Tracker: Measures of Departmental Performance Missouri Department of Transportation

Reactive data sources such as Session or Minimongo internally create different Dependency objects for different pieces of data, each of which may be depended on by multiple computations. When the data changes, the computations are invalidated. Tracker.autorun allows you to run a function that depends on reactive data sources, in such a way that if there are changes to the data later, the function will be rerun.

Build and share your own collection of Tracker projects, videos and support docs. Search for projects and other resources by name, author, keywords or other metadata. Browser shows recently opened Tracker projects in a "recent local file" collection. Project Tracker is the gateway to information about more than 11,000 TxDOT projects, providing 24/7-access to the public, employees and elected officials.

Circle fitter tool fits circles to 3 or more points, steps or tracks. Export Video wizard enables editing and transcoding videos, with or without overlay graphics, using Tracker itself. Model overlays are automatically synchronized and scaled to the video for direct visual comparison with the real world. External models animate and overlay multi-point data from separate modeling programs such as spreadsheets and Easy Java Simulations.

Invalidating a computation that is currently invalidated or is stopped has no effect. A computation can invalidate itself, but if it continues to do so indefinitely, the result will be an infinite loop. Registers a new onInvalidate callback on the current computation , to be called immediately when the current computation is invalidated or stopped. It’s very rare to need to access currentComputation directly. The current computation is used implicitly byTracker.active ,dependency.depend() , and TRACKER.onInvalidate .

Tracker has been independently tested by Softpedia and found to be 100% clean. Except for TOPPER™ non-package jon boats, every TRACKER® Mod V, Deep V and GRIZZLY® model comes standard with a custom-fit trailer that is built to last as long as the boat it’ll carry. Do you have questions about which boat is best for you? We can easily help you over the phone as you shop, look for financing, or complete your purchase.

Calls func with Tracker.currentComputation temporarily set to nulland returns func‘s own return value. If func accesses reactive data sources, these data sources will never cause a rerun of the enclosing computation. A Dependency represents an atomic unit of reactive data that a computation might depend on.

As a project develops, its status may change from planning to design to construction. Browse projects in your area and find opportunities to get involved. The lost-and-found BLE technology locates your wallet even when it’s out of range of your paired device. If another person on the BLE network is near your tracker, their app will send you an anonymous update of your tracker’s location. Profile of the card is great and has alerted me a couple times so getting a good feel for how it can help me, if it can assist me I will get a lot of value out of this product. MoDOT has access to many resources, including people, funding, supplies and equipment.

TRACKER Boats are sold by a global network of quality independent boat dealers, as well as Bass Pro Shops and Cabela's Boat Centers. Each dealer is trusted to provide the best boat buying experience that exceeds customer expectations. Every MoDOT employee is responsible for delivering outstanding customer service. We want to build strong relationships with our transportation partners, our customers and each other. We work with our safety partners to promote safe behavior for all users and modes of transportation so everyone goes home safe every day.

The callback is run after any onInvalidate callbacks. Receives one argument, the computation that was invalidated. Stopping a computation invalidates it for the purpose of calling callbacks, but ensures that it will never be rerun. Fully-secure paper form scanning and manual key entry services for U.S. organizations and firms. Effortlessly convert hundreds or thousands of archived paper I-9s into compliant and easily manageable electronic forms.

Computations don’t have return values; they just perform actions, such as rerendering a template on the screen. Use stop to prevent further rerunning of a computation. An automatic flush occurs whenever the system is idle which performs exactly the same work as Tracker.flush. The flushing process consists of rerunning any invalidated computations. If additional invalidations happen while flushing, they are processed as part of the same flush until there is no more work to be done. Callbacks registered with Tracker.afterFlush are called after processing outstanding invalidations.
