My movie playing setup involve Kodi, -OpenELEC (probably soon to be -replaced with LibreELEC) and an -Infocus IN76 video projector. My projector can be controlled via both -a infrared remote controller, and a RS-232 serial line. The vendor of -my projector, InFocus, 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 -small script to control the projector. 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.
- -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.
- -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 -pyserial module 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.
- -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. - -
If this sound interesting to you, check out -the -project github repository. 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.
- -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.

+ +The layered video playout server created by Sveriges Television, +CasparCG Server, entered Debian +today. This completes many months of work to get the source ready to +go into Debian. The first upload to the Debian NEW queue happened a +month ago, but the work upstream to prepare it for Debian started more +than two and a half month ago. So far +the +casparcg-server package is only available for amd64, but I hope +this can be improved. The package is in contrib because it depend on +the non-free fdk-aac +library. The Debian package lack support for streaming web pages +because Debian is missing CEF, Chromium Embedded Framework. CEF is +wanted by several packages in Debian. But because the Chromium source +is not available as a build +dependency, it is not yet possible to upload CEF to Debian. I +hope this will change in the future.
+ +The reason I got involved is that +the Norwegian open channel +Frikanalen is starting to use CasparCG for our HD playout, and I +would like to have all the free software tools we use to run the TV +channel available as packages from the Debian project. The last +remaining piece in the puzzle is Open Broadcast Encoder, but it depend +on quite a lot of patched libraries which would have to be included in +Debian first.
I VHS-kassettenes -tid var det rett frem å ta vare på et TV-program en ønsket å kunne se -senere, uten å være avhengig av at programmet ble sendt på nytt. -Kanskje ønsket en å se programmet på hytten der det ikke var -TV-signal, eller av andre grunner ha det tilgjengelig for fremtidig -fornøyelse. Dette er blitt vanskeligere med introduksjon av -digital-TV og webstreaming, der opptak til harddisk er utenfor de -flestes kontroll hvis de bruker ufri programvare og bokser kontrollert -av andre. Men for NRK her i Norge, finnes det heldigvis flere fri -programvare-alternativer, som jeg har -skrevet -om -før. -Så lenge kilden for nedlastingen er lovlig lagt ut på nett (hvilket -jeg antar NRK gjør), så er slik lagring til privat bruk også lovlig i -Norge.

+ +A fun way to learn how to program +Python is to follow the +instructions in the book +"Learn to program +with Minecraft", which introduces programming in Python to people +who like to play with Minecraft. The book uses a Python library to +talk to a TCP/IP socket with an API accepting build instructions and +providing information about the current players in a Minecraft world. +The TCP/IP API was first created for the Minecraft implementation for +Raspberry Pi, and has since been ported to some server versions of +Minecraft. The book contain recipes for those using Windows, MacOSX +and Raspian. But a little known fact is that you can follow the same +recipes using the free software construction game +Minetest.
+ +There is a +Minetest module implementing the same API, making it possible to +use the Python programs coded to talk to Minecraft with Minetest too. +I +uploaded +this module to Debian two weeks ago, and as soon as it clears the +FTP masters NEW queue, learning to program Python with Minetest on +Debian will be a simple 'apt install' away. The Debian package is +maintained as part of the Debian Games team, and +the +packaging rules are currently located under 'unfinished' on +Salsa.
+ +You will most likely need to install several of the Minetest +modules in Debian for the examples included with the library to work +well, as there are several blocks used by the example scripts that are +provided via modules in Minetest. Without the required blocks, a +simple stone block is used instead. My initial testing with a analog +clock did not get gold arms as instructed in the python library, but +instead used stone arms.
+ +I tried to find a way to add the API to the desktop version of +Minecraft, but were unable to find any working recipes. The +recipes +I found are only +working with a standalone Minecraft server setup. Are there any +options to use with the normal desktop version?

+ +A few hours ago, a new and improved version (2.4) of +the VLC +bittorrent plugin was uploaded to Debian. This new version +include a complete rewrite of the bittorrent related code, which seem +to make the plugin non-blocking.

Brevpost er beskyttet av straffelovens bestemmelse som gjør det -kriminelt å åpne andres brev. Dette følger av (ny) straffelovs -§ 205 -(Krenkelse av retten til privat kommunikasjon), som sier at «Med -bot eller fengsel inntil 2 år straffes den som uberettiget ... c) -åpner brev eller annen lukket skriftlig meddelelse som er adressert -til en annen, eller på annen måte skaffer seg uberettiget tilgang til -innholdet.» Dette gjelder såvel postbud som alle andre som har -befatning med brevet etter at avsender har befatning med et lukket -brev. Tilsvarende står også tidligere utgaver av den norske -straffeloven.
- -Når en registrerer seg på usikre digitale postkasseløsningene, som -f.eks. Digipost og e-Boks, og slik tar disse i bruk, så gir en de som -står bak løsningene tillatelse til å åpne sine brev. Dette er -nødvendig for at innholdet i digital post skal kunne vises frem til -mottaker via tjenestens websider. Dermed gjelder ikke straffelovens -paragraf om forbud mot å åpne brev, da tilgangen ikke lenger er -uberettiget. En gir altså fremmede tilgang til å lese sin -korrespondanse. I tillegg vil bruk av slike usikre digitale -postbokser føre til at det blir registrert når du leser brevene, hvor -du befinner deg (vha. tilkoblingens IP-adresse), hvilket utstyr du -bruker og en rekke annen personlig informasjon som ikke er -tilgjengelig når papirpost brukes. Jeg foretrekker at det er -lovmessig beskyttelse av min korrespondanse, som jo inneholder privat -og personlig informasjon. Det bidrar til litt bedre vern av personlig -integritet i dagens norske samfunn.
+ +FNs +menneskerettighetserklæring artikkel 13 første punkt lyder som +følger:
+ ++Enhver har rett til å bevege seg fritt og til fritt å velge +oppholdssted innenfor en stats grenser. ++ +
Det er altsÃ¥ en menneskerett Ã¥ kunne bevege seg fritt i landet. +For Ã¥ bevege seg fritt i landet, sÃ¥ mÃ¥ en kunne bevege seg uten Ã¥ bli +sporet. Det vil i dagens samfunn innebære Ã¥ bevege seg uten Ã¥ legge +igjen digitale spor og uten Ã¥ være radiomerket. Hvis en vet at ens +bevegelser, hvor en befinner seg nÃ¥r, og hvem som befinner seg i +nærheten, blir samlet inn og gjort tilgjengelig for fremmede, det være +seg myndighetene eller private organisasjoner, sÃ¥ kan en ikke lenger +bevege seg fritt. Dette gjør at det er en forutsetning for Ã¥ ha glede +av retten til Ã¥ bevege seg fritt i landet at en motstÃ¥r fristelsen til +Ã¥ legge igjen digitale spor nÃ¥r en betaler for seg. Rettigheter som +ikke blir brukt, blir fjernet. Den eneste mÃ¥ten i dag Ã¥ unngÃ¥ Ã¥ legge +igjen digitale spor nÃ¥r en betaler for seg, er Ã¥ betale med kontanter, +samt takke nei til Ã¥ legge igjen navn og adresse (slik f.eks. Elkjøp +ber om — jeg sier de kan legge inn «anonym anonym» nÃ¥r +datasystemet deres trenger et navn). Personlig anbefaler jeg Ã¥ +konsekvent bruke kontant betaling nÃ¥r man beveger seg rundt, for Ã¥ +bidra til forsvaret av menneskerettighetene i Norge. Kanskje noe ogsÃ¥ +for deg? Merk at det ikke er tilstrekkelig for Ã¥ unngÃ¥ sporing Ã¥ +betale med kontanter, men det er et lite steg i riktig retning.
+ +Det er flere andre argumenter i tillegg til +menneskerettighetsargumentet for å bruke kontanter. I går hadde +Dagbladet en utmerket kommentar av sin journalist John Olav Egeland om +hvilket +kontantløst +diktatur som venter oss hvis mange nok slutter å insistere på å +betale med kontanter. Jeg anbefaler deg å lese den.

The leaders of the worlds have started to congratulate the -re-elected Russian head of state, and this causes some criticism. I -am though a little fascinated by a comment from USA senator John McCain, -sited -by The Hill and others: - -
-- -"An American president does not lead the Free World by -congratulating dictators on winning sham elections."
-
While I totally agree with the senator here, the way the quote is -phrased make me suspect that he is unaware of the simple fact that USA -have not lead the Free World since at least before its government -kidnapped a -completely innocent Canadian citizen in transit on his way home to -Canada via John F. Kennedy International Airport in September 2002 and -sent him to be tortured in Syria for a year.
+ +Yesterday, I had the pleasure of watching on Frikanalen the OWASP +talk by Scott Helme titled +"What Weâve Learned From +Billions of Security Reports". I had not heard of the +Content +Security Policy standard nor its ability to "call home" when a +browser detect a policy breach (I do not follow web page design +development much these days), and found the talk very illuminating.
+ +The mechanism allow a web site owner to use HTTP headers to tell +visitors web browser which sources (internal and external) are allowed to +be used on the web site. Thus it become possible to enforce a "only +local content" policy despite web designers urge to fetch programs +from random sites on the Internet, like the one +enabling +the attack reported by Scott Helme earlier this year.
+ +Using CSP seem like an obvious thing for a site admin to implement +to take some control over the information leak that occur when +external sources are used to render web pages, it is a mystery more +sites are not using CSP? It is being +standardized under W3C these +days, and is supposed by most web browsers
+ +I managed to find a +Django middleware for implementing CSP and was happy to discover +it was already in Debian. I plan to use it to add CSP support to the +Frikanalen web site soon.

So, Cambridge Analytica is getting some well deserved criticism for -(mis)using information it got from Facebook about 50 million people, -mostly in the USA. 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.
- -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.
- -Personally, I would recommend to completely remove your Facebook -account, and take back some control of your personal information. -According -to The Guardian, it is a bit hard to find out how to request -account removal (and not just 'disabling'). You need to -visit -a specific Facebook page and click on 'let us know' on that page -to get to the -real account deletion screen. Perhaps something to consider? I -would not trust the information to really be deleted (who knows, -perhaps NSA, GCHQ and FRA already got a copy), but it might reduce the -exposure a bit.
- -If you want to learn more about the capabilities of Cambridge -Analytica, I recommend to see the video recording of the one hour talk -Paul-Olivier Dehaye gave to NUUG last april about - -Data collection, psychometric profiling and their impact on -politics.

+ +If you read my blog regularly, you probably know I am involved in +running and developing the Norwegian +TV channel Frikanalen.

The last few days I have updated the code +to add more features. A +new +and improved version 0.0.3 Frikanalen addon was just made +available via the Kodi repositories. This new version include a +option to browse videos by category, as well as free text search +in the video archive. It will now also show the video duration in the +video lists, which were missing earlier. A new and experimental +link to the HD video stream currently being worked on is provided, for +those that want to see what the CasparCG +output look like. The alternative is the SD video stream, generated +using MLT. CasparCG is controlled by our +mltplayout +server which instead of talking to mlt is giving PLAY instructions +to the CasparCG server when it is time to start a new program.
+ +By now, you are probably wondering what kind of content is being +played on the channel. These days, it is filled with technical +presentations like those from NUUG, +Debconf, Makercon, and TED, +but there are also some periods with +EMPT TV and +P7. + +

The first -proof reading is almost done, and only the second and third proof -reading remains. We will also need to translate the 14 figures and -create a book cover. Once it is done we will publish the book on -paper, as well as in PDF, ePub and possibly Mobi formats.
- -The book itself originates as a manuscript on Google Docs, is -downloaded as ODT from there and converted to Markdown using pandoc. -The Markdown is modified by a script before is converted to DocBook -using pandoc. The DocBook is modified again using a script before it -is used to create a Gettext POT file for translators.

+ +My current home stereo is a patchwork of various pieces I got on +flee markeds over the years. It is amazing what kind of equipment +show up there. I've been wondering for a while if it was possible to +measure how well this equipment is working together, and decided to +see how far I could get using free software. After trawling the web I +came across an article from DIY Audio and Video on +Speaker +Testing and Analysis describing how to test speakers, and it listing +several software options, among them +AUDio MEasurement +System (AUDMES). It is the only free software system I could find +focusing on measuring speakers and audio frequency response. In the +process I also found an interesting article from NOVO on +Understanding +Speaker Specifications and Frequency Response and an article from +ecoustics on +Understanding +Speaker Frequency Response, with a lot of information on what to +look for and how to interpret the graphs. Armed with this knowledge, +I set out to measure the state of my speakers.
+ +The first hurdle was that AUDMES hadn't seen a commit for 10 years +and did not build with current compilers and libraries. I got in +touch with its author, who no longer was spending time on the program +but gave me write access to the subversion repository on Sourceforge. +The end result is that now the code build on Linux and is capable of +saving and loading the collected frequency response data in CSV +format. The application is quite nice and flexible, and I was able to +select the input and output audio interfaces independently. This made +it possible to use a USB mixer as the input source, while sending +output via my laptop headphone connection. I lacked the hardware and +cabling to figure out a different way to get independent cabling to +speakers and microphone.
+ +Using this setup I could see how a large range of high frequencies +apparently were not making it out of my speakers. The picture show +the frequency response measurement of one of the speakers. Note the +frequency lines seem to be slightly misaligned, compared to the CSV +output from the program. I can not hear several of these are high +frequencies, according to measurement from +Free Hearing Test +Software, an freeware system to measure your hearing (still +looking for a free software alternative), so I do not know if they are +coming out out the speakers. I thus do not quite know how to figure +out if the missing frequencies is a problem with the microphone, the +amplifier or the speakers, but I managed to rule out the audio card in my +PC by measuring my Bose noise canceling headset using its own +microphone. This setup was able to see the high frequency tones, so +the problem with my stereo had to be in the amplifier or speakers.
+ +Anyway, to try to role out one factor I ended up picking up a new +set of speakers at a flee marked, and these work a lot better than the +old speakers, so I guess the microphone and amplifier is OK. If you +need to measure your own speakers, check out AUDMES. If more people +get involved, perhaps the project could become good enough to +include in Debian? And if +you know of some other free software to measure speakers and amplifier +performance, please let me know. I am aware of the freeware option +REW, but I want something +that can be developed also when the vendor looses interest.

+ +Bittorrent is as far as I know, currently the most efficient way to +distribute content on the Internet. It is used all by all sorts of +content providers, from national TV stations like +NRK, Linux distributors like +Debian and +Ubuntu, and of course the +Internet archive. + +
Almost a month ago +a new +package adding Bittorrent support to VLC became available in +Debian testing and unstable. To test it, simply install it like +this:
+ ++apt install vlc-plugin-bittorrent ++ +
Since the plugin was made available for the first time in Debian, +several improvements have been made to it. In version 2.2-4, now +available in both testing and unstable, a desktop file is provided to +teach browsers to start VLC when the user click on torrent files or +magnet links. The last part is thanks to me finally understanding +what the strange x-scheme-handler style MIME types in desktop files +are used for. By adding x-scheme-handler/magnet to the MimeType entry +in the desktop file, at least the browsers Firefox and Chromium will +suggest to start VLC when selecting a magnet URI on a web page. The +end result is that now, with the plugin installed in Buster and Sid, +one can visit any +Internet +Archive page with movies using a web browser and click on the +torrent link to start streaming the movie.
+ +Note, there is still some misfeatures in the plugin. One is the +fact that it will hang and +block VLC +from exiting until the torrent streaming starts. Another is the +fact that it +will pick +and play a random file in a multi file torrent. This is not +always the video file you want. Combined with the first it can be a +bit hard to get the video streaming going. But when it work, it seem +to do a good job.
+ +For the Debian packaging, I would love to find a good way to test +if the plugin work with VLC using autopkgtest. I tried, but do not +know enough of the inner workings of VLC to get it working. For now +the autopkgtest script is only checking if the .so file was +successfully loaded by VLC. If you have any suggestions, please +submit a patch to the Debian bug tracking system.
