Update

I've put both the MP3 and M3U8 lists in one repo, hosted on Codeberg. It is mirrored to this gist.

This gist will be maintained, and supersedes all IRC and email description of Dioscuri.

Dioscuri, a Gemini-adjacent protocol for interaction

Dioscuri is a protocol intended to supplement Gemini for doing things like performing remote actions or running an application server. It is the POST to Gemini's GET. Dioscuri servers will run on a different port from Gemini servers, so that they do not interfere with each other; it will often be useful to run multiple servers on one host, so no fixed port is specified. The use of client certificates for authorization is strongly recommended, especially if requests are interpreted to affect server-side state.

The name "Dioscuri" is the Latin version of the Classical Greek name Διόσκουροι for the Heavenly Twins, Castor and Pollux/Polydeukes, who were called Gemini in Latin; the constellation is named after them. I say dee-OH-skoo-ree, but Greeks, classicists, and others should feel free to pronounce the name their way.

Great thanks to the members of [#gemini](ir

CBC Radio Stream URLs

Using these URLs, you can listen to CBC radio streams with applications like VLC or Transistor. The files are M3U playlists, so you can use them as-is, edit them to suit your tastes, or use individual URLs.

This playlist contains the .m3u8 URLs from the CBC Listen website, which uses the HLS (HTTP Live Streaming) protocol. The audio stream is broken up into multiple tiny files, which are then fed into the .m3u8 playlist file that delivers them to your computer in the right order. This should work with modern media players.

This legacy playlist uses good old-fashioned MP3 streams found on PublicRadioFan.com. It will work with older programs like Winamp that don't support HLS. I don't know how lo

Reverse Engineering the Apple Airscan / eSCL Protocol

I am not certain of the origins, one person involved in IPP printing claimed it was proprietary of HP , but then again they have their own protocol. AirScan/eSCL is used by other manufacturers too like Xerox, Kyocera, Canon and more. Mopria also seems to claim some responsibility for it but then again it seems not completely. In any case it seems shrouded in such secrecy that to date several years after its implementation, unless someone wants to take it all apart.

I offer this as my contribution. It is not perfect but almost there.

As I began looking for information to make a scanner more compatible, I could only find fragments of information. Even Apple Developer Forums offered zero help. 

Server/Client in eSCL / AirScan:
There is a “server”and a “client” the client can be a desktop computer or mobile device. The server is a scanner or another device configured to emulate a hardware scanner, even a desktop computer. In my case I did this on Linux, so

vi

#!/bin/bash

IN=$1
OUT=$2

true ${SD_PARAMS:="-55dB:d=0.3"};
true ${MIN_FRAGMENT_DURATION:="20"};
export MIN_FRAGMENT_DURATION

if [ -z "$OUT" ]; then

Writing a Discord bot with Discord.py

Hey one, hey all, and welcome to a basic Discord bot writing tutorial. This is a basic tutorial that doesn't cover coding in general, but rather how to work with the Discord.py (v1.0.0a) library and how to write a simple bot with it. General help can be found on the Discord API guild and in the documentation.

This tutorial assumes some prior knowledge of programming, and assumes you already have Python3.5 (and Pip) or later installed and added to your PATH.

With that, let's get to it.
