I can’t believe they invented irl excalidraw. What is this technology.
How we deploy multi-trillion parameter models at scale Today, let's break down the math for how @cerebras: 1. Fits the full model into on-chip memory 2. Maps the model across multiple chips 3. Handles a high # of concurrent requests

all technical work is becoming evals. your primary job as an engineer is now building loops that make coding agents effective maintainers of the systems you own. models are immensely capable - given clear instructions, the right environment, and a way to verify their work, agents can complete open-ended, long-running tasks. if you still think coding agents are shipping “slop”, it simply means one of these three things is missing. if you build product, you might need to restructure your codebase and give your agents fast, high-fidelity ways to test changes. if you’re a researcher, you might spend most of your time building pipelines for data synthesis and environment construction - experiments are the bottleneck, not ideas. the art is translating the real-world problem into the right eval: will the agent understand your exact criteria for when a task is sufficiently complete? and when the frontier shifts, do these criteria change? every engineer is an AI engineer now. in the long run, the ones who build the machine that builds the machine will be most effective. of course, the best will adapt. but if you’re not actively thinking about how to make agents better at your work, or you’re relying on other people to do it for you, you’re probably ngmi.

The only impressive thing left to do in software is building a product that feels great to use. That still requires real, commendable effort and grind - and is maybe harder to do than ever. Everything else is a prompt away, and even if valuable, it just does not impress.

goodbye instacart !!
Big news! @Costco is now available nationwide on @UberEats 🛒 🇺🇸 This one has great personal meaning to me (on top of tremendous impact for Uber and our customers)

otp is the best agent auth, passkeys are literally unusable inside vms
there's a lot of product magic in agents like muse or instinct in making auth into websites work. however, there still seems to be some ways to go given the various login systems you run into (passkeys, OTP via text or email, 2fa, "auth on other device").

Task creation is not yet confirmed. Do not submit it again while Codex checks its outcome

TL;DR: Owning assets is no longer optional. You have about 3 to 4 years to stack wealth and build real distribution. Once AI takes over half of cognitive work, selling your hours on a laptop won't protect you. In an AI economy, pure salaries get crushed while asset owners capture the entire upside. Own equity, businesses, or real-world reach before the window shuts.

The hottest new programming language is English
everyone spent ten years learning to code and it turns out the terminal skill was english composition. the machine will do anything you tell it. the only thing left between you and what you want is whether you can form a clear thought and put it into words

There’s an alternate reality where Slack never sold to Salesforce and is operating in full founder mode, aggressively embracing AI. I’d love to see what that product would look like. And what market cap they’d be trading at rn.

i got tired of spawning endless chat threads to manage my coding agents, so i started building them a town instead🏘️ this is @joindesa, a spatial workspace where your coding agents become persistent coworkers instead of disposable chat sessions. still early, but here's a first look 🧵

i'm still early, and i'm currently looking for a few teams using Codex, Claude Code, Cursor, or similar tools to build alongside. if your team is starting to lose track of agent work across terminals and chat threads, DM me or drop your email at joindesa.com

also, wanted to shoutout some inspirations for desa: - the team at gather (@jinen/@flippnflops/@k_m_y_l) - @gastownhall by @Steve_Yegge, and @myfirstmate by @kunchenguid - pstack by @poteto
