when create new user database without rights, new user can still see schemas/tables etc. can't access them, still sees them. revoke these privileges, not know how. this how created user: create user wouter_test password 'wouter_test' nosuperuser nocreatedb nocreaterole nocreateuser inherit; based on post thought may have rights users have public schema , information public schema contains: https://dba.stackexchange.com/questions/98892/minimal-grants-for-readonly-single-table-access-on-postgresql based on wikisite: https://wiki.postgresql.org/wiki/shared_database_hosting used command revoke on schema public wouter_test; it did not work. following did not seem work either (to prevent user seeing , accessing database called klm ) revoke connect on database klm wouter_test; but still user, in pgadmin, can see databases, schemas , tables (including klm ). what doing wrong? you can revoke ... public forbid users use object, cannot keep user se...

as latest version of spark (2.1.0) lists unsupported major functionality of hive like: tables buckets: bucket hash partitioning within hive table partition. spark sql doesn’t support buckets yet. it means hive tables have bucketed column structure won't loaded dataframe processed properly. there workaround achieve such functionality via jdbc , temp tables , etc. main question how achieve full control using spark sql on tables materialized deltas ?

what want is, 2 different cache implementations (let's redis , ehcache) on 1 method. meaning @cacheable method should cache both redis , ehcache. is possible? option 1: stack caches. configure local cache in spring. wire in distributed cache via cacheloader/cachewriter. consistency needs evaluated. e.g. if update goes distributed cache, how invalidate local caches? not trivial. maybe easy , not needed data, maybe near impossible. option 2: go distributed cache provides called near cache . combination want yourself, combined in product. know hazelcast , infinispan offer near cache. however, mileage may vary regarding consistency , resilience. know hazelcast enhanced near cache, consistent. interesting use case , common problem. further thoughts , discussion highly appreciated.

i using sqlite-net library xamain , have question. call better or faster? var item = sqliteconnection.table<user>().firstordefault(e => e.id == myobject.id); or var item = sqliteconnection.table<user>().where(e => e.id == myobject.id).firstordefault(); either fine. they both run lazily - if source list has million items, tenth item matches both iterate 10 items source. performance should identical , difference totally insignificant. but i started getting "the wait operation timed out." using where(query).firstordefault() on large dataset. when changed firstordefault(query) stopped seeing it the difference when compare 2 approaches working out 1ms on 150,000 items (not 1ms each item, it's 1ms 150,000). based on 500 x 1,000 items query that's 0.003ms per day. it's not significant but prefer firstordefault(query)

i looking custom format of date , can't obtain it. i want obtain "1997-07-16t19:20:30.45+01:00" using following code : offsetdatetime o = offsetdatetime.now(); string l = o.format(datetimeformatter.iso_date_time); the result is: 2017-03-28t16:23:57.489+02:00 very close, need have hh:mm:ss.xx , , not hh:mm:ss.xxx . do know how customize offsetdatetime ? can't find examples. your answer almost correct. if take @ datetimeformatter javadoc , you'll see lowercase s corresponds seconds , , uppercase s , fraction of seconds : symbol meaning presentation examples ------ ------- ------------ ------- s second-of-minute number 55 s fraction-of-second fraction 978 so, in pattern, s , s inverted. correct pattern is: datetimeformatter formatter = datetimeformatter.ofpattern("yyyy-mm-dd't'hh:mm:ss.ssxxx"); offsetdatet...

i set aws instance in vpc private ip address -- no public ip address. going mongodb instance , accessed other servers within vpc. established successful vpn connection , can ssh using putty instance using private ip address - "10.0.0.95". far, good. noticed private ip address has private dns - "ip-10-0-0-95.internal". tried using private dns access instance through vpn got putty error "unable open connection ip-10-0-0-95.ec2.internal. host not exist". clearly, can use 10.0.0.95 ip address surprised private dns name did not work. how come? you should enable dns resolution vpc, or won't able resolve internal dns names. to use private hosted zones, must set following amazon vpc settings true: enablednshostnames enablednssupport steps enable dns resolution: open amazon vpc console @ https://console.aws.amazon.com/vpc/ . in navigation pane, choose vpc. select vpc list, choose actions , either edit dns resolution or edit d...

i'm using urlfetch google appengine, , add deadline parameter force deadline short (3 seconds), following : try: urlfetch.set_default_fetch_deadline(3) return urlfetch.fetch(url='http://www.example.com', method=urlfetch.get, deadline=3) except google.appengine.runtime.apiproxy_errors.deadlineexceedederror: pass except google.appengine.api.urlfetch_errors.deadlineexceedederror: pass return none but no matter what, thread goes on , on 60 seconds (the max execution time http request on appengine) , fail miserably on deadlineexception ("thread running after request."). is there way ensure upper query strictly stopped in 3 seconds? i can share code have running in 1 of production projects. use deadline of 0.5 seconds in example. last checked, it's still working: t_rpc = urlfetch.create_rpc(deadline=0.5) urlfetch.make_fetch_call(t_rpc, url) # , later... try: result = t_rpc.get_result() except: # handle errors... pass...

when want create table in pdf, can use following 2 ways : first 1 failed. method 1: float[] columnwidths = {20, 30, 50}; table table = new table(columnwidths); it's failed control columnwidths method 2: unitvalue[] unitvalue = new unitvalue[]{ unitvalue.createpercentvalue((float) 20), unitvalue.createpercentvalue((float) 30), unitvalue.createpercentvalue((float) 50)}; table table = new table(columnwidths); it's success! why happen? yes, there no way scale column widths in itext 7.0.2, vernon said. if want use directly 20, 30, , 50 points columns despite min widths shall use construction: table table = new table(new float[] {20, 30, 50}) // in points .setwidth(100) //100 pt .setfixedlayout(); if set fixed layout must set width well, required fixed layout.

i writing data chart com port during run time. such, chart dynamically updating gets increasingly bigger, scale changes making line smaller , smaller. wish stop deleting points off front of chart after it's big. if (chartmain.series.points.count() >= 120) { chartmain.series[0].points.removeat(0); } i need deletes first point after size scale remains same. however, not work in it's current form , unsure in how approach problem. can point me in right direction? thank in advance.

i've been using == operator in program compare strings far. however, ran bug, changed 1 of them .equals() instead, , fixed bug. is == bad? when should , should not used? what's difference? == tests reference equality (whether same object). .equals() tests value equality (whether logically "equal"). objects.equals() checks nulls before calling .equals() don't have (available of jdk7, available in guava ). consequently, if want test whether 2 strings have same value want use objects.equals() . // these 2 have same value new string("test").equals("test") // --> true // ... not same object new string("test") == "test" // --> false // ... neither these new string("test") == new string("test") // --> false // ... these because literals interned // compiler , refer same object "test" == "test" // --> true // ... should call objects.equals() o...

say have 2 nodes in scenekit scene. want 1 rotate around or orbit (like planet orbiting star), other node once in time interval. know can set animations so: let anim = cabasicanimation(keypath: "rotation") anim.fromvalue = nsvalue(scnvector4: scnvector4(x: 0, y: 1, z: 0, w: 0)) anim.tovalue = nsvalue(scnvector4: scnvector4(x: 0, y: 1, z: 0, w: float(2 * double.pi))) anim.duration = 60 anim.repeatcount = .infinity parentnode.addanimation(aim, forkey: "spin around") is there animation "orbiting", , way specify target node? the way using additional (helper) scnnode. you'll use fact adds own coordinate system , of child nodes move (helper) coordinate system. child nodes off-centre orbiting if view them world coordinate system. you add helpernode @ centre of fixedplanetnode (orbited planet), perhaps child, @ same position you add orbitingplanetnode child helpernode , offset on 1 of axes, e.g. 10 points on x axis you start he...
