Mainly because it has attracted reduced-high-quality or spam answers that had to be eliminated, publishing an answer now demands ten status on This website (the Affiliation reward won't rely).

Any programmer should really know the basic principles of the foundation libraries of the project becoming labored on, and utilize them properly.
