Ceki Gülcü's Projects
Collection of various algorithms in mathematics, machine learning, computer science, physics, etc implemented in C for educational purposes.
A memory-efficient implementation of a compressed generalized suffix array
Compression algorithms techniques: LZ77, LZW, Standard Huffman, Adaptive Humman, quantizer, and predictive feed forward
Find duplicates based on SHA-512
Bogus plugin for testing slf4j integration in Maven 3.1
Dummy EAR project
Different Java Loggers Benchmarks.
JNDI注入测试工具(A tool which generates JNDI links can start several servers to exploit JNDI Injection vulnerability,like Jackson,Fastjson,etc)
Shows an unexplained performance issue in a debug log scenario on Windows.
Bringing back Groovy to Logback for configuration.
Performance related project
A small application for testing/illustrating logging separation
An XML Schema Definition for logback
The project is a simple vulnerability Demo environment written by SpringBoot. Here, I deliberately wrote a vulnerability environment where there are arbitrary file uploads, and then use the `scan` attribute in the loghack configuration file to cooperate with the logback vulnerability to implement RCE.
Jira archive for Apache Lucene
This repository contains a Java implementation of the LZ-77 data compression algorithm. LZ-77 is a lossless data compression method that replaces repetitive sequences of characters with references to previously occurring data. It achieves compression by storing the position and length of a match in a sliding window of previously processed data.
