"Indian" land is a meaningless term. When the Sioux fought with the Anishnabe over the Great Plains, whom the Anishnabe occupied earlier than the Sioux, who deserves that land? Do we owe reparations to the Sioux or to the Anishnabe? Presumptively, another tribe controlled that territory before the Anishnabe. There never was this concept of "owned, stable land" until modern times. The way of the world was more like you only got to keep what you could defend. This is why Europe is dotted with massive castles. 1000 years ago, a Viking party could end your town's existence in a single raid. This map is not representative of what is "theirs by treaty". This map is a rough outline of rough territories (some notably overlapping among the individual tribes) from some arbitrary point in the past. It's not relevant in the year 2020, sorry to say. No more so than a map of individual territories of the Germanic tribes of 200 years ago. The native American tribes do enjoy semi-autonomy in various territories across the U.S. and have even contributed to the development of the United States, with native Americans fighting alongside all the other races in nearly every war we've ever engaged in, including the Civil War, Spanish-American War, World War I, and World War II. They are U.S. citizens and part of this country. Rewinding the clock 200 years is not helpful or productive.

Never used WhatsApp, but is it related to Apple policies? I just ran into something reminiscent of this with Microsoft's Authenticator app - runs on both platforms, supports backup and restore, but apparently on Apple devices it's only able to use iCloud for backup rather than an associated Microsoft account.

The net effect is that if you're switching you have to redo 2fa for all accounts where you haven't separately backed up your TOTP codes.

Ask HN: Mandatory National Service, would it make politics less polarizing?
Today's politics in US is overwhelmingly polarized. I'm not very familiar with pros/cons of mandatory national service, but am wondering if that wouldn't help people, as they enter adulthood, realize they're PART of the government and that it's not necessarily an adversary.

EDIT: Just to clarify, by "national service" I don't necessarily mean military.

Which "entitlement"? The one expressed in the idea that you owe nothing to others, or the one where others should expect something of you?

Why is one "entitlement" and not the other?

In either case, there is no logical fallacy present. And the question is independent to the question of freedom which is secondary to the question of moral constraint.

Ie., establishing what is moral in our interactions with others (murder, theft, etc.) is prior to the question of freedom -- freedom is whatever remains to be maximised when moral constraints are in place.

The cause of "freedom" is therefore often rather a meaningless one. Everyone is pro-freedom except the "freedom to do what is immoral". And so the question is only ever really, "what is moral?"

Ie., what we owe to others, and what they owe us supersedes any particular political programme.

Yes. Amazing how many people are content to makes presents of such dross to their young friends and relations.

RAII-based memory management without GC, and the concept of ownership vs. borrowing are very C++-inspired concepts. The borrow checker, which is the main innovation of Rust, is automated checking of things C++ programmers spend a lot of effort thinking about.

The task of disambiguating speakers, relative to skill at other audio processing tasks, is more similar to disambiguating superimposed faces, relative to skill at other vision tasks.

It is not similar to quickly recognizing several different faces that are present in a video stream.

Tasks requiring simultaneous processing of focused attention on multiple input streams are not very related to human visual or audio processing. These types of tasks are not similar to attending to things in peripheral vision or peripheral audio.

I actually (embarrassingly) got tripped up by that a bit.

So, you're saying that radians/degrees _are_ a unit because we can use them to describe a count of something, but they're still in fact dimensionless?

Is that because 2*pi or degrees never refer to an actual physical length? I think that's what trips me up because I generally have thought of degrees and radians as essentially units of length around a circle. But I suppose that since we're working with circles of arbitrary rather than specified diameter, they're still unitless.

I think I got to it on my own at the end there ha but I'm happy to be corrected!

>there is no simple symbolic path that is human understandable towards human level intelligence

I imagine that, piece by piece, if we really wanted to, we could look at the 175 billion parameters in GPT-3, test which are 'active' when this poem is written, which are active when that imitation of copypasta is active, and through a torturous interrogation, find that one particular parameter, say, is for weighting the 0.001% likelihood that you would use an accented é during a particular rhetorical flourish in certain contexts. Perhaps another parameter codes a meta-meta-meta abstraction about how a meta-meta rule governs a meta-rule for how to use a sometimes-used linguistic rule.

And the totality of those 175 billion parameters could in principle be uncovered and described in ways that are satisfactory to humans. It would be tedious and unproductive, and akin to the project of archeologists patiently, tediously uncovering a dinosaur.

But the point is it would be practically difficult, not something forbidden as a matter of principle.

More importantly though, is that I don't think the supposed incomprehensibility to humans has relevance to anything. What's the argument supposed to be? Humans don't depend in any explicit, conscious way, on having conscious grasp of our own tacit knowledge. I don't know why I unconsciously shift my weight a certain way when going up stairs. This doesn't stop me from walking up stairs. And it doesn't stop us from making machines that could walk up stairs.

We need neural nets? Okay, sure, we need them. But we can run those on machines that, at the end of the day, are silicon and 0s and 1s, which are every bit the brute, formal systems that supposedly can't model intelligent things. Weren't we supposed to have encountered a barrier to what computers can do at some point in this thought exercise? Because it appears that what began as an extremely bold claim, that computers can't do X, Y, and Z, ends in a whimper, as a vague exhortation to appreciate that neural nets are in some sense structurally different from logic design. Nothing about that latter claim is making any bold statements about the limits of what computers can or can't do, which makes me feel like the argument forgot what it was supposed to be about halfway through.

How can this be implemented? You can go with the javascript approach of "you can only read the clipboard contents during an user interaction", but there's nothing preventing the app from reading the clipboard every time you touch the the screen. A lot of sites use a similar exploit to bypass popup blockers. You could make so the user must accept an OS modal before the clipboard contents are released. It's more secure, but it's jarring and slows down the user.
This.

AWS has always been eager to get on the phone with me to discuss cost savings strategies. And they don’t upsell you in the process.
There are also more upfront costs (not just monetary), you can't scale quicky, and you lose all the managed solutions that make building things super fast and effective. Your hardware cost may be lower 10x but the operational and developmental cost will be higher as well as a limit on your business to grow.

A balanced approach is to only put the most expensive hardware portion of the business with the smallest availability requirement in colo, and horizontally scale it over time. Simultaneously use a cloud provider to execute on the cheap stuff fast and reliably.
You are correct, pushing you to tune in regularly is one of the worst part for me.
If u were gifted at math and wanted to do it all the time, would you a) get paid for doing it with peers while getting a PhD or b) work a job as a janitor to support yourself while doing math. With the amount of depth modern math has, i think to achieve results you need to be able to do it full time, so getting a PhD seems to be the most logical route for aspiring mathematicians. Not to mention that most pure math don't have much practical application at the moment, you certainly would not convince your manager in industry to let you solve random problems just for the sake of solving it.

Designer Tricks to Make Your Home Cozier
It is only natural that the right and left contradict each other. Since NAP is totally dependent on how you define property and the first people called libertarians were anarchists and socialist it would be more apt to say that right libertarians are still trying to argue that it isn't an outright contradiction. I tough that there was something more to this "contradiction".
> Surely, if it can filter heavy isotopes, coronavirus won’t fit through.

Surprisingly, that reasoning doesn't necessarily actually work.

It turns out that there are actually several different mechanisms by which a filter can stop particles.

Big particles, for example, might not fit between the gaps in the filter--think fish in a net. This is called sieving.

Particles that are too small for sieving but are heavier than the surrounding flow keep moving in a straight line when the flow goes around the filter fibers. They collide with the fibers and get stuck. This is called inertial impaction.

The smallest particles that the filter can handle are not held in place by the fluid they are flowing in and so move around a lot by diffusion. This diffusion can lead them to hitting the fibers and getting stuck.

Particles too big for diffusion but too small for inertial impaction can follow the flow around fibers, but in doing so they can still hit the fiber and get stuck. This is called interception.

There are also electrostatic effects with some filter materials that can ensnare some kinds of particles.

When you put this all together, the result is that filters do not work the way we would intuitively expect, where there is some particular size and everything above that is stopped and everything below that makes it through. That would only be true if sieving was the only mechanism in play.

The curves of efficiency vs. particle size for all of the non-electrostatic mechanisms are S curves. As size goes up, sieving, inertial impact, and interception all go up, but at different rates.

Sieving's curve rising section is almost vertical. Inertial impact's is fairly rapid but nowhere near as rapid as sieving's. Interception's is much more relaxed.

Diffusion is also an S curve, but it goes the other way, being high for small particles and dropping for large particles.

When you add them all up you end up with a curve that is high and flat for small particles, then dips down around some particular size, and then rises back up to high efficiency.

There's some nice illustrations and graphs here [1].

This is why 0.3 microns is used when rating HEPA filters. It's around the size that is hardest for them to handle.

It also depends on the person, no?
I think you're right -- we mostly only talk to 1 person at a time.

Where it might be useful is automated live captioning (already a feature in Microsoft Teams), especially in cultures that favor a "high involvement" conversation style where people interrupt and talk over each other (vs a "high consideration" style where everyone waits their turn). This tech might help improve transcript quality.

In the article, under the subheading Why It Matters, the authors say this:

[Quote]

The ability to separate a single voice from conversations across many people can improve and enhance communication across a wide range of applications that we use in our daily lives, like voice messaging, assistants, and video tools, as well as AR/VR innovations. It can also improve audio quality for people with hearing aids, so it’s easier to hear others clearly in crowded and noisy environments such as parties, restaurants, or large video calls.

Beyond its separating different voices, our novel system can also be applied to separate other types of speech signals from a mixture of sounds such as background noise. Our work can also be applied to music recordings, improving our previous work on separating different musical instruments from a single audio file. As a next step, we’ll work on improving the generative properties of the model until it achieves high performance in real-world conditions.
This is one of the worst new trends. So many of the news aggregator apps will feature made for mobile stories where the most important aspect of the article would be a picture and there's only one picture at the end of an article, there's no picture, or the picture is from a tangentially related article that was linked incorrectly.
> COBOL is really, really bad from the point of view of a developer. It's frustrating, verbose, and tends to produce huge spaghetti code.

THAT is true of any language, the fact that COBOL has divisions does make it a bit easier. But you can also do very structored code in COBOL and code without using the GOTO verb. However many systems and code born the scars of the time. Fast code really did make a difference and was measurable in cost a lot more upon an expensive mainframe and when your processing near on a million records, very noticable in costs. So GOTO got used a lot, as coding for exception handling using structured programming like JSP (Jackson Structured Programming - the thing in the COBOL days) whilst doable, wasn't the fastest code and equally, not that readable if you didn't know the methodology behind JSP.

But over time you don't see the language, you see it from a data perspective and with that, code however laid out becomes easier to manage and by that, anybody else's code will look a bit yuk to you. Indeed it is rare to work on somebody else's code and come away with a warm fuzzy glow.

The point is that among the tribes, there never was constant territory. They warred among themselves, conquered each other multiple times over, and there were numerous atrocities committed by some of the tribes who claim to deserve reparations. For the record, I don't think any of this is productive for humanity, but since this has become a popular movement of the moment, let's disentangle this. When the Sioux conquered the Anishnabe, when the Aztec sacrificed humans from "lesser" tribes by the thousands [1], when the Mayans conquered other tribes and did the same, when the Iroquois tortured their conquests, what reparations are these tribes owed? If we're going to rewind the clock 200 years, why not rewind it 300, 400, 1000 years? Let's untangle all of humanity's historical atrocities and try to really see how far this rabbit hole goes.

Author here. Trail Router is a running route planner that prefers greenery and nature in the routes it generates, and biases against busy roads. It can generate round-trip routes that meet a specified distance, as well as point-to-point routes.

I've written a detailed blog post about how Trail Router works here: https://trailrouter.com/blog/how-trail-router-works/

I developed this because I am (or was...) a frequent traveller for work, and I like to run wherever I visit. But I don't enjoy running on busy main roads, and I found that without careful and time consuming route planning that is often what would end up happening if I didn't know the area. Trail Router is my solution to this problem.

After a previous discussion (https://news.ycombinator.com/item?id=23177351) received quite a lot of attention, dang reached out to suggest I post a Show HN to reach a wider audience.
