NetMQ PGM Multicast experience required Scope The Developer’s submission will demonstrate knowledge of Networks (Wired and Wireless), Sockets, PGM Multicast and specifically MSMQ and NetMQ (ZeroMQ). Submissions that are copy and paste that generally outline experience will be ignored. Submissions must address the whole scope of works. The awarded developer will be provided with 2 applications (Presenter and Participant) and will be required to sign a “Non-Disclosure Agreement”. Source code will be provided. Coding from scratch is not required. The developer will investigate and fix the following in both applications: Running the Presenter app on a wired Computer with Participant apps running on 2 wireless Computers. When Sending Screen from the Presenter app to the two wireless computers running the Participant app, it seems that the connection is blocked by the Wireless Access Point and both Wireless Participant apps stop receiving? I did once see an address was dropped from the ARP Table? This can also often result in an UnhandledException from the NetMQ library which must also be handled. (Note: Running the Presenter app and a Participant app both on Wireless seems to be ok) As mentioned above some issues result in an UnhandledException from the NetMQ library and results in the app being terminated. All exceptions must be handled and re-establish connections without terminating the apps. Expected Results: Both applications running on wired and wireless with both sending and receiving without stopping (being blocked) and without exceptions. 12 Wireless, C# Programming, Software Architecture, Socket IO, Network Administration Jul 25, 2017 Today1h 28m $995

OpenGL shader based program Hi, I want to have an OpenGL program (can be done by C++ or Java ) that reproduces the attached image by sending nine random points and 8 lines to the shader. (We don't want to render the small white spheres) Please see the attached image before you continue reading! The requirements as following: 1) By clicking a render button, we send generate nine random points and 8 lines(the lines use the same vertices, i.e each tow points are connected to each other to construct a line) 2) The vertices are sent to the vertex shader. 3)In the shader, from the nine points, we reproduce the spheres and the connection between them ( we might use more than one shader program one for the spheres and one for the stick) 4)The camera position must be changeable ( i.e the user can choose the position) 5)We must apply rotation, transformation, and zoom functionality. 6)The lighting position must be changeable ( i.e the user can choose the position) 7)VERY IMPORTANT: The code must be written in pure C++, Java or C#. Use only OpenGL API + Shader language. I.e no third party or library is allowed to produce the image or perform the camera rule. The KEY POINT is that ALL the work MUST be done in the shader. Clearly saying we send only the vertices and everything is done in the shader. Usually, raycasting is used for this purposes. I expect to get the work done in one week or so.
