Cloudflare tests Zstandard compression in Pingora to shrink cache storage

Cloudflare built a prototype called Cache Transcoding, developed during an intern project, that compresses eligible cached assets with Zstandard before writing them to disk inside its Pingora proxy. Assets stay compressed while stored and while moving between data centers via Tiered Cache, then get decoded only when served to the client. Early tests show this shrinks eligible assets to about a third of their original size with only a small CPU overhead.

Some Pixel 11 users report 5G, Wi-Fi and Bluetooth glitches despite new MediaTek modem

Google switched the Pixel 11 series from Samsung's Exynos modem to a MediaTek chip to fix years of connectivity complaints, but a subset of owners are now reporting 5G icons with no data, Wi-Fi dropouts, slow speeds, and network switching issues shortly after purchase. Reports have surfaced on Reddit from multiple Pixel 11 and Pixel 11 Pro XL owners, though many other buyers say their devices work fine.

Turso finds io_uring readahead cuts device requests 12x in TPC-H benchmark

A throwaway pull request to add readahead to Turso's io_uring backend became a case study in I/O performance. Without readahead, Turso issues one io_uring read at a time and waits for each to complete before requesting the next page; with a 32-page prefetch window enabled via PRAGMA, it submits many reads concurrently. On a TPC-H full-table scan, this dropped actual device requests from about 196,000 to roughly 16,300, while average request size grew more than tenfold and request-merging jumped from near zero to over 90%.

C++ blog details when compilers auto-move objects without std::move

A C++ programming tutorial explains that developers should rarely write std::move explicitly, because the language already applies return value optimization (RVO) and implicit moves in many common cases. The post walks through examples like pure RVO, named RVO, and functions returning parameters by value to show when the compiler elides copies or moves automatically.

JBL launches Cove Wi-Fi speaker line to challenge Sonos

NVIDIA's DLSS 5 debuts with NBA 2K27 amid backlash over AI-altered visuals

NVIDIA is launching DLSS 5, its latest AI upscaling technology, alongside NBA 2K27 on September 3. Early demos from Resident Evil: Requiem and Starfield drew heavy criticism for producing unnatural, over-processed character models, though NBA 2K27's implementation reportedly applies the effect more subtly with improved shadows and texture depth. The feature is exclusive to NVIDIA's RTX 50-series graphics cards.
