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.

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> +apt install git tor chromium +git clone https://github.com/WhisperSystems/Signal-Desktop.git +</pre></li> + +<li>Modify the source code using command listed in the the patch +block below.</li> + +<li>Start Signal using the run-signal-app wrapper (for example using +<tt>`pwd`/run-signal-app</tt>). + +<li>Click on the 'Register without mobile phone', will in a phone +number you can receive calls to the next minute, receive the +verification code and enter it into the form field and press +'Register'. 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. But the network effect is strong in this case, +and several of the people I want to communicate with already use +Signal. Perhaps we can all move to <a href="https://ring.cx/">Ring</a> +once it <a href="https://bugs.debian.org/830265">work on my +laptop</a>?

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> - Ny utgave (v2.2) av den frie norske stavekontrollen gitt ut - http://people.skolelinux.org/pere/blog/Ny_utgave__v2_2__av_den_frie_norske_stavekontrollen_gitt_ut.html - http://people.skolelinux.org/pere/blog/Ny_utgave__v2_2__av_den_frie_norske_stavekontrollen_gitt_ut.html - Fri, 15 Apr 2016 21:20:00 +0200 - <p>I dag tok jeg mot til meg og pakket sammen en ny versjon av den -frie norske stavekontrollen, ca. tre og et halvt år etter forrige -gang.

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.

Stone when I came across an article by Jon -Schwarz on The Intercept -<a href="https://theintercept.com/2015/05/07/new-documentary-legacy-f-stone/">about -his extraordinary contribution to investigative journalism in -USA</a>. The article is about a new documentary in two parts -(<a href="https://vimeo.com/123974841">part one is 12 minutes</a> and -<a href="https://vimeo.com/123974842">part two is 30 minutes</a>), and -I found both truly fascinating. It is amazing what he was able to -find by digging up public sources and government papers. He -documented lots of government abuse and cover ups, and I find -<a href="http://www.ifstone.org/weekly.php">his weekly news letters</a> -inspiring to read even today.</p> - -<p><blockquote> -All governments are run by liars and nothing they say should be believed. -<br>- I. F. Stone -</blockquote></p> - -<p>His starting point was that reporters should not assume governments -and corporations are telling the truth, but verify all their claims as -much as possible. I wonder how many Norwegian reporters can be said -to follow the principles of I. F. Stone. They are definitely in short -supply.

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> - A French paperback edition of the book Free Culture by Lawrence Lessig is now available - http://people.skolelinux.org/pere/blog/A_French_paperback_edition_of_the_book_Free_Culture_by_Lawrence_Lessig_is_now_available.html - http://people.skolelinux.org/pere/blog/A_French_paperback_edition_of_the_book_Free_Culture_by_Lawrence_Lessig_is_now_available.html - Tue, 12 Apr 2016 10:40:00 +0200 - <p>I'm happy to report that -<a href="http://www.lulu.com/shop/lawrence-lessig/culture-libre/paperback/product-22645082.html">the -French paperback edition</a> of -<a href="https://github.com/petterreinholdtsen/free-culture-lessig">my -project to translate</a> the <a href="http://free-culture.cc/">Free -Culture</a> book by Lawrence Lessig is now available for sale on -Lulu.com.

I use -ZFS myself at home, but did not really expect many others to do so. -But I might be wrong.</p> - -<p>According to -<a href="https://qa.debian.org/popcon.php?package=spl-linux">the popcon -results for spl-linux</a>, there are 1019 Debian installations, or -0.53% of the population, with the package installed. As far as I know -the only use of the spl-linux package is as a support library for ZFS -on Linux, so I use it here as proxy for measuring the number of ZFS -installation on Linux in Debian. In the kFreeBSD variant of Debian -the ZFS feature is already available, and there -<a href="https://qa.debian.org/popcon.php?package=zfsutils">the popcon -results for zfsutils</a> show 1625 Debian installations or 0.84% of -the population. So I guess I am not alone in using ZFS on Debian.</p> - -<p>But even though the Debian project leader Lucas Nussbaum -<a href="https://lists.debian.org/debian-devel-announce/2015/04/msg00006.html">announced -in April 2015</a> that the legal obstacles blocking ZFS on Debian were -cleared, the package is still not in Debian. The package is again in -the NEW queue. Several uploads have been rejected so far because the -debian/copyright file was incomplete or wrong, but there is no reason -to give up. The current status can be seen on -<a href="https://qa.debian.org/developer.php?login=pkg-zfsonlinux-devel@lists.alioth.debian.org">the -team status page</a>, and -<a href="http://anonscm.debian.org/gitweb/?p=pkg-zfsonlinux/zfs.git">the -source code</a> is available on Alioth.</p> - -<p>As I want ZFS to be included in next version of Debian to make sure -my home server can function in the future using only official Debian -packages, and the current blocker is to get the debian/copyright file -accepted by the FTP masters in Debian, I decided a while back to try -to help out the team. This was the background for my blog post about -<a href="http://people.skolelinux.org/pere/blog/Creating__updating_and_checking_debian_copyright_semi_automatically.html">creating, -updating and checking debian/copyright semi-automatically</a>, and I -used the techniques I explored there to try to find any errors in the -copyright file. It is not very easy to check every one of the around -2000 files in the source package, but I hope we this time got it -right. If you want to help out, check out the git source and try to -find missing entries in the debian/copyright file.</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. There is also a paper +from the 25th Symposium on Operating Systems Principles available +titled +<a href="https://www.usenix.org/conference/atc16/technical-sessions/presentation/curtsinger">Coz: +finding code that counts with causal profiling</a>.</p> + +<p><a href="https://github.com/plasma-umass/coz">The source code</a> +for Coz is available from github.

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.
