what doing : from java code retrieving notes database , indexing documents of database using full text indexing using solrj client , saving indexed data of particular documents on full text server. suppose when same database comes again indexing, considered 1 of documents database deleted indexed on full text server, but document deleted notes database don't want keep (means want delete) indexed data on full text server of deleted document. so how know document deleted what thinking is , store document's id , db name while indexing, have record of indexed documents, can identify documents deleted particular database. any other efficient way? thank reading question. the document universal id of document unique identifier @ least complete database. you can document.getuniversalid() in java by design every unique id unique worldwide, designer can go around (unids writable) , replicas of course have documents same unique id. combine unid fil

through amount of debugging (i not wish repeat) i've found circumstance can arrived @ if 1 of objects given comparator breaks interface's contract (namely comparator compare(a, a) returns non-zero value). what kind of exception should throw? i thought take inspiration treemap, takes comparator, acts bizarrely (not throwing exception) if give nonsense comparator. the common way use java.lang.illegalargumentexception : throw new illegalargumentexception("one of objects given breaks comparators interface contract "); you can take @ documentation : thrown indicate method has been passed illegal or inappropriate argument.

let's have type declaration: data mytype = n double | c char | placeholder i want able treat mytype double whenever it's possible, num, real, fractional functions resulting in n (normal result) arguments wrapped in n constructor, , placeholder other arguments > (n 5.0) + (n 6.0) n 11.0 > (n 5.0) + (c 'a') placeholder is there way other defining class instance of classes in manner similar to: instance num mytype (+) (n d1) (n d2) = n (d1+d2) (+) _ _ = placeholder ... (which seems counter-productive)? there no generic deriving available in standard haskell : currently, deriving available defined compiler specific prelude typeclasses: read , show , eq , ord , enum , , bounded . the glasgow haskell compiler (ghc) apparently has extensions support generic deriving . however, don't know if save work try , use them: how many typeclasses need derive num instance from? and, sure can define automatic scheme deriving num want?

seems strange, cannot find easy way find local timezone using pandas/pytz in python. i can do: >>> pd.timestamp('now', tz='utc').isoformat() out[47]: '2016-01-28t09:36:35.604000+00:00' >>> pd.timestamp('now').isoformat() out[48]: '2016-01-28t10:36:41.830000' >>> pd.timestamp('now').tz_localize('utc') - pd.timestamp('now', tz='utc') out[49]: timedelta('0 days 01:00:00') which give me timezone, not best way it... there command in pytz or pandas system time zone? (preferably in python 2.7 ) i don't think possible using pytz or pandas , can install python-dateutil or tzlocal : from dateutil.tz import tzlocal datetime.now(tzlocal()) or from tzlocal import get_localzone local_tz = get_localzone()

in app update application badge after events using code works: [[uiapplication sharedapplication] schedulelocalnotification:localnotification]; however [uiapplication sharedapplication] cannot called watchkit or widget. there way widget update application badge other way? i tried using background fetch this. badge gets updated when explicitly "simulate background fetch" xcode. on actual device background fetch never gets called? idea command call background fetch? - (void)application:(uiapplication *)application performfetchwithcompletionhandler:(void (^)(uibackgroundfetchresult))completionhandler { // background fetch [[globalnotifications sharedinstance] setapplicationbadge]; completionhandler(uibackgroundfetchresultnewdata); } thanks insight on this. you correct schedulelocalnotification can called ios main app. watch app, if using watchos 2 can tell ios app schedule notification in background using watchconnectivity. recommend using wcse
