Major insight from @tnachen & @robby_mtf convo w/ @floxdevelopment CPO @jambay: The biggest opps aren't always building something new - they're making something powerful usable💪 Nix has existed for 20+ years & Flox is making the notoriously complex tech simple Check it out👇

Flox powers @resolveai's dev environments. The team triaging production incidents for the world’s biggest companies can now run the same setup locally, in CI, and in prod. Learn more here: buff.ly/LPpmyrO

fellow.ai/ supports distributed teams across 100+ countries. But growth exposed familiar problems: ⚠️ Inconsistent dev environments ⚠️ “Works on my machine” failures ⚠️ Slower onboarding + rising release risk With Flox, Fellow standardized reproducible environments across the SDLC without changing how engineers work. Result: faster onboarding, higher velocity, fewer fire drills, and a more reliable path from dev → CI → prod. “Flox gives us a dependable foundation so we can move fast with tight feedback loops.” — Samuel Cormier-Iijima, CTO & Co-Founder Case study in comments.

CVE remediation is a dependency-graph problem. Scanning attempts to infer from built artifacts. Flox/Nix derive artifacts + runtimes from the causal dependency graph. Remediation = dbms lookup + declarative edit: identify artifacts/envs, pin a replacement ref, promote. Read more in the comments!

Saw a tweet about the lunch @cognition, so I dropped a comment asking if there was a kosher option. Two days later, Max Martin from Cognition AI’s NYC office reached out and invited me in for a kosher lunch and a tefillin wrap with the Jewish team. We ended up getting a full minyan 10 guys putting on tefillin together. What started as a comment turned into something really meaningful. Pictures below.
One of the most underrated perks of @cognition is the office chef

☃️🏆The York Lions are U SPORTS men’s soccer champions for the first time since 2015. Christian Zeppieri scored a 116th minute PK to win it after a very light handball was called. Wild weather called for the perfect knee slide.

As the hostages come home, I have tears in my eyes As the War winds down, I'm beaming with pride For the last decade or so it has oftentimes felt like the American empire is in decline But today it feels like America is rising again, and lifting its friends along with it 🇺🇸

Back in 2021, I wrote down the set of problems that annoy me the most. #1: Local dev environments are brittle. I had worked at enough companies that shoehorned docker-compose into trying to solve this, and while it does improve things, it also sucks in many ways. Even back then Nix looked like it might be the solution for this—but it has an incredibly steep learning curve. At @Shopify we've invested a bunch of effort into building a tool around Nix called `dev` that makes this simpler. Now, @floxdevelopment is finally solving this for everyone! 😍 Flox is a language-agnostic package and environment manager based on Nix with a great developer experience. All you need to do to get set up locally is: $ flox activate and you're good to 🤯 With relatively simple configuration, it allows you to: · Define everything your environment needs—packages, tools, environment variables, and services—in one manifest. · Switch between environments easily, share them with your team, and keep everything in version control. · Use the same setup across macOS and Linux, on both x86 and Arm. It's absolutely killer. I'm a huge fan. Every codebase that is more complex than a single package.json should use this. That's why I'm also thrilled to have invested in their Series B. 👇

Super excited to see @floxdevelopment keep expanding where they’re taking Nix.
We’re thrilled to share that Flox, the Nix Foundation, and @NVIDIA are teaming up to make it easier for teams working with NVIDIA’s CUDA GPU compute framework to build and ship CUDA-accelerated stacks.🎉 This partnership is about supporting developers with a more seamless experience and strengthening CUDA’s value across the wider ecosystem. It’s a major step forward for anyone building AI, ML, HPC, and GPU-accelerated applications as teams can now build and deploy portable CUDA runtimes that just work, anytime and anywhere. ✅ The NVIDIA CUDA Toolkit will soon be available as a pre-built package in the Flox Catalog. ✅ This means CUDA-enabled PyTorch, Tensorflow, and OpenCV will also be available, along with… thousands of pre-built CUDA-accelerated packages! ✅ Users across the Nix and Flox ecosystems can create reproducible CUDA-accelerated environments for AI, ML, HPC, data science, and other use cases.

A big day for @floxdevelopment. Flox Catalog (!!)
We are excited to announce Flox 1.5! With this significant release, users can build packages and publish them into the Flox Catalog for the first time. New subcommands have been added - build and publish - and there is a new section in the manifest to define package outputs. See buff.ly/PbGR2VH for download links and full release notes.

So thrilled for @jsarihan @Ryanjdaniels and the entire Crosby team. Crosby is the API for human agreement that allows companies to execute faster:
Today we’re introducing Crosby, a hybrid AI law firm that helps rapidly growing businesses execute faster. Contracts are connection points. They allow companies to transact with one another and create economic growth. But while every aspect of business has sped up, the way we negotiate contracts hasn’t changed in 50 years. Crosby is building the API for human agreement. We combine the speed and intelligence of AI with the safety of lawyers-in-the-loop to review contracts in under an hour. Since quietly launching in January, we’ve reviewed over 1,000 MSAs, DPAs and NDAs for some of the fastest growing companies in history, including @cursor_ai, @clay_gtm, and @unifygtm. Speed to execution is our north star, and today our median review time is 58 minutes. GTM teams call Crosby a secret weapon to close deals 80% faster. We’re just getting started. Today, we’re also excited to share that we’ve raised $5.8m from @sequoia and @BainCapVC, as well as the founders of Ramp, Instacart, Flatiron Health, and others. Crosby is a small, talent-dense team, combining lawyers from Harvard, Stanford, and Columbia Law with engineers from Ramp, Vanta, Meta, and Google. Every engineer on our team today is a former founder. We work in person in New York City. If our mission resonates with you, we are looking for technologists, legal experts, and former founders to join us. For high-growth companies looking to execute faster, we’ve opened up Early Access. Sign up on our website and we’ll be in touch.
