What actually causes a Stack Overflow error? [duplicate]
...ve programs, when there is a risk of writing into memory that had not been allocated for the buffer, and thus to corrupt some other memory locations. It's not the case at all.
JVM has a given memory allocated for each stack of each thread, and if an attempt to call a method happens to fill this mem...
Case insensitive 'Contains(string)'
... >= 0? That uses the right culture and is case-insensitive, it doesn't allocate temporary lowercase strings, and it avoids the question of whether converting to lowercase and comparing is always the same as a case-insensitive comparison.

Reset C int array to zero : the fastest way?
...imized by hand.
memset(myarray, 0, sizeof(myarray)); // for automatically-allocated arrays
memset(myarray, 0, N*sizeof(*myarray)); // for heap-allocated arrays, where N is the number of elements
By the way, in C++ the idiomatic way would be to use std::fill (from <algorithm>):
std::fill(...
Why is C so fast, and why aren't other languages as fast or faster? [closed]
...ere is no overhead, but that means that the programmer needs to be able to allocate memory and free them to prevent memory leaks, and must deal with static typing of variables.
That said, many languages and platforms, such as Java (with its Java Virtual Machine) and .NET (with its Common Language R...

'rlimit' is related with amount of memory allocated to process. Its os thing. In this case memory allocated to mongod process. So mongodb complaining you that memory allocated is low & it might be slow. I guess thats ok on development machine. But if you reading ...

>>> x = np.arange(n)
>>> reps = 10000
Zero-cost allocations
A view does not take any additional memory. Thus, these declarations are instantaneous:
# New axis
x[np.newaxis, ...]
# Broadcast to specific shape
np.broadcast_to(x, (reps, n))
Forced allocation

Is it possible to use global variables in Rust?
...
It's possible but no heap allocation allowed directly. Heap allocation is performed at runtime. Here are a few examples:
static SOME_INT: i32 = 5;
static SOME_STR: &'static str = "A static string";
static SOME_STRUCT: MyStruct = MyStruct {

Fatal error: cannot allocate memory for the buffer pool

How much memory is on your instance? Should there be enough memory to accommodate the 512M InnoDB is trying to grab for the buffer pool, plus everything else...
