Speaking of cross platform UIs, on iOS the page hijacks scrolling so you can't scroll past the wx widget code segment.
I tried flicking the page right above the code fragment, but it turns out the scroll hijacking disables iOS's native inertial scrolling, so there's no way for me to read the rest of the article until I get back to my desktop.
I don't see the need for down-votes here: clearly many authors (in absolute terms, if not relative terms) tease their viewers with 30 minutes of reading, only to frustrate them by making the rest of the page inadvertently unreachable. I would think of these kinds of comments as a courtesy to the author.
