+ <div class="body"><p>I går ble jeg kontaktet på epost av
+<a href="http://www.digi.no">digi.no</a>s Eirik Rossen som lurte på om
+jeg hadde noen kommentarer til
+<a href="http://www.statkart.no/statkart.ny.no/nor/Statens_kartverk/Om_Statens_kartverk/Pressesenter/Nyhetsarkiv/Nyheter_2012/mai/Norge+i+tet+på+digitale+kartdata.d25-SwZLMWg.ips">kartverkets
+pressemelding</a> om Norges tetplassering når det gjelder
+kart-tilgjengelighet. Jeg svarte følgende, som resulterte i noen
+sitater i
+<a href="http://www.digi.no/895420/norge-i-tet-paa-digitale-kartdata#debatt">Digis
+dekning</a> av kartverkets pressemelding.</p>
+
+<p><blockquote>
+<p>Takk for muligheten til å kommentere.</p>
+
+<p>Pressemeldingen omhandler tilgjengeligheten av kart for aktører som er
+medlem i kartellet Norge Digitalt. Det er ingen overraskelse for meg
+at tilgjengeligheten til kart hos disse medlemmene er god. Men for
+oss på utsiden av kartellet er tilgjengelighet av det som burde være
+felleskapets og innbyggernes kart dårlig.</p>
+
+<p>Bruksvilkårene til kartene fra medlemmene i Norge Digital hindrer
+nyskapning og selv om en er villig til å betale den ublu prisen som
+forlanges får en fortsatt ikke tilgang til kartdata uten
+bruksbegresninger. Derfor bruker jeg heller tid på å gjøre
+fribrukskartet OpenStreetmap bedre. Der fremmer bruksvilkårene
+nyskapning og lar meg skape nye tjenester uten å måtte søke om
+tillatelse fra det offentlige.</p>
+
+<p>En annen problemstilling er jo sikkerhet til fjells og til sjøs.
+Mon tro hvor mange ulykker på sjøen som kunne vært unngått hvis
+sjøkartdata var tilgjengelig uten bruksbegrensninger, slik at enhver
+med GPS eller kartplotter tilnærmet kostnadsfritt kunne sikre seg mest
+mulig oppdaterte sjøkart? Det hjelper jo ikke at offentlige etater
+har enkel tilgang til sjøkartene når det samme ikke gjelder hver
+båtkaptein og småbåtfører. Jeg tror samfunnet som helhet hadde tjent
+på å unngå kostnadene ved disse ulykkene ved å tvinge sjøkartverket
+til å publisere sine kartdata på Internet uten bruksbegresninger.</p>

discovered that there are indeed better tools available. But these

can get them through their suppliers, but their suppliers only sell
companies. The models they sell, are very different from the ones
available from Elkjøp and Lefdal. The main difference is their

- <div class="date"> 6th April 2012</div>
- <div class="body"><p>Recently I have spent time with
-<a href="http://www.slxdrift.no/">Skolelinux Drift AS</a> on speeding
-up a <a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>
-Lenny installation using LTSP diskless workstations, and in the
-process I discovered something very surprising. The reason the KDE
-menu was responding slow when using it for the first time, was mostly
-due to the way KDE find application icons. I discovered that showing
-the Multimedia menu would cause more than 20 000 IP packages to be
-passed between the LTSP client and the NFS server. Most of these were
-
-NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
-ping times between the client and the server were in the range 2-20
-ms, the menus would be very slow. Looking at the strace of kicker in
-Lenny (or plasma-desktop i Squeeze - same problem there), I see that
-the source of these NFS calls are access(2) system calls for
-non-existing files. KDE can do hundreds of access(2) calls to find
-one icon file. In my example, just finding the mplayer icon required
-around 230 access(2) calls.</p>
-
-<p>The KDE code seem to search for icons using a list of icon
-directories, and the list of possible directories is large. In
-(almost) each directory, it look for files ending in .png, .svgz, .svg
-and .xpm. The result is a very slow KDE menu when /usr/ is NFS
-mounted. Showing a single sub menu may result in thousands of NFS
-requests. I am not the first one to discover this. I found a
-<a href="https://bugs.kde.org/show_bug.cgi?id=211416">KDE bug report
-from 2009</a> about this problem, and it is still unsolved.</p>
-
-<p>My solution to speed up the KDE menu was to create a package
-kde-icon-cache that upon installation will look at all .desktop files
-used to generate the KDE menu, find their icons, search the icon paths
-for the file that KDE will end up finding at run time, and copying the
-icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
-these icon files in one of the first directories where KDE will look
-for them. This cut down the number of file accesses required to find
-one icon from several hundred to less than 5, and make the KDE menu
-almost instantaneous. I'm not quite sure where to make the package
-publicly available, so for now it is only available on request.</p>
-
-<p>The bug report mention that this do not only affect the KDE menu
-and icon handling, but also the login process. Not quite sure how to
-speed up that part without replacing NFS with for example NBD, and
-that is not really an option at the moment.</p>
