this regarding usage of arraylist returned class instance variable. class { //assigned list of string it. private list < string > newal; //returns list public list < string > getlist() { return newa1; } } class test { public void go() { list < string > list = a.getlist(); list.add(""); } } in test class when retreive list , manipulate list.because of reference ,class list got manipulated.if part of third party code.how correct code in test class original object wouldnt affected? the arraylist constructor takes collection can use that: list<string> list = new arraylist(a.getlist()); i think it's better this, depending on you're doing, may want construct new list in getter. helps type hiding.

[0, 1, 1, 1, 1, 1, 1] = 0 * (-2)^0 + 1 * (-2)^1 + 1 * (-2)^2 + 1 * (-2)^3 + 1 * (-2)^4 + 1 * (-2)^5 + 1 * (-2)^6 which gives (from bottom up) [0, 1, 1, 1, 1, 1, 1] = 64 - 32 + 16 - 8 + 4 - 2 = ...

i looking use elastic search mongodb support our full text search requirements. struggling find information on architecture , hosting , help. planning host es on premise rather in cloud. have mongodb running in replica set 3 nodes. how many servers required run elasticsearch high availability? what recommended server specification. thoughts 2 x cpu, 4gb ram, c drive: 40gb , d drive: 40gb how es support failover thanks tariq how many servers required run elasticsearch high availability? at least 2 what recommended server specification. thoughts 2 x cpu, 4gb ram, c drive: 40gb , d drive: 40gb it depends on amount of data you're indexing, amount of ram , (i'm assuming decent dual core cpu) should enough started how es support failover you set clustering multiple nodes in such way each node has replica of so in simple example cluster consist of 2 servers, each 1 node on them. you'd set replicas 1 shards in node, have back...

i have datagridviewcomboboxcolumn. want each of cells have possible values subset of bindinglist (let's call "master" bindinglist). 1 suggestion found online this: https://stackoverflow.com/a/14820929 but items in original bindinglist changing (new items added, old ones removed). there way make cells' items automatically updated when "master" binding list changed? you see if filteredobservablecollection fits needs. it's wpf take concept , adapt bindinglists. you can have many filtered wrappers want around single master list , each 1 acts separate list, operating (and notifiying) on subset matches filter supply.

i trying demonstrate work pal can change value of constant-qualified variable if wants (and knows how to) using trickery, during demostration, i've discovered exists 2 "flavours" of constant values: ones cannot change whatever do, , ones can change using dirty tricks. a constant value unchangeable when compiler uses literal value instead of value stored on stack (readed here ), here piece of code shows mean: // test 1 #define log(index, cv, ncv) std::cout \ << std::dec << index << ".- address = " \ << std::hex << &cv << "\tvalue = " << cv << '\n' \ << std::dec << index << ".- address = " \ << std::hex << &ncv << "\tvalue = " << ncv << '\n' const unsigned int const_value = 0xcafe01e; // try no-const reference unsigned int &no_const_ref = const_cast<unsigned int &>(const_valu...

this question has answer here: naming conflict built-in function 7 answers i asked add feature code written other guys. there python code defines function overwrites build in open function def open(xxx): ... i access original open function in same python file. the best way change name of self defined open . prefer not change since hug system may have many other files access method. so, there way access build in open if has been overwritten? python 2: >>> import __builtin__ >>> __builtin__.open <built-in function open> python 3: >>> import builtins >>> builtins.open <built-in function open> don't use __builtins__ : from docs : cpython implementation detail: users should not touch __builtins__ ; strictly implementation detail. users wanting override values in builtins namesp...

i have matrix of returns x assets. i can plot cumulative performance this: pnls.cum<-apply(pnls.allin , 2 , cumsum) plot(pnls.cum[,1],type="l") or chart.cumreturns(pnls.allin[,1]) but graphs subtly different (highs/lows etc) . there reason why? chart.cumreturns uses geometric chaining (a product) default, not arithmetic chaining (a sum). set geometric=false : chart.cumreturns(pnls.allin[,1], geometric=false)

i'd run grid search cross-validation on probability outputs of svc classifier. in particular i'd minimize negative log likelihood. documentation seems gridsearchcv calls predict() method of estimator passed , predict() method of svc returns class predictions not probabilities ( predict_proba() returns class probabilities). 1) need subclass svc , give predict() method returns probabilities rather classes accomplish log likelihood cross validation? guess need write own score_func or loss_func ? 2) cross-validating on negative log likelihood dumb? i'm doing b/c dataset is: a) imbalanced 5:1 , b) not @ separable i.e. "worst" observations have > 50% chance of being in "good" class. (will post 2nd question on stats q&a) yes, would, on both accounts. class probsvc(svc): def predict(self, x): return super(probsvc, self).predict_proba(x) i'm not sure if work since majority class may still dominate log-like...

i have excel file(.xls) contain date column without time value. trying read file , put in datatable connection string below: provider=microsoft.jet.oledb.4.0;data source=c:\users\test\desktop\1.xls; extended properties="excel 8.0;hdr=yes;imex=1;importmixedtypes=text" excel file data oledb return datem value time. 7/20/1995 12:00:00 am datatable data but want datem column value without time. have idea have solve problem. thanks. .net framework's datetime consist of date , time. can't separate time part datetime , instead can use custom format displaying records. string str = datetime.today.tostring("mm/dd/yyyy");

i writing component descends tlistview, , want know when developer using component adds column can react. how can detect when new column added? there event? there no such event, since component writer, events off-limits anyway. events developers using component. columns added sending control lvm_insertcolumn messages. override message handler in descendant control: procedure lvminsertcolumn(var msg: tmessage); message lvm_insertcolumn; implement call inherited handler, , whatever want. procedure tlistviewdescendant.lvminsertcolumn(var msg: tmessage); begin inherited; // todo: custom handling end;

we facing problems due high amount of cached objects. cache data erp system (for online shop) , iis refresh webpage reaches maximum amount of memory , loose cashed objects. makes idea of caching little bit problematic searching solution cache objects different solution. i have found appfabric microsoft included our windows server licenses pretty neat solution. how ever still fear have enormous performance problems when using appfabric velocity instead of memorycache class (our current solution caching). so question now, solution our problem or over-thinking here , performance of appfabric fast enough? grid dynamics did great report on using appfabric here . while don't know numbers specific cache operations, report showed great numbers performance wise appfabric. in 1 test, wanted see how size of cache impacted cache operations performance. when reading data, had little no impact on cache operations performance. when updating, there impact on cache operations per...

i have pretty awkward problem query won't insert medium/large texts. when try example insert/update database records tester works, when try insert/update 4 lines of text, doesn't (won't give me error either). strange part process 2 'lorem ipsum' paragraphs. my query looks (for insert): $ncp_id = $defaults->query("insert ".$table[0]." (p_id, p_title, p_date, p_desc) values ('','".$_post['p_title']."','".$_post['p_date']."','".$_post['p_desc']."')"); $defaults->query("insert ".$table[2]."
