> Not true. You can get speedups of 10x-100x by moving to the GPU. [...]

Ok, I take you by your word. Mind you, all the points I made were about offline rendering. I dare you to put your money where your mouth is.

Disney's Moana Set[1] it a good, publicly available example.
Show me how you get a 10× speed up using a GPU over 3Delight[2] with any commercial renderer out there. Really. I look forward to it. Note that I do not take you up on your 100× because it will satisfy me to see a 10× speedup to accept your point. By far.

Price of GPU and CPU rig need to be comparable. Electricity cost must be factored in too so if your render costs twice as much, rig plus running costs, you divide your results by that factor. And vice versa.

And as for your RIB comment earlier: don't worry -- we will add the scene parsing time to the finals; as we should.

Total time will be from render command issued to final image being available on disk.

And while this is an outdated example the scene complexity reflects what users of Houdini, even single artist types, are throwing at renderers nowadays. Or trying to.

> What is making you think that people aren't improving their rendering algos or renderers [...]

Uhhm, experience? I have been using offline renderers in production since 1994. And I see the rate of progress in commercial offline renderers drop in correlation with those people spending more effort on porting their stuff to GPUs. Sure, could be a coincidence and no causality at all. Maybe there are better explanations -- I'm all ears.

> Not true. You can't get rid of the need for denoising when using Monte Carlo path tracing techniques [...]

Says who? I would never make such a claim either way.

So before you mis-quote me again: I ever said you can get rid of the need for denoising and I never said you cannot get rid of the need for denoising for Monte Carlo path tracing. In fact I never even mentioned Monte Carlo path tracing.

Now going back to what I actually wrote: maybe re-read that. Notice the word I put in Italics so it was harder to miss?

Just for the record: you are mis-quoting me for the fourth time in this thread.

I met and talked to Damien Patton in the last year: he gave a talk at my college. I remember feeling inspired by his perspective on how anomalies of real-time public data could be used to protect and help people at their most vulnerable moments.
On my last team that would result in a JIRA ticket containing the details so approach Y was documented and the reasons behind it were recorded. Then the ticket is assigned to Person X and they go ahead with the work.
Actually, I was asking <i>you</i> to explain, or at least give your source.

I subsequently found what I believe you are working from here: https://www1.nyc.gov/site/doh/covid/covid-19-data.page
which does specify New York City (as opposed to New York State) so both the numerator and denominator refer to the same thing.

Interestingly, they appear to be using a larger denominator than your 8.5 million (NYC metro vs. NYC proper perhaps?) and get a rate of 0.175% = 175.66/100,000, eg in the "citywide total" line of https://github.com/nychealth/coronavirus-data/blob/master/by...).

But this is at least closer to your figure than I was able to get previously.

> The CCP is indeed existentially threatened by freedom and liberty because their absolute rule is predicted on its antithesis.

The easiest way to spot a propagandist is the use of "CCP", so maybe you should steer clear of that? That's why the "CCP" doesn't allow the chinese to do anything right? Chinese can't travel overseas? Attend universities overseas? Can't work overseas? If "democracy" and "personal liberty" were such a threat why are there so many chinese in american universities?

> Open your eyes, friend.

Not your friend, pal. Why are you so concerned about the "CCP", buddy? Man, all of a sudden every propagandist seems to be so concerned with the survival of the "CCP".

Neither will go to space. They are late-70s early-80s spy sats. This was a technology transfer so NASA could learn how NRO solved specific challenges they faced.

There was talk at the time about one of them being sent up in 2024, but that hasn't even been discussed seriously in the last 8 years.
Disclosure: I work for Amazon as a VP and Distinguished Engineer building our cloud infrastructure.

My professional opinion is that is a very poor strategy. Customers want to have freedom, not lock-in. When designing infrastructure services, it's good to carefully consider what abstractions are going to preserve freedom and flexibility. For example, adopting the Arm architecture, and further using the Arm developed Neoverse N1 core, provides the broadest capabilities and compatibility thanks to the investment in a common ecosystem.

The optimizations we are able to put in our silicon design, and the design of the Nitro system, let us deliver better price/performance without resorting to such customer unfriendly tactics of "lock-in".
The cost of mining doesn't set a price floor. If the price of Bitcoin falls so that the revenue of mining falls below the costs of mining, then miners will drop out until the cost of mining falls enough too.

Bitcoin is minted at a predefined global rate; the amount minted doesn't depend on the number of miners. Miners compete with each other for a share of the predefined minting action, so some dropping out does not decrease the minting rate of Bitcoin, but instead makes it more profitable for the remaining miners.
Sega of Japan didn't remember that even when it was happening.
According to my theory based on BTC history the next peak will be $225038 or a 1020% increase over the previous peak. That's kind of conservative. My last estimate for the next peak was only $8903 but it hit $20089 or 1681% increase over the previous peak. I don't own any BTC but I just did this little sheet for fun lol :) also I don't try to predict when this happens, just a very rough estimate of the next peak level based on its previous history.

You have my curiosity. What is the prediction that Stock-To-Flow made about the effect of the halving?
This should just be how websites work. I see no reason that a site should ever transmit the user's password over the wire.

When you create a password send the client a salt, hash their real password client side, and send the hash over the wire. Treat it as you would their actual password and salt/hash it again.

Then when the user wants to auth send the client the salt you have on file for them^ and repeat. Bam. A domain specific password for every site even for someone who who reuses passwords.

^ inb4 "this creates another 'step' when logging in." Users will type their username and pw before they get the salt and the client will handle the rest.

1 out of 421 NYC residents have died, based on today's numbers, and recent serological tests estimated that 20% of residents were exposed. If that's right, then the death rate would be about 1/84, or about 1.2%. But I've seen other claims that the exposure rate in NYC is higher, which would give a lower fatality rate.
Sorry, NN2 does not agree, it overwrites `length`:

function MyArray() {
this.length = 0;
}
var a = new MyArray();
alert(a[0]) // 0
...

alert( a[0] ); // "frist"
alert( a.length ); // "frist"
alert( a.pop() ); // JavaScript Error: length is not a numeric literal.
alert( a.length );

I'm not saying there will be yet another Bitcoin fork that just gets rid of the block halving "as a feature". That would be nonsense.

I'm saying that the official Bitcoin blockchain is going to get rid of the block halving, the minority fork will keep the limit "as a feature" and will be called "Bitcoin Classic" or something.
Author of originally linked post here. I welcome your constructive suggestions to make the review better. I intend it to be the best review on the internet of the best-available data on vitamin D & COVID-19 and think that it probably is currently.

The best method of increasing D levels to avoid deficiency is not the main point of the article. I have added a paragraph to note the debate on whether sun is better than supplements, but covering that debate adequately is beyond the intended scope. The urgent point is to get more data on D levels by patient vs. case severity/outcome. Such records should already exist in sufficient quantity if we can just get the right people from the right orgs (Kaiser? VA? big hospitals?) to simply aggregate the records and analyze or partner with researchers who will.
As skybrian says, Teensy has a lot to offer for audio/DSP work. The Teensy 4 generation runs like a bat out of hell compared to an Arduino or ESP32, but it's a much lighter-weight development platform than a RPi or BeagleBone.

Basically, if you want an Arduino that's roughly a thousand times faster, you want a Teensy 4.
This comment and the great edit are a positive combo. They help remind people that California doesn't have uniquely high population density.

Without reminders, that assumption tends to go unchecked. Silly (but real) example: I have heard someone say that SJ has higher population per sq mi than Manhattan.
You're completely missing the point. It's fine for amateur, non-live, non-critical work. But just because it works for you, it doesn't mean the software is stable. Hell, KDE itself (at least the kubuntu version) is not very stable so I doubt this version of ubuntu studio will be either. And suggesting to run VSTs on an unsupported OS or FL Studio under wine is likewise fine for amateur, non-live performance mode. For everything else, it's tempting fate especially when your desktop environment crashes when displaying the desktop number after switching desktops (one of many, many issues that cause kde to crash, lock up etc.).

Can you elaborate a little on what you mean by "shutdown its cities"? From my impression this was to contain the spread of the virus.

Is it really that absurd? Uber operates in over 70ish different countries, with frontline support serving as customer service, recruiting and likely driver support.

If you assume at least 50 reps per country, that alone would get you to 3500 employees. That's likely on the smaller side too, considering Uber supports places such as China and the US which would have far higher CS requirements due to a larger population. You also need to consider that this requires around the clock support, meaning you'd have also have employees working graveyard shifts or find a way to offload that to other regions.
> They had 30% of their assets seized in a money laundering sting but of course, the exchange rate remained 1:1 instead of 1:0.7

Is the exchange rate supposed to be related to the amount of assets they hold? If you go to exchange one currency for the other in either direction and that's the amount you can get, that's the exchange rate. If everybody tried to cash out all at once then they might not have enough, but neither would Bank of America. That doesn't mean the exchange rate between physical cash and Bank of America deposits isn't 1:1.

Meanwhile they presumably turn a profit, so just because they lost some of their assets, how do you even know they don't still have enough?
I have a different view. The key here is that this is a ARM based server processor, this is very different than any other proprietary CPU offers like those running mainframes.

By adding new ARMs to their fleet this will foster competition chip wise.

Overall at least for our stack (Java, NodeJS, Python, MongoDB, PostgreSQl) I think we can migrate from Intel to Arm with 1click. And thats what we're going to do.., I'm definitely trying this new chip.
That's a matter of opinion.

If you don't know jack about network programming, then of course you can retreat to Linux. But Linux is not an edge / IoT platform by any stretch of the imagination. Micro RTOS is closer, but still overkill for embedded Wi-Fi.

Specifically for Wi-Fi, LWIP is -the- stack to use for embedded TCP/IP. It is under 30K with full TCP/IP and offers everything you need. Then there is COAP or MQTT, which are miniscule compared to HTTP. mbedTLS adds another 80K for full TLS compatibility on 40MHz processors. On top of this every major wifi vendor has an SDK that fits nicely into LWIP (some even ship it), some are small (CC5000) some are larger (like the WF200), but the APIs are pretty straightforward. Now, leaving TCP/IP and 802.11 will add headaches (BLE, ZigBee, Zwave) due to additional learning curves, but only because most people in embedded networking already understand TCP/IP and 802.11 phy.

If you want to play in the embedded space, you gotta learn about it. Running back to linux might work in some cases, but not constrained IoT space.

EDIT: I had my #s reversed, LWIP is under 30K, mbedTLS is around 80K, TLS is most of that (esp. RSA stuff, I could have disabled everything I didn't need [mbed has highly granular config] based on the ciphersuite and shrunk it considerably since ECC is smaller and faster than RSA). Just checked my map file, and I was in -O0 optimization mode.

EDIT2: On second thought: if people want to complain that they need linux to do networking on the edge, please complain! I'll interview after you and demonstrate MQTT with TLS v1.3 running off an MCU with a 2032 coincell for months (eh, I'm weirdflexing a little, but still...)

If you want to have ok documentation, making everyone do it, can work. If you want to have great documentation, it's hard.

Very few people are going to be great at solving problems, great at expressing that in new code, great at maintaining existing code, great at debugging, great at testing, great at deployment, and great at documentation.

Specialization makes a lot of sense in many contexts, and writing documentation is one of them.
This article is low on substance. They quote a generic "analyst" from Susquehanna Financial Group, but never say why that company is worth listening to. The details were in "a note published Monday." Published where? Was it a company-wide memo, an email to clients, or a Post-It on the analyst's fridge?

Then the evidence for the claim: "As evidence, he pointed to data from real estate companies that showed less interest in California, New York and New Jersey as well as slowing searches for homes in larger cities."

No time frame. No numbers. No comparison to other markets Are many people shopping for new homes at the start of a recession?

But, on the topic of whether this is going to reinforce a "great migration" out of large cities, my wife phrased it best: after the pandemic scare is done, people will want to go back to "normal life." It'll be just as easy to not consider a pandemic in choosing where to live, even on the other side of a pandemic.
Thinking about this more the next level up organisation elected to represent (most of) the workers at Tesla is in fact Alameda County ....
Nobody tell him about fractional reserve banking.
So what’s the big deal? If the county doesn’t like it, arrest him and let a court rule on their authority.

As a Tesla investor, I support the relocation of Fremont production capacity out of California. If this speeds that up (even if it’s simply a public circus exercise), I have no complaints.

> how is it that none of them have possessed a mutation which (in this case) endogenously produced the signalling molecules which Katcher is proposing as treatment?

FWIW, I'm pretty skeptical of this announcement, but (assuming it's correct), it's possible that you need multiple signalling factors to achieve the age-reduction and that one single mutation might not do the trick.

Let's say that you needed four precise mutations to achieve the age reduction, then the probability of getting all of them in a single individual would be quite low.

But like I said, this announcement has a bad smell to me. In particular, the fact that they are not revealing the "rejuvenating factors" as well as the fact that they have not demonstrated age prolongation.

Finally, the complaint about the aging field being focused on cellular damage feels a little "straw-man-y" to me. I'm certainly not an expert in the field, but I imagine there are numerous researchers hunting for age-related signalling molecules.
You're neglecting the other side of things in that analysis. The more successful deadly viruses tend to eliminate their victims, so the surviving population has a higher concentration of people who are resistant or immune to it, including those who acquire immunity after being exposed to the virus.
> but it is drastically different in how it's interpreted by that other actor: computers are (designed to be) fairly rigid in interpretation (the frontier of that not being so is fascinating but in its infancy), so that there's little-to-no variance in the output.

Even if you were just being absurd and paranoid (not saying you are), I do wish more people were quick to think about the implications of jumping into proprietary hardware/software.

Perhaps it's worth reversing the question - what does he have to lose? Every stunt he's pulled in the past has been without serious consequence (defamation, stock manipulation, etc. etc.). Why should this be any different?
Why would one consider distributing it in the first place? IMHO that would require distributed transactions, which would make it hugely complex.
The two should move in at least a somewhat correlated manner, and one's a lot easier to measure accurately.
The Bay Area health officials have formed a cabal to move the entire region in concert. This has first meant the joint statement extending the lockdown to June 1st. My speculation is that this also means that the whole area moves at the same rate as the slowest county.

One Alameda County supervisor implies that perhaps he could have gotten them open by May 18th. I doubt that because the power to do so is not directly invested in the board but rather the county health officer. The health officer is acting in concert with the other counties health officers.

The leader of this group is the Santa Clara health officer, Sara Cody, who has been credited with architecting the lockdown. The officer has been very vague about opening the counties up to phase 2, saying that it will be frustratingly slow (a).

The officer points to insufficient testing and insufficient numbers of workers to contact trace (b). The officer said that they are weeks away from having enough workers to contact trace and that tests are only 20-25% towards the goal.

My issue with the tests are that they are voluntary. There is probably no way to meet that goal unless you force people to test. You can tell by the number of tests in each county. It isn't really going up very fast (c). At present rate, you are talking about several months. The issue doesn't seem to be insufficient tests. It seems to be mostly that people aren't going in to get tested since the positivity rate is actually going down.

I also think that the health officers want to work in concert since one county moving faster than the others will create pressure on the other counties to move at that rate. There is already such pressure since the rest of the state is already moving faster.

A good percentage of the Bay Area is insulated from the effects of the lockdown since many can work from home. The big tech companies have been relatively unaffected by covid-19. Government employees are still being paid. However a good percentage are not insulated by the effects of the lockdown (although it has partly opened up).

So based on the above, I expect the shit to hit the fan.
