• How many "Ruby on Rails" sites can be hosted using sub url in apache configuration file on apache4 with passenger4 on Ubuntu server ?

  17 octobre 2013, par user1731249

  Server's Hardware config :
  Ubuntu server 12.04, CPU : dual code (64-bit), RAM : 8GB, Disk : 200GB.

  Server's Software config :
  Apache2, Passenger4, Rails4, ruby2, MySQL.

  I'm developing a Ruby on Rails website which performs following tasks.

  1. Upload a series of images as zip.
  2. Extract zip images to temp directory.
  3. Convert series of images to video using FFMPEG.
  4. updating video info in MySQL db
  5. Viewing the video in HTML5 video tag.

  Maximum length of single video being 1min and on an average there may be 50 videos to be converted per day. I created three copies (Don't ask me why !) of same website and hosting three sites as sub-URLs like "example.com" being the domain and example.com/site1, example.com/site2, example.com/site3. Below is the Apache configuration :
  RailsAutoDetect off

  ServerName 127.0.0.1

      DocumentRoot /home/ubuntuuser/work/public
  
      ErrorDocument 404 /404.html
  
  
  
  RailsBaseURI /site1
  
  
  
      <directory></directory>home/ubuntuuser/work/site1/advisor/public>
  
              Allow from all
  
      Options -MultiViews
  
              RailsEnv production
  
      
  
  
  
  RailsBaseURI /site2
  
  
  
  <directory></directory>home/ubuntuuser/work/site2/advisor/public>
  
              Allow from all
  
      Options -MultiViews
  
              RailsEnv production
  
      
  
  
  
      RailsBaseURI /site3
  
  
  
  <directory></directory>home/ubuntuuser/work/site3/advisor/public>
  
              Allow from all
  
      Options -MultiViews
  
              RailsEnv production
  
      

  How many such sites can I host with sub-URLs without big performance drag ?
  Also please help to do a performance test for all the sub-URLs.

• Evolution #3336 : Amélioration sitemap.xml.html pour gestion des sites multilingues

  21 novembre 2014, par Guillaume Fahrner

  Ci joint le code complet du fichier sitemap.xml.html (j’ai perdu mon compte SVN et du coup je ne peux plus commit). J’ai du modifier la balise urlset comme le préconise google pour ajouter le namespace qui va bien. A part ca rien de bien fou, deux boucles traductions pour les rubriques et les articles en plus permettant d’ajouter les liens de traductions au sitemap.

  [(#REM)
      Exemple tres simple de sitemap.xml accessible via URL_SITE_SPIP/sitemap.xml
  
      (copier htaccess.txt en .htaccess pour en beneficier)
      Ce sitemap affiche la liste des rubriques, breves et articles, en se limitant a 1000 rubriques, 1000 breves et 2000 articles pour des raisons
  
      de performances.

• Google Speech API - Is there a way to determine if the audio has human voice or not ?

  20 décembre 2019, par stupid_sma

  I am making an audio filtering application at work that reads over hundreds of audio files and filters them. So, if the audio has human voice in it, it will accept it and if it does not- it will delete the audio file.

  I am using ffmpeg to get the details of the audio and add other filters like size and duration and silence (though it is not very accurate in detecting silence for all audio files.)

  My company asked me to try the Google Cloud Speech API to detect if the audio has any human voice in it.

  So with this code, some audio files return a Transcript of spoken words in the audio file, but what I need is to determine if a human is speaking or not.

  I have considered using hark.js for it but there does not seem to be enough documentation and I am short on time !

  Ps. I am an intern and I’m just starting out with programming. I apologize if my question does not make sense or sounds dumb.
