+<p>Jeg flikket litt på OpenStreetmap.org i går, og oppdaget ved en
+tilfeldighet at det er en rekke noder som representerer
+overvåkningskamera som ikke blir med på kartet med overvåkningskamera
+i Norge som
+<a href="http://people.skolelinux.org/pere/blog/Kart_over_overv__kningskamera_i_Norge.html">jeg
+laget</a> for snart to år siden. Fra før tok jeg med noder merket med
+man_made=surveillance, mens det er en rekke noder som kun er merket
+med highway=speed_camera. Endret på koden som henter ut kameralisten
+fra OSM, og vips er antall kamera økt til 165.</p>
+
+<a href="http://people.skolelinux.no/pere/surveillance-norway/">Kartet</a>
+er fortsatt ikke komplett, så hvis du ser noen kamera som mangler,
+legg inn ved å følge instruksene fra
+<a href="http://personvern.no/wiki/index.php/Kameraovervåkning">prosjektsiden</a>.
+Hvis du vet om noen flere måter å merke overvåkningskamera i OSM, ta
+kontakt slik at jeg kan få med også disse.</p>

+ <div class="date">2010-12-22 14:55</div>
+ <div class="body">
+<p>The last few days I have spent at work here at the <a
+href="http://www.uio.no/">University of oslo</a> testing if the new
+batch of computers will work with Linux. Every year for the last few
+years the university have organized shared bid of a few thousand
+computers, and this year HP won the bid. Two different desktops and
+five different laptops are on the list this year. We in the UNIX
+group want to know which one of these computers work well with RHEL
+and Ubuntu, the two Linux distributions we currently handle at the
+university.</p>
+
+<p>My test method is simple, and I share it here to get feedback and
+perhaps inspire others to test hardware as well. To test, I PXE
+install the OS version of choice, and log in as my normal user and run
+a few applications and plug in selected pieces of hardware. When
+something fail, I make a note about this in the test matrix and move
+on. If I have some spare time I try to report the bug to the OS
+vendor, but as I only have the machines for a short time, I rarely
+have the time to do this for all the problems I find.</p>
+
+<p>Anyway, to get to the point of this post. Here is the simple tests
+I perform on a new model.</p>
+
+<ul>
+
+<li>Is PXE installation working? I'm testing with RHEL6, Ubuntu Lucid
+and Ubuntu Maverik at the moment. If I feel like it, I also test with
+RHEL5 and Debian Edu/Squeeze.</li>
+
+<li>Is X.org working? If the graphical login screen show up after
+installation, X.org is working.</li>
+
+<li>Is hardware accelerated OpenGL working? Running glxgears (in
+package mesa-utils on Ubuntu) and writing down the frames per second
+reported by the program.</li>
+
+<li>Is sound working? With Gnome and KDE, a sound is played when
+logging in, and if I can hear this the test is successful. If there
+are several audio exits on the machine, I try them all and check if
+the Gnome/KDE audio mixer can control where to send the sound. I
+normally test this by playing
+<a href="http://www.nuug.no/aktiviteter/20101012-chef/ ">a HTML5
+video</a> in Firefox/Iceweasel.</li>
+
+<li>Is the USB subsystem working? I test this by plugging in a USB
+memory stick and see if Gnome/KDE notices this.</li>
+
+<li>Is the CD/DVD player working? I test this by inserting any CD/DVD
+I have lying around, and see if Gnome/KDE notices this.</li>
+
+<li>Is any built in camera working? Test using cheese, and see if a
+picture from the v4l device show up.</li>
+
+<li>Is bluetooth working? Use the Gnome/KDE browsing tool to see if
+any bluetooth devices are discovered. In my office, I normally see a
+few.</li>
+
+<li>For laptops, is the SD or Compaq Flash reader working. I have
+memory modules lying around, and stick them in and see if Gnome/KDE
+notice this.</li>
+
+<li>For laptops, is suspecd/hibernate working? I'm testing if the
+special button work, and if the laptop continue to work after
+resume.</li>
+
+<li>For laptops, is the extra buttons working, like audio level,
+adjusting background light, switching on/off external video output,
+switching on/off wifi, bluetooth, etc? The set of buttons differ from
+laptop to laptop, so I just write down which are working and which are
+not.</li>
+
+<li>Some laptops have smart card readers, finger print readers,
+acceleration sensors etc. I rarely test these, as I do not know how
+to quickly test if they are working or not, so I only document their
+existence.</li>
+
+</ul>
+
+<p>By now I suspect you are really curious what the test results are
+for the HP machines I am testing. I'm not done yet, so I will report
+the test results later. For now I can report that HP 8100 Elite work
+fine, and hibernation fail with HP EliteBook 8440p on Ubuntu Lucid,
+and audio fail on RHEL6. Ubuntu Maverik worked with 8440p. As you
+can see, I have most machines left to test. One interesting
+observation is that Ubuntu Lucid has almost twice the framerate than
+RHEL6 with glxgears. No idea why.</p>

- <div class="date">2010-11-22 11:20</div>
- <div class="body">
-<p>Most of the computers in use by the
-<a href="http://www.skolelinux.org/">Debian Edu/Skolelinux project</a>
-are virtual machines. And they have been Xen machines running on a
-fairly old IBM eserver xseries 345 machine, and we wanted to migrate
-them to KVM on a newer Dell PowerEdge 2950 host machine. This was a
-bit harder that it could have been, because we set up the Xen virtual
-machines to get the virtual partitions from LVM, which as far as I
-know is not supported by KVM. So to migrate, we had to convert
-several LVM logical volumes to partitions on a virtual disk file.</p>
-
-<p>I found
-<a href="http://searchnetworking.techtarget.com.au/articles/35011-Six-steps-for-migrating-Xen-virtual-machines-to-KVM">a
-nice recipe</a> to do this, and wrote the following script to do the
-migration. It uses qemu-img from the qemu package to make the disk
-image, parted to partition it, losetup and kpartx to present the disk
-image partions as devices, and dd to copy the data. I NFS mounted the
-new servers storage area on the old server to do the migration.</p>

-<p>The script is perhaps so simple that it is not copyrightable, but

-
-<p>After doing this, I booted a Debian CD in rescue mode in KVM with
-the new disk image attached, installed grub-pc and linux-image-686 and
-set up grub to boot from the disk image. After this, the KVM machines
-seem to work just fine.</p>
