javascript - Looping through array and removing items, without breaking for loop -

i have following loop, , when use splice() remove item, 'seconds' undefined. check if it's undefined, feel there's more elegant way this. desire delete item , keep on going. for (i = 0, len = auction.auctions.length; < len; i++) { auction = auction.auctions[i]; auction.auctions[i]['seconds'] --; if (auction.seconds < 0) { auction.auctions.splice(i, 1); } } the array being re-indexed when .splice() , means you'll skip on index when 1 removed, , cached .length obsolete. to fix it, you'd either need decrement i after .splice() , or iterate in reverse... var = auction.auctions.length while (i--) { .... } this way re-indexing doesn't affect next item in iteration, since indexing affects items current point end of array, , next item in iteration lower current point.

google app engine - How can I modify the property of ndb model through a webapp2 handler in python -

i have python file , html file interact each other through jinja2 environment in manner similar 1 in this tutorial . the following code controls interaction between html file , python file: class mainpage(webapp2.requesthandler): def get(self): submission_query = submission.query().order(-submission.score) submissions = submission_query.fetch(10) template_values = { 'submission' : submission, 'submissions' : submissions, } template = jinja_environment.get_template('index.html') self.response.write(template.render(template_values)) app = webapp2.wsgiapplication([ ('/', mainpage), ('/create', createsubmmission), ('/voteup', voteup), ], debug=true) i have ndb model follows: class submission(ndb.model): username = ndb.stringproperty() placename = ndb.stringproperty() link = ndb.stringproperty() score = ndb.integerproperty()

Sum of sine functions in Matlab -

i have create function following definition: function [ s1,s2,sums ] = sines( pts,amp,f1,f2 ) the output argument s1 row vector length (number of elements) equals pts. elements of s1 values of sine function when given equally spaced arguments start @ 0 , extend through f1 periods of sine. amplitude of sine wave equals amp. vector s2 same s1 except s2 contains f2 periods. vector sums sum of s1 , s2. if f2 omitted, should set value 5% greater f1. if f1 omitted also, should set 100. if amp not provided, should default 1. finally, if pts omitted well, should set 1000. have done following: function [ s1,s2,sums ] = sines( pts,amp,f1,f2 ) if nargin == 3 f2 = f1 + (f1*0.05); elseif nargin == 2 f1 = 100; f2 = f1 + (f1*0.05); elseif nargin == 1 amp = 1; f1 = 100; f2 = f1 + (f1*0.05); elseif nargin == 0 pts = 1000; amp = 1; f1 = 100; f2 = f1 + (f1*0.05); end t = 0:pts-1; s1 = amp * sin( 2*pi*f1.*t ); s2 = amp * sin( 2*pi*f2.*

c++ - OpenAL ALUT sound error -

Image
after looking on internet, not find answer issue. creating game university assignment , marks , have decided implement sound game. i using openal alut .dll's. here errors get. above error list me declaring sound , things need sound. it looks you've forgot link against libraries. error don't seem have openal though. try , find out definition of tle::new3dengine , add library additional dependencies ( project -> linker -> input ). should add %(additionaldependencies) rid of getsystemmetrics linking error.

Efficient one-liner in Julia to calculate "running" sums? -

is there efficient way following in julia in 1 line of code? foldl((prev, x)-> [prev; prev[end] + x] , 0, block_lengths) for example, block_lengths = [2, 2, 2, 2, 3] the desired output is [0, 2, 4, 6, 8, 11] (i presume way used foldl above inefficient, because i'm concatenating vector , integer @ each iteration.) iiuc, can use cumsum : julia> block_lengths = [2, 2, 2, 2, 3]; julia> cumsum(block_lengths) 5-element array{int32,1}: 2 4 6 8 11 julia> [0; cumsum(block_lengths)] 6-element array{int32,1}: 0 2 4 6 8 11 which should o(n).

class - __init__ Constructor in Python -

i trying write constructor class "block" stores coordinates of center of block (either separate x- , y-coordinates or pair of numbers) , width , height of block. problem having writing init can either take tuple of coordinates x,y or individual numbers x , y. here have far: def __init__(self,(x,y),height,width): use keyword arguments: class blocks(object): def __init__(self, center=none, x=none, y=none, height=0, width=0): if center none: # x , y must set if x none or y none: raise typeerror('you must either specify center or both x , y') else: # center set, x , y must not if x not none or y not none: raise typeerror('you must either specify center or both x , y') x, y = center # here have x , y set now can use blocks(center=(10, 20)) or can use blocks(x=10, y=20) . height , width have defaults, can overridden. the a
