[NYC*BUG Announcements]

October 10, Wednesday, 1845
OPNsense: true(1) and false(1), The Classical Code Reading Group of
Stockholm, NYC*BUG Mix Tape Edition
Read by: George Brocklehurst
Stone Creek Bar & Lounge: 140 E 27th St
Notice: this will be a fun departure from our normal format

A different sort of event, cloned (with blessing) from The Classical
Code Reading Group of Stockholm (recently in NYC).

This is a reading group for code. Our focus will be the classics and
tools we use every day. The inspiration is the shared metaphors and
expressions we have in natural language due to common books (e.g.
Hitchhiker's Guide to the Galaxy, Romeo and Juliet) and movies (e.g.
Hackers, A Christmas Carol).

True(1) and false(1):

This meetup will concentrate on simple and common commands: true and
false. We will start with the OpenBSD true program and compare it to
FreeBSD's, Solaris', GNU bash's, and GNU's. They all have different
complexity, and some even have different features, which should provide
for an interesting discussion.

Feel free to read the source code ahead of time and reflect on some of
the talking points or come up with additional ones.

While reading the code consider the following discussion points in
addition to any you think of: What is the code boilerplate and why is it
there? This is a small program; how did the different implementations
demonstrate this? Why does this program exist? What shortcuts did they
take and how do those make it easier to read?

For those who don't yet have five variants of true.c on your hard disk,
you can find them online:

OpenBSD:
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/true/true.sh?rev=1.2&content-type=text/x-cvsweb-markup
http://cvsweb.openbsd.org/cgi-bin/cvsweb/src/usr.bin/false/false.sh?rev=1.2&content-type=text/x-cvsweb-markup

FreeBSD:
http://svnweb.freebsd.org/base/head/usr.bin/true/true.c?revision=216370&view=markup
http://svnweb.freebsd.org/base/head/usr.bin/false/false.c?revision=216370&view=markup

Solaris:
https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/true/true.c
https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/false/false.c

GNU Bash (builtin):
https://raw.githubusercontent.com/bminor/bash/master/examples/loadables/truefalse.c

GNU Coreutils:
http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/true.c
http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/false.c

This should all take about three hours.


Speaker Bio
George Brocklehurst (of the original Stockholm meetup) will be leading
the reading.

Special thanks to Mike Burns and George Brocklehurst for bringing this
excellent event to NYC!
