My projector can be controlled via both +a infrared remote controller, and a RS-232 serial line. The vendor of +my projector, <a href="https://www.infocus.com/">InFocus</a>, had been +sensible enough to document the serial protocol in its user manual, so +it is easily available, and I used it some years ago to write +<a href="https://github.com/petterreinholdtsen/infocus-projector-control">a +small script to control the projector</a>. For a while now, I longed +for a setup where the projector was controlled by Kodi, for example in +such a way that when the screen saver went on, the projector was +turned off, and when the screen saver exited, the projector was turned +on again.</p> + +<p>A few days ago, with very good help from parts of my family, I +managed to find a Kodi Add-on for controlling a Epson projector, and +got in touch with its author to see if we could join forces and make a +Add-on with support for several projectors. To my pleasure, he was +positive to the idea, and we set out to add InFocus support to his +add-on, and make the add-on suitable for the official Kodi add-on +repository.</p> + +<p>The Add-on is now working (for me, at least), with a few minor +adjustments. The most important change I do relative to the master +branch in the github repository is embedding the +<a href="https://github.com/pyserial/pyserial">pyserial module</a> in +the add-on. The long term solution is to make a "script" type +pyserial module for Kodi, that can be pulled in as a dependency in +Kodi. But until that in place, I embed it.</p> + +<p>The add-on can be configured to turn on the projector when Kodi +starts, off when Kodi stops as well as turn the projector off when the +screensaver start and on when the screesaver stops. It can also be +told to set the projector source when turning on the projector. + +<p>If this sound interesting to you, check out +<a href="https://github.com/fredrik-eriksson/kodi_projcontrol">the +project github repository</a>. Perhaps you can send patches to +support your projector too? As soon as we find time to wrap up the +latest changes, it should be available for easy installation using any +Kodi instance.</p> + +<p>For future improvements, I would like to add projector model +detection and the ability to adjust the brightness level of the +projector from within Kodi. We also need to figure out how to handle +the cooling period of the projector. My projector refuses to turn on +for 60 seconds after it was turned off. This is not handled well by +the add-on at the moment.</p> + +<p>As usual, if you use Bitcoin and want to show your support of my +activities, please send Bitcoin donations to my address +<b><a href="bitcoin:15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b">15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b</a></b>.</p> - First draft Norwegian Bokmål edition of The Debian Administrator's Handbook now public - http://people.skolelinux.org/pere/blog/First_draft_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook_now_public.html - http://people.skolelinux.org/pere/blog/First_draft_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook_now_public.html - Tue, 30 Aug 2016 10:10:00 +0200 - <p>In April we -<a href="http://people.skolelinux.org/pere/blog/Lets_make_a_Norwegian_Bokm_l_edition_of_The_Debian_Administrator_s_Handbook.html">started -to work</a> on a Norwegian Bokmål edition of the "open access" book on -how to set up and administrate a Debian system.

It 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.

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.

What I find a bit surprising, is how little +criticism Facebook is getting for handing the information over to +Cambridge Analytica and others in the first place. And what about the +people handing their private and personal information to Facebook? +And last, but not least, what about the government offices who are +handing information about the visitors of their web pages to Facebook? +No-one who looked at the terms of use of Facebook should be surprised +that information about peoples interests, political views, personal +lifes and whereabouts would be sold by Facebook.</p> + +<p>What I find to be the real scandal is the fact that Facebook is +selling your personal information, not that one of the buyers used it +in a way Facebook did not approve when exposed. It is well known that +Facebook is selling out their users privacy, but a scandal +nevertheless. Of course the information provided to them by Facebook +would be misused by one of the parties given access to personal +information about the millions of Facebook users. Collected +information will be misused sooner or later. The only way to avoid +such misuse, is to not collect the information in the first place. If +you do not want Facebook to hand out information about yourself for +the use and misuse of its customers, do not give Facebook the +information.</p> + +<p>Personally, I would recommend to completely remove your Facebook +account, and take back some control of your personal information. +<a href="https://www.theguardian.com/technology/2018/mar/19/how-to-protect-your-facebook-privacy-or-delete-yourself-completely">According +to The Guardian</a>, it is a bit hard to find out how to request +account removal (and not just 'disabling').

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> + H, Ap, Frp og Venstre går for DNA-innsamling av hele befolkningen + http://people.skolelinux.org/pere/blog/H__Ap__Frp_og_Venstre_g_r_for_DNA_innsamling_av_hele_befolkningen.html + http://people.skolelinux.org/pere/blog/H__Ap__Frp_og_Venstre_g_r_for_DNA_innsamling_av_hele_befolkningen.html + Wed, 14 Mar 2018 14:15:00 +0100 + <p>I går kom det nok et argument for å holde seg unna det norske +helsevesenet.

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.

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.
