How to find out what type of a Mat object is with Mat::type() in OpenCV
...";
r += (chans+'0');
return r;
}

Sass combining parent using ampersand (&) with type selectors

#id > .element {
@at-root #{selector-unify(&, div)} {
color: blue;
}
}
Will compile to:
#id > ...

If you're looking for a way to put your functions/methods in a namespace (i.e. not global), you could consider using TypeScript's mod...
How to get HTML 5 input type=“date” working in Firefox and/or IE 10
...nd it odd that input type="date" is still not supported in Firefox after all of this time. In fact, I don't think they added in much (if any) of the HTML 5 new types on an input element. Not surprised that it is not supported in IE10. So, my question is...
