i have postgresql database use production server. want set hadoop/spark cluster run mapreduce jobs. in order need load data postgres database hdfs. naive approach have batch job once day dumps contents of database (120gb) hdfs. wasteful , costly. since data won't change 1 day next, theoretically cheaper , more efficient send diffs every day. possible? i've read little sqoop, , seems provide functionality want, requires making changes database , application. there way doesn't require making changes database? apache sqoop can connect postgresql database. sqoop provides incremental import mode can used retrieve rows newer previously-imported set of rows, i.e, can table updates happened between previous run , current run. no changes required database. using sqoop postgresql connector can connect sqoop database , incremental imports without database changes.

i creating image object want set url of image dynamically. image img = new image(); if(vehicletype.equals("car")) img.seturl(images/car.png); else img.seturl(""); here, don't know if car.png exists in images folder in classpath. how can check existence? want set default vehicle image object if car.png not on classpath. thanks you can't check if image on class path client side. what can add errorhandler image adderrorhandler() method can detect if browser can't load image (because doesn't exist on server side example). image img = new image(); img.seturl("set url"); img.adderrorhandler(new errorhandler() { @override public void onerror(errorevent e){ // failed load image } }); note: there image.addloadhandler() method can use detect when image loaded. another way create method @ server side published in service checks if image availabe, , call method client code. a side note if...

i have following configuration in application. writing file ftp folder , reading ftp location. i want take file ftp location , save in directory decided dynamically. done using 2 chained channel adapters. ftp nbound channel adapter picks file, puts in local directory , file inbound channel adapter picks file , puts in final destination. need filter old files process. ftp inbound channel adapter custom filter gave me ftpfile object in filtering method. object gives last modified date rather date file put in filter. due limitation had use file inbound channel adapter well. since not know how generate source directory dynamically, using plain java code copy required file local-directory ftp outbound channel picks , puts on ftp location. this configuration: <bean id="filenamegenerator" class="com.polling.util.filenamegenerator"/> <int-file:inbound-channel-adapter id="filesin" directory="file:${paths.root}" channel=...

int main(){ int n; scanf("%d",&n); int a[n]; } in above space array a[] , allocated ? in stack or heap ? if compiler compiles that, it's going on stack. in standard parlance, if care apply construct that's not standard-conforming, has automatic storage duration, meaning don't have clean , become invalid @ end of scope. what have there vla (variable length array), construct c allows have arrays dimensions known @ runtime. usually, way work similar "function" alloca , decreases stack pointer amount known @ runtime , "returns" pointer it. put "function" in quotes because doing requires low-level hackery that's not provided normal function scope semantics. vlas don't exist in c++, you're using compiler extension, , precise semantics of vlas in extension depend on compiler. since gcc, i'll leave link the relevant part of documentation .

i'm not getting concept web api , session. i've created asp.net web api project , integrated angularjs in it.every time i'm gonna call web api. i have read articles state not use session in web api. understand web api stateless approach. agree. stil there way use session. first question: if, after login, want show user name on every page should web api approach???? second question: don't use session in webapi. other way/approach store client information safely. if use html5 local storage, can editable. if cookie used, can deleted. what , how should user till application in running mode? this semantics clouds discussion. people confuse session object statelessness. , say: 'don't use session because isn't stateless!'. however mean should strive have restful calls idempotent, meaning don't change behavior depending on whatever in background. session, or runtime-cache, or whatever use cache data, has no effect on stateless d...

how can tune performance (by perhaps changing parameters) make https faster in oracleas? thank you please refer documentation tuning standards: https://docs.oracle.com/cd/e23943_01/core.1111/e10108/http.htm#asper99079 here relevant pieces effect ssl tuning in experience can make difference: section 5.4.1.1: sslsessioncachetimeout directive in ssl.conf determines how long server keeps saved ssl session (the default 300 seconds). session state discarded if not used after specified time period, , subsequent ssl request must establish new ssl session , begin handshake again. section 5.4.1.3: if large volumes of data being protected through ssl, pay close attention cipher suite being used. sslciphersuite directive specified in ssl.conf controls cipher suite. if lower levels of security acceptable, use less-secure protocol using smaller key size (this may improve performance significantly). finally, test application using each available cipher suite specified security...

it used case matlab better @ creating interactive plots. is, plots 1 able use mouse interactively change aspects of plot, height , width, x , y limits, position of legend, ... akin of having plot creation , and svg editor in same place. what best way achieve same goal in open source r? alternative being, produce plot r, save pdf or svg, open file open source svg editor inkscape, , edit layout of plot second step. is there r package in place? there few r packages allow jump either tcl or opengl world of interactive graphics (and believe x11 tools well). further, there package, name sadly escapes me @ moment, runs "on top of" base plotting tools , lets of interactive rescaling work. however, suggest spend little time learning ggplot , change approach graphics generation. unless intent manipulate graph in realtime for, e.g., presentation, it's more efficient edit grob object , replot until image want. remember, first rule of efficient programming ...

i'm new developing excuse me if or ask doesn't make sense @ all. working on project in want play audio files mp3. allready made play pause button. got work music plays , when press on button "pause" text changes "play". want make playpause button image instead of plain text.
