That looks like a monospaced version of Bitstream’s Prima Serif/Vera Serif/DejaVu Serif, but if it is, I can’t find it anywhere.

Given that these fonts are open source, it’s possible that this is a monospaced variant custom-made by the user/designer.

Edit: Found it! It’s Verily Serif Mono, based on Vera Serif.

Close enough, I guess. :)

Excellent find, Thanks!
