[$] An update on the scraper situation

Our article "Fighting the AI scraper bot scourge", published in early 2025, discussed the problem of widespread scraping of web sites in search of training data for large language models and related projects. This activity overwhelms sites with traffic. Over a year after that article is published, the problem is still growing. The hammering of sites by shadowy actors has reached new heights, and the open web is becoming increasingly difficult to maintain. Where is this traffic coming from, and what can be done about it?

[$] QBE 1.3: metaprogramming, performance, and cross-platform support

QBE, a compact compiler backend developed by Quentin Carbonneaux, is a lightweight alternative to larger compiler backends such as LLVM and GCC. Designed to be small enough for a single developer to understand, QBE uses a static single-assignment (SSA) intermediate representation (IR), supports the C ABI, and serves as the backend for projects such as Hare and the cproc C11 compiler. Frontends emit the textual form of QBE's IR directly; QBE then takes care of register allocation, optimization, and native-code generation, producing assembly for the target architecture.

Linux DT Patches Provide Very Basic Support For Apple M3 Pro / Max / Ultra

Upstreamed for the Linux 7.2 kernel was initial support for booting Linux on the Apple M3 SoC devices. But just the barebones suppport for booting with not yet any accelerated graphics or other typical function needed for daily use of M3 Apple devices on Linux, just booting to a console. Now this work is complemented by additional Device Tree patches for also booting M3 Pro / Max / Ultra devices on Linux...

LLVM Clang Merges Initial Support For NVIDIA Rigel Core With Next-Gen Rosa CPU

Earlier this week NVIDIA confirmed some basic details around their next-gen Rosa CPU that succeeds Vera. Among the public confirmation was that it will feature a "Rigel" Armv9.2-A core iterating on their Olympus core design. With the basic details published, NVIDIA immediately introduced Rigel core support into the GCC compiler. Now they have also upstreamed their initial Rigel core enablement into the LLVM Clang compiler...
