Simple AUTH mechanism now available for Luna. github.com/flowerinthen... #rust #cache #sql #duckdb #arrow

Fellow Rustaceans, Sharing a side project: Luna, an in-memory SQL "cache" server for object storage data. Main goals: - The "Redis" for OLAP, columnar SQL data, - Easy-to-deploy across different envs, but mostly for cloud setup, - Distributed/cluster support #rust github.com/flowerinthen...

Quite a good read about transactional systems. transactional.blog/blog/2025-de...

Max severity RCE flaw discovered in widely used Apache Parquet Discussion

Finished porting a memberlist library we heavily use at work from Go to #rustlang. It's my first attempt at writing a non-"hello world" Rust code and I'm loving it. github.com/flowerinthen...

I'm glad I came across this post about async/await in #rustlang. As one who complained a bit about it, having this context helps me understand it more and appreciate it. without.boats/blog/why-asy...

Been contemplating about what systems language to add to our company's stack for a while. I was considering either #ziglang or #rustlang. Ended up with #rustlang. flowerinthenight.com/blog/2025-03...

TIL that in #rustlang stable, if you use scopeguard's defer, rustfmt doesn't work on any code within the defer scope; only outside.

My feed is mostly politics now; rarely tech. So I don't check it as much anymore, nor do I engage as much. Sadly, the tech landscape is still pretty active over at the birdsite.

In #rustlang, calling async functions from sync code feels as "not quite right" as using unsafe.

Very interesting. DeepSeek team doing some really good work here. github.com/deepseek-ai/... Sophisticated setup though.

Some considerations to think about when integrating LLMs to internal workflows: flowerinthenight.com/blog/2025-02... #llm #genai #enterprise

Completed the porting of a Spanner-dependent cluster membership library to AWS. Changed from TrueTime to TimeSync via clock-bound. github.com/flowerinthen... #golang #aws #truetime

Been following Carbon’s progress for a while now. I appreciate this kind of explanation about its goals, non-goals, and nuances. herecomesthemoon.net/2025/02/carb... #carbon #carbonlang

New distributed systems protocol write-up! This write-up dives into the Virtual Consensus in Delos paper and why it makes sense as the default log replication protocol in the era of object storage and hybrid environments. jack-vanlightly.com/blog/2025/2/...

ROC compiler from #rust to #ziglang. I can sympathize to the main reason being slow build times. gist.github.com/rtfeldman/77...

@support.bsky.team Looks like there’s a problem with the site on Chrome iOS and Chrome Linux.

Love to see it.

#aws clockbound-based distributed locking (with #postresql as storage) looking good in testing. I would have preferred to not use CGO though. github.com/flowerinthen... #golang

10us.. not bad. Reading clock-bound timestamp from #golang via FFI+CGO.

I'm not a network expert or anything but it's also one of my interests. TIL about Homa, a new transport protocol for datacenters. Also learned about SRD, AWS' take on high speed networks for datacenters. Homa - people.csail.mit.edu/alizadeh/pap... SRD - assets.amazon.science/a6/34/41496f...

Took me hours to figure out why can I not SSH to EC2 anymore. Turns out, I've accumulated too many keys in my ~/.ssh/ already that Instance-Connect complained about "Too many authentication failures."

For #golang people, a Go client for github.com/aws/clock-bo... that uses the newer shared memory protocol (instead of the older socket protocol) is now available. github.com/flowerinthen... #aws #timesync #golang

If you're having problems updating google-cloud-go due to opentelemetry dependency issues, you can update now. 1) Remove the // indirect line from your go.mod 2) go get -u google.golang.org/grpc 3) go get -u cloud.google.com/go/storage github.com/googleapis/g... #golang

It looks like when using cloud-init in AWS ASGs, $HOME points to /, not /root?

Looking forward to this release. Zig 0.14.0 on Feb 17th. ziglang.org/news/what-to... #ziglang

Definitely.

Wrote something about how valuable source codes are. It explores Peter Naur’s theory building in programming. flowerinthenight.com/blog/2024-10...

"Going for a walk while C++ project is compiling." "Going for a walk. GitHub is down."

“AI will replace SWEs.” Wrong or not, if the companies’ top decision-makers believe and act on it, it will happen.

An “AI agent manager” agent that will give PIPs to underperforming agents for being inconsistent all the time.

For some strange reason it's somehow very satisfying to be able to do this. #rustlang

There’s a bit of a discussion going on about NVIDIA’s Project Digit on HN. Are there any other similar HW development out there for serving local LMs? This looks like a dev kit to me but might be feasible for onprem needs. news.ycombinator.com/item?id=4261... #nvidia #digit

Interesting study. Although there's PRs, Issues, contributors, last commit dates, etc, there's no denying that stars play a big role in evaluating repos in GitHub. arxiv.org/pdf/2412.13459

Hyper being dropped from #curl as an alternative HTTP backend. daniel.haxx.se/blog/2024/12... #rustlang

Azure's Resource Group idea is just fantastic, I wonder why this is not implemented in AWS nor GCP. "When you delete a resource group, all resources in the resource group are also deleted." learn.microsoft.com/en-us/azure/...

TIL. In C++, you can assign a value to a ternary operation result on the left side, like so: ((i < 5) ? a : b) = 77; Sets either a or b to 77, depending on the value of i.

Based on anecdotes, and my experience, I always thought that data-related migrations (e.g. databases) are more painful/chaotic than compute layer migrations, but it’s interesting to see how these play out mid/long-term. lethain.com/decompose-mo...

Slack’s memory usage could very well be the climate change graph.

I’ve worked with Bazel, CMake, Meson before but the conveniences brought about by cargo (or go build, or zig build) are undeniable. Standardized (opnionated) build/pkg management, formatting, etc, take away a lot of the unnecessary overhead in dev. #rustlang

Most of the time, we take for granted how fast Go’s compilation times are until you start compiling Rust or Zig code (or C++ for that matter).

I read this paper while researching disaggregated storage. It came out 15 years ago, in 2008. S3 had launched in 2006. This paper was way ahead of its time, with lots of interesting ideas for today's cloud computing.

TIL. As someone who uses cmdline all the time, this is fun. github.com/chubin/wttr.in

The fourth and last in my series of blog posts on our new Aurora DSQL database is up! This time, we're looking at what happens during network partitions, and how we preserve consistency, availability, and durability. Check it out: brooker.co.za/blog/2024/12...

I wonder if Google/GCP would ever expose an API for TrueTime now that we have access to AWS’ Time Sync Service.
