作者此前将家庭局域网升级到 10Gb/s，但在炎热天气下，基于 Marvell 芯片的老款 10GBASE-T SFP+ 模块因过热而反复断开连接。为解决这一问题，作者更换为采用 Broadcom BCM84891 PHY 芯片的 10Gtek ASF-10G-T80-INT 模块。更换后链路稳定性显著提升，交换机 CPU 温度下降约 5°C，但新模块的 EEPROM 伪装成 Intel 光纤模块，导致无法通过 SNMP 直接监测温度。
The article details the discovery and diagnosis of a hardware bug in Intel 13th and 14th generation CPUs, specifically affecting the Oodle compression library. The bug was triggered under specific conditions, requiring workarounds to ensure system stability and correct operation of software relying on CPU instructions.
The article explains that data centers can connect to the electric grid faster if they agree to flexible power arrangements, such as reducing consumption during peak demand. This approach helps utilities manage grid strain while speeding up data center construction timelines.
Cohere released North Mini, a compact language model designed for developers to build and deploy AI applications efficiently. The model balances performance with accessibility, offering a smaller footprint for integration into various coding projects and environments.
Google Cloud launched Brazos, a liquid cooling system for air-cooled data centers that supports higher-power AI accelerators without major facility upgrades. It uses liquid-cooled rear-door heat exchangers and warm-water cooling to improve efficiency and sustainability. Brazos is being deployed for Trillium TPUs and Nvidia Blackwell GPUs.
This article explores using JTAG for hardware debugging and firmware extraction from SSDs. It covers identifying JTAG pinouts on a SSD controller, connecting a debugger, and using OpenOCD to interface with the device to dump firmware for reverse engineering analysis.
