Ved å melde seg +inn i Facebook-samfunnet har de sagt ja til bruksvilkårene og inngått +en antagelig bindende avtale.

Få er klar over at dette innebærer at +e-tjenesten får tilgang til epost sendt til de fleste politiske +partiene på Stortinget.

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.

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.

Here is the recipe if I ever need to do it +again. It all started by me wanting to try the recipe to set up +<a href="https://blog.torproject.org/blog/mission-impossible-hardening-android-security-and-privacy">an +hardened Android installation</a> from the Tor project blog on a +device I had access to. It is a old mobile phone with a broken +microphone The initial idea had been to just +<a href="http://wiki.cyanogenmod.org/w/Install_CM_for_ace">install +CyanogenMod on it</a>, but did not quite find time to start on it +until a few days ago.</p> + +<p>The unlock process is supposed to be simple: (1) Boot into the boot +loader (press volume down and power at the same time), (2) select +'fastboot' before (3) connecting the device via USB to a Linux +machine, (4) request the device identifier token by running 'fastboot +oem get_identifier_token', (5) request the device unlocking key using +the <a href="http://www.htcdev.com/bootloader/">HTC developer web +site</a> and unlock the phone using the key file emailed to you.</p> + +<p>Unfortunately, this only work fi you have hboot version 2.00.0029 +or newer, and the device I was working on had 2.00.0027. This +apparently can be easily fixed by downloading a Windows program and +running it on your Windows machine, if you accept the terms Microsoft +require you to accept to use Windows - which I do not. So I had to +come up with a different approach. I got a lot of help from AndyCap +on #nuug, and would not have been able to get this working without +him.</p> + +<p>First I needed to extract the hboot firmware from +<a href="http://www.htcdev.com/ruu/PD9810000_Ace_Sense30_S_hboot_2.00.0029.exe">the +windows binary for HTC Desire HD</a> downloaded as 'the RUU' from HTC. +For this there is is <a href="https://github.com/kmdm/unruu/">a github +project named unruu</a> using libunshield. The unshield tool did not +recognise the file format, but unruu worked and extracted rom.zip, +containing the new hboot firmware and a text file describing which +devices it would work for.</p> + +<p>Next, I needed to get the new firmware into the device. For this I +followed some instructions +<a href="http://www.htc1guru.com/2013/09/new-ruu-zips-posted/">available +from HTC1Guru.com</a>, and ran these commands as root on a Linux +machine with Debian testing:</p> + +<p><pre> +adb reboot-bootloader +fastboot oem rebootRUU +fastboot flash zip rom.zip +fastboot flash zip rom.zip +fastboot reboot +</pre></p> + +<p>The flash command apparently need to be done twice to take effect, +as the first is just preparations and the second one do the flashing. +The adb command is just to get to the boot loader menu, so turning the +device on while holding volume down and the power button should work +too.</p> + +<p>With the new hboot version in place I could start following the +instructions on the HTC developer web site. I got the device token +like this:</p> + +<p><pre> +fastboot oem get_identifier_token 2>&1 | sed 's/(bootloader) //' +</pre> + +<p>And once I got the unlock code via email, I could use it like +this:</p> + +<p><pre> +fastboot flash unlocktoken Unlock_code.bin +</pre></p> + +<p>And with that final step in place, the phone was unlocked and I +could start stuffing the software of my own choosing into the device. +So far I only inserted a replacement recovery image to wipe the phone +before I start. We will see what happen next. Perhaps I should +install <a href="https://www.debian.org/">Debian</a> on it. :)</p> - Lets make a Norwegian Bokmål edition of The Debian Administrator's Handbook - http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook.html - http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook.html - Sun, 10 Apr 2016 23:20:00 +0200 - <p>During this weekends -<a href="http://www.nuug.no/news/Oslo__Takk_for_feilfiksingsfesten.shtml">bug -squashing party and developer gathering</a>, we decided to do our part -to make sure there are good books about Debian available in Norwegian -Bokmål, and got in touch with the people behind the -<a href="http://debian-handbook.info/">Debian Administrator's Handbook -project</a> to get started.

And sadly the usage is +connected to my land line, thus allowing those controlling the server +to associate it to my home and person.

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> + The new "best" multimedia player in Debian? + http://people.skolelinux.org/pere/blog/The_new__best__multimedia_player_in_Debian_.html + http://people.skolelinux.org/pere/blog/The_new__best__multimedia_player_in_Debian_.html + Mon, 6 Jun 2016 12:50:00 +0200 + <p>When I set out a few weeks ago to figure out +<a href="http://people.skolelinux.org/pere/blog/What_is_the_best_multimedia_player_in_Debian_.html">which +multimedia player in Debian claimed to support most file formats / +MIME types</a>, I was a bit surprised how varied the sets of MIME types +the various players claimed support for. The range was from 55 to 130 +MIME types. I suspect most media formats are supported by all +players, but this is not really reflected in the MimeTypes values in +their desktop files. There are probably also some bogus MIME types +listed, but it is hard to identify which one this is.</p> + +<p>Anyway, in the mean time I got in touch with upstream for some of +the players suggesting to add more MIME types to their desktop files, +and decided to spend some time myself improving the situation for my +favorite media player VLC. The fixes for VLC entered Debian unstable +yesterday. The complete list of MIME types can be seen on the +<a href="https://wiki.debian.org/DebianMultimedia/PlayerSupport">Multimedia +player MIME type support status</a> Debian wiki page.</p> + +<p>The new "best" multimedia player in Debian? It is VLC, followed by +totem, parole, kplayer, gnome-mpv, mpv, smplayer, mplayer-gui and +kmplayer. I am sure some of the other players desktop files support +several of the formats currently listed as working only with vlc, +toten and parole.</p> + +<p>A sad observation is that only 14 MIME types are listed as +supported by all the tested multimedia players in Debian in their +desktop files: audio/mpeg, audio/vnd.rn-realaudio, audio/x-mpegurl, +audio/x-ms-wma, audio/x-scpls, audio/x-wav, video/mp4, video/mpeg, +video/quicktime, video/vnd.rn-realvideo, video/x-matroska, +video/x-ms-asf, video/x-ms-wmv and video/x-msvideo. Personally I find +it sad that video/ogg and video/webm is not supported by all the media +players in Debian. As far as I can tell, all of them can handle both +formats.</p>
