Are there problems with using GUID's as indexed fields in SQL Server? -

-
i've read lot of articles mention using guid clustered indexed (or primary key) in sql server cause performance issues. however, due design decisions, need field guid in each line of 1 table. if define primary key of table autoincrement integer, , add guid normal column indexed, have performance issues similar having guid primary key? edit: side note, know guid primary key bad idea, asking if have performance issues if set indexed (non clustered) field what type of index want use guid field? clustered? unique? if unique, guid not differ other unique field. can use without doubt. in case of clustered index affect performance. can use sequential guid . can solve performance issues. generating of guid on client-side can improve performance.

c++ - Decision trees / stumps with Adaboost -

i started learning decision trees adaboost , trying out on opencv , have questions. boosted decision trees i understand when use adaboost decision trees, continuously fit decision trees reweighted version of training data. classification done weighted majority vote can instead use bootstrapping when training decision trees adaboost ? i.e. select subsets of our dataset , train tree on each subset before feeding classifiers adaboost. boosted decision stumps do use same technique decision stumps ? or can instead create stumps equal number of features ? i.e. if have 2 classes 10 features, create total of of 10 decision stumps each feature before feeding classifiers adaboost. adaboost not trains classifier on different subsets, adjusts weights of dataset elements depending on assemble performance reached. detailed description may found here . yes, can use same technique train decision stumps. algorithm approximately following: train decision stump on initial data

ssh - How to open a shell without SSHD on the receiving end? -

-
i have machine without sshd , want open bash shell on machine remote machine (that can control). since have ssh on limited machine, configured reverse proxy: $ ssh -r 19999:localhost:22 remoteuser@remotemachine now have connection on port 19999 "fully control" machine "limited" machine. how open shell setup? you can pipe input port directly bash . common practice when misusing various bugs in software. example, run on full-access machine: nc -lvp 9999 and on limited machine /bin/bash -i >& /dev/tcp/192.168.122.1/9999 0>&1 where 192.168.122.1 ip of full-control machine. this give shell of second machine in first one. note connection not encrypted. if want encryption, need add tcp forwarding step (similar propose above).

javascript - Underscore.js, why does `isFunction` use `|| false`? -

the optional override isfunction(object) in underscore.js ( repo link definition ), reads follows: // optimize `isfunction` if appropriate. work around typeof bugs in old v8, // ie 11 (#1621), safari 8 (#1929), , phantomjs (#2236). var nodelist = root.document && root.document.childnodes; if (typeof /./ != 'function' && typeof int8array != 'object' && typeof nodelist != 'function') { _.isfunction = function(obj) { return typeof obj == 'function' || false; }; } what i'm confused || false , why necessary after string comparison? since typeof returns string there should no ambiguity? comment states override fixes typeof bugs, there cases on listed platforms when typeof doesn't return string? see issues covered in comments, #1621 , #1929 , #2236 . shortly put, platforms have bug typeof isn't string unless store in variable. || false fixes issue without introducing variable. t

javascript - Why Date.parse() methods works for invalid string "foo 01.01.01" -

-
i have doubt regarding javascript date.parse method, below code example var datestring = "foo 01.01.01"; date.parse(datestring) this returns value (978287400000) expect nan can perform invalid date check below. isnan(datestring.gettime()) my question how above string valid date string? per mdn link below should return nan. https://developer.mozilla.org/en/docs/web/javascript/reference/global_objects/date/parse thanks, michael from page link to: a string representing rfc2822 or iso 8601 date ( other formats may used , results may unexpected). from the spec page links to : if string not conform format function may fall implementation-specific heuristics or implementation-specific date formats.

ios - Running actions in sequence SpriteKit -

-
in ios app i'm trying animate distribution of cards of players. however, when try run action sequence, none of cards move. doing wrong? override func didmovetoview(view: skview) { /* setup scene here */ var actions = [skaction]() let cards = makedeck() c in cards { let card = card(key: c) card.position = cgpointmake(300, 300) addchild(card) actions.append(skaction.moveto(givecardtoplayer(cards.indexof(c)!), duration: 2.0)) } self.runaction(skaction.sequence(actions)) } change self.runaction(skaction.sequence(actions)) to cards.runaction(skaction.sequence(actions)) currently, running sequence of actions on scene rather cards. without seeing of other code i'd assume correct, if doesn't suggest posting code givecardtoplayer
