Requirements Interview Answers:
To help you bid more accurately, the buyer was interviewed about the requirements for this bid request. Below are their answers. Untitled Page
Bid request Type: What kind of work do you need done?
Software related (Includes desktop applications and internet websites)
Bid request Parts: What do you want the worker to do on this bid request?
Requirements: The worker will analyze the problem and propose a software-based solution to the problem.
Programming: The worker will take the requirements and translate them into the language of the computer (and test it).
User installation: The installer will move the software from the place it was created (which is called the development or QC environment) to where you will use it (which is called the production environment). The installer then tests the software to make sure that the installation was done properly and completely.
Req. Doc. Type: What kind of documentation do you want for this bid request?
Informal documentation - As the buyer talks back and forth about the bid request with the worker, those conversations become the requirements.Remember to communicate ALL of the details of your bid request on the Rent A Coder site. If you don't, and there is a dispute, then important details of the contract will not be documented and cannot be taken into account in arbitration. If you feel you MUST go offsite (for example, using the phone or IM) then afterwards post everything onsite and get the other party to post that they agree to those contractual terms.
Program Type: What kind of software should the worker create (and/or install)?
  • A desktop or server program: This software runs on a user's own PC/workstation, or on a server.
Desktop / server program info
Size of application: How many screens/forms need to be created/edited in this application?
I don't know.
Other info:- One window for displaying the video stream on the receiver side
- One window for displaying a preview of the video stream on the sender side

  • C++ / C
  • Java
Operating system(s) What operating systems(s) do you want your application to work on?

    Database: Will this bid request include a database?
    No, it does not include a database.
    Installation Program: Does the worker need to create an installation program?
    No. The worker needs to only give me instructions on how to install it.
    Legal: 1) I require complete and fully-functional working program(s) in executable form as well as complete source code of all work done (so that I may modify it in the future).
    2) Deliverables must be in ready-to-run condition as follows (depending on the nature of the deliverables):
    2a) If there are any server-side deliverables (intended to only exist in one place in the Buyer's environment) then they must be installed by the Worker in ready-to-run condition (unless specified elsewhere by the Buyer).
    2b) All other software (including but not limited to any desktop software or software the buyer intends to distribute) must include a software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request (unless specified elsewhere by the Buyer).
    3) All deliverables will be considered "work made for hire" under U.S. Copyright law. Buyer will receive exclusive and complete copyrights to all work purchased.
    3b) No part of the deliverable may contain any copyright restricted 3rd party components (including GPL, GNU, Copyleft, etc.) unless all copyright ramifications are explained AND AGREED TO by the buyer on the site per the worker's Worker Legal Agreement.
