Dark on Light or Light on Dark? [duplicate]

For a very technical site documenting code, sharing code snippets, and documentation, I have been told that using dark fonts on light backgrounds is recommended for people being able to read the information clearly as possible.

While, for my eyes and designing skills, dark backgrounds and light text works way better for me. A few clients have said that that does not work at all for the type of site which I have created.

Which would work better for a technical site: dark backgrounds with light colour fonts or light backgrounds with dark fonts?
