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 +<a href="https://minetest.net/">Minetest</a>.</p> + +<p>There is <a href="https://github.com/sprintingkiwi/pycraft_mod">a +Minetest module implementing the same API</a>, making it possible to +use the Python programs coded to talk to Minecraft with Minetest too. +I +<a href="https://ftp-master.debian.org/new/minetest-mod-pycraft_0.20%2Bgit20180331.0376a0a%2Bdfsg-1.html">uploaded +this module</a> 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 +<a href="https://salsa.debian.org/games-team/unfinished/minetest-mod-pycraft">the +packaging rules</a> are currently located under 'unfinished' on +Salsa.</p> + +<p>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.</p> + +<p>I tried to find a way to add the API to the desktop version of +Minecraft, but were unable to find any working recipes.

This new version +include a complete rewrite of the bittorrent related code, which seem +to make the plugin non-blocking. This mean you can actually exit VLC +even when the plugin seem to be unable to get the bittorrent streaming +started. The new version also include support for filtering playlist +by file extension using command line options, if you want to avoid +processing audio, video or images. The package is currently in Debian +unstable, but should be available in Debian testing in two days. To +test it, simply install it like this:</p> + +<p><pre> +apt install vlc-plugin-bittorrent +</pre></p> + +<p>After it is installed, you can try to use it to play a file +downloaded live via bittorrent like this: + +<p><pre> +vlc https://archive.org/download/Glass_201703/Glass_201703_archive.torrent +</pre></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> + + + + + Retten til kontant betaling er en rettighet som må brukes for å beholdes + http://people.skolelinux.org/pere/blog/Retten_til_kontant_betaling_er_en_rettighet_som_m__brukes_for___beholdes.html + http://people.skolelinux.org/pere/blog/Retten_til_kontant_betaling_er_en_rettighet_som_m__brukes_for___beholdes.html + Tue, 11 Dec 2018 10:00:00 +0100 + <p><a href="https://www.fn.no/Om-FN/Avtaler/Menneskerettigheter/FNs-verdenserklaering-om-menneskerettigheter">FNs +menneskerettighetserklæring</a> artikkel 13 første punkt lyder som +følger:</p> + +<p><blockquote> +Enhver har rett til å bevege seg fritt og til fritt å velge +oppholdssted innenfor en stats grenser. +</blockquote></p> + +<p>Det er altså en menneskerett å kunne bevege seg fritt i landet. +For å bevege seg fritt i landet, så må en kunne bevege seg uten å bli +sporet. Det vil i dagens samfunn innebære å bevege seg uten å legge +igjen digitale spor og uten å være radiomerket. Hvis en vet at ens +bevegelser, hvor en befinner seg når, og hvem som befinner seg i +nærheten, blir samlet inn og gjort tilgjengelig for fremmede, det være +seg myndighetene eller private organisasjoner, så kan en ikke lenger +bevege seg fritt. Dette gjør at det er en forutsetning for å ha glede +av retten til å bevege seg fritt i landet at en motstår fristelsen til +å legge igjen digitale spor når en betaler for seg. Rettigheter som +ikke blir brukt, blir fjernet. Den eneste måten i dag å unngå å legge +igjen digitale spor når en betaler for seg, er å betale med kontanter, +samt takke nei til å legge igjen navn og adresse (slik f.eks. Elkjøp +ber om &mdash; jeg sier de kan legge inn «anonym anonym» når +datasystemet deres trenger et navn). Personlig anbefaler jeg å +konsekvent bruke kontant betaling når man beveger seg rundt, for å +bidra til forsvaret av menneskerettighetene i Norge. Kanskje noe også +for deg? Merk at det ikke er tilstrekkelig for å unngå sporing å +betale med kontanter, men det er et lite steg i riktig retning.</p> + +<p>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 +<a href="https://www.dagbladet.no/kultur/kontantlost-diktatur/70543434">kontantløst +diktatur</a> som venter oss hvis mange nok slutter å insistere på å +betale med kontanter.
