In today's Forums, kupior is looking to do some Heap manipulation: "Is there any way to directly manipulate the heap from within a java program? I am working on the standard multithreaded java application with multiple threads operating on a lot of small (serializable) objects. In order to account for a possible system failure, I would like to periodically serialize and store all of the data for backup purposes. I want the minimum possible delay to normal operations within the program. I dont want concurrency problems corrupting data (gradual backup on live data is not feasible in this case). If it is [ever] possible, I would like to clone the heap then have another thread back up all of the needed data within the heap."

In Calculate new image width and image height, lmhoa says: "I'm working on an application that reads a image from file, applies AffineTransform including scale, shear and rotate parameters and then saves it to another image file. But the new image is lost some when I keep it the same size as the original image. Question: Is there any ways to calculate new image size which is depend on scale, shear and rotate parameters?"
