openrsync

在「openrsync imported into the tree」這邊看到 openrsync 專案進入到 OpenBSD 的 source tree 內。

rsync 是使用 GPLv3 授權,這個授權剛出來的時候,幾個比較大的 BSD 的團隊都有找律師研究過,最後都是做出不要把 GPLv3 的軟體放進 source tree 的建議,但 rsync 算是很好用的工具 (尤其是在效率上)。

看起來 openrsync 這個專案主要的目的就是重新實做出 ISC license 版本的 rsync:

This is an implementation of rsync with a BSD (ISC) license. It's compatible with a modern rsync (3.1.3 is used for testing, but any supporting protocol 27 will do), but accepts only a subset of rsync's command-line arguments.

然後目前只有設計在 OpenBSD 上跑,其他平台可能需要花些時間 porting 修正相容性:

At this time, openrsync runs only on OpenBSD. If you want to port to your system (e.g. Linux, FreeBSD), read the Portability section first.

GitHub 上的 Git repository 只是個 mirror,真正在管理程式碼的部份還是使用 CVS

This repository is a read-only mirror of a private CVS repository. I use it for issues and pull requests. Please do not make feature requests: I will simply close out the issue.

CC BY-SA 4.0 的素材可用於 GPLv3 的作品裡

Creative Commons 在經過幾個月的分析後,認為 CC BY-SA 4.0 相容於 GPLv3 的要求:「CC BY-SA 4.0 now one-way compatible with GPLv3」。

In January we officially opened a public consultation (blog post) on CC BY-SA 4.0 unilateral compatibility with GPLv3, in accordance with our ShareAlike compatibility process and criteria. Following additional months of detailed analysis, discussion and deliberation with the Free Software Foundation and other stakeholders, we are very pleased to announce that we have added a declaration of one-way compatibility from CC BY-SA 4.0 to GPLv3 to our compatible licenses page!

也就是說,CC BY-SA 4.0 的素材可以放到 GPLv3 的作品裡使用並且散佈。不過要注意的是,這是 CC 的分析,而不是法院判決的結果...
