AddLet agents test your code in a real browser.
One command scans your unstaged changes or branch diff, then generates a test plan, and runs it against a live browser.
Expect reads your unstaged changes or branch diff, sends them to an AI agent (Claude Code or Codex CLI), and generates a step-by-step test plan describing how to validate the changes. You review and approve the plan in an interactive TUI, then the agent executes each step against a live browser - using your real login sessions so there's no manual auth setup. Every session is recorded so you can replay exactly what happened.

noq, a QUIC implementation in Rust.
General purpose implementation of the QUIC transport protocol in pure Rust. Noq is built as an async-friendly API in the noq crate on top of a sans-io protocol library in noq-proto.
Noq started out as a fork of the excellent Quinn project. The main focus of development has been towards adding support for more QUIC (draft) extensions.

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications.
