A distributed tracing system.
Zipkin is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in service architectures. Features include both the collection and lookup of this data.
If you have a trace ID in a log file, you can jump directly to it. Otherwise, you can query based on attributes such as service, operation name, tags and duration. Some interesting data will be summarized for you, such as the percentage of time spent in a service, and whether or not operations failed.

A research project to add some brrrrrr to Burp.
"burpference" started as a research idea of offensive agent capabilities and is a fun take on Burp Suite and running inference. The extension is open-source and designed to capture in-scope HTTP requests and responses from Burp's proxy history and ship them to a remote LLM API in JSON format. It's designed with a flexible approach where you can configure custom system prompts, store API keys and select remote hosts from numerous model providers as well as the ability for you to create your own API configuration. The idea is for an LLM to act as an agent in an offensive web application engagement to leverage your skills and surface findings and lingering vulnerabilities. By being able to create your own configuration and model provider allows you to also host models locally via Ollama to prevent potential high inference costs and potential network delays or rate limits.

The Apache® Hadoop® project develops open-source software for reliable, scalable, distributed computing.
The Apache Hadoop software library is a framework that allows for the distributed processing of large data sets across clusters of computers using simple programming models. It is designed to scale up from single servers to thousands of machines, each offering local computation and storage. Rather than rely on hardware to deliver high-availability, the library itself is designed to detect and handle failures at the application layer, so delivering a highly-available service on top of a cluster of computers, each of which may be prone to failures.
