in routes.rb had resource resources :home_screen_buttons post :update_multiple, :on => :collection end update_multiple helper update_multiple_home_screen_buttons then decided remove resource because need update_multiple method in controller, changed routes.rb to post "home_screen_buttons/update_multiple" it create helper home_screen_buttons_update_multiple instead of update_multiple_home_screen_buttons why has different routing helper name? it makes sense :on => :collection has different helper :on => :member, there other way adding :as => :update_multiple_home_screen_buttons post method same behavior? this how rails this. when match used, maps uri action , creates corresponding helper path controller_action_path when used collection, becomes restful action resource , rails gives logical name relating collection. quoted example here : resources :photos collection 'search' end end generates search_photos_pat...

i want calculate right-tailed probability of chi-squared distribution in c#. excel can calculation using following code = chisq.dist.rt(100,4) where 100 chi-squared , 4 degree of freedom. i want use function in c# calculation; tried adding reference "microsoft.office.interop" not find way use ! i came across topics of how use c# formulations in excel , results in excel, unfortunately not need; need calculation in c# , results in c#. if wanting calculation similar excel calculation, should consider @korolewi's suggested comment. if have use excel's engine, can what previous poster suggested, require instance of excel installed on web server , launch excel each time code executed, etc. bad practice , unsupported microsoft use third party tool aspose.com's cells. set formula, calculate it, , value wookbook without opening excel on server.

in java project need unmarshal xml file in order list of objects. the unmarshalling works fine problem encontourned when content of file modified. in fact in project can add new contents file clicking on "addbuton" when want unmarshal time same file (after modification) old list of objects without last elements (i have added file). i verified physical xml file on disk , found last content added. noticed way last list of objects close appli , reopen again, unsuitable. here piece of code: //classe1.java file inifile = new file(proprietesperle.getrepref() + "referential.xml"); fileinputstream fs = = new fileinputstream(inifile); ref = referentiel.unmarshal(fs); treemap map = referentielutil.getapplication( ref ); ... //classe2.java treemap map = new treemap(); list listpl = app.getpl(); //this list unmarshalled xml file listiterator itpl = listpl.listiterator(); while (itpl.hasnext()) { pl pl = (pl)itpl.next(); map.put(pl...

let's assume have drawn n=10000 samples of standard normal distribution. now want calculate entropy using histograms calculate probabilities. 1) calculate probabilities (for example using matlab) [p,x] = hist(samples,binnumbers); area = (x(2)-x(1))*sum(p); p = p/area; (binnumbers determined due rule) 2) estimate entropy h = -sum(p.*log2(p)) which gives 58.6488 now when use direct formula calculate entropy of normal data h = 0.5*log2(2*pi*exp(1)) = 2.0471 what do wrong when using histograms + entropy formula? thank help!! you missing dp term in sum dp = (x(2)-x(1)); area = sum(p)*dp; h = -sum( (p*dp) * log2(p) ); this should bring close enough... ps, careful when take log2(p) might have empty bins. might find nansum useful.

the php warning, "strict standards: declaration of x should compatible y" warns if write code like: class { function foo($x) { .. } } class b extends { function foo() { .. } } this sensible, because object reference " $a " think a , may @ runtime turn out b , dynamically dispatched method call $a->foo(3) may end calling b::foo() wrong number of arguments. my question is: why same warning applied static methods, not dynamically dispatched? class x { static function bar($x) { .. } } class y extends x { static function bar() { .. } } in example, function y::bar() not override x::bar() , there no reason trigger warning, php still does. why? just in java, can call static methods on instance too. there still room confusion.

i trying make color magnitude diagram similar to: i have 3 arrays contain exact same number of values. x1 = b-v (-.5 2) x2 = temperature. (30,000 3000) , needs log scale y1 = magnitude (varies based on others) the x1 , x2 , , y1 arrays linked, , plot them in scatterplot. my code: #plots x1 = bv_array #b-v x2 = t_array #temperature y1 = vavg_array #magnitude fig = plt.figure() ax1 = fig.add_subplot(111) #ax1.xlim(-.5,2) ax1.plot(x1, y1,'b--') ax2 = ax1.twiny() ax2.plot(x2, y1, 'go') ax2.set_xlabel('temperature') ax2.invert_xaxis() #ax2.xscale('log') #plt.xscale('log') #plt.scatter(x,y) #plt.scatter(bv_array, vavg_array, s = 1) plt.gca().invert_yaxis() plt.show() if i'm understanding correctly, should able pick single point on right hand edge of graph axes should aligned, , matplotlib take there. ax1 = fig.add_subplot(111) ax1.xlim(-.5,2) # set in axis 1 coords ax1.plot(x1, y1,'b--...

what best way return or pass strings in char pointers in c? i have function looks this: char *test_getcwd(){ char *cwd; char *ret; if ((cwd = getcwd( ret, pathconf(".",_pc_path_max) )) == null){ perror ( "error on calling getcwd() function" ); }else if (__include_level__ == 0){ puts( cwd ); } free( cwd ); return ret; } should change to: int test_getcwd(const **pass){ char *cwd; char *ret; if ((cwd = getcwd( ret, pathconf(".",_pc_path_max) )) == null){ perror ( "error on calling getcwd() function" ); }else if (__include_level__ == 0){ puts( cwd ); } free( cwd ); *pass = ret; return 0; } or leave or maybe change else? similar questions may have been asked goal find best practice it. the first argument getcwd must either null or pointer existing buffer. clue how design routine. either: accept pointer existing buffer parameter,...

i bit more mobile webdev , searching books or screencasts topic. of course found dozents, don't know choose. does make sense read books design part in it, although won't ever make design, implement them? any suggestions out there, there must have reads? thanks help! edit: searching books, cover themes media-queries , on. have put designs in web pages , improve skills making them mobile friendly. i've found smashing magazine helpful: http://mobile.smashingmagazine.com/ if prefer book format, mobile book collection of articles related mobile design , development , quite good: http://www.the-mobile-book.com/ has chapter on responsive design patterns might find useful.
