Meta post I've decided to make. I enjoyed the unixporn subreddit a lot when I used reddit more. I enjoy customizing my linux de as much as the next nerd.
But you definitely shouldn't use racist slang to refer to the process.
To be clear, I didn't know the origin of the term 'ricing' until fairly recently. I was chattimg with my friend and used it to describe my de setup. They informed me that apparently it's from car customization, and is a pejorative against generally asian men who customize their car to look like a racecar.
After learning this I was sad to realize just how engrained it is in linux de customization culture. I personally have stopped using the term, and I would ask everyone here stop as well.
As someone that was very into cars (still kind of am but not nearly so much) and tuner culture. Yes, "rice" in the context of customizing a machine to your specific performance needs has always had racist baggage and likely always will. This is a weird hill to die on bud, and it makes you look very sus.
