FlameGraph is a performance profiling and visualization toolkit designed to identify bottlenecks in software execution. It functions as a processing engine that transforms raw stack trace samples into interactive, hierarchical diagrams. By representing aggregated execution frequency as nested rectangles, the tool allows developers to visualize hot code paths and analyze system behavior across both kernel and user-space environments. The project distinguishes itself through its ability to perform differential profile analysis, which highlights performance regressions or improvements by compari

Twinkle Tray is a Windows display manager and DDC/CI monitor control utility designed to manage hardware settings across internal and external displays. It functions as a system tray application that allows for the adjustment of brightness, contrast, and volume on multiple monitors. The project provides multi-display brightness normalization to balance backlight levels across different hardware profiles for a consistent visual experience. It also includes an automatic brightness scheduler that modifies luminosity based on the time of day or system idle states. Beyond the user interface, the

gprof2dot is a performance graph generator and visualizer that converts gprof GNU profiler execution profiles into Graphviz DOT files. It transforms raw profiler data into a directed graph to map function call hierarchies and identify software bottlenecks. The tool employs heuristic-based color mapping to highlight performance hotspots by assigning colors to nodes and edges based on execution time percentages. It also supports differential profile analysis, allowing for the comparison of two distinct execution graphs to identify changes in timing and call counts between runs. To improve visu
