Very glad to see more “low x height” monospace fonts (x height is the height of lowercase letters relative to capital letters; I haven’t checked to be sure but my eyes tell me this is on the lower side). Source Code Pro has been my go-to for a very long time, and it has always bothered me that Apple opted for higher x-heights in their San Francisco re-design of Helvetica (which already has a high x height to begin with).
It’s interesting that they had high-powered readability consultation and a lot of real-world tests with visually impaired developers and still ended up with low x heights. I had heard higher x heights were preferred for readability.
