  big on A7 and A53, while there’s a minor slowdown (almost within

• New proposed ePrivacy Regulation and why Piwik might not need tracking consent compared to Google Analytics & co

  11 janvier 2017, par InnoCraft — Community

  The EU is proposing new ePrivacy Regulations. The proposed Regulation on Privacy and Electronic Communications will increase the protection of people’s private life and open up new opportunities for business.

  

  The new ePrivacy Regulation proposal

  The proposal mentions several changes for example to the “Cookie Law” where no longer a cookie consent will be needed when the cookies improve the user’s internet experience, for example to remember the shopping cart history or when completing a form over several pages.

  However, consent to track a user’s behaviour may be needed in the future, unless the analytics data collection is hosted on the first-party website.

  From TheRegister : O’Neil noted a minor change in which visitors to a website for analytics purposes do not require consent, as long as any personal data collected is only processed by the first party.

  

  First party Analytics respecting privacy

  Piwik is an open-source analytics platform that is used on more than 1 million websites and apps in over 150 countries, and available in more than 50 languages. The difference with other analytics solutions is that you can download and install Piwik on your own infrastructure. Websites and mobile apps tracking users with their own Piwik very likely won’t require a consent from their users if these regulations become reality.

  We have regularly written about why privacy matters, or more recently 11 ways Piwik Analytics helps you to protect your visitors privacy.

  Besides the standard Piwik features, there are Premium Features that let businesses and organizations further maximize their success based on the tracked data. Need help in hosting Piwik on premise ? InnoCraft are THE Piwik experts and know it best as it is the company of the makers of Piwik. InnoCraft provides support subscriptions and enterprise packages to help you setting up, configuring and maintaining Piwik on your infrastructure as well as offer training and custom development.

  

  We’re excited to be building the best digital analytics platform which respects our privacy on the Internet.

  Thank you for being a valued member of the Piwik community !

• Updating ffmpeg on Ubuntu 12.04 ; conflicts with old version from standard repository

  29 octobre 2016, par Frank van Wensveen

  I have never used ffmpeg on my Ubuntu Linux 12.04 (Precise Pangolin) box until now. Typing ’ffmpeg’ at the command prompt revealed that ffmpeg 0.8.17 (listed as ffmpeg 0.8.17-4:0.8.17-0ubuntu0.12.04.2) was installed. Seeing as I need to convert h.265 to h.264, an update was obviously required.

  Following posted instructions, I installed a ream of packages :

  $ sudo apt-get install faad libmp4v2-dev libfaac0 libfaac-dev
  
  libxvidcore4 libxvidcore4-dev liba52-0.7.4 liba52-0.7.4-dev libx264-dev
  
  libgsm-tools libogg-dev libtheora-bin libfaad-dev libvorbis-dev 
  
  libtheora-dev libdts-dev git-core yasm texi2html checkinstall

  followed by

  $ sudo apt-get purge ffmpeg

  in order to get rid of the old stuff from the original repo.

  Downloaded the latest ffmpeg, and a ."/configure ; make ; sudo make install" later, I should be in business.

  Except that typing ’ffmpeg’ at the prompt still fired up the old version. A quick look revealed that the old ffmpeg binary was still sitting in /usr/bin with the new one being installed in /usr/local/bin. But ffmpeg is no longer listed as an installed package, and sudo apt-get remove ffmpeg tells me that "Package ffmpeg is not installed, so not removed".

  Running /usr/local/bin/ffmpeg directly works, however then fails in an Unknown encoder ’libx264’ error. Which is puzzling because the package libx264-120 is installed and /usr/lib/i386-linux-gnu/libx264.so.120 (with the appropriate symlink to /usr/lib/i386-linux-gnu/libx264.so) does exist.

  Maybe I’ve been looking at this for too long, because I’m sure this is a simple issue but I just can’t see it.

  Can someone please hand me the stupid had and point out why I deserve to wear it ?

  Tnx !
