I made a function which checks if a word is the opposite of each other (ex: word and drow) and then realized that with minor changes it could also be used to detect if a word is palindrome. They both return bools, false means they aren't opposite/it isn't palindrome, true means they are/it is.

I one of my tools I use the user can define grouping for a DataTable. The criteria are known only at run-time. To achieve this I use a Dictionary<string, object> with a custom dictionary comparer that the GroupBy extension cosumes so that I can aggregate the groups. This works pretty well but I w...
I am practising my coding skills on interviewbit. I got one question about preorder (or tree). This is what I did first:

Recently, I've been transferring some of my old vinyl records to MP3 files. One of the things I did to make some progress was to automate things, so I initially set things up so that it would record each album to a single MP3 file. Now I've gotten to the step where I want to separate those out ...
I'm creating a minecraft clone (for practice), in scala, using largely functional programming. When a chunk doesn't have a mesh loaded into VRAM, it create a Future for the vertex and index arrays, and gives it to a low priority ExecutionContext (so as not to freeze the main game loop). The rende...

I am trying to programm the Abelian sandpile model in VisualBasic.
However, with large amounts of sand the calculation takes a very long time, and I wonder: Is there a possibility of speeding the code up?
To be fair, I am mostly self-taught in VB, so my code is likely to be ugly.
