in application generate lot of subproblems exhaustively , solve them using "std::set" operations. need " insert " , " find " elements , " iterate " on sorted list. the problem each of millions of subproblems "std::set" implementation allocates new memory each time insert element in set makes whole application slow: { // allocate non-value node _nodeptr _pnode = this->_getal().allocate(1); // <- bottleneck of program is there stl-structure allows me to above operations in "o(log(n))" while not reallocating memory? using custom allocator seems way reduce amount of time spent building , releasing std::set<...> . below complete demo of simple allocator program profiling resulting times. #include <algorithm> #include <chrono> #include <cstdlib> #include <iostream> #include <iterator> #include <memory> #include <set> #include <vector> // --------

i have case class 2 string members. update second member later, first create instance string , none , later load data class , update second member value. how can it? define case class second member var : case class stuff(name: string, var value: option[string]) now can create instance of stuff , modify second value: val s = stuff("bashan", none) s.value = some("hello") however, making case classes mutable not idea. should prefer working immutable data structures. instead of creating mutable case class, make immutable, , use copy method create new instance modified values. example: // immutable stuff case class stuff(name: string, value: option[string]) val s1 = stuff("bashan", none) val s2 = s1.copy(value = some("hello")) // s2 now: stuff("bashan", some("hello"))

i have created test suites backbone.js application using jasmine.js framework. have 50 specs , backbone.js application has remote service calls. whenever running spec runner takes around 10 15 mins show results. same application working fast in different machine. using apache -tomcat server , eclipe ide. is there wrong application or else? how improve performance of jasmine-blanket specrunner.html? jasmine spec runner execute @ greater speed, if using memcached / memcache . jasmine spec runner speed depends on application performance. try use memcached or memcache application. i hope did not run memcached speed application. javascript frameworks uses more .js files develop mobile (web) applications. in case, if run memcached application, system execute @ speed. your alternate system might use (32 bit or 64 bit) memcached application. better check alternate system(mac).

in c++ if want partially specialize single method in template class have specialize whole class (as stated example in template specialization of single method templated class multiple template parameters ) this becomes tiresome in bigger template classes multiple template parameters, when each of them influences single function. n parameters need specialize class 2^n times! however, c++11 think there might more elegant solution, not sure how approach it. perhaps somehow enable_if ? ideas? in addition inheritance-based solution proposed torsten, use std::enable_if , default function template parameters enable/disable specializations of function. for example: template<typename t> struct comparer { template<typename u = t , typename std::enable_if<std::is_floating_point<u>::value>::type* = nullptr> bool operator()( u lhs , u rhs ) { return /* floating-point precision aware comparison */; } template<typename

i using git integrated domino designer(version 9.0.1). have associated .nsf project on-disk project. have synced on-disk project source control repository. seems way of doing things. on-disk project doesn't have java classes , packages had in .nsf project under "local" directory. how possibly sync these files , packages also? the "local" directory doesn't stored in on-disk project. used domino designer internally e.g. create java classes xpages. classes build , updated automatically during project build there no need save them in on-disk project source control reasons. store java classes , packages somewhere else in .nsf. classic way (compatible 8.5.x versions) put them design code element "java" folder "code/java" or "src" (java classes), "res" (resources/property files) , "webcontent/web-inf/bin" (jar files). since version 9 can put jar files design code element "jars".

is there elegant way convert dictionary (or sequence or generator) array. know can convert looping through sequence follows. var d = ["foo" : 1, "bar" : 2] var g: dictionarygenerator<string, int> = d.generate() var = array<(string, int)>() while let item = g.next() { += item } i hoping there similar python's easy conversion: >>> q = range(10) >>> = iter(q) >>> <listiterator object @ 0x1082b2090> >>> z = list(i) >>> z [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] >>> the + operator array accept sequence, can write var d = ["foo" : 1, "bar" : 2] var = [] + d i don't think similar possible generators though

my interest this: i'd set single homework repository share students. repository contains templates, specifications, , unit tests. students derive repository, complete homework, , push changes grading. this past year did using bitbucket. created public git repository containing files. created private forks. worked well. my problem this: whenever make changes files (i.e., fix bug in unit tests), students must actively sync original repo. many students not , not see updated files. know @ shell can execute git remote add skeleton git@bitbucket.org:prof/profrepo.git git pull skeleton master but i'd use in eclipse , in cs classes, technological intimidation issue , utility scripts not feasible. if tools set correctly, students still forget grab changes repository. is there way can integrate pulling original repo three-step pull-code-push workflow? git support this?

lately i've been reading lot on cqrs architecture. 1 of foremost points stated on why 1 should use cqrs scalability. now don't quite understand how can work. let's have typical cqrs application design. two datastores one command side one query side when command has been processed event send update second datastore it's stated having datastore querying , 1 handling commands make application more scalable. how can work if second datastore stores event data needs respond query requests , needs update iteself based on incoming events ? why not have 1 datastore commands stored , query side can re-use stored data fetching it's result data ? you might find interesting read old blog post greg young himself, explains cqrs is. cqrs not having 2 different stores, but, stated on greg's article: cqrs creation of 2 objects there one. separation occurs based upon whether methods command or query what describe here more event sourci

i've been trying import relatively large dataset neo4j...approximately 50 million nodes relationships. i first experimented cypher via py2neo -> work, becomes slow if need use create unique or merge. i'm looking @ other batch import methods, , i'm wondering if there recommendations of these approaches best general workflow , speed: the neo4j docs mention batch insertion facility appears java , part of neo4j distribution; there batch inserter michael hunger on @ github, not sure how similar or different 1 included in distribution; then there load2neo , i'm testing; and there load csv functionality part of neo v2's cypher, though not sure if convenience factor , if performance similar executing cypher queries in batches of, say, 40 000 via cypher transaction. i appreciate comments on functionality, workflow, , speed differences between these options. if can use latest version of neo4j recommended way use new load csv statement in cypher
