A GIF security scanner that parses GIF87a/89a byte streams itself and runs seven detectors on the regions a renderer never draws.

• Detects GIFAR, trailer-appended payloads, content-sniffing XSS polyglots, embedded web shells and gifshuffle steganography.
• Combines signature matching with Shannon entropy to flag encrypted or packed payloads, and reports their offsets.
• Cuts false positives by scanning only renderer-ignored regions and stripping power-of-two palette padding from LZW data.
• Self-registering plugin architecture; JSON, CSV and ANSI reports; contractual exit codes for CI.
• GitHub Actions matrix across Python 3.11–3.13.

Everyone means to set up aliases and never does — and when they do, they guess. histwise answers the question with your own data.

• Parses bash, zsh and fish history formats and shows what you actually type most.
• Ranks alias candidates by (command_length − alias_length) × times_used: real keystrokes saved, not raw counts.
• Ships as a single static binary. Fully offline, never phones home, never modifies your history.
• histwise --aliases >> ~/.bash_aliases and you’re done.

Predicting fusion power output, comparing a physics-informed neural network against standard networks. Built for CHE657 under Prof. Salman Khan.

• Designed a custom physics-based loss that enforces steady-state fusion power laws, so predictions stay physically consistent.
• Preprocessed and normalised 10,000+ experimental runs, scaling extreme values for numerical stability.
• Compared models on error metrics: the PINN generalised better with physically grounded outputs.
