Explanation of everything you can see in htop/top on Linux, including load averages, process states, and memory usage.

Intel has started shipping high-volume logic chips made with ASML's High NA EUV technology, marking a significant milestone in the development of extreme ultraviolet lithography. The company is using High NA EUV to pattern selected Intel 18A layers, with products already shipping to customers at yields matched to those achieved on ASML's existing NXE EUV platform.

Telegram's t.me domain has been suspended, leading to outages and broken links worldwide. The suspension, which was implemented at the registry level, prevents the domain from resolving in the global Domain Name System (DNS).

The author delves into the complexities of reporting free or used memory in modern operating systems, specifically FreeBSD, and discovers issues with the `btop` tool. A fix is proposed and implemented, providing a more accurate representation of memory usage.

Exploring alternatives to run CUDA on non-Nvidia hardware, including HIP, SYCL, and ROCm.

Cloudflare's Images team found a race condition bug in the hyper HTTP library, causing truncated large image responses over sockets. The bug was fixed with a simple flush before shutdown.

SpaceX has applied to the FCC for permission to launch 100,000 more Starlink satellites, promising 'ultra-low-latency' multi-gigabit symmetrical broadband. The move could redefine the scale of satellite broadband, but faces opposition from astromers and rival services.

The QuadRF, a phased-array radio built around a Raspberry Pi 5 and an FPGA board, can spot drones and see WiFi through walls, raising concerns about security and surveillance. Its advanced signal processing and beamforming capabilities make it a powerful tool for both legitimate and malicious uses.

A new MPMC queue design ensures bounded waiting times, preventing starvation and ensuring efficient data transfer between producers and consumers. The queue's performance has been benchmarked, showing promising results.

Cloudflare introduces Meerkat, a globally distributed consensus service designed to handle strong consistency across its 330+ data centers. Meerkat uses QuePaxa, a 2023 algorithm that eliminates leader elections and timeouts, providing higher availability than traditional consensus algorithms like Raft.

NVIDIA’s 45 °C liquid‑cooling design eliminates traditional tower‑chiller water consumption and cuts cooling energy by up to 4 % per degree, but it also introduces new design constraints.

Google reports that IPv6 now carries 50% of its traffic, a milestone that forces enterprises to rethink network strategy and security posture.
