coarse weave

Selecting SOA means that business processes or functions are expressed by services, and the granularity of services directly affects the quality of services, including flexibility and efficiency. Therefore, selecting appropriate granularity is crucial to service design. As I was asked, I had the idea of writing something about "service granularity" before the festival. I did not expect it to disturb my National Day. Looking back, one of the most important reasons is that the industry does not ha

Polygon Tiling with Coverage masks" The idea was used). The rasterization of the equation of the edge to the covered tile works very much like a rasterized pixel; what we want to do is to calculate the upper and lower bounds of the tile according to the equation of the edge, because the equation is linear, so the extremum is on the boundary of the tile-in fact, you can loop 4 corner points, The symbols of A and b factors in the formula can be used to determine which corner it is. The line at th

the stateless service. Control of service granularity The control of service granularity in SOA system is a very important design task. Typically, a coarse-grained interface is recommended for services that expose the entire system, whereas a relatively fine-grained service interface is typically used internally within an enterprise system architecture. Technically, a coarse-grained service interface might

suggestions for the future update of the module. You can quickly and easily use these functions-of course, if they were later included, the name or interface details would be different. One category that may be very common is a function that takes multiple iterable as arguments and then generates individual elements from each iterable. In contrast, izip () produces element tuples, while IMAP () produces values computed from the base element. The two arrangements that are clear in my mind are c

, design its standalone mode, in order to develop quickly, at first do not need to consider service (such as Master/slave) fault tolerance, then develop the corresponding wrapper, By deploying the services in Stanlone mode to the resource management system yarn or MESOS, the resource management system is responsible for the fault tolerance of the service itself. Currently, Spark does not have any single point of failure in standalone mode, which is implemented with zookeeper, which is similar to

presentation layer only knows the coarse-grained interfaces provided by the service layer, and the service layer knows only a series of workable protocols that deal with the essence of the details: transaction, resource management, coordination, and data messaging.Service layer in real life examplesThe emergence of SOA, consistent with the advent of the service layer, strengthens the concept of the service layer and makes him more attractive.

In the final analysis, the object detection is not good at present, or because there are a large number of very small objects exist itself, and small objects detection is difficult because: Small objects because small, the internal scale difference is very large (multiples, because the denominator is very small, one will be very large), the detector needs a strong scale-invariance ability, and CNN on its design itself is not Scale-invariance; Small objects it
