i using rails 4.1.14 cancancan 1.13.1 , defined granular permissions on model/record level. admins can manage articles users can edit articles authored. to prevent regular users editing specific fields make fields visible in rails_admin depending on role. visible bindings[:object].id == bindings[:view].current_user.roles.include? :admin end i using https://github.com/aasm/aasm gem , created custom actions user can move records new states. but want enable field level permissions depending on user's role / record. can't find docs on cancancan or https://github.com/elabs/pundit pages. does have experience that? you mean admin should allowed edit fields of record, editor allowed change fields x , y? yes, possible in pundit, since integrates strong parameters (which should using anyway). there's example in pundit readme (see: strong parameters). simplified example readme: # post_policy.rb def permitted_attributes if user.admin?

so took coursera course had me work external libraries. 2 .jar files of weekly projects depended upon. i'm not entirely sure how eclipse compiles , runs files, , how links these external libraries -- proper way of organizing this? put copy of each .jar file in each project directory? is there another, cleaner way should organizing this? thanks -- as beginner programmer ok put in each project. consider ongoing work , @ time in future want upgrade new version of these external libraries. have copy everywhere. instead option store them in 1 place , add in classpath in each project. have 1 copy of it, better. now, if , when new version file names might change, still have change classpath of each project. but advise worry these , other such problems later. now, focus on programming related problems rather configuration.

(question prompted comments under answer are there race conditions in producer-consumer implementation? being asked here strictly c language perspective, without concurrency or multi-threading involved.) consider minimal code: #define bufsiz 10 char buf[bufsiz]; void f(int *pn) { buf[*pn]++; *pn = (*pn + 1) % bufsiz; } int main() { int n = 0; f(&n); return n; } question: c "as-if" rules allow compiler rewrite code follows? void f(int *pn) { int n = *pn; *pn = (*pn + 1) % bufsiz; buf[n]++; } on 1 hand, above not change observable behavior of program written. on other hand, f called invalid index, possibly translation unit: int g() { int n = -1001; f(&n); } in latter case, both variants of code invoke ub when accessing out-of-bounds array element. however, original code leave *pn @ value being passed f (= -1001) while rewritten code step ub-land after modifying *pn (to 0 ). would such difference coun...

so have string in activity2 string message = string.format( "current location \n longitude: %1$s \n latitude: %2$s", lat, lng); i want insert string text field in activity1. how can that? thank in advance. you can use intents, messages sent between activities. in intent can put sort of data, string, int, etc. in case, in activity2 , before going activity1 , store string message way : intent intent = new intent(activity2.this, activity1.class); intent.putextra("message", message); startactivity(intent); in activity1 , in oncreate() , can string message retrieving bundle (which contains messages sent calling activity) , call getstring() on : bundle bundle = getintent().getextras(); string message = bundle.getstring("message"); then can set text in textview : textview txtview = (textview) findviewbyid(r.id.your_resource_textview); txtview.settext(message); hope helps !
