I built software systems for large astronomical instrumentation at Smithsonian Astrophysical Observatory for 27 years. I've been at Facebook since 2014.

JBR in discussions

  Tcl's detractors like to harsh on the Tcl mantra "every thing is a string".  I
  like consider the corollary of this : Code is data is code.  Tcl is not so
  much a programming language in the traditional sense. It is a set of
  primitives to pass data and control execution scope.
