Of course, 98% or so of the code will be the same amongst the different systems, and it makes sense to keep the code base intact. My question is - what would be the prefer...
Hello, I have 2 matrices and I need to multiply them and then print the results of each cell. As soon as one cell is ready I need to print it, but for example I need to print the [0][0] cell before cell [2][0] even if the result of [2][0] is ready first. So I need to print it by order. So my idea is to make the printer thread wait until...

Is anyone aware of tutorials for walking ANTLR-generated ASTs in C#? The closest I was able to find is this, but it's not terribly helpful. My goal is to walk through trees that I'm generating based on a domain-specific language that I'm working on, and to use the trees to output generated C# code. A Java-based tutorial would be helpfu...
