i having brain cramp. below toy dataset: df <- data.frame( id = 1:6, v1 = c("a", "a", "c", na, "g", "h"), v2 = c("z", "y", "a", na, "a", "g"), stringsasfactors=f) i have specific value want find across set of defined columns , want identify position located in. fields searching characters , trick value looking might not exist. in addition, null strings present in dataset. assuming knew how this, variable position indicates values returned. > df id v1 v2 position 1 1 z 1 2 2 y 1 3 3 c 2 4 4 <na> <na> 99 5 5 g 2 6 6 h g 99 the general rule want find position of value "a", , if not located or if v1 missing, want 99 returned. in instance, searching across v1 , v2, in reality, have 10 different variables. worth noting value search...

so writing app android push data on amazon s3 storage later read. using amazons sdk make calls requires me store public , private keys within app. there way secure them couldn't extracted reverse engineering? possible since making direct calls device? or option run proxy server (on ec2) , pass data through it? thanks help! step 1. use https step 2. aes encrypt keys in application other that, there's not can do, other using proxy server (option mentioned)

i've got input array in format: [[timestamp, jobid, time completion],[..]] the data sql db, grouped both timestamp, , jobid, array looks like: [ [1, 30, 400], [1, 31, 200], [2, 29, 300], .. ] i create new array 1 column every jobid, instead of 1 row every job id, is, single row per timestamp. so, wrote code iterated through above array, , populated new array, simple enough, except, result array isn't fixed width, is, result looks like: [ [1, 400, 200], [2, 300] .. ] which makes impossible me values [1] job id 30, can't have meaningful header row. is, data in format: timestamp, jobid29, jobid30, jobid31 [ [1, 0, 400, 200], [2, 300, 0, 0], .. ] i can't output map, unfortunately. how can achieve this? know i'll haveto go through input once distinct jobids, , guess i'd map each jobid position, etc, i'm wondering if best way? thank you. my solution uses 2 arrays , 2 maps plenty of possibilities optim...

i using long / integer data types in application, build generic datatypes. fear using these wrapper objects instead of primitive data types may harmful performance since each time needs create objects expensive operation. seems have no other choice(when have use primtives generics) rather using them. however, still great if can suggest if there make better. or way if avoid ?? also may downsides of ? suggestions welcomed! repeat after me. "creating object in java not expensive operation" . you prematurely optimizing application. better approach implement in natural way using integer , long , profile determine bottlenecks are. if profiler tells use of integer , long performance issue, then @ ways cure this. if determine integer , long issue, here things do: look class library implements "collections" of primitive types; e.g. trove. beware apis of such collection types won't compatible java.util.collection , descendants. us...

i have used jquery calendar, , have used create event details, want export same event details google calendar,ical , microsoft outlook, depending upon user requirements.but want procvide 3 features. there tools available or have dirty hands code whole thing myself. fyi:i have used servlets , mysql @ end , jquery along html5 @ front end. since using java on server side, can use ical4j library creating icalender. basically, need ical completing requirement. google, microsoft, apple , many others mozilla sunbird support icalender can use 1 format, rather going different formats.

i trying apply timing decorator described here method within class instead of standalone method. how should done? i getting error: typeerror: unbound method wrapper() must called someclass instance first argument (got float instance instead) edit thanks comment, think know problem is. doesn't work: class a: @timings @classmethod def a(cls, x): print(x) a.a(2) for reason said. typeerror: unbound method wrapper() must called instance first argument (got int instance instead) but does: class a: @classmethod @timings def a(cls, x): print(x) a.a(2) so order matters. think what's going on here it's fooling way python handles bound methods: when python looks @ member a, has make decision: make bound method make class method do nothing (leave is) if gets regular function, (1), , @timings produces regular function. does solve problem?

i've been putting page today , thought i'd implement striped background using css3. seemed fine in browsers except firefox.

possible duplicate: is there advantage of being case-sensitive programming language? my first programming experiences basic family (msx basix, q-basic, vb). these not case-sensitive. now, might because of these first experiences, i've never grasped benefit of language being case sensitive. on contrary, think source of unneeded overhead , bugs, , still annoys me when use e.g. java or c. now, read on clojure (a lisp-dialect) , noticed - surprise - 1 of differences lisp case-sensitivity . so: benefit (to programmer) of having case-sensitive language? the things can think of are: double number of symbols visual feedback , easier reading complex variables using techniques camelcase, e.g. hopcount however, first argument doesn't hold because of being major source bugs (bad practice use hopcount , hopcount in 1 method). the second argument doesn't hold either, decent ide can provide in other way. example vba ide, has approach: langauge case-insensit...
