showing applied configuration values in v2.0+ of riak there new command option: riak config effective which read tell current running values of riak. at time, can snapshot of applied configurations through command line. listing of of configs applied in node config changes applied on start of each node? in multiple locations in riak documentation there reference like: remember must stop , re-start each node when change storage backends or modify other configuration problem: however when made change setting (i've tested in both riak.conf , advanced.conf), see newest value when running: riak config effective ie: start node: riak start view current setting log level: riak config effective | grep log.console.level log.console.level = info change level debug (something output lot console.log) re-run: riak config effective | grep log.console.level , get: log.console.level = debug checking console log file debug: cat /var/l

i have 2 ways used convert characters representing 8bit byte values. in first 1 gives correct answer in second gives 0 had ba.size()-1 . question why have in second one? know /0 terminator. if im not wrong? there better way this? // simple test if can take bytes , them in decimal (0-255)format: qbytearray ba("down came glitches , burnt in ditches , slept after ate our dead..."); (int = 0; < ba.size(); ++i) qdebug() << "bytes are: "<< static_cast<quint8>(ba[i]); // simple second way it... int j = 0; while (j < ba.size()-1){ qdebug() << "bytes are: "<< static_cast<quint8>(ba[++j]); } the difference because of invalid use of increment operation. when use ++j has value 1 , never 0 index. last index bigger array size. right way is: qdebug() << "bytes are: "<< static_cast<quint8>(ba[j++]);

i want know if using fragments here... my application contains 6 activities. wanted add navigation drawer in process of converting each of these activities fragments. when select option drawer, appropriate fragment appear. fragments "stand alone" meaning each fragment self contained , not interacting other fragments, example calendar displays date. this same on every device, whether tablet or phone. every tutorial have seen fragments has multiple fragments interacting 1 another. mine not. question is, design perspective, ok use fragments in manner? or should use activities instead? thank you. if drawer, proper design use fragments. should using fragments whenever it's possible, makes code easier maintain , control. communication between fragments easier communicating between activities. in addition, activities expensive operate. activities created not implicitly destroy previous activities.

i'm trying learn bit using namespace, created 2 items using namespace. in future when implemented there x-number of items created using namespace. how can count number of "cilinders" there exist? public class form1 ' test using namespace private sub button4_click(sender object, e eventargs) handles button4.click ' create cilinder 1 dim cilinder_1 new body_namespace.body_cilinder cilinder_1.index = 1 debug.print(cilinder_1.index) ' create cilinder 2 dim cilinder_2 new body_namespace.body_cilinder cilinder_2.index = 2 debug.print(cilinder_2.index) end sub end class namespace body_namespace class body_cilinder private _index integer public property index() integer index = _index end set(byval value integer) _index = value end set end property end class end namespa

i have downloaded r# 9.1 in order integrate stylecop it. passed when installing both r# , extension stylecop. however, when go solution folder (in visual studio 2015) , right-click on 1 of projects , click on "run stylecop" displays error: initially installed r# 9.2 , result same, decided go 9.1 version. reinstalled r# , stylecop both once , multiple times r#'s extension integrating stylecop. my current set r# , stylecop is: resharper 10.0.1 stylecop jetbrains 4.8 which gives in r# options: this gives me r# validation of rules. however, doesn't give me right click run functionality. so had click around , found stylecop doesn't have install vs 2015, installed visual stylecop , have recreated issue. if using visual stylecop may worth while adding issue on github. personally, don't use right click functionality, instead warnings build via stylecop.msbuild nuget package each project want monitor: once have no errors, us

my co-worker found morning compiling project cobertura enabled changes sonar results on same project. on particular project ran build sonar:sonar , ran again cobertura:cobertura sonar:sonar . the sonar results in comparison showing without cobertura have 7/78/153/24/0 violations of 5 severities, cobertura changes 7/81/94/24/0 , , in particular finds 3 new critical violations , 15 new major violations aren't found without cobertura. one of biggest changes without cobertura there 60 violations of rule against empty methods (many of them constructors) , cobertura 3 of reported. if cobertura prevented violations being found run 2 independently, since violations found cobertura enabled seems have 2 separate sonar analyses. is known interaction? there workaround other doing cobertura , sonar in separate builds? , using both sets of results best data? based on comment made let me explain seems happening: using findbugs via sonarqube (rules mentioning findbugs rule

how compute basis of nullspace of matrix eigen library? i tried find explicit function name compute null basis , also, workaround, find method computing rref of matrix (as we're able null basis rref). but couldn't find relevant functions names. i think there's must solution this, know not eigen library , eigen's code difficult me understand. please suggest me solution problem. you can basis of null space using eigen::fullpivlu::kernel() method: fullpivlu<matrixxd> lu(a); matrixxd a_null_space = lu.kernel();
