One problem that remains for home 3D printed lenses is chromatic aberration.

Refractive index(angular multiplier for lights entering at angles) is wavelength and material dependent, which means magnifications/focal distances vary for each colors, causing rainbow-blurred images at image planes. btw this is obviously how prisms work.

The variance is largely monotonic and the effect is well studied; the coefficient of this aberration is called Abbe number or Vd, defined as Vd = (nD-1)/(nF-nC) where nD, nF, nC is indices at 656.3, 589.3, 486.1nm respectively. Materials that shows Vd > 50 is called "crown" glasses and materials with Vd < 50 is called "flint" glasses. There are lens materials with Vd of exactly 50, such as Fluorite(CaF2) crystals as well as other engineered materials such as borosillicate "Extra-low Dispersion(ED)" glasses. These lenses show abnormally low aberrations, at cost.

Wikipedia[3] explains the legendary Carl-Zeiss Tessar design by Paul Rudolph as follows:

> A Tessar comprises four elements in three groups, one positive crown glass element at the front, one negative flint glass element at the center and a negative plano-concave flint glass element cemented with a positive convex crown glass element at the rear.

Without relying purely on such exotic materials, lenses are designed with pair and triple elements(doublets and triplets) to counter aberration. A convex crown glass may be used to focus light, then convex flint glass lens are added so as to cause focal point for both red and blue lights to coincide(achromat, or non-chromatic, doublet). Or an another convex lens can be added to force RGB lights to converge at a same point(apochromat triplet, APO). Focus errors dependent on wavelengths follow an exponential curve to the power of lens count. An achromatic doublet consists of Schott BK7 and Schott F2 is often used in textbook exercise questions.

There are other types of aberration such as "the five Seidel aberrations", and some might be able to be solved by clever use of same materials, but as far as I understand, chromatic aberration cannot be solved by computational force alone. Maybe it's something dumb and obvious to materials scientists as adding certain baby powder with specific composition into the resin, like how obvious a UART console pads are to PCB designers, but for now this rules out high quality lens manufacturing by direct stereolithography, as there is no hobbyist known way of controlling and modifying Abbe number for UV resin materials, save for using metamaterial surfaces. If someone could dump that here it'll probably be a decade worth of progress, for both hobbyist photography lens creation AND likely for entire optics industries as well!

Which episode are you referring to? What specifically did "this guy" say that was illegitimate? For someone who's not a regular listener these vague allegations are quite annoying because it's impossible to tell whether you have a valid point or are just trying to push something for political reasons.

Given how low they are already stopping, they likely have a dedicated team for chargebacks that will fight tooth and nail to challenge it.

I am currently dealing with a chargeback team for another company, and the amount of time they’ve dedicated into challenging me likely exceeds the chargeback value itself.
Which distributions and which settings are you talking about?

If you can run gdb on that distribution, then you can definitely do it, even if it's just because they whitelist gdb in selinux/aa (in which case you can just script gdb). And I rather doubt it is a default, since ptrace-based sandboxing is a thing (even Firefox was using it).

And as for the second method, that's why I said same home directory. But there is a gazillion of ways. You can even meddle in practically all IPC done by any two processes of the same UID, e.g. attach to sysv or posix shm.
No. Mammoth DNA has been sequenced (15K years old). Perfect conditions for preserving tissue, small fragments can be extracted. Since all cells have the same DNA, fragments that are long enough and have low enough base error rates can be aligned to reconstruct longer fragments (really the same thing as regular shotgun genome assembly).

I would expect if you could find ancient (1Mya) tardigrades preserved as tuns, they could probably be extracted and sequenced.
I like your thinking! A couple of points:

(1) we don't really know the threshold yet to be beyond repair I think. It may be 1% but may be 20%.

(2) as others noted, it's 15 years for 0.1% damage using your math.

(3) your timeline directly contradicts the article doesn't it, which suggests keeping people in ideal conditions would have a DNA half life of millions of years.

(4) it's not a given that you need to wake people up to repair DNA. Maybe you just need to bring them to 1 degree Celsius or something. Or maybe nanobots can work on you while completely frozen. I think we are quite far from knowing right now.

So yes, for long term travel DNA repair will be important but how it actually works I think we know little about.
This is a very common question, and understandably so. It can be surprisingly hard to defend a general principle on ethical grounds. Principles are justified by observed regularities. Good principles do not necessarily lead to correct actions in 100% of circumstances.

The principle of “don’t interfere with the free exchange of ideas” is one such example where it is particularly hard to see the justification. The consequences of speech suppression are usually subtle —- how do you quantify the impact of a conversation that didn't happen? And at the same time, the consequences of allowing hatespeech or misinformation are usually not subtle, but rather immediate and relatively obvious.

I think we’re actually lucky because the Joe Rohan example does contain examples of good justifications. For the past two years, Rogan was openly discussing politically inconvenient inconsistencies, contradictions, and in some cases retroactively apparent lies by the establishment. It is good to know when your leaders are incompetent, when they are lying, or even when they have made a mistake and never taken responsibility for it! It is good that these conversations happened and good that people know this information.

But even if we can see that this is good, it’s still one of those abstract good-for-society things that is hard to quantify and hard to weigh against the consequences of its counterfactual non-existence. It is thus almost impossible to balance against the harms of, for example, supporting vaccine skepticism. But that’s not an argument for suppression, merely an acknowledgement that this is hard to think about clearly.

But it is a fallacy to say: Joe Rogan’s vaccine skepticism is getting people killed, therefor he should be silenced. The reason is that living in the sort of society that would silence Joe Rogan also gets people killed. The deaths are just abstract deaths.

Put it this way: image we get into a war in five years because Rogan and all the other independent voices like him have been successfully soft-pressured into not talking about the downsides, while the mainstream propaganda mouthpieces have been selling the war hard. Thus, we create a concrete terrible outcome because we allowed a culture of speech suppression. Unfortunately, even if that does happen, it will not be obvious that speech suppression led to war, because, again, general principles tend to have more subtle but far-reaching consequences.

There are also well-known edge cases where speech suppression is probably obviously the right thing to do. I personally think that the genome for smallpox should never have been published, because try as I might, I can’t imagine a scenario where the harms of suppressing the specific knowledge outweighs the possible (even likely) consequence of its dispersement. You can have a principle while being cognizant that tradeoffs can be valid.

Again, though, the reason why free expression is weirdly difficult to defend, is that the harms of “bad” free expression are usually immediate and clear, while the harms of speech suppression are abstract and distant.
There is a concept that we don't interfere with each others lives. If someone has views you don't like, and he never forces them on you, you gotta let it go. For example, a bunch of people chose Jesus, and an other bunch chose Mohammed. Long standing tradition so far was to accept this, and let it go, because alternative is a literal war. Violence. Nobody wants violence, so there are even laws that make it illegal to deny service because of one's religion. And it's not a little deal, for religious person it's about eternal life, so someone believing in wrong god is hugely offensive. Coming back to Spotify, there are a bunch of people who hold beliefs which are considered incorrect, and they are being marginalized and excluded from all avenues to express themselves. It's not Spotify, it's Facebook, YouTube, Twitter, and pretty much everything else. When it's a single business that decides to exclude Christians, it's one story, but when it's an organized campaign, then we have a problem, because there will be war
I don't get much out of Joe Rogan but I love JP.

A lot of what you say, I read it and say it's actually very consistent with him believing it.

People who suffer delusions often aren't stupid or even unconvincing. A lot of that intellectual effort you're describing, piecing together plausible details to justify their falsehood, can go into it. Someone I know who suffers these issues had a reputation in the family for being creative, a good storyteller... The hospitalizations and psychiatric diagnoses came later.
The people who think Rogan is a shock jock don’t watch him because they think he is a shock jock. It is a self-reinforcing idea.

So much of this outrage seems to be coming from people who don’t watch Rogan and simply base their opinions on second-hand information.
It sounds more like you’re angry that someone is refusing to publish on the platform they own something you personally politically associate with?

Which hey, I get. But they are refusing to publish it because they don’t want to be associated with it anymore, and they bought exclusive rights to it from producer, so…

And I don’t see Joe Rogan saying he is in a hurry to return the money Spotify gave him for this exclusive licensing deal either.

The only real way I can think to ‘solve’ that problem would be to make it illegal to do exclusive licensing deals for content.

Which I personally would be behind (it is also at the root of the whole streaming provider wars, among many many others), but has very far reaching consequences intellectual property wise.
Also, consumer protection laws. I smell a pile of fines and lawsuits in their immediate future.

As I understand the charge back process, vendors are generally assumed guilty until proven innocent, and it's not going to be worth Adobe's time to fight these. On the other hand, it costs credit card companies a boat load of money to acquire customers, and failing to issue legitimate chargebacks is a great way to lose customer. On top of that, the bank makes more money from a chargeback than a legitimate charge.

I've successfully issued charge backs against Experian, for example. You can't get much more in bed with the credit industry than they are. (Though the operator at the credit card company did say that Experian was responsible for about 50% of their caseload that year...)
Do you think any of these would work for a 3-year-old?

This is 3 days after Jen Psaki said from the white house podium that disclaimers are a good "first step", but that "we" (the white house) want to see "more done" by tech companies.

Now spotify has complied with the government's wishes. We're now beyond "but it's a private company...", and indeed into censorship.

The primary goal of documentation is to make code easier to understand, not to copy code or to puzzle the reader. If the documentation doesn't help, then it's useless, so it must be deleted, or it makes readability worse, so it must be deleted.

It's in parts based on MSYS2, but doesn't give you a "full install" (or whatever is the best way to phrase it).
You're right here, they won't be able to charge you automatically via the credit card, but you're still legally obligated to pay for the subscription since you have agreed to the terms of service during sign up. Depending on the action that they would take, you could easily end up paying a higher amount than the original subscription price if they put additional charges on you...

That’s an interesting aspect, which I haven’t thought of. I think real world lava lamps have very chaotic behavior. I think the neural network, however, just learns the most common behaviors of a lava lamp but so far cannot learn every aspect of a lava lamp. Training a bigger neural network could work though…

> GIMP is pretty darn good

GIMP could be pretty darn good if they gave 20 UX designers another 10 years to redo their entire UX. As is, it's a usability nightmare. Whenever I'm forced to use it, it feels like I spend 70% of my time fighting with the horrible UI, 25% of the time Googling how to do trivial things because it's very much not obvious, and 5% doing what I actually want.
That goes down the road of saying that every circular path is an orbit. I'm reminded of the concept that the sun "orbits" around in the milky way. I don't really consider that an orbit either because the dynamics are totally different. I try to use "orbit" in relation to objects moving around a larger mass and/or a barycenter, which is conceptually a location of average mass. A third tiny object is rather in an orbit around one of the the bodies but that which is constrained by the gravity of the second.
I was not trying to conflate two things, I was mostly trying to highlight and ask about how we govern orbits that don't abide by national land boundaries.

I'm not sure how it wrecked credibility, as I don't think I said that getting rid of light pollution would have no effect—I feel pretty certain that without light pollution, one can see so much more of the night sky.

That being said, yes, I was unsure to which extent, once light pollution was minimal, that satellites would obscure the view, mostly to the naked eye. I know that sometimes when we cut out signals, others will appear more prominent, as just as when the house is quiet I hear the fridge and other sounds that I wouldn't normally here.

So if the satellites aren't that bothersome to the naked eye (or to cameras and astronomers) then I'm relieved to hear that and grateful for you pointing that out.

I still think the main purpose of my OP was to ask about how we govern global spaces with national governments.
"If you aren't familiar with the work and impact of Neil Young"

What I find hilarious is the number of folks of a, certain political persuasion (the fact a public health issue is politicized is absolutely nuts), have deemed Neil Young and Joni Mitchell as irrelevant dinosaurs from an artistic perspective. Some even going so far as to say their historical importance is of a mere footnote.

Of course the firestorm their actions caused in the public discourse on this issue has shown their voice matters quite a bit.

Were actual binding commitments made, Russia would have inherited them as successor in interest. But no one pushing this Russian propaganda line can point to anything that even remotely resembles even a personal (much less binding international) commitment, just a few instances around 1990-1991 where Western leaders indicated that they (depending on which statement or communication it is) either were not immediately prepared for or did not immediately envision further eastward deployment of troops of expansion of NATO.
"Optimal" in this context means it never repeats the work of beta reduction when it doesn't have to. Ie, evaluating `(\x -> x + x) (2 * 2)` only evaluates `2 * 2` once.
X is the private corporation forecasting that it would lose too much money if it continued broadcasting those episodes.

There’s also a step 0, which is the private corporation predicting it would make a lot of money if it could exclusively broadcast Joe Rogan.
CRTs are very different, absolutely. I also observe this sort of thing on the original Game Boy. Spaceship shooters frequently used white space with black stars since the obvious opposite would be an indecipherable mess on the DMG's display. They also use flickering content to add more shades due the low-pass nature of the slow display response. Game developers and artists have always been great at getting the most out of the hardware and I strongly believe that part of preservation has to be preserving the input & output devices.
Yup, was just trying to give an example that utilized primitives to make it easier.
You seem to operate under the presumption that content and culture generally can only be created on major platforms. Nothing stops creators from finding other spaces to post their content. It's what sub-cultures have done pretty much throughout time -- find alternate spaces to explore ideas that might be outside of the mainstream.

It's not like Spotify is sending hit squads out to shake down artists that don't join the racket, or harass studios and sites that host content they disagree with.

There is a lot you can do with a big microphone, but perhaps the Internet isn't and never will be the utopia that people imagined it would be. In a different world where large tech companies were completely hands off and governments embraced a speech free for all, many people will still feel that they don't fit in mainstream spaces and will need to find another forum.

That's like saying you should divorce after the first fight or argument.

Or because it makes no rational sense to just completely end his ties with spotify or for spotify to end their ties with him at the first signs of pressure from the social justice machine?
