Innovations from multiple directions have been proposed to improve software reliability. Unfortunately, many of the innovations are not fully exploited by programmers. To bridge the gap, this paper proposes a new approach to "listen" to thousands of programmers: studying their programming comments. Since comments express programmers' assumptions and intentions, comments can reveal programmers' needs, which can provide guidance (1) for language/tool designers on where they should develop new techniques or enhance the usability of existing ones, and (2) for programmers on what problems are most pervasive and important so that they should take initiatives to adopt some existing tools or language extensions. We studied 1050 comments randomly sampled from the latest versions of Linux, FreeBSD, and OpenSolaris. We found that 52.6% of these comments could be leveraged by existing or to-be-proposed tools for improving reliability. Our findings include: (1) many comments de...
