You can try find workaround, change to alternative service, build your own service (I'm not implying that its easy), or just simply accept that.

that just means the reviews skew lower, not that they need to be 'corrected for'...

If a good product has 1K 'bad reviews', and a crap product has 10K 'bad reviews' - the system it working.

Anything else is just gaming the system to inflate review scores across the board.
This is all presuming your average retail investor doesn't get cold feet and drop out.

This is, unfortunately, going to be a situation where the sophisticated investors win out, and the people they cajoled into buying stocks will be left holding the bag. Gamestop could not reorganize quickly enough to assure investors that they actually have the ability to capitalize on this influx of investment, especially not with a historically terrible business performance.
> Meshes and bezier patches are boundary representations with no information of the volume they enclose

Pedantic on my part, but SDF is still just a surface/boundary representation at the end of the day. It may have additional benefits that you point out such as quickly computing if you're inside/outside or being able to more easily deform the shape (through any number of procedures including slicing), but you'd probably use a density grid instead of a SDF if you're dealing with anything volumetric, such as clouds or smoke.

> You don't. I didn't notice render times, but "interactive frame rates" would be lacking.

Yeah definitely, poor wording on my part.

> Most SDF primitives and their compositions are not analytic (from use of abs, fract, etc). Differentiation by finite differences is most common. Few are using automatic differentiation. I don't quite follow how back prop would produce the surface gradient, but I doubt it would be faster than these methods.

I don't think we're talking about the same thing, I'm not referring to the surface gradient when I say differentiable rendering.

Both differentiable rendering with an SDF (i.e. SDFDiff https://arxiv.org/pdf/1912.07109.pdf) and with a neural SDF(DIST http://b1ueber2y.me/projects/DIST-Renderer/) use automatic differentiation to compute the gradient of the rendering/image-generating process. Section 3.4 in the DIST paper discusses where back prop comes into all of this. Basically your surface is defined by the weights of some neural net (i.e. a neural SDF) and you need to know the gradient of your image with respect to those weights.

For a variety of reasons, these surface representations are easier to handle than triangle meshes which break certain desirable properties for differentiation and require extra care as a result (see edge sampling https://people.csail.mit.edu/tzumao/diffrt/ for an early example of the challenges of doing differentiable rendering with a triangle mesh).

I spent all week working on a project task, then I was told to refactor it, then they wanted to re-refactor it back, and not just revert the change. I think I'll leave it until next week.

Quite a few piled in during the last couple of days when GME was over $100. There could still be a lot of losers.

> ... you generate a new fictional long position from the loaned shares which gets additional voting rights without any conservation law.

That’s not how it works. Votes don’t magically appear.

The lender gives their voting rights along with the stock to the short seller. The short seller gives it to whoever purchased the shares from them. So only the final purchaser gets to vote, the original lender lost their rights while their stock is lent out.
OR they didn't it because a small percentage of their users were causing them a lot of grief for little gain and they decided to stop them for the long term benefit of their customer base as a whole (as well as for the operating model). I'm willing to bet if you dig through their TOS they are allowed to do such things. Whether it's legal or not I guess we'll see what the SEC does about it.

The book "The Trap: selling out to stay afloat in winner-take-all America" discusses the effect of healthcare on entrepreneurship:[1]

> It's a truism that American culture celebrates entrepreneurs. The opinion polls show exactly what you expect: Americans are incredibly entrepreneurship-minded. A 2005 survey showed that 28 percent of Americans have considered setting up their own businesses, compared to only 15 percent of Europeans. Yet the employment statistics reveal that Americans are far less likely to actually do it — 14.7 percent of the European workforce is self-employed, compared with only 7.3 percent of Americans. American entrepreneurs are clearly being held back from pursuing their dreams.

Robinhood Instant is not the same thing as a margin account. You're thinking of Robinhood Gold. FINRA rules say you can't open a margin account with less than $2k.

Margin investing is offered to eligible customers through Robinhood Gold, a suite of premium investing products including Nasdaq Level 2 market data and Morningstar Research Reports, for only $5 a month. The first $1,000 of margin is included in the $5 monthly fee. After that, customers pay a flat 2.5% yearly interest rate on any amount used above $1,000. Our pricing is straightforward and the same for every eligible customer, regardless of their account size.

One critical piece methods miss is they can't decentralize contribution. For example, the gganimate package in R gives user new ggplot functions. With a `+` users can use functions from any package, so the gganimate approach works.

With method chaining the gganimate author would have to mutate some class, and users would have to load all methods (vs importing what you need).

- They automatically liquidate your options positions

- They don't let any retailer buy stocks(i'm not even talking about options/leverage).

- They only let retailers sell only (to hedge funds).

- Then they come up with the " clearing houses" explanations...sure..but the price moved in the "right" direction right? Probably the hedge funds shorted even more as the bet was sure: block them from buying and the stock surely won't go up!

- Good news: the situation in monitored and "limited" trading will be allowed tomorrow...probably enough to make people dump the stock and let the hedge fund managers cover their naked shorts.

Let's hope the retailers will not get scared off, hold their ground and push the hedge funds into gamma squeeze!

Why not?

It fits the definition from the article. “An industry in which high infrastructural costs and other barriers to entry give the largest supplier in an industry an overwhelming advantage over potential competitors”

In case of FB the infrastructural cost is less of an issue, at least not anymore. I think Amazon and Microsoft are capable of hosting at least a dozen Facebooks each on their clouds should they want to. The main barrier to entry which causes that overwhelming advantage is network effect.

The first thing I did was to pop up inspector and see if the author's blog is using this new molasses service. It does not -- but I guess this is ok, it is just a blog after all.

The next thing to check was to head www.molasses.app and see if it uses it's own services -- turns out it does not!

docs.molasses.app ? nope

www.molasses.app/signin ? ah, here it is, finally! Here are some examples of the feature flags they have, for the curious:

"New login experience" / "a login experience that includes google sign in" / active: true

"test headline" / "Tests the headline" / active: true

I think they are just saying the data is more likely to be secure if it is recorded at your doctor's office, which seems reasonable to me.

Let's say it is a blood pressure reading taken by your Fitbit and uploaded to Google's servers. That data is not subject to HIPAA regulations. When your doctor takes your blood pressure and records it in your chart, it is subject to those regulations (as you say, it would be wildly unethical for them to sell it).

Separately, even if the two scenarios were subject to the same regulations, I would still expect the doctor's office scenario to be more secure. I think that any given patient's home network/device/security practices are more lax than those of most healthcare organizations.
That's fair, my point is that if you only care about rendering something quickly then a mesh is your best bet.

Are there applications you have in mind where the distance to the nearest surface is actually useful, regardless of the surface representation? As in, when would knowing the distance to the nearest surface be helpful when you're working with meshes? It seems to me you only need to know the closest distance to a surface when you have an SDF and are trying to compute an intersection along a ray.

The nearest sort of application of this kind that I can think of is Walk on Spheres (cool recent paper https://www.cs.cmu.edu/~kmcrane/Projects/MonteCarloGeometryP...), but in that case the authors do a closest point query, not a distance to the nearest surface. There's a subtle difference here because you actually need the closest point (not just the distance) so that you can look up a boundary condition. It's not clear to me how you could make use of an SDF in this setting, although maybe there's an interesting research direction there.
