scala - Cross-cutting "logical" scopes in multi-project sbt builds - let's have build handful of subprojects related have logical classification above sorts of things build aware of. for example, might have collection of subprojects foo bar baz quux woof oink i know woof , bar part of i'd phone call server component. baz mutual dependency of both, , foo, quux, , oink on client side. whole build aggregate of various subprojects, i'd "focus" on server side, or client side, or whatever. on 1 hand, i've considered nested aggregated projects, i'm not sure how works sbt's other functionality. on other, thinking of making custom scopes cutting across subprojects. i'd able configure related projects similar keys, handy able i'd update key grouping of related projects. what's approach sort of thing? thinking wrong? dealt similar situation. my solution break things out sub-projects in sbt, , utilize dependson

ruby on rails - Circular dependency when trying to reopen an engine class? - i trying re-open class in rails comes engine. did following: module xaaron apikey.class_eval include promiscuous::publisher publish :xaaron_users_id, :api_key, :as => :apikey end end which sits in: models/ xaaron/ api_key.rb this in app, should allow me run: bundle exec promiscuous publish "xaaron::apikey.all" but, when do, error: runtimeerror: circular dependency detected while autoloading constant xaaron::apikey tl;dr: seek renaming api_key.rb else. here i think happening: rails autoloader loads xaaron/api_key.rb , encounters unknown constant xaaron::apikey . tries load file called (based on constant name)... xaaron/api_key.rb . boom, circular dependency. ruby-on-rails ruby class-eval

memory leaks - WinDbg with dump files when you have a classic ASP app which uses a lot of .Net via interop - ok, first please don't inquire why application way is. classic asp application in several areas uses .net , com , of .net reaches com! it's code reuse really, @ point .net introduced , used whole load of features, required within classic asp app , voile! kind of hellish beast appeared. so question? can see looks serious memory leak in application (it's 32 bit) private bytes rocket 900mb+ , users start receive out of memory errors , odd issues part of page beingness rendered. took perfmon logs , added user action tracing code , tied info trace perfmon (working set , private bytes on w3wp). told me few things, did find issues with, "resolved" , release - though had no impact. stress test on app based on actions in iis logs, told me nil - can't replicate @ locally. so got memory dump when hits around 900mb , analysing windbg. problem -

java - Array in Array, what should be tracing of this code? - int[] ar=new int[5]; int[] numoccurence = new int[ar.length]; (int = 0; < ar.length; i++){ ++numoccurence[ar[i]]; system.out.println(numoccurence[ar[i]]); } first of there no array in array. -if mean line, int[] numoccurence = new int[ar.length]; then nil passing length of ar[] create new array -if mean line, ++numoccurence[ar[i]]; or numoccurence[ar[i]] . 1 time again incrementing values in numoccurence[] , providing index of values based on values in arr[] , ( arr[i] returns int ) an array of array this:- integer[] array1 = new integer[]; integer[] array2 = new integer[]; integer[][] arrays = { array1, array2}; here arrays holds references arrays, integer reference arrays. and said in comments code nil print 1,2,3,4,5. and asked how code works, since not assigning values in array ar or numoccurence , values in them initialized 0. , hence in each iteration of loop
