- <div class="date"> 8th October 2018</div>
- <div class="body"><p>I have earlier covered the basics of trusted timestamping using the
-'openssl ts' client. See blog post for
-<a href="http://people.skolelinux.org/pere/blog/Public_Trusted_Timestamping_services_for_everyone.html">2014</a>,
-<a href="http://people.skolelinux.org/pere/blog/syslog_trusted_timestamp___chain_of_trusted_timestamps_for_your_syslog.html">2016</a>
-and
-<a href="http://people.skolelinux.org/pere/blog/Idea_for_storing_trusted_timestamps_in_a_Noark_5_archive.html">2017</a>
-for those stories. But some times I want to integrate the timestamping
-in other code, and recently I needed to integrate it into Python.
-After searching a bit, I found
-<a href="https://dev.entrouvert.org/projects/python-rfc3161">the
-rfc3161 library</a> which seemed like a good fit, but I soon
-discovered it only worked for python version 2, and I needed something
-that work with python version 3. Luckily I next came across
-<a href="https://github.com/trbs/rfc3161ng/">the rfc3161ng library</a>,
-a fork of the original rfc3161 library. Not only is it working with
-python 3, it have fixed a few of the bugs in the original library, and
-it has an active maintainer. 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. Here is a small standalone
-code example based on of the integration tests in the library code:</p>
-
-<pre>
-#!/usr/bin/python3

-"""
-
-Python 3 script demonstrating how to use the rfc3161ng module to
-get trusted timestamps.

-The license of this code is the same as the license of the rfc3161ng
-library, ie MIT/BSD.

- <div class="date"> 4th October 2018</div>
- <div class="body"><p>A few days, I rescued a Windows victim over to Debian. To try to
-rescue the remains, I helped set up automatic sync with Google Drive.
-I did not find any sensible Debian package handling this
-automatically, so I rebuild the grive2 source from
-<a href="http://www.webupd8.org/">the Ubuntu UPD8 PPA</a> to do the
-task and added a autostart desktop entry and a small shell script to
-run in the background while the user is logged in to do the sync.
-Here is a sketch of the setup for future reference.</p>
-
-<p>I first created <tt>~/googledrive</tt>, entered the directory and
-ran '<tt>grive -a</tt>' to authenticate the machine/user. Next, I
-created a autostart hook in <tt>~/.config/autostart/grive.desktop</tt>
-to start the sync when the user log in:</p>
-
-<p><blockquote><pre>
-[Desktop Entry]
-Name=Google drive autosync
-Type=Application
-Exec=/home/user/bin/grive-sync
-</pre></blockquote></p>
-
-<p>Finally, I wrote the <tt>~/bin/grive-sync</tt> script to sync
-~/googledrive/ with the files in Google Drive.</p>
-
-<p><blockquote><pre>
-#!/bin/sh
-set -e
-cd ~/
-cleanup() {
- if [ "$syncpid" ] ; then
- kill $syncpid
- fi
-}
-trap cleanup EXIT INT QUIT
-/usr/lib/grive/grive-sync.sh listen googledrive 2>&1 | sed "s%^%$0:%" &
-syncpdi=$!
-while true; do
- if ! xhost >/dev/null 2>&1 ; then
- echo "no DISPLAY, exiting as the user probably logged out"
- exit 1
- fi
- if [ ! -e /run/user/1000/grive-sync.sh_googledrive ] ; then
- /usr/lib/grive/grive-sync.sh sync googledrive
- fi
- sleep 300
-done 2>&1 | sed "s%^%$0:%"

- <div class="date">29th September 2018</div>
- <div class="body"><p>It would come as no surprise to anyone that I am interested in
-bitcoins and virtual currencies. 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

-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>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. What I can tell is how the three last numbers on each line
-should be interpreted. The first is how many seconds ago information
-was received from the service. The second is how long ago, according
-to the service, the provided information was updated. The last is an
-estimate on how often the buy/sell values change.</p>
-
-<p>If you find this library useful, or would like to improve it, I
-would love to hear from you. Note that for some of the services I've
-implemented a trading API. It might be the topic of a future blog

-VLC now supported Bittorrent streaming</a>. It did not, despite the
-fact that the idea and code to handle such streaming had been floating

-<a href="https://github.com/johang/vlc-bittorrent">a standalone plugin
-for VLC</a> to do it, and half a year later I decided to wrap up the

-and am very happy to report that it
-<a href="https://tracker.debian.org/pkg/vlc-plugin-bittorrent">entered

-vlc https://archive.org/download/TheGoat/TheGoat_archive.torrent
-</pre></blockquote></p>
-
-</p>It can handle magnet links too. Now if only native vlc had
-bittorrent support. Then a lot more would be helping each other to
-share public domain and creative commons movies. The plugin need some
-stability work with seeking and picking the right file in a torrent
-with many files, but is already usable. Please note that the plugin
-is not removing downloaded files when vlc is stopped, so it can fill
-up your disk if you are not careful. Have fun. :)</p>

- <div class="date">13th August 2018</div>
- <div class="body"><p>A few days ago, I wondered if there are any privacy respecting
-health monitors and/or fitness trackers available for sale these days.
-I would like to buy one, but do not want to share my personal data
-with strangers, nor be forced to have a mobile phone to get data out
-of the unit. I've received some ideas, and would like to share them
-with you.
-
-One interesting data point was a pointer to a Free Software app for
-Android named
-<a href="https://github.com/Freeyourgadget/Gadgetbridge/">Gadgetbridge</a>.
-It provide cloudless collection and storing of data from a variety of
-trackers. Its
-<a href="https://github.com/Freeyourgadget/Gadgetbridge/#supported-devices">list
-of supported devices</a> is a good indicator for units where the
-protocol is fairly open, as it is obviously being handled by Free
-Software. Other units are reportedly encrypting the collected
-information with their own public key, making sure only the vendor
-cloud service is able to extract data from the unit. The people
-contacting me about Gadgetbirde said they were using
-<a href="https://us.amazfit.com/shop/bip?variant=336750">Amazfit
-Bip</a> and
-<a href="http://www.xiaomimi6phone.com/xiaomi-mi-band-3-features-release-date-rumors/">Xiaomi
-Band 3</a>.</p>
-
-<p>I also got a suggestion to look at some of the units from Garmin.
-I was told their GPS watches can be connected via USB and show up as a
-USB storage device with
-<a href="https://www.gpsbabel.org/htmldoc-development/fmt_garmin_fit.html">Garmin
-FIT files</a> containing the collected measurements. While
-proprietary, FIT files apparently can be read at least by
-<a href="https://www.gpsbabel.org">GPSBabel</a> and the
-<a href="https://apps.nextcloud.com/apps/gpxpod">GpxPod</a> Nextcloud
-app. It is unclear to me if they can read step count and heart rate
-data. The person I talked to was using a
-<a href="https://buy.garmin.com/en-US/US/p/564291">Garmin Forerunner
-935</a>, which is a fairly expensive unit. I doubt it is worth it for
-a unit where the vendor clearly is trying its best to move from open
-to closed systems. I still remember when Garmin dropped NMEA support
-in its GPSes.</p>
-
-<p>A final idea was to build ones own unit, perhaps by basing it on a
-wearable hardware platforms like
-<a href="https://learn.adafruit.com/flora-geo-watch">the Flora Geo
-Watch</a>. Sound like fun, but I had more money than time to spend on
-the topic, so I suspect it will have to wait for another time.</p>

-<p>While I was working on tracking down links, I came across an
-inspiring TED talk by Dave Debronkart about
-<a href="https://archive.org/details/DavedeBronkart_2010X">being a
-e-patient</a>, and discovered the web site
-<a href="https://participatorymedicine.org/epatients/">Participatory
-Medicine</a>. If you too want to track your own health and fitness
-without having information about your private life floating around on
-computers owned by others, I recommend checking it out.</p>

- <div class="body"><p>Dear lazyweb,</p>
-
-<p>I wonder, is there a fitness tracker / health monitor available for
-sale today that respect the users privacy? With this I mean a
-watch/bracelet capable of measuring pulse rate and other
-fitness/health related values (and by all means, also the correct time
-and location if possible), which is <strong>only</strong> provided for
-me to extract/read from the unit with computer without a radio beacon
-and Internet connection. In other words, it do not depend on a cell
-phone app, and do make the measurements available via other peoples
-computer (aka "the cloud"). The collected data should be available
-using only free software. I'm not interested in depending on some
-non-free software that will leave me high and dry some time in the
-future. I've been unable to find any such unit. I would like to buy
-it. The ones I have seen for sale here in Norway are proud to report
-that they share my health data with strangers (aka "cloud enabled").
-Is there an alternative? I'm not interested in giving money to people
-requiring me to accept "privacy terms" to allow myself to measure my
-own health.</p>
