But thanks to +<a href="https://packages.qa.debian.org/i/isenkram.html">my isenkram +package</a> and its recent tasksel extension, it has now become easy +to do this using simple preseeding.</p> + +<p>The isenkram-cli package provide tasksel tasks which will install +firmware for the hardware found in the machine (actually, requested by +the kernel modules for the hardware). (It can also install user space +programs supporting the hardware detected, but that is not the focus +of this story.)</p> + +<p>To get this working in the default installation, two preeseding +values are needed. First, the isenkram-cli package must be installed +into the target chroot (aka the hard drive) before tasksel is executed +in the pkgsel step of the debian-installer system. This is done by +preseeding the base-installer/includes debconf value to include the +isenkram-cli package. The package name is next passed to debootstrap +for installation. With the isenkram-cli package in place, tasksel +will automatically use the isenkram tasks to detect hardware specific +packages for the machine being installed and install them, because +isenkram-cli contain tasksel tasks.</p> + +<p>Second, one need to enable the non-free APT repository, because +most firmware unfortunately is non-free. This is done by preseeding +the apt-mirror-setup step. This is unfortunate, but for a lot of +hardware it is the only option in Debian.</p> + +<p>The end result is two lines needed in your preseeding file to get +firmware installed automatically by the installer:</p> + +<p><blockquote><pre> +base-installer base-installer/includes string isenkram-cli +apt-mirror-setup apt-setup/non-free boolean true +</pre></blockquote></p> + +<p>The current version of isenkram-cli in testing/jessie will install +both firmware and user space packages when using this method. It also +do not work well, so use version 0.15 or later. Installing both +firmware and user space packages might give you a bit more than you +want, so I decided to split the tasksel task in two, one for firmware +and one for user space programs. The firmware task is enabled by +default, while the one for user space programs is not. This split is +implemented in the package currently in unstable.</p> + +<p>If you decide to give this a go, please let me know (via email) how +this recipe work for you if you decide to give it a go. :)</p> + +<p>So, I bet you are wondering, how can this work. First and +foremost, it work because tasksel is modular, and driven by whatever +files it find in /usr/lib/tasksel/ and /usr/share/tasksel/. So the +isenkram-cli package place two files for tasksel to find. First there +is the task description file (/usr/share/tasksel/descs/isenkram.desc):</p> + +<p><blockquote><pre> +Task: isenkram-packages +Section: hardware +Description: Hardware specific packages (autodetected by isenkram) + Based on the detected hardware various hardware specific packages are + proposed. +Test-new-install: show show +Relevance: 8 +Packages: for-current-hardware + +Task: isenkram-firmware +Section: hardware +Description: Hardware specific firmware packages (autodetected by isenkram) + Based on the detected hardware various hardware specific firmware + packages are proposed. +Test-new-install: mark show +Relevance: 8 +Packages: for-current-hardware-firmware +</pre></blockquote></p> + +<p>The key parts are Test-new-install which indicate how the task +should be handled and the Packages line referencing to a script in +/usr/lib/tasksel/packages/. The scripts use other scripts to get a +list of packages to install. The for-current-hardware-firmware script +look like this to list relevant firmware for the machine: + +<p><blockquote><pre> +#!/bin/sh +# +PATH=/usr/sbin:$PATH +export PATH +isenkram-autoinstall-firmware -l +</pre></blockquote></p> + +<p>With those two pieces in place, the firmware is installed by +tasksel during the normal d-i run. :)</p> + +<p>If you want to test what tasksel will install when isenkram-cli is +installed, run <tt>DEBIAN_PRIORITY=critical tasksel --test +--new-install</tt> to get the list of packages that tasksel would +install.</p> + +<p><a href="https://wiki.debian.org/DebianEdu/">Debian Edu</a> will be +pilots in testing this feature, as isenkram is used to install +firmware now.</p> + + + + + Ubuntu used to show the bread prizes at ICA Storo + http://people.skolelinux.org/pere/blog/Ubuntu_used_to_show_the_bread_prizes_at_ICA_Storo.html + http://people.skolelinux.org/pere/blog/Ubuntu_used_to_show_the_bread_prizes_at_ICA_Storo.html + Sat, 4 Oct 2014 15:20:00 +0200 + <p>Today I came across an unexpected Ubuntu boot screen.

We in the Debian Edu team are currently working on +the Jessie based version, trying to get everything in shape before the +freeze, to avoid having to maintain our own package repository in the +future. The +<a href="https://wiki.debian.org/DebianEdu/Status/Jessie">current +status</a> can be seen on the Debian wiki, and there is still heaps of +work left. Some fatal problems block testing, breaking the installer, +but it is possible to work around these to get anyway. Here is a +recipe on how to get the installation limping along.</p> + +<p>First, download the test ISO via +<a href="ftp://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">ftp</a>, +<a href="http://ftp.skolelinux.no/cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso">http</a> +or rsync (use +ftp.skolelinux.org::cd-edu-testing-nolocal-netinst/debian-edu-amd64-i386-NETINST-1.iso). +The ISO build was broken on Tuesday, so we do not get a new ISO every +12 hours or so, but thankfully the ISO we already got we are able to +install with some tweaking.</p> + +<p>When you get to the Debian Edu profile question, go to tty2 +(use Alt-Ctrl-F2), run</p> + +<p><blockquote><pre> +nano /usr/bin/edu-eatmydata-install +</pre></blockquote></p> + +<p>and add 'exit 0' as the second line, disabling the eatmydata +optimization. Return to the installation, select the profile you want +and continue. Without this change, exim4-config will fail to install +due to a known bug in eatmydata.</p> + +<p>When you get the grub question at the end, answer /dev/sda (or if +this do not work, figure out what your correct value would be. All my +test machines need /dev/sda, so I have no advice if it do not fit +your need.</p> + +<p>If you installed a profile including a graphical desktop, log in as +root after the initial boot from hard drive, and install the +education-desktop-XXX metapackage. XXX can be kde, gnome, lxde, xfce +or mate. If you want several desktop options, install more than one +metapackage. Once this is done, reboot and you should have a working +graphical login screen. This workaround should no longer be needed +once the education-tasks package version 1.801 enter testing in two +days.</p> + +<p>I believe the ISO build will start working on two days when the new +tasksel package enter testing and Steve McIntyre get a chance to +update the debian-cd git repository. The eatmydata, grub and desktop +issues are already fixed in unstable and testing, and should show up +on the ISO as soon as the ISO build start working again. Well the +eatmydata optimization is really just disabled. The proper fix +require an upload by the eatmydata maintainer applying the patch +provided in bug <a href="https://bugs.debian.org/702711">#702711</a>. +The rest have proper fixes in unstable.</p> + +<p>I hope this get you going with the installation testing, as we are +quickly running out of time trying to get our Jessie based +installation ready before the distribution freeze in a month.</p> + + + + + Suddenly I am the new upstream of the lsdvd command line tool + http://people.skolelinux.org/pere/blog/Suddenly_I_am_the_new_upstream_of_the_lsdvd_command_line_tool.html + http://people.skolelinux.org/pere/blog/Suddenly_I_am_the_new_upstream_of_the_lsdvd_command_line_tool.html + Thu, 25 Sep 2014 11:20:00 +0200 + <p>I use the <a href="https://sourceforge.net/p/lsdvd/">lsdvd tool</a> +to handle my fairly large DVD collection.

This text is about how the -text processing of this manual is handled in the project.</p> - -<p>One goal of the project is to provide information in the native -language of its users, and for this we need to handle translations. -But we also want to make sure each language contain the same -information, so for this we need a good way to keep the translations -in sync. And we want it to be easy for our users to improve the -documentation, avoiding the need to learn special formats or tools to -contribute, and the obvious way to do this is to make it possible to -edit the documentation using a web browser. We also want it to be -easy for translators to keep the translation up to date, and give them -help in figuring out what need to be translated. Here is the list of -tools and the process we have found trying to reach all these -goals.</p> - -<p>We maintain the authoritative source of our manual in the -<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/">Debian -wiki</a>, as several wiki pages written in English. It consist of one -front page with references to the different chapters, several pages -for each chapter, and finally one "collection page" gluing all the -chapters together into one large web page (aka -<a href="https://wiki.debian.org/DebianEdu/Documentation/Wheezy/AllInOne">the -AllInOne page</a>). The AllInOne page is the one used for further -processing and translations. Thanks to the fact that the -<a href="http://moinmo.in/">MoinMoin</a> installation on -wiki.debian.org support exporting pages in -<a href="http://www.docbook.org/">the Docbook format</a>, we can fetch -the list of pages to export using the raw version of the AllInOne -page, loop over each of them to generate a Docbook XML version of the -manual. This process also download images and transform image -references to use the locally downloaded images. The generated -Docbook XML files are slightly broken, so some post-processing is done -using the <tt>documentation/scripts/get_manual</tt> program, and the -result is a nice Docbook XML file (debian-edu-wheezy-manual.xml) and -a handfull of images. The XML file can now be used to generate PDF, HTML -and epub versions of the English manual. This is the basic step of -our process, making PDF (using dblatex), HTML (using xsltproc) and -epub (using dbtoepub) version from Docbook XML, and the resulting files -are placed in the debian-edu-doc-en binary package.</p> - -<p>But English documentation is not enough for us. We want translated -documentation too, and we want to make it easy for translators to -track the English original. For this we use the -<a href="http://packages.qa.debian.org/p/poxml.html">poxml</a> package, -which allow us to transform the English Docbook XML file into a -translation file (a .pot file), usable with the normal gettext based -translation tools used by those translating free software. The pot -file is used to create and maintain translation files (several .po -files), which the translations update with the native language -translations of all titles, paragraphs and blocks of text in the -original. The next step is combining the original English Docbook XML -and the translation file (say debian-edu-wheezy-manual.nb.po), to -create a translated Docbook XML file (in this case -debian-edu-wheezy-manual.nb.xml). This translated (or partly -translated, if the translation is not complete) Docbook XML file can -then be used like the original to create a PDF, HTML and epub version -of the documentation.</p> - -<p>The translators use different tools to edit the .po files. We -recommend using -<a href="http://www.kde.org/applications/development/lokalize/">lokalize</a>, -while some use emacs and vi, others can use web based editors like -<a href="http://pootle.translatehouse.org/">Poodle</a> or -<a href="https://www.transifex.com/">Transifex</a>. All we care about -is where the .po file end up, in our git repository. Updated -translations can either be committed directly to git, or submitted as -<a href="https://bugs.debian.org/src:debian-edu-doc">bug reports -against the debian-edu-doc package</a>.</p> - -<p>One challenge is images, which both might need to be translated (if -they show translated user applications), and are needed in different -formats when creating PDF and HTML versions (epub is a HTML version in -this regard). For this we transform the original PNG images to the -needed density and format during build, and have a way to provide -translated images by storing translated versions in -images/$LANGUAGECODE/. I am a bit unsure about the details here. The -package maintainers know more.</p> - -<p>If you wonder what the result look like, we provide -<a href="http://maintainer.skolelinux.org/debian-edu-doc/">the content -of the documentation packages on the web</a>.

Rapporterte -nettopp -<a href="https://github.com/rg3/youtube-dl/issues/2980">problemet til -utviklerne</a>, og antar de får fikset det snart.</p> - -<p>Dermed er alt klart til å laste ned dokumentarene om -<a href="http://tv.nrk.no/program/KOID23005014/usas-hemmelige-avlytting">USAs -hemmelige avlytting</a> og -<a href="http://tv.nrk.no/program/KOID23005114/selskapene-bak-usas-avlytting">Selskapene -bak USAs avlytting</a>, i tillegg til -<a href="http://tv.nrk.no/program/KOID20005814/et-moete-med-edward-snowden">intervjuet -med Edward Snowden gjort av den tyske tv-kanalen ARD</a>. Anbefaler -alle å se disse, sammen med -<a href="http://media.ccc.de/browse/congress/2013/30C3_-_5713_-_en_-_saal_2_-_201312301130_-_to_protect_and_infect_part_2_-_jacob.html">foredraget -til Jacob Appelbaum på siste CCC-konferanse</a>, for å forstå mer om -hvordan overvåkningen av borgerne brer om seg.</p> - -<p>Takk til gode venner på foreningen NUUGs IRC-kanal -<a href="irc://irc.freenode.net/%23nuug">#nuug på irc.freenode.net</a> -for tipsene som fikk meg i mål</a>.</p> - -<p><strong>Oppdatering 2014-06-17</strong>: Etter at jeg publiserte -denne, ble jeg tipset om bloggposten -"<a href="http://ingvar.blog.redpill-linpro.com/2012/05/31/downloading-hd-content-from-tv-nrk-no/">Downloading -HD content from tv.nrk.no</a>" av Ingvar Hagelund, som har alternativ -implementasjon og tips for å lage mkv-fil med undertekstene inkludert. -Kanskje den passer bedre for deg? I tillegg ble feilen i youtube-dl -ble fikset litt senere ut på dagen i går, samt at youtube-dl fikk -støtte for å laste ned undertitler. Takk til Anders Einar Hilden for -god innsats og youtube-dl-utviklerne for rask respons.</p> - - - - - Free software car computer solution? - http://people.skolelinux.org/pere/blog/Free_software_car_computer_solution_.html - http://people.skolelinux.org/pere/blog/Free_software_car_computer_solution_.html - Thu, 29 May 2014 18:45:00 +0200 - <p>Dear lazyweb. I'm planning to set up a small Raspberry Pi computer -in my car, connected to -<a href="http://www.dx.com/p/400a-4-0-tft-lcd-digital-monitor-for-vehicle-parking-reverse-camera-1440x272-12v-dc-57776">a -small screen</a> next to the rear mirror. I plan to hook it up with a -GPS and a USB wifi card too. The idea is to get my own -"<a href="http://en.wikipedia.org/wiki/Carputer">Carputer</a>". But I -wonder if someone already created a good free software solution for -such car computer.</p> - -<p>This is my current wish list for such system:</p> - -<ul> - - <li>Work on Raspberry Pi.</li> - - <li>Show current speed limit based on location, and warn if going too - fast (for example using color codes yellow and red on the screen, - or make a sound). This could be done either using either data from - <a href="http://www.openstreetmap.org/">Openstreetmap</a> or OCR - info gathered from a dashboard camera.</li> - - <li>Track automatic toll road passes and their cost, show total spent - and make it possible to calculate toll costs for planned - route.</li> - - <li>Collect GPX tracks for use with OpenStreetMap.</li> - - <li>Automatically detect and use any wireless connection to connect - to home server. Try IP over DNS - (<a href="http://dev.kryo.se/iodine/">iodine</a>) or ICMP - (<a href="http://code.gerade.org/hans/">Hans</a>) if direct - connection do not work.</li> - - <li>Set up mesh network to talk to other cars with the same system, - or some standard car mesh protocol.</li> - - <li>Warn when approaching speed cameras and speed camera ranges - (speed calculated between two cameras).</li> - - <li>Suport dashboard/front facing camera to discover speed limits and - run OCR to track registration number of passing cars.</li> - -</ul> - -<p>If you know of any free software car computer system supporting -some or all of these features, please let me know.</p> - - -
