About the fatal perils and traps of many modern tools that handle "shell commands" as passed through `system(3)` or `sh -c`. Or, how by the end of 2020, we still haven't given up on shell's equivalent "SQL building", or how shell's equivalent "SQL injection" still thrives in our engineering world... Plus a `glibc`…
Perhaps the most often repeated complaint about Rust is its slow feedback loop and long compilation times. I hear about it all the time; in Rust podcasts, blog posts, surveys, conference talks or offline discussions. I also regularly complain about it, being a Rust user myself!
A detective story with a silly ending
An introduction to a new post series covering debugger basics.
Discovering a JDK Race Condition, and Debugging it in 30 Minutes with Fray I’ve been adding more integration tests for Fray recently. To ensure Fray can handle different scenarios, I wrote many creative test cases. Many of them passed as expected, while some failures led to epic fixes in Fray. Then something…
The power of Zig's comptime code execution
In this blogpost I will step by step show you how to implement a highly efficient transpose kernel for the Hopper architecture using Mojo. The best kernel a...
Learn how we tracked a performance bottleneck to a 15-year-old Git function and fixed it, leading to enhanced efficiency that supports more robust backup strategies and can reduce risk.
Recently I’ve been working on a pretty big rust project and to my surprise Icouldn’t get tests to work properly.
TigerBeetle is an Online Transactional Processing (OLTP) database built for double-entry accounting with a strong emphasis on safety and speed. It builds on the Viewstamped Replication (VR) consensus protocol to offer Strong Serializable consistency. Unlike general-purpose databases, TigerBeetle stores only accounts…
Machine code isn't scary. If you can make sure your JSON conforms to a JSON schema, you can write machine code.
[New to Gemini? Have a look at my Gemini FAQ.] This article was bi-posted to Gemini and the Web; Gemini version is here: gemini://gemini.circumlunar.space/users/kraileth/neunix/2025/installing_bsd_…
Why is DeepSeek-V3 supposedly fast and cheap to serve at scale, but too slow and expensive to run locally? Why are some AI models slow to respond but fast once…
Introducing oniux: Kernel-level Tor isolation for any Linux app. This torsocks alternative uses namespaces to isolate Linux applications over the Tor network and eliminate data leaks.
One of my more frequent rants, both online and in person, is the danger posed by the "fast-math" compiler flag. While these rants may elicit resigned acknowledgment from those who already understand the dangers involved, they do little to help those who don't. So given the remarkable paucity of writing on the topic…
Exponential backoff with jitter is de rigeur for making service calls. This code, or something like it, probably looks really familiar: func do(ctx context.Context) error { const ( maxAttempts = 10 baseDelay = 1 * time.Second maxDelay = 60 * time.Second ) delay := baseDelay for attempt := range maxAttempts { err :=…
We have some very fast AI-generated kernels in pure CUDA-C without using libraries and DSLs such as CUTLASS and Triton. They are performing close to or in some cases even beating the standard expert-optimized production kernels shipped in PyTorch. Some of our highlighted results:
PoW is gone 🦀🦀
I built a simple web crawler using good old platform threads. It was just a multithreaded crawler, nothing fancy. But then, curiosity…
Databricks offers a unified platform for data, analytics and AI. Build better AI with a data-centric approach. Simplify ETL, data warehousing, governance and AI on the Data + AI Platform.
They're Mario Bros. for the NES, apparently.
This is going to be a long post, but I hope you get value out of it. This wasn’t an easy topic to tackle but it was definitely worthwhile!

AWS Senior Principal Engineers, Niko Matsakis and Marc Bowes, take us inside Aurora DSQL's development: scaling write operations without two-phase commit, overcoming garbage collection hurdles, and embracing Rust for both data and control planes.
At 7AM (UTC) on Tuesday May 20th 2025 a BGP message was propagated that triggered surprising (to many) behaviours with two major BGP implementations that are often used for carrying internet traffic.
My little corner of the web for sharing wherever my interests take me.

The bizarre story of how taking flash photos could instantly crash the Raspberry Pi 2, the community detective work that solved it, and why this strange bug revealed fundamental flaws in modern chip design.
