[applause]

00:32:16.120 --> 00:32:21.720
Thank you very much.
Next step is Stefan Weil

00:32:22.380 --> 00:32:26.480
talking about PalMA and Debian
in Mannheim.

00:32:58.960 --> 00:33:02.400
Thanks. Hello and welcome everybody.
My name is Stefan Weil,

00:33:02.420 --> 00:33:02.670
and I am going to tell you about a 
Debian based freeware development

00:33:07.281 --> 00:33:09.181
at Mannheim University Library.

00:33:09.181 --> 00:33:14.780
Large parts of our library are located in
Mannheim Palace,

00:33:14.780 --> 00:33:18.521
and there we transformed a former reading
room into a modern learning center

00:33:18.521 --> 00:33:21.740
which opened in spring last year.

00:33:21.740 --> 00:33:26.880
This learning center provides different
kinds of places for working in groups,

00:33:26.880 --> 00:33:31.160
and most of them have a large monitor
where the group members can share

00:33:31.160 --> 00:33:34.621
their presentations and any documents.

00:33:34.621 --> 00:33:41.020
Students bring their own devices -
laptops, smartphones or tablet computers.

00:33:41.020 --> 00:33:45.381
They should be able to use the team
monitors by wireless LAN,

00:33:45.381 --> 00:33:48.260
without any cables.

00:33:48.260 --> 00:33:51.400
Existing solutions did not match
our requirements,

00:33:51.400 --> 00:34:01.120
so we wrapped existing technology in a new
web application which we called PalMA.

00:34:01.120 --> 00:34:06.660
The team monitor shows some short
instructions how to use PalMA

00:34:06.660 --> 00:34:13.700
(which is an abbreviation of
"Present and learn in Mannheim").

00:34:13.700 --> 00:34:18.660
Other libraries which adapted PalMA later
have chosen a different name like

00:34:18.660 --> 00:34:26.400
SPrinT (which stands for
"Study and present in teams").

00:34:26.400 --> 00:34:32.400
As soon as a user connects to the
PalMA URL, he or she gets a web interface

00:34:32.400 --> 00:34:37.540
which controls all aspects of PalMA:

00:34:37.540 --> 00:34:41.240
This is what the user sees in the browser,

00:34:41.240 --> 00:34:45.141
and in the upper right corner, you
see the connected group members,

00:34:45.141 --> 00:34:53.840
then the user can show web pages
in the left lower corner

00:34:53.840 --> 00:34:56.500
on the team monitor.

00:34:56.500 --> 00:35:01.560
He can upload different kinds of files
(also in the left corner) for displaying

00:35:01.560 --> 00:35:04.360
on the team monitor, or he can use

00:35:04.360 --> 00:35:10.760
screen mirroring of the local display
on the team monitor.

00:35:10.760 --> 00:35:18.281
The team monitor can show up to
4 different windows at a time

00:35:18.281 --> 00:35:21.281
by changing the screen layout.

00:35:21.281 --> 00:35:27.981
You see this in the left part:
there are 5 different screen layouts.

00:35:27.981 --> 00:35:32.140
Each window supports scrolling and
zooming and other operations

00:35:32.140 --> 00:35:36.720
via the web interface.

00:35:36.720 --> 00:35:39.780
The web user interface is available
in several languages,

00:35:39.780 --> 00:35:43.820
most of them were contributed
by students of our university.

00:35:51.340 --> 00:35:52.781
Each PalMA monitor is controlled by a
Debian GNU Linux system

00:35:54.800 --> 00:35:57.301
running a display server, a window
manager, web server and different kinds

00:35:57.860 --> 00:36:02.020
of viewer applications which are
started on demand.

00:36:02.020 --> 00:36:11.400
The user runs a web browser and optionally
a VNC server for screen mirroring. Today,

00:36:11.400 --> 00:36:19.360
PalMA is usable in a trusted environment
like a university or private network.

00:36:19.360 --> 00:36:25.720
At least 7 libraries currently use it
for group working places.

00:36:25.720 --> 00:36:29.680
Nevertheless we believe that PalMA
can be improved further

00:36:29.680 --> 00:36:39.600
and that there are more useful
applications for PalMA.

00:36:39.600 --> 00:36:44.640
You can find more information
on our website and also on GitHub.

00:36:44.640 --> 00:36:51.300
And I'd be happy to get your feedback or
new contributions for PalMA.

00:36:51.300 --> 00:36:55.341
Maybe there are also Debian developers
who are willing to support special

00:36:55.341 --> 00:36:57.300
software for libraries.

00:36:57.300 --> 00:36:59.740
In any case, just drop me an e-mail.

00:36:59.740 --> 00:37:02.401
Thanks for your attention.

00:37:02.401 --> 00:37:10.020
