The solution is to negate your values when you store them in the heap, or invert your object comparison like so: import heapq class MaxHeapObj(object): def __init__(self, val): self.val = val def __lt__(self, other): return self.val > other.val def __eq__(self, other): re...
Growing the heap when there is not enough space isn't too hard since it can be implemented in the library call that handles the heap. However, growing the stack is often impossible as the stack overflow only is discovered when it is too late; and shutting down the thread of execution is...
The Python GIL, or Global Interpreter Lock, is a mechanism in CPython (the most common implementation of Python) that serves to serialize operations involving the Python bytecode interpreter, and provides useful safety guarantees for internal object and interpreter state. While providing many benefits...
GCs tend to have better memory locality and some are capable of compacting the heap making it less prone to memory fragmentation. .NET has a self-tuning, tracing GC. It aims to deliver “hands off” operation in the general case while offering configuration options for more extreme workloads....

Garbage Collection is a feature of Java programming language that automatically manages memory allocation and deallocation for objects created in an eden space.
One common technique is to divide theheap's memory space into three generations based on an object's longevity: All newly created objects start in the first generation. Short-lived objects, such as temporary variables, never make it out of this generation. The garbage collector identifies them ...
I stopped doing full Windows builds of open-source code locally (due to the heavy load and the fact that's a volatile and hard-to-repair environment). But, the single part I use from AppVeyor is now MSYS2, nothing else is in the PATH (exceptoptionallytheexternalmingw-w64 and Python fo...

I think that “<different options>” is displayed when you select “All Configurations” or “All Platforms” in dropdowns. In this case, some of the options are different, depending on configurations and platforms. The common values, such as _WIN32, are displayed directly. The values that...
