  Hey everyone,

  Matthieu here, Founder of Matomo.

  Today is one of the most significant days of the year for the Matomo team – it’s Data Privacy Day. And so I wanted to quickly reflect on our mission and the significance of this day. 

  In today’s busy online world where data is king, this day is an important reminder of being vigilant in protecting our personal information online.

  Matomo began 12 years ago as an open-source alternative to Google Analytics – the goal was, and still is to give full control of data back to users. 

  In 2020, we are determined to see through this commitment. We will keep building a powerful and ethical web analytics platform that focuses on privacy protection, data ownership, and provides value to all Matomo users and customers.

  And what’s fantastic is to see the rise of other quality software companies offering privacy-friendly alternatives for web browsers, search engines, file sharing, email providers, all with a similar mission. And with these products now widely available, we encourage you to take back control of all your online activities and begin this new decade with a resolution to stay safe online.

  I’ll provide you with some links below the video to check out these privacy-friendly alternatives. If you have a website and want to gain valuable insights on the visitors while owning your data, join us ! 

  Matomo Analytics On-Premise is and always will be free to download and install on your own servers and on your own terms.

  Also feel free to join our active community or spread the word to your friends and network about the importance of data privacy.

  Thank you all and wishing you a great 2020 !

• Pygame : Frame ghosting ?

  31 décembre 2013, par Sam Tubb

  I am working on a animation environment in python using pygame. The user draw's each frame, and then using ffmpeg the animation is saved as an .avi movie. I would like to implement a feature, but am not sure how.. frame ghosting. Like display the previous frame while you draw the current.

  I tried creating a surface called ghost that copies the current frame when the next-frame key is pressed. Then draws it with an alpha level of 10, but this didn't work out correctly.

  I am not sure what to do, here is the source code for anyone that thinks they have an idea :

  #Anim8
