I agree that with re-opening, we will see a bump in infections, and therefore deaths. However, there is only one path out of this and that is herd immunity. We can accelerate herd immunity via vaccine, but either way its herd immunity. That means that we want as many people sick as our hospital system can handle, but not more. That means playing a game of optimization. Further, different states (New York vs. Arizona) should have different plans because their situations are vastly different (population density, current herd infection status, etc).

Further, we can't just optimize for Covid19 deaths, we have to look at the whole situation, which includes suicides due to shelter-in-place orders, child abuse and other domestic violence, malnutrition due to hunger from unemployment, negative impacts of poverty.

this will certainly be a case study for future generations.
This is nonsense. 10-30 mins of sunlight a day without sunscreen for caucasians is something on the order of 10,000 IU of Vitamin D. You can do this safely without the worry of skin cancer.

If you spent 20 seconds looking at the CA secretary of state page, you'd see what they do. Yes, they have a process for it. Yes, they've thought about it. Yes it is clunky but no solution is perfect and the system is fine.

Why not scan a government issued ID? Because that would require me to wait in line and go to a polling place, and I don't want to. I'm a busy guy. I like getting my ballot and slowly filling it out as I research the issues. I like being able to drop it in the mailbox when I'm done.

You have no actual evidence of widespread voter fraud, yet because you are worried about a potential threat which we do not see in the real world, you want my voting experience to be significantly more inconvenient. If the convenient system works fine for all its intended goals, why should we replace it with an inconvenient system? Don't we want people to vote?

Yes, you're correct, and that describes majority of "neuromorphic" papers.

By the way, which "existing ReRAM (resistive RAM) implementations of DNN accelerators" are you referring to? I have a feeling you will be disappointed once you take a closer look at those implementations.
A great talk which gets you thinking in this mindset is "Data-Oriented Design and C++" by Mike Acton https://www.youtube.com/watch?v=rX0ItVEVjHc

As an example, if you are checking a boolean flag (1 bit) on an object, and it ends up being a cache miss (and x86_64 cache line size is 64 bytes), then your computer just went through all the expense of pulling in 512 bits from RAM yet it only used 1 of them. You are achieving 0.2% of the machine's possible throughput.

I think the bigger worry isn't that they'll fuck up filing with the IRS, but that in order for them to be compliant you'll have to notify them you moved, at which point they'll be onto your clever scheme and demand you take a cost of living pay cut.

As I understand it, the benefit of PoET is that it doesn't require the massive waste of electricity that PoW does.

What I find ridiculous is that they have roughly the same security properties as a timestamping server set up by Intel. Creating a blockchain that depends entirely on one trusted party seems pointless.
I imagine by speaking out loud you also get a type of "rubber duck debugging" that makes it easier to work through problems too. Nice idea!

I would love to be able to model each artificial neuron as a separate object in code, making it trivial to group/ungroup neurons into irregularly shaped and/or overlapping groups and easily shrink/expand/alter such groups on the fly without incurring a performance penalty. Easy pruning would be just one application.

As you point out, right now, those things not practical with frameworks like PyTorch and TensorFlow if we want decent performance. Currently we have little choice but to pigeonhole all our designs explicitly into layers that operate on grid-like structures of fixed size and resort to things like masking so we can have fast multiply-sum operations.

By coincidence I was just talking about this on an unrelated thread: https://news.ycombinator.com/item?id=23118348
I understand your point but I see this as a global B2B requirement. Most products I use and have built cover North America, Europe, Middle East and now Africa. Each country or region has its quirks. If you are GDPR compliant there is a good chance you cover most other regulation. Nevertheless is an issue, especially - and rightly so - the fines are increasing and the regulation is becoming tighter. If it is not built in the extendability of a product to do so does matter and therefore the success of the template.
It's truly a shame these public tenders are invite only, I could have done a lot of googling for that money.
If Tesla goes through Chapter 11, there's no way in hell Musk will be running it afterwards.

He gets away with all his shenanigans because he's a rain maker.

Moreover, more outside time is associated with many other healthful activities. The correct model is that people who care about their health spend more time outside and therefore have higher vitamin D levels, not that higher vitamin D levels cause a dramatic effect on health. Taking vitamin D supplements if you are not deficient isn't going to make you care about your health more and is unlikely to have a significant effect on your mortality.
I'm not making any leaps, I provided a link that explained it. I have no trust in Israel to begin with due to their uncomfortable control over US politics, this was just further evidence to support that decision.
Death rate in Sweden is still way too low to have warranted a lockdown. Lockdown hurts quality of life a lot for everyone and not just the economy. It isn't worth it to lock down thousands of people for months to save a single life from a quality of life stand point. Like, you wouldn't spend a 100 years in lockdown to extend your life by a month.
Who owns the AI-driven car? Who maintains it?

Either Uber is spending a shitload of money to build, maintain, and replace their own fleet or they‘ll be leasing cars from private car owners for about what they paid human drivers in the first place.
At DEFCON, it'd be a job interview. Assuming you are looking to work for Raytheon or similar.
You couldn’t sound more clueless here. A rare screwup by IB for sure but the only reason you’re hearing about it is because the CEO is a standup guy. (Very sharp one too.) Other brokers would no doubt sweep this under the rug and/or pursue their customers for the losses.
Thank you. Can't believe the article didn't have a link to the paper.
A beautifully clear explanation.
> I fail to see how a first class framework with a LTS that was released years ago can be described with a straight face as "way too unstable".

I fail to see how you can call 2 years of support an LTS with a straight face, it's taking the piss out of the term. The LTS of the OS I'm likely to run it on is supported for 8 years. 2 years isn't even enough time to finish many projects on the same LTS it started on.

At work we've got 30 year old c/c++ code bases that still run, they'll probably run for another 20 at least, we've got 20 year old python code that still runs (for now) and we've got 20 year old c# projects that still run. That last one will never get rewritten in .net core, in part because they've pissed away the stability the framework had. It would be crazy to use tools with 2 years of support for any of those projects.

> Don't confuse "why waste money maintaining working software" linesof reasoning as a sign of respect for stability.

Why should they waste money maintaining working software when there are stable options available? What does upgrading to asp.net core get them? Why should tens of thousands of companies waste money modifying working software just because someone on the core team thought the existing API was inelegant or too hard to maintain compatibility?
Ask HN: Should email verification be mandatory during the registration process?
I am building an authentication system for my website and am trying to figure out whether I should force the user to verify their email address before they can be fully authenticated so the user can perform actions like posting, commenting, purchasing etc.

Most people online seem to suggest that email verification should be a mandatory step in the registration process, because if the user were to ever miss type their email address then they would be at risk of losing all their data when they logout or if another user were to login with the miss-typed email address.

But in practice, most websites like indie hackers, reddit, airbnb, twitch, never enforce email verification during the registration (or even purchasing) process. So how do companies like these handle situations where a user has miss-typed their email address? I'm pretty sure this has happened quite a few times on their platforms given their large user bases.

Don't people who take Vitamin D supplements _also_ care more about their health though?
You're ignoring the margin requirements.

Assuming your broker is competent (which the broker in this story is not), they won't let you buy 100,000 contracts for 1000 USD unless you can cover the potential downside, which would be of millions (possibly tens of millions) of dollars. So you can't actually leverage $1000 into going up for down $100,000; you would be tying up $X,000,000 to go up for down $100,000.

Unfortunately IB was not competent and they did not calculate the margin requirements correctly, which allowed their customers to leverage themselves improperly.
So instead of paying a bunch of people $10/hour, Uber is going to pony up front for a huge number of vehicles and the staff it takes to maintain them? Or are scads of private owners going to hand over their car to Uber to run as AI-taxis for $10/hr?
Not to mention taking credit for all the hard work the actual aerospace, mechanical and other engineers are doing under Musk. Very seldom do you hear Musk talk about how incredible the team is and how lucky he is to have them working on these problems.

He constantly praise or give credit to his teams, even full credit where it is due.

No, instead he has the gall to call himself Lead Designer this, or Chief Architect that. We all know he's not sitting down and crunching math to design rockets and cars and more.

Yes? All the bucks stop with him. He makes engineering decisions, bad or good. It doesn't matter if he doesn't have the relevant degree or did the calculation on a particular project.
Thank you! I just checked out what you're building with Aspen. This looks amazing. Love the clear language too, and the idea that users get their own "tiny piece of the cloud" – such a clear concept.

Reminds me of what Tim-Berners Lee is trying to do with Solid, but written in simple terms. Good luck!
> Except we could just as easily turn it around and point to the genocides and failures of societies with "market systems" as well.

Holodomor is a clear example that genocides belong to socialists and communists too.

You're right that we can't talk about government systems strictly in the abstract which is why we use history, and while history has different context in each instance it consistently shows us that pure socialism ends at authoritarianism, whether that's the Bolsheviks, the Maoists, or the PCV.
FB has an unlimited budget, a financial incentive, and reddit basically handed them the data. This is not even close to overkill.
Oddly enough I can't use IDE's. They simply throw way too much information on the screen, and my brain gets overloaded. So I have to sheepishly confess that I do my programming in IDLE. There, I said it.

But I think a take-home lesson is that the "right" visual environment is a function of your eyes and your brain, and might not necessarily be the most sophisticated environment.
When cars first started being released with touch screens only, I thought it was a bad idea. With tactile controls, I can adjust whatever I want without taking my eyes off the road because I know exactly what I'm touching by feel.

Now, my mother's Focus has a touchscreen infotainment system, but it also includes tactile controls for the climate control and basic stereo controls on the wheel. And everything can be controlled by voice as well. The touchscreen makes sense given the multiple functions the system has so having tactile controls for the functions you might want to change while driving makes a lot of sense.
I think if you just randomly visited Mandalay or Caesar's on vacation, you'd have the same likelihood of having your room looked in on. Every room has a notice to that effect now.
I think all the self-driving cars hysteria was just momentum from the hype of deep learning advances. I remember thinking about the idea of self driving cars within 10 years, "this seems crazy, but I guess I've been wrong before...". A few years later it seems even crazier. But I've also been wronger than that...

There were (are?) people talking about Artificial General Intelligence being just around the corner, which is a sign of people buying way too much into the hype cycle.

Strongly disagree. We are learning how to help patients survive. If I must catch it, I want to catch it as far in the future as posslbe.
I think you understand this, but just want to be clear that this is only launching next week. We're currently still on baremetal.

It'll be based on sustained queue length averages rather than any kind of load number. We can also bump it up manually.

Our estimates for some fairly severe traffic based on historic data are quite reasonable for bandwidth costs. But we're a medium sized business, so we have revenue to support that. I think individuals and very small teams can get really surprised by this.

If you're just starting out and don't need dynamic scaling and the tooling that AWS provides, I'd seriously look into colo so that you can buy bandwidth using 95th percentile billing. We use a combination of servers that we own in data centers using 95th billing and AWS. Depends on use case and we have gotten very good at financially modeling future costs for a given config.
One thing that might help a bit is to make the profiles you've already done public (well a curated list of popular sites maybe so you don't leak information). Have a list on the home page, so I can see what a report looks like, even if it's not the page I want.

Or maybe the page I want will already be there!

My wife is a SAHM. Usually during summer vacation she does just fine handling the kids without their being offloaded to professionals.

The current situation is a lot tougher, though, since a lot of the things she'd normally do with the kids during the day are denied right now: the zoo is closed, museums are closed, playgrounds and parks are closed, gymnasiums are closed, no play dates with friends, no visits from family, etc.

I think it's unfair to try to draw your conclusion from the present situation.

I've recently been thinking about the way we note take in general, reflecting on my experiences with Notion, OneNote and many more.

$TERM Is Terminally Broken
“ The plan was for the Javits Center to take patients from overwhelmed hospitals in the city. But in practice it wasn't that easy. Some hospitals complained that the intake process was too complicated. And they sent few patients to Javits — even as they resorted to treating patients in the hallways”

What does it mean for an intake process to be complicated? Isn’t it straight forward like loading the patient + printouts of medical records into an ambulance, driving to the new place, and then transferring them into a bed?
> It's not that hard to look this stuff up

Aside from the fact that most health studies papers are retracted within 10 years, or found to be the opposite of what was claimed.

Which is less annoying than people like you who fetishize anything published. I suggest you learn what "peer review" actually means before telling people to run off and read about false health claims.
Nope, you definitely do not. It would definitely get the attention of some vulnerability development types! But there are also more professional - if occasionally less fun - ways to go about that.

If memory serves, the "open" network has seen novel attacks used in years past. But not many.
Control when held, escape when tapped. First thing I set up on a new machine.
Swedens approach is working. Current number of deaths is still too low to warrant harsher measures and deaths per day has been going down for weeks now.

300 deaths per million isn't that many really. That means 3000 persons per death, significantly hurting 3000 persons quality of life for several months just to save a single life which 90% of the time is above 70 and therefore doesn't have many years left to live isn't worth it. If locking down 3000 persons for 3 months makes everyone who died live 10 years longer then we say that 75 years of lockdown is worth 1 year of life. So a person would happily spend almost their entire life (75 years) in lockdown just to live one year longer. I don't believe that at all, nobody would make that choice. Just quitting smoking would save way more with way less effort.

And that example was with 10 years per death, most who are dying were already on their deaths door with less time left than that. Also we assumed everyone would survive if we did lock down, which is very unlikely.
