问题 Hi am developing a load balancing algorithm in java. In my system there will be one mater node and list of slave nodes, Where the master node will distribute the incoming request to one of its slave node. I want to find the C.P.U load (percentage of C.P.U utilized) in each of the slave nodes. So that the master node can effectively distribute the request to one of its least loaded slave node. Can any one please suggest me how can we find it. The getSystemLoadAverage() method in JMX can be

问题 I'm doing a load test on user signup with the same email address for a webservice and the first 10 users which connect simultaneously will always register.

问题 I've used this tutorial to create an app with a table view that is populated using an NSMutableArray. Now I'd like to add the functionality to add additional items to the array and save/load them. I've customized the Fruit class to look like this: #import <UIKit/UIKit.h> @interface Fruit : NSObject { NSString *name; NSString *instructions; NSString *explination; NSString *imagePath; } @property(nonatomic,copy) NSString *name; @property(nonatomic,copy) NSString *instructions; @property

问题 I used to have Matlab and loaded all txt-files from directory "C:\folder\" into Matlab with the following code: myFolder = 'C:\folder\'; filepattern = fullfile(myFolder, '*.txt'); files = dir(filepattern); for i=1:length(files) eval(['load ' myFolder,files(i).name ' -ascii']); end If C:\folder\ contains A.txt, B.txt, C.txt, I would then have matrices A, B and C in the workspace. The code doesn't work in octave, maybe because of "fullfile"?. Anyway, with the following code I get matrices with

问题 I want to resize an image parent to the same size of the image, when the images are loaded.

问题 try { x = session.load(...); y = x; } catch(Exception e) { //do something } If the key is not present, will load(...) throw an exception right away will return a proxy and then throw an exception when the object is trying to be obtained from the db later? Also, in the code above, if the execution reaches the assignment y = x, is it guaranteed that at that point, x is not null? Are there situations where x can be null at that point? 回答1: In short: x will not be null after the load, so neither
