when you meet someone, you can almost always tell which social media platform fine tuned their brain / thoughts. esp in nyc.

e.g. most ppl likely now have an insta personality / aesthetic outlook (esp women), or a reddit personality (likely dudes), or maybe even an x personality (weirdos) to some extent. i guess chatgpt is likely the next personality influencer too.

you are a product of your thoughts, & your thoughts are the product of your feed & of likely next the personal ai agent you let in to your life.

This pattern never repeats, and it still has fivefold symmetry.

Two rhombi do the work: a thick 72° tile and a thin 36° one. Turn it 72° around the center and it matches itself. Slide it any distance and it will not.

Inflate by φ = (1+√5)/2 and a copy of the same tiling appears inside, because φ² = φ + 1. Quasicrystals found the same loophole in real matter.

before ai it was cognitively expensive to be a programmer cuz you had to really use brain cycles for everything, from architecting, to even using the right variable names etc. it was genuinely draining.

& if you programmed for a whole day, you were fucking tired. even code reviews required you to think deeply & you had to be aware of the entire code base to some extent too. so not only did you have to have context loaded, you had to do manual inference if you will.

ai completely eliminated all of this strain.

talked to a guy from anthropic for a long time last night. fascinating conversation.

& believe it or not, one of their biggest problems is still hiring.

there simply aren’t enough exceptional ppl, esp for long term high conviction bets where the stuff is not obvious yet. i.e. people who can independently generate good judgment under extreme ambiguity.

one of the strangest things about moving from new york to sf was realizing how often extremely important things happen here in settings that don't feel important at all

i lived in new york for four years. i sometimes spent entire days moving icons around in powerpoint, but i was doing it in a skyscraper with great views, surrounded by attractive people in patagonia vests. afterward i'd walk onto a packed street and go to a beautiful restaurant

even when the work itself was mundane, everything around it told you it mattered

sf is almost the opposite

the blue bottle in south park feels like a normal coffee shop. it is also a place where an absurd amount of capital gets allocated

sand hill road is one of the most powerful financial centers in the world and looks like a collection of dentist offices

you'll meet someone dressed like they just rolled out of bed who can't make eye contact and discover later that they control billions of dollars or have built a product you use every day

i've been to parties where almost everyone had raised millions of dollars or built products used by millions of people. in another city, each person would have seemed like a big deal. in sf, they were just standing around a cramped apartment at a "party" that honestly wasn't even that good

i used to live in a closet in a slightly dilapidated hacker house with creaky floors and old furniture. people who lived there went on to create companies worth tens of billions of dollars

new york puts a lot of effort into making importance visible. sf often seems actively uninterested in doing that

some of this is probably because sf is more focused on creation than consumption. some of it is the personality of builders, who often care much more about the thing they're making than the room they're making it in

but i think the lack of polish also lowers the barrier to entry. you don't need to look important before doing something important here

new york makes ordinary work feel important

sf makes important work feel ordinary

Shopify billionaire co-founder & CEO Tobi Lütke — one of the most analytically rigorous founders alive — uses affirmations.

His exact words:

"If you tell yourself or write down something about yourself 100 times, it writes into the neurofrontal cortex at such a deep level that your brain will start reconciling you to that. It just works."

His personal example:

He was terrified of public speaking.

For one week he sat down every day for 10 minutes and wrote: "I love public speaking."

A week later the fear was gone.

"It's not like a placebo. You just actively change your neurofrontal cortex in this moment."

Your brain starts shaping your behavior around the identity you rehearse most.

The gap between a 10x AI user and a mediocre one comes down to two abilities:

1. Domain expertise. You know what a great result looks like because you've done the work for years. This is your ceiling, and it becomes the agent's ceiling
2. Translation. You can pass your taste and standards to the agent through context, references, and iteration

The second is a skill, learnable in weeks.

The first is a career. No AI will hand it to you.

you can build a working HTTP server in x86-64 assembly

just Linux syscalls

create a socket, bind it to 127.0.0.1:8000, listen, accept connections, write an HTTP response, close the socket

the entire server is just raw assembly talking directly to the kernel

The Apple Neural Engine wasn't supposed to be used for anything other than AI. And then someone worked out the API.

And then I took that proof of concept and got claude to build a donut rotator with it. For no reason.

But, hey, a 38 trillion ops/second piece of silicon gotta be useful for something non-ai related? @Fudmottin could get it to count primes !

We built a high-speed jet interceptor in two weeks. Meet the first SABLE prototype.

As incoming drones become cheaper and faster, air defense needs to catch up.

SABLE and HUNTER are the cornerstones of our Air Defense as a Service (ADaaS) offering, built to protect critical infrastructure.

@ycombinator teaches us to “build something people want.” We build something people need.

the secret is, it's actually really simple.

if you want to be a writer, write everyday.
if you want to be a runner, run everyday.
if you want to build a business, solve a problem, and see if someone will pay you for it, everyday.

most people overcomplicate things because it's easier to chalk it up as "impossible" than wake up everyday and do the boring daily activities that get you 1% closer to where you want to be.

Four quantum numbers alone force the chemical elements into this diamond lattice of shells and orbitals. The integer n labels each shell.

s, p, d and f orbitals hold 2, 6, 10, 14 electrons from the quantum number l.

This geometry solves the multi-electron Schrödinger equation. It dictates semiconductors in chips, catalysts in chemistry, and materials for quantum devices.

What appears as a table of matter is pure quantum mathematics made visible.

Beglaubigt.de turning German company formation into a ChatGPT app is such a smart distribution move.

People already ask ChatGPT how to set up a company. Their API and MCP server let the app collect the details for a GmbH or UG inside the conversation and then return a secure checkout link. Beglaubigt.de coordinates the notary appointment, Handelsregister filing and formation documents.

Instead of waiting for founders to find its website, the service can now appear at the moment they express intent.

I found a previously undocumented passive Windows backdoor I’m calling SLEEPWALKER. Its defining feature is a custom command language with 23 instructions. Instead of receiving conventional commands, it runs encrypted bytecode programs that can combine scheduling, nested programs, staged payload delivery with SHA-256 verification, decompression, network communication and in-memory shellcode execution.

The analyzed file is an unsigned DLL that masquerades as Microsoft's dpapi.dll, uses forged ESET metadata and activates only when side-loaded by ESET's Management Agent program ERAAgent.exe. SLEEPWALKER does not beacon or open an obvious listening port on its own. It monitors network traffic and stays dormant until it detects a specially crafted packet carrying an AES-256-CCM-protected task. It supports TCP, UDP, ICMP, SMB named pipes and VMware VMCI. VMCI can carry traffic directly between a VMware guest and host without using a conventional network interface. SLEEPWALKER also implements a DNS trigger that uses Base32 to carry encrypted tasks inside DNS labels, although the analyzed sample does not enable it.

The full analysis documents the bytecode format, all 23 instructions, encryption, DNS encoding, trigger logic and network transports. It also includes IOCs, a YARA rule and a PowerShell scanner.

If you believe you have been targeted by SLEEPWALKER or have found a related sample, please contact me. I created the SLEEPWALKER Analysis Toolkit to decode its bytecode, examine artifacts and safely reproduce its receiving pipeline without executing commands or transmitting data. If you suspect you've been infected, I am happy to share this toolkit with you, alongside a mitigation guide providing investigation steps and a remediation script for use after detection.
