Total comment counts : 12
Summary
The openSUSE project has released the second release candidate (RC2) of its Aeon Desktop, which aims to provide automated system updates using snapshots that can be applied atomically. Aeon uses transactional-update and Btrfs subvolumes to create and update system snapshots, allowing users to roll back if needed. The distribution also incorporates application-containerization technology like Flatpak, Podman, or Snap to separate user-installed software from system software. Aeon comes with a minimal set of installed software, with additional applications needing to be installed separately.

SpaceX has applied for permission to launch a constellation of almost 30,000 satellites through Tonga’s authorities, and some speculate that this move is an attempt to bypass scrutiny from the FCC. The Tongan Space Program has reserved numerous spots for satellites but has very limited resources and has only launched one satellite so far.
5. Hardware FPGA DPS-8M Mainframe and FNP Project
Total comment counts : 4
Summary
The article announces a long-term project to implement the DPS-8/M mainframe architecture using FPGAs. The project is led by Dean S. Anderson, who has experience working with Honeywell Series-60/Level-66 mainframes. Anderson plans to implement the complete DPS-8/M architecture, but initially focuses on the Front-end Network Processor (FNP) component known as the DN355. Charles Anthony, a programmer who worked on the DPS8M Simulator, assists in completing the FNP simulation in software. However, it is discovered that the Multics operating system only supports later models of the FNP. Adjustments are made to target these models, and an FPGA is selected that includes an ARM CPU core. The goal is to gradually replace sections of the software code with Verilog FPGA implementations.

Top 1 Comment Summary
The author of the article expresses their dislike for auto-generated commit logs as they tend to have excessive noise. They believe that changelogs should be for users to read. They have a program that generates the initial draft of the rclone changelog from the first line of each git commit. They encourage contributors to make their commit message a user-friendly description for the changelog. However, they still spend about an hour editing the auto-generated changelog, removing noise, condensing entries, reorganizing, and improving clarity where necessary. They prioritize important information and aim to keep the changelog brief since users do not want to spend hours reading it. They also mention the difficulty of enforcing a specific commit message format, and therefore, find it necessary to manually edit the changelog. While it would be ideal to avoid spending so much time on editing the changelog, they believe it is their responsibility to provide a well-crafted changelog for the users and cannot delegate that task to a program.
Top 2 Comment Summary
The article argues that using commit log diffs as changelogs is not a good idea because commit logs contain noise such as merge commits, commits with obscure titles, and documentation changes. The purpose of a commit is to document a step in the evolution of the source code, while a changelog entry is meant to document noteworthy differences and communicate them clearly to end users.
