10 Techies in the Shadows - Bryan Cantrill, creator of DTrace, Sun Microsystems
DTrace is a dynamic tracing framework for Solaris, FreeBSD and Mac OS X, and is likely headed for Linux and other operating systems in the future. It allows people to look inside running software and work out problems while the program executes. What this means is that DTrace allows enterprise software to be far better tuned and debugged because both system administrators and developers can inspect the running code. DTrace could be a game changer for enterprise software, once it gets onto more platforms.
Some of the people on this list are little-known co-founders playing second banana to more famous names. Others have broken new ground or developed much-heralded technologies without winning much fame for themselves. You should know them, and, more importantly, you should know what they do.
