ESP32 Bluetooth BLE issues with re-connecting
12/30/2024 by just4phil
i am working on a bluetooth BLE connection between 2 or more ESP32-S3 (wroom). At the moment there are one BLE Server and 2 BLE clients. I am sending some bytes from the server to all the clients as a broadcast to sync some action between them. This works really […]
Ergonomic loop splitting
12/30/2024 by BlueSky
I am looking for a more ergonomic way to do loop splitting in C or C++. Motivating example Imagine we want to blur all the rows of an image by convolving each row with the well-known {1, 4, 6, 4, 1} filter kernel. The first and last two pixels of […]
How do I use windows ncrypt API NCryptExportKey function, to get an unencrypted certificate key, in C/C++
12/30/2024 by John Rainey
I want to give access to a personnel certificate to another process, in PEM format. The process uses openssl. I successfully export the cert to a blob...but something is wrong. NCRYPT_KEY_HANDLE hExportKey is set to NULL, so I assume the blob is not encrypted. Is this a good assumption? When […]
Segmentation fault in memcpy when using a source pointer to an array [closed]
12/30/2024 by eliba
I have a program that looks like this: Buffers.h #define BUF_LEN 1200 extern uint16_t mybuf1[BUF_LEN]; extern uint16_t mybuf2[BUF_LEN]; Buffers.cpp uint16_t mybuf1[BUF_LEN] = { 0 }; uint16_t mybuf2[BUF_LEN] = { 0 }; MyCode.cpp #include "Buffers.h" void GetBuffer(int index, uint16_t *pData, int dataLen) { uint16_t *bufPtr = (index == 0) ? mybuf1 […]
Avoid warning in minimum alignment declaration [duplicate]
12/30/2024 by X1ngChui
I'm trying to use the always-zero bits in pointers for a bool value. Here's an example of the code: #include #include template struct alignas(2) Node { T elememt; Node* next; }; int main() { Node n; auto addr = reinterpret_cast(&n); assert((addr & 1) == 0); } However, when compiling this […]
In vector addition, why did the efficiency not improve despite increasing the number of CUDA threads?
12/30/2024 by dazhu
I tried to use CUDA to speed up vector addition. From add(N, x, y); to add(N, x, y);, the efficiency improved greatly. 65.409ms --> 3.0164ms (use nvprof) #include #include // Kernel function to add the elements of two arrays __global__ void add(int n, float *x, float *y) { int index […]
Best way to implement an access queue to a shared resource
12/30/2024 by Steens
I'm looking for adwice on the best method to implement an access queue to a shared resource. I created the following simple interface to access a third party api from a shell: #include #include #include "thirdparty_api.hpp" int main(int argc, char *argv[]) { if (argc < 2) return EXIT_FAILURE; std::cout tpapi_run […]
What is the fastest way to upcast std::shared_ptr<std::unique_ptr<T>>?
12/30/2024 by Andreev Gregory
Suppose class D is derived from class B. What is the best way to convert a std::shared_ptr to std::shared_ptr? The solution should not increment / decrement the std::shared_ptr counter and should not make copy of the std::unique_ptr. The naive approach does not work: #include struct B { virtual void msg() […]
Clang: constexpr variable must be initialized by a constant expression, but function is constexpr
12/30/2024 by Eliv_
The title is too short for the whole story. I am not a native English speaker, I apologize for any typo or wierd expression. I was learning magic_enum and trying to implement static enum reflection myself when I came across this issue. The code is too long to paste here: […]
Why doesn't RSS memory decrease when freeing memory in C++ with a thread pool? [duplicate]
12/30/2024 by Bleach3269
I'm working with a C++ code snippet that utilizes a thread pool to execute multiple tasks. In each task, I create a std::vector with 3 million elements. However, I'm noticing that the RSS (Resident Set Size) does not decrease after the tasks complete. #include "BS_thread_pool.hpp" #include #include #include #include int […]
