a phone has many messages. an email address has many messages. a message either belongs phone, email, or neither. belongs_to association optional. the following associations seem work fine these relationships: phone model has_many :messages email model has_many :messages message model not have belongs_to :phones, :email is okay or there proper way specify "can_belong_to" relationship? it correct unidirectional relation. using both called "curcular dependency" purists , may cause problems when using validates_associated . from other side using has_many :messages may not enough when want retrieve phone information 1 message. matter of convenience.

okay, have integer variable in application. it's value of color, being set color picker in preferences. now, need use both color , darker version of color might be. now know in standard java there color.darker() method, there doesn't seem equivalent in android. know of equivalent or workarounds? the easiest, think, convert hsv, darkening there, , convert back: float[] hsv = new float[3]; int color = getcolor(); color.colortohsv(color, hsv); hsv[2] *= 0.8f; // value component color = color.hsvtocolor(hsv); to lighten, simple approach may multiply value component > 1.0. however, you'll have clamp result range [0.0, 1.0]. also, multiplying isn't going lighten black. therefore better solution is: reduce difference 1.0 of value component lighten: hsv[2] = 1.0f - 0.8f * (1.0f - hsv[2]); this entirely parallel approach darkening, using 1 origin instead of 0. works lighten color (even black) , doesn't need clamping. simplified to: hsv[2] = 0.2f...

i working on project on svn. not have access internet few days, , working on project. is there way make clone of repository on local machine, commit changes it, , when gain access internet "push" them onto shared repository? thinking in terms of mercurial here, worth migrating completely?! your problem sounds me the use case git-svn : set git repo: git svn clone http://svn.example.com/project/trunk while being online, commit changes svn before going offline, git svn rebase git repo in sync svn repo while being offline, commit git repo using git commit when getting online again, git svn dcommit push changes svn repo i'm using workflow daily! you 2 huge advantages doing so: your complete svn history backed in git repo , in every git repo gets cloned one while being offline, can view commit messages, checkout other branches, etc.

if have array of points (x,y,z) , given single point (x,y,z), code use determine if point resides within shape defined array? i drawing blank on one... i'm using c# edit thanks responses guys, comments have found link ( http://alienryderflex.com/polygon/ ) explains process quite well. thanks! fyi: bool pointinpolygon() { int i, j=polysides-1 ; boolean oddnodes=no ; (i=0; i<polysides; i++) { if (polyy[i]<y && polyy[j]>=y || polyy[j]<y && polyy[i]>=y) { if (polyx[i]+(y-polyy[i])/(polyy[j]-polyy[i])*(polyx[j]-polyx[i])<x) { oddnodes=!oddnodes; }} j=i; } return oddnodes; } it'll need work, thats guts of it. thanks again use point know outside shape, , check if line point given point passes through surfaces of shape. if passes through odd number of surfaces, given point inside shape.
