QUESTION
I am learning to program a game engine which is why I followed a tutorial, with that tutorial I have gotten this far and even though my code is identical to theirs (theirs did work in the videos) its not working the way it is meant to. The triangle stays black no matter what. There is not any errors.

I'm not able to understand why the promise is not resolved when the condition it's true. In my case, I'm working with Puppeteer and I'm trying to do scroll down to charge more google reviews. I select all container childs and the total of reviews. It's the same number, but it seems like that condition it's not true. I understand nothing...

QUESTION
I have just starting learning python and am trying to make Wordle. This is what I have done so far with 'gWs' being the variable for the guessed word split into a list with each letter of the word being an item in the list. 'cWs' is the same as 'gWs' but for the correct word which is randomly selected. The code compares whether each letter of both words are the same, in the word or not in the word. I can't figure how to make it so that if the word guessed has 2 or more of the same letter and the correct word only has one of the those letters, then it outputs that one letter is in the word or in the correct spot, and then the other is not in the word.
...ANSWER
Answered 2022-Mar-21 at 08:17First of all, use better variable names - there is no negative to use words instead of 3-letter-acronyms.
Then change your code so it uses loops and enumerate for the checks.
Put the checking into a function to reuse - return the build string.
Don't print with end="" - instead collect parts in a list and .join() them before returning.

I want to delete useless header to get lower latency. Is it possible delete these useless headers? I want to remove 'Set-Cookie: header first. Is there any prepared request header options related to cookie? If it isn't possible, second possible is using http2-ALPN? help me...
...ANSWER
Answered 2022-Mar-19 at 14:40Is it possible delete ....
A client cannot remove headers the server is sending - unless the server is specifically programmed to let the client do this by instrumenting the HTTP request. Usually this is not the case.
... these useless headers?
These headers actually have a defined meaning, i.e. they are not useless.
... to get lower latency
Omitting these headers will likely not improve latency at all. Latency primarily depends on the round trip time and on the number of data exchanges were one side needs to wait for the other to continue. Costly for latency are TCP handshake and TLS handshake, but not really if the server sends a bit more data in the HTTP response.

QUESTION
There are so many ways to define colour scales within ggplot2. After just loading ggplot2 I count 22 functions beginging with scale_color_* (or scale_colour_*) and same number beginging with scale_fill_*. Is it possible to briefly name the purpose of the functions below? Particularly I struggle with the differences of some of the functions and when to use them.
- scale_*_binned()
- scale_*_brewer()
- scale_*_continuous()
- scale_*_date()
- scale_*_datetime()
- scale_*_discrete()
- scale_*_distiller()
- scale_*_fermenter()
- scale_*_gradient()
- scale_*_gradient2()
- scale_*_gradientn()
- scale_*_grey()
- scale_*_hue()
- scale_*_identity()
- scale_*_manual()
- scale_*_ordinal()
- scale_*_steps()
- scale_*_steps2()
- scale_*_stepsn()
- scale_*_viridis_b()
- scale_*_viridis_c()
- scale_*_viridis_d()
What I tried
I've tried to make some research on the web but the more I read the more I get onfused. To drop some random example: "The default scale for continuous fill scales is scale_fill_continuous() which in turn defaults to scale_fill_gradient()". I do not get what the difference of both functions is. Again, this is just an example. Same is true for scale_color_binned() and scale_color_discrete() where I can not name the difference. And in case of scale_color_date() and scale_color_datetime() the destription says "scale_*_gradient creates a two colour gradient (low-high), scale_*_gradient2 creates a diverging colour gradient (low-mid-high), scale_*_gradientn creates a n-colour gradient." which is nice to know but how is this related to scale_color_date() and scale_color_datetime()? Looking for those functions on the web does not give me very informative sources either. Reading on this topic gets also chaotic because there are tons of color palettes in different packages which are sequential/ diverging/ qualitative plus one can set same color in different ways, i.e. by color name, rgb, number, hex code or palette name. In part this is not directly related to the question about the 2*22 functions but in some cases it is because providing a "wrong" palette results in an error (e.g. the error"Continuous value supplied to discrete scale).
Why I ask this
I need to do many plots for my work and I am supposed to provide some function that returns all kind of plots. The plots are supposed to have similiar layout so that they fit well together. One aspect I need to consider here is that the colour scales of the plots go well together. See here for example, where so many different kind of plots have same colour scale. I was hoping I could use some general function which provides a colour palette to any data, regardless of whether the data is continuous or categorical, whether it is a fill or col easthetic. But since this is not how colour scales are defined in ggplot2 I need to understand what all those functions are good for.
ANSWER
Answered 2022-Feb-01 at 18:14This is a good question... and I would have hoped there would be a practical guide somewhere. One could question if SO would be a good place to ask this question, but regardless, here's my attempt to summarize the various scale_color_*() and scale_fill_*() functions built into ggplot2. Here, we'll describe the range of functions using scale_color_*(); however, the same general rules will apply for scale_fill_*() functions.
There are 22 functions in all, but happily we can group them intelligently based on practical usage scenarios. There are three key criteria that can be used to define practically how to use each of the scale_color_*() functions:
Nature of the mapping data. Is the data mapped to the color aesthetic discrete or continuous? CONTINUOUS data is something that can be explained via real numbers: time, temperature, lengths - these are all continuous because even if your observations are
1and2, there can exist something that would have a theoretical value of1.5. DISCRETE data is just the opposite: you cannot express this data via real numbers. Take, for example, if your observations were:"Model A"and"Model B". There is no obvious way to express something in-between those two. As such, you can only represent these as single colors or numbers.The Colorspace. The color palette used to draw onto the plot. By default,
ggplot2uses (I believe) a color palette based on evenly-spaced hue values. There are other functions built into the library that use either Brewer palettes or Viridis colorspaces.The level of Specification. Generally, once you have defined if the scale function is continuous and in what colorspace, you have variation on the level of control or specification the user will need or can specify. A good example of this is the functions:
*_continuous(),*_gradient(),*_gradient2(), and*_gradientn().
We can start off with continuous scales. These functions are all used when applied to observations that are continuous variables (see above). The functions here can further be defined if they are either binned or not binned. "Binning" is just a way of grouping ranges of a continuous variable to all be assigned to a particular color. You'll notice the effect of "binning" is to change the legend keys from a "colorbar" to a "steps" legend.
The continuous example (colorbar legend):
