Ars Technica writes that "At SourceFoundry.org this week, programmer Chris Simpkins debuted the 2.0 version of Hack , an open-source typeface designed specifically for use in source code ." The revamped font is "characterized by a large x-height, wide aperture, and low contrast design in order to be 'highly legible' at common coding text sizes," and the font specimen shows how legible it is right down to downright tiny sizes, though Simpkins says the sweet spot is between 8 and 12 pixels.
