Using GPUs for offline rendering to gain speed is a dangerous fallacy. Dangerous because the GPU has many restrictions which developers have to invest time in working around.

I feel in recent years makers of offline renderers have spent more time dealing with these restrictions to get their renderers to work well with GPUs than actually improving their renderers. I.e. reduce level of noise, better algorithms for hair, volumes, etc.

The renderers produce way too much noise (or have prohibitive render times w/o except for big studios).

Solution? Denoising! Which is (mostly) using GPU-powered ML!

The irony of this seems lost on many freelancers who buy expensive GPU rigs to be able to deliver their jobs on the likes of OTOY or Redshift.

For this money you can buy a vastly superior CPU rig. If only your renderer could use it! Most people compare apples to oranges here. When I hear people rave about GPU offline renderers, I usually ask them:

- Have you made time to first pixel part of your comparison (complex scenes can take dozens of minutes before they start rendering on GPU renderers).

- Are you comparing images as they come out of renderer A before denoising to images of renderer B before denoising? Because anyone can pipe their shit through Intel Open Image Denoise after the fact. It's free even.

- Have you actually used a machine that has more than eight cores personally in production? If all your money goes into buying expensive graphics cards your CPU is usually shite.

A notable exception is 3Delight which doesn't even ship a denoiser. On simple scenes the renderer can't beat the GPUs but on anything a bit more complex -- the stuff you deal with in actual production -- it smokes the competition CPU & GPU alike.

Not least in the amount of noise it produces using comparable sampling settings.
Without using any GPU compute.

When this GPU craze took over other vendors who's renderers were traditionally CPU bound too, in the last 5-6 years, 3Delight's developers have spent all their time finessing the performance and output quality w/o relying on GPUs. It shows.

The APIs are intelligently laid out such that hardware accelerated raytracing can be used on popular APIs regardless of GPU vendor, if the vendor has made their drivers correctly.

The sketch app would also start within microseconds of me pressing the pen button (ignoring BTLE connection latency).

The Whiteboard app first takes seconds to start, then it stays some additional seconds showing an empty screen until it decides to start the login process, then it needs a couple more seconds until you can actually sketch down your note. By which time I have already forgotten about whatever I was going to write down.

Setting the pen button to launch OneNote is now literally faster than Whiteboard and that's just ridiculous considering the idea of not putting OneNote in there in the first place was to have something quick & snappy to take quick notes.

The "just press the pen button and jot your ideas now" idea was broken the day they shipped Whiteboard. The "new" Microsoft is just as ridiculous as Google. They kill their own usecases as fast as they create them.

That's a typical FUD campaign. Reality is irrelevant to the narrative, and discussion is railroaded into drawing conclusions while accepting the premise without questions.

It's Iraq's WMDs all over again but even weirder because it is a topic that has very little practical value. This is purely political.

Now, if the US can really pinpoint mobile phone calls within a building, in the middle of China, surely that should be the scoop here.

Ah righto, the reverb pedal I'm most familiar with turns out to not be just reverb - EQD Afterneath does a whole bunch of funky stuff. Plain reverb though, yeah. I was approaching this more from the angle of training a neural network, where the input and output waves have to be correlated over a great span of time/ samples.

I didn't like Unity at first either, until I got to use macOS a bit more. Got used to the things like closing windows button on left side, global menu bar, and now I actually enjoy it. Also Unity is one of the faster desktop environments on my older PC, whereas Ubuntu Gnome is very sluggish in comparison.
Maybe then easing the restrictions on immigrant employees might be the solution.

Max 60 days of unemployment over your whole career, when many companies need a month to go from offer to starting, makes being fired a fatal affair.
H1B applications being cancelled, if someone switches companies means in the first few years, changing companies is even worse.

Oh, you've been working in the US for 20 years ? Hard luck, you still don't have a permanent residency because of some archaic system. No, your wife can't work in the US either. Also, you can't avail any of the benefits you already pay taxes for. You lose your job and your child is a US citizen ? Hard luck, take them back to where you came from. Because, having immigrant parents is a crime enough to banish even your own citizen.

The visa system is built to encourage abuse. Just because the trade off is worth it, doesn't mean it is fair
or a favor. It is a system built to be of maximal benefit to America. Which is fine, but let's not pretend it
is some sort of gift that is granted to people of other nations. It's the govt. driving a hard bargain because they know they can.

Now, my career does grow 2x as fast and I do make 2x as much by working in the US. I also do not have kids, partners or a life in the US, that it would destroy me to leave the country. I am also fortunate enough to be in a company that doesn't usually fire willy-nilly. So, I continue to stay. But, in 5 or so years, I wouldn't be too sure.
I graduated with a History degree in 2008. Had zero job success, a couple of years later went to a tech school for 2 year Computer Engineering Technologist diploma, the rest is history.... no, wait, the rest is programming.

I’m curious if anyone has any direct knowledge about that.

There are so many professional activities similar to that where no one makes any money and people really just do it for the love, and then there are seemingly similar things like that where people make surprisingly large amounts of money.

It was not strictly a logic class, but more of an overview course of discrete math, logic and proofs, and some statistics. They taught -> I think.

I've never heard of "sequent calculus" before, and I don't expect anyone I know to have heard it. Apparently it's not calculus.

> They used to say "the US has the best high schools in the world; unfortunately, they're called universities". But the universities have become so watered down that many Americans get university degrees without ever passing through an institution at the level of a good gymnasium.

I don't think universities are watered down because they don't teach notation that most people don't know and find obscure. My university is famous for a difficult admissions process, tough courses that most people only learn 2/3 of the material, and grading curves calibrated so getting 60% on exams is enough for a B or A.

https://en.wikipedia.org/wiki/Sequent_calculus

Wikipedia says "Sequent calculus is one of several extant styles of proof calculus for expressing line-by-line logical arguments."

I didn't learn "every statement is conditional" logic involving turnstiles, I learned something where the assumptions were given in the problem, and each line was proven based on the previous lines, which boiled down to the initial givens.
I’m genuinely curious as to what one of these job descriptions look like. I’m not at all doubting the existence of this sort of behavior.

I can't recommend Manjaro Linux enough. It's the desktop system that got me off of Windows due to the sheer ease of installing software and maintaining a stable system, which I've done now for 2 years on 3 different boxes.

I've been trying out Linux desktops since the late 90s and this is honestly the first system that didn't eat itself after an update.
Funny how different people come to different conclusions. I have a Book 2 and I regret it almost every day. The dock constantly runs out of USB resources, when I detach the tablet the external screen configuration gets f...ed up in random ways forcing me to rearrange screens and font sizes for a few minutes, the tablet mode feels very awkward to use and for its spec and price the Book 2 is not very fast.

My company also HP Zbook laptops. Next time I will get one of those those again instead. Not a very elegant laptop but it works.
There's just not much of an article to write about what the virus generally does. They lay out the typical course over two paragraphs near the beginning of the article: it infects the lungs, and gives patients a progressively harder time breathing, until either their immune system fights it back or their breathing is too impaired.
I can't find it at the moment, but I remember a graph that showed the price of goods over a period of something like 30 years. Things like clothes, food, gadgets, cars, etc., we're shown to have decreased in price. Things we actually need like education, medical care, and housing had risen astronomically. So even if the dollar itself doesn't inflate much, it still can have significantly less buying power, as you say. What's worse is the cheapness and ubiquity of gadgets serves to mask the problem by making everyone think they have more wealth than they really do.
"Usually fast enough" is unfortunately the only guarantee a preemptive multitasking OS can give you. Unless your system is guaranteeing your program x cycles of uninterrupted processing per frame of audio and you can consistently process the frame in that amount of cycles, the only mitigation is to deliver frames in large enough chunks that you never run out of time in practice under agreeable circumstances.

That said, I agree that the question of what "real-time" might mean is irrelevant given the context.

Even pulling out the sim wouldn't help. Without sim the phone can do emergency calls, so the phone is still connected to a network (afaik).

My paranoia is fulfilled with switching the phone off (before leaving home), but others would rely on removing the battery. Snowden recommended putting it in a fridge.
> In order to connect to the VPN, you must connect to the cell towers, which reveals your location.

It reveals the location of an anonymous SIM with no readable traffic, connecting to an unknown (if you use Tor) and also stationary and anonymous device, which might be planted in any random school, library, workplace...

> And no matter how many burner phones you use, as soon as you visit your home address, your identity is compromised.

Of course - don't do that with the phone on :) that's the basics, isn't it?

Furthermore, we have 75k dead. If we think we've peaked, this means we lose another 75k on the way down. And of course nobody with any opinion worth considering thinks we have peaked. So it looks like we could easily break 200k... If people weren't spending money out before, it'll be twice as worse.

TL;DR If you don't fix the biology, you will not get the economy sorted. This will just make everything worse. Totally backfire.

No. Wasm is still executing on a virtual machine, and native compiled go code will still be native.
It is completely irrelevant, given the context. The only, only, only thing real-time means here is “can be run on a live signal passing through it” rather than “is a slow, offline effect for a DAW”. No hard real-time, no soft real-time, no QNX, no pulling out the college compsci textbook. There IS real-time in that sense in DSP, it just isn’t in a VST plugin.

I’ll repeat again that any compsci theorycrafting is not the concern here, and real-time has a very specific meaning in DSP. Computer science does not own the concept of real-time, and the only people tripping over the terminology are those with more compsci experience than DSP. I appreciate everyone trying to explain this to me, but (a) I understand both, and (b) this is like saying “no, Captain, a vector could mean anything like a mathematical collection, air traffic control should learn a thing or two from mathematics.”
There is indication that it will not, in that the teams that designed both projects sit next to each other.

One thing that is happening: Kubernetes is designing a new set of ways to define how traffic should be routed in a cluster, to replace Ingress (https://kubernetes-sigs.github.io/service-apis/), and Istio is going to sit on top of those. You'll see this in "experimental" in the upcoming Istio 1.6.
For anyone planning to try this, don't forget about impedance matching and use a transformer/active reamper. Some pedals may react very differently.
It's probably easier to run a JS script to mine crypto than a virtual machine to run a video ad though.
“Re-open the economy” talk has reached levels of collective delusion that I honestly find frightening. And it’s not a partisan issue either.

We have the example of successful responses in places like South Korea and Taiwan, none of whose standard the US seems intent, or maybe even capable, of meeting. Instead, people in the US cling to phony performances of leadership by their various authoritarians, whether it be Andrew Cuomo for Democrats or Trump for Republicans.

..or, business could open with the precautions they're taking and .. nothing happens. We see the same fatality rates, grow a little, lower a little, but generally level off.

It sucks it's come to this, but all of the states with lock-downs are desperately looking at states easing restrictions to see if these shelter in place orders are really worth it. We've heard that many of the people in NYC getting infected now are getting infected at home.

I'm really hoping that Texas and Georgia, as they slowly open up, do not go over hospital capacities. We already know a number of people haven't gone to hospitals when they needed to; as many cut off access in preparation for a surge that never came. It's equally likely these states may not see a surge at all, even post re-opening.

Yes, a lot of people may still die, but this virus is in the environment. A lot of those people would die either now, or six months from now. I don't understand how people can think complete eradication is even possible. You can't limit people's social contact forever. We are not laptops that can be placed on standby for a year or gears in a machine that can be stopped and oiled.

Microsoft Azure Sphere’s $100K IoT Hacker Bounty Challenge
Good writeup. I was in same decision process some half a year ago, went with 2070 super at the end. At that time, Nvidia was marginally more powerful (10% on average), had much more quiet implementation (Radeon heats up much more by default), and had raytracing (questionable but still an added bonus). Price difference at my place was maybe 50$ between most quiet 3-fan variants. So at the end, pretty much same price/power ratio.

Went with Nvidia since noise under load was very important, and for windows their drivers are generally are super stable and just work (don't have that great experience with Radeon from the past). Good to see Radeon side catched up, we all benefit from competition.
>Experts urged caution, suggesting the report may be based on limited commercially available mobile phone data, and that there could be other reasons for varying levels of phone usage.

Is there much more to it than this? Much more will be read into this than should be. Investigate by all means, but everyone should really know that there’s only one answer that the present US administration is interested in with this investigation - that this virus did not develop but was released - the good intentions of researchers be damned.
To Mark's credit, he's down in the muck replying to their (batshit crazy) comments and throwing it right back in their faces.
The problem is that you might get a lot of instability.

The most obvious case: stack 20 boxes one slightly above other and let them fall.

If you will have random noise in there the simulation can become unstable/explode.
Posts like this are published with regularity. And like all things that must be said again and again ("stay off the grass", "we're in this together"), we can assume the opposite somehow true: Most teams do not write much or do not write well.

What posts like this do not address is the root cause of the problem: Writing is hard. Why is it hard? And how can people learn to write better? Those would be worthy topics for a longer post, which are not addressed in this one.

Writing, like code, takes time to produce and consume. Like a product with friction in its onboarding, this decreases the likelihood that many people will ever reach the goal of writing clearly.

Unlike code, most people think they can write. But the difference between writing, and writing clearly, is large.

Unlike code, almost everyone has been "taught" to write, often by teachers who themselves do not write well, or do not have time to truly teach them, so they have a lot of bad habits. These include a reliance on cliches, ambiguous diction, and poor organization. The first flaw makes the reader zone out, the second vastly increases the amount of time it takes to consume and respond to writing, since the feedback loop is delayed.

Personally, I do not believe that many people will ever learn to write well; I also don't think it's worthwhile to make them try. I think that organizations, in order share information well internally, should make certain people "writers" who get extract information from their colleagues and convey it to the team. They would be like the secretary in a meeting, but more ubiquitous. This would be part of their job description and KPIs and compensation.
I know it's probably not "Russian bots", but...

Two of the comments post the same CDC 2017 list, and both come from twitter accounts with 0 posts (one is 100% retweets of anti-"liberal" content). I'm never sure how plausible it is for someone to have the time to sit on twitter all day just to RT these things and then jump onto rando blogs to leave long comments like these.
Of everyone doing this, I think that he should have more sympathy for those struggling during this time. Don't hire people to find violations. Help out people that are starving

Well for starters I wouldn't have lost sleep over an arrow. (Even ⇒... blasphemy, I know.) Instead of, you know, a 3-way intersection sign making me wonder why I need to look both ways before crossing. Or, you know, they could just use a couple keywords from some actual programming languages from this century or get things going in plain English. Maybe "is" or "instanceof" or whatever. Then if you really, genuinely think your readers need to obsess with your formalism (which they very likely don't unless they have the basics down and are also planning to get a PhD in a proof theory-adjacent topic), you can switch from the 21st century English and math notation into cuneiform and hieroglyphics.

(You can probably tell I didn't enjoy the experience...)
Assuming this is true knowing that there is no way to definitively find out, would it have been possible for China to limit the spread at the time? If is was true and they were open and transparent about it?
Thanks for the info! Did some reading and I can see plain reverb being time invariant indeed :) I never realised chorus pedals did more than just stack frequency offsets onto your signal, but I only really play distorted so choruses are of limited use to me.
