It's a really, really, really bad idea. dSLR lenses are designed for sensors which are 24mm x 36mm. Cell phone sensors vary, but a largish one might be around 6x8mm.

That's not to mention issues like autofocus.

There were a few attempts to bridge this gap, which attach a large sensor to your phone. The best-known ones are the Sony QX1 and the Olympus Air. They never took off. I think that was due to very poor execution. I though the Olympus Air was close, but had a few complete showstopper issues which made it unusable. A v2 might have done well, but instead, Olympus gave up.

A few cameras are getting improved workflows with interfacing to cell phones, so perhaps we'll get there another way.
That man is incredibly skilled. I did not even know a battery rebuild was possible. Thank you for sharing the video.
Small differences in flange distance are less important than is often thought in the photo-tech-gawking sphere because it doesn't per se limit the back-focal distance of a lens design; note how in most non-tele lenses the back element is inside the mount or protudes out of the lens mount. Flange distance is merely a property of the mechanical interface, not an optical property. E.g. some people argue that Canon RF has to be worse than Nikon Z because the flange distance is 2 mm longer, but if you look at the available designs both have lenses with a BFD of 10 or 11 mm.

The article mentions image-side telecentrism for reduced aberrations. This is another talking point often brought forth; "the big mount allows a rear element so big that it can cover the image sensor with a near-telecentric swath of rays". Again, if you do a reality check here you'll notice that the chief ray angle (the angle between the chief ray of a ray bundle on the image circle to the image plane; chief rays are those crossing the center of the aperture) in actual lens designs is nowhere near 0° and is instead somewhere between 35-50°. Part of that equation is certainly that microlenses are offset as you leave the center of the sensor, so essentially sensors are designed for a particular range of CRAs and will not do well if you go way out of that range. Like the wide-angle rangefinder primes usually did: putting these on a digital camera results in strange color shifts towards the edges of the frame.

Any other recommendations for stand alone units?
They're not really even in the discussion when it comes to being real replacements for DSLRs. Their sensor size is significantly smaller than even a crop frame dslr/mirrorless camera, and roughly a quarter of the size of a full frame camera.

This smaller sensor size means they're not going to be used at the prosumer or pro level, and that in turn means a limited selection of high end lenses, etc.

I think this is useless fluff. It’s essentially just a few compiler flags being changed. I’m pretty sure the Chromium engineers are very well aware of those and made the decision to use the one they did. I don’t know which ones, but opting for higher optimization has to have detrimental side effects.

Also, the lighthouse score changing?? Isn’t the entire point of Lighthouse to grade the website and not the machine the test is being run on???

To answer your question, the United States Pirate Party is pro-democracy, like all pirate parties. We believe a more representative democracy would be beneficial for all third parties in the US, and support various electoral reform policies to further that goal. We also believe in the longer term that liquid democracy[0] is the way forward. I do agree that this could be communicated more clearly on our site, thanks for pointing it out.

Honestly smartphone workflow are just bad for different reasons. The best UX in digital photography is found in Leica rangefinders and Hasselblad / PhaseOne detachable medium format backs (not really the mirrorless medium format Hasselblad or Fuji cameras which have the usual awful menu systems).
> What about the fact that you will need to spin up, migrate and possibly seed a database in your CI pipeline?

The database system I use can be configured to start up reasonably quickly, and can be configured to operate on memfiles to reduce io pressure on the CI system. In fact, testing against the full scale local database is the only supported methodology for this particular rdbms.

No doubt no doubt. As I mentioned, mocks or fakes might be necessary in a condition like this.

My team uses interception and error injection for this case. We still have the real backend, but requests can be forced to fail either before or after executing on the backend.
While it don’t necessarily agree with the first statement especially when it comes to the wider public health issue these aren’t contradictory.

Joe isn’t 21 he is in his mid 50’s and although in likely a far better shape than most people at his age and even a large portion of those in their 20’s it’s a different case.

Also his initial statement was about getting a vaccine not about treating the disease.

On an individual case basis the risk of vaccination might be higher than not getting a vaccination (again not claiming it’s true) however as far as the wider public health is concerned reaching herd immunity is important especially when you account for secondary effects like mental health and financial stability which all have an impact on one’s overall health.

Honestly the pandemic really made me think on and reconsider my positions on many issues.

For example I normally i would be for mandatory vaccinations for children and in fact I did and probably still do consider it child abuse if parents refuse to vaccinate theirs.

This however does not line up with the fact that other than for healthcare and social care workers I’m in general against vaccine mandates because I think it’s a step too far. I don’t think that the specific impact in this case is that terrible I just have major concerns when the state can force people to undergo medical procedures against their will.

And as of yet I still haven’t been able to reconcile these two positions. And I don’t know if reasoning like Polio is far worse than COVID is enough to reconcile this.

I mean if this was the Zombie apocalypse would I support the execution of those who won’t get vaccinated? Would we drop napalm on neighborhoods that have a low vaccination rate to save the rest?
yes. it will last for more than one month.

Or, the provider, namely the government, can write the code to orchestrate these API calls even if these APIs are managed by disparate entities.

It's not pretend like it's not a solved problem. It's just that you're trying to eliminate the central provider in this case and you want to replace that with a blockchain which is excruciatingly slow
I don't really see how philosophy is all that relevant. Maybe somewhat relevant, but AIs are not brains. In fact we use computers specifically because they aren't brains, for things that would be expensive

What's the track record in general like for "philosophy-driven development"? It has big marketing success like Apple, and Chuck Moore's FORTH chips have interesting low power capabilities, but 99% of the world seems to run on tech that's built using the usual tech thought process.

Lots of cars can automatically stop to prevent a collision, using what's probably just a fancy version of if(goingToCrash){dont()}, based on LIDAR, Radar, and ultrasound.

I usually hear nothing but praise from safety researchers. Unless there's some coverup I'm not aware of, it seems like It Works.

Why could the Tesla in the mentioned accident not do that? Why does it need to recognize a person? It just needs to know that it's bad to hit stuff that reflects radar.

Sure, maybe a prankster could toss some corner reflectors on the road and jam up traffic or something, but that's the price of safety, and AI has adversarial inputs too. Just add some redundant sensor types to make it harder or a manual override.

Choosing to rely on brain-like AI is philosophy driven development, assuming the brain is always best at every task.

Instead, we can change the task itself. Not "drive a car as a human would" but "Transport passengers with as close to zero risk as we can, at all cost".

AFAIK every other industry with that goal is using deterministic code on the level of GOFAI or below, with the exception of a very few deep learning systems to detect certain things like fire, probably combined with deterministic code as a fallback.

AI only needs to be like 95% reliable. With some of the advanced routing stuff they could do, weird stuff like cars randomly stopping for 10s isn't going to bother anyone.

Even an occasional missed speed limit sign or running a red light or not seeing lane markings shouldn't matter, if there is trusted deterministic code that makes sure it never hits anything.

Current self driving cars are making progress. What's actually missing besides the extreme level of safety people expect? They seem to be slowly getting better at working in varied environments and the like.

When was the last time your toaster tried to kill you? Are you worried autopilot will land a plane on your house? Why are we not aiming for that level of reliability, instead of emulating humans that currently have accidents all the time?

Rule based systems don't usually fail catastrophically when there is no rule, as long as they are able to detect that there is no rule. Then they just safely shut down.

Current cars already fail in various mechanical ways. The important thing is making sure nobody dies, not guessing whether something is a bike or a dumpster. All you need to know is it's a thing to not hit.
This is just goal post shifting.

They said something that I thought was clear: you need file locks with read() and write().

I think you misunderstood that to mean only mmap can avoid data races.

What they actually said was that using mmap allows atomics so you can avoid file locks.
Excuse me for this very uninformed question, but (D)SLR, as far as I can tell, is about using a prism to split light, to allow having a viewfinder.

Why does a digital camera need a prism for it, can't the digital sensor directly show the image on screen (or viewfinder, do photographers still look through a viewfinder?)

Or does DSLR stand here for any camera with exchangeable lenses? Does the article mean professional cameras with exchangeable lenses are dead?
Banks 2FA and Google Voice
Hi all. Help Please. Moved to IReland 3 months ago and moved US number to Google Voice. Tried to do a bank transaction adn Citibank are sending a 2FA text. Obvs now not receiving this (and until i read posts on here did not know why).

Can some one please let em know is there a way around this. Can I move from GV to another provider to receive the 2FA? The only other way around it is to get on a plane BACK to the US to sort it as I cannot get Citi to understand the issue!

PLEASE PLEASE PLEASE help!!!
This looks interesting. Can anyone explain to me why cli rich text editors seemingly died after DOS?
That's the key feature of the design - there is no _real_ optical viewfinder because there is no mirror & pentaprism, which would be needed to redirect the incoming light from the sensor to a viewfinder.

Some mirrorless cameras have viewfinders, but it's either a digital display of what the sensor sees, or an actual optical path that doesn't go through the lens system. In either case it's not actual light redirected from the lens. A few illustrations:

I don’t necessarily disagree with you about the DA, but it seems like in your specific case the problem is more that the police themselves are acting indifferently.
Over temperature? Nope.

Or to be precise, not well-engineered plastics.

There are a ton of games one can play. For example, one can mix something which expands by 1%, with something which contracts by 1% (which can also mean expanding in the opposite direction). Modern lenses do very well across temperatures.

Over time? At least based on what I've seen, older plastic lenses have not aged well. Of course, that means more sold products. A new lens will blow away an older lens if the older ones is plastic and slightly wobbly. Planned obsolescence.
> Ours has 4.5kW _per plate_

That's impressive. The top-of-the-line Bosch induction cooktop, which retails for $2500 USD, tops out at 3.3kW on the largest plate. The rest are all most like 1.7-2.2 each.

A four burner range that could pull off 4.5kW per plate would probably require a 100A 240V circuit. Woof.

The other day I learned Graeber passed away in September 2020 [1]:

> Graeber was married to artist Nika Dubrovsky. He died unexpectedly in September 2020, while on vacation in Venice. His last book, The Dawn of Everything: A New History of Humanity, co-written with archaeologist David Wengrow, was published posthumously in 2021.

"The other languages are new, derived and possibly closely related to Lisp." Scheme's first specification was in the 1970s some time [1]. From the perspective of 2022, that is not much younger than the original Lisp.

I have no idea. I was thinking about the Tesla Roadster and Tesla Semi, two products delayed with years and counting. I pre-paid the Tesla Roadster in full 2018-06-14 and was expecting it to be delivered in 2020, so every new Tesla project I hear about makes me a little nervous the Roadster will be postponed even further into the future.

> Also, we are talking about the unbanked: people who otherwise have no other state-sanctioned way to use financial services. Bitcoin first and foremost helps such people.

No. No it doesn't.

The main reason for a large portion of the unbanked population is that they are so poor that they can't even afford to open and maintain a bank account. But sure, "we require a person to have a smartphone with always-on internet connection to do anything useful and have egregious transaction fees in most popular chains" surely does help the unbanked.
It depends on what you want out of a workflow. As I'm getting older, I'm finding I like taking photos, viewing photos, and I hate editing photos. For 99% of what I do, cell for workflows would be great, if not for the privacy issues.

Google takes my photos, and sometimes shows me "this day 3 years ago" or a nice montage. I like that.

I like having raw files for that 1% of photos I will edit, but that's a much less important use.

Would be nice to see a new version of irc but it's going so slowly...
So by removing the mirror, you remove the lag in the camera systems making future camera's become more like human eye capture units which then has implications for AI development.
I have no earthly idea how "identity politics" is related to the demise of the arab spring. In as far as it may relate to the rise of authoritarianism in Eastern Europe (Poland and Hungary), it is by being easy foil for Victor Orban and his ilk (cf. "LGBTQ-free zones"). Even if one were to believe these neo-fascists wouldn't just find some other scapegoat, I don't see how it would morally justify a return to 1950s social policies. Throwing some people under a train in support of human rights seems to be the quickest way to defeat your stated purpose.

It isn't even obvious that "identity politics" is tethered exclusively to left-wing politics. Plenty has been written about the group of people that invaded the Capitol last year, and the only consistent characteristic of that group was being white. No, it has nothing to do with economics. It included a doctor making $ 650,000 p. a. as well as a group that traveled to DC on a private jet.

Hell, the major group of young reactionaries in Europe (until recently) had "Identity" in their name.

This text just seems entirely out of place, and I was wondering if I missed the (2008) in the title while reading it. There's nothing new in it, and it wouldn't get much attention if it weren't for the name.
No. _I_ want to know what we're talking about, as my original question clearly indicates.

You can do "lock-free memory based interprocess communication" with memory (obviously). There is no need to back this memory with files, certainly not files on a hard drive that you would otherwise access using read() and write(). Hence my original question.
It is indeed not. I'm not claiming that all problems are solved and that decentralized governments are easy or even possible. Just that blockchains solves some of the problems in that area.
When politicians hold the share of Alphabet & Facebook, are there any high incentives for them to introduce financial regulations?

Really cool. What technologies are you using to achieve this? We've also had to tackle stuff like this before, but I'm not sure of the optimal way of doing it.
It's besides the point that I was making that blockchains solves some of the problems with decentralized governments. Albeit, not all.

> No, it doesn’t make anything possible unless there is an enforcement mechanism.

I was trying to say it solves some of the problems, though I may have worded it awkwardly.
This position only works under the premise that the Approved Facts never wrong.

Nutrition is a prime example of where the Approved Facts have been wrong and have likely lead to earlier deaths for people and industry lobbies promoting their poisons. All of these supposed "facts" have been widely considered true in my lifetime:

"Don't eat fat because fat just clogs your arteries just like when you pour it down the drain. Eat plenty of low fat foods, and replace saturated fat with industrial seed oils."

"Sugar is just energy you burn off. It's pure calories!"

"Calcium builds strong bones! Therefore, you can never drink enough cow's milk."

"Breakfast is the most important meal of the day! You shouldn't skip breakfast even if you're not hungry."

"If you don't eat then you'll starve, your body will go into starvation mode, and your metabolism will crash!"

"Salt just raises your blood pressure! Never add salt to your food and only eat things that are low in sodium. The less sodium the better."

"If you eat too much protein then you'll destroy your kidneys. High protein diets are bad for you."

"Distilled water will weaken your bones and you won't get enough minerals! Never drink distilled water."

---

Although attitudes towards such ideas have been changing significantly, in my life I've had teachers, professors, and even doctors tell me these things. And they're all essentially wrong for the average healthy non-elderly person. There was enough scientific data available in my lifetime that authorities should have known better.

The only way that I was able to come to the conclusion that the bulk of generic health advice is wrong was that contrary information was available to me, even though you can almost certainly still find a horde of medical experts to say that I'm wrong.

If I couldn't hear facts and opinions that went against the mainstream, I'd probably still be overweight with prehypertension and possibly prediabetes. By now I'd be in even worse condition.

To say that people should only be allowed to hear the mainstream facts is the same as saying that you should only listen to health advice approved by Coca-Cola.

And yes, to a certain extent, there's natural selection. The idea that you can save everyone from themselves is the same as saying that we can bend the law of averages so that bell distributions no longer apply.
