Java memory Management for JNI -

-

i have 2 questions :

  1. what if have jni call method , jni method leaks memory. once method completes jvm garbage collector able memory back. heard jvm not manage heap space used jni ? memory used jni part of memory used java process ?

  2. is absolutely necessary use jni achieve ipc ? other popular java techniques or there open source library achieve shared memory in java ?

  1. no: "the jni framework not provide automatic garbage collection non-jvm memory resources allocated code executing on native side" (wikipedia).
  2. no, java has sockets , indeed processbuilder. shared memory can achieved mappedbytebuffer.

i having super hard time compiling , using taglib 1.6.3 in qt project. i've tried can think of. taglib claims supported through cmake i'm not having luck. furthermore, i'm confused kinds of files need qt libs! i've built *.a files, *.lib, , *.dll. understand far... believe since i'm working in windows *.lib want. no matter do, end "undefined references" taglib functions try use when try compile qt project. have tried mingw32, msys, visual studio 2008, , cross-compiling windows on linux. turning nothing. what makes less sense me if compile same taglib source qt on mac (g++ think?) works fine! somewhere in windows compilation procedures have going wrong. have been smacking face on desk 30 (on , off) hours trying figure out. since qt uses mingw must compile taglib same compiler? if compile *.lib's visual studio not compatible? are *.a libraries usable in windows? (assuming mingw) i'm still trying handle on c++ stuff, after reading coun...

geospatial - MongoDB Bound Queries: How do I convert mile to radian? -

-
i have collection of stores geospacial index on location propery. what trying given user's latitude, latitude , search radius (mi), want return list of stores within parameters. i saw following example on mongodb documentation ( http://www.mongodb.org/display/docs/geospatial+indexing ), looks distance in radians. center = [50, 50] radius = 10 db.places.find({"loc" : {"$within" : {"$center" : [center, radius]}}}) so, formula convert miles radians? solution awesome people @ mongodb-user helped me find answer. basically, looking way limit distance. per, updated documentation, there 3rd parameter $near query: can use $near maximum distance db.places.find( { loc : { $near : [50,50] , $maxdistance : 5 } } ).limit(20) the value $maxdistance in radians; so, had take distance in miles , divide 69. thank you! as docs say: all distances use radians. allows multiply radius of earth (about 6371 km or 3959 miles) distance in choice ...
