@xiangpeng.systems shared a great post about system researchers. I wrote a comment on it and would like to share some thoughts here and offer complementary ideas.

In short: build paper with open source.

With @andrewlamb1111.bsky.social 's help, I assisted the Arrow Rust community in releasing Arrow Rust 54.2.1 within six hours.

I shared what I learned during this process, which I believe could benefit other ASF projects in handling similar cases.

The AWS S3 SDK breaks its compatible services by enforcing integrity checksums. This reminds me of another key advantage of Apache OpenDAL: it's not controlled by any storage vendor.

Don't bother building dsdgen—just use @duckdb.org instead.

Personal software has been trending recently.

I enjoyed reading @leerob.com's "personal software" and @edmarferreira.bsky.social 's "selfish software". Hope you enjoy them too!

"Cloud virtualization: Red Hat, AWS Firecracker, and Ubicloud internals" provides a great conclusion to cloud virtualization in the 2020s.

Reading this post will give you a good understanding of the current state of cloud virtualization. Highly recommended.
