Great software feels like it's reading your mind. It knows what you want before you do.

everyone is saying this is huge (and rightfully so) but my question is: is it reversible? can you turn any neural network into a human readable javascript program? that has massive implications for mechanistic interpretability. imagine opening Claude's source code and tracing every decision it makes.
My dear friends, I’d like to show you my latest toy project Introducing Handwired: turn your regular JavaScript code into a neural net! - no training - exact outputs vs the JS program - fully differentiable All runnable in a browser, without GPU

RIP cursor 2022 - 2026 one of the greatest products in recent years. there's no competitors that come close in terms of product experience for developers.
We've unified plans across Grok, Cursor, and X Premium. Introducing The X Subscription.

As CEO of Product Hunt, I see hundreds of launches a week. One trait separates winners from losers. Every few months, new models come out. Some products become better, effortlessly. Some don't improve, or become irrelevant. This property needs a name. I'm calling it Buoyancy. Buoyant startups rise with model improvements the way a boat rises with the tide. Anti-buoyant startups come in two flavors: over-scaffolded (which hinders the new, smarter models) and too thin - which makes them redundant when models improve. To be buoyant, you need a "hull" - usually proprietary data, a vertical-specific harness, network effects, or distribution advantage. This hull keeps you buoyant as models improve. Hulls are the new moats. My number one advice to startups in 2026: Be buoyant. Find your hull. (Full essay on my blog)

give it 3 months before Anthropic Hires him
Ben Affleck reveals he writes Python, understands convolutional neural networks, worked extensively with GPUs, and used his celebrity status to get private looks at Google and OpenAI’s video models “I’ve always been kind of into computers since I was young. Then, when film started to move from analog film to digital, I became more interested in that aspect of it. The visual-effects workflow for many years has included machine learning, so I can write pretty shitty Python scripts and stuff like that. “With convolutional neural networks, which were the precursors to what the transformer can do, which is much more computation simultaneously, you would do things like look at what’s called a tensor. That’s the numerical translation of a visual image in numbers, like the batch number, the frame number and the red, green and blue values of each pixel in each frame. It’s just that simple. That numeric is called a tensor. “You’d use a convolutional neural network to identify patterns that reveal what’s called edge detection or feature extraction, which is identifying patterns well enough to know, this is where the window ledge is, so we can more easily take the green-screen image out and replace it with something. “That was familiar to me early on because, prior to Artists Equity, I had a small visual-effects company. I’ve worked with GPUs a lot too. The visual-effects guys said, ‘Hey, you should see. There are a couple: Google and this other company, OpenAI, are doing really interesting stuff with transformers in video.’ “I’ve learned that I can actually just call up and go, ‘Hey, it’s Ben Affleck. Can I come see what you’re doing?’ Sometimes people say yes, to my astonishment.”

more YC robotics startups please!
my dad and i built a robot for your parents. today we’re launching @rhem_labs our family spent nearly 20 years caring for my grandmother and aunt at home. we saw small health changes go unnoticed between check-ins. and simple things, like making a call or booking an appointment, meant waiting for someone else to help. we built the robot we wish they’d had. your parent just talks to Rhem. it helps make calls, book appointments, manage reminders, and get everyday things done online. through the family app, you can follow changes in health readings and routines, see what Rhem handled, and step in when you’re needed. your parent chooses what to share. Preorder Rhem Today → rhem.ai

believe it or not, this has always been the moat.
the only moat left is caring about your project past two days

You can just learn things (with opus 5.5) I asked it to turn @karpathy's microgpt into a visual factory. Now I can watch the words as they go through the language model and look closer at any part I don't understand. Incredible tool for building intuition behind language models.

In your 20s and 30s, the urge to look successful will tempt you to put on a show for an audience that isn’t even paying attention. Remember: the goal is to actually build a good life, not to convince everyone else that you have one.

performative productivity
I have 22 Claude max accounts, and the current promotion - an optional weekly reset that you can spend any time before Oct 22 -- is a lifesaver for fuel tuning. I know it makes it harder to predict their compute loads, but I'm super grateful for this reset form factor.

everything is fake - posts on here, ghostwritten - statistics, misleading - benchmarks, bullshit - reviews, paid for nearly every company is doing this. the frenzy over ai is showing me so few founders have any backbone

Anthropic is firing on all cylinders
Introducing Claude Sonnet 5.5, the second model in the Claude 5.5 family. It’s a clear upgrade over Sonnet 5, runs more than 30% faster, and costs up to 30% less for most work.

it's crazy how fast notion went from beautifully crafted software to vibe coded bloatware
5.5 is the first time i've felt confident enough to start ripping a ton of Saas tools out of my business and building them myself for my team. Yes, I'm not going to vibe code an entire app (like Notion) But I am going to vibe code one that's better for me and my small team. Almost every app I pay for, I use maybe 10% of the features. I'm currently using Opus 5.5 to build an internal tool that takes the few features I actually use from 5 different apps and puts them in one place. - 5 logins... now 1 - I can add a features freely almost immediately - It's built around how my company works, not how some other company thinks I should work

I recently watched the famous lecture by the late MIT professor Patrick Winston, titled ‘How to Speak.’ He opens by saying: “Your success in life will be determined largely by your ability to speak, your ability to write, and the quality of your ideas, in that order.” Freaking brilliant.
