It had been on my wishlist for a while, because I wanted to +build a Segway like balancing lego robot. I had already built +<a href="http://www.nxtprograms.com/NXT2/segway/">a simple balancing +robot</a> with the kids, using the light/color sensor included in the +NXT kit as the balance sensor, but it was not working very well. It +could balance for a while, but was very sensitive to the light +condition in the room and the reflective properties of the surface and +would fall over after a short while. I wanted something more robust, +and had +<a href="https://www.hitechnic.com/cgi-bin/commerce.cgi?preadd=action&key=NGY1044">the +gyro sensor from HiTechnic</a> I believed would solve it on my +wishlist for some years before it suddenly showed up as a gift from my +loved ones. :)</p> + +<p>Unfortunately I have not had time to sit down and play with it +since then. But that changed some days ago, when I was searching for +lego segway information and came across a recipe from HiTechnic for +building +<a href="http://www.hitechnic.com/blog/gyro-sensor/htway/">the +HTWay</a>, a segway like balancing robot. Build instructions and +<a href="https://www.hitechnic.com/upload/786-HTWayC.nxc">source +code</a> was included, so it was just a question of putting it all +together. And thanks to the great work of many Debian developers, the +compiler needed to build the source for the NXT is already included in +Debian, so I was read to go in less than an hour.

The last few laptops gave me a feeling that -within a year, the life time is just a fraction of what it used to be, -and it slowly become painful to use the laptop without power connected -all the time. Because of this, when I got a new Thinkpad X230 laptop -about two years ago, I decided to monitor its battery state to have -more hard facts when the battery started to fail.</p> - -<img src="http://people.skolelinux.org/pere/blog/images/2015-09-24-laptop-battery-graph.png"/> - -<p>First I tried to find a sensible Debian package to record the -battery status, assuming that this must be a problem already handled -by someone else. I found -<a href="https://tracker.debian.org/pkg/battery-stats">battery-stats</a>, -which collects statistics from the battery, but it was completely -broken. I sent a few suggestions to the maintainer, but decided to -write my own collector as a shell script while I waited for feedback -from him. Via -<a href="http://www.ifweassume.com/2013/08/the-de-evolution-of-my-laptop-battery.html">a -blog post about the battery development on a MacBook Air</a> I also -discovered -<a href="https://github.com/jradavenport/batlog.git">batlog</a>, not -available in Debian.</p> - -<p>I started my collector 2013-07-15, and it has been collecting -battery stats ever since. Now my -/var/log/hjemmenett-battery-status.log file contain around 115,000 -measurements, from the time the battery was working great until now, -when it is unable to charge above 7% of original capacity. My -collector shell script is quite simple and look like this:</p> + Experience and updated recipe for using the Signal app without a mobile phone + http://people.skolelinux.org/pere/blog/Experience_and_updated_recipe_for_using_the_Signal_app_without_a_mobile_phone.html + http://people.skolelinux.org/pere/blog/Experience_and_updated_recipe_for_using_the_Signal_app_without_a_mobile_phone.html + Mon, 10 Oct 2016 11:30:00 +0200 + <p>In July +<a href="http://people.skolelinux.org/pere/blog/How_to_use_the_Signal_app_if_you_only_have_a_land_line__ie_no_mobile_phone_.html">I +wrote how to get the Signal Chrome/Chromium app working</a> without +the ability to receive SMS messages (aka without a cell phone). 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. Signal only work with Chrome/Chromium, as far as I +know, so you need to install it. <pre> -#!/bin/sh -# Inspired by -# http://www.ifweassume.com/2013/08/the-de-evolution-of-my-laptop-battery.html -# See also -# http://blog.sleeplessbeastie.eu/2013/01/02/debian-how-to-monitor-battery-capacity/ -logfile=/var/log/hjemmenett-battery-status.log - -files="manufacturer model_name technology serial_number \ - energy_full energy_full_design energy_now cycle_count status" - -if [ ! -e "$logfile" ] ; then - ( - printf "timestamp," - for f in $files; do - printf "%s," $f - done - echo - ) > "$logfile" -fi - -log_battery() { - # Print complete message in one echo call, to avoid race condition - # when several log processes run in parallel. - msg=$(printf "%s," $(date +%s); \ - for f in $files; do \ - printf "%s," $(cat $f); \ - done) - echo "$msg" -} - -cd /sys/class/power_supply - -for bat in BAT*; do - (cd $bat && log_battery >> "$logfile") -done -</pre> - -<p>The script is called when the power management system detect a -change in the power status (power plug in or out), and when going into -and out of hibernation and suspend. In addition, it collect a value -every 10 minutes.

Note, the phone number you use will be user Signal +username, ie the way others can find you on Signal.</li> + +<li>You can now use Signal to contact others. Note, new contacts do +not show up in the contact list until you restart Signal, and there is +no way to assign names to Contacts. There is also no way to create or +update chat groups. I suspect this is because the web app do not have +a associated contact database.</li> + +</ol> + +<p>I am still a bit uneasy about using Signal, because of the way its +main author moxie0 reject federation and accept dependencies to major +corporations like Google (part of the code is fetched from Google) and +Amazon (the central coordination point is owned by Amazon). See for +example +<a href="https://github.com/LibreSignal/LibreSignal/issues/37">the +LibreSignal issue tracker</a> for a thread documenting the authors +view on these issues.

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>. De som tipser NRK om +nyheter via epost kan dermed gå ut fra at det blir kjent for mange +andre enn NRK at det er gjort.</p> + +<p>Bruk av SMS og telefon registreres av blant annet telefonselskapene +og er tilgjengelig i følge lov og forskrift for blant annet Politi, +NAV og Finanstilsynet, i tillegg til IT-folkene hos telefonselskapene +og deres overordnede. Hvis innringer eller mottaker bruker +smarttelefon vil slik kontakt også gjøres tilgjengelig for ulike +app-leverandører og de som lytter på trafikken mellom telefon og +app-leverandør, alt etter hva som er installert på telefonene som +brukes.</p> + +<p>Brevpost kan virke trygt, og jeg vet ikke hvor mye som registreres +og lagres av postens datastyrte postsorteringssentraler. 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. Rasmussen). Men hvor mange kjenner +en NRK-journalist personlig? Besøk på NRK på Marienlyst krever at en +registrerer sin ankost elektronisk i besøkssystemet. Jeg vet ikke hva +som skjer med det datasettet, men har grunn til å tro at det sendes ut +SMS til den en skal besøke med navnet som er oppgitt. Kanskje greit å +oppgi falskt navn.</p> + +<p>Når så tipset er kommet frem til NRK skal det behandles +redaksjonelt i NRK. Der vet jeg via ulike kilder at de fleste +journalistene bruker lokalt installert programvare, men noen bruker +Google Docs og andre skytjenester i strid med interne retningslinjer +når de skriver. 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>. Jeg vet ikke om den vil kunne snappe opp +dokumenter som lagres på interne filtjenere eller dokumenter som lages +i de interne webbaserte publiseringssystemene, men vet at hva noden +ser etter på nettet kontrolleres av NSM og oppdateres automatisk, slik +at det ikke gir så mye mening å sjekke hva noden ser etter i dag når +det kan endres automatisk i morgen.</p> + +<p>Personlig vet jeg ikke om jeg hadde turt tipse NRK hvis jeg satt på +noe som kunne være en trussel mot den bestående makten i Norge eller +verden. Til det virker det å være for mange åpninger for +utenforstående med andre prioriteter enn NRKs journalistiske fokus. +Og den største truslen for en varsler er jo om metainformasjon kommer +på avveie, dvs. informasjon om at en har vært i kontakt med en +journalist. Det kan være nok til at en kommer i myndighetenes +søkelys, og de færreste har nok operasjonell sikkerhet til at vil tåle +slik flombelysning på sitt privatliv.</p> - In my hand, a pocket book edition of the Norwegian Free Culture book! - http://people.skolelinux.org/pere/blog/In_my_hand__a_pocket_book_edition_of_the_Norwegian_Free_Culture_book_.html - http://people.skolelinux.org/pere/blog/In_my_hand__a_pocket_book_edition_of_the_Norwegian_Free_Culture_book_.html - Wed, 19 Aug 2015 22:10:00 +0200 - <p>Today, finally, my first printed draft edition of the Norwegian -translation of Free Culture I have been working on for the last few -years arrived in the mail. I had to fake a cover to get the interior -printed, and the exterior of the book look awful, but that is -irrelevant at this point. I asked for a printed pocket book version -to get an idea about the font sizes and paper format as well as how -good the figures and images look in print, but also to test what the -pocket book version would look like. After receiving the 500 page -pocket book, it became obvious to me that that pocket book size is too -small for this book. I believe the book is too thick, and several -tables and figures do not look good in the size they get with that -small page sizes. I believe I will go with the 5.5x8.5 inch size -instead. A surprise discovery from the paper version was how bad the -URLs look in print. They are very hard to read in the colophon page. -The URLs are red in the PDF, but light gray on paper. I need to -change the color of links somehow to look better. But there is a -printed book in my hand, and it feels great. :)</p> - -<p>Now I only need to fix the cover, wrap up the postscript with the -store behind the book, and collect the last corrections from the proof -readers before the book is ready for proper printing. Cover artists -willing to work for free and create a Creative Commons licensed vector -file looking similar to the original is most welcome, as my skills as -a graphics designer are mostly missing.</p> + Isenkram, Appstream and udev make life as a LEGO builder easier + http://people.skolelinux.org/pere/blog/Isenkram__Appstream_and_udev_make_life_as_a_LEGO_builder_easier.html + http://people.skolelinux.org/pere/blog/Isenkram__Appstream_and_udev_make_life_as_a_LEGO_builder_easier.html + Fri, 7 Oct 2016 09:50:00 +0200 + <p><a href="http://packages.qa.debian.org/isenkram">The Isenkram +system</a> provide a practical and easy way to figure out which +packages support the hardware in a given machine. 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.

It is lacking a -proper book cover and is not tagged with the correct ISBN number, but -should give me an idea what the finished book will look like.</p> - -<p>Instead of using Lulu, I did consider printing the book using -<a href="http://www.createspace.com/">CreateSpace</a>, but ended up -using Lulu because it had smaller book size options (CreateSpace seem -to lack pocket book with extended distribution). I looked for a -similar service in Norway, but have not seen anything so far. Please -let me know if I am missing out on something here.</p> - -<p>But I still struggle to decide the book size. Should I go for -pocket book (4.25x6.875 inches / 10.8x17.5 cm) with 556 pages, Digest -(5.5x8.5 inches / 14x21.6 cm) with 323 pages or US Trade (6x8 inches / -15.3x22.9 cm) with 280 pages? Fewer pager give a cheaper book, and a -smaller book is easier to carry around. The test book I ordered was -pocket book sized, to give me an idea how well that fit in my hand, -but I suspect I will end up using a digest sized book in the end to -bring the prize down further.</p> - -<p>My biggest challenge at the moment is making nice cover art. My -inkscape skills are not yet up to the task of replicating the original -cover in SVG format. I also need to figure out what to write about -the book on the back (will most likely use the same text as the -description on web based book stores).

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?

So I asked MPEG LA -if their understanding matched that of NRK. As far as I can tell, it -does not.</p> - -<p>I started by asking for more information about the various -licensing classes and what exactly is covered by the "Internet -Broadcast AVC Video" class that NRK pointed me at to explain why NRK -did not need a license for streaming H.264 video: - -<p><blockquote> - -<p>According to -<a href="http://www.mpegla.com/Lists/MPEG%20LA%20News%20List/Attachments/226/n-10-02-02.pdf">a -MPEG LA press release dated 2010-02-02</a>, there is no charge when -using MPEG AVC/H.264 according to the terms of "Internet Broadcast AVC -Video". I am trying to understand exactly what the terms of "Internet -Broadcast AVC Video" is, and wondered if you could help me. What -exactly is covered by these terms, and what is not?</p> - -<p>The only source of more information I have been able to find is a -PDF named -<a href="http://www.mpegla.com/main/programs/avc/Documents/avcweb.pdf">AVC -Patent Portfolio License Briefing</a>, which states this about the -fees:</p> - -<ul> - <li>Where End User pays for AVC Video - <ul> - <li>Subscription (not limited by title) – 100,000 or fewer - subscribers/yr = no royalty; &gt; 100,000 to 250,000 subscribers/yr = - $25,000; &gt;250,000 to 500,000 subscribers/yr = $50,000; &gt;500,000 to - 1M subscribers/yr = $75,000; &gt;1M subscribers/yr = $100,000</li> - - <li>Title-by-Title - 12 minutes or less = no royalty; &gt;12 minutes in - length = lower of (a) 2% or (b) $0.02 per title</li> - </ul></li> - - <li>Where remuneration is from other sources - <ul> - <li>Free Television - (a) one-time $2,500 per transmission encoder or - (b) annual fee starting at $2,500 for &gt; 100,000 HH rising to - maximum $10,000 for &gt;1,000,000 HH</li> - - <li>Internet Broadcast AVC Video (not title-by-title, not subscription) - – no royalty for life of the AVC Patent Portfolio License</li> - </ul></li> -</ul> - -<p>Am I correct in assuming that the four categories listed is the -categories used when selecting licensing terms, and that "Internet -Broadcast AVC Video" is the category for things that do not fall into -one of the other three categories? Can you point me to a good source -explaining what is ment by "title-by-title" and "Free Television" in -the license terms for AVC/H.264?</p> - -<p>Will a web service providing H.264 encoded video content in a -"video on demand" fashing similar to Youtube and Vimeo, where no -subscription is required and no payment is required from end users to -get access to the videos, fall under the terms of the "Internet -Broadcast AVC Video", ie no royalty for life of the AVC Patent -Portfolio license? Does it matter if some users are subscribed to get -access to personalized services?</p> - -<p>Note, this request and all answers will be published on the -Internet.</p> -</blockquote></p> - -<p>The answer came quickly from Benjamin J. Myers, Licensing Associate -with the MPEG LA:</p> - -<p><blockquote> -<p>Thank you for your message and for your interest in MPEG LA. We -appreciate hearing from you and I will be happy to assist you.</p> - -<p>As you are aware, MPEG LA offers our AVC Patent Portfolio License -which provides coverage under patents that are essential for use of -the AVC/H.264 Standard (MPEG-4 Part 10). Specifically, coverage is -provided for end products and video content that make use of AVC/H.264 -technology. Accordingly, the party offering such end products and -video to End Users concludes the AVC License and is responsible for -paying the applicable royalties.</p> - -<p>Regarding Internet Broadcast AVC Video, the AVC License generally -defines such content to be video that is distributed to End Users over -the Internet free-of-charge. Therefore, if a party offers a service -which allows users to upload AVC/H.264 video to its website, and such -AVC Video is delivered to End Users for free, then such video would -receive coverage under the sublicense for Internet Broadcast AVC -Video, which is not subject to any royalties for the life of the AVC -License. This would also apply in the scenario where a user creates a -free online account in order to receive a customized offering of free -AVC Video content. In other words, as long as the End User is given -access to or views AVC Video content at no cost to the End User, then -no royalties would be payable under our AVC License.</p> - -<p>On the other hand, if End Users pay for access to AVC Video for a -specific period of time (e.g., one month, one year, etc.), then such -video would constitute Subscription AVC Video. In cases where AVC -Video is delivered to End Users on a pay-per-view basis, then such -content would constitute Title-by-Title AVC Video. If a party offers -Subscription or Title-by-Title AVC Video to End Users, then they would -be responsible for paying the applicable royalties you noted below.</p> - -<p>Finally, in the case where AVC Video is distributed for free -through an "over-the-air, satellite and/or cable transmission", then -such content would constitute Free Television AVC Video and would be -subject to the applicable royalties.</p> - -<p>For your reference, I have attached -<a href="http://people.skolelinux.org/pere/blog/images/2015-07-07-mpegla.pdf">a -.pdf copy of the AVC License</a>. You will find the relevant -sublicense information regarding AVC Video in Sections 2.2 through -2.5, and the corresponding royalties in Section 3.1.2 through 3.1.4. -You will also find the definitions of Title-by-Title AVC Video, -Subscription AVC Video, Free Television AVC Video, and Internet -Broadcast AVC Video in Section 1 of the License. Please note that the -electronic copy is provided for informational purposes only and cannot -be used for execution.</p> - -<p>I hope the above information is helpful. If you have additional -questions or need further assistance with the AVC License, please feel -free to contact me directly.</p> -</blockquote></p> - -<p>Having a fresh copy of the license text was useful, and knowing -that the definition of Title-by-Title required payment per title made -me aware that my earlier understanding of that phrase had been wrong. -But I still had a few questions:</p> - -<p><blockquote> -<p>I have a small followup question. Would it be possible for me to get -a license with MPEG LA even if there are no royalties to be paid? The -reason I ask, is that some video related products have a copyright -clause limiting their use without a license with MPEG LA. The clauses -typically look similar to this: - -<p><blockquote> - This product is licensed under the AVC patent portfolio license for - the personal and non-commercial use of a consumer to (a) encode - video in compliance with the AVC standard ("AVC video") and/or (b) - decode AVC video that was encoded by a consumer engaged in a - personal and non-commercial activity and/or AVC video that was - obtained from a video provider licensed to provide AVC video. No - license is granted or shall be implied for any other use. additional - information may be obtained from MPEG LA L.L.C. -</blockquote></p> - -<p>It is unclear to me if this clause mean that I need to enter into -an agreement with MPEG LA to use the product in question, even if -there are no royalties to be paid to MPEG LA. I suspect it will -differ depending on the jurisdiction, and mine is Norway. What is -MPEG LAs view on this?</p> -</blockquote></p> - -<p>According to the answer, MPEG LA believe those using such tools for -non-personal or commercial use need a license with them:</p> - -<p><blockquote> - -<p>With regard to the Notice to Customers, I would like to begin by -clarifying that the Notice from Section 7.1 of the AVC License -reads:</p> - -<p>THIS PRODUCT IS LICENSED UNDER THE AVC PATENT PORTFOLIO LICENSE FOR -THE PERSONAL USE OF A CONSUMER OR OTHER USES IN WHICH IT DOES NOT -RECEIVE REMUNERATION TO (i) ENCODE VIDEO IN COMPLIANCE WITH THE AVC -STANDARD ("AVC VIDEO") AND/OR (ii) DECODE AVC VIDEO THAT WAS ENCODED -BY A CONSUMER ENGAGED IN A PERSONAL ACTIVITY AND/OR WAS OBTAINED FROM -A VIDEO PROVIDER LICENSED TO PROVIDE AVC VIDEO. NO LICENSE IS GRANTED -OR SHALL BE IMPLIED FOR ANY OTHER USE. ADDITIONAL INFORMATION MAY BE -OBTAINED FROM MPEG LA, L.L.C. SEE HTTP://WWW.MPEGLA.COM</p> - -<p>The Notice to Customers is intended to inform End Users of the -personal usage rights (for example, to watch video content) included -with the product they purchased, and to encourage any party using the -product for commercial purposes to contact MPEG LA in order to become -licensed for such use (for example, when they use an AVC Product to -deliver Title-by-Title, Subscription, Free Television or Internet -Broadcast AVC Video to End Users, or to re-Sell a third party's AVC -Product as their own branded AVC Product).</p> - -<p>Therefore, if a party is to be licensed for its use of an AVC -Product to Sell AVC Video on a Title-by-Title, Subscription, Free -Television or Internet Broadcast basis, that party would need to -conclude the AVC License, even in the case where no royalties were -payable under the License. On the other hand, if that party (either a -Consumer or business customer) simply uses an AVC Product for their -own internal purposes and not for the commercial purposes referenced -above, then such use would be included in the royalty paid for the AVC -Products by the licensed supplier.</p> - -<p>Finally, I note that our AVC License provides worldwide coverage in -countries that have AVC Patent Portfolio Patents, including -Norway.</p> - -<p>I hope this clarification is helpful. If I may be of any further -assistance, just let me know.</p> -</blockquote></p> - -<p>The mentioning of Norwegian patents made me a bit confused, so I -asked for more information:</p> - -<p><blockquote> - -<p>But one minor question at the end. If I understand you correctly, -you state in the quote above that there are patents in the AVC Patent -Portfolio that are valid in Norway. This make me believe I read the -list available from &lt;URL: -<a href="http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx">http://www.mpegla.com/main/programs/AVC/Pages/PatentList.aspx</a> -&gt; incorrectly, as I believed the "NO" prefix in front of patents -were Norwegian patents, and the only one I could find under Mitsubishi -Electric Corporation expired in 2012. Which patents are you referring -to that are relevant for Norway?</p> - -</blockquote></p> - -<p>Again, the quick answer explained how to read the list of patents -in that list:</p> - -<p><blockquote> - -<p>Your understanding is correct that the last AVC Patent Portfolio -Patent in Norway expired on 21 October 2012. Therefore, where AVC -Video is both made and Sold in Norway after that date, then no -royalties would be payable for such AVC Video under the AVC License. -With that said, our AVC License provides historic coverage for AVC -Products and AVC Video that may have been manufactured or Sold before -the last Norwegian AVC patent expired. I would also like to clarify -that coverage is provided for the country of manufacture and the -country of Sale that has active AVC Patent Portfolio Patents.</p> - -<p>Therefore, if a party offers AVC Products or AVC Video for Sale in -a country with active AVC Patent Portfolio Patents (for example, -Sweden, Denmark, Finland, etc.), then that party would still need -coverage under the AVC License even if such products or video are -initially made in a country without active AVC Patent Portfolio -Patents (for example, Norway). Similarly, a party would need to -conclude the AVC License if they make AVC Products or AVC Video in a -country with active AVC Patent Portfolio Patents, but eventually Sell -such AVC Products or AVC Video in a country without active AVC Patent -Portfolio Patents.</p> -</blockquote></p> - -<p>As far as I understand it, MPEG LA believe anyone using Adobe -Premiere and other video related software with a H.264 distribution -license need a license agreement with MPEG LA to use such tools for -anything non-private or commercial, while it is OK to set up a -Youtube-like service as long as no-one pays to get access to the -content. I still have no clear idea how this applies to Norway, where -none of the patents MPEG LA is licensing are valid. Will the -copyright terms take precedence or can those terms be ignored because -the patents are not valid in Norway?</p> + Coz can help you find bottlenecks in multi-threaded software - nice free software + http://people.skolelinux.org/pere/blog/Coz_can_help_you_find_bottlenecks_in_multi_threaded_software___nice_free_software.html + http://people.skolelinux.org/pere/blog/Coz_can_help_you_find_bottlenecks_in_multi_threaded_software___nice_free_software.html + Thu, 11 Aug 2016 12:00:00 +0200 + <p>This summer, I read a great article +"<a href="https://www.usenix.org/publications/login/summer2016/curtsinger">coz: +This Is the Profiler You're Looking For</a>" in USENIX ;login: about +how to profile multi-threaded programs. It presented a system for +profiling software by running experiences in the running program, +testing how run time performance is affected by "speeding up" parts of +the code to various degrees compared to a normal run. 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). It +can also measure unmodified code by measuring complete the program +runtime and running the program several times instead.</p> + +<p>The project and presentation was so inspiring that I would like to +get the system into Debian. I +<a href="https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=830708">created +a WNPP request for it</a> and contacted upstream to try to make the +system ready for Debian by sending patches. The build process need to +be changed a bit to avoid running 'git clone' to get dependencies, and +to include the JavaScript web page used to visualize the collected +profiling information included in the source package. +But I expect that should work out fairly soon.</p> + +<p>The way the system work is fairly simple. To run an coz experiment +on a binary with debug symbols available, start the program like this: + +<p><blockquote><pre> +coz run --- program-to-run +</pre></blockquote></p> + +<p>This will create a text file profile.coz with the instrumentation +information. To show what part of the code affect the performance +most, use a web browser and either point it to +<a href="http://plasma-umass.github.io/coz/">http://plasma-umass.github.io/coz/</a> +or use the copy from git (in the gh-pages branch). 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. This allow coz to do more +targeted experiments.</p> + +<p>A video published by ACM +<a href="https://www.youtube.com/watch?v=jE0V-p1odPg">presenting the +Coz profiler</a> is available from Youtube.

I wish to -thank every one of these. Several pointed me to the possibility of -fixing my X230, and I am already in the process of getting Lenovo to -do so thanks to the on site, next day support contract covering the -machine. But the battery is almost useless (I expect to replace it -with a non-official battery) and I do not expect the machine to live -for many more years, so it is time to plan its replacement. If I did -not have a support contract, it was suggested to find replacement parts -using <a href="http://www.francecrans.com/">FrancEcrans</a>, but it -might present a language barrier as I do not understand French.</p> - -<p>One tip I got was to use the -<a href="https://skinflint.co.uk/?cat=nb">Skinflint</a> web service to -compare laptop models. It seem to have more models available than -prisjakt.no. Another tip I got from someone I know have similar -keyboard preferences was that the HP EliteBook 840 keyboard is not -very good, and this matches my experience with earlier EliteBook -keyboards I tested. Because of this, I will not consider it any further. - -<p>When I wrote my blog post, I was not aware of Thinkpad X250, the -newest Thinkpad X model. The keyboard reintroduces mouse buttons -(which is missing from the X240), and is working fairly well with -Debian Sid/Unstable according to -<a href="http://www.corsac.net/X250/">Corsac.net</a>. The reports I -got on the keyboard quality are not consistent. Some say the keyboard -is good, others say it is ok, while others say it is not very good. -Those with experience from X41 and and X60 agree that the X250 -keyboard is not as good as those trusty old laptops, and suggest I -keep and fix my X230 instead of upgrading, or get a used X230 to -replace it. I'm also told that the X250 lack leds for caps lock, disk -activity and battery status, which is very convenient on my X230. I'm -also told that the CPU fan is running very often, making it a bit -noisy. In any case, the X250 do not work out of the box with Debian -Stable/Jessie, one of my requirements.</p> - -<p>I have also gotten a few vendor proposals, one was -<a href="http://pro-star.com">Pro-Star</a>, another was -<a href="http://shop.gluglug.org.uk/product/libreboot-x200/">Libreboot</a>. -The latter look very attractive to me.</p> - -<p>Again, thank you all for the very useful feedback. It help a lot -as I keep looking for a replacement.</p> - -<p>Update 2015-07-06: I was recommended to check out the -<a href="">lapstore.de</a> web shop for used laptops. They got several -different -<a href="http://www.lapstore.de/f.php/shop/lapstore/f/411/lang/x/kw/Lenovo_ThinkPad_X_Serie/">old -thinkpad X models</a>, and provide one year warranty.</p> + 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. A bit less +known is the fact that due to the way I created the translations, +using docbook and po4a, I also recreated the English original. And +because I already had created a new the PDF edition, I published it +too. The revenue from the books are sent to the Creative Commons +Corporation. In other words, I do not earn any money from this +project, I just earn the warm fuzzy feeling that the text is available +for a wider audience and more people can learn why the Creative +Commons is needed.</p> + +<p>Today, just for fun, I had a look at the sales number over at +Lulu.com, which take care of payment, printing and shipping. Much to +my surprise, the English edition is selling better than both the +French and Norwegian edition, despite the fact that it has been +available in English since it was first published. In total, 24 paper +books was sold for USD $19.99 between 2016-01-01 and 2016-07-31:</p> + +<table border="0"> +<tr><th>Title / language</th><th>Quantity</th></tr> +<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html">Culture Libre / French</a></td><td align="right">3</td></tr> +<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/fri-kultur/paperback/product-22441576.html">Fri kultur / Norwegian</a></td><td align="right">7</td></tr> +<tr><td><a href="http://www.lulu.com/shop/lawrence-lessig/free-culture/paperback/product-22440520.html">Free Culture / English</a></td><td align="right">14</td></tr> +</table> + +<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>
