- <description><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>

- <description><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>

- <description><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. Ingen av
-dem er optimale, men de fungerer ganske bra allerede og øker kostnaden
-for dem som ønsker å invadere mitt privatliv.</p>
-
-<p>For øvrig burde varsleren Edward Snowden få politisk asyl i
-Norge.</p>

-to work</a> on a Norwegian Bokmål edition of the "open access" book on
-how to set up and administrate a Debian system. Today I am happy to
-report that the first draft is now publicly available. You can find
-it on <a href="https://debian-handbook.info/get/">get the Debian
-Administrator's Handbook page</a> (under Other languages). The first
-eight chapters have a first draft translation, and we are working on
-proofreading the content. If you want to help out, please start
-contributing using
-<a href="https://hosted.weblate.org/projects/debian-handbook/">the
-hosted weblate project page</a>, and get in touch using
-<a href="http://lists.alioth.debian.org/mailman/listinfo/debian-handbook-translators">the
-translators mailing list</a>. Please also check out
-<a href="https://debian-handbook.info/contribute/">the instructions for
-contributors</a>. A good way to contribute is to proofread the text
-and update weblate if you find errors.</p>
-
-<p>Our goal is still to make the Norwegian book available on paper as well as
-electronic form.</p>

- <description><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. It will only build with clang
-because it uses a
-<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55606">C++
-feature missing in GCC</a>, but I've submitted
-<a href="https://github.com/plasma-umass/coz/pull/67">a patch to solve
-it</a> and hope it will be included in the upstream source soon.</p>
-
-<p>Please get in touch if you, like me, would like to see this piece
-of software in Debian. I would very much like some help with the
-packaging effort, as I lack the in depth knowledge on how to package
-C++ libraries.</p>

- <title>Sales number for the Free Culture translation, first half of 2016</title>

- <description><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>

- <description><p>For mange år siden leste jeg en klassisk tekst som gjorde såpass
-inntrykk på meg at jeg husker den fortsatt, flere år senere, og bruker
-argumentene fra den stadig vekk. Teksten var «The Relativity of
-Wrong» som Isaac Asimov publiserte i Skeptical Inquirer i 1989. Den
-gir litt perspektiv rundt formidlingen av vitenskapelige resultater.
-Jeg har hatt lyst til å kunne dele den også med folk som ikke
-behersker engelsk så godt, som barn og noen av mine eldre slektninger,
-og har savnet å ha den tilgjengelig på norsk. For to uker siden tok
-jeg meg sammen og kontaktet Asbjørn Dyrendal i foreningen Skepsis om
-de var interessert i å publisere en norsk utgave på bloggen sin, og da
-han var positiv tok jeg kontakt med Skeptical Inquirer og spurte om
-det var greit for dem. I løpet av noen dager fikk vi tilbakemelding
-fra Barry Karr hos The Skeptical Inquirer som hadde sjekket og fått OK
-fra Robyn Asimov som representerte arvingene i Asmiov-familien og gikk
-igang med oversettingen.</p>
-
-<p>Resultatet, <a href="http://www.skepsis.no/?p=1617">«Relativt
-feil»</a>, ble publisert på skepsis-bloggen for noen minutter siden.
-Jeg anbefaler deg på det varmeste å lese denne teksten og dele den med
-dine venner.</p>
-
-<p>For å håndtere oversettelsen og sikre at original og oversettelse
-var i sync brukte vi git, po4a, GNU make og Transifex. Det hele
-fungerte utmerket og gjorde det enkelt å dele tekstene og jobbe sammen
-om finpuss på formuleringene. Hadde hosted.weblate.org latt meg
-opprette nye prosjekter selv i stedet for å måtte kontakte
-administratoren der, så hadde jeg brukt weblate i stedet.</p>
