i'm trying discover few services using nerve . while came across timeout configuration specified in nerve docs . timeout: (optional) maximum time check can take; defaults 100ms however when @ examples provided, timeout mentioned "0.2". does mean timeout these examples " 0.2ms "? valid configuration timeout? or 0.2 considered 2 sec ? i went through code nerve , looks timeout configuration provided in nerve json read value , directly pass http client read_timeout without additional processing. as per ruby documentation, value in seconds. so 0.2 means 200ms. i'm assuming nerve docs not updated or has mistake w.r.t documentation. read_timeout[r] number of seconds wait 1 block read (via 1 read(2) call). number may used, including floats fractional seconds. if http object cannot read data in many seconds, raises net::readtimeout exception. default value 60 seconds.

i have been googling haven't yet found answer question. have application , have client library connecting me database (in case, it's ravendb). i ravendb client messages go separate file (meaning, messages instances of classes of raven.client.xyz should logged raven-client.log file - actions client library performs, e.g. connecting server, waiting response, getting/updating documents, querying index, etc. , not code interacting client library ). how can achieve that? tried separate appender, ravendb logs appear in application logger too. i'm using xml configuration , log4net version 1.2.10 actually, checked , solution works: <log4net> <appender name="consoleappender" type="log4net.appender.consoleappender"> <layout type="log4net.layout.patternlayout"> <conversionpattern value="%utcdate [%thread] %-3level %logger - %message%newline" /> </layout> </append

i have dataframe containing 20k rows. i want delete 186 rows randomly in dataset. to understand context - testing classification model on missing data, , each row has unix timestamp. 186 rows corresponds 3 seconds (there 62 rows of data per second.) my aim is, when data streaming, data missing number of seconds. extracting features time window, want see how missing data effects model performance. i think best approach convert rdd , use filter function, this, , put logic inside filter function. dataframe.rdd.zipwithindex().filter(lambda x: ) but stuck logic - how implement this? (using pyspark) try this: import random startval = random.randint(0,dataframe.count() - 62) dataframe.rdd.zipwithindex()\ .filter(lambda x: not x[<<index>>] in range(startval, startval+62)) this should work!

is there advantage using angular 2 button/tabs/any other html component on creating component in plain html/css globally reusable code? will overhead using angular 2 button component on normal buttons? the advantage don't need build ;-). the disadvantage might contain more code (ts, html, css) , several imports of components built of might necessary current use case because built in generic way can used in many use cases. another disadvantage might limited how can customize while limited browser allows if build yourself. if care additional code, html, css i'm pretty sure it's case of premature optimization without knowing more details concrete requirements it's hard tell.

consider table example using these table wanted print table these adding rowspan item id 1002. here php code $temp_val = ''; $counter = 1; $sql_sel = mysqli_query($con,"select * item_table"); while($res_sel = mysqli_fetch_array($sql_sel)){ if($temp_val == $res_sel['item_id']){ $counter++; echo "<tr></tr>"; } else{ echo "<tr><td rowspan='".$counter."'>".$res_sel['item_id']."</td></tr>"; } $temp_val = $res_sel['item_id']; } echo "</table>"; it's not correct, it's adding rowspan item id 1003 you should switch code inside else , if statement

this question has answer here: why void function return value? 5 answers please me understand going on here: main.java: int[] myarray = new int[125]; // setup array here, code omitted. int minimum = processarray.min(myarray ); // array values print if have been sorted... for(int i=0; i<myarray.length;i++) { system.out.println(myarray[i]); } processarray.java import java.util.arrays; public class processarray { public static int min(int[] anarray){ arrays.sort(anarray); return anarray[0]; } } after finding minimum value of array, array print in sorted order. why array re-arranged in sorted order? when pass array function reference myarray not clone/copy your minimum function sorted array, sorted after call you can clone array manually keep original array int minimum = processarray.min(myarray.clone()); or use arr

consider following code: string commandf = "ls /etc | grep release"; try { // execute command , wait complete process child = runtime.getruntime().exec(commandf); child.waitfor(); // print first 16 bytes of output inputstream = child.getinputstream(); byte[] b = new byte[16]; i.read(b, 0, b.length); system.out.println(new string(b)); } catch (ioexception e) { e.printstacktrace(); system.exit(-1); } the program's output is: /etc: adduser.co when run shell, of course, works expected: poundifdef@parker:~/rabbit_test$ ls /etc | grep release lsb-release the internets tell me that, due fact pipe behavior isn't cross-platform, brilliant minds work in java factory producing java can't guarantee pipes work. how can this? i not going of parsing using java constructs rather grep , sed , because if want change language, i'll forced re-write parsing code in language, totally no-go. how can make java piping

i'm trying akka.net cluster tools, in order use singleton behavior , seems work perfectly, when current singleton node "host" leaves cluster in gracefully way. if shutdown host node, handover not occur. background i'm building system composed 4 nodes (initially). 1 of nodes "workers coordinator" , responsible monitor data database and, when necessary, submit jobs other workers. thinking subscribe cluster events , use role leader changing event make actor (on leader node) become coordinator, think cluster singleton better choice in case. working sample (but if gracefully leave cluster) private void start() { console.title = "worker"; var section = (akkaconfigurationsection)configurationmanager.getsection("akka"); var config = section.akkaconfig; // create new actor system (a container actors) var system = actorsystem.create("singletonactorsystem", config); var cluster = cluster.get(system);
