QUESTION
I am still somewhat of a novice to React with much to learn. At the moment I am trying to make a page displaying lightsabers and hilts from Star Wars by clicking a button to show the ones you want. I am doing this by using State, which by the amount of states I currently have seems like the wrong way of doing it.
Here's how I'm doing it: I set a State and put an onClick event that sets the chosen hilt/color to true and the rest to false whilst also rendering information of said hilt/color. It looks like this:

Trying to analyze some text data and search for keywords. I have the text data in a pandas dataframe, and I have the keywords in another dataframe. What will be the most efficient method to search the text data dataframe for each item in the keyword dataframe? I'm trying to avoid looping if possible, since I know that can get pretty horrible performance. I thought about writing a function which I could then use dataframe.apply on the source dataframe, but I can't figure out a way to get around having to loop through the second dataframe and look for each keyword in my source...
I've included an example below of the source data setup, as well as a mockup of what my resultant dataframe should look like. Score would be how many of the keywords are in the text for that row. Thanks in advance!!

QUESTION
I'm working on a prototype for a lightsaber that changes the pitch and volume of its hum sound as it moves. The current solution only changes the volume (easy), and it doesn't sound realistic enough. I know I need to use .wav or .aiff (not lossy like mp3) to accomplish this. Ideally I'm looking for a lightweight solution, as I plan on running the final iteration of this on an Arduino Nano extra. So, the question is, how can I alter the speed a .wav or .aiff is read/output (thus changing the pitch of the sound)? Regardless of computing power, does anyone know ANY approaches that could accomplish this in real time?
...ANSWER
Answered 2021-May-11 at 22:06Hmm... I'm not entirely sure how this would work. It's my understanding that .wav and .aiff files are raw audio (maybe that's why you say you need to use them) I did find this answer Python change pitch of wav file but it uses python, which won't work for your Arduino, but its possible you could apply this technique using C++. Maybe someone else who knows more about this could take a look at that and explain how it might be done in C++

I need to match documents that have an array field of subdocuments where at least one of those subdocuments is missing a field. In this example (obfuscated form of the actual thing), I'm looking for a jedi that has at least one lightsaber which is not lost. The problem is that lost_date only exists in the subdocument when it's value is set.
Given the index:

Answered 2021-Jan-04 at 15:42I believe you did everything right except for a couple of things:
- A collection of objects must be mapped as
nestedtype for them to work - In order to query them, you need to wrap things in a
nestedquery, surprisingly.
This is the correct(simplified) mapping:

I created a very simple story generator with Python based on this comic strip: https://xkcd.com/2243/
Each time that I run the script, it generates a new random story, however, if the user chooses to run it again by writing "y", the story generated is always the same. What am I doing wrong?
This is the code:

Answered 2020-Aug-12 at 10:14The variables are never updated, just computed at the start of the program.
Put all the random.choice lines in the rsg function and you will be good !
QUESTION
I have a snowflake database table currently defined like
...ANSWER
Answered 2020-May-06 at 07:52Unfortunately this is not going to work, as (per documentation) when setting the TYPE for a column in alter, the specified type (i.e. type) must be NUMBER or a text data type (VARCHAR, STRING, TEXT, etc.) and there are some limitations on how this can be used too - thing is Snowflake does not automatically know how to make data conversion so the options to change data types are not full.
maybe try the more complex path of adding a new column with desired data type, copying the data and removing old column?

Just started with Vapor 3 along with a MySQL database and I am having hard time figuring out the Relations part.
I have created 2 models so far: Movie and Actor.
A Movie can have many Actors and an Actor can have many Movies.

ANSWER
Answered 2018-Jul-23 at 09:09So the underlying issue here is that computed properties aren't provided in a Codable response. What you need to do is define a new type MoviesWithActors and populate that and return that. Or provide a second endpoint, something like /movies/1/actors/ that gets all the actors for a particular movie. That fits better with REST but it depends on your use case, as you may not want the extra requests etc

I'm remaking flappy bird in pygame but with a Star Wars theme. I've completed the art and general formatting of the game, but now I need to tweak the specifics. I've been switching numbers around to try to get the lightsabers to fully reach the top and bottom of the screen because at the moment there are sometimes gaps that aren't the intended space to pass through.
