34 <p>Recently I have spent some time evaluating the multimedia browser
35 plugins available in Debian Lenny, to see which one we should use by
36 default in Debian Edu. We need an embedded video playing plugin with
37 control buttons to pause or stop the video, and capable of streaming
38 all the multimedia content available on the web. The test results and
39 notes are available on
40 <a href="http://wiki.debian.org/DebianEdu/BrowserMultimedia">the
41 Debian wiki</a>. I was surprised how few of the plugins are able to
42 fill this need. My personal video player favorite, VLC, has a really
43 bad plugin which fail on a lot of the test pages. A lot of the MIME
44 types I would expect to work with any free software player (like
45 video/ogg), just do not work. And simple formats like the
46 audio/x-mplegurl format (m3u playlists), just isn't supported by the
47 totem and vlc plugins. I hope the situation will improve soon. No
48 wonder sites use the proprietary Adobe flash to play video.</p>
49
50 <p>For Lenny, we seem to end up with the mplayer plugin. It seem to
51 be the only one fitting our needs. :/</p>

74 <p>This weekend we had a small developer gathering for Debian Edu in
75 Oslo. Most of Saturday was used for the general assemly for the
76 member organization, but the rest of the weekend I used to tune the
77 LTSP installation. LTSP now work out of the box on the 10-network.
78 Acer Aspire One proved to be a very nice thin client, with both
79 screen, mouse and keybard in a small box. Was working on getting the
80 diskless workstation setup configured out of the box, but did not
81 finish it before the weekend was up.</p>
82
83 <p>Did not find time to look at the 4 VGA cards in one box we got from
84 the Brazilian group, so that will have to wait for the next
85 development gathering. Would love to have the Debian Edu installer
86 automatically detect and configure a multiseat setup when it find one
87 of these cards.</p>

112 Et langt steg videre for Debian-prosjektet, og en rekke nye

118 slippes løs på skolene. Takk til alle debian-utviklerne som har
119 gjort dette mulig. Endelig er f.eks. fungerende avhengighetsstyrt

144 <p>The state of standardized LDAP schemas on Linux is far from
145 optimal. There is RFC 2307 documenting one way to store NIS maps in
146 LDAP, and a modified version of this normally called RFC 2307bis, with
147 some modifications to be compatible with Active Directory. The RFC
148 specification handle the content of a lot of system databases, but do
149 not handle DNS zones and DHCP configuration.</p>
150
151 <p>In <a href="http://www.skolelinux.org/">Debian Edu/Skolelinux</a>,
152 we would like to store information about users, SMB clients/hosts,
153 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
154 and LTSP configuration in LDAP. These objects have a lot in common,
155 but with the current LDAP schemas it is not possible to have one
156 object per entity. For example, one need to have at least three LDAP
157 objects for a given computer, one with the SMB related stuff, one with
158 DNS information and another with DHCP information. The schemas
159 provided for DNS and DHCP are impossible to combine into one LDAP
160 object. In addition, it is impossible to implement quick queries for
161 netgroup membership, because of the way NIS triples are implemented.
162 It just do not scale. I believe it is time for a few RFC
163 specifications to cleam up this mess.</p>
164
165 <p>I would like to have one LDAP object representing each computer in
166 the network, and this object can then keep the SMB (ie host key), DHCP
167 (mac address/name) and DNS (name/IP address) settings in one place.
168 It need to be efficently stored to make sure it scale well.</p>
169
170 <p>I would also like to have a quick way to map from a user or
171 computer and to the net group this user or computer is a member.</p>
172
173 <p>Active Directory have done a better job than unix heads like myself
174 in this regard, and the unix side need to catch up. Time to start a
175 new IETF work group?</p>

198 <p>I'm sitting on the train going home from this weekends Debian
199 Edu/Skolelinux development gathering. I got a bit done tuning the
200 desktop, and looked into the dynamic service location protocol
201 implementation avahi. It look like it could be useful for us. Almost
202 30 people participated, and I believe it was a great environment to
203 get to know the Skolelinux system. Walter Bender, involved in the
204 development of the Sugar educational platform, presented his stuff and
205 also helped me improve my OLPC installation. He also showed me that
206 his Turtle Art application can be used in standalone mode, and we
207 agreed that I would help getting it packaged for Debian. As a
208 standalone application it would be great for Debian Edu. We also
209 tried to get the video conferencing working with two OLPCs, but that
210 proved to be too hard for us. The application seem to need more work
211 before it is ready for me. I look forward to getting home and relax
212 now. :)</p>

235 <p>Where I work at the University of Oslo, one decision stand out as a
236 very good one to form a long lived computer infrastructure. It is the
237 simple one, lost by many in todays computer industry: Standardize on
238 open network protocols and open exchange/storage formats, not applications.
239 Applications come and go, while protocols and files tend to stay, and
240 thus one want to make it easy to change application and vendor, while
241 avoiding conversion costs and locking users to a specific platform or
242 application.</p>
243
244 <p>This approach make it possible to replace the client applications
245 independently of the server applications. One can even allow users to
246 use several different applications as long as they handle the selected
247 protocol and format. In the normal case, only one client application
248 is recommended and users only get help if they choose to use this
249 application, but those that want to deviate from the easy path are not
250 blocked from doing so.</p>
251
252 <p>It also allow us to replace the server side without forcing the
253 users to replace their applications, and thus allow us to select the
254 best server implementation at any moment, when scale and resouce
255 requirements change.</p>
256
257 <p>I strongly recommend standardizing - on open network protocols and
258 open formats, but I would never recommend standardizing on a single
259 application that do not use open network protocol or open formats.</p>
