i'm using solr indexing products , organising them several categories. each document has taxon_names multi value field, categories stored human readable strings product. now want fetch categories solr , display them clickable links user, without hitting database again . @ index time, permalinks every category mysql database, stored multi value field taxon_permalinks . generating links products, need human readable format of category , permalink (otherwise have such ugly urls in browser, when using plain human readable name of category, e.g. %20 space). when facet search http://localhost:8982/solr/default/select?q=*%3a*&rows=0&wt=xml&facet=true&facet.field=taxon_names , list of human readable taxons counts. based on list, want create links, don't have hit database again. so, possible retrieve matching permalinks solr different categories? example, xml this: <response> <lst name="responseheader"> <int name="status"

i have string: a = "{user_id:34dd833,category:secondary,items:camera,type:sg_ser}" i need convert python dictionary, that: a = {"user_id":"34dd833", "category": "secondary", "items": "camera", "type": "sg_ser"} on top of that, there 2 more issues: 1: "items" key supposed have multiple values, like: a = {"user_id":34dd833, "category": "secondary", "items": "camera,vcr,dvd", "type": "sg_ser"} which apparently comes form of string as: a = "{user_id:34dd833,category:secondary,items:camera,vcr,dvd,type:sg_ser}" so, generalizing based on comma separation becomes useless. 2: order of string can random well. so, string can well: a = "{category:secondary,type:sg_ser,user_id:34dd833,items:camera,vcr,dvd}" which makes process of assuming thins order false one. what in such situati

first off, i'm doing project school , not allowed use external libraries , hence cannot use gmp. problem is, have function requires "tough" calculations. ie, m^e mod n here's code #include <iostream> #include <math.h> using namespace std; int main() { int e = 17, n = 3233, m = 65; long double p, mod; p = pow(m, e); // gives 6.59974e+30 correct mod = fmodl(p, n); cout<<mod; // gives 887, when correct answer 2790 return 0; } as can see fmod (fmodl) function not return correct value there workaround ? again, without using external libraries. you can write own modulo power function. int modpow(int a,int b,int mod) { int product,pseq; product=1; pseq=a%mod; while(b>0) { if(b&1) product=(product*pseq)%mod; pseq=(pseq*pseq)%mod; b>>=1 } return product; } refer http://en.wikipedia.org/wiki/modular_exponentiation explanation

there many ways initialize object, 1 of calling constructor of centain user-defined type. here examples. hello my_hello = hello(3); hello my_hello(3); as know, constructor doesn't return anything. however, above, seems return initialized object. furthermore, assignment operator makes more suspicious because means copys right-hand object left-hand object. am guessing wrong? please explain it? the declaration hello my_hello = hello(3); creates 2 objects. first temporary object hello(3) , , temporary object copied through copy-constructor my_hello followed destruction of temporary object. however, further muddle water, copying , destruction of temporary object may not happen due copy elision , common compiler optimization.

i working on simple java ee application. i have class this: import javax.annotation.postconstruct; import javax.ejb.stateless; import javax.persistence.entitymanager; import javax.persistence.entitymanagerfactory; import javax.persistence.persistence; @stateless public class blogentrydao { entitymanager em; @postconstruct public void initialize(){ entitymanagerfactory emf = persistence.createentitymanagerfactory("persistence"); em = emf.createentitymanager(); } public void addnewentry(){ blogentry blogentry = new blogentry(); blogentry.settitle("test"); blogentry.setcontent("asdfasfas"); em.persist(blogentry); } } so managed bean calls method. until here no problems. since initialize method not called, getting npe in em.persist . why initialize method not being called? running on glassfish server. regards. the java ee bean annotations such @postconstruct

i'm trying write code xna have own drawing modules can use cache/draw static vertices/indices. here's class , line in question giving me trouble line 51. _vertexbuffer.setdata(_vertices.toarray()); it has error: the type 't' must non-nullable value type in order use parameter 't' it doesn't seem setdata expects array of vertices matches vertexdeclaration used in vertexbuffers constructor, whilst definition of list/class says can type. is there anyway specify <t> vertices? they called generic type constraints . whatever vertexbuffer type is, has on method: void setdata<t>(...) t : struct this causing error. in fact, msdn says method signature: public void setdata<t> ( t[] data ) t : valuetype which same. so, fix this, you'll have pass in array of items value types, not reference types. is, instantiation of drawmodule<t> must drawmodule<valuetypehere> .
