Can you make a sample code for a round robin algorithm with the following requirements for it to run in Java Apache Netbeans and no other IDE:1. The load balancer system.2. General worker node.  Do not hard code names, IP address(Please make sure you DO NOT HARD CODE), etc into this but instead have these passed in as parameters on the command line.  The node program will be running multiple times (either on the same machine or on separate ones)3. A program for sending jobs into the system.To potentially achieve a good mark in this assignment you will need to at least ensure your implementation considers:1. having different programs / projects as stated above;2. make use of multiple classes in each program;3. ensure that the relevant functionality for the class is contained within it;4. link classes together to form the overall algorithm;5. use multi-threading where necessary;6. send, receive and process messages7. only use the main method for extracting information from the arguments passed in from the command line and to start your system to ensure that you are not hard coding any system specific information;8. do not provide a monolithic solution (e.g. all code in one class or main method); and,9. do not introduce any form of OS scheduling techniques.  As this is a coordination system, you will only need to consider how to deal with working out which worker node needs to be sent a job message.In addition, you should also consider the following functional aspects:1. Each node will register with the load balancer by sending a message.2. The scheduler will record node details.3. Jobs require the load-balancer to assign the job to the next free node. The job information will detail the number of seconds that a job will take to run, rather than trying to include some form of code that is required to be executed.
4. The load balancer assigns the job to a node by sending it a message to work for X seconds. Nodes will receive job requests and wait for the required time. Once a job has finished on a node, a message will be sent back.

We are looking for a skilled developer to create a mobile/web application with image search functionality. The application will allow users to scan an image using their device's camera and search for that specific image in our database. Key Requirements: 1. Platform: The application should be developed for both iOS and Android platforms (for a native mobile app) or as a web application accessible from mobile browsers. 2. Image Search Functionality: Implement image search functionality where users can capture an image and find the scanned image in our database. The search process should be efficient and provide accurate results. 3. User Interface: Design an intuitive and user-friendly interface for capturing images, conducting searches, and viewing search results. The interface should be visually appealing and responsive across different devices. 4. Backend Development: Develop backend logic for handling image uploads, search requests, and database interactions. The backend should be scalable and efficient, even with a limited database. 5. API Integration: Integrate with device APIs (for mobile apps) for camera access and potentially with external APIs for additional functionalities. 6. Testing and Quality Assurance: Perform thorough testing to ensure the reliability, performance, and usability of the application. This includes unit testing, integration testing, and user acceptance testing. Additional Information: • The project timeline is flexible, but we're looking for timely delivery. • Please provide examples of past projects or relevant experience in mobile/web development and image processing. • I have problems when asked what our budget is! If you're able to complete the project then you will know what it will cost so please take no notice of the £20 and put forward your price please. If you have any questions or need further clarification, please feel free to reach out.
