+<p><a href="gopher://bitreich.org">Bitreich</a> is an initiative
+to promote minimal and perfect programming and system design practice.
+In a nutshell, the philosophy favors simple and well-designed
+solutions (e.g. C, POSIX, Unix) over convoluted and hyped
+software-development tools (cloud deployment, docker, systemd,
+autotools, and so on). The bitreich information site uses the
+WWW-precursor protocol <a

+protocol, and you can now access my website through <a

+programs and libraries. My client of choice is <a

+
+<p>I presented
+my thougts on scientific software development during the <a

+I am fascinated by the simplicity and efficiency of the gopher

+efficiency.
