The blog has other interesting articles on (Emacs) Lisp, Scheme, git...

This post is a survey of technical and community issues connected to Plan 9 root file servers. The author is not a member of any Plan 9 tribe save Grid.

"ma" is a minimalistic clone of the acme[1] editor used in Plan 9, and is written in Tcl/Tk. It has been tested with Tcl/Tk 8.5, mostly
under Linux. "ma" has successfully been run on Mac OS X with XQuartz, but needs a tiling window manager to be used in a satisfactory way.

Description of an interesting operating system (not implemented yet) based on ideas from QNX and Plan 9.

Apart from the Scheme compiler Chicken

 MA, a minimalistic variant of the Acme editor, written in Tcl/Tk.

Beginning with the Eighth Edition, ed(1) had the following command.
This is from the Plan 9 ed man page.

         (.,.)b[+-][pagesize][pln]
              Browse.  Print a `page', normally 20 lines.  The
              optional `+' (default) or `-' specifies whether the
              next or previous page is to be printed.  The optional
              pagesize is the number of lines in a page.  The
              optional `p', `n', or `l' causes printing in the speci-
              fied format, initially `p'.  Pagesize and format are
              remembered between `b' commands.  Dot is left at the
              last line displayed.
