6 Debian booth at SfN2010 in San Diego
7 ====================================

12 During November 13-17, 2010 the NeuroDebian team ran its first Debian booth at the
13 annual meeting of the `Society for Neuroscience`_ (SfN2010_) in San
14 Diego, USA. We presented the upcoming release Debian 6.0 Squeeze and
15 demonstrated its utility as a robust and versatile research environment for
16 neuroscience. Booth visitors had the opportunity to meet with developers
17 of neuroscience research software, and to get information on available software
18 and recommendations for deployment strategies in research laboratories.

22 The `annual meeting`_ of the Society for Neuroscience is one of the largest
23 neuroscience conferences in the world, with over 30,000 attendees. Researchers,
24 clinicians, and leading experts discuss the latest findings about the brain,
25 nervous system, and related disorders.
31 `Don Armstrong`_ kindly provided us with Debian banners to decorate the
32 booth and some Debian T-shirts to give away. Moreover, we were equipped with
33 laptops running Debian squeeze and sid, as well as two additional laptops each
34 running a Debian squeeze virtual machine on top of Mac OS X and Windows,
35 respectively (CDs with the VM image were also available for visitors to take
36 home). To demonstrate Debian's versatility, we had a complete Debian
37 archive mirror that was used to show the full selection of available software
38 and the simplicity of installation and upgrade procedures. The mirror
39 was provided from an external harddrive by a commodity router box
40 running the Debian-based DebWrt_ distribution.
41 All machines were connected to our own local wired network to avoid problems
42 with conference center's free wireless network (poor at best). Finally, we had
43 several hundred `tri-fold flyers`_ with general Debian facts on one side, and
44 NeuroDebian facts on the other (`sources are available`_).

50 Halchenko and Swaroop Guntupali.
56 The booth was well attended on all days of the conference. Many people were
57 somewhat surprised, but also pleased to see Debian represented. The visitors
58 comprised the whole range from long-term Debian users to people who were not
59 aware of an operating system other than Windows and Mac OS.
61 A number of visitors were involved in free software development -- at various
62 levels. We talked to a Debian ftpmaster, a Gentoo developer, various developers
63 of neuroscience-related software that is already integrated in Debian and many
64 more whose work still needs to be packaged. We were visited by representatives of
65 companies looking for support to get their open-source products into Debian.
66 The vast majority, however, were scientists looking for a better research
67 platform for their labs. That included the struggling Phd-student, as well as
68 lab heads sharing their experience managing a computing infrastructure for
69 neuroscience research.
71 The Debian booth also served as a platform for upstream developers to meet with
72 Debian users of their software.

78 Debian-based systems are the preferred Linux environment
79 --------------------------------------------------------
81 The overwhelming majority of visitors running some Linux flavor used a
82 Debian-based operating system -- including Debian_ itself, Ubuntu_ and
83 sidux/apttosid_. Especially people using Python for research purposes seem to
84 prefer the comprehensive support of Python modules in Debian, whereas e.g. R_
85 users are more uniformly distributed across GNU/Linux distributions. This
86 assessment is, of course, biased by the fact that Debian was the only
87 distribution that was present at this conference.
89 In general, we had the impression that Linux users employ a larger variety of
90 tools in their research activities, whereas users of proprietary operating
91 systems tended to limit themselves to a more restricted set, or use an
92 intermediate computing platform, such as Matlab.

96 During the conference's poster session we explained the Debian system and
97 community processes to many interested visitors (`download the poster`_).
103 While there was a large variety of topics that were brought up by visitors there
104 were some common patterns.
108 For a Debian developer it may be surprising, but many people still do not
109 know that Debian exists -- even despite the fact that Debian is often a
110 perfect match for their particular requirements. People who got introduced to
111 Debian at the booth often couldn't believe what they were hearing or
112 seeing: so much software, runs on any hardware, all for free.
114 We believe it would be very beneficial for Debian to reach out beyond the IT
115 sector and present itself in all fields of applications that it already
120 Apparently it is still a largely unknown fact that Ubuntu is based on Debian.
124 There was a significant demand for (customized) Live-CDs. On one hand, people
125 were asking for a way to quickly try out Debian (and we believe that this
126 doesn't necessarily have to be a live-cd). On the other hand, for example,
127 teachers were asking for means to temporarily deploy Debian on, e.g.
128 university computer pool machines and use Debian-packaged software for
129 teaching courses (e.g. on brain-imaging data analysis).
131 Electrophysiology tools
133 Of all subfields of neuroscience, electrophysiology researchers expressed the
134 greatest demand for better tools in Debian -- or basically at least some
135 specialized tools at all. Moreover, many research projects relying
136 on FOSS solutions in electrophysiology already use Debian-based
137 systems to accomplish the mission; they just rely on manual (from sources)
138 deployment of the necessary tools. We started a `new Debian Science Blend task`_ to
139 collect information about existing relevant software and to eventually package it.
141 Realtime capabilities
143 Apparently, numerous research groups utilize Debian-based equipment to perform
144 various flavors of real-time data acquisition and processing. They expressed
145 their demand for real-time capabilities of (some) Debian kernel images.
149 Cloud-computing seems to be an increasingly interesting topic for neuroscience
150 data analysis. We got the impression that there is a tendency to look for
151 alternatives to Matlab to be able to run analyses in the cloud cheaper (or at
152 all). We pointed people to ongoing efforts in Debian to enable Debian-based
153 cloud computing (see e.g. the `Debian wiki`_).
159 Throughout the conference many people stopped by to express their gratitude to
160 Debian for developing their operating system of choice. We want to affirm this
161 and relay it to the larger Debian community. Thanks for Debian.
