If speed is an issue, it’s way faster to bypass inspect module. testing depth: 50 (CPython 3.7.3) stacksize4b() | depth: 50 | 2.0 µs stacksize4b(200) | depth: 50 | 2.2 µs stacksize3a() | depth: 50 | 2.4 µs stacksize2a() | depth: 50 | 2.9 µs stackdepth2() | depth: 50 | 3.0 µs stackdepth1() | depth: … Read more
Apparently there is a hard limit on the stack size for mac os x, taken from http://lists.apple.com/archives/scitech/2004/Oct/msg00124.html granted this is quite old, and Im not sure if its still true anymore, but to set it simply call ulimit -s hard, its 65532. or about 65 megs. I did some tests on snow leopard, 10.6.8, and … Read more
When you call a function, a new “namespace” is allocated on the stack. That’s how functions can have local variables. As functions call functions, which in turn call functions, we keep allocating more and more space on the stack to maintain this deep hierarchy of namespaces. To curb programs using massive amounts of stack space, … Read more
Position the outer div however you want, then position the inner divs using absolute. They’ll all stack up. .inner { position: absolute; } <div class=”outer”> <div class=”inner”>1</div> <div class=”inner”>2</div> <div class=”inner”>3</div> <div class=”inner”>4</div> </div>
You have set symbol.MaxNameLength to 255, but you allocated “symbol” on the stack with IMAGEHLP_SYMBOL64 symbol;. That type is defined as: typedef struct _IMAGEHLP_SYMBOL64 { DWORD SizeOfStruct; DWORD64 Address; DWORD Size; DWORD Flags; DWORD MaxNameLength; TCHAR Name[1]; } IMAGEHLP_SYMBOL64; Notice that the Name field only has one character by default. If you want to store … Read more
Effective Java 2nd Edition, Item 16: Favor composition over inheritance: Inheritance is appropriate only in circumstances where the subclass really is a subtype of the superclass. In other words, a class B should only extend a class A only if an “is-a” relationship exists between the two classes. If you are tempted to have a … Read more
Your quote is from the “calling convention” part of the documentation. At the very least, you do not have to worry about this if you do not call other functions from your assembly code. If you do, then you must respect, among other things, “red zone” and stack alignment considerations, that the recommendation you quote … Read more
So long as you know what the semantics are, the only consequences of stack vs heap are in terms of making sure you don’t overflow the stack, and being aware that there’s a cost associated with garbage collecting the heap. For instance, the JIT could notice that a newly created object was never used outside … Read more
Just use the clone() -method of the Stack-class (it implements Cloneable). Here’s a simple test-case with JUnit: @Test public void test() { Stack<Integer> intStack = new Stack<Integer>(); for(int i = 0; i < 100; i++) { intStack.push(i); } Stack<Integer> copiedStack = (Stack<Integer>)intStack.clone(); for(int i = 0; i < 100; i++) { Assert.assertEquals(intStack.pop(), copiedStack.pop()); } } … Read more
iOS 5 introduced two new methods to handle exactly this type of situation. What you’re looking for is -[UIViewController isMovingToParentViewController]. From the docs: isMovingToParentViewController Returns a Boolean value that indicates that the view controller is in the process of being added to a parent. – (BOOL)isMovingToParentViewController Return Value YES if the view controller is appearing … Read more
