Today I want to talk about an issue I was having with UDP sockets in Go, and how I learned more about my program by making use of two tools that ship with Mac OS X called dtruss, and DTrace.
Did you know you can inspect your node application's memory without instrumenting your code? It's possible using a tool called mdb_v8. With mdb_v8 we can produce a core dump of a running node process, and then later inspect the memory at the time the core dump was generated. This leads to some powerful postmortem debugging capabilities.
Lately I've been doing more work in the Go programming language. Today I thought I would share three "gotchas" that caught me off guard, or otherwise produced results that I would not have expected in my work with Go.
