Hi everyone --
We hope you can join us for CDBUG. Today! May 12 at 6:45PM at INOC, 80
State St., Albany.
Ian Sutton will be presenting on "SystemBSD: custom DBus daemons
emulating systemd behavior for OpenBSD."
Upcoming CDBUG events:
June 9-14: BSDCan 2015. I will be giving co-giving a talk about NYC*BUG
June 17: OpenBSD developer Ingo Schwarze (schwarze@) will be giving a
talk on "mandoc: from scratch to the standard BSD documentation toolkit
in 6 years"
Both the May and June abstracts and bios are posted below.
May, Ian Sutton on "SystemBSD: custom DBus daemons emulating systemd
behavior for OpenBSD":
This talk will concern my work with the OpenBSD Foundation in the summer
of 2014 involving writing four DBus daemons which emulate the behavior
of some systemd interfaces, mentored by Landry Breuil (landry@) and
Antoine Jacoutot (ajacoutot@). It will cover the rationale for this
project idea (GNOME desktop support, etc.) as well as the technical
details and current status of the project. Additionally, I will discuss
my experience with the project as well as some thoughts and criticisms
of systemd in the context of Linux's init/job control vs. BSD's.
Finally, I'll end by discussing what I have found as a relatively new
*BSD user switching from Linux and why I am happy with such a choice.
Ian Sutton is a senior undergraduate computer engineering student at
Syracuse University's College of Engineering and Computer Science. He
has been inseparable from computers since he learned to read, and
starting using Linux around 2006 until he mostly switched to OpenBSD in
2013. He lives in Houston, TX, where he was born and raised.
June, Ingo Schwarze (schwarze@) on "mandoc: from scratch to the standard
BSD documentation toolkit in 6 years":
When <a href="http://kristaps.bsd.lv/">Kristaps Dzonsons</a> set out to
write <a href="http://mdocml.bsd.lv/">mandoc</a> in the fall of 2008,
all he wanted was a nicer HTML representation of manual pages on his
private website. Today, mandoc is the standard manual page formatter in
OpenBSD, FreeBSD, NetBSD, DragonFly, illumos, and Void Linux, and
OpenBSD also uses it as the manual page viewer man(1), as the manual
page search tool apropos(1)/makewhatis(8), and as man.cgi(8) to search
and display manual pages on the web. It now produces ASCII, UTF-8,
HTML5, MathML, PostScript, PDF, and man(7) output. Given that manual
page toolkits existed for almost four decades before Kristaps even
started, how could such an overfulfillment of expectations possibly
happen, and what lessons were learnt in the process?
Topics of this meeting include:
- importance of and requirements for software documentation
- history of roff/man/mdoc, and why they remain the best doc tools
- features of mandoc, both seasoned and new ones
- mandoc development and system integration, or how to lead a software
package to success
- mandoc adoption in various operating systems and possible future
The talk is designed as a best-of selection of content shown at BSDCan
2011, 2014 and 2015 and EuroBSDCon 2014.
After the presentation, you are welcome to optionally stay for a
hands-on workshop, so be sure to bring your notebook. You might wish to
hunt for markup bugs in operating system manuals, or you might wish to
work on format conversions from legacy formats to mdoc(7), and if you
already have some experience, there are more ideas, see for example
pages 40-43 of
In any case, there is a chance to do some work that results in your
first commit into your favourite operating system - that did happen at a
similar workshop held at EuroBSDCon 2014 in Sofia/Bulgaria...
Ingo Schwarze is the current maintainer of the mandoc(1) documentation
toolbox developed by Kristaps Dzonsons. He also maintains the OpenBSD
groff(1) port and has contributed to various parts of the OpenBSD
userland, for example the Perl rewrite of the security(8) script, as
well as smaller contributions to the rc.d(8)/rcctl(8) framework, the
yp(8) subsystem, the C library, and various other programs.
After studying in Siegen (supervisor: Prof. Martin Holder), Ingo
Schwarze worked in experimental and theoretical high energy physics at
CERN (NA48) and in Karlsruhe. Having used various flavours of UNIX and
Linux in the nineties, he settled on OpenBSD as his server and desktop
operating system of choice in 2000 and joined the project as a developer
in the spring of 2009. As a day job, he maintained the central
configuration daemon and the MiddleWare of the Astaro Security Gateway
(now called Sophos UTM) for six years.
