• Why opencv3 requires libavcodec56 although opencv2 requires libavcodec57

  10 juin 2018, par TSR

  I have installed opencv using apt-get. I got opencv2 with the following version and it works fine :

  rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ python2.7
  
  Python 2.7.13 (default, Nov 24 2017, 17:33:09) 
  
  [GCC 6.3.0 20170516] on linux2
  
  Type "help", "copyright", "credits" or "license" for more information.
  
  >>> import cv2
  
  >>> cv2.__version__
  
  '2.4.9.1'

  Then I wanted to install opencv on a conda environment using pip. I got the following version

  (olfatf)rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ pip list | grep opencv
  
  opencv-python          3.4.0.14  

  However, I get the following error when I import the module :

  (olfatf)rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ python
  
  Python 3.4.3 |Continuum Analytics, Inc.| (default, Aug 21 2015, 00:53:08) 
  
  [GCC 4.6.3] on linux
  
  Type "help", "copyright", "credits" or "license" for more information.
  
  >>> import cv2
  
  Traceback (most recent call last):
  
    File "<stdin>", line 1, in <module>
  
    File "/home/pi/.conda/envs/olfatf/lib/python3.4/site-packages/cv2/__init__.py", line 3, in <module>
  
      from .cv2 import *
  
  ImportError: libavformat.so.56: cannot open shared object file: No such file or directory
  
  </module></module></stdin>

  I checked the install libavcodec library and I get the version 57.

  (olfatf)rover@rover_pi:/usr/lib/arm-linux-gnueabihf $ ls | grep libavformat
  
  libavformat.a
  
  libavformat.so
  
  libavformat.so.57
  
  libavformat.so.57.56.101

  So I want to know why a later version of opencv requires an older version of libavcodec. Also, how can I installed both libavcodec56 and libavcodec57 on my machine ?

  I use a raspberry pi with Raspbian Strech

• How to get your Matomo plugin ready for GDPR

  24 avril 2018, par Matomo Core Team

  Are you developing a plugin for your self-hosted Matomo ? Have you maybe published a plugin on the Matomo Marketplace ? Then we highly recommend you read this article.

  On 25th May 2018, new privacy regulations become effective called GDPR (General Data Protection Regulation) which applies to businesses worldwide. It is also known under different wordings in other countries, for example to RGPD in French and Datenschutz-Grundverordnung, DS-GVO in German.

  If your plugin is storing any personal information or tracks or imports any data, we highly recommend you give the GDPR guide a read. You may also want to read our blog as we are releasing new content about GDPR regularly.

  In Matomo 3.5.0, we will introduce new features for GDPR and we implemented it in a way that most – but not all – plugins will support these features out of the box without having to do anything.

  Nevertheless, we recommend every plugin developer to check out our developer guide on how to make your plugin GDPR compliant to see what you need to do. A beta version of Matomo 3.5.0 is already available so you can test these new features. You can find them by logging in to your Matomo and going to “Administration => Privacy”.

  Please note that any version of Piwik will not be GDPR compliant, so it is recommended that your plugin supports the latest version of Matomo (3.5.0+).

  The post How to get your Matomo plugin ready for GDPR appeared first on Analytics Platform - Matomo.

• Matomo 2 reaches end of life soon (December 2017), update now !

  7 décembre 2017, par Matomo Core Team — Community

  In less than three weeks, Matomo (Piwik) 2 will be no longer supported. This means that no further (security) updates will be released for this version. As per our Long Term Support announcement, Matomo 2.X is supported for 12 months after the initial release of Matomo 3.0.0 which was on December 18th 2016. Therefore, Matomo 2 will no longer receive any updates after December 18th 2017.

  It has been almost a year since we released Matomo (Piwik) 3 and we highly recommend updating to Matomo 3 ASAP. The major new release came with a new UI, performance and security improvements. If you are still on Matomo 2, the security improvements alone should be worth updating your Matomo to Matomo 3 now. We cannot recommend this enough.

  The update to Matomo (Piwik) 3 should be smooth, but may take a while depending on the amount of data you have.

  • If you have any problem with the update, feel free to get in touch with us, or ask in the forums.
  • If you are currently using Matomo (Piwik) self-hosted and would like to be upgraded, plus your Matomo managed in the official Cloud-hosted service, contact InnoCraft Cloud and they will migrate your database.

  At Matomo (Piwik) and InnoCraft, the company of the makers of Matomo, we have seen many thousands of Matomo installations upgraded over the past year and look forward to an exciting future for Matomo 3 and beyond !
