+
+In contrast to my [[course website]] project, which is mostly about
+constructing a framework for automatically compiling and installing
+[[LaTeX]] problem sets, [Prof. Vallières'][MV] [Parallel
+Computing][phys405] course is basically an online textbook with a
+large amount of example software.  In order to balance between to
+Prof. Vallières' original and my own aesthetic, I rolled a new
+solution from scratch.  See [my version of his Fall 2010 page][f10]
+for a live example.
+
+Differences from my course website project:
+
+* No PHP, since there is no dynamic content that cannot be handled
+  with [[SSI]].
+* Less installation machinery.  Only a few build/cleanup scripts to
+  avoid versioning really tedious bits.  The repository is designed to
+  be dropped into your `~/public_html/` whole, while the course
+  website project is designed to `rsync` the built components up as
+  they go live.
+* Less LaTeX, more XHTML.  It's easier to edit XHTML than it is to
+  exit and compile LaTeX, and PDFs are large and annoying.  As a
+  computing class, there are fewer graphics than there are in an
+  intro-physics class, so the extra power of LaTeX is not as useful.
