Levent Kaya — Technical Blog and Notes

C and C++ deep dives into OS internals, graphics, debugger internals, and retrocomputing.

Linux systems programming, CPU emulation, graphics from scratch, and retrocomputing — all implemented in C or C++, with full source code. Active projects: fbgl, a zero-dependency Linux framebuffer graphics library; BoltDbg, a debugger built on ptrace; c6502, a MOS 6502 emulator and debugging suite
