i know memory addressing can done multiples of word size intel 32 bits, allocating memory on stack in assembly can done //pseudo code sub , esp ,4 // allocating integer on stack sub esp, 8 // buffer of size 5 example b[5] so addressing done multiples of 4's. referring locals , parameters on stack done with // referring variable --ebp-4 but in disassembly see instructions like movb $0x41, 0xffffffff(%ebp) ,// refer ebp-1 example so refers memory 1 bytes. so refers 1 byte, not multiple of 4 bytes.the multiple of 4 bytes esp? or related every register? the multiple of 4 bytes esp? or related every register? note that sub esp, n doesn't access memory location, use related memory alignment instruction simple register-immediate subtraction, it use value. for performance reason if read 16 bits should on address multiple of 2, 32 bits should on address multiple of 4. called natural boundary alignment . 32 bit...

is there way check if 2 expressions mathematically equal? expected tg(x)cos(x) == sin(x) output true , outputs false . there way make such comparisons sympy? example (a+b)**2 == a**2 + 2*a*b + b**2 surprisingly outputs false . i found similar questions, none covered exact problem. from the sympy documentation == represents exact structural equality testing. “exact” here means 2 expressions compare equal == if equal structurally. here, (x+1)^2 , x^2+2x+1 not same symbolically. 1 power of addition of 2 terms, , other addition of 3 terms. it turns out when using sympy library, having == test exact symbolic equality far more useful having represent symbolic equality, or having test mathematical equality. however, new user, care more latter two. have seen alternative representing equalities symbolically, eq. test if 2 things equal, best recall basic fact if a=b, a−b=0. thus, best way check if a=b take a−b , simplify it, , see if goes 0. learn later function ca...

there constraints such x + y > 5 , x > 3 , y < 4, set of models x = 4 y= 3, given z3. dose z3 can give models incrementally, such set of models x=5,y = 2? thanks. regards can tell me please happens this: x,y = bools('x y') s = solver() s.add(or(x,y)) count = 0 while s.check() == sat , count <= 50: print s.model() s.add(or(x != s.model()[x], y != s.model()[y])) count = count + 1 print count the output is: [y = false, x = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y = true] [y ...

i try use spring+jpa+hibernat e , try inject entitymanagerfactory ,and later create entitymanger in code.but when use entitymanager.persist(user) ,the user not saving database .but when try inject entitymanager instead of entitymanagerfactory ,it worked !,i not know problem. you can see question more code. when using plain entitymanagerfactory instead of entitymanager need call createentitymanager . create new entitymanager , plain entitymanager not managed nor detected spring. have start/commit transactions yourself. when using entitymanager obtain transactional synchronized instance, managed spring , bound current transaction. no need start / commit transaction yourself. see jpa section of reference guide.

i attempting develop 'boardgame' sort-of application, simplicity sake let's think of monopoly familiar one. i've read bit long-polling , it's implications , got me confused stated need utilize framework (such socket.io) anyway, uses websockets , such. is possible avoid this? understand websockets better ajax request sitting , waiting response, reading on them made me bit "scared" of how implement such thing. not familiar node.js (though i'd love be) because understand has low hosting support providers , "overly complex use" or whatnot. generally speaking, since talking boardgame not need websockets use realtime client-server communication, because mainly, boardgames not intensive on simultaneous actions , not think there many changes communicate in short timeframe. might not understanding whole thing correctly correct me if wrong if game slow paced, such board games are, simple ajax request should suffice, no? if keep open in-defin...
