What Can You Do?

I was just in the bath tub, I take baths because it is the best place to think of this stuff, no place compares to the bath tub. I cannot stand taking a bath more than once per day however, and i’ve made it the way that I get clean. Just something about floating in the water causes you to think very clearly, and today in the bath came one of my greatest epiphany, … So that’s kinda weird sharing with you all that I sit in the bathtub every...

Window won't open
04/04/2025 by KSILVE040
I am writing some code using the Windows API to open a window. But, for some reason, the window won't open. I tried to use breakpoints to check the code line by line, but even breakpoints aren't working. When checking the output window, it says: The program exited with code […]
Is this non-blocking counter implementation correct?
04/03/2025 by Reisse
Let's pretend I'm writing code for some imaginary CPU which supports plain atomic load and store operations, but has no support for CAS or RMW. Can this non-blocking counter implementation be considered correct? namespace magic { template T atomic_load(T & location); // atomically reads value from memory template void atomic_store(T […]

I'm trying to make a GUI: #include #include "header/spgui.h" // Declare global variables without immediate initialization. GLuint VAO, VBO, EBO; GLuint shaderProgram; struct Vertex { glm::vec2 position; // (x, y) glm::vec2 texCoords; // (u, v) glm::vec4 color; // (r, g, b, a) }; // struct PageVertex { // Vertex Page; […]
Copying data from a user mode program to a shared section in a driver is causing a BSOD
04/03/2025 by 0xF4CE
My user mode program allocates memory for a communication struct UM_Msg (which contains a data member like this : BYTE data[256];) using the new operator like this: UM_Msg* ToDriver = new UM_Msg(); And then I copy it to a shared section between the driver and this program using RtlCopyMemory(). When […]
How to draw a line using volume coordinate? [closed]
04/03/2025 by Dastoger Bashar
I have written the following function to draw a line from screen (2D) coordinate, and it's working fine to display a line on the screen. void Graphics::DrawLine( long x1, long y1, long x2, long y2, CDC* memDC ) { if ( !memDC ) { memDC = m_memDC; } memDC->MoveTo(x1, y1); […]
How is the 'this' keyword set in C++?
04/03/2025 by IWannaAnswerQuestions
In C++, this is a pointer which refers to the current object/instance. Inside every member function, the this keyword is a pointer that holds the address of the current implicit object. But, I am very curious: How does C++ set the this keyword? Like, how is it defined in C++? […]
Race condition in observer pattern implementation by using std::weak_ptr [duplicate]
04/03/2025 by sakcakoca
I am trying to create a thread safe observer pattern implementation by keeping pointers of observer instances as std::weak_ptrs in the publisher. When I compile it with -fsanitize=thread and run it, thread sanitizer creates a warning indicating a race condition. Is there a way to fix this race condition and […]
Deleting final line in a text file in C++
04/03/2025 by Woodenplank
I have a program where a user can write (append) to a chosen text file for storing information. Each line should be two numbers, and a date string (YYYY-MM-DD). There a multiple different text files that the program might write to, say "foo.txt" "bar.txt", "stroustrup.txt," and the file contents might […]
Is it safe to access elements outside subrange but inside parent range?
04/03/2025 by hopeless-programmer
Let's say I have an std::vector arr of 5 elements { 1, 2, 3, 4, 5 }. Is it safe to get a subrange from it like sub = std::span{ arr.begin() + 2, arr.end() } and dereference element at -1 like *(sub.begin() - 1)? In terms of pointers this looks […]
