we have azure mobile app application using .net client library of azure mobile apps. whenever pullasync, client pulls down data in batches of 50 records per http request/response. pushasync sends one patch http request per modified row . our use case involves update of potentially hundreds of rows, slow. is possible tell azure mobile apps batch several updates 1 http request during push? another (related) issue push sends entire row modified, not modified fields. increases json size unnecessarily. possible tell azure mobile apps include modified columns in json? no, "batch update" functionality not directly available. can simulate custom api, have careful on sequencing. the push needs send fields - pretty requirement of wire protocol.

i have 4x4 transformation matrix. however, after trying out transformation noticed movement and rotation of y axis going opposite way. rest correct. i got matrix other api difference of coordinate system. so, how can flip axis of transformation matrix? if translation can add minus sign on y translation, have no idea opposite rotation of 1 axis since rotation being represented in same 3x3 area. thought there might way affect both translation , rotation @ same time. (truly flipping axis) edit: i'm pretty sure operation you're looking changing coordinate systems while maintaining z-up or y-up. in case, try setting elements of second column (or row) of matrix inverse. this question better math stackexchange. first, a helpful read on rotation matrices . the first problem matter of rotation order. assuming xyz rotation order. know rotation matrices each axis follows: given matrix derived same rotation order, resulting matrix follows, alpha x angle, beta y ...

struct node { int val; struct node *left, *right; }; // stack type struct stack { int size; int top; struct node* *array; }; struct stack* createstack(int size) { struct stack* stack = (struct stack*) malloc(sizeof(struct stack)); stack->size = size; stack->top = -1; stack->array = (struct node**) malloc(stack->size * sizeof(struct node*)); return stack; } what statement do? stack->array = (struct node**) malloc(stack->size * sizeof(struct node*)); what memory representation of it? stack->array = (struct node**) malloc(stack->size * sizeof(struct node*)); struct node** returns pointer pointer (to stack) stack->size amount of items of stack sizeof(struct node*) size of pointer node. so creates array of pointers, each pointer points 1 element within stack.
