For everyone interested in data infra, want to get a quick sense of how big data works, how data systems are designed, and what the tradeoffs are, start with this share from @xiangpeng.systems, really nice intro! intro-data-system.xiangpeng.systems

Thank you for the kind words!

Rust is not “Other” in linux anymore 🤪

@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. xuanwo.io/links/2025/0...

I shared a post about mcp-server-opendal along with a simple explanation of what the Model Context Protocol is. Post: xuanwo.io/links/2025/0... Repo: github.com/Xuanwo/mcp-s...

opendal.apache.org/blog/2025/03... Apache OpenDAL 2025 Roadmap: Perfecting Production Adoption

Archlinux announced that they will remove the deprecated repository and now it effected. Please go check your /etc/pacman.conf and remove the section that is deprecated. xuanwo.io/links/2025/0...

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. xuanwo.io/links/2025/0...

Happy to read zlib-rs is faster than C from @trifectatech.bsky.social. I read that post and took some notes on SIMD instructions and DFA jump threading. Feel free to check them out! xuanwo.io/links/2025/0...

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. xuanwo.io/links/2025/0...

Chris Riccomini (@chris.blue) shares his thoughts on Open Source foundations: Apache, CNCF, Commonhaus. He also explains why Commonhaus is a better fit for SlateDB cnr.sh/posts/compar...

I am happy to announce the release of BackON v1.4.0. BackON has been used by 1.1k projects on github, and been downloaded for 20k times per day. Really nice! xuanwo.io/links/2025/0...

Really appreciate @github.com and @glich.stream 's help with OpenDAL's GHAC service migration. xuanwo.io/links/2025/0...

duckdb is the best TPC data generator! Don't bother building dsdgen—just use @duckdb.org instead. xuanwo.io/links/2025/0...

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! xuanwo.io/links/2025/0...

"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. xuanwo.io/links/2025/0...

I decided to follow @simonwillison.net's approach to creating a link blog, where I can share interesting links I find on the internet along with my own comments and thoughts about them. xuanwo.io/links/2025/0...

My 2024 review will answer 40 questions to myself😜 xuanwo.io/2025/01-2024...

Happy New Year!

Maybe we can build a tool based on opendal to find the best object storage key pattern for given storage services? github.com/apache/opend...

#TIL: new bug from Ceph RADOS. Invalid etag value in complete multipart uploads response:

I haven't found a practical use for the infinite spinning wheel, but the act of spinning it makes me happy. I could spin it all day long!

Just bought a new Logi MX Master 3X. Really love it!

Great, I'm now a contributor to wasmtime!

The next version of OpenDAL will be "v0.51.1 - Look, a New Day Has Begun," a famous line from Cats Musical. Hoping you all find happiness in the coming new year ❤️ github.com/apache/opend...

Fewer commits than last year, but there was more collaboration within the community. The happiest moment for me this year was being elected as an iceberg committer and starting iceberg-rust together with liurenjie1024. Next year will bring more RBIR projects—let's keep moving!

New Post: A letter to open-source maintainers Hoping maintainers can find happiness in open source. xuanwo.io/2024/10-a-le...

The things that inspire me to keep contributing to OpenDAL. Thank you, kind strangers!

Hello, bluesky. The recording of my CMU-DB's Building Blocks Seminar Talk about OpenDAL is online now. If you have any questions about OpenDAL or are looking for collaboration, feel free to DM me! www.youtube.com/watch?v=eVMI...

I'm happy to become the cache of this API. Please grant me the write permission.

What happened to SPDK? It doesn't seem to have been active since 2021. In fact, the entire trend of kernel bypass seems to have faded as io_uring and BPF have matured. Is it just my imagination?

Hi, @bohutang.bsky.social , the cofounder of @databend.com is here😍

Hello everyone, the first Iceberg #Rust Community Sync will happen at 28th Nov (today!) at 23:00 UTC+8. Welcome to join us! docs.google.com/document/d/1...

When something like Redis is so widely used that it becomes an informal standard, how should the open-source community engage with the original author? This discussion is worth joining, and I look forward to your comments. Thank @mitsuhiko.at for setting up the context. github.com/redis-rs/red...

Looking forward to!

Rust Edition 2024 scheduled to be released on February 20, 2025. Nice! github.com/rust-lang/ru...

Wow, just find @andrewlamb1111.bsky.social is on bluesky, happy to see! Follow him if you are interested in rust, database, arrow and datafusion 😍

backon is a lib that makes retry like a built-in feature provided by #Rust. I'm excited to announce the release of v1.3.0, which includes several quality-of-life improvements. Enjoy! github.com/Xuanwo/backo...

Has AWS S3 changed its leadership or something? This year, S3 has undergone so many changes that it seems like they've undone progress from the past 10 years. - Deprecated SelectObject - Added AppendObject (directory bucket only) - Introduced PutObject if none exist

That's huge. Created an OpenDAL issue for it: github.com/apache/opend...
