Nutmeg 0.1.0: graph algorithms where the data already is

Grust's graph kernels inside Sail's Spark Connect server: stage a graph from a DataFrame, call an algorithm, get a DataFrame back.

Grust Langoustine: narrower graphs, cheaper accounting, and scores you can ask for in f32

Grust's latest backend-neutral property-graph release.

What one PageRank sweep costs: five implementations on one host

What one sweep of one PageRank kernel costs across five implementations on one host, with every distance carrying its margin.

Grust Mysid twenty-three graph algorithms, and the properties they needed

Grust's latest backend-neutral property-graph release.

Graph algorithms, full paths, and the work a benchmark must count

A full-path graph algorithm benchmark over 2.147 billion path entries: an explicit output contract, three rounds of optimization, two regressions and one correctness bug.

Grust Brine: admission follows Arrow data

Grust Brine retains execution admission through shared Arrow buffers and graph algorithm results.

Graph stores under strain: Rust in process matches Neo4j's reach, beats it on speed, and closes most of the memory gap

Rust in process now matches Neo4j's reach at 117 million edges and beats it on speed in every same-machine pair; Neo4j's memory lead is down to 10 to 40%. What 352 runs in 33 verified bundles show.

Announcing Fihrist

Fihrist brings versioned enterprise table contracts and governed agent reads to the QueryGraph stack.

Eigen Hacks: what one threshold was hiding

Eigen Hacks is Eigen Times pointed at twenty years of Hacker News. The corpus, the fit and the site went up in a day; the interesting part was discovering that the paper was quietly nonsense—one clustering threshold inherited from newspapers merged half of every day into a single story—and what coun

The First Pair Emacs Reader

How a story from Mark Liberman about learning Spanish in Emacs became a parallel-text reader in GNU Info with a dictionary under every word, and why we forked iSH as 1Unix to make an iPhone terminal touchable.

Graph Books

As a lifelong fan of Dante and Italy, I tried to learn Italian many times to read the Commedia, and it never stuck. Have to go live in Italy for that. The closest I ever got was to become a director of Open-Source Science at IBM, reporting to Anthony

Eigen Times: a newspaper in the eigenbasis of the news

A newspaper that prints each day as coordinates in the eigenbasis of a quarter-century of news—recurring archetypes, the daily decomposition, and what is different this time—built two ways and compared.

Rust AI Amsterdam, Sail at Adyen

The first Rust AI Europe meetup is hosted by Adyen and LakeSail in Amsterdam on September 9, ahead of the PyData Amsterdam conference. Reserve your seat ASAP, we'll be sold out: https://luma.com/ai-f2z9. LakeSail has rebuilt the entire Spark ecosystem in Rust, including Delta Lake

Gruff Rag, or what Context Engineering actually is

Meet Gruff Rag — a developer hero debunking AI hype around “GraphRAG” , “Context Engineering,” and “Semantic Layer.” If anything, Gruff Rag is more real than GraphRAG. As the former AI Community Architect, I’ve spent an year and a half connecting OSS AI communities in graph space, eliciting patterns that emerging

The Web Has Margins Again: W3C Annotations for the Developer Community Graph

How devreal.ai links Functional TV metadata and external videos through portable W3C Web Annotations.

DNSSEC in the spirit of tinydns

August 2026 — rgbdns 0.6.3 DNSSEC can look like an invitation to build a control plane: a key database, a signing service, an RPC protocol, a stateful rollover controller, and an online authority that knows too much. That would be one way to add cryptographic signatures to DNS. It

Interoperable Cloud Sevrices at First Pair

chief.sc is both in Ghost and Suffix

For almost a decade, I've used the chief.sc domain in bit,ly, as a custom domain for my short URLs, typically Medium posts on my own publication chiefscientist.org. At some point bit.ly caught up to my free account with a custom domain, and I could

All 12 Rust AI Begins recordings are live

The shortest, deepest technical conference about Rust in AI: ten systems talks compressed into one three-and-a-half-hour San Francisco meetup. Rust AI Begins was built as a technical sprint. On July 27, 2026, builders gathered at AWS Builder Loft in San Francisco to show where Rust is

DevReal is live: the graph behind developer culture

x 7,233 people, events, talks, recordings, organizations, projects, topics, and photo albums—connected by 14,246 relationships. A conference page tells you what happened once. A community graph can tell you who was there, what they built, where the recording lives, which company they represented at the time, who

The Adversarial Cognition Trilogy: one boundary, attacked at three layers

What began as a single benchmark for an AI's memory is now three, and the reason is worth stating plainly, because we did not set out to build a suite. We set out to attack one boundary — the governed boundary that decides who may reveal or change this,

MARCIANA-ADVERSARIAL-v1: benchmarking cognition under attack

MARCIANA-ADVERSARIAL-v1 is now a standalone benchmark with a site at adversari.al, a FirstPair book, six systems compared, and an open call for contributions — plus why the boundary is unforgeable, not just careful.
