• 9 plugins you should definitely have heard of to prevent data leaks, security breaches and to get more flexibility in the way you log in to your Piwik.

  9 janvier 2017, par InnoCraft — Community

  At Piwik and at InnoCraft, we have always focussed on Security and take it very seriously. We were one of the first open source projects to offer a bug bounty for reporting security issues responsibly, Piwik has gone through several security audits and all changes in Piwik go through security reviews by our security experts.

  On the Piwik Marketplace you will find some plugins that give you just that extra bit of additional security to keep your data even more secure and to let you secure how your users log in to your Piwik.

  Security Info

  This plugin provides security information about the server(s) your Piwik is running on and offers suggestions on how to improve the security settings of your servers. We highly recommend to install the Security Info plugin. Checks performed include for example usage of the latest PHP version, usage of latest Piwik version, usage of PHP ini settings like magic_quotes_gpc and more. More details & download

  Google Authenticator

  This plugins adds Two Factor Authentication, also known as 2FA, to Piwik. When logging in to Piwik, it forces you to confirm the identity by utilizing a combination of two different components. This means if someone knows your password, they will still need the other component in order to successfully log in, in this case a code that changes every minute on your phone.

  Activity Log

  The plugin gives you a detailed audit log of all activities that happen in your Piwik for better security and problem diagnostic. It provides documentary evidence of over 80 different activities that happen in your Piwik and lets you for example see when someone successfully logged in, when someone tried to log in with your username, when someone deleted data, and much more.

  Performance Info

  This plugin checks your Piwik configuration and compares it with some best practice settings. For example whether debug modes are disabled in a production environment, whether the example plugins that are shipped with Piwik are disabled, and more.

  Login Ldap

  Login Shibboleth

  Shibboleth is an open-source project that provides a Single Sign-On and allows websites to make informed authorization decisions in a privacy-preserving manner.

  Login Http Auth

  This plugin allows you to sign in to your Piwik using the HTTP Auth protocol instead of the standard login mechanism. It extends the standard Piwik authentication to use Basic HTTP Authentication. This may be useful if you use Basic HTTP Authentication already anyway and don’t want to manage your users additionally in Piwik itself. We recommend to use this only over SSL, for example with the Force SSL plugin. More details & download

  Custom Development

  Piwik is an analytics platform that you can extend and customize to your needs. Besides many configuration options you can change existing functionality and also build new functionality on top of Piwik, for example to log in to your Piwik via any Single-Sign-On. Read more about extending Piwik on the Piwik Developer Zone or get in touch with us and we take care of it for you.

• Python extract wav from video file

  How to extract audio from a video file using python ?

  



  Extract audio from video as wav

  



  How to rip the audio from a video ?

  



  My question is how could I extract wav audio track from video file, say video.avi ? 
I read many articles and everywhere people suggest to use (from Python) ffmpeg as a subprocess (because there are no reliable python bindings to ffmpeg - the only hope was PyFFmpeg but i found it is unmaintaned now). I don't know if it is right solution and i am looking for good one.
  
I looked to gstreamer and found it nice but unable to satisfy my needs — the only way I found to accomplish this from command line looks like

  



   gst-launch-0.10 playbin2 uri=file://`pwd`/ex.mp4  audio-sink='identity single-segment=true ! audioconvert ! audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)16000, channels=(int)1 ! wavenc !  filesink location=foo.wav’ 


  



  But it is not efficient because i need to wait ages while playing video and simultaneously writing to wav file.

  



  ffmpeg is much better :

  



  avconv  -i foo.mp4  -ab 160k -ac 1 -ar 16000 -vn ffaudio.wav


  



  But i am unable to launch it from python (not as a command line subprocess). Could you please point me out pros and cons of launching ffmpeg from python as a command line utility ? (I mean using python multiprocessing module or something similar).

  



  And second question.

  



  What is simple way to cut long wav file into pieces so that i don't break any words ? i mean pieces of 10-20 sec length with start and end during the pause in sentences/words ?

  



  i know how to break them on arbitrary pieces :

  



  import wave


win= wave.open('ffaudio.wav', 'rb')
wout= wave.open('ffsegment.wav', 'wb')

t0, t1= 2418, 2421 # cut audio between 2413, 2422 seconds
s0, s1= int(t0*win.getframerate()), int(t1*win.getframerate())
win.readframes(s0) # discard
frames= win.readframes(s1-s0)

wout.setparams(win.getparams())
wout.writeframes(frames)

win.close()
wout.close()


  


• It’s January 28th : Let’s celebrate Data Privacy !

  29 janvier 2018, par Matomo Core Team

  It is a special Sunday here for us at Matomo, as today is international Data Privacy Day. The day was created in 2007 to raise awareness of the importance of data privacy for people and businesses worldwide.

  

  What is data privacy about ?

  Personal data refers to any data which is collected and can be linked to an individual human being such as phone records, credit card transactions, GPS position, IP addresses, browsing history… So basically, personal data refers to your identity online. That is why you should be highly concerned about sending your personal data (or your customers’ personal data) away. It is important to be aware of who is collecting the information and how it is being used.

  What big changes are happening in 2018 ?

  New privacy regulations GDPR comes into play next May 2018 : GDPR will bring about some changes (in the right direction) by making people and businesses aware of what data privacy means, and what they should be doing to protect their customers’ privacy. With these new regulations, data privacy awareness is reaching a critical milestone this year.

  How can I protect my privacy ?

  Here are a few tips to protect your privacy :

  • Educate yourself on the importance of privacy : the more informed you are the better.
  • Use open source solutions where you can keep full control of your own data (such as NextCloud instead of Dropbox and of course Matomo instead of Google Analytics),
  • Experiment with different online services to protect your data privacy, for example using an alternative search engine (such as DuckDuckGo instead of Google) or an alternative email provider (such as ProtonMail).

  What’s coming next for Matomo and Privacy ?

  Here at Matomo, we are building the leading decentralised open web analytics platform. We’re currently working on new sets of privacy features to make compliance with GDPR a breeze. Stay tuned here to be notified when we launch the new privacy compliance tools !
