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> - Detect OOXML files with undefined behaviour? - http://people.skolelinux.org/pere/blog/Detect_OOXML_files_with_undefined_behaviour_.html - http://people.skolelinux.org/pere/blog/Detect_OOXML_files_with_undefined_behaviour_.html - Tue, 21 Feb 2017 00:20:00 +0100 - <p>I just noticed -<a href="http://www.arkivrad.no/aktuelt/riksarkivarens-forskrift-pa-horing">the -new Norwegian proposal for archiving rules in the goverment</a> list -<a href="http://www.ecma-international.org/publications/standards/Ecma-376.htm">ECMA-376</a> -/ ISO/IEC 29500 (aka OOXML) as valid formats to put in long term -storage.

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').

This will -generate a set of new files, one file per component type per year for -all components expiring more than two years in the past. The vevent, -vtodo and vjournal entries are handled by the script.

It is a system to look up the hardware present on or -connected to the current system, and map the hardware to Debian -packages. It can either be done using the tools in isenkram-cli or -using the user space daemon in the isenkram package. The latter will -notify you, when inserting new hardware, about what packages to -install to get the dongle working.
