    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Privacy in Business : What Is It and Why Is It Important ?

    13 juillet 2022, par Erin — Privacy

    Privacy concerns loom large among consumers. Yet, businesses remain reluctant to change the old ways of doing things until they become an operational nuisance. 

    More and more businesses are slowly starting to feel the pressure to incorporate privacy best practices. But what exactly does privacy mean in business ? And why is it important for businesses to protect users’ privacy ? 

    In this blog, we’ll answer all of these questions and more. 

    What is Privacy in Business ?

    In the corporate world, privacy stands for the business decision to use collected consumer data in a safe, secure and compliant way. 

    Companies with a privacy-centred culture : 

    • Get explicit user consent to tracking, opt-ins and data sharing 
    • Collect strictly necessary data in compliance with regulations 
    • Ask for permissions to collect, process and store sensitive data 
    • Provide transparent explanations about data operationalisation and usage 
    • Have mechanisms for data collection opt-outs and data removal requests 
    • Implement security controls for storing collected data and limit access permissions to it 

    In other words : They treat consumers’ data with utmost integrity and security – and provide reassurances of ethical data usage. 

    What Are the Ethical Business Issues Related to Privacy ?

    Consumer data analytics has been around for decades. But digital technologies – ubiquitous connectivity, social media networks, data science and machine learning – increased the magnitude and sophistication of customer profiling.

    Big Tech companies like Google and Facebook, among others, capture millions of data points about users. These include general demographics data like “age” or “gender”, as well as more granular insights such as “income”, “past browsing history” or “recently visited geo-locations”. 

    When combined, such personally identifiable information (PII) can be used to approximate the user’s exact address, frequently purchased goods, political beliefs or past medical conditions. Then such information is shared with third parties such as advertisers. 

    That’s when ethical issues arise. 

    The Cambridge Analytica data scandal is a prime example of consumer data that was unethically exploited. 

    Over the years, Google also faced a series of regulatory issues surrounding consumer privacy breaches :

    • In 2021, a Google Chrome browser update put some 2.6 billion users at risk of “surveillance, manipulation and abuse” by providing third parties with data on device usage. 
    • The same year, Google was taken to court for failing to provide full disclosures on tracking performed in Google Chrome incognito mode. A $5 billion lawsuit is still pending.
    • As of 2022, Google Analytics 4 is considered GDPR non-compliant and was branded “illegal” by several European countries.

    The bigger issue ? Big Tech companies make the businesses that use their technologies (unknowingly) complicit in consumer data violations.

    In 2022, the Belgian data regulator found the official IAB Europe framework for user consent gathering in breach of GDPR. The framework was used by all major AdTech platforms to issue pop-ups for user consent to tracking. Now ad platforms must delete all data gathered through these. Biggest advertisers such as Procter & Gamble, Unilever, IBM and Mastercard among others, also received a notice about data removal and a regulatory warning on further repercussions if they fail to comply. 

    Big Tech firms have given brands unprecedented access to granular consumer data. Unrestricted access, however, also opened the door to data abuse and unethical use. 

    Examples of Unethical Data Usage by Businesses 

    • Data hoarding means excessively harvesting all available consumer data because a possibility to do so exists, often using murky consent mechanisms. Yet, 85% of collected Big Data is either dark or redundant, obsolete or trivial (ROT).
    • Invasive personalisation based on sensitive user information (or second-guesses), like a recent US marketing campaign, congratulating women on pregnancy (even if they weren’t expecting). Overall, 75% of consumers find most forms of personalisation somewhat creepy. 22% also said they’d leave for another brand due to creepy experiences.
    • Hyper-targeted advertising campaigns based on data consumers would prefer not to share. A recent investigation found that advertising platforms often assign sensitive labels to users (as part of their ad profiles), indicative of their religion, mental issues, history with abuse and so on. This allows advertisers to target such consumers with dubious ads. 

    Ultimately, excessive data collection, paired with poor data protection in business settings, results in major data breaches and costly damage control. Given that cyber attacks are on the rise, every business is vulnerable. 

    Why Should a Business Be Concerned About Protecting the Privacy of Its Customers ?

    Businesses must prioritise customer privacy because that’s what is expected of them. Globally, 89% of consumers say they care about their privacy. 

    As frequent stories about unethical data usage, excessive tracking and data breaches surface online, even more grow more concerned about protecting their data. Many publicly urge companies to take action. Others curtail their relationships with brands privately. 

    On average, 45% of consumers feel uncomfortable about sharing personal data. According to KPMG, 78% of American consumers have fears about the amount of data being collected. 40% of them also don’t trust companies to use their data ethically. Among Europeans, 41% are unwilling to share any personal data with businesses. 

    Because the demand for online privacy is rising, progressive companies now treat privacy as a competitive advantage. 

    For example, the encrypted messaging app Signal gained over 42 million active users in a year because it offers better data security and privacy protection. 

    ProtonMail, a privacy-centred email client, also amassed a 50 million user base in several years thanks to a “fundamentally stronger definition of privacy”.

    The growth of privacy-mindful businesses speaks volumes. And even more good things happen to privacy-mindful businesses : 

    • Higher consumer trust and loyalty 
    • Improved attractiveness to investors
    • Less complex compliance
    • Minimum cybersecurity exposure 
    • Better agility and innovation

  • Convert a video to audio on an android device (Java)

    25 mai 2012, par user1237578

    My problem is very basic, yet I find it incredibly hard to find a solution.

    I have made an android app which downloads videos from a server and is then supposed to convert them into mp3, because it's for music downloads. The problem now is that I can't really find a lightweight way of converting the videos.

    I have looked into a suitable ffmpeg library/wrapper already, but couldn't find a simple solution to use on the android. I'm already using ffmpeg on my windows machine, but it is console-based.

    All I need to do is convert mp4 into mp3 but somehow there doesn't seem to by any simple solution to find, also I'd rather not use an external web service because I can't rely on a website to always function, while my app should.

    I hope I've made myself clear, and thanks for taking the time to read this.

  • SOLVED - Compiling FFMPEG on Windows with Cywin and NDK r5

    19 mai 2012, par protectedmember

    This isn't a question - it's an answer for alll of you who have been facing the same problems as I have. I've been trying to compile this thing for a while now and I know of the numerous posts floating around the internet offering help. I have read and tried most of the suggestions and wanted to colate my success into this single post for others to benefit from.

    Since I don't have a blog, I thought it wouldn't hurt to post on here instead.

    I have managed to compile FFMPEG 0.10.3 (Freedom) on Windows 7 (32 bit) using NDK r5 and Cygwin. The steps :

    1 - Download/install Cygwin in the root of your C drive. I'm not going to give instructions on this, it's simple enough and there are plenty of tutorials on this.

    2 - Download NDK r5 from here and extract to the root of your C drive.

    3 - Download FFMPEG 0.10.3 from here and extract to the root of your C drive.

    4 - Open the file 'configure' in the root of the FFMPEG directory in a text editor.

    5 - Comment out lines 2073, 2074 and 2075.

    6 - Below 2075, add the following line :

    TMPDIR=c :/cygwin/tmp

    7 - Download this script (thankyou roman10) and place it inside your FFMPEG root directory. Rename the file to

    build_android.sh

    8 - Open the script in a text editor and edit line 17 to read

    c :/android-ndk-r5

    9 - Click start > run and type "bash" (without the speech marks) and press enter.

    10 - Type the following and press enter :

    cd /cygdrive/c/ffmpeg-0.10.3

    11 - Type the following and press enter :

    ./build_android.sh

    12 - Sit back and wait... libffmpeg.so will soon appear in your "c :\ffmpeg-0.10.3\android\" directory (where is defined in the bottom of the script from roman10's blog). The default architecture is armv7-a.

    The script from roman10's blog will actually compile quite a large shared object (.so) file. The compiler flags can be adjusted to suit your needs in the script from roman10's blog.

    I hope this helps,

    P.
