[$] SFrame-based stack unwinding for the kernel

2 hónap óta
The kernel's perf events subsystem can produce high-quality profiles, with full function-call chains, of resource usage within the kernel itself. Developers, however, often would like to see profiles of the whole system in one integrated report with, for example, call-stack information that crosses the boundary between the kernel and user space. Support for unwinding user-space call stacks in the perf events subsystem is currently inefficient at best. A long-running effort to provide reliable, user-space call-stack unwinding within the kernel, which will improve that situation considerably, appears to be reaching fruition.

[$] Anubis sends AI scraperbots to a well-deserved fate

2 hónap 1 hét óta

Few, if any, web sites or web-based services have gone unscathed by the locust-like hordes of AI crawlers looking to consume (and then re-consume) all of the world's content. The Anubis project is designed to provide a first line of defense that blocks mindless bots—while granting real users access to sites without too much hassle. Anubis is a young project, not even a year old. However, its development is moving quickly, and the project seems to be enjoying rapid adoption. The most recent release of Anubis, version 1.20.0, includes a feature that many users have been interested in since the project launched: support for challenging clients without requiring users to have JavaScript turned on.
