database - Storing Images in DB - Yea or Nay? - so i'm using app stores images heavily in db. what's outlook on this? i'm more of type store location in filesystem, store straight in db. what think pros/cons? i'm in charge of applications manage many tb of images. we've found storing file paths in database best. there couple of issues: database storage more expensive file scheme storage you can super-accelerate file scheme access standard off shelf products for example, many web servers utilize operating system's sendfile() scheme phone call asynchronously send file straight file scheme network interface. images stored in database don't benefit optimization. things web servers, etc, need no special coding or processing access images in file system databases win out transactional integrity between image , metadata important. it more complex manage integrity between db metadata , file scheme data it hard (within contex

java - Why are ListModel objects necessary? - let's have list called jlist1. we want create model it, of course, utilize listmodel object. done. defaultlistmodel<integer> numbers = new defaultlistmodel<>(); numbers.addelement(1); numbers.addelement(2); numbers.addelement(3); jlist2.setmodel(numbers); my question why utilize list model object instead of normal list or collection. reason know of setmodel() accepts list models argument, reason these decisions? if @ javadoc of defaultlistmodel realize provide several methods manipulate item in jlist not possible using simple collection. if initialize list array or vector, constructor implicitly creates default list model. default list model immutable — cannot add, remove, or replace items in list. create list items can changed individually, set list's model instance of mutable list model class, such instance of defaultlistmodel. please have @ swing tutorial on how utilize lists explained in

C++ : pointers to stack-dynamic variables - i new c++. don't quite understand why code not work. code have stack-dynamic variable? help. int twice(int x) { int *y; *y = x * 2; homecoming *y; } int *y; *y = x * 2; is not right because y points nowwhere, not allocated memory. undefined behavior. after line of code programme unpredictable , cannot assume behavior. you need allocate memory first using new or malloc , assign x*2 or pass address assign y into, i.e: int *y = new int( x * 2); example: int main() { int x = 4; int *y = new int( x * 2); cout << x << "," << *y; delete y; homecoming 0; } side note: unsafe homecoming pointer memory allocated in function because might become unclear , when responsible freeing allocated memory. in particular case there absolutely no apparent reason dynamic allocation way. c++
