• Cloaked Archive Wiki

  16 mai 2011, par Multimedia Mike — General

  Google’s Chrome browser has made me phenomenally lazy. I don’t even attempt to type proper, complete URLs into the address bar anymore. I just type something vaguely related to the address and let the search engine take over. I saw something weird when I used this method to visit Archive Team’s site :

  
  
  

  There’s greater detail when you elect to view more results from the site :

  
  
  

  As the administrator of a MediaWiki installation like the one that archiveteam.org runs on, I was a little worried that they might have a spam problem. However, clicking through to any of those out-of-place pages does not indicate anything related to pharmaceuticals. Viewing source also reveals nothing amiss.

  I quickly deduced that this is a textbook example of website cloaking. This is when a website reports different content to a search engine than it reports to normal web browsers (humans, presumably). General pseudocode :

  PLAIN TEXT

  C :

  1. if (web_request.user_agent_string == CRAWLER_USER_AGENT)
  2.  return cloaked_data ;
  3. else
  4.  return real_data ;

  You can verify this for yourself using the wget command line utility :

  <br />
$ wget --quiet --user-agent="<strong>Mozilla/5.0</strong>" \<br />
 http://www.archiveteam.org/index.php?title=Geocities -O - | grep \&lt;title\&gt;<br />
&lt;title&gt;GeoCities - Archiveteam&lt;/title&gt;

  $ wget —quiet —user-agent="Googlebot/2.1"
  http://www.archiveteam.org/index.php?title=Geocities -O - | grep \<title\>
  <title>Cheap xanax | Online Drug Store, Big Discounts</title>
  

  I guess the little web prank worked because the phaux-pharma stuff got indexed. It makes we wonder if there’s a MediaWiki plugin that does this automatically.

  For extra fun, here’s a site called the CloakingDetector which purports to be able to detect whether a page employs cloaking. This is just one humble observer’s opinion, but I don’t think the site works too well :
  
  

  
  
  

• Create directory list where each line in list consists of mp3 file name and mp3 duration

  14 octobre 2015, par Kes

  I wish to produce a list from the directory of the mp3 file names in the directory and the playing duration of each file.

  The below command produces a list of mp3 files in the directory

  for name in *.mp3; do ffmpeg -i "$name" 2>&1 |  grep -o -P "(?<=Input #0, mp3, from ').*(?=.mp3':)"  ; done; 

  The below command produces a list of the duration of each of the MP3 files

  for name in *.mp3; do ffmpeg -i "$name" 2>&1 | grep -o -P '(?<=Duration: 00:).*(?=.[0-9]{2}, start)'  ; done;

  I need to combine the output of both these commands into one output showing

  • mm:ss filename
  • mm:ss filename
  • mm:ss filename
  • mm:ss filename
  • mm:ss filename
  • mm:ss filename
  • ..
