If you really are doing hard realtime--absolutely no dropped frames, hard limit of 11ms per frame every time. Then you basically have to program in a way that completely avoids GC. Or use an incremental GC that you run when you have time.

So many things in C# use heap memory that you are programming in C# but without most of the advantages. Why use it over C++ or C?

Also if you take a look at DOTS, there's quite a lot that would be very hard to replicate yourself if you are using Unity.

And yes object pooling is a good best practice. But it negates a lot of the advantages of having a GC in the first place, and it's a lot easier for someone to accidentally allocate memory in C# without realizing it. Unity has a lot that I take advantage of, so I deal with avoiding GC. However if I was using my own engine, I wouldn't use C#. Despite the fact that I love C#.
Our conscious thought. E.g. how many words can you read in a second, vs how many words can a computer 'read' in a second? Conscious thought seems to be the bottleneck in our processing, since we don't play these games unconsciously.

There's a saying in various anti-capitalist (Marxist, Socialist, etc) communities: there is no ethical consumption under Capitalism. No matter what you buy, just by existing in a Capitalist system, you are enabling exploitation and immoral behavior. It's built in and there's no way to avoid it.

That observation means the opposite of what it seems on the tin: since it's a given that any consumption under Capitalism is unethical, it's pointless to just continuously beat yourself up about how unethical it is. But since we live under the system for now, do the best you can given what you have. That isn't, however, an open invitation to ignore the consequences of your purchases. It doesn't mean buy Chik-Fil-A sandwiches guilt-free when there are less exploitative options available.

The converse is also true -- there is no ethical business under capitalism. No matter what business you work for or run, it's going to be to some extent exploitative by definition. Do the best you can. If you have to work at one of the big corps to move your career forward, that doesn't make you a hypocrit. But when you have the choice to support a less exploitative corporation, to support a more moral small business instead of an immoral large one, take it. If you have to work in an exploitative company, and you have avenues to change them for the better, take them. And while the tech industry is full of exploitative large corporations, and small startups who would happily exploit whoever they need to make their VC funders happy, make the best choices you can. Sure, there's no way to be ethical and work for those big tech companies. But it makes no sense to chastise their employees as hypocrites for making the best choices they can and push for progress.
If it's sticker based QR normally you just show your screen to the person behind the counter before you pay to verify recipient and amount.

Many payment QRs are actually dynamically generally on a POS machine LCD so you get amount and recipient on your device - so that fake sticker problem doesn't exist in these cases
It's interesting how few people are causing all this trouble. When you browse memegen, the "transparency-and-ethics" group, dory, and other places the complainers gather, you'll notice the same tiny number of names pop up again and again. These people are nothing special professionally. They're famous inside the company only for their incessant protests and outrage campaigns. It's always the same group no matter the issue. It's as if these people care about nothing except the thrill of fighting the man and they don't really care about the details of any issue so long as it lets them feel like they're fighting the man.

I'm confused about why the company continues to endure the internal and external PR hell that this small group causes. There is a simple and obvious solution that would address the entire problem all at once. Any other company would have employed this solution years ago. The vast majority of people just want to do work and make technology. A company shouldn't let a small group of its own employees interfere with the business of the company.

The dynamic range is there in a raw file. You just need to apply tonemapping the way cell phones do it.

My 2008-era 1Ds3 still crushes a modern phone (I have a Pixel 2) in dynamic range when processed properly, and a D7500 is even better still, not to mention the latest full-frame models like the D850 and such.

Phones do, counterintuitively, have the advantage in extreme low light because they're able to stack multi-second exposures very reliably. But then again, I'm comparing my phone against a 2008 camera... the very best latest full frame cameras might be on par (at an extreme depth of field disadvantage though).

I'm so ignorant about cameras but have been curious... Smartphone manufacturers keep adding additional lens. Is that simply to compensate for not being a standalone camera? Am I complete idiot for looking at standalone mirrorless/DSLRs and wondering if Google's smart tech + Pixel 4's multiple lens are going to eventually eclipse standalone cameras? (My goal is to eventually carry a camera and non-smartphone).

Depth of field is proportional to the aperture/focal length^2

For a given field of view your focal length must change for different sensor sizes so effectively you see a shallower depth of field.

While computational imaging is doing amazing things right now, I've yet to be impressed by any sort of portrait mode, they simply do a mediocre job at creating a realistic sharpness falloff and fail far too often at identifying the edges of a subject. Once they get it right however, they could theoretically do some absolutely amazing things by simulating different bokeh and as small of a DoF as you could ever desire.
"The decision was taken after a new scientific study warned it was not possible to rule out “unacceptable” consequences for those living near fracking sites.

The report, undertaken by the Oil and Gas Authority (OGA), also warned it was not possible to predict the magnitude of earthquakes fracking might trigger."

In Ohio, where I grew up, I know, home of the fault lines, right? We have had several earthquakes and tremors. Fracking, despite environmentalist messages to Congress, is alive and well. And the deeper the well, the stronger the earthquake.

The book Peak Performance goes into detail on this.

Exercise is a closer analogy. You can't really lift more until you lift near your capacity. A brief session is far more impactful than long sessions of a lower weight. Short bursts at near max speed improve your stamina than an hour long walk.

Mentally it works the same way too. Sometimes growth means just thinking faster, or being able to follow a train of thought deeper.

Knowledge wise, you should be reading more difficult, information dense books, and less articles, podcasts, light books. The lighter ones I find are trivia, they don't improve your understanding of the world much, but the essays, biographies, historical books, academic journals go far.

You do need lots of rest. It's not a bad thing to be stressed out, as long as you get plenty of rest.
>NFC chips have allocated uids -- QRs are mutable.

NFC is mutable too; the low-cost unpowered chips you'll buy are mostly write-once read-many, but an NFC device with host card emulation can largely be whatever you want it to be. I suppose it's analogous to a QR code displayed on a screen vs. a printed QR code.

> handwriting recognition

For decades, I'd write out the amount field as:

29
$1234 --

as I was taught that was the correct way to do it. Suddenly, I was getting dunning notices saying I'd only paid $12.34. This happened simultaneously across different accounts. Clearly, the software had changed.

So now I write $1234.29, and everyone is happy.

Martial arts are a great answer. And aikido can be a great martial art. They are both social and exercise. Plus, if you’ve been braining all day in a relatively self-directed way, it’s really sublimate your ego and front brain to instruction and kinesthetic puzzling.

People get wrapped around the axel of the effectiveness of aikido, but truthfully it’s great defense against dying lonely or of heart disease. At least at many dojos. Some dojos are less physical than I'd like, and some are more. I’m happy to be at a dojo that leaves me uninjured but drenched in sweat and out of breath (and I’m in pretty good shape).

The A6600 sensor first appeared on the A6300, actually, not the A6000, so it's "only" three years old. That said, they've bumped into the upper limits of image quality; the newer 26MP sensor (which you'll find in the latest Fuji cameras) actually performs worse in low light than the preceding 24mp sensors.

>Imagine how many iPhones Apple would sell if the sensor were not much changed from the 6s and the camera software not changed at all.

Honestly, very little of the advances in cell phone cameras since the 6s have come from sensors; it's all computational. We're up against the brick wall that is photon noise.

Finally, the A6600 is very much not a flagship. The A9 II is the flagship, at three times the price ($4500).

Slavery is so illegal in the developed world that it's not even an issue. When people engage in human trafficking, the law enforcement apparatus puts the full brunt of its power into punishing the perpetrators. The government spends substantial sums of money preventing these sorts of abuses.

The government wants to stop copyright infringement, but it doesn't want to spend any money doing it. So they implement regulations requiring corporations to do the policing and punishment of copyright infringement for them.

The result is that Facebook, Google et al have sophisticated mechanisms to cheaply enforce copyright at scale, without human intervention in nearly all cases, and the mechanisms to enforce human trafficking violations is the legal office where a highly paid lawyer personally receives subpoenas and manually complies with them by personally escorting the FBI into the server room to verify the chain of custody.

Dealing with countries where human trafficking is as illegal as j walking just isn't something Google has tools for. Highly automated ML mechanisms are fine for when the punishment is your content gets demonetized or taken down, but it's not fine when the punishment is twenty years in federal prison.

That's not entirely true. a) because kids are bad at assessing risk, even when it is obvious. Have you never seen a kid stuck somewhere they could climb up to but not down? My five year old sister managed to climb ten feet up a wall above a concrete floor, and then stayed there weakly sniffling 'help' until one of us noticed she was out of sight. b) because the old playgrounds often suffered from hidden dangers like rusting metal that could break off as splinters under the skin, which happened when I was about ten. I got a tetanus injection and then spent a week or more regularly soaking my foot in hot water to make sure any remaining rusty pieces weren't lingering in there.

Good point about solar just transferring the energy. Im not sure how practical it is to brighten so many constructed surfaces like pavements and roads it makes a big impact and is tolerable to live with. An estimate that only 2.7% of the worlds land is urbanised, and 2/3rds being ocean... increasing its albedo significantly could be difficult. An advantage of space shading is it doesn't rotate out of play and can be concentrated a bit away from the edges of the globe where light is a bit more likely to reflect away.

Agreed it would be difficult and heavy to add minature gyroscopic and solar cell, comms and control unit to the 16 trillion disks proposal, since they are just 60cms wide. That plan seems basically like throwing confetti into L1, where it might get drifted away by solar ejections, out of stable orbit, in matter of years.

Since each of those disks is 1 gram and about 0.25 square meters, that scheme involves total of 4 trillion square meter shades orientated randomly. If shades are squares for simplicity and 8 meters in diameter, so 64 meters square and similar material would be 256 grams, add some stiffening and a control unit for say an extra 150 grams. Maybe a clever unfolding feature like an insects wing. Its a bit more material to launch but probably less than double at some control/shade ratio, and the tracking shades will block light about 30% more effectively than randomly orientated ones. Works out around 50 billion of the 400gram 8 meter wide shades with mini solar-comms-gyro units to produce. So I'm still overconfident in the practically of this kind of scheme, especially since cost to space has been minaturised since they previously had expert attention.

I have to admit its just one of those hunches Im hawking of late, cheers for following :)

Not sure exactly what you meant, but that sounds terrible.

On my Nikon DSLR I can adjust just about any setting using physical buttons, very fast, most often without even taking my eye off the viewfinder. The camera UX is optimized for speed and efficiency.

On a phone, I'd be scrolling through touch screen menus to do anything. By the time a shot is taken the subject is long gone (unless it's static scenery).
fair enough, I didn't think about the character limit
“Hard times create strong men. Strong men create good times. Good times create weak men. And, weak men create hard times.“
And, despite the a6600 not being a flagship, if the light is anything less than perfect, it will take pictures that are plainly higher in quality than anything coming out of a phone.
