As for updates, the NGS have plate models that allow you to get the shift in coordinates at any given location[2] between two moments in time. Those models are in large part based on GNSS signal recorders called continuously operating reference stations[3] (CORS) which give actual movement at locations throughout the states.

For example, Bar Harbor, Maine, is moving at -0.0013 m/y north, 0.0020 m/y east, and -0.0009 m/y in elevation relative to the North American plate, and 0.0071 m/y north, -0.0153 m/y east, and 0.0001 m/y in elevation relative to the world[4].

The NGS is a remarkably good agency. See https://www.ngs.noaa.gov/TOOLS/ for more of their work.

Hey HN, I built an web app to download videos posted/hosted on Reddit.

It gets the direct links to the video & audio files and allows the users to mux/merge them directly in the browser.

Tech Stack: Vue.js, ffmpeg.js, Netlify

Reddit's API serves videos as a pair of Audio+Video files (also HLS or MPEG-DASH but we are going to ignore that). Making the user drag the downloaded audio and video into the browser[1] to mux them allows the app to get around the same origin policy and access the files without a server component[2].

[1] In Chrome, you can drag directly from the download bar that appears on the bottom.

[2] Making the app "serverless" was a self imposed restriction, muxing the video on the backend would probabbly make better UX.

I'm sure everyone discussing this article is aware that neodymium processing is very hazardous. But right now we're learning that "simple" oil & gas extraction is also extremely hazardous, that the hazards are completely ignored, that non-employees of the extraction companies are deeply affected by the hazardous waste, that the extraction companies themselves work very hard to make it appear safe when in reality it can make you very sick, and generally that oil & gas extraction companies do not care at all about the treatment of these people on whom they are dumping these chemicals.

But by all means, let's also talk about neodymium production in China to distract ourselves from what's going on in our own back yards.

I think I did hear brick-and-mortar stores complaining recently about having too many customers, and wondering whether there was something else they could do, something they hadn't thought of yet, to annoy and anger customers, maybe add a little friction to keep them from walking in the door. /irony

No but, ever since "the Schneier piece" [0] I've been thinking differently about this whole issue. It's about identifying you, and well, the store already knows exactly who you are as soon as you use your credit card. So does Amazon.com of course, though ironically they might not have an image of your face.

If you were going to that physical store and planning to use cash (or shoplift), THEN this affects you. Although even without "AI," you would still get captured on security cameras. So if your presence there became a matter of interest - let's say for example, to corroborate or debunk your alibi for a more serious crime elsewhere - someone would invest the time to identify your face the old-fashioned way. Like probably a subordinate of the senior detective on the case, watching hours of camera footage looking for you.

You can see how it was a series of small, slow, incremental steps, each one not necessarily big enough to create an uproar, that got us here.

You're not even putting any stakes on the table. That's such a safe bet. It's unlikely you'd even have a chance at losing the odds are so stacked.

There's a great talk on why functional programming is not the norm: https://www.youtube.com/watch?v=QyJZzq0v7Z4

The short of it is: network effects. Haskell, OCaml, SML... they've never had the benefit of being the exclusive language to a popular platform like the web, macOS, or UNIX. They've not yet had a killer app like Rails or Numpy/SciPy/PyTorch. They've certainly not been foisted on the market with a war chest of marketing dollars like Java and C#. And they're not an incremental improvement on the status quo with an obvious, easy benefit.

> Now, try to explain to a programmer what kind of object id is

That's a rhetorical exercise. You can take a random snippet of APL or Fortran and the outcome would be the same. Every language requires training and effort to learn.

I teach people Haskell and TLA+. If you think teaching people the value of a language like Haskell is hard you should see the blank stares I get on the first day teaching experienced developers TLA+. Interested folks will come around eventually and have their moment but it takes training and dedication to get there.

> was chosen not with the best interests of programmers in mind

I'm well aware. I converse regularly with the maintainers of mathlib and the community. I know the focus there is on building a good tool for mathematicians.

I still think they built an interesting programming language even if that wasn't their intended purpose. That's why I started writing the hackers' guide. The documentation on the programming side is missing and needs to be filled in. They still need programmers to build the tools, the VM, the libraries, etc.

It's niche. And I'm not even the least bit surprised you find it horrible. I don't expect Lean to take off with programmers. I think the ideas in it are good and there is definitely some good things we could take from it in designing the dependently typed programming language that does penetrate the market and over-come the network effects.

Either way I think the people proposing the challenges for Haskell programmers to solve have a good reason to do so otherwise we would have a hard time finding the motivation for it. We want to see where algebraic effects go because new users often complain that monad transformers are hard to learn and users of mtl cite many problems that a well-done algebraic effect system would alleviate. Dependent types would remove the complexity of writing programs that work with types and enable us to write more programs with more expressive types. If you don't see why that's useful then what do you think the community should be focusing on?

The deed is based on static landmarks, the only directional mention is from stone landmark to landmark (ie, walk North 120 feet to a landmark set 4 feet from Paper Street). No reliance on magnetic north. Allegedly when the village was laid out they sunk stone landmarks at the intersections of the original properties.
Symbi­Flow – open-source FPGA tooling for rapid innov­ation
Some related things about tectonic plate motions might be of interest to the HN crowd:

The surface of the Earth is tesselated into irregular tectonic plates that (mostly) move rigidly, with little internal deformation. Plate boundaries are geological faults (dislocations where the crust on one side of the fault slides past the other side), but there are also faults within the plate interiors, especially near the boundaries, that accommodate strain within the tectonic plates in 'deforming zones'. The rigid interiors of plates generally have strain rates at the nanostrain/year level, i.e. a few parts per billion or less per year. This means that the relative deformation (not plate motion) between say Florida and Denver is on the order of 1 mm/yr.

Plate motions are pretty constant through time, such that the velocities measured over 10 year scales with GPS and other geodetic techniques are quite comparable to velocities estimated over the past ~5 million years by looking at longer-term proxies such as the bar-code-like pattern of magnetic anomalies on the seafloor produced at divergent plate boundaries[1]. Within about 20 km of an active fault, or 200 km from a subduction zone, the instantaneous velocities have a lot of variation related to earthquakes, though.

The horizontal velocity of any point on the Earth's surface can be described as a rotation around another point on the Earth's surface, with some angular velocity; this is sort of a corollary or application of Euler's fixed point / rotation theorem[2]: the point is where the rotation axis intersects the Earth's surface (so there are two antipodal points, actually).

Because tectonic plates are mostly pretty rigid, the motion of plates on the Earth's surface can be modeled as a rotation around a single point, even when the plate is huge like the Pacific plate, i.e. almost a hemisphere. However as stated in the OP, there is no 'true' reference frame, so plate velocities are usually described relative to another plate as a reference frame, or just considering a pair of plates. We'd say that relative to the Pacific, the North American plate rotates around a point near Hudson's Bay, or equivalently, that the Pacific-North America rotation pole is near Hudson's Bay. To go from N. Am. relative to Pacific, to Pacific relative to N. Am, flip the sign on the angular velocity.

Therefore there is a bit of shared heritage between some aspects of graphics programming and tectonic geodesy, with respect to the mathematics of rotations, etc. However in practice the math is probably different (I'm not sure because I don't do graphics or game programming). For a good intro to the math used in this aspect of plate tectonics, see here[3].

In terms of the rates of the velocities, relative plate motion rates between adjacent plates are typically 1-10s of cm/yr. The fastest on earth is near Tonga and Vanuatu in the southwestern Pacific (north of NZ), at about 25 cm/yr.
