Designing the Raspberry Pi 5: Insights from James Adams and Eben Upton

Raspberry Pi has recently released the highly anticipated Raspberry Pi 5, and it’s been a culmination of years of hard work and decision-making. In an interview with Eben Upton, the co-founder of Raspberry Pi, James Adams dives deep into the design process behind this new iteration of the popular single-board computer. The conversation between Adams and Upton is lengthy and comprehensive, covering all aspects of the design process. For those who prefer watching, there is a video available on the Raspberry Pi YouTube channel.

Linux 6.7 Indicates Disabled AMD SVM Virtualization in /proc/cpuinfo

Phoronix reports that Linux will now indicate via /proc/cpuinfo if AMD virtualization (SVM) is disabled. This is a quality of life improvement for home lab virtualization when using AMD CPUs. Previously, checking for the presence of Intel virtualization support and its status could easily be done by looking at the flags in /proc/cpuinfo. However, SVM was always shown in /proc/cpuinfo regardless of whether it was disabled in the BIOS. This oversight is finally being corrected in the upcoming Linux 6.7 kernel cycle, with the possibility of back-porting the fix to existing kernel series.

The patch, developed by Red Hat’s Paolo Bonzini, has been queued into TIP’s x86/cpu branch. This patch will now read the appropriate MSR to verify if SVM has been disabled on AMD and Hygon processors. If SVM is disabled, the CPU capability will be cleared, and it will no longer show in /proc/cpuinfo. Previously, the only indication of AMD SVM being disabled was appearing in the kernel log or KVM virtualization failing to work. This small but useful change makes it much easier to check if virtualization is available via the widely-used /proc/cpuinfo interface.

GLAuth Releases Version 2.3.0: Lightweight LDAP Server for Development, Home Lab, or CI/CD

Go-lang LDAP Authentication (GLAuth) has released version 2.3.0 of its lightweight LDAP server, providing a secure and easy-to-use solution for development, home lab use, or CI/CD environments.

The release introduces both new features and bug fixes to enhance the functionality and stability of the server software. However, it is important to note that there is a breaking change in this version, as the groups table has been renamed to ldapgroups.

The main feature of the v2.3.0 release include an update to the migration code, which now supports table names. In addition to the new feature, a bug fix has been implemented in this release, also regarding ldapgroups.

With this latest release, GLAuth continues to provide a reliable and efficient LDAP server solution for users in development, home lab, and CI/CD environments. The project’s commitment to security, ease of use, and continuous improvement is commendable.

Jellyfin Issues Call for Developers

Jellyfin, an open-source media streaming server, has issued a call for developers to join their project and help make it better. As an explicitly anti-commercial platform, Jellyfin relies on a team of volunteers who contribute their time and skills to improve the server, the web interface, and clients. However, the team is currently under strain, with a small core contributor base and a lack of new developers joining the project.

One of the biggest complaints about Jellyfin is the lack of client support and the rough edges in its interface. The team acknowledges these concerns and wants to address them. They are seeking volunteers who can help make the code better, write new code, improve documentation, and contribute to the overall development of the project. They are particularly interested in finding developers, writers, UI/UX designers, non-English language speakers, and enthusiastic individuals who are willing to help.

Jellyfin provides resources and support for new contributors, including active chat channels and forums where the team is available to assist. They emphasize that every contribution, no matter how small, can make a difference in improving the software. They also have an official process for individuals to join the team after proving themselves through quality contributions and a willingness to participate.

The goal of Jellyfin is to address user concerns, limitations, and bugs, and to create the best streaming server possible, free for everyone forever. By joining the project, developers have the opportunity to help shape the future of Jellyfin and make media streaming accessible to a wider audience.

Jellyfin calls on the wider community to support their project and contribute their skills and ideas to help make Jellyfin better. Whether you are a developer, writer, designer, or simply an enthusiast, your help is needed to push the project forward and turn Jellyfin into the ultimate streaming server.

Introducing the PALMSHELL NeXT H2: Affordable 10GbE Micro Server

The PALMSHELL NeXT H2 is an affordable micro server and single-board computer (SBC) powered by an AMD Ryzen Embedded R1505G processor. It offers impressive networking capabilities with two 10GbE SFP+ cages and one 2.5GbE RJ45 port. The system also supports up to 32GB of RAM and has storage options including an M.2 NVMe SSD and two SATA drives. It features wireless connectivity options such as WiFi 6, Bluetooth 5.2, and the possibility of adding a 4G LTE or 5G module. These network features make it an interesting option for various homelab uses. Theoretically, the device could support ECC memory as the Ryzen Embedded R1505G has such support, but this is not mentioned in the specifications for the NeXT H2 specifications, although it is mentioned in the specifications for the CPU. It should be noted that such support also depends on motherboard and firmware, not just on the CPU.

The system is equipped with a customized copper heatsink and a 3000 RPM PWM speed control fan for efficient cooling. It can be powered by a 12V to 19V DC power supply. The PALMSHELL NeXT H2 is designed to support multiple operating systems, including Ubuntu, Arch Linux, Fedora, Debian, OpenWrt, Windows, pfSense, and ROS.

The SBC without memory, storage, or wireless connectivity starts at $199. The barebone model with a metal enclosure is priced at $249. Two models with 8GB RAM/256GB SSD and 16GB/512GB configurations, along with the Intel AX210NGW WiFi 6E/BT 5.2 module, are available for $299 and $349, respectively. Power supply is not included with any of the options.
