I'm working on a game with a software renderer to get the most accurate PS1 look. As I was doing research on how the PS1 graphics/rendering system worked, reason for the wobbly vertices etc, I came across some documentation regarding the way they did their divide. Here is the link to it: http://p...

I got the idea from capsterx's answer to this question.
As it turns out, it works fine, but it uses much more memory and compile time then the standard

Of course it avoids all the hassles of the original: Having to deal with (and extend) the given limits ...

I attempted to recreate the Polybius square, also called the Polybius checkerboard, which was used in Ancient Greece for cryptography. Since it is an uncommon cipher, it is nowhere on Code Review.

my first question here on Code Review is about my first working PHP class.
Could be this code considered as a real class in the way of thinking or is it just procedural code put into a class?
Would you improve it in any way?
Do you have any suggestion to write it better?
Thanks

So there's not much here to "normalize" the database (really only the OrderItems class and maybe the Table Meta class as well) but I'm relatively happy with it.
My only concern is the repeated "Name" property in many of the tables but since it doesn't appear in all tables, it doesn't make sense ...

I wrote a function which takes in input a list of strings that is splitted by comma. Then each generated string is trimmed.
Example:

OUTPUT: Cat Dog Snake
In particular, I'm interested in removing parenthesis and commas.
This is the code I wrote, but I think i...

How would I use a sound clip to change the opacity of an image. The idea would be as the sound increases or decreases so would the opacity of the image?
This might seem like a trivial question but, if I have a regex like this:
[a]{2}[b]*[c]?
is it better to write it like this?
a{2}b*c?
For one I believe the first is more readable but im not sure if this is good practice.

I'm not sure how you got the original list-within-a-list input, but have you looked into Java Streams? Here's a tutorial that may help.
