Founder @ ParaQuery (YC P25) | Data processing for the GPU era. https://xitter.cf/t.co/tWz7U2i0pl Dilettante of FP, PL, physics, quantum computing, and trolling AI with math.

Joined June 2011
My favorite talk from Scala Days 2026 was about baking refinement types right into the compiler. Unlike libraries like Iron or Refined, it adds a built-in solver that verifies logic and math across multiple variables at compile time with zero runtime cost. Moving from simple checks to full verification is how Scala's type system should evolve to constrain LLMs - AI code won't compile unless the math holds up.

While I was dreaming today, a solution to proper agents sandboxing was revealed to me. Let’s put their sandbox inside another sandbox. This way when the agents escape the first sandbox, they think they’re free and stop trying.

Introducing Blender Bench v1 (BBv1): a benchmark for frontier LLMs on 20 realistic 3D production workflows including animation, modeling, rigging, cloth & surfacing. GPT-6 Astra leads overall; Claude Opus 5.5 wins modeling & cloth simulation.

Fun programming history fact: @akka_io_ was Lightbend was Typesafe before it dropped Scala and Play and focused on Akka. Lightbend was a name that replaced Typesafe because they thought it's a bad name for marketing. And now the hottest thing is @typesafeai. And I built TypeSec: pair.rs/typesec.

A bunch of new followers here so I figured I'd reintroduce myself :) Hi, I'm Marco. 1. I was Born and raised on Earth and I don't know which words to capitalize. Both of my parents are teachers so you think I would have learned this, but I am kinda dyslexic. 2. Before I did startups I was broke. After I did startups I am still broke. 3. I have three degrees in computer science and applied mathematics 4. I run sometimes when I feel fat 5. I love backcountry skiing because I am too poor to ski at the resorts. 6. When tech moats started shrinking I moved the SF, created a tech startup and then immediately failed. I have not slept much since. DM me if you're in town and want to meet up !!

I joined @nvidia nine years ago today, against the advice of a colleague who said their comp was below market. But I really believed in the mission and the people, so I went. I met @__simt__, Michael Garland, and Jared Hoberock on the C++ committee. I thought they were the smartest people there. I worked at @BerkeleyLab on concurrent and parallel programming paradigms, mostly for SIMD. @__simt__ convinced me that SIMT was a superior model for parallelism. He sold me on a revolutionary new GPU architecture where threads would independently scheduled: Volta, the basis of all modern GPUs. I asked him three times to find me a place at @nvidia. The first two times, he wasn't sure where to place me or if I'd like it. The third time, he had me come in to talk to Chris Lamb (now VP of CUDA). We chatted for two hours and he outlined the role he believed modern C++ would play in CUDA. I came back for an 8 round interview panel. All of the questions were answered with std::atomic. No one was sure what I would be working on. I, a modern C++ person, was placed in the CUDA driver org, which was written almost entirely in C. On my first day, my manager told me I'd be responsible for Thrust and CUB, @nvidia's first two open source libraries. No one had worked on them for a while and there was no product manager. I'd have to do it all. I put together a roadmap and got the libraries back on GitHub. I started sending status updates from CCCL, the CUDA Core Compute Libraries team, which did not exist. Eventually, they let me hire three people to fill out the team. We built libcu++ and abstractions for all the quirky new features being added to our chips to support these AI workloads that seemed to be growing in importance rapidly. After a few years I was asked switch orgs and guide the roadmap for our HPC C++ compiler. Programming languages and models quickly became my role, from stdpar to CUDA-Q to CUDA Python to CUDA Tile to autoresearch. What a ride it's been!

Data doesn’t exist in isolation. Customers connect to orders, products connect to sales, and teams connect to the processes they manage. In data warehousing, what is an "ontology" used for? A) Mapping how different parts of your business connect to each other B) Encrypting and storing sensitive credentials C) Transforming raw data into a new format D) Ingesting files from external sources

Episode 2 of WhoDB Who is here. 🚀 Here's how the WhoDB platform works: data gets ingested through sources, files, and datasets, transformed, and stored as structured entities with visible relationships. On top of that, you can build applications backed by business functions, plug in your own AI providers, and use the WhoDB Agent to chat with your data directly. No technical background required.

Probably the biggest startup announcement of the year (decade?) in terms of the calibre of founders. If I had to name the top 10 engineers currently or previously at Google in terms of impact it would be the two cofounders (Larry and Sergey) and all 4 of these folks:
Announcing Discovery Loop! I am very excited to announce that, along with my longtime friends and collaborators @Sanjay_Ghemawat, @OriolVinyalsML and @quocleix, we are founding Discovery Loop (@DiscoLoopAI), a Public Benefit Corporation whose mission is to automate machine learning, science, and engineering to accelerate discoveries and progress. The four of us have worked together for 14 to 30 years, and have helped build some of the world’s most used products, infrastructure and AI models, and we’re excited to turn our attention to this ambitious endeavor. ♾ Learn more at: discoveryloop.com

The people who still read won't just be better informed. They'll be (with a couple exceptions) the only ones who can think well. You can't think well without writing well, and you can't write well without reading well.

Clidey is now part of the NVIDIA Inception Program. NVIDIA Inception supports early-stage companies pushing the boundaries of AI and data infrastructure. Being part of it means access to better resources, technology, and a network of companies building at the edge of what's possible. We're just getting started.

We’ve spent years watching teams accumulate more data while decisions remain slow. Today, we’re launching WhoDB. Every company faces the same intelligence problem: data exists everywhere, but decision context is fragmented across databases, warehouses, SaaS tools, spreadsheets, Slack, and dashboards. Today, we’re launching WhoDB: an open-core, AI-native decision platform designed to help teams move from fragmented data to faster, better decisions. WhoDB connects to your sources, creates the ETL paths, builds an ontology of your business, respects governance, and gives teams apps they can use to act on the data. Open-core Palantir for everyone.

Getting your apps to communicate is a massive bottleneck. WhoDB links your existing systems so they share data automatically. You keep your current stack, and we handle the connections behind the scenes.

1/ Today we're launching Cua-Bench with @SnorkelAI: a benchmark for computer-use agents on professional software, open for any model to run. The benchmark covers 25 expert-authored KiCad tasks, and the best frontier model we tested cleared only 6 of them.
