Narrow fixed-width fonts for coding

I code a lot, and so I like having good monospaced / fixed-width fonts for doing so. Lately I think I prefer narrow coding fonts because they give me more characters per line that I can see at once. So I did a web dive to find some good narrow coding fonts online. Here are some I liked. I’m currently using M+1M as my main code font in Eclipse, Qt Creator, and other IDEs.
