Big new blogpost! My guide to data visualization, which includes a very long table of contents, tons of charts, and more. --> Why data visualization matters and how to make charts more effective, clear, transparent, and sometimes, beautiful. www.scientificdiscovery.dev/p/salonis-gu...

First of many blog posts about the Rust vision doc process: blog.rust-lang.org/2025/12/03/l...

this fall I worked with the core Git folks on writing an official data model for Git and it just got merged! I learned a few new things from writing it. github.com/git/git/blob...

Video of the One Billion Row Challenge stream is now up at youtu.be/tCY7p6dVAGE! We got down to 1.2s without any external dependencies, and it was a fun journey down lots of performance rabbit holes (only some of which panned out 😅). It is over 10h, but hopefully the chapters in the video help!

Sometimes an interface is so ubiquitous that performance limitations inherent to its design are just accepted. This has been our experience with Parquet. We switched to Vortex which aligned much better with our needs and saw a 70% performance improvement across the board. Read more below 👇

it's such a joy to build software exclusively for yourself definitely a form of self-care

PSA!!

At long last, @chris.blue and I have submitted the final manuscript of Designing Data-Intensive Applications, second edition, to the publisher. There is always more that could be improved but at some point we just have to call it done. Now it goes into production; probably shipping in ~4 months.

@eurorust.eu 2025 is beginning! So excited about getting to attend live online! 🦀🦀 The two tracks are pretty tough to choose among, let's see if we can manage to sneak in the replays during the breaks...

Antithesis has put up recordings from last few DC Systems, including this gem of a talk on Controlled Concurrency Testing for JVM Programs by Rohan Padhye! 🙌🏼🙌🏼 Check it out! www.youtube.com/watch?v=AX6P... Fray, the concurrency testing toolkit for the JVM: github.com/cmu-pasta/fray

Greetings from #sd25! It's a two-day single-track conference hosted by @tigerbeetle.com. I'll be aiming to liveskeet as many of the talks as I can. Super excited to be here! systemsdistributed.com

We’re thrilled to reveal our 2025 #rustconf program! 👀 this thread for the full list or visit rustconf.com/schedule

ed is the standard editor (unix), but apparently edit is the standard editor (windows) github.com/microsoft/edit in #rustlang!

We are opening up the @oxide.computer Discord to more than just recording Oxide and Friends, and now have some general discussion channels, as well as some user channels for our open source projects discord.gg/FRwjhBaH

Once I started with my first few major Rust projects, I found Clippy could be a great tutor/reviewer! So I spent an entire weekend going through *every* Clippy lint, curating the greatest-hits! 💿🦀 Feel free to drop them in your own Cargo.toml: gist.github.com/aksh1618/f45...

I had some free time recently – so decided to complete CodeCrafters' "Build Your Own Kafka" challenge. When I started this challenge at the start of this year, I had three goals: 1. Get more hands-on experience with Rust 2. Get to know Kafka internal better 3. Complete the challenge

Let chains are one of my favorite Swift features. Glad to see them stabilized in #rustlang github.com/rust-lang/ru...

“KIP-1150 introduces Diskless Kafka topics that write directly to S3 instead of replicating between brokers.” “Even using the expensive S3 Express (which a week ago lowered its prices by more than 50%) still saves 73% compared to traditional Apache Kafka.” /ht @ananthdurai.bsky.social

Distributed systems built on object storage all have one common problem: removing files that have been logically deleted, either due to data expiry or compaction. What's the solution? We'll give a hint: it's not bucket policies or synchronous deletion 👉 buff.ly/XAB6mOi

I enjoyed @alexmillerdb.bsky.social's "Decomposing Transaction Systems" blog so much I had to write up how I'd decompose Aurora DSQL in a new blog post: brooker.co.za/blog/2025/04...

Aaaand we're up and running on @railway.com with #zero2prod in #rustlang !! 🚀🚀🚀

one of my favorite ways to explain the value of RSC is to frame it as a React version of the BFF (“backend for frontend”) pattern. it doesn’t have anything to do with “server rendering”, SEO, or such. i think of it more as an alternative to (or a layer above) traditional JSON APIs. like BFF.

Monster SCALE summit by @scylladb.com is starting soon, hop in! #distributedsystems

Not my story but imho nothing will ever top gist.github.com/kemitchell/f...

hey quick #rustlang tip: do you have deeply nested modules? you can do this: mod foo { mod bar { mod baz; } } instead of putting 'mod bar;' in foo.rs and 'mod baz;' in bar.rs it's kinda nice to see the module tree in one place, imho

@hytradboi.bsky.social is starting in an hour, hop in! #distributedsystems

#rustlang 2024 is here! blog.rust-lang.org/2025/02/20/R...

Yandex released a new eBPF profiler. If you're into profiling, I highly recommend reading their announcement post. It covers a lot of background knowledge, and also introduces some cool new ideas such as capturing micro coredumps when a process gets killed! medium.com/yandex/yande...

been reading a lot of comments today about how people find man pages hard to read and it made me mad (why do they have to be so hard!) so I'm giving away 300 copies of Bite Size Command Line to folks for whom $12 is a lot of money! (with code BUYONEGIVEONE) wizardzines.com/zines/bite-s...

Recently discovered gq in vim and it has changed my life

Finally received my copy of @natedimeo.bsky.social's "The Memory Palace" after a looong wait! It's even more beautiful in person! 🩷💙

If Maven Central goes down, hell sets loose. I'd say MC is more important than the JDK these days. And that's because devs have *lots* of options on where to get a JDK from. But dependencies? Not really. Good luck building a private copy without Central, if you don't have one already when 💥 boom.

Having completed the book last year, I've started working on a real-world-y project in rust. Going to share things I encounter and learn here. Welcome to "Beyond the Book"! (This would be extra relevant for folks like me coming from languages like java) #rustlang

Completed my first reading of Designing Data-Intensive Applications by @martin.kleppmann.com just in time before 2024 wraps up! Wrote about my experience here: aksh.dev/book-review-... #ddia

What's one improvement you'd like to see in @obsidian.md in 2025?

Anyone looking for the best Kotlin-idiomatic Mongo DB bindings out there, and whose heart may have been broken by KMongo shutting down.... keep an eye on this project!

Dear friends, I'm rejoining Redis. It's a long story, so it deserved a blog post to explain all the details: antirez.com/news/144
