very expensive for 24/7 server but very inexpensive if used for on-demand storage/computation consequently, do not use it as your main hosting platform except if get direct revenues from it (stick to having your own actual server in a datacenter, no VPS, no cloud) if you want to rent to a client for a short period of time or you can charge him a higher cost and minimize your setup cost (through an AMI) it's nice too



  • the Connect button provides all the required ssh information (with the proper key)
  • Putty error on Windows "Unable to use key file "my_key.pem" (OpenSSH SSH-2 private key)"

Novelty discovery HIT

Facilitate novelty discovery.


gather links following few simple rules

  • has to be new (not already part of the list)
  • can not be "people"


http://www.ifi.uzh.ch/ddis/research/semweb/simpack/ 2005 2008

  • will earn X

http://www.e-lico.eu/ 2009 2012

  • will earn Y

without starting date or without finishing date each project will earn less


  • limit to research project? labs? published?
  • consider "grapes" of projects, for example ITER or LHC are spawing a myriad of sub-projects
  • checking the result without wasting time
    • quality of each link knowing that it will probably be hundreds of them

(( ask for other turkers to check it but Im afraid they would be too "positive" since I guess there is a kind of turkers community (since they are dedicated websites already)

  • only allowed for US resident to pay for tasks

Notes as a requester

Economical arm race (Seedea:Research/Drive) between

  • the person wanting the information (Requester)
  • the community (including but not limited to the official https://requester.mturk.com/mturk/welcome )
    • unorganised individuals
      • AI researchers
    • organised individuals
      • practionner websites
      • legal entities

Work is done (or not) as when the equilibrim is reach between perceived

  • price defined by estimation of
    • maximum number of items (HITs)
    • total budget
    • value of the processed result
      • thus based on the ulterior motive
    • amount of work required per task
    • amount of work required to handle the result of every task

The community is not homegeous regarding its skills and its economical needs, consequently one might prefer a distribution rather than a over simplified view.

From the requester point of view, the price could also be started as the lowest point then increased over time in order to cover the larger number of item at the lower price then increasing, presumably based on the difficulty to conduct the remaining HITs. This is probably specific to this problem though. Also note that if the community perceive that prices increase over time, it could give the incentive to delay participation.

My notes on Tools gather what I know or want to know. Consequently they are not and will never be complete references. For this, official manuals and online communities provide much better answers.
