i need execute loop while (x) y for n times, large number. while y, loop body, rather quick, test x takes 70% of runtime. i can calculate number of loop iterations n beforehand instead of using x condition, simple for-loop possible. for (i=1 n) y however, n might exceed maximum value integer can store on machine, not option. alternative, proposed use floating point variable f instead. n large, f cannot equal n. thus, calculate f largest floating point number smaller n. allows me run for (i=1 f) y while (x) y most of iterations not need test x everytime, last n-f do. the question is: how implement for-loop 1 f? increasing counter or decreasing f 1 in each step not work, numerical error grow large. current solution is: for (while f > maxint) (i=1 maxint) y f -= maxint while (x) y is there better way solve problem? what mean numerical error? floating point counting exact within precision. here maximum values representable integers using

consider blogging application allows offline mode in free version. , once user subscribes paid version - data being synced firebase. the question - since firebase has offline capabilities - can work (like parse) queries explicitly use local storage when querying data? (save/read). paid sync can feature flag because can tell skimming docs, offline capability seems "store offline until i'm online" scenarios thanks the firebase database online database, continues work while user offline. while user disconnected, firebase queues local writes operation in memory (and if call setpersistenceenabled(true) disk). way works means local-only performance worse local write queue grows. so unless have reasonable maximum local number of write operations, scenario may not work on firebase's offline architecture.

if have written own datasourcefactory , how can geo server recognize datasourcefactory ? know if register org.geotools.data.datastorefactoryspi automatically geo server recognizes our data source. don't know how register geo server . planning create java project (mvn). if implementing store can follow tutorial at: http://docs.geotools.org/stable/userguide/tutorial/datastore/index.html (geoserver expects find geotools data stores). in particular, answer specific question @ bottom of page, have register in meta-inf/services/org.geotools.data.datastorefactoryspi file: http://docs.geotools.org/stable/userguide/tutorial/datastore/source.html
