[ "Alfresco space user permissions", "I have an alfresco folder (PARENT_FOLDER) with more than 300 subfolder, and I want to grant consumer role to certain group (GROUP1) and certain subfolder (PARENT_FOLDER/FOLDER1), and consumer role to other group (GROUP2) and all subfolder.\n\nAll subfolders have \"Inherit Parent Space Permissions\" activated, and parent folder has this space user permissions:\n\n\nOWNER_USER: Coordinator\nGROUP2: Consumer\n\n\nThe PARENT_FOLDER/FOLDER1 has:\n\n\nGROUP1: Consumer\n\n\nWith this configuration:\n\n\nGROUP2 can access to PARENT_FOLDER and all subfolders.\nGROUP1 only to objects contained in PARENT_FOLDER/FOLDER1 (by id), but cannot access to objects from their path, and whit a CMIS client cannot make a getParent(), etc. To make it possible, PARENT_FOLDER must have GROUP1: Consumer grant, and in this case , GROUP1 could access all subfolders.\n\n\nI think the solution is revoke \"Inherit Parent Space Permissions\" and specify this user space permissions:\n\n\nPARENT_FOLDER:\n\nOWNER_USER: Coordinator\nGROUP1: Consumer\nGROUP2: Consumer\n\nPARENT_FOLDER/FOLDER1:\n\nOWNER_USER: Coordinator\nGROUP1: Consumer\nGROUP2: Consumer\n\nOther subfolders differents to PARENT_FOLDER/FOLDER1:\n\nOWNER_USER: Coordinator\nGROUP2: Consumer\n\n\n\nbut make it is very difficult because I can't select many subfolders and change their user permissions.

[ "Better way of sending bulk requests to a remote API with Django Celery?", "I have users table with 24K users on my Django website and I need to retrieve information for each of my users by sending a request to a remote API endpoint which's rate limited (15 requests/minute).\n\nSo my plan is to use the Celery periodic tasks with a new model called \"Job\". There are two ways in my perspective:\n 1. For each user I will create a new Job instance with the ForeignKey relation to this user.\n 2. There will be a single Job instance and this Job instance will have a \"users\" ManyToManyField field on it.\n\nThen I'll process the Job instance(s) with Celery, for example I can process one Job instance on each run of periodic task for the first way above. But..there will be a huge amount of db objects for each bulk request series...\n\nBoth of them seem bad to me since they are operations with big loads. Am I wrong? I guess there should be more convenient way of doing so. Can you please suggest me a better way, or my ways are good enough to implement?" ]

[ "When autowiring use would be beneficiary with example", "I have recently learned concept of autowiring in spring. When I was trying to understand in which particular scenarios spring autowiring can be useful \nI came up with the below two reasons from one of the questions asked in our stakoverflow forum. \n\n1.I wanted to read values from a property file and inject them into a bean. Only way I could figure out how to do this at start up of my app was to \nwire the bean in XML (and inject the properties.) I ended up using the \"byName\" attribute (because the bean was also marked as @Component) and then \nused @Autowired @Qualifier(\"nameIChose\") when injecting the bean into another class. It's the only bean I've written that I wire with XML.\n\n2.I've found autowiring useful in cases where I've had a factory bean making another bean (whose implementation class name was described in a system \nproperty,so I couldn't define the all wiring in XML). I usually prefer to make my wiring explicit though;\n\nCan any body please give me some code snippet example of the above situations that would make my understanding of autowiring more clearer?" ]

The reason I believe for it to be a scaling issue is because it is completely vertical and does move up and down correctly when I walk closer or further from the camera.\n\nThis is the main body of code for this operation:\n\nSkeletonPoint headPos = currentSkeleton.Joints[JointType.Head].Position;\nSkeletonPoint floorPoint = getSkeletonFloorPoint(headPos, floorPlane); \nCoordinateMapper mapper = new CoordinateMapper(KinectSensor);\n\nColorImagePoint colorHeadPoint = mapper.MapSkeletonPointToColorPoint(headPos, ColorImageFormat.RgbResolution640x480Fps30);\nPoint mappedHeadPoint = new Point(colorHeadPoint.X, colorHeadPoint.Y);\n\n\nColorImagePoint colorFloorPoint = mapper.MapSkeletonPointToColorPoint(floorPoint, ColorImageFormat.RgbResolution640x480Fps30);\nPoint mappedFloorPoint = new Point(colorFloorPoint.X, colorFloorPoint.Y);\n\n\ndrawUserPosition(userPos, mappedHeadPoint, mappedFloorPoint);\n\n\nThis the method which computes the floor point based on the head position:\n\nprivate SkeletonPoint getSkeletonFloorPoint(SkeletonPoint skeletonHeadPos, Tuple<float, float, float, float> floorPlane)\n{\n Point3D headPos = new Point3D(skeletonHeadPos.X, skeletonHeadPos.Y, skeletonHeadPos.Z);\n Point3D pointOnPlane = new Point3D(0, (double) -(floorPlane.Item2 / floorPlane.Item4), 0);\n Vector3D planeNorm = new Vector3D(floorPlane.Item1, floorPlane.Item2, floorPlane.Item3);\n Vector3D planeToHead = Point3D.Subtract(headPos, pointOnPlane);\n\n double dist = Vector3D.DotProduct(planeNorm, planeToHead);\n Point3D floorPoint = Vector3D.Add(Vector3D.Multiply(-dist, planeNorm), headPos);\n\n SkeletonPoint skeletonFloorPoint = new SkeletonPoint();\n skeletonFloorPoint.X = (float) floorPoint.X;\n skeletonFloorPoint.Y = (float) floorPoint.Y;\n skeletonFloorPoint.Z = (float) floorPoint.Z;\n\n return skeletonFloorPoint;\n}\n\n\nThis sets the line position:\n\nprivate void drawUserPosition(Line userPos, Point headPoint, Point floorPoint)\n{\n userPos.X1 = headPoint.X;\n userPos.Y1 = headPoint.Y;\n userPos.X2 = floorPoint.X;\n userPos.Y2 = floorPoint.Y;\n\n}\n\n\nThis is the XAML for the canvas:\n\n<Canvas>\n <kt:KinectSkeletonViewer \n KinectSensorManager=\"{Binding KinectSensorManager}\"\n Visibility=\"{Binding KinectSensorManager.ColorStreamEnabled, Converter={StaticResource BoolToVisibilityConverter}}\"\n Width=\"{Binding ElementName=ColorViewer,Path=ActualWidth}\"\n Height=\"{Binding ElementName=ColorViewer,Path=ActualHeight}\"\n ImageType=\"Color\" />\n\n <Line X1=\"0\" Y1=\"0\" X2=\"0\" Y2=\"0\" Name=\"userPos\" Stroke=\"Red\" StrokeThickness=\"2\" />\n\n</Canvas>\n\n\nAs I said, I think the geometry is correct, I just don't have any experience with WPF so I am fairly certain that is where I am going wrong.\n\nThank you for any help, and if there are any details I can provide to make this easier to solve I will be happy to provide them." ]

I just wouldn't want to post it on here because it's quite lengthy.\n\nThanks!\n\nEDIT: I've placed my code on JSfiddle as some people have suggested. You can find it here.
