> You claimed that investing in sampling algorithms would reduce the need for denoising. You claimed that 3Delight's sampling algorithm is proof of that. I disagree,

Then we agree to disagree. I can back up all my claims with hard data. Can you?

3Delight's changelog gives you access to all versions of the renderer maybe back to 2006 or so. I think their path tracing core is only after 2016.

So we can download any 'sample', throw the same scene at it and calculate noise properties in the resulting image and see how they got better over time. Be my guest. I know the result and it will back up my claim. Cheers! :)

> You posted a link to 3delight's geo light sampling marketing comparison

Nice 2nd try but not biting. This is not marketing material. 3Delight doesn't employ a single marketing person and this was never published at the time when it was relevant (2017).

> I'm happy to explain more about why Monte Carlo comes with noise, in case it's not clear, or why denoisers will always be valuable in the context of Monte Carlo rendering methods...

Thank you for your kind offer, professor, no need. ;)

May I remind you that I said (analogously) that relying on denoisers for improvement is a bad idea not that denoisers are a bad idea per se?

But let's not try diverting this from you being put on the spot to prove your outlandish 10x+ speedup claim, shall we?

Or are you preparing an extra reply to my challenge?

1. GPUs are not faster than CPUs for offline rendering when you factor in costs.

1.1. They are not even faster in the general case when you just go by GFLOPS/US$. You have to look at specific cases to get a speed advantage (exactly my point: you spend R&D on making the general case work within the restrictions of the special case. Example: FP precision).

3. Time spent working around restrictions of GPUs (data transfer, memory size, precision) could be better spent at improving a CPU renderer. Proof: 3Delight.

4. GPUs are not a general alternative to CPU offline rendering because of aforementioned restrictions. That they work in specific cases means the only good reason to invest in R&D supporting them is if your target audience only ever needs to deal with those special cases. No such renderer (claiming to cater only for such audiences) exists. Thus there are no renderers out there which should focus their R&D on GPU or they are simply lying to their customers (and/or themselves).

> Do you follow Siggraph or rendering research, [...]

Yes.

> [...] and have you noticed that the rate of progress in CPU rendering algorithms has slowed?

No.

But I'm curious how you define a "CPU rendering algorithm". I'm all ears.

What if the government can't execute test & trace successfully? Right now we can only test around 0.1% of the population per day and that capability is growing linearly.[1] The lockdowns aren't restrictive enough to get R0 far below 1, so it's not clear how long it will take for new cases to drop low enough for test & trace to be feasible.

1. https://twitter.com/COVID19Tracking/status/12599631214325555...
It's not complicated because there is no conflicting guidance from the federal vs state governments. Once the federal government orders everyone to open up it will be unknown what the right answer is. States that want to continue with the lockdown will likely sue the federal government, or companies that want to open up would sue the state. The courts will weigh in and it will probably go "something something interstate commerce" and the federal government will win, forcing the states to open up.

After that it really depends upon how states respond and you could be stuck in a giant game of chicken. This is where it might get complicated and risky - mostly for people trying to abide by the law. Damned if you do, damned if you don't. But in this case, the government wont' really arrest you for not opening your car factory. But the state might arrest you for doing it.

In the case of Marijuana, it's really quite simple: everyone in California using marijuana can be arrested by the federal government. They just choose not to, at least usually.

ICE is a bit more complicated. They are trying to compel cooporation from local law enforcement, who is not responsible for enforcing immigration law. They aren't asking them to enforce it directly themselves though.
> If I pressure some friends into committing a crime

These aren't elon's friends. They're employees. There is a huge power dynamic
> Let's take this concrete example. Say there is some worker in this factory. They don't want to go to work. They don't feel safe. Now they are torn between two authorities. What happens if they do show up? What happens if they don't show up? Will they be seen as "not a teamplayer"? Will their career stall out compared to their yes-men colleges? Maybe even get fired without any cause given. Half a year later so as not to make it obvious?

Yes, I think pretty much exactly that would happen. (I'm not super up-to-date on the CARES act or other legal measures that they might be able to take, or if unemployment pays out to people who "quit" their jobs currently, so there's a small chance that those are options)

However my conclusion is that's an example of why forcibly shutting down businesses was a terrible idea in the first place and never should have been done.

But yes I totally agree, our governmental systems are not set up to handle these questions.

I must confess that when the "flatten the curve" meme started spreading around and the initial 4-5% case fatality rate and 20% hospitalization rate numbers were being given, that I actually believed in flattening the curve and thus initially supported the lockdown. I should have known at the time that the goalposts were going to be moved. In retrospect it's incredibly obvious.
Except that Bitcoin really is worth $X because someone spent $X to mine it. There is no fundamental valuation: Bitcoin is made up Internet money. It is worth whatever people are willing to pay for it. Mining is public evidence that people all over the world (well, kind of) are burning money to acquire Bitcoin. Maybe those people are cranks, but they do have skin in the game.

Webrecorder is quite good, but the necessity of using a separate program to record and to replay made this less desirable for me. I ended up making an app that integrated the two (conceptually, no technical relationship), which is rather outdated now but available here, should anyone be interested: https://github.com/CGamesPlay/chronicler
Take a look at Particle. They sell dev boards, but also have excellent documentation on how to scale (at least they used to, I'm not sure where it's gone now - have a look in the datasheet section) - obviously they want to get you into their cloud fleet management platform, but it would be a tempting solution for me. For example, you buy the dev board (fairly cheap), they also sell the SoC (cheaper when you buy in bulk) and have design guidelines for making your own boards.

The boards themselves are quite nice. It's an Arduino-like stack and you can always code in C++ if you need the STM32 capability underneath. The main stack is also open source I think.

Doesn't really cover much on the mechanical side, e.g. enclosure design. That's a whole different game and that's where people lose a lot of money - if you mess up an injection mold for example.

No it's just reality. I've had a dengue a few times. Some die. People are working to fix it. We don't shut down everything for it.

You've resigned to the collateral damage caused from the economic shut down. I have not. Maybe if you had your own business you'd have a different opinion on the matter.
It's a problem certainly.

To be fair that would also be a problem for many automated or semi-automated password managers. I have PassFF for example and it's currently suggesting the password it knows for news.ycombinator.com, I think it would guess that hacker-news.ycombinator.com should also suggest that, but if this site moved to https://hacker-news.example/ I'd need to make the connection in my head to retrieve the password.

One important thing compared to WebAuthn, which has this behaviour built into it, is that the site owner doesn't know you use PwdHash and so their testing won't discover this problem, indeed they might insist it isn't a problem at all because it isn't part of their mental model of password behaviour.

Whereas in WebAuthn it just doesn't work, so even fairly light acceptance testing would discover that the new site can't re-use old WebAuthn credentials and that's a problem.
Whenever I see things like this, it reminds me of articles about VR being dead and how its obviously not actually useful or interesting.

Bullshitters are observed to be intelligent. That is true. Confident bullshitters are assumed to be intelligent but thats because of the confidence factor. Intelligent people usually outthink themselves and "appear" doubtful when the actual case is they are considering all possible options.

There is no way you'd pay more than 15%, or even 5%, in fees.

Nah it matters because the only thing the halving changes is the unit economics of mining. Each transaction requires 700kWh of electricity (and produces 87 grams of e-waste). That bill has to be paid somehow. Currently that bill is socialized across all market participants via inflation. The block reward is converted to Tether, which is then converted to fiat, to pay the electric bill.

It's a link in the chain, which makes it fair game.
We’ve been quite pleased with AWS’ t3a offering and have saved quite a bit of money by switching. We did encounter some odd kernel panics early on, but they seem to have stopped.

We’re excited to start evaluating AWS’ ARM offerings, but until now, they would’ve been more expensive for our workload. We’ll have to see if that’s changed with Graviton2, but I suspect AMD is the sweet spot for our application; it just doesn’t seem to like ARM as much.

You shouldn't put it this way. The point is he was a dick when he didn't need to be. That's not okay. But if there was a button that said "save the planet but destroy a few (<50) lives," it wouldn't be unreasonable to hit it.
Yeah... it’s sad, there is actually a really rigorous and sound theoretical core of economics that some incredibly diligent and thoughtful people came up with between 80-150 years ago. Sadly, most of this fails to make it into modern economics courses and is utterly absent from public economic discourse.

Anyway, I would think that being unable to open your own factory while your competitors are allowed to be open when you have done nothing wrong, would be quite "unjust and unfavorable". I mean it isn't like he can conduct this type of business from home instead.

I don't think it's very useful to discuss the aggregate outcome in the USA. Fewer than 1% of US excess deaths have been in California, although 12% of Americans live here.
Billionaires are indeed citizens and no one is taking away their rights, per se. However, it is my opinion that as a class of people they should not exist (astute readers know how to flag clear opinions so they need not always be noted as such for the sake of brevity). In 2018 the median household income in the US was $63,179 (https://fred.stlouisfed.org/series/MEHOINUSA672N; numbers from other sources vary a bit but all around that point), and of course most people don’t have much for savings. $1B : $63,179 :: $15,828 : $1. My household income is quite a bit above the median and puts me in the top few percentiles, depending on how one adjusts for location. I pay a fair bit in taxes. I feel plenty incentivized to work hard; I would like to earn more and have a bit more money. At the same time, I have been incredibly fortunate in a variety of ways. It is difficult for me to see any credible policy rationale for why anyone should have 10,000 times more money than the median American household (and that’s for a modest billionaire). The extralegal advantages that come with such wealth are considerable, and worthy of pejorative usage.
If I'm interpreting this[0] right, it looks like the normal death rate is 3.51 per 421 people per year. 1/421 in NYC (is that just COVID cases or all excess deaths?) is over much less than a year, so it seems fairly serious.

But I also had a truly "weird cold" go through my workplace early this year in SFBA, so I still have to wonder what that was.

> You've resigned to the collateral damage caused from the economic shut down. I have not. Maybe if you had your own business you'd have a different opinion on the matter.

I'm not, I absolutely believe the economic shutdown could be handled much better. I believe that a certain party doesn't want to actually respond appropriately, because it would violate the narrative they push about government incompetence. I wish they valued lives more than they do, unfortunately they feel that sacrificing either those to economic plight or disease is worth the value of the idea that government is incompetent.

Either that or they are incompetent. Either way they should be removed.

> 0.2% dead and everyone loses their minds.

May I remind you of 9/11. Covid so far has been a 9/11 in NYC every week for 3 straight weeks. So yeah, declaring war seems par for the course.

Sure, fine. But let's put that aside. Like GP pointed out, the year-over-year numbers show undercounting.

So what's going on? Either hospitals aren't actually over-counting. Or they are, and COVID is still undercounted. Or the year-over-year numbers are wrong. Which do you think it is?

In all of those three world, hospital incentives are uninteresting. Why bring them up?
That is true about every factory, restaurant or any other business. Government has decided here, that it knows better (which I, FWIW, don't think is true, but it's besides the point), so people shouldn't and cannot choose for themselves how to act. So if anyone else must follow the law, how is it that Musk gets to choose? I know that the answer is "because he is famous". But should it be like that, really?

You're technically correct, but if they have access to the plaintext conversation, they can just steal the cookie that comes back.

So sure, you may have prevented the release of a reused password, but you haven't prevented anyone from impersonating your user on your site.

Depending on how they have access to your plaintext conversation, they could get your reused password from another site.

In other words, while this might make a slight difference in the stealing of reused passwords, it's not really worth the effort. There are far better solutions, like encouraging the use of a password manager.
I think we should be demanding improvements to that situation rather than demanding to be allowed to reopen unsafely.

Well, symptoms of problems tend to be more evident than their root cause, so commonality of claims is not a particularly good reason to rule out nepotism being a problem.

It would make sense that imbeciles have a harder time bullshitting. You can't continually bullshit someone that is more knowledgable on a topic.

Though it would seem bullshit ability is more closely tied to that knowledge gap between participants than anything.
