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 -<a href="https://www.diyaudioandvideo.com/Tutorial/SpeakerResponseTesting/">Speaker -Testing and Analysis</a> describing how to test speakers, and it listing -several software options, among them -<a href="https://sourceforge.net/projects/audmes/">AUDio MEasurement -System (AUDMES)</a>. 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 -<a href="http://novo.press/understanding-speaker-specifications-and-frequency-response/">Understanding -Speaker Specifications and Frequency Response</a> and an article from -ecoustics on -<a href="https://www.ecoustics.com/articles/understanding-speaker-frequency-response/">Understanding -Speaker Frequency Response</a>, 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.</p> - -<p>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.</p> - -<p>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 -<a href="http://freehearingtestsoftware.com">Free Hearing Test -Software</a>, 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.</p> - -<p>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 -<a href="https://bugs.debian.org/910876">include in Debian</a>? And if -you know of some other free software to measure speakers and amplifier -performance, please let me know.

I decided to wrap it up and make it -<a href="https://tracker.debian.org/pkg/python-rfc3161ng">available in -Debian</a>, and a few days ago it entered Debian unstable and testing.</p> - -<p>Using the library is fairly straight forward. The only slightly -problematic step is to fetch the required certificates to verify the -timestamp. For some services it is straight forward, while for others -I have not yet figured out how to do it.

I've been keeping an eye on virtual -currencies for many years, and it is part of the reason a few months -ago, I started writing a python library for collecting currency -exchange rates and trade on virtual currency exchanges. I decided to -name the end result valutakrambod, which perhaps can be translated to -small currency shop.</p> - -<p>The library uses the tornado python library to handle HTTP and -websocket connections, and provide a asynchronous system for -connecting to and tracking several services. The code is available -from -<a href="http://github.com/petterreinholdtsen/valutakrambod">github</a>.</p> - -</p>There are two example clients of the library. One is very simple and -list every updated buy/sell price received from the various services. -This code is started by running bin/btc-rates and call the client code -in valutakrambod/client.py. The simple client look like this:</p> - -<p><blockquote><pre> -import functools -import tornado.ioloop -import valutakrambod -class SimpleClient(object): - def __init__(self): - self.services = [] - self.streams = [] - pass - def newdata(self, service, pair, changed): - print("%-15s %s-%s: %8.3f %8.3f" % ( - service.servicename(), - pair[0], - pair[1], - service.rates[pair]['ask'], - service.rates[pair]['bid']) - ) - async def refresh(self, service): - await service.fetchRates(service.wantedpairs) - def run(self): - self.ioloop = tornado.ioloop.IOLoop.current() - self.services = valutakrambod.service.knownServices() - for e in self.services: - service = e() - service.subscribe(self.newdata) - stream = service.websocket() - if stream: - self.streams.append(stream) - else: - # Fetch information from non-streaming services immediately - self.ioloop.call_later(len(self.services), - functools.partial(self.refresh, service)) - # as well as regularly - service.periodicUpdate(60) - for stream in self.streams: - stream.connect() - try: - self.ioloop.start() - except KeyboardInterrupt: - print("Interrupted by keyboard, closing all connections.") - pass - for stream in self.streams: - stream.close() -</pre></blockquote></p> - -<p>The library client loops over all known "public" services, -initialises it, subscribes to any updates from the service, checks and -activates websocket streaming if the service provide it, and if no -streaming is supported, fetches information from the service and sets -up a periodic update every 60 seconds. The output from this client -can look like this:</p> - -<p><blockquote><pre> -Bl3p BTC-EUR: 5687.110 5653.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Hitbtc BTC-USD: 6594.560 6593.690 -Hitbtc BTC-USD: 6594.560 6593.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Hitbtc BTC-USD: 6594.570 6593.690 -Bitstamp EUR-USD: 1.159 1.154 -Hitbtc BTC-USD: 6594.570 6593.690 -Hitbtc BTC-USD: 6594.580 6593.690 -Hitbtc BTC-USD: 6594.580 6593.690 -Hitbtc BTC-USD: 6594.580 6593.690 -Bl3p BTC-EUR: 5687.110 5653.690 -Paymium BTC-EUR: 5680.000 5620.240 -</pre></blockquote></p> - -<p>The exchange order book is tracked in addition to the best buy/sell -price, for those that need to know the details.</p> - -<p>The other example client is focusing on providing a curses view -with updated buy/sell prices as soon as they are received from the -services. This code is located in bin/btc-rates-curses and activated -by using the '-c' argument. Without the argument the "curses" output -is printed without using curses, which is useful for debugging. The -curses view look like this:</p> - -<p><blockquote><pre> - Name Pair Bid Ask Spr Ftcd Age - BitcoinsNorway BTCEUR 5591.8400 5711.0800 2.1% 16 nan 60 - Bitfinex BTCEUR 5671.0000 5671.2000 0.0% 16 22 59 - Bitmynt BTCEUR 5580.8000 5807.5200 3.9% 16 41 60 - Bitpay BTCEUR 5663.2700 nan nan% 15 nan 60 - Bitstamp BTCEUR 5664.8400 5676.5300 0.2% 0 1 1 - Bl3p BTCEUR 5653.6900 5684.9400 0.5% 0 nan 19 - Coinbase BTCEUR 5600.8200 5714.9000 2.0% 15 nan nan - Kraken BTCEUR 5670.1000 5670.2000 0.0% 14 17 60 - Paymium BTCEUR 5620.0600 5680.0000 1.1% 1 7515 nan - BitcoinsNorway BTCNOK 52898.9700 54034.6100 2.1% 16 nan 60 - Bitmynt BTCNOK 52960.3200 54031.1900 2.0% 16 41 60 - Bitpay BTCNOK 53477.7833 nan nan% 16 nan 60 - Coinbase BTCNOK 52990.3500 54063.0600 2.0% 15 nan nan - MiraiEx BTCNOK 52856.5300 54100.6000 2.3% 16 nan nan - BitcoinsNorway BTCUSD 6495.5300 6631.5400 2.1% 16 nan 60 - Bitfinex BTCUSD 6590.6000 6590.7000 0.0% 16 23 57 - Bitpay BTCUSD 6564.1300 nan nan% 15 nan 60 - Bitstamp BTCUSD 6561.1400 6565.6200 0.1% 0 2 1 - Coinbase BTCUSD 6504.0600 6635.9700 2.0% 14 nan 117 - Gemini BTCUSD 6567.1300 6573.0700 0.1% 16 89 nan - Hitbtc+BTCUSD 6592.6200 6594.2100 0.0% 0 0 0 - Kraken BTCUSD 6565.2000 6570.9000 0.1% 15 17 58 - Exchangerates EURNOK 9.4665 9.4665 0.0% 16 107789 nan - Norgesbank EURNOK 9.4665 9.4665 0.0% 16 107789 nan - Bitstamp EURUSD 1.1537 1.1593 0.5% 4 5 1 - Exchangerates EURUSD 1.1576 1.1576 0.0% 16 107789 nan - BitcoinsNorway LTCEUR 1.0000 49.0000 98.0% 16 nan nan - BitcoinsNorway LTCNOK 492.4800 503.7500 2.2% 16 nan 60 - BitcoinsNorway LTCUSD 1.0221 49.0000 97.9% 15 nan nan - Norgesbank USDNOK 8.1777 8.1777 0.0% 16 107789 nan -</pre></blockquote></p> - -<p>The code for this client is too complex for a simple blog post, so -you will have to check out the git repository to figure out how it -work.

After searching the -web for API access to the Youtube plugin and testing a bit, I managed -to find a recipe that worked. If you got a kodi instance with its API -available from http://kodihost/jsonrpc, you can try the following to -have check out a nice cover band.</p> - -<p><blockquote><pre>curl --silent --header 'Content-Type: application/json' \ - --data-binary '{ "id": 1, "jsonrpc": "2.0", "method": "Player.Open", - "params": {"item": { "file": - "plugin://plugin.video.youtube/play/?video_id=LuRGVM9O0qg" } } }' \ - http://projector.local/jsonrpc</pre></blockquote></p> - -<p>I've extended kodi-stream program to take a video source as its -first argument. It can now handle direct video links, youtube links -and 'desktop' to stream my desktop to Kodi. It is almost like a -Chromecast. :)</p> + When terms and policy turn users away + http://people.skolelinux.org/pere/blog/When_terms_and_policy_turn_users_away.html + http://people.skolelinux.org/pere/blog/When_terms_and_policy_turn_users_away.html + Sat, 7 Dec 2019 21:15:00 +0100 + <p>When asked to accept terms of use and privacy policies that state +it will to remove rights I otherwise had or accept unreasonable terms +undermining my privacy, I choose away the service. I simply do not +have the conscience to accept terms I have no indention of upholding. +But how are the system and service providers to know how many people +they scared away? Normally I just quietly walk away. But today, I +tried a new approach. I sent the following email (removing the +specifics, as I am not out to take the specific service in question) +to the service provider I decided to not use, to at least give them +one data point on how many users are unhappy with their terms:</p> + +<blockquote> +From: Petter Reinholdtsen +<br>Subject: When terms of use turn users away +<br>To: [contact@some.site] +<br>Date: Sat, 07 Dec 2019 16:30:56 +0100 + +<p>Dear [Site Owner],</p> + +<p>I was eager to test the system, as it seemed like a fun and +interesting application of [some] technology, but after reading the +terms of use and privacy policy on &lt;URL: +https://www.[some.site]/terms-of-use &gt; and &lt;URL: +https://www.[some.site]/privacy-policy &gt; I want you to know that I +decided to turn away. There were several provisions in the terms and +policy turning me off, but the final term that convinced me was being +asked to sign away my right to reverse engineer.</p> + +<p>-- +<br>Happy hacking +<br>Petter Reinholdtsen</p> +</blockquote> + +<p>I do not expect much to come out of it, but sharing it here in case +others want to give something similar a try too. If companies +discover their terms scare away enough people, perhaps they will be +improved...</p> <p>As usual, if you use Bitcoin and want to show your support of my activities, please send Bitcoin donations to my address
