy listening, it represents the instantaneous annihilation of life on the largest scale the world has ever seen.

As is well known (or should be), Penderecki wrote the piece initially as purely abstract music, a study in sound. The title referencing Hiroshima was only applied to the piece later.
