i'm working on game obscures part of image, player guesses what's hidden , obscured part revealed, player can see if guessed correctly. at moment draw black box above obscured part, nice if pixelate obscured area huge pixel size, decrease pixelation size until image visible, in animation. is possible somehow utilize android's support animations (i have used in 1 game, animate on screen stuff), or need implement entirely on own using kind of timer , drawing on canvas myself? or there handy me? hint possible solution: use bitmapfactory sample of image that's smaller original, , blow create "pixelated" version. see: http://developer.android.com/reference/android/graphics/bitmapfactory.options.html#insamplesize

i haven't used ruby trying learn. found 'schema.db' file looks generated active record module. i trying figure out how convert file sql can import database? active record generate schema.rb , represents current state of database (useful getting quick idea of attributes each model has). it used when deploying new instances of app, rather replaying whole migration history (and how test database created) as example, here's how can deploy production database: rails_env=production rake db:create db:load

is there common way test complex functions several parameters nunit? think hard or impossible test every condition. i'm afraid combination of parameters isn't expected in function not expected in test. so expected condition not fail unexpected. thanks this shouldn't hard test @ all. if is, method isn't designed testability, , code smell tells you need refactor it. i tend write tests in these cases follows (others may have better suggestions): does work intended when appropriate parameters passed? does throw expected exceptions when think should? (argumentnullexception, etc.) for each parameter, happens when pass null, minimum , maximum. (this can extensive, depending on number of arguments.) if method takes lot of parameters, consider refactoring take object information on it, can encapsulate rules in object, , pass object method.

i want use regular expression following thing ( extracted part i'm in trouble in order simplify ): character 1 5 first characters, "underscore", digits, "underscore", digits or dot. with restriction on "underscore" should give that: ^([^_]{1,5})_([\\d]{2,3})_([\\d\\.]*)$ but want allow "_" in 1-5 first characters in case still match end of regular expression, example if had somethink like: to_to_123_12.56 i think linked eager problem in regex engine, nevertheless, tried lazy stuff explained here without sucess. any idea ? i used following regex , appeared work fine task. i've replaced initial [^_] . . ^.{1,5}_\d{2,3}_[\d\.]*$ it's best replace final * + too, unless allow nothing after final '_'. , note final part allows multiple '.' (i don't know if that's want or not). for record, here's quick python script used verify regex: import re strs = [ "a_12_1", ...
