ssh-add ~/.ssh/id_ed25519How to check “gperftools” version based on “tcmalloc” library?
strings <path>/libtcmalloc.so | grep -i "gperftools"
or
grep -ao "gperftools [0-9.]*" <path>/libtcmalloc.so
-a: forces it to read the binary as text.-o: tells it to only print the matching version string instead of dumping a massive wall of corrupted binary text into your terminal.
How to check the root cause of the difference between “pytest” and “python -m pytest”?
| Command | Uses which Python? | Risk |
|---|---|---|
pytest | Whatever executable is first in PATH | May run wrong environment |
python -m pytest | The Python you explicitly called | Much safer |
cat $(which pytest)The shebang line can show which “python” that pytest uses.
python -c "import sys; print(sys.executable)"or
which pythonThis shows the interpreter you’re explicitly invoking.
Null response caused by an extra space
<URL>/<Stage>/<Resource>For example, <Resource> is supposed to be "find-or-create-game-session". But if "find-or-create-game-session "(an extra space in the end), "<URL>/<Stage>/find-or-create-game-session " will be invalid.
This happened in Unreal Engine (5.4.4), DA_GameSessionsAPIData->Resources, incorporated with AWS GameLift.
Use getrusage() to check memory usage
To check the memory usage of a C++ program on POSIX-compliant systems (like Linux, macOS, BSD) using getrusage, you can access the ru_maxrss field of the rusage structure. This field provides the maximum resident set size (maximum amount of physical RAM used) in KB.
#include <sys/resource.h>
#include <iostream>
struct rusage usage;
if( getrusage(RUSAGE_SELF, &usage) == 0 ) {
std::cout << usage.ru_maxrss / 1024 << " MB" << std::endl;
