It is +time to share some experiences and provide an updated setup.</p> + +<p>The Signal app have worked fine for several months now, and I use +it regularly to chat with my loved ones. I had a major snag at the +end of my summer vacation, when the the app completely forgot my +setup, identity and keys. The reason behind this major mess was +running out of disk space. To avoid that ever happening again I have +started storing everything in <tt>userdata/</tt> in git, to be able to +roll back to an earlier version if the files are wiped by mistake. I +had to use it once after introducing the git backup. When rolling +back to an earlier version, one need to use the 'reset session' option +in Signal to get going, and notify the people you talk with about the +problem. I assume there is some sequence number tracking in the +protocol to detect rollback attacks. The git repository is rather big +(674 MiB so far), but I have not tried to figure out if some of the +content can be added to a .gitignore file due to lack of spare +time.</p> + +<p>I've also hit the 90 days timeout blocking, and noticed that this +make it impossible to send messages using Signal. I could still +receive them, but had to patch the code with a new timestamp to send. +I believe the timeout is added by the developers to force people to +upgrade to the latest version of the app, even when there is no +protocol changes, to reduce the version skew among the user base and +thus try to keep the number of support requests down.</p> + +<p>Since my original recipe, the Signal source code changed slightly, +making the old patch fail to apply cleanly. Below is an updated +patch, including the shell wrapper I use to start Signal. The +original version required a new user to locate the JavaScript console +and call a function from there. I got help from a friend with more +JavaScript knowledge than me to modify the code to provide a GUI +button instead. This mean that to get started you just need to run +the wrapper and click the 'Register without mobile phone' to get going +now. I've also modified the timeout code to always set it to 90 days +in the future, to avoid having to patch the code regularly.</p> + +<p>So, the updated recipe for Debian Jessie:</p> + +<ol> + +<li>First, install required packages to get the source code and the +browser you need.

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> + NRKs kildevern når NRK-epost deles med utenlands etterretning? + http://people.skolelinux.org/pere/blog/NRKs_kildevern_n_r_NRK_epost_deles_med_utenlands_etterretning_.html + http://people.skolelinux.org/pere/blog/NRKs_kildevern_n_r_NRK_epost_deles_med_utenlands_etterretning_.html + Sat, 8 Oct 2016 08:15:00 +0200 + <p>NRK +<a href="https://nrkbeta.no/2016/09/02/securing-whistleblowers/">lanserte +for noen uker siden</a> en ny +<a href="https://www.nrk.no/varsle/">varslerportal som bruker +SecureDrop til å ta imot tips</a> der det er vesentlig at ingen +utenforstående får vite at NRK er tipset. Det er et langt steg +fremover for NRK, og når en leser bloggposten om hva de har tenkt på +og hvordan løsningen er satt opp virker det som om de har gjort en +grundig jobb der. Men det er ganske mye ekstra jobb å motta tips via +SecureDrop, så varslersiden skriver "Nyhetstips som ikke krever denne +typen ekstra vern vil vi gjerne ha på nrk.no/03030", og 03030-siden +foreslår i tillegg til et webskjema å bruke epost, SMS, telefon, +personlig oppmøte og brevpost. Denne artikkelen handler disse andre +metodene.</p> + +<p>Når en sender epost til en @nrk.no-adresse så vil eposten sendes ut +av landet til datamaskiner kontrollert av Microsoft. En kan sjekke +dette selv ved å slå opp epostleveringsadresse (MX) i DNS. For NRK er +dette i dag "nrk-no.mail.protection.outlook.com". NRK har som en ser +valgt å sette bort epostmottaket sitt til de som står bak outlook.com, +dvs. Microsoft. En kan sjekke hvor nettverkstrafikken tar veien +gjennom Internett til epostmottaket vha. programmet +<tt>traceroute</tt>, og finne ut hvem som eier en Internett-adresse +vha. whois-systemet. Når en gjør dette for epost-trafikk til @nrk.no +ser en at trafikken fra Norge mot nrk-no.mail.protection.outlook.com +går via Sverige mot enten Irland eller Tyskland (det varierer fra gang +til gang og kan endre seg over tid).</p> + +<p>Vi vet fra +<a href="https://no.wikipedia.org/wiki/FRA-loven">introduksjonen av +FRA-loven</a> at IP-trafikk som passerer grensen til Sverige avlyttes +av Försvarets radioanstalt (FRA). Vi vet videre takket være +Snowden-bekreftelsene at trafikk som passerer grensen til +Storbritannia avlyttes av Government Communications Headquarters +(GCHQ). I tillegg er er det nettopp lansert et forslag i Norge om at +forsvarets E-tjeneste skal få avlytte trafikk som krysser grensen til +Norge. Jeg er ikke kjent med dokumentasjon på at Irland og Tyskland +gjør det samme. Poenget er uansett at utenlandsk etterretning har +mulighet til å snappe opp trafikken når en sender epost til @nrk.no. +I tillegg er det selvsagt tilgjengelig for Microsoft som er underlagt USAs +jurisdiksjon og +<a href="https://www.theguardian.com/world/2013/jul/11/microsoft-nsa-collaboration-user-data">samarbeider +med USAs etterretning på flere områder</a>.

Det vil ikke +overraske meg om det lagres hvor i landet hver konvolutt kommer fra og +hvor den er adressert, i hvert fall for en kortere periode. Jeg vet +heller ikke hvem slik informasjon gjøres tilgjengelig for. Det kan +være nok til å ringe inn potensielle kilder når det krysses med hvem +som kjente til aktuell informasjon og hvor de befant seg (tilgjengelig +f.eks. hvis de bærer mobiltelefon eller bor i nærheten).</p> + +<p>Personlig oppmøte hos en NRK-journalist er antagelig det tryggeste, +men en bør passe seg for å bruke NRK-kantina. Der bryter de nemlig +<a href="http://www.lovdata.no/all/hl-19850524-028.html#14">Sentralbanklovens +paragraf 14</a> og nekter folk å betale med kontanter. I stedet +krever de at en varsle sin bankkortutsteder om hvor en befinner seg +ved å bruke bankkort. Banktransaksjoner er tilgjengelig for +bankkortutsteder (det være seg VISA, Mastercard, Nets og/eller en +bank) i tillegg til politiet og i hvert fall tidligere med Se & Hør +(via utro tjenere, slik det ble avslørt etter utgivelsen av boken +«Livet, det forbannede» av Ken B.

Hvordan vet en hvem det gjelder? Ikke vet jeg, men +det kan være greit å spørre for å sjekke at journalisten har tenkt på +problemstillingen, før en gir et tips. Og hvis tipset omtales internt +på epost, er det jo grunn til å tro at også intern eposten vil deles +med Microsoft og utenlands etterretning, slik tidligere nevnt, men det +kan hende at det holdes internt i NRKs interne MS Exchange-løsning. +Men Microsoft ønsker å få alle Exchange-kunder over "i skyen" (eller +andre folks datamaskiner, som det jo innebærer), så jeg vet ikke hvor +lenge det i så fall vil vare.</p> + +<p>I tillegg vet en jo at +<a href="https://www.nrk.no/ytring/elektronisk-kildevern-i-nrk-1.11941196">NRK +har valgt å gi nasjonal sikkerhetsmyndighet (NSM) tilgang til å se på +intern og ekstern Internett-trafikk</a> hos NRK ved oppsett av såkalte +VDI-noder, på tross av +<a href="https://www.nrk.no/ytring/bekymring-for-nrks-kildevern-1.11941584">protester +fra NRKs journalistlag</a>.

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. Men NRK bruker jo tilsynelatende disse verktøyene uten patentavtale -med MPEG LA.</p> - -<p>I følge forfatteren av Open Broadcast Encoder finnes det to typer -H.264-relaterte avtaler en kan få 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. Han sa videre at -NRK trenger en slik avtale hvis NRK tilbyr H.264-kodet video til -sluttbrukere.

The command line +tool <tt>isenkram-lookup</tt> and the tasksel options provide a +convenient way to list and install packages relevant for the current +hardware during system installation, both user space packages and +firmware packages. The GUI background daemon on the other hand provide +a pop-up proposing to install packages when a new dongle is inserted +while using the computer. For example, if you plug in a smart card +reader, the system will ask if you want to install <tt>pcscd</tt> if +that package isn't already installed, and if you plug in a USB video +camera the system will ask if you want to install <tt>cheese</tt> if +cheese is currently missing. This already work just fine.</p> + +<p>But Isenkram depend on a database mapping from hardware IDs to +package names. When I started no such database existed in Debian, so +I made my own data set and included it with the isenkram package and +made isenkram fetch the latest version of this database from git using +http. This way the isenkram users would get updated package proposals +as soon as I learned more about hardware related packages.</p> + +<p>The hardware is identified using modalias strings. The modalias +design is from the Linux kernel where most hardware descriptors are +made available as a strings that can be matched using filename style +globbing. It handle USB, PCI, DMI and a lot of other hardware related +identifiers.</p> + +<p>The downside to the Isenkram specific database is that there is no +information about relevant distribution / Debian version, making +isenkram propose obsolete packages too. But along came AppStream, a +cross distribution mechanism to store and collect metadata about +software packages. When I heard about the proposal, I contacted the +people involved and suggested to add a hardware matching rule using +modalias strings in the specification, to be able to use AppStream for +mapping hardware to packages. This idea was accepted and AppStream is +now a great way for a package to announce the hardware it support in a +distribution neutral way. I wrote +<a href="http://people.skolelinux.org/pere/blog/Using_appstream_with_isenkram_to_install_hardware_related_packages_in_Debian.html">a +recipe on how to add such meta-information</a> in a blog post last +December. If you have a hardware related package in Debian, please +announce the relevant hardware IDs using AppStream.</p> + +<p>In Debian, almost all packages that can talk to a LEGO Mindestorms +RCX or NXT unit, announce this support using AppStream. The effect is +that when you insert such LEGO robot controller into your Debian +machine, Isenkram will propose to install the packages needed to get +it working. The intention is that this should allow the local user to +start programming his robot controller right away without having to +guess what packages to use or which permissions to fix.</p> + +<p>But when I sat down with my son the other day to program our NXT +unit using his Debian Stretch computer, I discovered something +annoying. The local console user (ie my son) did not get access to +the USB device for programming the unit. This used to work, but no +longer in Jessie and Stretch. After some investigation and asking +around on #debian-devel, I discovered that this was because udev had +changed the mechanism used to grant access to local devices. The +ConsoleKit mechanism from <tt>/lib/udev/rules.d/70-udev-acl.rules</tt> +no longer applied, because LDAP users no longer was added to the +plugdev group during login. Michael Biebl told me that this method +was obsolete and the new method used ACLs instead. This was good +news, as the plugdev mechanism is a mess when using a remote user +directory like LDAP. Using ACLs would make sure a user lost device +access when she logged out, even if the user left behind a background +process which would retain the plugdev membership with the ConsoleKit +setup. Armed with this knowledge I moved on to fix the access problem +for the LEGO Mindstorms related packages.</p> + +<p>The new system uses a udev tag, 'uaccess'. It can either be +applied directly for a device, or is applied in +/lib/udev/rules.d/70-uaccess.rules for classes of devices. As the +LEGO Mindstorms udev rules did not have a class, I decided to add the +tag directly in the udev rules files included in the packages. Here +is one example. For the nqc C compiler for the RCX, the +<tt>/lib/udev/rules.d/60-nqc.rules</tt> file now look like this: + +<p><pre> +SUBSYSTEM=="usb", ACTION=="add", ATTR{idVendor}=="0694", ATTR{idProduct}=="0001", \ + SYMLINK+="rcx-%k", TAG+="uaccess" +</pre></p> + +<p>The key part is the 'TAG+="uaccess"' at the end. I suspect all +packages using plugdev in their /lib/udev/rules.d/ files should be +changed to use this tag (either directly or indirectly via +<tt>70-uaccess.rules</tt>). Perhaps a lintian check should be created +to detect this?</p> + +<p>I've been unable to find good documentation on the uaccess feature. +It is unclear to me if the uaccess tag is an internal implementation +detail like the udev-acl tag used by +<tt>/lib/udev/rules.d/70-udev-acl.rules</tt>. If it is, I guess the +indirect method is the preferred way. Michael +<a href="https://github.com/systemd/systemd/issues/4288">asked for more +documentation from the systemd project</a> and I hope it will make +this clearer. For now I use the generic classes when they exist and +is already handled by <tt>70-uaccess.rules</tt>, and add the tag +directly if no such class exist.</p> + +<p>To learn more about the isenkram system, please check out +<a href="http://people.skolelinux.org/pere/blog/tags/isenkram/">my +blog posts tagged isenkram</a>.</p> + +<p>To help out making life for LEGO constructors in Debian easier, +please join us on our IRC channel +<a href="irc://irc.debian.org/%23debian-lego">#debian-lego</a> and join +the <a href="https://alioth.debian.org/projects/debian-lego/">Debian +LEGO team</a> in the Alioth project we created yesterday.

Det sies ikke direkte i -hverken proposisjon, innstilling eller vedtak, men fremgår når en ser -på indirekte formuleringer.</p> - -<p>I -<a href="https://www.regjeringen.no/nb/dokumenter/prop.-66-l-2014-2015/id2399703/">stortingsproposisjon -66</a>, avsnitt 6.3.5 (Avgivelse av biometriske personopplysninger) -står det<p> - -<p><blockquote> - - <p>Departementet foreslår at både ansiktsfoto og fingeravtrykk skal - kunne opptas og lagres som identifikasjonsdata i de nasjonale - ID-kortene, på samme måte som i passene. Lovforslaget er derfor - utformet i tråd med passloven § 6 annet ledd, som fastslår at det - til bruk for senere verifisering eller kontroll av passinnehaverens - identitet kan innhentes og lagres i passet biometrisk - personinformasjon i form av ansiktsfoto og fingeravtrykk (to - fingre). Dagens ordning med lagring av ansiktsfoto og fingeravtrykk - i et kontaktløst smartkort i passet er basert på internasjonale - standarder. Fingeravtrykkene i nasjonalt ID-kort vil bli beskyttet - på samme måte som fingeravtrykkene i passene.</p> - - <p>[...]</p> - - <p>For norske forhold understreker departementet at innføring av - nasjonale ID-kort sammen med innføring av nye systemer for sikrere - utstedelse og kontroll av pass og relaterte dokumenter gir mulighet - til å utforme ordningen slik at den best mulig møter utfordringene - forbundet med identitetskriminalitet. Det tilsier at fingeravtrykk - opptas og lagres i alle nasjonale ID-kort.</p> -</blockquote></p> - -<p>Departementet sier altså at sin anbefaling er at fingeravtrykk skal -opptas og lagres i alle nasjonale ID-kort. 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> + Aftenposten-redaktøren med lua i hånda + http://people.skolelinux.org/pere/blog/Aftenposten_redakt_ren_med_lua_i_h_nda.html + http://people.skolelinux.org/pere/blog/Aftenposten_redakt_ren_med_lua_i_h_nda.html + Fri, 9 Sep 2016 11:30:00 +0200 + <p>En av dagens nyheter er at Aftenpostens redaktør Espen Egil Hansen +bruker +<a href="https://www.nrk.no/kultur/aftenposten-brukar-heile-forsida-pa-facebook-kritikk-1.13126918">forsiden +av papiravisen på et åpent brev til Facebooks sjef Mark Zuckerberg om +Facebooks fjerning av bilder, tekster og sider de ikke liker</a>. Det +må være uvant for redaktøren i avisen Aftenposten å stå med lua i +handa og håpe på å bli hørt. Spesielt siden Aftenposten har vært med +på å gi Facebook makten de nå demonstrerer at de har. Ved å melde seg +inn i Facebook-samfunnet har de sagt ja til bruksvilkårene og inngått +en antagelig bindende avtale. Kanskje de skulle lest og vurdert +vilkårene litt nærmere før de sa ja, i stedet for å klage over at +reglende de har valgt å akseptere blir fulgt? Personlig synes jeg +vilkårene er uakseptable og det ville ikke falle meg inn å gå inn på +en avtale med slike vilkår. I tillegg til uakseptable vilkår er det +mange andre grunner til å unngå Facebook. Du kan finne en solid +gjennomgang av flere slike argumenter hos +<a href="https://stallman.org/facebook.html">Richard Stallmans side om +Facebook</a>. + +<p>Jeg håper flere norske redaktører på samme vis må stå med lua i +hånden inntil de forstår at de selv er med på å føre samfunnet på +ville veier ved å omfavne Facebook slik de gjør når de omtaler og +løfter frem saker fra Facebook, og tar i bruk Facebook som +distribusjonskanal for sine nyheter. De bidrar til +overvåkningssamfunnet og raderer ut lesernes privatsfære når de lenker +til Facebook på sine sider, og låser seg selv inne i en omgivelse der +det er Facebook, og ikke redaktøren, som sitter med makta.</p> + +<p>Men det vil nok ta tid, i et Norge der de fleste nettredaktører +<a href="http://people.skolelinux.org/pere/blog/Snurpenot_overv_kning_av_sensitiv_personinformasjon.html">deler +sine leseres personopplysinger med utenlands etterretning</a>.</p> + +<p>For øvrig burde varsleren Edward Snowden få politisk asyl i +Norge.</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> + E-tjenesten ber om innsyn i eposten til partiene på Stortinget + http://people.skolelinux.org/pere/blog/E_tjenesten_ber_om_innsyn_i_eposten_til_partiene_p__Stortinget.html + http://people.skolelinux.org/pere/blog/E_tjenesten_ber_om_innsyn_i_eposten_til_partiene_p__Stortinget.html + Tue, 6 Sep 2016 23:00:00 +0200 + <p>I helga kom det et hårreisende forslag fra Lysne II-utvalget satt +ned av Forsvarsdepartementet. Lysne II-utvalget var bedt om å vurdere +ønskelista til Forsvarets etterretningstjeneste (e-tjenesten), og har +kommet med +<a href="http://www.aftenposten.no/norge/Utvalg-sier-ja-til-at-E-tjenesten-far-overvake-innholdet-i-all-internett--og-telefontrafikk-som-krysser-riksgrensen-603232b.html">forslag +om at e-tjenesten skal få lov til a avlytte all Internett-trafikk</a> +som passerer Norges grenser. Få er klar over at dette innebærer at +e-tjenesten får tilgang til epost sendt til de fleste politiske +partiene på Stortinget. Regjeringspartiet Høyre (@hoyre.no), +støttepartiene Venstre (@venstre.no) og Kristelig Folkeparti (@krf.no) +samt Sosialistisk Ventreparti (@sv.no) og Miljøpartiet de grønne +(@mdg.no) har nemlig alle valgt å ta imot eposten sin via utenlandske +tjenester. Det betyr at hvis noen sender epost til noen med en slik +adresse vil innholdet i eposten, om dette forslaget blir vedtatt, gjøres +tilgjengelig for e-tjenesten. Venstre, Sosialistisk Ventreparti og +Miljøpartiet De Grønne har valgt å motta sin epost hos Google, +Kristelig Folkeparti har valgt å motta sin epost hos Microsoft, og +Høyre har valgt å motta sin epost hos Comendo med mottak i Danmark og +Irland. Kun Arbeiderpartiet og Fremskrittspartiet har valgt å motta +eposten sin i Norge, hos henholdsvis Intility AS og Telecomputing +AS.</p> + +<p>Konsekvensen er at epost inn og ut av de politiske organisasjonene, +til og fra partimedlemmer og partiets tillitsvalgte vil gjøres +tilgjengelig for e-tjenesten for analyse og sortering. Jeg mistenker +at kunnskapen som slik blir tilgjengelig vil være nyttig hvis en +ønsker å vite hvilke argumenter som treffer publikum når en ønsker å +påvirke Stortingets representanter.</p + +<p>Ved hjelp av MX-oppslag i DNS for epost-domene, tilhørende +whois-oppslag av IP-adressene og traceroute for å se hvorvidt +trafikken går via utlandet kan enhver få bekreftet at epost sendt til +de omtalte partiene vil gjøres tilgjengelig for forsvarets +etterretningstjeneste hvis forslaget blir vedtatt. En kan også bruke +den kjekke nett-tjenesten <a href="http://ipinfo.io/">ipinfo.io</a> +for å få en ide om hvor i verden en IP-adresse hører til.</p> + +<p>På den positive siden vil forslaget gjøre at enda flere blir +motivert til å ta grep for å bruke +<a href="https://www.torproject.org/">Tor</a> og krypterte +kommunikasjonsløsninger for å kommunisere med sine kjære, for å sikre +at privatsfæren vernes. Selv bruker jeg blant annet +<a href="https://www.freedomboxfoundation.org/">FreedomBox</a> og +<a href="https://whispersystems.org/">Signal</a> til slikt.

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> + First draft Norwegian Bokmål edition of The Debian Administrator's Handbook now public + http://people.skolelinux.org/pere/blog/First_draft_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook_now_public.html + http://people.skolelinux.org/pere/blog/First_draft_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook_now_public.html + Tue, 30 Aug 2016 10:10:00 +0200 + <p>In April we +<a href="http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook.html">started +to work</a> on a Norwegian Bokmål edition of the "open access" book on +how to set up and administrate a Debian system.

It does this by +slowing down parallel threads while the "faster up" code is running +and measure how this affect processing time. The processing time is +measured using probes inserted into the code, either using progress +counters (COZ_PROGRESS) or as latency meters (COZ_BEGIN/COZ_END).

Check out this web +site to have a look at several example profiling runs and get an idea what the end result from the profile runs look like. To make the +profiling more useful you include &lt;coz.h&gt; and insert the +COZ_PROGRESS or COZ_BEGIN and COZ_END at appropriate places in the +code, rebuild and run the profiler.

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 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>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>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>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>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>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> + Sales number for the Free Culture translation, first half of 2016 + http://people.skolelinux.org/pere/blog/Sales_number_for_the_Free_Culture_translation__first_half_of_2016.html + http://people.skolelinux.org/pere/blog/Sales_number_for_the_Free_Culture_translation__first_half_of_2016.html + Fri, 5 Aug 2016 22:45:00 +0200 + <p>As my regular readers probably remember, the last year I published +a French and Norwegian translation of the classic +<a href="http://www.free-culture.cc/">Free Culture book</a> by the +founder of the Creative Commons movement, Lawrence Lessig.

I hope to see you there.</p> - -<p>Check out <a href="http://act.osdc.no/osdc2015no/talks">the talks -submitted and accepted so far</a>.</p> - - - - - Proof reading the Norwegian translation of Free Culture by Lessig - http://people.skolelinux.org/pere/blog/Proof_reading_the_Norwegian_translation_of_Free_Culture_by_Lessig.html - http://people.skolelinux.org/pere/blog/Proof_reading_the_Norwegian_translation_of_Free_Culture_by_Lessig.html - Sat, 4 Apr 2015 09:30:00 +0200 - <p>During eastern I had some time to continue working on the Norwegian -<a href="http://www.docbook.org/">docbook</a> version of the 2004 book -<a href="http://free-culture.cc/">Free Culture</a> by Lawrence Lessig. -At the moment I am proof reading the finished text, looking for typos, -inconsistent wordings and sentences that do not flow as they should. -I'm more than two thirds done with the text, and welcome others to -check the text up to chapter 13. The current status is available on the -<a href="https://github.com/petterreinholdtsen/free-culture-lessig">github</a> -project pages. You can also check out the -<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.pdf?raw=true">PDF</a>, -<a href="https://github.com/petterreinholdtsen/free-culture-lessig/blob/master/archive/freeculture.nb.epub?raw=true">EPUB</a> -and HTML version available in the -<a href="https://github.com/petterreinholdtsen/free-culture-lessig/tree/master/archive">archive -directory</a>.</p> - -<p>Please report typos, bugs and improvements to the github project if -you find any.</p> +<p>The books are available both from Lulu.com and from large book +stores like Amazon and Barnes&Noble. Most revenue, around $10 per +book, is sent to the Creative Commons project when the book is sold +directly by Lulu.com. The other channels give less revenue. The +summary from Lulu tell me 10 books was sold via the Amazon channel, 10 +via Ingram (what is this?) and 4 directly by Lulu. And Lulu.com tells +me that the revenue sent so far this year is USD $101.42. No idea +what kind of sales numbers to expect, so I do not know if that is a +good amount of sales for a 10 year old book or not. But it make me +happy that the buyers find the book, and I hope they enjoy reading it +as much as I did.</p> + +<p>The ebook edition is available for free from +<a href="https://github.com/petterreinholdtsen/free-culture-lessig">Github</a>.</p> + +<p>If you would like to translate and publish the book in your native +language, I would be happy to help make it happen. Please get in +touch.</p>
