The record separator isn't on people's keyboards, so it's less likely to show up where it's not expected. Also it's less likely to legitimately occur in something like a name, so there are many users of CSVs who can

We might have different ideas about what constitutes a tutorial. Online tutorials vary massively in quality, but something like the official Python tutorial https://docs.python.org/3/tutorial/ is a fine resource.

Tutorials include some code which is intended to be exemplary and simple enough for a new programmer to make sense of, so I wouldn't discount it as a part of reading code. Practical code does not always have those properties, although

I think you misread their claim - they said that generic list/set would have to be classes, not modules (generic modules are a specific thing in OCaml and aren't the same as a module of generic classes).

Because the beam coming from your eyes and hitting a shadow would never reach a light source (you could say it gets absorbed before it reaches a light source).

by penteract 2y ago
Until you can observe that light doesn't travel instantaneously, it would be consistent to believe that a beam leaves your eyes, bounces off a surface, and informs you (as though it were a limb, perhaps) when it hits a light source.

I'd read "moving in one direction with Brown motion" to mean Brownian motion plus a linear term. If margin trading causes you to lose the asset, its value goes to zero, hence log of that could be said to be negative infinity.

That's great. What's the first guess? And does this prove that there is no way of identifying the answer in 2 guesses? I tried running a version of your code across all targets, but my current machine isn't up to it (and ther

I wouldn't be surprised if there is a way of doing it in 4 guesses (3 to identify and a 4th that's known to be right), although you probably need to adjust the later guesses based on the results of the first. It wouldn't be i

The score is floor(100*(1-distance/max_distance)) where max_distance is the greatest distance to the target from any point in the cube. This means that the spheres used in triangulation look funny. Rounding also gets in the way, but yo

I didn't have a formula, just a Javascript object with 4096 keys. You could try to use a formula, but the rounding would make it quite blurry, so an "exact" answer wouldn't necessarily be right.

It's calculating distance in 3D space, scaled by the longest distance available. Without the scaling (and ignoring the rounding for the moment), distances from the target to any 3 non-collinear points would narrow it down to at most 2

I swear that #516 looks darker than #505 (although perhaps only against a background of #505 with #808 next to it). Something interesting is going on there with my perception of saturation.

The Balrogs were Maiar, a category that includes the wizards (Gandalf, Saruman, etc.) and Sauron. The Balrog Gothmog is there, but not the one that appears in the Fellowship of the Ring, possibly because it isn't given a name.
