Help us Reset The Net today on June 5th
This blog post explains why the Piwik project is joining ResetTheNet online protest and how you can help make a difference against mass surveillance. It also includes an infographic and links to useful resources which may be of interest to you.
Snowden revelations, a year ago today
On June 5, 2013 the Guardian newspaper published the first of Edward Snowden’s astounding revelations. It was the first of a continuous stream of stories that pointed out what we’ve suspected for a long time : that the world’s digital communications are being continuously spied upon by nation states with precious little oversight.
Unfortunately, mass surveillance is affecting the internet heavily. The Internet is a powerful force that can promote democracy, innovation, and creativity, but it’s being subverted as a tool for government spying. That is why Piwik has decided to join Reset The Net.
June 5, 2014 marks a new year : a year that will not just be about listening to the inside story of mass surveillance, but a new year of fighting back !
How do I protect myself and others ?
Reset the Net is asking everyone to help by installing free software tools that are designed to protect your privacy on a computer or a mobile device.
Reset the Net is also calling on websites and developers to add surveillance resistant features such as HTTPS and forward secrecy.
Participate in ResetTheNet online protest
Have you got your own website, blog or tumblr ? Maybe you can show the Internet Defense League’s “Cat Signal !” on your website.Get the code now to run the Reset the Net splash screen or banner to help make privacy viral on June 5th.
Message from Edward Snowden
Evan from FFTF sent us this message from Edward Snowden and we thought we would share it with you :
One year ago, we learned that the internet is under surveillance, and our activities are being monitored to create permanent records of our private lives — no matter how innocent or ordinary those lives might be.
Today, we can begin the work of effectively shutting down the collection of our online communications, even if the US Congress fails to do the same. That’s why I’m asking you to join me on June 5th for Reset the Net, when people and companies all over the world will come together to implement the technological solutions that can put an end to the mass surveillance programs of any government. This is the beginning of a moment where we the people begin to protect our universal human rights with the laws of nature rather than the laws of nations.
We have the technology, and adopting encryption is the first effective step that everyone can take to end mass surveillance. That’s why I am excited for Reset the Net — it will mark the moment when we turn political expression into practical action, and protect ourselves on a large scale.
Join us on June 5th, and don’t ask for your privacy. Take it back.

FFMPEG - Converting any kind of file to Mp4 compatible with IOS and Flash
5 février 2013, par arashagaI am struggling with FFmpeg whithing Drupal Video Module to produce files to MP4 that is compatible with IOS and Flash Player10 and up.
I have used the following commands so far, please note that the variables starting with " !" are placeholders and will be replaces with the proper items :FFmpeg -strict experimental -y -i !videofile -pass 1 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -an !convertfile
FFmpeg -strict experimental -y -i !videofile -pass 2 -s !widthx!height -b:v 500k -threads 0 -vcodec libx264 -vf "pad=!paddingwidth:!paddingheight:!paddingleft:!paddingtop:000000" -preset slow -acodec aac -ab 128k !convertfileThe above command produce an error as :
error executing command for rendering preset HTML5 MP4, command #1 :

The encoder 'aac' is experimental but experimental codecs are not enabled, add '-strict -2' if you want to use it.
Alternatively use the non experimental encoder 'libfaac'.Another command that I used is :
FFmpeg -i !videofile -an -pass 1 -vcodec libx264 -preset slow -b 500k -threads auto !convertfile
FFMpeg -y -i !videofile -acodec libfaac -ab 128k -pass 2 -vcodec libx264 -preset slow -b 500k -threads auto !convertfileOutput for the first pass :
