i wonder best practice ask user more information complete registration after social login passport. able sign in user through twitter, , callback route '/auth/twitter/callback' called. however, @ point i'm presenting form ask them few more pieces of information. problem @ point req.isauthenticated() returns true already, while i'd rather set isauthenticated manually after complete registration, not twitter callback called. suggestions? there few ways can achieve want , point of view fiddling around req.isauthenticated() not best. recommend following approaches. method 1 in addition req.isauthenticated() put new condition check whether user completed registration or not i.e. user.completedregistration() completedregistration() function checks either mongodb or other logic decide yes or not. sample follow: var isauthenticated = function (req, res, next) { if (req.isauthenticated() && user.completedregistration()) { //user both authenti

optimizing code better results in golang gc seems more of rather important thing time-optimized gc runs. told how accomplishes in run "depends on pattern of heap memory usage.", i'm not sure means/entails perspective of programmer in language. or not can controlled? i have read through recent book "the go programming language" brian w. kernighan, there nothing topic in it. , information on topic on internet years ago, don't apply. some things include: making sure pointers/objects ever stored/remembered need be allocating objects capacities of expected or sane not duplicating data when able, using streaming data through functions instead of putting data big heap front. i bit annoyed fact strings , byte arrays recreated when converting between 1 or other (due strings being immutable). when going 1 other, , safe operation, recast pointers other type using unsafe. are of these practices worth gc run faster , clear more? there else do?

according way understand threads, programming multi-threaded program either can speed program or match execution time of single-threaded version of program. so, 2 questions are: 1- said true or false ? 2- give example when multi-threading code produce negative results on performance ? a multi-threaded program can behave worse single-threaded equivalent. due to: the cost create additional threads the cost of context switches the potential false sharing . creating many threads small amount of work alters adjacent regions of memory exhibit of issues. multi-threaded programs in general introduce additional complexity , present numerous opportunities bugs. should taken account when deciding whether or not use multiple threads.

from documentation, class sklearn.linear_model.sgdclassifier(class_weight=none) like class_weight function, how give weights particular aspects of feature set? feature sets consists of raw text, , name. while training want give more weight name, , less weight raw text. how do that? there no option give weights features in sgdclassifier , , far know in no other learner in scikit-learn. in general, not make sense give different weights features. after all, machine learning because want computer figure out features more important. if name more important raw text classifier figure out internally. now, if still want have different features different importance can combine multiple classifiers: train 1 classifier using name feature, , train classifier using raw text features. combine output taking weighted average of each classifier's output. can give name -classifier higher weight, increase name 's impact on combined output.
