Do you need to close meta and link tags in HTML?

A tag must always be closed by the tag close symbol > (if we ignore certain SGML rules that nominally apply in non-XHTML HTML but were never implemented in browsers).
What you mean to ask is whether the elements need to be closed by end tags. The answer is that non-XHTML HTML (i...
os.walk without digging into directories below
...d root, dirs, files
num_sep_this = root.count(os.path.sep)

Pure virtual function with implementation

class B : public A {

Difference between maven scope compile and provided for JAR packaging
What is the difference between the maven scope compile and provided when artifact is built as a JAR? If it was WAR, I'd understand - the artifact would be included or not in WEB-INF/lib. But in case of a JAR it doesn't matter - dependencies aren't included. They have to be on classpath when thei...
