Android camera2 CONTROL_AE_MODE_OFF and CONTROL_AF_MODE_CONTINUOUS_PICTURE -

i want set exact sensor_exposure_time , still have continuous_picture focus. according android documentation, set sensor_exposure_time need set control_ae_mode_off . in mode, can't set control_af_mode_continuous_picture , because works if control_ae_mode != off . so, looks it's impossible. camera fv-5 have continuous_picture focus , manual set sensor_exposure_time . how possible? device nexus5 you can indeed set control_mode auto (and control_af_mode whatever want) yet still set control_ae_mode off . i know documentation doesn't read allows this, time separate control of 2 on nexus 5. control_mode seems enforce overall control when set off , merely "suggests" when set auto . is, can override each of af/ae/awb using *_control_mode settings in latter case, not former.

java - How to configure mvn/Jrebel/wtp/gwt/eclipse to work smoothly with changes on the service interface -

i started investigate guice-rf-activities artifact new maven gwt plugin thomas broyer. i played little bit code , added function on greetingservice on serverside. followed down path , added required bits , bytes until code calling either greetserver or insultserver method. i found, simple sdm recompile did not make method available on server. restarting tomcat did not either. saving file in eclipse did not trigger compile properly. in end, running full module compile did trick. i see problem, change on service potentially give time coffee on large projects. there "trick", did not do, or complexity of requestfactory code generation heavy, cannot use sdm + jrebel or server restart change service interfaces? update: way described thomas (thanks!) works, if plan start tomcat maven tomcat target. update2: described launcherdir approach wtp/eclipse/mvn/jrebel run. if want use eclipse wtp tomcat launcher and, do, jrebel, compile server-classes on fly, jrebel

angularjs - What is the difference between ngInclude and ngRoute -

i start using ngroute because ngrouter talk here lately started realizing nginclude working fine me , i'm wondering why seems using ngrouter instead. both load templates (or fragments) , can attach controller either or. benefit using ngroute can use href load template? don't mind using ng-click , changing nginclude value true. seems easier me i'm sure i'm missing something. the point of using router assign urls pages of app. can refresh current page, or send link current page friend, or bookmark current page, , land on that page, instead of landing on home page of app.

haskell: filtering Strings with a certain symbol e.g '!' in a List? -

i have list of strings : ["1*1", "ab!c", "cde2", "efghi!"] want sort out every string '!' . first idea : filter (map elem '!' (list)) list string map elem '!' (list), thats not working because checkups string , not elements of strings in list... thanks help! you mapped much. filter ('!' `elem`) list should work you.... explanation: you have list of strings [string] . string list of chars, because string = [char] ... so have list of lists. [[char]] since elem works checking if single element exists in list, can call elem on each list item outer list.

python - RK4 giving wrong result -

i'm trying numerically solve simple second order de x'' = -x. used new variable x'=v, have 2 equations. while seems simple, somehow produces result that's far of correct result. def f(x): return -x def rk4(f=f,h=2*pi/100,x0=1,v0=0,t0=0,n=100): '''rk4''' v=[v0] x=[x0] in range(n-1): v1= h*f(x[-1]) x1= h *(v[-1]) v2= h*f(x[-1]+1/2*x1) x2= h *(v[-1]+1/2*v1) v3= h*f(x[-1]+1/2*x2) x3= h *(v[-1]+1/2*v2) v4= h*f(x[-1]+x3) x4= h *f(v[-1]+v3) v.append(v[-1]+1/6 *(v1+2*v2+2*v3+v4)) x.append(x[-1]+1/6 *(x1+2*x2+2*x3+x4)) return x,v the weird thing if use rk45 coefficients, works fine. idea on wrong? def rk4(f=f,h=2*pi/100,x0=1,v0=0,t0=0,n=100): '''rk4''' v=[v0] x=[x0] in range(n-1): v1=h*f(x[-1]) x1=h *v[-1] v2=h*f(x[-1]+1/4*x1) x2=h *(v[-1]+1/4*v1) v3=h*f(x[-1
