lightsaber | Compile time dependency injection framework for JVM | Compiler library

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:

I am learning HOF at the moment:

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!!

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?

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:

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:

I have a snowflake database table currently defined like

I am trying to find an efficient way of changing the length of an array and the elements within the array. For example, if I have
