I have a good idea for android app. I'd like to make the app to track the position and voice of user's girl/boy friend , wife or husband by using google map. The app must be hidden on mobile by user's setting. In the case of cancelling the "hide", it must be report to matched user. I have no spec, but the app is very simple. The app will be useful tool to manage the "Lovelace". I can provide $2500 to the app. But if you are the ideal candidate to implement my idea, I can add $500~$1000 more. -First : UI/UX -Second: Prototype You can divide the milestone with me. I hope a real developer. And you can write with "Lovelace" on top of cover letter.

Hi, We have an Android app, and we require it to manage the wifi network. But this can't be done through that app. We can extend that app using python, and using python we can't access core Android functions. We need an Android service that : 1. Wraps around the functionality of Android Wifi manager 2. Exposes 4 methods: a. Get current status of all Wifi - connected, list of APs, strength, etc b. Force scan of wifi c. Connect to wifi with the supplied password d. Disconnect current Wifi These methods can be called using JSON-RPC, TCP sockets, or any other way to communicate between 2 apps on android, EXCEPT the standard android communication system of messaging. Its a simple task for someone who knows android. Need it done ASAP. Have more such service that I would like developed, the right guy will get those as well. Thanks, Ashish

Requirements: 1. Create a C based code to find the least cost path between any two routers from a given set of six routers 2. Use Dijkstra’s algorithm and Distance Vector (DV) algorithm to find the least cost path. Each algorithm will generate its own least cost routing paths 3. The C program should be able to read a file (router.txt) for the cost information. 4. The C program should be able to find the least cost link for at least six routers 5. The least cost link details should be written to a file and to the console. Procedure: 1. Create a C-based code that runs on the linux machine. 2. Open the router.txt file and read the cost between the routers. Your code should be able to support at least six routers 3. Use the Dijkstra’s algorithm to find the least cost path between the routers 4. Use the same router cost information and compute the least cost path between routers using the Distance Vector algorithm (using Bellman-Ford equation) 5. The format of the input file is s d c Where s is the source, d is the destination, and c is the cost between source and destination. 6. Write to a file (LS.txt) and print to the console the forwarding table for all the routers that were computed using Dijkstra’s algorithm. The output file will have the destination router and least cost link connecting it 7. Also write to a file (DV.txt) and print to the console the forwarding table for all the routers that were computed using Distance-Vector algorithm. The output file will have the destination router and least cost link connecting it 8. The input and output file formats are shown below for the network shown in the below figure. The output file format shows only the output for two routers u and v. An example input file router.txt has been attached for the figure shown below. Input file format: u v 2 u w 5 u x 1 v x 2 v w 3 x w 3 x y 1 w y 1 w z 5 y z 2 Output File Format: v (u, v) w (u, x) x (u, x) y (u, x) z (u, x) -------- u (v, u) w (v, w) x (v, x) y (v, x) z (v, x) -------- : :

I am looking to have a well done, fully commented script put together as an example for the latest asyncio sockets technology, as well as a basic example for MongoDB. Using a list of 20,000+ URLs I can provide, I would like the script to be able to spawn off as many concurrent requests as I desire and fetch the result from each URL and store it into a MongoDB table. Essentially, a basic Http/Https client needs to be created in order to fetch and handle the requests, as I would like to send raw headers and receive the raw response from the server. The client should be able to handle any errors or timeouts (DNS that cannot resolve, or requests that simply time out) and be able to repeat the process again up to 3 times before determining the URL as bad and updating the database as such. I would also like the client to have the option of using a proxy for the requests (which I can also provide if needed). The purpose of this is to be as fast and lightweight as possible, so the lowest level objects possible should be used (Python standard library only). I will be using the script as a reference tool to building something a little different, so I could also pay you for your time, if interested, to answer any questions I may have on modifying the logic.

Budget and deadline: $75, < 48 hours Required experience: Multithreading asynchronous network and socket programming in 4.6 framework Specifications: .net 4.6 framework recently released SSL capabilities for C#, which I need to learn for my job. Please write me a multithreaded class which takes a line-by-line .txt of keywords, searches for them and scrapes the URLs from the results pages. If the .txt contains 5 lines launch 5 threads/sockets to search for them in Google simultaneously and asynchronously. Must be raw sockets. I don't want anything with TCPClient. From the research i've done it looks like .net released a cryptography update for x509. I've also seen posts about SSLStream. Must be able to read/write SSL headers without any extra references. Nothing 3rd party. Also must be able to use https proxies. Ipv4 and Ipv6. I can provide a list of ipv4/ipv6 proxies to test with.
