    Their balance sheet looks very healthy for a growing company with a strong gross margin and very sustainable net losses relative to the capital they've been able to raise. As long …

    From their S-1, 2020 revenue was $219m. From that, $106m was cost of revenue, $87m went out to SG&A, and $55m for marketing. Presumably if they wanted to hit pure profitability, th…

    PCA is a cool technique mathematically, but in my many years of building models, I've never seen it result in a more accurate model. I could see it potentially being useful in situ…

    I believe that the real intention behind the statement is that not all users of their product are going to have 5 working fingers if they've had some sort of accident or similar.

    Agreed with all points. I often find that these sorts of observational studies with weak methods that provide evidence for something the unblinded study participants would want to …

    I found myself wanting a little more content here. Felt mostly like hand waving followed by a plug for their product.

    Fine, but you could just as easily flip the arrow or come up with a common cause to come up with a plausible narrative. In areas with low economic growth, lawyers are a high status…

    Looks like a fun side project. In a similar vein, I'd also recommend the Synacor Challenge, which involves a set of gradually expanding challenges around implementing a virtual mac…

    STL files are the 3D models that you put into your slicer of choice (which converts the project into the thin layers that the printer will gradually put down). There's a dozen thin…

    To be clear, I'm genuinely curious - this isn't intended as an insult to any of the folks who have worked on these projects.

    Part of the difficulty SO faces is that there's sort of two similar but distinct problems that it's meant to solve, and as such there is no one "community". It's simultaneously a p…
