When we install more than 2000 packages in -<a href="http://www.skolelinux.org/">Skolelinux / Debian Edu</a> using -tasksel in the installer, unpacking the binary packages take forever. -A part of the slow I/O issue was discussed in -<a href="https://bugs.debian.org/613428">bug #613428</a> about too -much file system sync-ing done by dpkg, which is the package -responsible for unpacking the binary packages. Other parts (like code -executed by postinst scripts) might also sync to disk during -installation. All this sync-ing to disk do not really make sense to -me. If the machine crash half-way through, I start over, I do not try -to salvage the half installed system. So the failure sync-ing is -supposed to protect against, hardware or system crash, is not really -relevant while the installer is running.</p> - -<p>A few days ago, I thought of a way to get rid of all the file -system sync()-ing in a fairly non-intrusive way, without the need to -change the code in several packages. The idea is not new, but I have -not heard anyone propose the approach using dpkg-divert before. It -depend on the small and clever package -<a href="https://packages.qa.debian.org/eatmydata">eatmydata</a>, which -uses LD_PRELOAD to replace the system functions for syncing data to -disk with functions doing nothing, thus allowing programs to live -dangerous while speeding up disk I/O significantly. Instead of -modifying the implementation of dpkg, apt and tasksel (which are the -packages responsible for selecting, fetching and installing packages), -it occurred to me that we could just divert the programs away, replace -them with a simple shell wrapper calling -"eatmydata&nbsp;$program&nbsp;$@", to get the same effect. -Two days ago I decided to test the idea, and wrapped up a simple -implementation for the Debian Edu udeb.</p> - -<p>The effect was stunning. In my first test it reduced the running -time of the pkgsel step (installing tasks) from 64 to less than 44 -minutes (20 minutes shaved off the installation) on an old Dell -Latitude D505 machine. I am not quite sure what the optimised time -would have been, as I messed up the testing a bit, causing the debconf -priority to get low enough for two questions to pop up during -installation. As soon as I saw the questions I moved the installation -along, but do not know how long the question were holding up the -installation. I did some more measurements using Debian Edu Jessie, -and got these results. The time measured is the time stamp in -/var/log/syslog between the "pkgsel: starting tasksel" and the -"pkgsel: finishing up" lines, if you want to do the same measurement -yourself. In Debian Edu, the tasksel dialog do not show up, and the -timing thus do not depend on how quickly the user handle the tasksel -dialog.</p> - -<p><table> - -<tr> -<th>Machine/setup</th> -<th>Original tasksel</th> -<th>Optimised tasksel</th> -<th>Reduction</th> -</tr> - -<tr> -<td>Latitude D505 Main+LTSP LXDE</td> -<td>64 min (07:46-08:50)</td> -<td><44 min (11:27-12:11)</td> -<td>>20 min 18%</td> -</tr> - -<tr> -<td>Latitude D505 Roaming LXDE</td> -<td>57 min (08:48-09:45)</td> -<td>34 min (07:43-08:17)</td> -<td>23 min 40%</td> -</tr> - -<tr> -<td>Latitude D505 Minimal</td> -<td>22 min (10:37-10:59)</td> -<td>11 min (11:16-11:27)</td> -<td>11 min 50%</td> -</tr> - -<tr> -<td>Thinkpad X200 Minimal</td> -<td>6 min (08:19-08:25)</td> -<td>4 min (08:04-08:08)</td> -<td>2 min 33%</td> -</tr> - -<tr> -<td>Thinkpad X200 Roaming KDE</td> -<td>19 min (09:21-09:40)</td> -<td>15 min (10:25-10:40)</td> -<td>4 min 21%</td> -</tr> - -</table></p> - -<p>The test is done using a netinst ISO on a USB stick, so some of the -time is spent downloading packages.

Download typically took a few -seconds to a few minutes, depending on the amount of packages being -installed.</p> - -<p>The speedup is implemented by using two hooks in -<a href="https://www.debian.org/devel/debian-installer/">Debian -Installer</a>, the pre-pkgsel.d hook to set up the diverts, and the -finish-install.d hook to remove the divert at the end of the -installation. I picked the pre-pkgsel.d hook instead of the -post-base-installer.d hook because I test using an ISO without the -eatmydata package included, and the post-base-installer.d hook in -Debian Edu can only operate on packages included in the ISO. The -negative effect of this is that I am unable to activate this -optimization for the kernel installation step in d-i. If the code is -moved to the post-base-installer.d hook, the speedup would be larger -for the entire installation.</p> - -<p>I've implemented this in the -<a href="https://packages.qa.debian.org/debian-edu-install">debian-edu-install</a> -git repository, and plan to provide the optimization as part of the -Debian Edu installation. If you want to test this yourself, you can -create two files in the installer (or in an udeb).

Some channels are very load, others are less loud, and +ads tend to shout very high to get the attention of the viewers, and +the viewers do not like this. This fact is well known to the TV +channels. See for example the BBC white paper +"<a href="http://downloads.bbc.co.uk/rd/pubs/whp/whp-pdf-files/WHP202.pdf">Terminology +for loudness and level dBTP, LU, and all that</a>" from 2011 for a +summary of the problem domain. To better address the need for even +loadness, the TV channels got together several years ago to agree on a +new way to measure loudness in digital files as one step in +standardizing loudness. From this came the ITU-R standard BS.1770, +"<a href="http://www.itu.int/rec/R-REC-BS.1770/en">Algorithms to +measure audio programme loudness and true-peak audio level</a>".</p> + +<p>The ITU-R BS.1770 specification describe an algorithm to measure +loadness in LUFS (Loudness Units, referenced to Full Scale). But +having a way to measure is not enough. To get the same loudness +across TV channels, one also need to decide which value to standardize +on. For European TV channels, this was done in the EBU Recommondaton +R128, "<a href="https://tech.ebu.ch/docs/r/r128.pdf">Loudness +normalisation and permitted maximum level of audio signals</a>", which +specifies a recommended level of -23 LUFS. In Norway, I have been +told that NRK, TV2, MTG and SBS have decided among themselves to +follow the R128 recommondation for playout from 2016-03-01.</p> + +<p>There are free software available to measure and adjust the loudness +level using the LUFS. In Debian, I am aware of a library named +<a href="https://tracker.debian.org/pkg/libebur128">libebur128</a> +able to measure the loudness and since yesterday morning a new binary +named <a href="http://bs1770gain.sourceforge.net">bs1770gain</a> +capable of both measuring and adjusting was uploaded and is waiting +for NEW processing. I plan to maintain the latter in Debian under the +<a href="https://qa.debian.org/developer.php?email=pkg-multimedia-maintainers%40lists.alioth.debian.org">Debian +multimedia</a> umbrella.</p> + +<p>The free software based TV channel I am involved in, +<a href="http://www.frikanalen.no/">Frikanalen</a>, plan to follow the +R128 recommondation ourself as soon as we can adjust the software to +do so, and the bs1770gain tool seem like a good fit for that part of +the puzzle to measure loudness on new video uploaded to Frikanalen. +Personally, I plan to use bs1770gain to adjust the loudness of videos +I upload to Frikanalen on behalf of <a href="http://www.nuug.no/">the +NUUG member organisation</a>. The program seem to be able to measure +the LUFS value of any media file handled by ffmpeg, but I've only +successfully adjusted the LUFS value of WAV files. I suspect it +should be able to adjust it for all the formats handled by ffmpeg.</p> - Do you need an agreement with MPEG-LA to publish and broadcast H.264 video in Norway? - http://people.skolelinux.org/pere/blog/Do_you_need_an_agreement_with_MPEG_LA_to_publish_and_broadcast_H_264_video_in_Norway_.html - http://people.skolelinux.org/pere/blog/Do_you_need_an_agreement_with_MPEG_LA_to_publish_and_broadcast_H_264_video_in_Norway_.html - Mon, 25 Aug 2014 22:10:00 +0200 - <p>Two years later, I am still not sure if it is legal here in Norway -to use or publish a video in H.264 or MPEG4 format edited by the -commercially licensed video editors, without limiting the use to -create "personal" or "non-commercial" videos or get a license -agreement with <a href="http://www.mpegla.com">MPEG LA</a>.

Har NRK vurdert om +det er behov for en patentavtale med +<a href="http://www.mpegla.com/">MPEG LA</a> slik det står i +programvarelisensene til blant annet Apple Final Cut Studio, Adobe +Premiere Pro, Avid og Apples Final Cut Pro X?</p> + +<p>Hvis dere har vurdert dette, hva var utfallet av en slik vurdering?</p> + +<p>Hvis dere ikke har vurdert dette, har NRK planer om å vurdere behovet +for patentavtale?</p> + +<p>I følge en artikkel på +<a href="https://nrkbeta.no/2012/02/01/siste-kutt-for-final-cut/">NRK +Beta i 2012</a> har NRK brukt eller testet både Apple Final Cut +Studio, Adobe Premiere Pro, Avid og Apples Final Cut Pro X til bruk +for å redigere video før sending. Alle disse har bruksvilkår +understøttet av opphavsretten som sier at de kun kan brukes til å lage +filmer til personlig og ikke-kommersiell bruk - med mindre en har en +lisensavtale med MPEG LA om bruk av patenter utstedt i USA for H.264. +Se f.eks. <a href="http://www.avid.com/static/resources/common/documents/corporate/LICENSE.pdf">bruksvilkårene for Avid</a>, <a href="http://news.cnet.com/8301-30685_3-20000101-264.html">Adobe Premiere</a> og <a href="http://images.apple.com/legal/sla/docs/finalcutstudio2.pdf">Apple Final +Cut Studio</a> og søk etter "MPEG LA".</p> + +<p>Dette får meg til å lure på om det er brudd på opphavsretten å bruke +disse verktøyene i strid med bruksvilkårene uten patentavtale med MPEG +LA.

Dette forteller meg at selv om +produsentene av utstyr og programvare som NRK bruker har en slik avtale +med MPEG LA, så trenges det en egen avtale for å kringkaste video på det +formatet.</p> + +<p>I følge Ryan Rodriguez hos MPEG LA, da jeg spurte ham på epost i +juni 2012, har NRK ikke en slik avtale med MPEG LA.

Det skrives som om det +blir valgfritt, på samme måten som det skrives passloven, der det i +loven sier at det kan +«<a href="https://lovdata.no/dokument/NL/lov/1997-06-19-82#§6">innhentes +og lagres i passet biometrisk personinformasjon i form av ansiktsfoto +og fingeravtrykk (to fingre)</a>». Men på tross av bruken av «kan» i +passloven er det innført krav om å avgi fingeravtrykk for å få et pass +i Norge. Proposisjonen sier i tillegg i del 1 (Proposisjonens +hovedinnhold) at ID-kortene skal være like pålitelig som pass og ha +samme sikkerhetsnivå som pass. Departementet foreslår altså at +ID-kortene skal gis etter samme regler som for pass.</p> + +<p>Formuleringene fra hovedinnholdet i proposisjonen er videreført i +<a href="https://www.stortinget.no/no/Saker-og-publikasjoner/Publikasjoner/Innstillinger/Stortinget/2014-2015/inns-201415-243/?lvl=0">innstillingen +fra stortingskomiteen</a>, der det konkret står «De foreslåtte reglene +vil gi befolkningen tilbud om et offentlig utstedt identitetsbevis som +vil være like pålitelig som passet, og mer praktisk å bruke som +legitimasjon» og «Det nasjonale ID-kortet skal også holde samme +sikkerhetsnivå som passet». Komiteen har altså ingen kommentarer +eller innsigelser til dette forslaget, og gjorde i debatten da saken +ble vedtatt det klart at dette var en god sak og at en enstemmig +komité var glad for resultatet. Stortinget har dermed stilt seg helt +og fullt bak departementets forslag.</p> + +<p>For meg er det åpenbart når en leser proposisjonen at «like +pålitelig» og «samme sikkerhetsnivå» vil bli tolket av departementet +som «med samme biometrisk informasjon som i passene», og departementet +forklarer i tillegg i proposisjonen at de har tenkt at +fingeravtrykkene «vil bli beskyttet på samme måte som fingeravtrykkene +i passene». Jeg ser det dermed som åpenbart at den samme +tvangsinnhentingen av fingeravtrykk som gjelder for pass vil bli +viderført til de nasjonale ID-kortene.</p> + +<p>Det eneste som kan endre dette er massive protester fra +befolkningen på at folk som ikke er mistenkt for noe kriminelt skal +tvinges til å gi fingeravtrykket til politiet for å f.eks. kunne få +bankkonto eller stemme ved valg. Det kunne få departementet til å +snu. Det tror jeg ikke vil skje.</p> + + + + + Norwegian citizens now required by law to give their fingerprint to the police + http://people.skolelinux.org/pere/blog/Norwegian_citizens_now_required_by_law_to_give_their_fingerprint_to_the_police.html + http://people.skolelinux.org/pere/blog/Norwegian_citizens_now_required_by_law_to_give_their_fingerprint_to_the_police.html + Sun, 10 May 2015 16:00:00 +0200 + <p>5 days ago, the Norwegian Parliament decided, unanimously, that all +citizens of Norway, no matter if they are suspected of something +criminal or not, are +<a href="https://www.holderdeord.no/votes/1430838871e">required to +give fingerprints to the police</a> (vote details from Holder de +ord). The law make it sound like it will be optional, but in a few +years there will be no option any more. The ID will be required to +vote, to get a bank account, a bank card, to change address on the +post office, to receive an electronic ID or to get a drivers license +and many other tasks required to function in Norway. The banks plan +to stop providing their own ID on the bank cards when this new +national ID is introduced, and the national road authorities plan to +change the drivers license to no longer be usable as identity cards. +In effect, to function as a citizen in Norway a national ID card will +be required, and to get it one need to provide the fingerprints to +the police.</p> + +<p>In addition to handing the fingerprint to the police (which +promised to not make a copy of the fingerprint image at that point in +time, but say nothing about doing it later), a picture of the +fingerprint will be stored on the RFID chip, along with a picture of +the face and other information about the person. Some of the +information will be encrypted, but the encryption will be the same +system as currently used in the passports. The codes to decrypt will +be available to a lot of government offices and their suppliers around +the globe, but for those that do not know anyone in those circles it +is good to know that +<a href="http://www.theguardian.com/technology/2006/nov/17/news.homeaffairs">the +encryption is already broken</a>. And they +<a href="http://www.networkworld.com/article/2215057/wireless/bad-guys-could-read-rfid-passports-at-217-feet--maybe-a-lot-more.html">can +be read from 70 meters away</a>. This can be mitigated a bit by +keeping it in a Faraday cage (metal box or metal wire container), but +one will be required to take it out of there often enough to expose +ones private and personal information to a lot of people that have no +business getting access to that information.</p> + +<p>The new Norwegian national IDs are a vehicle for identity theft, +and I feel sorry for us all having politicians accepting such invasion +of privacy without any objections. So are the Norwegian passports, +but it has been possible to function in Norway without those so far. +That option is going away with the passing of the new law. In this, I +envy the Germans, because for them it is optional how much biometric +information is stored in their national ID.</p> + +<p>And if forced collection of fingerprints was not bad enough, the +information collected in the national ID card register can be handed +over to foreign intelligence services and police authorities, "when +extradition is not considered disproportionate".</p> + +<p>Update 2015-05-12: For those unable to believe that the Parliament +really could make such decision, I wrote +<a href="http://people.skolelinux.org/pere/blog/Blir_det_virkelig_krav_om_fingeravtrykk_i_nasjonale_ID_kort_.html">a +summary of the sources I have</a> for concluding the way I do +(Norwegian Only, as the sources are all in Norwegian).</p> + + + + + What would it cost to store all phone calls in Norway? + http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html + http://people.skolelinux.org/pere/blog/What_would_it_cost_to_store_all_phone_calls_in_Norway_.html + Fri, 1 May 2015 19:30:00 +0200 + <p>Many years ago, a friend of mine calculated how much it would cost +to store the sound of all phone calls in Norway, and came up with the +cost of around 20 million NOK (2.4 mill EUR) for all the calls in a +year. I got curious and wondered what the same calculation would look +like today. To do so one need an idea of how much data storage is +needed for each minute of sound, how many minutes all the calls in +Norway sums up to, and the cost of data storage.</p> + +<p>The 2005 numbers are from +<a href="http://www.digi.no/analyser/2005/10/04/vi-prater-stadig-mindre-i-roret">digi.no</a>, +the 2012 numbers are from +<a href="http://www.nkom.no/aktuelt/nyheter/fortsatt-vekst-i-det-norske-ekommarkedet">a +NKOM report</a>, and I got the 2013 numbers after asking NKOM via +email. I was told the numbers for 2014 will be presented May 20th, +and decided not to wait for those, as I doubt they will be very +different from the numbers from 2013.</p> + +<p>The amount of data storage per minute sound depend on the wanted +quality, and for phone calls it is generally believed that 8 Kbit/s is +enough. See for example a +<a href="http://www.cisco.com/c/en/us/support/docs/voice/voice-quality/7934-bwidth-consume.html#topic1">summary +on voice quality from Cisco</a> for some alternatives. 8 Kbit/s is 60 +Kbytes/min, and this can be multiplied with the number of call minutes +to get the storage requirements.</p> + +<p>Storage prices varies a lot, depending on speed, backup strategies, +availability requirements etc. But a simple way to calculate can be +to use the price of a TiB-disk (around 1000 NOK / 120 EUR) and double +it to take space, power and redundancy into account. It could be much +higher with high speed and good redundancy requirements.</p> + +<p>But back to the question, What would it cost to store all phone +calls in Norway? Not much. Here is a small table showing the +estimated cost, which is within the budget constraint of most medium +and large organisations:</p> + +<table border="1"> +<tr><th>Year</th><th>Call minutes</th><th>Size</th><th>Price in NOK / EUR</th></tr> +<tr><td>2005</td><td align="right">24 000 000 000</td><td align="right">1.3 PiB</td><td align="right">3 mill / 358 000</td></tr> +<tr><td>2012</td><td align="right">18 000 000 000</td><td align="right">1.0 PiB</td><td align="right">2.2 mill / 262 000</td></tr> +<tr><td>2013</td><td align="right">17 000 000 000</td><td align="right">950 TiB</td><td align="right">2.1 mill / 250 000</td></tr> +</table> + +<p>This is the cost of buying the storage. Maintenance need to be +taken into account too, but calculating that is left as an exercise +for the reader. But it is obvious to me from those numbers that +recording the sound of all phone calls in Norway is not going to be +stopped because it is too expensive. I wonder if someone already is +collecting the data?</p> - Lenker for 2014-08-03 - http://people.skolelinux.org/pere/blog/Lenker_for_2014_08_03.html - http://people.skolelinux.org/pere/blog/Lenker_for_2014_08_03.html - Sun, 3 Aug 2014 23:00:00 +0200 - <p>Lenge siden jeg har hatt tid til å publisere lenker til skriverier -jeg har hatt glede og nytte av av å lese.

A netbooting environment is prepared using PXE, so after +initial installation of the main server from CD or USB stick all other +machines can be installed via the network. The provided school server +provides LDAP database and Kerberos authentication service, +centralized home directories, DHCP server, web proxy and many other +services. The desktop contains more than 60 educational software +packages and more are available from the Debian archive, and schools +can choose between KDE, GNOME, LXDE, Xfce and MATE desktop +environment. + +== About Debian == + +The Debian Project was founded in 1993 by Ian Murdock to be a truly +free community project. Since then the project has grown to be one of +the largest and most influential open source projects. Thousands of +volunteers from all over the world work together to create and +maintain Debian software. Available in 70 languages, and supporting a +huge range of computer types, Debian calls itself the universal +operating system. + +== Thanks == + +Thanks to everyone making Debian and Debian Edu / Skolelinux happen! +You rock. +</pre> - Debian Edu interview: Bernd Zeitzen - http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Bernd_Zeitzen.html - http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Bernd_Zeitzen.html - Thu, 31 Jul 2014 08:30:00 +0200 - <p>The complete and free “out of the box” software solution for -schools, <a href="http://www.skolelinux.org/">Debian Edu / -Skolelinux</a>, is used quite a lot in Germany, and one of the people -involved is Bernd Zeitzen, who show up on the project mailing lists -from time to time with interesting questions and tips on how to adjust -the setup. I managed to interview him this summer.</p> + Debian Edu interview: Shirish Agarwal + http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Shirish_Agarwal.html + http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Shirish_Agarwal.html + Wed, 15 Apr 2015 09:20:00 +0200 + <p>It was a surprise to me to learn that project to create a complete +computer system for schools I've involved in, +<a href="http://www.skolelinux.org/">Debian Edu / Skolelinux</a>, was +being used in India. But apparently it is, and I managed to get an +interview with one of the friends of the project there, Shirish +Agarwal.</p> <p><strong>Who are you, and how do you spend your days?</strong></p> -<p>My name is Bernd Zeitzen and I'm married with Hedda, a self -employed physiotherapist. My former profession is tool maker, but I -haven't worked for 30 years in this job. 30 years ago I started to -support my wife and become her officeworker and a few years later the -administrator for a small computer network, today based on Ubuntu -Server (Samba, OpenVPN). For her daily work she has to use Windows -Desktops because the software she needs to organize her business only -works with Windows . :-(</p> - -<p>In 1988 we started with one PC and DOS, then I learned to use -Windows 98, 2000, XP, …, 8, Ubuntu, MacOSX. Today we are running a -Linux server with 6 Windows clients and 10 persons (teacher of -children with special needs, speech therapist, occupational therapist, -psychologist and officeworkers) using our Samba shares via OpenVPN to -work with the documentations of our patients.</p> +<p>My name is Shirish Agarwal. Based out of the educational and +historical city of Pune, from the western state of Maharashtra, India. +My bread comes from giving training, giving policy tips, +installations on free software to mom and pop shops in different +fields from Desktop publishing to retail shops as well as work with +few software start-ups as well.</p> <p><strong>How did you get in contact with the Skolelinux / Debian Edu project?</strong></p> -<p>Two years ago a friend of mine asked me, if I want to get a job in -his school (<a href="http://www.gymnasium-harsewinkel.de/">Gymnasium -Harsewinkel</a>). They started with Skolelinux / Debian Edu and they -were looking for people to give support to the teachers using the -software and the network and teaching the pupils increasing their -computer skills in optional lessons. I'm spending 4-6 hours a week -with this job.</p> +<p>It started innocently enough. I have been using Debian for a few +years and in one local minidebconf / debutsav I was asked if there was +anything for schools or education. I had worked / played with free +educational softwares such as Gcompris and Stellarium for my many +nieces and nephews so researched and found Debian Edu or Skolelinux as +it was known then. Since then I have started using the various +education meta-packages provided by the project.</p> <p><strong>What do you see as the advantages of Skolelinux / Debian Edu?</strong></p> -<p>The independence.</p> - -<p>First: Every person is allowed to use, share and develop the -software. Even if you are poor, you are allowed to use the software -included in Skolelinux/Debian Edu and all the other Free Software.</p> - -<p>Second: The software runs on old machines and this gives us the -possibility to recycle computers, weeded out from offices. The -servers and desktops are running for more than two years and they are -working reliable. </p> - -<p>We have two servers (one tjener and one terminal server), 45 -workstations in three classrooms and seven laptops as a mobile -solution for all classrooms. These machines are all booting from the -terminal server. In the moment we are installing 30 laptops as mobile -workstations. Then the pupils have the possibility to work with these -machines in their classrooms. Internet access is realized by a WLAN -router, connected to the schools network. This is all done without a -dedicated system administrator or a computer science teacher.</p> +<p>It's closest I have seen where a package full of educational +software are packed, which are free and open (both literally and +figuratively). Even if I take the simplest software which is +gcompris, the number of activities therein are amazing. Another one of +the softwares that I have liked for a long time is stellarium. Even +pysycache is cool except for couple of issues I encountered +<a href="https://bugs.debian.org/781841">#781841</a> and +<a href="https://bugs.debian.org/781842">#781842</a>.</p> + +<p>I prefer software installed on the system over web based solutions, +as a web site can disappear any time but the software on disk has the +possibility of a larger life span. Of course with both it's more a +question if it has enough users who make it fun or sustainable or both +for the developer per-se.</p> <p><strong>What do you see as the disadvantages of Skolelinux / Debian Edu?</strong></p> -<p>Teachers and pupils are Windows users. &lt;Irony on&gt; And Linux -isn't cool. It's software for freaks using the command line. &lt;Irony -off&gt; They don't realize the stability of the system. </p> +<p>I do see that the Debian Edu team seems to be short-handed and I +think more efforts should be made to make it popular and ask and take +help from people and the larger community wherever possible.</p> + +<p>I don't see any disadvantage to use Skolelinux apart from the fact +that most apps. are generic which is good or bad how you see it. +However, saying that I do acknowledge the fact that the canvas is +pretty big and there are lot of interesting ideas that could be done +but for reasons not known not done or if done I don't know about them. +Let me share some of the ideas (these are more upstream based but +still) I have had for a long time :</p> + +<p>1. Classical maths question of two trains in opposing directions +each running @x kmph/mph at y distance, when they will meet and how +far would each travel and similar questions like these. + +<p>The computer is a fantastic system where questions like these can +be drawn, animated and the methodology and answers teased out in +interactive manner. While sites such as the +<a href="http://mathforum.org/dr.math/faq/faq.two.trains.html">Ask +Dr. Math FAQ on The Two Trains problem</a> (as an example or point of +inspiration) can be used there is lot more that can be done. I dunno +if there is a free software which does something like this. The idea +being a blend of objects + animation + interaction which does +this. The whole interaction could be gamified with points or sounds or +colourful celebration whenever the user gets even part of the question +or/and methodology right. That would help reinforce good behaviour. +This understanding could be used to share/showcase everything from how +the first wheel came to be, to evolution to how astronomy started, +psychics and everything in-between.</p> + +<p>One specific idea in the train part was having the Linux mascot on +one train and the BSD or GNU mascot on the other train and they +meeting somewhere in-between. Characters from blender movies could +also be used.</p> + +<p>2. Loads of crossword-puzzles with reference to subjects: We have +enormous data sets in Wikipedia and Wikitionary. I don't think it +should be a big job to design crossword puzzles. Using categories and +sub-categories it should be doable to have Q&A single word answers +from the existing data-sets. What would make it easy or hard could be +the length of the word + existence of many or few vowels depending on +the user's input.</p> + +<p>3. Jigsaw puzzles - We already have a great software called +palapeli with number of slicers making it pretty interesting. What +needs to be done is to download large number of public domain and +copyleft images, tease and use IPTC tags to categorise them into +nature, history etc. and let it loose. This could turn to be really +huge collection of images. One source could be taken from +commons.wikimedia.org, others could be huge collection of royalty-free +stock photos. Potential is immense.</p> + +<p>Apart from this, free software suffers in two directions, we lag +both in development (of using new features per-se) and maintenance a +lot. This is more so in educational software as these applications +need to be timely and the opportunity cost of missing deadlines is +immense. If we are able to solve issues of funding for development and +maintenance of such software I don't see any big difficulties. I know +of few start-ups in and around India who would love to develop and +maintain such software if funding issues could be solved.</p> <p><strong>Which free software do you use daily?</strong></p> -<p>Firefox, Thunderbird, LibreOffice, Ubuntu Server 12.04 (Samba, -Apache, MySQL, Joomla!, … and Skolelinux / Debian Edu)</p> +<p>That would be huge list. Some of the softwares are obviously apt, +aptitude, debdelta, leafpad, the shell of course (zsh nowadays), +quassel for IRC. In games I use shisen-sho while card-games are evenly +between kpat and Aiselriot. In desktops it's a tie between +gnome-flashback and mate.</p> <p><strong>Which strategy do you believe is the right one to use to get schools to use free software?</strong></p> -<p>In Germany we have the situation: every school is free to decide -which software they want to use. This decision is influenced by -teachers who learned to use Windows and MS Office. They buy a PC with -Windows preinstalled and an additional testing version of MS -Office. They don't know about the possibility to use Free Software -instead. Another problem are the publisher of school books. They -develop their software, added to the school books, for Windows.</p> +<p>I think it should first start with using specific FOSS apps. in +whatever environment they are. If it's MS-Windows or Mac so be it. +Once they are habitual with the apps. and there is buy-in from the +school management then it could be installed anywhere. Most of the +people now understand the concept of a repository because of the +various online stores so it isn't hard to convince on that front.</p> + +<p>What is harder is having enough people with technical skills and +passion to service them. If you get buy-in from one or two teachers +then ideas like above could also be asked to be done as a project as +well.</p> + +<p>I think where we fall short more than anything is in marketing. For +instance, Debian has this whole range of fonts in its archive but +there isn't even a page where all those different fonts in the La +Ipsum format could be tried out for newcomers.</p> + +<p>One of the issues faced constantly in installations is with updates +and upgrades. People have this myth that each update and upgrade +means the user interface will / has to change. I have seen this +innumerable times. That perhaps is one of the reasons which browsers +like Iceweasel / Firefox change user interfaces so much, not because +it might be needed or be functional but because people believe that +changed user interfaces are better. This, can easily be pointed with +the user interfaces changed with almost every MS-Windows and Mac OS +releases.</p> + +<p>The problems with Debian Edu for deployment are many. The biggest +is the huge gap between what is taught in schools and what Debian Edu +is aimed at. + +<p>Me and my friends did teach on week-ends in a government school for +around 2 years, and +<a href="https://flossexperiences.wordpress.com/2012/10/08/sharings/">gathered +some experience</a> there. Some of the things we learnt/discovered +there was :</p> + +<ol> + + <li>Most of the teachers are very territorial about their subjects + and they do not want you to teach anything out of the + portion/syllabus given.</li> + + <li>They want any activity on the system in accordance to whatever + is in the syllabus.</li> + + <li>There are huge barriers both with the English language and at + times with objects or whatever. An example, let's say in gcompris + you have objects falling down and you have to name them and let's + say the falling object is a hat or a fedora hat, this would not be + as recognizable as say a + <a href="https://en.wikipedia.org/wiki/Puneri_Pagadi">Puneri + Pagdi</a> so there is need to inject local objects, words wherever + possible. Especially for word-games there are so many hindi words + which have become part of english vocabulary (for instance in + parley), those could be made into a hinglish collection or + something but that is something for upstream to do.</li> + +</ol> + + + + + I'm going to the Open Source Developers' Conference Nordic 2015! + http://people.skolelinux.org/pere/blog/I_m_going_to_the_Open_Source_Developers__Conference_Nordic_2015_.html + http://people.skolelinux.org/pere/blog/I_m_going_to_the_Open_Source_Developers__Conference_Nordic_2015_.html + Tue, 7 Apr 2015 10:30:00 +0200 + <p>I am happy to let you all know that I'm going to the <a +href="http://act.osdc.no/osdc2015no/">Open Source Developers' +Conference Nordic 2015</a>!</p> + +<p>It take place Friday 8th to Sunday 10th of May in Oslo next to +where I work, and I finally got around to submitting +<a href="http://act.osdc.no/osdc2015no/talk/6192">a talk proposal for +it</a> (dead link for most people until the talk is accepted).

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>.

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> - - -
