There are mountains of evidence that we are on track for several degrees Celsius change by the end of the century. It's enough to make some large metropolitan coastal areas uninhabitable and huge swaths of farmland unusable. It will destroy the economy to uproot half the human population and move, and thus cause mass migration and starvation.

Beauty and the Beast: Smooth meets the Monster.

Let n be a positive integer and let R be the set of real numbers. Let R^n be Euclidean n-dimensional space. E.g., R^1 is the real line; R^2 is the plane; and R^3 is (approximately) the space we live in.

Let C be a closed subset of R^n.

In R^2, examples of closed subsets include a sample path of Brownian motion (as in the OP) and the Mandelbrot set. An example in R^1 is a Cantor set of positive measure.

Then there exists a function f: R^n --> R so that (1) f is infinitely differentiable, (2) f(x) = 0 for all x in C, and (3) f(x) > 0 for all x not in C.

So, smooth beauty f meets the monster beast set C.

Of course, the level set of any differentiable function is closed. But now we know that any closed set can be the level set of an infinitely differentiable function. So, we also know that there can be an infinitely differentiable function positive outside of C, 0 on the boundary of C, and negative on the interior of C. So, we know that for any closed set, there is an infinitely differentiable function that has the boundary of the closed set as a level set. Since a level set of a differentiable function is closed, we also have the the boundary of any closed set is closed.

The Brownian motion example was noticed by A. Karr.
I remember reading about Obama's election and the use of "big data" and "data science" to target voters:
https://www.technologyreview.com/s/509026/how-obamas-team-us...

The social media companies picked on that and ran with it. So, while Facebook is not exactly the paragon of ethical behavior, this is just fodder for click bait. If the same targeting had worked in someone's favor the article would have been "gave advertisers an edge over traditional advertising" or something.
If it is a loophole it is not legitimate. To keep business and trade IN ORDER it would be legal. I think some of the loopholes are “honeypot” just to capture potential intelligence.
I actually haven't. I will try later and report back. But I have a 60/30 connection (down/up) and am getting 26/5, after messing with settings (which strangely is using TCP instead of UDP). And yes, this is under 5G, and I've tried multiple servers.

>> don't think it's worth paying $1

Key word there is paying. A buck is fine with me, but I don't have a good way to offer it. I'm not giving you my credit card number, email or phone number; I'm not going to spend even 10 seconds filling out a form just for your site; I don't use PayPal; I don't currently authorize you to ever take any more than the buck I want to give you right now; I want a refund if the functionality doesn't work as described.

Has anyone made any real progress in solving this problem?
We talked about releasing more comprehensive proof of concept code, but ultimately decided against it. While helpful for other researchers, offering anyone on the internet a ready-to-use arbitrary captcha breaker seemed like a net-negative for society.

Check out effectuation.org - built networks of people who trust you/you trust, and solve problems for them.

i'm primarily a programmer not designer nor game dev - so a priori an ide that store program state in the ui is weird (e.g. fiddling with booleans by either checking boxes or setting procedurally). but that's fine - you just get used to your state being spaghetti. the real problem with unity is it's closed source and all of its goofy bugs and breakneck release cycle make for really nerve wracking times. maybe the real thing is you shouldn't build your software business around a closed source vendor.
If you are really short of ideas, just check one of the existing popular services which you use and see if you can offer the same at a cheaper rate. For ex: if a 'package delivery service' is charging $1 for delivering a package, see if you can provide the same service 50 cents cheaper, while maintaining the quality of service.

You don't necessarily need to burn cash / offer insane discounts to achieve it. Cost reduction can also be achieved by improving the supply chain to make it more efficient, thereby reducing cost. For ex: replacing paid software with free/open source alternatives, automating some of the mundane tasks etc.

I haven't used BTC in a long time but last I read transactions take a very long time to process because the blocksize is too small to contain all the transactions that took place.

> who, believe it or not, actually want to "get the f out"

It would be more noble to try and fix the culture, instead, since if all people that don't like backwards culture get the f out, by definition the ones who left are those that like backwards culture, thus ensuring it stays backwards forever. But I understand that people have right to take care of themselves first and don't owe anybody heroic effort on fixing a broken culture. Sometimes getting out it the best you can do.

Still, that does not mean somebody needs to change their culture so it would be comfortable for somebody else to move around.

> bigger countries

What's good in that, except more expensive and out of touch bureaucracy? Everything nice you can do in big country - like unifying standards, removing customs borders, etc. - you can also do as an agreement between small countries. But if (or, rather, when) bigger government wants to do something stupid - it would be nice for the stupidity to be contained. It is a basic evolutionary principle - monocultures are extremely fragile and one big mistake or one big adversarial change can kill the whole culture. Union of many diverse cultures is much more robust to both mistakes (culture that made a mistake goes down, and the rest take up the space) and change (again, cultures that can adapt poorly to a particular change, wither and get replaced by ones that can adapt well, but at least they not die out as a whole).

> in a small country, a local tyrant can really tyranize the s out of you

And in a big country, a global tyrant can really tyranize the s out of you, 100 million other people and 50 countries around you. See USSR.

> while in an empire-ish bureaucracy you can be free as hell

You obviously never lived in a tyrannical empire. I did (even though I had the luck of it being on its last leg by then). Not recommended at all.

> you get tons of freedom (as an individual) as a byproduct

No, you don't. Of course, in USSR in the 80s one was relatively more free than in NK, but it's just a peculiarity of specific time - in late 30s in USSR it was probably much worse than in NK now.

Is this a problem of people voting when they aren't supposed to, or a problem with the voting machines, or the vote counting process?

Unless the level of criminality by members the public in Chicago is truly mind-boggling (Thousands of people casting dozens of votes each), I'd speculate that the problem lies higher up the tree of elected and unelected office. Or perhaps in the counting methodology used to come up with the number of votes, and number of voters. [1]

This is exactly the problem, and it's a difficult one to solve. I've seen research suggesting that the cognitive cost of filling out payment forms and giving out credit card information makes it easier to pay $10 than $1, since it doesn't feel "worth" all that effort to pay only one dollar. Unfortunately this is part of what reinforces the market dominance of mega-retailers like Amazon, because if you already have an account with them, the cognitive cost of signing up has already been paid.
As a pedestrian walking in SF, I am almost run over in crosswalks daily, even while knowing that drivers will run right through them. Fix that and I’d subscribe to a companion app with a blank white screen for $5/month..
It seems both camps count lowering the cognitive load and faster feedback cycles to their advantage!

Good dynamic systems have long done live-coding against the running system with instant feedback. Even recent static languages like Rust and Scala have notoriously long compile times and thus slow feedback loops.

Also there's along tradition of querying the system for things like auto-completion / doc display.

The cognitive load of fancy type systems like Haskell's is seen as very high.

Bitcoin transactions have something like a $5 average transaction fee. You can offer less but your transaction won't get processed as quickly. Bitcoin is already slow at processing transactions.

Disclaimer: I don't use bitcoin. The $5 number is outdated, but from the graphs I could find in a quick search it seemed to be rising consistently.

Some very interesting points made in OP and comments.

I’ll add one about user experience. Obviously the big web corporations benefit from the natural advantages of scale.

But an overlooked aspect of what makes these platforms sticky is that they all, including Apple, work very hard at making their products easy to use. And these are complex systems (I find Apple’s attempt at maintaining a global user state baffling, just from a user point of view, working with such an unwieldy system must be insane.)

Though this is an old problem, I think it remains: product developers and engineers vastly over estimate a potential users willingness/ability to learn a new system.

This is a “threshold “ problem, with a binary outcome. If your service is “good enough “ you might get some traction. But if you don’t hit that threshold of usability, your efforts are for naught.

The challenge is that usability is often an optimization problem, where one might be inclined to see how the MVP does, before investing the extensive resources in improving user experience. It’s also a big advantage to already have a lot of users, upon which a company can test and iterate.

My main point is that the general public has not become more technically skilled. On the contrary, all this effort by Google-Facebook—Amazon is focused on making these services drop dead easy to use.

Even technically skilled people have limits on how much they can invest in using alternative, less polished systems.

No reasonable person with uncorrupted brain would ever protest such thing. Self-beclowining, as I said.

After six or seven click-throughs, I downloaded the PDF.

I haven't read it but skimming, I could see that there definitely were no formulas in it at all . Which sort of says, at best what it tells you is "we did this thing, which is kind of like X and kind of like Y with Z changes". Essentially, no way to reproduce or understand by itself. The first reference then had a link behind a paywall...

So despite lots of apparent explanation, it seems like what they're actually doing is essentially unspecified (at least to the interested layman). It seems like at best an expert in the field of "compositional models" could say what is happening.

Also, the paper is published under the heading of an AI firm Fremont, ca rather than folks in a university, with the many authors listed by initial and last name...

While I disagree with mbell's interpretation of the value of this header or how it could be used, to answer you're question pcl, yes HTTP 2 does support multiple streams over a single transport connection.

To me, I would say increasing efficiency (or decreasing latency) was a central design goal of HTTP2. So HTTP2 includes it's own framing, which allows multiplexing across the connection. This helps avoid the overhead of establishing multiple parallel connections to speed up page load, head of line blocking, running slow start on each connection, etc.

Seems like it wouldn't really increase the speed at which the resources would be rejected, because the spec is that the resources can only be preloaded and not used: they are advisory messages only. So a compliant browser can take the hints, load the files, but only "use" them after seeing the HTML and validating the hash. Then a faster browser could compute that hash in advance, as well as precompiling the JS, etc.
Yes, it might. But the truth is that in 3 weeks the traffic has increased and the only thing that changed was AMP.

I've been wondering whether the way the political war in the US will end will be by a devolution of power to the states, with things like abortion rights, immigration policy, drug policy, health care, the social safety net, and maybe even taxation and some trade policies decided at the state level instead of federally. Just a thought, but it has occurred to me.
