Intel’s Redwood Cove: Baby Steps are Still Steps

Intel’s Meteor Lake chip signaled a change in Intel’s mobile strategy, moving away from the monolithic designs that had characterized Intel’s client designs for more than a decade.

啊，多么美好的日子啊
幸福美满的今天也好吧
输给梦想的今天也罢了
啊，我还没有放弃挣扎
在狭窄又宽广的世界里
歌唱着奇迹

Arch Linux: Recent news updates
Manual intervention for pacman 7.0.0 and local repositories required

With the release of version 7.0.0 pacman has added support for downloading packages as a separate user with dropped privileges.

For users with local repos however this might imply that the download user does not have access to the files in question, which can be fixed by assigning the files and folder to the alpm group and ensuring the executable bit (+x) is set on the folders in question.

$ chown :alpm -R /path/to/local/repo

Remember to merge the .pacnew files to apply the new default.

Pacman also introduced a change to improve checksum stability for git repos that utilize .gitattributes files. This might require a one-time checksum change for PKGBUILDs that use git sources.
