> but culling doesn’t really work for complex on-screen geometry like foliage, hair, volumetics, crowds, etc, and games are pushing in those directions.

Just because something doesn't work in all situations doesn't mean it doesn't work in general. Games putting polygonal leaves and crowds full of furry creatures would be a waste, it isn't going to happen without level of detail.

It is actually cheaper for film quality assets, but the camera visibility rays aren't where most of the time is spent. Still, things like REYES / renderman architecture decouples all the sampling required for motion blur and defocus so that the visibility samples don't have to be shaded.

> The other appeal with ray tracing is being able to consolidate all the various tricks and algorithms into a single path tracing framework.

My reply was about ray tracing not actually being faster than rasterization for first hit visibility in practice. I didn't say anything about ray tracing in general here.

It's not fruitless to point out that we shouldn't jump to conclusions based on only knowing one side of a story.

As to "what else should he have done", assuming that he really was trying to help with something totally outside his professional expertise and personal experience, I think a good start would have been understanding the topic on more than a superficial level before charging in to say they so blinded by their biases that they were doing it all wrong. That's not the way to get anything done anywhere. Taking a few classes in relevant topics would have been a great start. He also should have aggressively depoliticized his document.

And then if he were really serious about making change in an organization that size on such a big topic, he should have spent a lot of time getting to know the people involved, socializing his ideas, and learning how to pitch them in a way they could be heard. That's how most things get done in large companies when one isn't a high-level executive.

I'm glad we both now agree that he published it internally. Thanks.

If you honestly can't figure out how using a term of political attack is seen as an attack, I'm not sure I can help you with that one. If you're not a native speaker, I recommend reading up on the history of the term.

And lastly, what I'm saying is not "guilt by association". To the extent that there are reasonable doubts about his motivation for writing the memo, we have to look to other behavior to see what theory it fits best with. That his first choice was to get cozy with antifeminists is a piece of evidence. So is his choice of a right wing lawyer. So is his lawsuit that conservative white men were being discriminated against at Google.

There's also the lack of him doing anything particularly indicative in the other direction. If his goal was really to improve things for women, as has been claimed, he's had years to take action. Or just to write new pieces.

I'm open to new data turning up, but to me the pretty obvious conclusion is that he didn't somehow accidentally write something very similar to a lump of right-wing concern trolling. He's obviously smart, so it would be weird to think somebody normally as precise as a Google engineer was just suddenly very sloppy. Instead I assume he wrote what he meant to write and upset the people he wanted to upset. Apparently he thought he'd somehow win the day, but that's not the first time an engineer would have arrogantly leapt in to something thinking they had solved it all. Or, for that matter, somebody with a physics degree: https://xkcd.com/793/

Well, you don't know that. There are states and countries that have not gone to "shelter-in-place" extremes and have been outperforming California.

New York is special in America. It's very dense, and every time you get on a subway train, which most of the city does every working day, you're sharing a cramped space with hundreds of random individuals. It's not hard to see why they've been hit harder than anywhere in the US.

To pretend the only possible difference is a binary distinction between lockdown or not is reductionist ad absurdum.

I wonder what the cost would be to build out a secondary backup site on a different continent.
This is still true. Your second sentence is correct, but the rest is not. Most research does come from within the system. Unconventional research does not and cannot come from within the system.

Funding comes from calls from proposals which are within existing, established research fields. Funding outside of a current research field is nearly impossible to find. If your research isn't in an established field, there isn't an NSF/DARPA/etc. call to respond to, and there is no program officer who has any interest in your work.

Similar through the whole research pipeline. New areas of research don't have established venues where you can publish, people to cite your papers, or a community to write academic reference letters for you. People who work in new fields are usually doing so as nights and weekends projects, or are independently wealthy.

And although the vast majority of independent researchers are crackpots, a few are credible and do occasionally make major breakthroughs. Importantly, the majority of breakthroughs outside of established fields are made be people unsupported by NSF, and without good venues to publish (although quite often, those individuals are academics working in their spare time, so half within the system and half outside).
I don't know if you've ever considered a position in pharma or biotech, but clinical research has a career like this called Clinical Trial Associate, and their entire job is to organize information, prepare instructions and documents for the research sites, organize and run the eTMF aka "Trial Master File" and other documentation tasks. Our CTAs start at 95k and make up to 125 for senior level. From there onwards you have a good career path of Clinical Trial Manager and leadership- might want to check into it.
We only use NiFi on the edge of our data lake. It's very good at bulk loading, pulling log files/sensor data from hundreds of systems into our systems.

The problem with that analysis is that it assumes past performance has something fundamental to do with future performance - it takes a lot more investment to move the price of BTC from $10k to $100k than it did to move it from $0.10 to $1.

Apple stock has increased 100x in the past 15 years, but that doesn't mean it will increase 100x in the next 15 years (which would put its market cap at approximately 5x US GDP).
That's because you need time to adapt. In half a year with proper processes things would fly. This was sudden disruption of everythong on the planet so give humans some slack.

Just took a radars course and we definitely spent a whole section on just atmospheric effects / defraction.

> I can back up all my claims with hard data.

That's where I think you're already off the rails, I don't think this particular point can be proven with hard data, it's about goals. Denoising helps whenever there's noise. 3Delight produces noise with low sample numbers, just like all other renderers. A denoiser will make that faster and enable quicker preview turnarounds.

Your argument is that 3Delight's algorithm makes final frame rendering faster, which I'm not arguing with. If it takes longer than 5 seconds to get to final frame, it doesn't matter whether it's faster than others, denoising will provide the same benefit.

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

I was really referring to just rendering algorithms in general. There were a lot of papers on how to speed up rendering algorithms in the 80s and 90s, and the speedups were large. A lot fewer in the 2000s and 2010s, and the speedups are no longer multiples, but more often measured in percents. Based on your claims, I'd think you'd have noticed this trend. It's directly related to the rate of progress of features and speed that commercial renderers are releasing.

Feel free to provide sources on flops/$ for fp32. (BTW, talking flops/$ ignores RTX.) First Google result disagrees with you https://aiimpacts.org/current-flops-prices/#Graphics_process...

Saying that GPUs aren't a general alternative is true but ignoring the trend. They used to be much less of an alternative. They are currently a fast alternative for some workflows, especially preview. They will in the future become more and more of a general alternative.

miners group transactions into block (ie mine). whoever manages to form a block (you need to solve a computationally expensive problem that has the transactions you want to include as inputs) get a reward. up until today the reward was 12.5 bitcoins. Starting today it's half of that 6.25.

speculations about what this means and where BTC is going follow from this.

50% of TDEE permanently? Goodbye muscle tissue, hello injury, hello terrible moods. Life will not feel like it's worth living. (You must be joking?)

If not joking: Have you tried this? I lost 36% of my bodyweight by eating under TDEE. It requires huge amounts of effort to even hit 25% under TDEE consistently. A lot of that effort involves annoying your friends and family by not eating the way they do. We're social animals. It's hard. Plus when you get to a certain weight you will realize you have to regain muscle tissue, and the question of a bulk/cut cycle will come to mind. Goodbye 50% under TDEE.

I also had a very sudden onset of a severe body ache around Feb 2020. I started having some pre-flu symptoms. And after one day, I started having a very severe body ace and it came so suddenly. I have never felt sudden onset of body ache from a flu/cold before.

I took a nap for 2 hrs or so and it fortunately went away almost immediately.

I know a family friend who were scheduled to go on a trip in early Feb 2020 but cancelled it because both had very severe flu symptom. This was an important trip (a road trip of few hrs to visit family) that had been scheduled weeks ago.

One of them to told me he had a meeting with a visitor from China who had mask on. And they think they might have had Covid-19 but no way to know until they get the antibody test.

Somewhat ironically, the only people who still make discourse concerning value theory are heterodox economists and philosophers who disagree with marginalist value theory, and mainstream economists tend to have very little engagement with them, either in agreement or disagreement. The debate rages on (though much more quietly) with strong normative implications. Paul Samuelson himself was arguing the point in the 70s and 80s. The real shame is that people think these issues are at all settled in economics simply because many economists believe them, or don't concern themselves with them because of their abstractness.

As I recall, Bitcoin was designed for resilience to government pressure. But that's never been tested, in any substantive way.

I'm not aware of any reason why the Bitcoin network couldn't switch to VPN-level overlay networks. Using Tor would be somewhat problematic, given the limited bandwidth. But I'm pretty sure that it'd be doable. Other options include Orchid and Loki.

Mining could be an interesting issue. Government pressure could render large-scale mining operations unworkable. But as I understand it, the Bitcoin network could function just as well with far^N less mining capacity. Difficulty would just decrease with less mining competition. And that would mitigate the key negative impact of electricity usage.
> You claimed that investing in sampling algorithms would reduce the need for denoising. You claimed that 3Delight's sampling algorithm is proof of that.

One thing I can share is that 3Delight has a found a way to do weighted filtering of pixel samples w/o introducing correlation. They do not publish any papers though.

Many other vendors of renderers have this issue and the noise this correlation produces is hard to remove.

But I'm sure you understand all that since you were offering to lecture me on Monte Carlo methods below. ;)

Because of this e.g. Intel Open Image Denoise needs uncorrelated pixels samples to work at all.

And the crazy thing resulting from this is that Intel ask you to turn off this sort of pixel filtering in your renderer. Which makes the image more noisy.

Aka: you are adding noise to be able to then denoise. More irony ... this time lost on advocates of denoising, I guess.

Quote from the IOID docs: "Weighted pixel sampling (sometimes called splatting) introduces correlation between neighboring pixels, which causes the denoising to fail (the noise will not be filtered), thus it is not supported."[1]

This is actually misinformation (or maybe trending fake news?). What they should have written is "We believe that weighted pixel sampling (sometimes called splatting) introduces correlation between neighboring pixels [in all renderers we know of] [...]"

To quote a 3Delight developer on this text: "That text from Intel, apparently the same as for RenderMan, is pure, unadulterated, pseudo-science. [...]
3Delight will work with [the] Intel denoiser [...]"[2]

Proof: you can feed a pixel filtered image from 3Delight into IOID and it will work as the samples are not correlated[3].

2. Update game state for every player every 100ms. Why didn't it work? Player 1 and player 2 are running different instances of the class that is supposed to update game state, and I can't share the instance between the two
