The Son of the Return of Yet Another Posting about Programming Fonts
Like almost everybody doing stuff with computers, I played around with various monospaced fonts. Since the old days of pixilated characters on green-glowing 25×80 terminals a lot of effort has been put into usable fonts for programmers.
This went so far that hackers joined the ranks of font designers, for example Raph Levien with his Inconsolata and his other fonts, not to forget his library Spiro which is integrated in the open source fontdesign tool fontforge.
Recently I stumbled over — and subsequently bought — Operator (Mono), a typewriter-inspired font by the famous type designers at Hoefler & Co. It's the only programmer's font with its own documentary AFAIK.
