Walk though of one approach to creating/customizing an annoying/streaming application for newsfeeds[0] using python.
Each article/groups of articles can be placed in it's own pop-up window[1] (perhaps with maximum number of open windows, window lifefime timer[2], and/or article time/date range to avoid opening up 30,000 HN news article windows).
Near endless interruptions can be created by converting text to audio with audio output directly to speaker headphones[3].
Bundle it all together as stand alone application [4] & remove python in order to have more resources for open HN article windows. :-)
