- 7GitHub Blog·9/24/2026securityGitHub Security Lab adds AI-powered fuzzing taskflow
GitHub Security Lab introduced the Fuzzing Taskflow, an autonomous pipeline that uses an LLM agent to analyze C/C++ repositories, generate harnesses, run AFL++, inspect coverage, triage crashes, and produce vulnerability reports. The workflow is built on the GitHub Security Lab Taskflow Agent framework and is available through a GitHub repository and Codespace setup.

Rust Glancer is an alternative Rust language server built to use far less RAM than rust-analyzer, with a target of under 100 MB for typical projects. It also preserves analysis results on disk so indexing can be restored immediately after an editor restart, though the project is still incomplete and has known limitations.
- 4Hacker News·8/10/2026researchTail-call optimization in C is now practical in GCC and Clang
The post argues that tail-call optimization in C was historically limited by calling-convention constraints and was not broadly available in older compilers. It notes that modern GCC and Clang can now perform the kind of tail calls needed for interpreter dispatch, enabling techniques such as direct-threaded code and large-scale snippet generation. The discussion cites Gforth and WebAssembly interpreter implementations as examples of why this matters.

Clawk is an open-source tool that lets coding agents run inside disposable Linux virtual machines instead of directly on a developer’s laptop. The project is aimed at reducing risk when agentic tools execute code, install dependencies, or make system changes locally.
- 5Hacker News·7/11/2026researchBranchless quicksort gets faster with compiler-friendly style
The article shows that modern compilers, especially Clang, can generate fast branch-free code for optimized Quicksort when the implementation is written in a specific style. It demonstrates sorting-network-based macros and branchless compare-and-swap patterns as a way to influence optimization results.
