    I need an app built using the google maps api. Much like Waze, but the goal is not consumer gps usage, instead we need the ability to create virtual location positions ontop of the Google maps api. I can"t explain fully on here, but the project would be used on social websites where users have the ability to add a location to the map, and that location show up on other users application, with the ability to search locations created by usersI"m looking to get an estimate and find someone willing to work on the project over time. Message me if you would like more information.

    Implement a Genetic Algorithm in Java using NetBeans or Eclipse for test suite minimisation/reduction.The GA should be able to take in test case coverage details from a .txt file that has been manually inputted. There will be bout 100 test cases with branch coverage details that form the test suite.Then this information will be ran through the GA to try and reduce the total amount of test cases that cover the same coverage for the test suite. e.g. say from 100 test cases reduced to 60 test cases with the same coverage as before.The test cases in the new created test suite will then be ran against software manually to work out the reduction in execution time to work out a measure of effectiveness compare to the original test suite.

    I need software to log data from one or more air quality monitors. When the temperature, humidity or CO2 level is outside a user selected range, an email message (and/or text message) must be sent to the user. The user must be able to view the current conditions and the logs of previous readings in a graphical format from within the software user interface and have the option of downloading readings in CSV format. The user must also be able to set the range at which notification email/texts will be sent.The user will have one or more devices so he should be able to monitor each of them from the user interface page.The software needs to be easy to install.First I would like a version that can be run on a local computer. Later I would like a version that that the user can simply log into, that will run on a cloud server like AWS, etc.BUT FIRST I NEED THE LOCAL VERSION!A test NOSE unit can be accessed at (user id-= admin / password= noseadmin)A FLASH interface is available here - (flash screen) -I don"t think the id and password are needed to view the flash screenThe temp, RH & Co2 can be accessed here: (sensor data, text format -sen1 is temp, 2 is RH & 3 is CO2 level)The temp, RH & CO2 data can be accessed directly at the following addresses: (current temp, C) (current RH level) (current CO2 level, ppm)Here are some other views: (sensor data, text format) (flash screen) (displays all info about device) (links to different data) (last few CO2 readings –bottom is most recent) >> There are a lot of these “setget?%pid-…” things listed on the diag screen >> anything listed on the diag screen proceeded by “setget?” will display the value. I don’t know if this is of any use to us.Thank you! If you need more info let me know. Dan Weddle ~ DX Hydro Co. Iowa, USA
