i'm new java , love stream api. got loop: list<filetree> expanded = new arraylist<>(); for(filetree item : tree){ if(item.gettype().equals("tree")){ expanded.addall(gettreeofsubstudpackage(item.getname())); } else{ expanded.add(item); } } and wonder if converted neat stream. first guess following: tree.stream().map(filetree -> { if(filetree.gettype().equals("tree")){ return gettreeofsubstudpackage(filetree.getname()); } else{ return filetree; } }).collect(collectors.tolist()); it compiles fine. recommended, have implemented no-go or there nicer way? , last not least: there overhead in .stream() make improvement worthless? appendix list<filetree> gettreeofsubstudpackage(...){ //... } class filetree { private string name; private string type; private string mode; private string id; //... public getter , setter ... } you need map ...

i troubling save records in update set statement within php. im using javascript update record on submit. see below code: /* update record */ $(document).on('submit', '#emp-updateform', function() { $.post("update.php", $(this).serialize()) .done(function(data){ $("#dis").fadeout(); $("#dis").fadein('slow', function(){ $("#dis").html('<div class="alert alert-info">'+data+'</div>'); $("#emp-updateform")[0].reset(); $("body").fadeout('slow', function() { $("body").fadeout('slow'); window.location.href="home.php"; }); }); }); return false; }); /* update record */ note above method retrieving file update.php update set statement lies. see code: if(isset($_post)){ ...

in python i'm using numpy package math matrices. in code below i'm trying calculate new matrix orignal. xfactors , yfactors both 3x3 matrices. size = self.matrix.shape x in range(1, size[0] - 1): y in range(1, size[1] - 1): submatrix = self.matrix[x-1:x+2, y-1:y+2] newx = (xfactors * submatrix).sum() newy = (yfactors * submatrix).sum() self.newmatrix[x-1][y-1] = newx + newy my problem code inefficient. tested te code 500x500 matrix , takes 2 seconds. have ideas how can optimize code? if xfactors , self.matrix both numpy.array , not numpy.matrix (in other words if using element-wise multiplication , not matrix multiplication in calculating newx , newy), should same thing lot faster: from scipy.signal import convolve2d self.newmatrix = convolve2d(self.matrix, xfactors + yfactors, mode='valid') in original code, not stated xfactors , yfactors square. if weren't 1 need make them square repeating them n...

i'm new docker world, , understand docker not vm (but sort of user space isolation). i wondering happen if install driver on host os. let's have driver hooks syscall open (it's not i'm doing, example made question) , writes "open" every time called. will see open syscalls processes inside docker? same process call outside of docker?

i have 3d model of 10km x 10km topographic map i've imported sketch-up , model bunch of x,y,z points (where x+ north , z+ straight up, perpendicular ground) i know latitude longitude values of (0,0,0) point. given x,y,z point how latitude longitude values? i need pretty accurate can't assume earth perfect sphere (you can assume it's ellipsoid) for best accuracy need know map projection map drawn in. should able find out map. example in uk ordnance survey maps use osgb36 datum, , projection transverse mercator. projection tells how convert geographic (lat,long datum ellipsoid) coordinates map coordinates (easting , northing) , how reverse calculation, pretty want. if don't know projection, next best thing if find out -- again map, written on -- scale-factor , convergence of projection @ points on map. point there spatially varying difference between map north (the direction north axis points in) , true north (the direction of north pole point, direct...

hello guys have question, how can receive notification when app closed? right when i'm near position i'll receive notification inside app , when i'll left position i'll receive notification, don't know how can receive same notifications when app closed. have used 3 functions: // 1. user enter region func locationmanager(_ manager: cllocationmanager, didenterregion region: clregion) { showalert(title: "enter \(region.identifier)") } // 2. user exit region func locationmanager(_ manager: cllocationmanager, didexitregion region: clregion) { showalert(title:"exit \(region.identifier)") } func showalert(title: string) { let alert = uialertcontroller(title: title, message: nil, preferredstyle: .alert) alert.addaction(uialertaction(title: "cancel", style: .default, handler: { (action) in alert.dismiss(animated: true, completion: nil) })) self.present(alert, animated: true, completion: nil) } thanks lo...

i need memory leaks. ive been staring @ code while , still cant find out leaks. think freeing everything, unnecessarily, there still something. code #include <stdio.h> #include <stdlib.h> struct matrix{ int **data; int rows; int columns; }; struct matrix matrix_op(struct matrix, struct matrix, char); int** _2d_array(int,int); void print_matrix(struct matrix); void _2d_array_free(int**, int); void _scalar_mul(struct matrix*, int); int** _2d_array(int x,int y){ int** arr; arr = malloc(sizeof(int*)*x); for(int = 0; i<x;++i){ arr[i] = malloc(sizeof(int)*y); } return arr; } void _scalar_mul(struct matrix* a, int s){ (int x = 0; x < a->rows; ++x) { (int y = 0; y < a->columns; ++y) a->data[x][y] *= s; } } void _2d_array_free(int** array, int x){ (int = 0; < x; ++i) { free(array[i]); } free(array); } void exit_err(int err, char* message){ fprintf(stderr,mess...
