When does Global Temporary table destroy in sql server? - i confused usage of global temporary table. have created global temporary table //session 52 : creator session create table ##temp(i int) insert ##temp(i) values(1),(2),(3) select * ##temp //session 56 select * ##temp //session 57 : lastly session holds refference of ##temp select * ##temp now if close session 52, ##temp table destroys. i believe global temp table released in next cases it's explicitly removed sessions the creator session closed , there no other sessions referencing session. i confused sessions referencing session(creator session) mean ? from create table : global temporary tables automatically dropped when session created table ends , other tasks have stopped referencing them. association between task , table maintained life of single transact-sql statement. means global temporary table dropped @ completion of lastly transact-sql statement actively referencing

calling a function from a different context using javascript? - im trying phone call function/method in javscript using oop style different context. for example: var someclass = function(){ this.init = function(){ var = "an interesting variable"; this.foo(something); //this works fine }, this.foo = function(bar){ alert(bar); } this.foo2 = function(){ this.foo(something); // deos not work/ not defined } }; var newclass = new someclass(); newclass.init(); newclass.foo2(); so want phone call this.foo() function within this.foo2() context, acting this.init() , im not sure makes sense, im new oop in javascript. your context right, you're trying access variable isn't defined in scope. variable something , declared var within init live within function. you need create fellow member of someclass : this.init = function() { this.something = 'an interesting variable'; this.f

Where is the proper place to put Python virtual environments according to the Linux Filesystem Hierarchy Standard? - as title asks, technically proper location store python virtual environments on linux operating systems according linux fhs? stated way allows clear answer: "technically correct" separate location of python virtual environment info files serving? note: this question differs closest, already-asked question find, virtual-environments contain libraries, binaries, header files, , scripts. as added complication, tend write code supports internet-accessible services. however, don't see substantially differentiating needs scenarios in consumers of service other processes on same server. i'm mentioning detail in case responses comments include "web dev"-esque content. for reference, using next documentation definition of linux fhs: http://www.pathname.com/fhs/pub/fhs-2.3.html i not believe popular virtualenv-wrapper script sugges
