• Data Privacy Day 2021 : Five ways to embrace privacy into your business

  27 janvier 2021, par Matomo Core Team — Community, Privacy

  Welcome to Data Privacy Day 2021 !

  This year we are excited to announce that we are participating as a #PrivacyAware Champion for DPD21 through the National Cyber Security Alliance. This means that on this significant day we are in partnership with hundreds of other organisations and businesses to share a unified message that empowers individuals to “Own Your Privacy” and for organisations to “Respect Privacy.”

  "Last year dawned a new era in the way many businesses operate from a traditional office work setting to a remote working from home environment for employees. This now means it’s more important than ever for your employees to understand how to take ownership of their privacy when working online."

  As a Data Privacy Day #PrivacyAware Champion we would like to provide some practical tips and share examples of how the Matomo team helps employees be privacy aware.

  

  Five ways to embrace privacy into your business

  1. Create a privacy aware culture within your business

  • Get leadership involved.
  • Appoint privacy ambassadors within your team. 
  • Create a privacy awareness campaign where you educate employees on your company privacy policy. 
  • Share messages about privacy around the office/or in meetings online, on internal message boards, in company newsletters, or emails. 
  • Teach new employees their role in your privacy culture and reinforce throughout their career.

  2. Organise privacy awareness training for your employees

  • Invite outside speakers to talk to employees about why privacy matters. 
  • Engage staff by asking them to consider how privacy and data security applies to the work they do on a daily basis.
  • Encourage employees to complete online courses to gain a better understanding of how to avoid privacy risks.

  3. Help employees manage their individual privacy

  • Better security and privacy behaviours at home will translate to better security and privacy practices at work. 
  • Teach employees how to update their privacy and security settings on personal accounts.
  • Use NCSA’s privacy settings page to help them get started

  4. Add privacy to the employee’s toolbox

  • Give your employees actual tools they can use to improve their privacy, such as company-branded camera covers or privacy screens for their devices, or virtual private networks (VPNs) to secure their connections.

  5. Join Matomo and we’ll be your web analytics experts

  • At Matomo, ensuring our users and customers that their privacy is protected is not only a core component of the work we do, it’s why we do what we do ! Find out how.

• ffmpeg works at command line but I got this error when I use it in nodejs app :

  15 avril 2023, par Ibrahim Ashour

  This is the code :

  


  import fs from 'fs';
import googleTTS from 'google-tts-api';
import https from 'https';
import { exec } from 'child_process';

async function convertTextToVoice(text, fileName) {
  const outputFile = `./audios/${fileName}.mp3`;

  const words = text.split(' ');
  const chunks = [];
  let chunk = '';

  for (const word of words) {
    if (chunk.length + word.length < 200) {
      chunk += ' ' + word;
    } else {
      chunks.push(chunk.trim());
      chunk = word;
    }
  }

  chunks.push(chunk.trim());

  for (let i = 0; i < chunks.length; i++) {
    const chunkFile = `./audios/${fileName}-chunk${i}.mp3`;
    const url = await googleTTS.getAudioUrl(chunks[i], {
      lang: 'ar',
      slow: false,
      host: 'https://translate.google.com',
    });


    try {
      const file = await fs.createWriteStream(chunkFile);
      https.get(url, response => {
        response.pipe(file);
        file.on('finish', () => {
          file.close();
          console.log(`Chunk ${i} created successfully`);
        });
      }).on('error', error => {
        console.error(`Error downloading chunk ${i}: ${error}`);
      });
    } catch (error) {
      console.error(error);
    }
  }

  const chunkFiles = chunks.map((chunk, i) => `./audios/${fileName}-chunk${i}.mp3`);

  // Use ffmpeg to merge the audio files
  const concatCommand = `ffmpeg -i "concat:${chunkFiles.join('|')}" -acodec copy ${outputFile}`;
  try {
    await new Promise((resolve, reject) => {
      exec(concatCommand, (error, stdout, stderr) => {
        if (error) {
          console.error(`Error executing ffmpeg command: ${error}`);
          reject(error);
        } else {
          console.log(`Audio file ${outputFile} created successfully`);
          resolve();
        }
      });
    });

    for (const chunkFile of chunkFiles) {
      await fs.promises.unlink(chunkFile);
      console.log(`${chunkFile} deleted successfully`);
    }

  I expected the command to work in the nodejs app like in the command line

  


• PHP-FFMPEG Waveform is a little noisy, how to fix that ?

  18 avril 2023, par Kranchi

  I made a waveform through sample code :

  


  $waveform = $audio->waveform(2000, 500, array('#FFA500'));
$waveform->save('waveform.png');


  


  But result has some noise in top & bottom of edges :
https://gcdnb.pbrd.co/images/80v6Up6etCrD.png?o=1

  


  So I made a tiny change in line 140 of src\FFMpeg\Media\Waveform.php :

  


  //'showwavespic=colors='.$this->compileColors().':s='.$this->width.'x'.$this->height,
'showwavespic=draw=full:colors='.$this->compileColors().':s='.$this->width.'x'.$this->height,


  


  And problem fixed :
https://gcdnb.pbrd.co/images/KsCFsOujmJ9W.png?o=1

  


  I'm not sure is this a bug or problem in FFMpeg dll file and my question :

  


  is it possible to send the new command or override save method to avoid hacking the original file ? (the save method is using some protected methods)

  


  https://github.com/PHP-FFMpeg/PHP-FFMpeg/blob/master/src/FFMpeg/Media/Waveform.php

  


  Thanks.
