can use this? select /*+ mapjoin(t2)*//*+ streamtable(t1)*/ t1.c1. t2.c1 t1 left outer join t2 on t1.c1 = t2.c1; and confuse "streamtable" on different join keys. for example: t3 biggest table,and t2 secondary big table,t1 smallest table. select /*+ streamtable(t2)*/ t1.c3, t2.c2, t3.c3 t2 left outer join t1 on t2.c1=t1.c1 left outer join t3 on t2.c2=t3.c2; so if when t2 join t1 it's ok.but when t2 join t3,if t2 if still treated big table? how can handle situation? you can achieve following: select /*+ mapjoin(t2), streamtable(t1)*/ t1.c1. t2.c1 t1 left outer join t2 on t1.c1 = t2.c1; there non-trivial number of cbo-related defects might still run into, involving windowing functions , columnar formats in experience. therefore useful know how apply hints.

i have issue ionic app on iphone. ionic writes index.html: <iframe src="gap://ready" style="display:none;">...</iframe> the console output of app loops error 40 times per second: refused load gap://ready because appears in neither child-src directive nor default-src directive of content security policy. i guess everytime dirtycheck of angular working, error thrown. iframe comming , how can rid of iframe , error? solution, add gap: following meta tag in index.html : <meta http-equiv="content-security-policy" content="default-src * data: cdvfile: gap:; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'"/>

i want show information on page regarding multiple queries, each of them representing project status. that, made while loop, adds information array. the problem that, show 1 of statuses available, first one. here code: $exec = mysql_query($queryontime) or trigger_error(mysql_error()); $exec1 = mysql_query($querydelayed) or trigger_error(mysql_error()); $exec2 = mysql_query($querypending) or trigger_error(mysql_error()); $array_dados = array(); // chart data while($info = mysql_fetch_array($exec)||$info1 = mysql_fetch_array($exec1)||$info2 = mysql_fetch_array($exec2)){ $array_dados[] = $info; $array_dados[] = $info1; $array_dados[] = $info2; } return $array_dados; so can see, have 3 queries, , try adding of them array, yet 1 of $info shows up. why that? edit: i removed or , separated fetch arrays, yet still shows "pending" one. here's how looks right now: $exec = mysql_query($querypending) or trigger_err

during distributed training want sync after each epoch, calculations on chief worker , proceed or stop training depending on these calculations. need barrier so. i don't see similar in documentation, implemented solution based on queues (similar how gradients stored , applied in distributed training): def build_barrier(tasks, task_index, barrier_name): queues = [] i, task in enumerate(tasks): tf.device('%s/cpu:0' % task): tf.name_scope(barrier_name): queues.append( tf.fifoqueue( len(tasks), (tf.float32), shapes=(()), name=str(i), shared_name=str(i))) tf.control_dependencies([queue.enqueue(1.) queue in queues]): return queues[task_index].dequeue_many(len(tasks)) the idea create queue per worker.

so need understanding happens when piping requests , if there difference between node 0.10.x , 4.5.x i have this: function(req, res, next){ if(req.method === 'put'){ var putoptions = { uri: config.url + req.url, headers: { token: req.session.token }, jason: req.body }; var r = request.put(putoptions, callback); return req.pipe(r).pipe(res); } } now works fine in node 0.10.x, in 4.5.x "write after end" error, unless remove req.pipe -part , r.pipe(res) , works fine in 4.5.x. now in understanding difference between these two, happens, , why behaves differently in different node versions. thanks help! ---update--- ok when tried req.pipe(r, {end: false}).pipe(res) worked in 4.5.x, i'm no longer getting "write after end"-error ... i'm still bit confused why there difference.. docs regarding pipes doesn't seem have changed since 0.10

i read article python retains number objects better performance. example: x = 3 y = 3 print(id(x)) print(id(y)) gives out same values, means x , y referencing same object. article suggested retained number objects approximately in range 1~100. so tested following code getting exact range: for in range(-1000,1000): x = int(str(i)) y = int(str(i)) if str(id(x)) == str(id(y)): print(i) and result quite weird: prints out -5~256. i'm wondering how these 2 magic numbers came , why they're being used. also, these 2 values change in different environment? thanks! 256 power of 2 , small enough people using numbers range. -5 less sure about, perhaps special values? related: what's integer cache inside python? also word of wisdom thread: this implementation detail, don't ever rely on happening or not happening

i change default font bootstrap sass , found this: //== typography // //## font, line-height, , color body text, headings, , more. $font-family-sans-serif: "helvetica neue", helvetica, arial, sans-serif !default; $font-family-serif: georgia, "times new roman", times, serif !default; what's difference between sans-serif , serif in context? because if inspect page, fonts helvetica neue. how serif/georgia utilised if i'm seeing helvetica neue being used? those options change base style font if want serif or sans-serif. this: create 3 base styles: $font-family-sans-serif: "helvetica neue", helvetica, arial, sans-serif !default; $font-family-serif: georgia, "times new roman", times, serif !default; $font-family-monospace: menlo, monaco, consolas, "courier new", monospace !default; then set sans-serif on base var: $font-family-base: $font-family-sans-serif !default;

docker plugin found (spotify/docker-maven-plugin) use native docker application, far understand docker rest api client "redirects" commands docker daemon process. it's true in case if use docker on windows machine , docker daemon works on linux in virtual box. so, docker-maven-plugin exist doesn't require native docker application , "talking" docker daemon without intermediaries? it doesn't require native docker application, knowing docker daemon is. docker-maven-plugin per documentation : by default plugin try connect docker on localhost:2375. set docker_host environment variable connect elsewhere. docker_host=tcp://<host>:2375 this how client knows docker daemon is. docker-maven-plugin respects (and other) docker environment variables know docker resides, whether native, in vm running on hypervisor virtualbox locally, or on remote server. docker machine if you're using docker machine, these environment var

in simulator works well, in smartphone when scrolling down in infinitecontainer can see black flickering (probably related getting data server) can somehow prevent behaviour? thanks jb make sure code doesn't block fetch method long. needs fast. if need networking construct components make sure use addtoqueueandwait , process components correctly on event dispatch thread.

i have jhtmlarea textarea on form textarea id="txtdigital" name="txtdigital" class="form-control" style="background-color:white; resize: vertical !important; " rows="20" placeholder="details" runat="server"></textarea> which being set in javascript with: $(document).ready(function () { $(function () { $("#<%=this.txtdigital.clientid%>").htmlarea({ toolbar: [ ["bold", "italic", "underline", "strikethrough"], ["increasefontsize", "decreasefontsize", "forecolor"], ["orderedlist", "unorderedlist", "superscript", "subscript"], ["indent", "outdent", "justifyleft", "justifycenter", "justifyright"] ] });

i have table 3000 entries. randomly choosing 25 of shifted table. once done, want ids (which assigned auto_increment , primary key) in original table in sequence, perform next iteration. how should it? we cannot change auto_increment value value other current max value.auto_increment counter keeps on incrementing value used column defined. the other way change value above current max value manually alter value of auto_increment counter max(value) +1. so guess here have order records in ascending existing id after deleting 25 records , manually set id value of each record according incrementing variable , in end set auto_increment count value value of variable in end +1. sample : alter table t set auto_increment=some_value; though advised leave auto_increment alone , avoid if it's done sake of making ids great , there no other probable reason.

what best way design custom buttons , using them within xcode. want them not random buttons. should button apple themselves. you can use uibutton , can set easily: background color, background image font type, font color round corner dimensions dynamics right constraints what kind of button want make? see this link basic tutorial meantime.

i authorize users based on few roles. visitors should able reach method show. wrote in appcontroller: public function beforefilter(event $event) { $this->auth->allow(['show']); } it works. in initialize() method of appcontroller i've got also: $this->loadcomponent('auth', [ 'authorize' => 'controller' ]); i allow logged users role "user" reach "index", , "add" methods, wrote in appcontroller: public function isauthorized($user) { if (isset($user['role']) && $user['role'] === 'admin') { return true; } if (isset($user['role']) && $user['role'] === 'user') { $this->auth->allow(['index', 'logout', 'add']); } return false; } admin can reach methods expected. user logged role "user" can't reach "index" or "add" method. how can fix this? instead of using

we have deployed 2 ears both same package file structure. possible wildfly log info 2 separate log files whereby each ear has own logging information? if so, how configure in config file? yes possible log information on separate files in wildlfy. need define multiple logging profiles on wildfly configuration file. create new logger profile either using jboss cli or directly updating standalone.xml file. open standalone.xml file , update following section, <subsystem xmlns="urn:jboss:domain:logging:3.0"> and update section like, <logging-profiles> <logging-profile name="accounts-app-profile"> <console-handler name="console"> <level name="info"/> <formatter> <named-formatter name="color-pattern"/> </formatter> </console-handler> <periodic-rotating-file-handler name="file&

i'm looking best method in sass iterate class's order go 1 every 4 item. came following gets result wanted, comes lot of perhaps unnecessary markup. @for $i 1 through 3 { &:nth-child(#{$i}) { order: 3; background: green; } } @for $i 4 through 6 { &:nth-child(#{$i}) { order: 1; background: blue; } } @for $i 7 through 9 { &:nth-child(#{$i}) { order: 2; background: red; } } full example of code working on codepen is there better way missing? this you're asking single loop , math. there's more efficient way, come with: .box { @for $i 0 through 9 { $c : $i + 1; &:nth-child(#{$c}) { order: (($i - $i % 3) / 3) + 1; } } } outputs: .box:nth-child(1) { order: 1; } .box:nth-child(2) { order: 1; } .box:nth-child(3) { order: 1; } .box:nth-child(4) { order: 2; } .box:nth-child(5) { order: 2; } .box:nth-child(6) { order: 2; } .box:nth-child(7)
