Project : ### Cute Floating Ghost : July 2023 | Shader, GLSL, Ray marching : This animation was created using ray marching and shader math. I draw the ghost that floats and moves in the ocean! : There will be a blog post about this! Stay tuned! : ### Ascii art web server : April 2023 - May 2023 | Server, Concurrency, OS : This project created a server with a web interface that takes a URL to an image and converts it to ASCII art. The server spawns worker threads and spreads the incoming connections to the different workers to allow concurrent processing. The server experiments with the new proc_fd and the ability to pass file descriptors to a different process. : ### Padding Oracle On Custom Padding Methods : March 2023 - April 2023 | Cryptography, Block Cipher : Discovered efficient attack method against novel padding method proposed in this conference paper : Created a CTF challenge based on the attack method in HITCON CTF : ### Vulnerability Explorer : January 2023 - present | Python, Flask, Compiler | !Note that this project is still in the idea phase : Visualized execution of vulnerable program graphically for better comprehension : Implemented a simplified compiler for easy experimentation : ### mktmpdir : January 2023 | Shellscript, Bash : This is a simple shell script that drops the user into a temporary folder. This script allows users to do simple experiments without worrying about messing up the folder structure. The script supports keeping the result of the temporary folder and naming the session : ### Raspberry PI Remote Display Server : December 2021 | Python, Flask, LCD display : Designed Interaction between web server and hardware LCD screen : Allowed easy management of remote display with real-time monitoring : Implemented a simple database for swapping previously displayed images : ### Ferris Sweep Keyboard : December 2021 | Micro-controller, Keyboard, Soldering : I attempted to create my own keyboard using the ferris sweep 34 key design. I used nice-nano microcontroller along with the zmk firmware to support Bluetooth connection. The link above goes to the zmk config I used during the build. : ### This Blog Website : September 2021 - current | Jekyll, Markdown, HTML, CSS : This website is originally created from a jekyll blog website template by Chad Baldwin . I later expanded the website to suit my needs. : The components updated include: : - The theme for the navigation bar : - Tag filter in page archive, taken mostly from TeXt theme : - A separate about-me page : - Back to top button : Link to source code: https://github.com/bronson113/bronson113.github.io : ### Code Optimization on Pattern Matching Algorithm : June 2021 | C++, Optimization, Cache : Implement the FM-index algorithm under the ideal time complexity : Applied optimization such as loop unrolling and compression to minimize cache miss-rate : Achieved 41x runtime efficiency compared to the naive implementation : ### Adversarial Example Generator : July 2019 | Machine Learning, Python : Adversarial Examples are inputs that are wrongly identified by machine learning models. This project aims to create a model to automagically generate adversarial examples. : This is a project at AIS3 2019 and won the best project award : ### Battle Starship : January 2018 : This is a minigame made in single page html + javascript : Credit to donnie9171 for the original idea and prototype in Scratch.
