permissions - Ruby on rails 4 - What would be the best way to allow one user to see the data of another user -

i want allow 1 user on app chose can see own data, don't know if i'm clear here example : user creates data on table , can see own data and/or decide share user. user b can see data user allowed him so. i thinking of random token generated when user created , user can decide share token else , display data based on token? it depends on "business rules" here. instance, in application developed read rights based on "privacy levels". privacy level 0 meant can view data whereas privacy level 1 denoted view data. of queries tailored datapoint, , model relation user denoted "owner." so in scheme, propose system each record has it's own permission token, system used in google docs. totally valid way of sharing records in system. more complex allowing users add users record, might optimal solution use case. anyway, few thoughts on subject. let me know if helps.

c++ - Debugging Stack corruption methods -

i'm facing stack corruption breakpoints right before @ return of wwinmain function.. can suggest me way, or tips of how debug stack corruption? (preferably in windbg) i know corruption occurs in procedure wrote in masm program, stack seems fine during whole procedure. rsp register has needs during whole time.. perform these in order: compile high level warning, , fix warnings run code analysis on project, , fix warnings - specially 1 says word buffer/array/stack etc. if corruption still not fixed, reduce function size (comment out upper or lower part of function). don't return - corrupting stack buffer may still allocated - commenting out omit bad-stack program code. refactor wwinmain - divide sub tasks (functions). 1 of function fail because of stack, , you'll locate real issue.

concurrency - pthreads locking scheme to allow concurrent reads of a shared data structure -

let's have code both reads , writes data structure. if have multiple threads executing code (and sharing data structure), there arrangement achieve following: allow 2 or more concurrent reads, no writes disallow 2 or more writes disallow 1 or more reads concurrently 1 or more writes a single mutex locked during read , write achieves goals 2 , 3, fails achieve goal 1. there solution achieves 3 goals? assume not possible devise scheme different sub-sections of data structure can protected different mutexes. my clunkly approach is: have 1 mutex per thread, , each thread locks own mutex when needs read. have 1 additional 'global' mutex. when thread wants write, first locks global mutex. goes through loop of pthread_mutex_trylock() on of thread-specific mutexes until has locked them all, performs write, unlocks them all. finally, unlocks global mutex. this approach seems not efficient, however. thanks in advance, henry pthreads includes r...
