I need a java script framework for displaying and computing a large amount (1000+) of countdowns on one page, simultaneously. The design of the countdown should be exactly like the one on this page: [login to view URL], but without the animation. Following rules apply to the countdown: • The countdown should display milliseconds with 3 digits always • Minutes, hours and seconds have to show always two digits (so with a leading zero if < 10) • The countdown should display days with at least 2 digits, up to unlimited • No animation The framework should be designed, so that the countdowns run smoothly and cause the lowest possible cpu utilization. The framework should use an array of UNIX timestamps as an input parameter to create the countdowns. It should create one countdown for each timestamp in the list and map it to the corresponding div. countdown0, countdown1, countdownN... Performance Hint: With each cycle all countdowns should be updated in one callback (reffering to the setInterval method in JS), instead of initiating a callback for each countdown, unless you come up with a better solution. The performance goal is: 1000 simultaneously running countdowns should run with at least 1 frame per second in the Google Chrome browser. My current prototype attached has about 10 frames per second.

Greetings, the task itself is easy, however I can't grant that you'll get a desired performance even with optimized code, since browser rendering affects it as well as actual computing, and it's out of control. I can make a quick solution with css, and if turns out to be not enough, we can try canvas rendering with haxe for example. ----------------------------------- Regards, Oleg

Hello Mr. We typically estimate a complex website (with lots of functionality) to be about 120-145 hours worth of labor and a basic website (with minimal functionality) to be about 40-50 hours of labor. Our timeline is typically about 2 to 4 weeks. If you have your materials prepared and ready-to-go, the timeline goes down to 1-2 weeks. Asking "How much is a website?" is kind of like asking, "how much is an automobile?" Factor in what you need, the tools available, your budget, and your timeline. CodeShin will build your website in an iterative approach. You may specify what you need based on priorities, with different functional elements coming online in a staged approach. Our payment structure is typically in three parts: a deposit payment, a mid-way payment, and launch payment. We also offer monthly plans and equity-only arrangements. DELIVERABLE 1: Website planning DELIVERABLE 2: Design concepts DELIVERABLE 3: Landing Stage 1, beta - uploaded site DELIVERABLE 4: Custom displays DELIVERABLE 5: Landing Stage 2 - Design overlay and custom functionality DELIVERABLE 6: Testing, Quality Control, and launch front-end DELIVERABLE 7: Training and documentation ADD-ONS We offer maintenance packages and social networking packages to assist you in extending your website's reach and building your community of clients online. Thank you!
