there have been many similar questions on mutual dependencies, each leaves me unsure own design. i writing chess program learn scala. close relationship between board , pieces makes me wonder if piece object should contain reference board belongs to. approach when wrote chess program in java. however, means board not defined until has pieces, , vice-versa. codependency no problem if board instance variable can add pieces build board, goes against immutability. related: the approach here seem suggest defining rules of piece movement in board object: https://gamedev.stackexchange.com/questions/43681/how-to-avoid-circular-dependencies-between-player-and-world the highest voted answer here has similar suggestion: two objects dependencies each other. bad? the selected answer above link different -- moves mutual dependency class definitions interfaces. don't understand why better. the design here mirrors current approach : https://sourcemaking.com/refactoring/change-bid

my problem rotate ellipsoid model around origin. i'm using rotation matrices answer doesn't ok. can tell me problem is? below code. 1st defined region , grid size. alpha, beta, gamma rotations around x,y,z axis. calculate ellipsoid radii's in new coordinate (rotated coordinate) check point point if agree ellipsoid formula define epsilon matrix goal based on points locations. @ end plot epsilon matrix xy,xz,yz planes. works alpha,beta,theta =0 , 90 degrees other angles there's not resealable answer. think mistake? fyi: code part of fdtd method maxwell's equations solver. thanks, nx=209; ny=209; nz=209; x_lower=1 ; y_lower=1 ; z_lower=1 ; x_upper=nx ; y_upper=ny ; z_upper=nz ; dz=2.366863905325444e-008 ; dy=2.366863905325444e-008 ; dx=2.366863905325444e-008 ; k_mid=(nz+1-1)/2+1; j_mid=(ny+1-1)/2+1; i_mid=(nx+1-1)/2+1; x_cyto=0 ; y_cyto=0 ; z_cyto=0 ; r_cell=2e-6; alpha=0; beta=0; gamma=0; temp_1=1.334 ; temp_2=1.35; a_cyto=1e-6 ; b_cyto=1e-6 ; c_cyto=1e-6

i have been designing website year (self taught html, css , javascript) on last project experience designing , code structure issues. i start laying out entire website divs (i add background-color create boxes layout website) , start writing html/content. javascript, write needed. i wondering what's efficient way approach webdesign workflow , avoid extra-work such experienced on previous project. should start writing html, css , finish javascript? start wire framing on pen , paper, or whiteboard if available. after you'll wont have structures problems anymore. you can put out layout gives idea how project , catch lot of development/design problems, html , css simultaneous. once reached point of golden door not golden inside. you'll add js, , change/add css of necessary. should keep question in mind while doing js "do need or css/html too".

i have following linked list: struct node { int d; struct node *next; }; int main() { struct node *l = 0; struct node *k = l; k = malloc(sizeof(struct node)); /* l->d = 8; */ return 0; } why commented code wrong use? don't understand why memory isn't allocated node ``l points since k points same node l , used k -pointer allocate memory it. let's take apart. @ comments struct node{ int d; struct node * next; }; int main(){ struct node * l = 0; // l = 0 (or null) struct node * k = l; // k=l=0 k = malloc(sizeof(struct node)); // k=<some address allocated> /* l->d = 8; // l still 0 */ return 0; } so commented code trying dereference null pointer.

i use image loading library (picasso) image loading/display remote images, , works well. however, local resources (mostly smaller image icons) i've been putting image directly in xml (via src="@drawable/image_name"). should using picasso (or glide, etc) load these smaller local images? if so, should both lists (shown via recyclerview) , 1 off icons? loading these local resources w/o loader working, improve perf if possible. thanks! standard practice local density specific resources included apk load them via resources, either including them src or background in xml or using resources#getdrawable(). usually image loading library unnecessary local resources because local resources tend small, fast decode , in memory in resources cache managed android. that said, if think have performance problem, measure! if looks particular image heavy activity or fragment slow start because of layout inflation time, may want experiment using image loading library reso
