Cluster Server R2 2U rack cluster server ships with up to 72 Rockchip RK3399/RK3328 SoMs

Rockchip RK3399 and RK3328 are typically used in Chromebooks, single board computers, TV boxes, and all sort of AIoT devices, but if you ever wanted to create a cluster based on those processor, Firefly Cluster Server R2 leverages the company’s RK3399, RK3328, or even RK1808 NPU SoM to bring 72 modules to a 2U rack cluster server enclosure, for a total of up to 432 Arm Cortex-A72/A53 cores, 288 GB RAM, and 18 3.5-inch hard drives. Firefly says the cluster can run Android, Ubuntu, or some other Linux distributions. Typical use cases include “cloud phone”, virtual desktop, edge computing, cloud gaming, cloud storage, blockchain, multi-channel video decoding, app cloning, etc. When fitted with the AI accelerators, it looks similar to Solidrun Janux GS31 Edge AI server designed for real-time inference on multiple video streams for the monitoring of smart cities & infrastructure, intelligent enterprise/industrial video surveillance, object detection, recognition & classification, smart visual analysis, and more. There’s no Wiki for Cluster Server R2 just yet, but you may find some relevant information on the Wiki for an earlier generation of the cluster server.

• Linux fmt Command – Formatting Text on the Command Line

  The fmt command is a text utility included in the GNU Core Utilities. It was originally created to format email messages at the command line. However, it can be very useful for reading any text files in the terminal. Sure, modern terminals will wrap text to fit in the window.

Contributing to KDE is easier than you think – Bug triaging

Today, 2021-01-28, is the Plasma Beta Review Day for Plasma 5.21, that is to say, Plasma 5.20.90. Right now it’s a bit after 2 a.m., so after this I’m going to bed so I can be present later. This month I’ve mostly been enjoying my post-job vacation as last year I was bordering burnout. As such I didn’t help much. Before bed I’ll be providing a few things I’ve learned about triaging, though. While this blog post isn’t specifically about the Beta Review Day, this should make the general bug triaging process clearer for you, making it quite timely.
