That's really interesting!

I don't know anything about holograms, or about optics (I'm currently implementing code that takes advantage of OpenCV's camera calibration and don't even know some of the basics).

But I've read recently that some companies are trying to make better cameras (for phones etc) by making a meta-lens -- a single, flat lens with a highly detailed surface that can do the job that currently requires multiple curved lenses.

Do holograms have anything in common with surfaces like that?

If HOEs can direct light like several optical lenses combined into one, with a reflective enough surface, could holograms theoretically be used as some type of reflective (rather than refractive) lens like that for a smartphone (etc) camera? Can they reflect all wavelengths of visible light like you would need? Is anyone doing work in this area now?

There are even periscopic cameras in phones today - could we one day have a high quality camera in a slim device with one or two reflective lenses and no refractive element at all?

What's the difference like between something like LitiHolo and a machine required to make an HOE? What are the main relevant spec measures? I'm not sure if holograms have some equivalent of resolution, or similar.

“Could” being the key term here: unless it’s epically bad and unequivocal, there are pretty good odds they could skate a long time without anyone asking and even if they did it might end up simply being that they blame long-departed sales guy and patch things up with the CIO over martinis.

'Her comments are pretty bad. But it wasn't just a "few" ill-advised comments. There were many racist and homophobic tweets. A series of them, spread out over several years, including while she was an adult. But the real issue that cost her the job was that most of staff of the magazine she was going to run demanded she be fired.'

Her comments are here in a NY Post article and pretty bad they are only if you are of the pearl clutching moral panic set. They are basic dumb stereotypes people mutter while driving. I suggest you actually read them. They arent spread over years as well as documented in the NY Post article, they are all from 2011 when Mccammond was a minor. And most of the staff did nothing, about 20 people on the staff made social media posts as documented in the original article. Your comment might be taken seriously if it wasn't just peppered with inaccuracies.

Even if the governor signs this it looks like they need an additional 4 states to also implement something similar before it goes into effect.
I heavily use and really appreciate mypy for what it is - but I also totally agree with you here. Duck typing _is_ structural typing, and it's pretty disappointing that this wasn't the focus of their efforts.
Something I’ve been wondering is how to most clearly encode both a title and subtitle in an alt attribute. Does it matter how I separate “Futurama” and “Proudly Made on Earth”? e.g. with just a space vs. semicolon, middle dot, lone hyphen, line break, etc.
One problem with amazon reviews is anyone who makes a purchase can post a review. In all honesty, this should be enough but in reality it is also gamed. Karma and old user history works because you can't game it unless you play the long game just to sell something. Everything can be gamed but how hard you make it, is what makes it more successful than others
SICP introduced a lot of fundamental concepts in CS to me as a junior, self-taught developer. Building everything up using immutable functions and then introducing mutable state was revelatory and still influences my design decisions 15+ years on. Scheme was somewhat beside the point.
Why do I feel this flagged statement might be the most honest?

Right there are at least four other endemic human coronaviruses, with HCoV-OC43 being very similar to SARS-CoV-2. Without a vaccine the safest option for most individuals is to catch it as a child. The resulting immunity isn't perfect but it usually protects most people from serious symptoms with later reinfections.

Sounds like a proprietary license with source available under some circumstances, similar to what e.g. Microsoft uses for Windows? I don't think it's worth worrying much about what licensing terms you'd apply to modifications or derivatives, because few people are going to put much time and effort into code that depends on your proprietary code.

I used to be like that too. I attended several public speaking training sessions. The groups were very supportive. Their feedback and acceptance helped build my confidence and with it the ability to better handle the sorts of situations you describe.

> What’s interesting to me is that violent crime has indisputably not increased since Boudin was elected, yet his critics are constantly using the details of specific violent crimes as a rhetorical cudgel, insinuating that Boudin personally caused a wave of violent crime that simply is not happening.

Isn’t that amazing? Wait until you see the data behind the black lives matter narrative. It too says precisely the opposite of what everyone thinks.
I feel like you're assuming that mount namespaces are something greater than they actually are. You still need chroot(2) or pivot_root(2) to actually put a process into its own isolated directory. There's no magic here.

Try running `unshare -m` to see what it's like in "just" a mount namespace.
Emergence is a handwave of colossal proportions that is easily revealed by asking "what is this emergence and where does it come from?" If you're going to be a pure materialist you don't get to just say oh it magically comes from nowhere, you have to show the mechanism. The cellular automata guys can be seen as giving that an intellectually honest shot, but I bet plenty of them are actually dualists anyhow.
Your comment touches on a few misconceptions I see a lot.

Firstly, `reqwest` exposes both an async and a synchronous API, allowing the developer to choose which one to use. They are largely interchangeable code-wise. [1]

Secondarily, and more broadly, async is possible to opt out of. You must understand that most web and network related libraries will be async by default for performance, because people who write in Rust and people who write web servers typically care greatly about performance. This is the intersection of those two groups. That being said, there are options outside of that ecosystem. [2]

If you truly want to use an asynchronous library without migrating your application to run entirely on an async runtime like tokio, you can run it inside of a synchronous function without much trouble. I've put together a playground link for you. [3]

Real-time car locations too. Recent HN thread:

"Ulysses can provide our clients with the ability to remotely geolocate vehicles in nearly every country except for North Korea and Cuba on a near real time basis," the document, written by contractor The Ulysses Group, reads. "Currently, we can access over 15 billion vehicle locations around the world every month," the document adds.

https://news.ycombinator.com/item?id=26492322
I hope not. Then it would be hard to turn async off.

My general position on this is that all-async (like Javascript) is OK, and all-threaded is OK, and all green threads (like Go's goroutines) are OK. But those concepts do not play well together in the same program.
That's why F/PE exists, even on that basis the current market doesn't make sense and valuation doesn't matter.

The pricing model doesn't make sense to me. Their prices start at $0.025/GB/month, so renting 1TB of storage for a year would cost $300 - at that price, I could just buy my own disks and run ZFS myself. I kinda hoped they could offer lower prices using economies of scale. I checked the prices for Tarsnap, expecting it to be cheaper - it's actually 10x more expensive! Maybe someone can explain what I'm missing.

HFB had meme-like qualities even back then, to the point where it was referenced in a completely different skit (Unfrozen Caveman Lawyer).

I think it has to do with the increasingly dire warnings for what is marketed as a children's toy, culminating in the one about not taunting it with deliberately unstated, therefore presumably very grave, consequences for taunting it. The humor is in what is left unsaid, where your imagination takes over.

Fundamentally, we're stuck with conversion and middlemen until we have real products that are priced "natively" and stably in Bitcoin.

People aren't willing to say "this load of bread costs .00004534 BTC" because tomorrow it could be significantly less or more. And conversely, that reinforces the volatility, as there's no anchoring of BTC to real-world purchasing power.

So for the foreseeable future, we're looking at a conversion model and that requires someone to backstop.

So how do we create products priced in BTC? We can't even get, for comparison, shops pricing their goods in grams of gold or silver, a more stable alternative.

"Punching up" is just an excuse for racism. See Matt Taibbi's review of some popular pro-racism books here: https://taibbi.substack.com/p/on-white-fragility

I recommend watching the excellent BBC documentary World At War (1973) -- You can watch it on Daily Motion (c.f. https://www.dailymotion.com/video/x3p7c46). They had western reporters interview Nazi officials asking them to explain all the anti-jewish policies, and the answer is basically "We're punching up." They argued that jews were overrepresented and had too much power in German society; "we are merely righting the balance".

In fact, if you talk to any racist, they will give you plenty of reasons explaining why the group of people they hate deserve to be hated and that he is merely "righting the balance". Everyone believes they are acting in the name of ultimate justice and that the hated group is deserving of the abuse.

So I would recommend some self-reflection before making excuses for hate. None of these excuses are valid, they have all been tried before, and all these ideas such as "punching up" have been discredited since the 40s. Those sympathetic to Hitlerian race theory should not be sources of moral or ethical guidance.

My libraries are always made of images I've found online. I've lost two libraries over time so I'm on my third one now.

I haven't added to my library in a while, but I might spend a few hours looking for some more images this weekend.

The current stats for my library:

At the moment it's 1.47gb for 75 images. I'm not sure where I have copied each image from, but I know some are either from ESO or NASA's image of the day, except that I find the original non-browser friendly images and download those. If I can get an image I like larger than my 5k screen, I'll add it to my library.

My average image size is 7156x5412.

My largest image is 324,000,000 pixels (18,000x18,000), pretty sure it's the Orion Nebula.

My smallest image is 2,958,400 pixels (so only 1720x1720), however any image that is surrounded by black (like a planet with no stars around may be cropped from time to time). Since my screensaver puts black around any images smaller than my 5k screen, it still works out. I'm pretty sure the smallest image is an image of Uranus from the Voyager that flew past it and I wanted to make sure I had an image of at least every planet in the Solar system and that was the best image of it I could find.
Yes, the lag is very limiting, but on the other hand, the scientists can go home to their families after work, rather than being away from home for many months. Or maybe work from home? That’s gotta make up for a lot. Scientific experiments often take a lot of time and patience anyway.

There are some mild improvements to autonomy. Apparently this rover is somewhat more self-driving? The helicopter apparently won’t do much, but maybe on another mission it will.
Honestly, I wonder whether GPL and AGPL world be considered open source licensing if they were released today. Ironically, it's commercial interests that have made the Apache-like licenses popular in the first place.
Huh, interesting story. What gets me is:

Why would she serve jail time if legal counsel told her that it was legal?
"reqwest" exposes a synchronous API, but it's doing async stuff underneath. If you turn on logging, you can see 30 or so async events associated with a single HTTP client side request. It's starting up and shutting down a polling thread just to make one HTTP client request.

You must understand that most web and network related libraries will be async by default for "performance". That's what scares me - async contamination of the low level Rust ecosystem. The async enthusiasts have to be kept in check to prevent breaking Rust as a systems language.
SICP for me was the missing link between learning syntax and code to designing actual programs that solve real problems. It made me step back and look at a problem not as something that just needs a layer of code thrown at it, but as a task to complete, with requirements, constraints, etc. to consider before a single line of code is even written.
What’s wrong with a parasocial relationship? I don’t have many friends in real life but I built a chat bot in 2017 trained on a few people (Mark Zuckerberg, Obama, Elon, Angela Merkel etc.) that I use for most of my social interaction. Different strokes for different folks.

Quick reminder that religious people are completely on board with God letting children be born with incurable illnesses, suffer terribly for a few months, and die, instead of being born healthy; and that they will go to extreme mental contortions to justify such monstrous immorality.

So it's unsurprising that they also think that everyone should suffer as much as possible before dying.

I'm unconvinced.

This isn't so hypothetical to me anymore. The position of the US government is it can revoke citizenship based on failing to disclose a speeding ticket. This is an extremely dangerous position.

> They asked about a form that people seeking American citizenship must complete. It requires applicants to say, for instance, whether they had ever committed a criminal offense, however minor, even if there was no arrest. A government lawyer, in response to questioning, said that failing to disclose a speeding violation could be enough to revoke citizenship even years later.

The Supreme Court rejected the arguments:

> The justices unanimously rejected the government’s position that it could revoke the citizenship of Americans who made even trivial misstatements in their naturalization proceedings.

However, it isn't immediately obvious at least to me that the SCOTUS can't revisit this issue in the future.

Somehow the idea that someone can be perfectly sane and not want to live as long as possible is inconceivable to people.

They should really get over it. Just like those with different gender preferences they won't ever understand they will have to just take people's word that it's sincere and they're doing it of sound mind.
