  32         <p>It would come as no surprise to anyone that I am interested in
  33 bitcoins and virtual currencies.  I've been keeping an eye on virtual
  34 currencies for many years, and it is part of the reason a few months
  35 ago, I started writing a python library for collecting currency
  36 exchange rates and trade on virtual currency exchanges.  I decided to
  37 name the end result valutakrambod, which perhaps can be translated to
  38 small currency shop.</p>
  39
  40 <p>The library uses the tornado python library to handle HTTP and
  41 websocket connections, and provide a asynchronous system for
  42 connecting to and tracking several services.  The code is available
  43 from
  44 <a href="http://github.com/petterreinholdtsen/valutakrambod">github</a>.</p>
  45
  46 </p>There are two example clients of the library.  One is very simple and
  47 list every updated buy/sell price received from the various services.
  48 This code is started by running bin/btc-rates and call the client code
  49 in valutakrambod/client.py.  The simple client look like this:</p>
  50
  51 <p><blockquote><pre>
  52 import functools
  53 import tornado.ioloop
  54 import valutakrambod
  55 class SimpleClient(object):
  56     def __init__(self):
  57         self.services = []
  58         self.streams = []
  59         pass
  60     def newdata(self, service, pair, changed):
  61         print("%-15s %s-%s: %8.3f %8.3f" % (
  62             service.servicename(),
  63             pair[0],
  64             pair[1],
  65             service.rates[pair]['ask'],
  66             service.rates[pair]['bid'])
  67         )
  68     async def refresh(self, service):
  69         await service.fetchRates(service.wantedpairs)
  70     def run(self):
  71         self.ioloop = tornado.ioloop.IOLoop.current()
  72         self.services = valutakrambod.service.knownServices()
  73         for e in self.services:
  74             service = e()
  75             service.subscribe(self.newdata)
  76             stream = service.websocket()
  77             if stream:
  78                 self.streams.append(stream)
  79             else:
  80                 # Fetch information from non-streaming services immediately
  81                 self.ioloop.call_later(len(self.services),
  82                                        functools.partial(self.refresh, service))
  83                 # as well as regularly
  84                 service.periodicUpdate(60)
  85         for stream in self.streams:
  86             stream.connect()
  87         try:
  88             self.ioloop.start()
  89         except KeyboardInterrupt:
  90             print("Interrupted by keyboard, closing all connections.")
  91             pass
  92         for stream in self.streams:
  93             stream.close()
  94 </pre></blockquote></p>
  95
  96 <p>The library client loops over all known "public" services,
  97 initialises it, subscribes to any updates from the service, checks and
  98 activates websocket streaming if the service provide it, and if no
  99 streaming is supported, fetches information from the service and sets
 100 up a periodic update every 60 seconds.  The output from this client
 101 can look like this:</p>
 102
 103 <p><blockquote><pre>

 117 Paymium         BTC-EUR: 5680.000 5620.240
 118 </pre></blockquote></p>
 119
 120 <p>The exchange order book is tracked in addition to the best buy/sell
 121 price, for those that need to know the details.</p>
 122
 123 <p>The other example client is focusing on providing a curses view
 124 with updated buy/sell prices as soon as they are received from the
 125 services.  This code is located in bin/btc-rates-curses and activated
 126 by using the '-c' argument.  Without the argument the "curses" output
 127 is printed without using curses, which is useful for debugging.  The
 128 curses view look like this:</p>

 163
 164 <p>The code for this client is too complex for a simple blog post, so
 165 you will have to check out the git repository to figure out how it
 166 work.  What I can tell is how the three last numbers on each line
 167 should be interpreted.  The first is how many seconds ago information
 168 was received from the service.  The second is how long ago, according
 169 to the service, the provided information was updated.  The last is an
 170 estimate on how often the buy/sell values change.</p>
 171
 172 <p>If you find this library useful, or would like to improve it, I
 173 would love to hear from you.  Note that for some of the services I've
 174 implemented a trading API.  It might be the topic of a future blog
 175 post.</p>

 200         <p>Back in February, I got curious to see
 201 <a href="http://people.skolelinux.org/pere/blog/Using_VLC_to_stream_bittorrent_sources.html">if
 202 VLC now supported Bittorrent streaming</a>.  It did not, despite the
 203 fact that the idea and code to handle such streaming had been floating
 204 around for years.  I did however find
 205 <a href="https://github.com/johang/vlc-bittorrent">a standalone plugin
 206 for VLC</a> to do it, and half a year later I decided to wrap up the
 207 plugin and get it into Debian.  I uploaded it to NEW a few days ago,
 208 and am very happy to report that it
 209 <a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">entered
 210 Debian</a> a few hours ago, and should be available in Debian/Unstable
 211 tomorrow, and Debian/Testing in a few days.</p>
 212
 213 <p>With the vlc-plugin-bittorrent package installed you should be able
 214 to stream videos using a simple call to</p>
 215
 216 <p><blockquote><pre>
 217 vlc https://archive.org/download/TheGoat/TheGoat_archive.torrent
 218 </pre></blockquote></p>
 219
 220 </p>It can handle magnet links too.  Now if only native vlc had
 221 bittorrent support.  Then a lot more would be helping each other to
 222 share public domain and creative commons movies.  The plugin need some
 223 stability work with seeking and picking the right file in a torrent
 224 with many files, but is already usable.  Please note that the plugin
 225 is not removing downloaded files when vlc is stopped, so it can fill
 226 up your disk if you are not careful.  Have fun. :)</p>
 227
 228 <p>I would love to get help maintaining this package.  Get in touch if
 229 you are interested.</p>

 254         <p>I continue to explore my Kodi installation, and today I wanted to
 255 tell it to play a youtube URL I received in a chat, without having to
 256 insert search terms using the on-screen keyboard.  After searching the
 257 web for API access to the Youtube plugin and testing a bit, I managed
 258 to find a recipe that worked.  If you got a kodi instance with its API
 259 available from http://kodihost/jsonrpc, you can try the following to
 260 have check out a nice cover band.</p>
 261
 262 <p><blockquote><pre>curl --silent --header 'Content-Type: application/json' \
 263   --data-binary '{ "id": 1, "jsonrpc": "2.0", "method": "Player.Open",
 264   "params": {"item": { "file":
 265   "plugin://plugin.video.youtube/play/?video_id=LuRGVM9O0qg" } } }' \
 266   http://projector.local/jsonrpc</pre></blockquote></p>
 267
 268 <p>I've extended kodi-stream program to take a video source as its
 269 first argument.  It can now handle direct video links, youtube links
 270 and 'desktop' to stream my desktop to Kodi.  It is almost like a
 271 Chromecast. :)</p>
