A blazing fast concurrent zip archiver. I was inspired to build pzip after I faced challenges boosting the performance of the Basecamp export pipeline at 37signals. pzip compresses files concurrently to take advantage of modern multi-core hardware. It also implements many other optimizations such as using pools to recycle file buffers and compressors to significantly reduce allocation overhead. Benchmarks on sample directories show pzip to be over 15x faster than the standard zip utlity.

Terminal is a web-based tool for testing and debugging webhooks. It provides an easy and convenient way for developers to test the behavior of their applications when receiving webhook requests. With Terminal, users can quickly set up a virtual endpoint to receive incoming webhooks, and inspect the details of each request, such as the headers and payload, in real-time.
