simple question: <virtualhost *:80> servername notes.example.com documentroot /var/www/notes <directory "/var/www/notes"> require granted options +indexes </directory> </virtualhost> on first sight works putting: <virtualhost *:80> servername notes.example.com documentroot /var/www/notes </virtualhost> so why need <directory> statement anyway? i've found several examples on web of using <directory> or <proxy> thing , others putting settings under <virtualhost> branch. because can define particular parameters particular directories. you <directory "/var/www/notes/private"> options -indexes <directory> or similar. documentroot work itself, if want add directory options, you'll need use directory tag.

why getting error in code, seems normal me. declare 'hills' variable still getting error "expected declaration" both 'hills' , 'bg'. var bg = skspritenode(imagenamed: "sky") bg.position = cgpointmake(bg.size.width / 2, bg.size.height / 2) self.addchild(bg) var hills = skspritenode(imagenamed: "hills") hills.position = cgpointmake(hills.size.width / 2, 300) self.addchild(hills) i suspect reason expected declaration message have placed code inside of class without putting inside of method. example below compiles, gives same error seeing if not included inside of setup method: class mynode: skspritenode { func setup() { var bg = skspritenode(imagenamed: "sky") bg.position = cgpointmake(bg.size.width / 2, bg.size.height / 2) self.addchild(bg) var hills = skspritenode(imagenamed: "hills") hills.position = cgpointmake(hills.size.width / 2, 300)

i found several topics discussed dynamical creating of single variables in loops bad practice , better use dictionary. in case don't need create them dynamically, want access them in loop. i don't want use dictionary them, because these variables used in lot of places in code, , in 1 place need such dynamic access. idea example: car_pos = 1; man_pos = 10 car_vel = 100; man_vel = 5 elm in ['car', 'man']: elm_pos = elm + '_pos' elm_vel = elm + '_vel' # want values of elements such names here print(elm_pos, elm_vel) # desired output: # (1, 100) # (10, 5) variable names terrible way relate pieces of information. there nothing linking man_pos , man_vel except both happen start man . other totally separate. python has better ways of bundling elements these together. in case, man , car should objects attributes pos , vel . class thing: def __init__(self, pos, vel): self.pos = pos self
