    Create script to parse input CSV file of fully qualified domain names using information from configuration file. Reject values that are obviously not a domain name (no “.”, spaces other than leading/trailing for example). The input file will have from 25,000 to 150,000 entries. Submit each value as an HTTP query to https://sgraph.umbrella.com/label/dt/name/criticalstart.com.json. The parsed value in this example is criticalstart.com. Example of submitting parsed value for response is curl --cert certificatekeys.pem:certpassword --cert-type pem https://sgraph.umbrella.com/label/dt/name/amu.adduraddonhere.info.json. The program should keep track of domains that have been submitted so the same domain is not submitted twice. For example, email.abc.com and web.abc.com would be the same domain. The query will submit an HTTPS request over SSL that requires client side authentication. Data via JSON will be returned. Need to parse out value pairs for “label”, “confidence”, and “score”. The original value of the URL should be retained – in some cases the lookup value and original may be the same. Write results to text file. The initial program should be a script that can be easily run on Windows or Linux. Something that can be easily compiled would be good as well.Program should be started with a configuration file each time.

    I need an android developer who can customize an android rating bar(http://developer.android.com/reference/android/widget/RatingBar.html) designed as per the mock-up (See attachment). There is 1 rule.1. The drawable used CANNOT be a regular image. It must either be an extension of the shape drawable class or a shape defined via xml. YOU WILL NOT BE REWARDED IF YOU USE A REGULAR IMAGE (I could have done this myself). You can also extend the RatingBar class if necessary to achieve the effect.Due to the nature of the project I want to be able to customize the rating bar on the fly so I cannot have hundreds of drawables packed with the project. If you can video of the view in action it would be greatly appreciated and will probably win you the project. Type &quot;I understand and I can complete this project.&quot; in your bid so I know your not a bot. Happy bidding.

    Im also in SL. Can you give me ur email ID or phone number for direct contact? Price can be discussedIt is a small assignment. need urgent! Everything will be checked with plagiarism detection tool. So please put a reference. (no problem if it is coppied, but must acknowledge)Practical Part 1 - C++ Data Structures and Algorithms //You are working as a high-paid optimizer in a respectable game company. Your team leader has stopped by at your office 8:00 AM and given you a task: given code needs to be optimized by tomorrow. Yikes! You see a letter and source code on your desk. &quot;Good day, I now you are capable for performing this sort of feat, so can make a safe bet you don&quot;t fail me. This code is an essential part of you-know-what-game that will break sales records from here to Hong Kong. However, current implementation is dead slow for some reason - I need you to explain to me what it does and why it is so slow. I&quot;ve always felt that a picture tells more than thousand words, so illustrate its operation to me using one. I am not a computer-literate guy, so make it easy to understand. And while you&rsquo;re at it, be a good chap and optimize it. And write those time complexitity-whatcha-call-them, too - guys as the lab want them for some reason.Regards,Your Chief Executive Officer.&quot;//In other words:1.Explain code operation in words (English).2.List drawbacks of used algorithm/data structures.3.Draw a picture of the algorithm operation (before optimization) so that your computer-illiterate team leader can figure out what makes it so slow.4.Replace used data structures with more efficient (and readable) solutions and give reasoning for your choice. Ie. how this is beneficial, why not some other data structure.5.Optimize CRenderQueue class member functions code via more efficient algorithm (no assembly language required).6.Analyze and provide reasoning for time complexityoBefore optimizationoAfter optimizationSubmit modified source code + pictures as your answer in a zip file. Note: Everything will be checked with plagiarism detection tool. Acknowledge with reference if you taken from the internet or other resources. Otherwise you will be graded as 0 and failed.
