SBC集群性价比极差,但乐趣无穷
上图中的是新型DeskPi Super4C,一款4节点树莓派CM5集群板,安装于8U迷你机架中。作者在测试该板卡的同时,协助启动了面向学生的单板集群竞赛(SBCC 2026),十几所大学团队在6000美元预算内搭建迷你HPC集群,并在数天内完成六项HPC工作负载的基准测试。

The iPhone 4 suffered from "Antennagate," a design flaw where holding the device in a certain way (the "death grip") caused significant signal loss. Apple acknowledged the issue in 2010 and offered free cases to affected users, later settling a class-action lawsuit over the problem.
A user successfully trained and ran a custom Piper text-to-speech model on a Raspberry Pi Zero 2W, demonstrating that low-cost, low-power hardware can handle on-device TTS inference. The project highlights the feasibility of deploying custom voice models on resource-constrained devices for offline applications.
Raspberry Pi Connect, the remote access service for Raspberry Pi devices, may soon gain the ability to remotely control Windows machines. The feature is being developed to allow users to connect to and control Windows PCs from a Raspberry Pi or other devices, expanding the functionality of the tool beyond Linux-based systems.
The Software Freedom Conservancy explains how AGPLv3 Section 7(4) allows users to remove "badgeware" requirements—such as mandatory branding in OnlyOffice and Nextcloud—by adding explicit permissions to the code, effectively overriding the licensor's additional terms.
A beta version of Raspberry Pi Connect for Windows has been released, allowing Windows users to remotely access and control a Raspberry Pi desktop from a Windows machine. The client app is available for download from the Raspberry Pi website and works with the existing Connect service on the Pi side.
