A quick suggestion for the author based on the "dude I can't debug anything on OS X" line - take a look at DTrace, which is shipped with MacOS (albeit an old version). Compared with strace on Linux it is like night and day.

  can we have all man pages converted into "zine" pages, as Julia Evans does for strace here :-) http://jvns.ca/strace-zine-unfolded.pdf http://jvns.ca/strace-zine-unfolded.pdf

  Apparently so! I didn't read the author's site beyond the original article.

Good advice, on Windows it's really a nightmare though.. Investigating why the OS seems to 'freeze' a process for 10s once in a while (threading issue?) is really mysterious..

DTrace is closer to something like LTTng than to strace, though.

  dtrace is an "everything tracer", so it's a superset of strace… and a ton of other stuff.

    In other words, you can whip up strace in a few lines with DTrace.

      DTrace comes with a syscall tracer called 'dtruss'. One serious problem - it has to run as root.

    sounds kinda like SystemTap?
    - masklinn 11y ago
      SystemTap is dtrace for linux, at least in intent (implementation and details differ)

Unfortunately, dtrace does not work any more on El Capitan by default.
