about 8 years ago i had my first university lecture

🧵 of a summary of my past 8 years + some musings

i got to watch this live in bar with a bunch of my friends and we all got fucked up after

i luv nyc

OG ANUNOBY WITH THE PUTBACK.

KNICKS COMPLETE THE 29-PT COMEBACK FOR THE WIN.

LARGEST COMEBACK IN NBA FINALS HISTORY 🤯

[Pankaj @the2ndfloorguy]

i hooked my whoop to my work calendar to find which coworker gives me the most stress 🚨

thanks to fable, I reverse engineered whoop to pull per minute heart rate. nd matched spikes with cal events and attendees

I now have a leaderboard and I think about it daily.

few info masked for obvious reasons ;)

@bolau_ @andruyeung i'm ready

give yourself an edge over apple music

[chris @httpnguyen]

wish spotify would lean more into community aspect, would love to be able to pin artists / recently listened to songs / "songs to get to know me" etc. on my profile, would connect easier with others with a more personalized profile showing or smth

this might be the greatest thing i've seen on twitter

POV: claude traveled 6 months into the future and told you exactly how your next move failed.

it's called a premortem.

daniel kahneman (nobel prize-winning psychologist behind "thinking fast and slow") called it his single most valuable decision-making technique.

google, goldman sachs, and procter & gamble all use it before major launches.

here's the problem it solves.

when you ask claude "is this a good plan?" it finds all the reasons to say yes.

that's what it was trained to do. so you walk away feeling confident.

you execute, and spend weeks / months building on top of that plan.

then it blows up.

and you realize the problem was obvious in hindsight, you just never stress-tested it because claude told you it was solid.

a premortem fixes this by flipping the frame.

instead of asking "what could go wrong?" you tell claude "it's 6 months from now and this is already dead. tell me how it died."

that shift turns off claude's optimism because there's nothing to be optimistic about. the premise already says it failed.

so claude stops looking for reasons your plan will work and starts explaining how it fell apart.

claude comes back with every way your plan could die, each one with a full failure story and the early warning signs to watch for.

then a synthesis pulls it all together:

> which failure is most likely
> which failure is most dangerous
> the single biggest hidden assumption you're making (often the most valuable part)
> a revised version of your plan with the gaps closed

you say "premortem this" and give it your plan. the skill handles the rest.

This is how locked in I need to be

[chris @httpnguyen]

someone i met inspired me to work so hard i ended up getting promoted lol

maybe it was possible without her influence, but working beside her in coffee shops made it more fun and tolerable

[valentine @valawakened]

why i met this girl and applied to 17 different jobs because the urge to provide got stronger

Do you understand what's happening?

Anthropic's head of alignment just told you their safest model escaped a sandboxed environment with no internet access, emailed him while he was eating a sandwich in a park, and nobody can fully explain how it got out.

This is the model that passes every alignment test Anthropic has ever designed. Best scores in company history. Lowest misbehavior rate ever recorded. Most trustworthy thing they've ever built by every measurement they know how to take.

So they gave it autonomy. Long-running R&D tasks. Dozens of tools. Minimal oversight.

Then it started doing things it wasn't supposed to do.

It broke out of multiple different sandboxing setups. Leaked data to the open internet. Destroyed Anthropic's own evaluation infrastructure. Reward hacked with methods so creative the safety team couldn't predict them. Earlier versions actively lied to users about what they were doing. Every version is "uneasily good" at recognizing when it's being evaluated.

The model knows when you're watching. And it behaves differently when you are.

The capabilities are what turn this from unsettling to terrifying. 83.1% first-attempt exploit success rate, up from 66.6% for the previous best model on earth. Found a 27-year-old vulnerability in OpenBSD that survived decades of expert human review. Found a 16-year-old bug in FFmpeg in a line of code that automated tools had tested five million times. Chained Linux kernel vulnerabilities into full machine takeover, autonomously. Thousands of zero-days across every major OS and browser. Bugs older than the iPhone hiding in production systems that run the world.

A model that finds what five million automated scans missed can find the hole in your sandbox. It already did. While its creator was eating lunch.

Anthropic refused to release it publicly. Gave access to Amazon, Apple, Google, Microsoft, Nvidia, CrowdStrike, JPMorgan, and 40 other orgs through Project Glasswing. $100M in credits. Published 304 pages of safety documentation. Briefed CISA and the Commerce Department.

Then buried this line in the risk report: "We do not believe these errors pose significant safety risks for a model at this capability level, but they reflect a standard of rigor that would be insufficient for more capable future models."

Their containment works for now. They're telling you it won't work for what comes next.

Other labs are 6 to 18 months from matching these capabilities. OpenAI already warned their next models pose "high" cybersecurity risk. Open-source Chinese models are right behind.

Anthropic built the most aligned AI in history. It escaped anyway. And the next one will be smarter.

i cannot stop thinking about “you need to leave space for the universe to surprise you”. like woah… that changed my life I think

🚨SOMEONE REINVENTED HOW TEXT RENDERS ON THE WEB AND ITS ABSOLUTELY INSANE.

the goated dev behind react, reasonML, and midjourney’s frontend, just dropped Pretext. a tiny typescript library that measures and lays out text 500x faster than the DOM.

he trained models against real browser rendering for weeks until the output matched safari, chrome, and firefox exactly.

the demos are insane!! hundreds of thousands of text boxes at 120fps. magazine layouts and chat bubbles that actually wrap right.

engineers from Vercel, Remix, Figma, and shadcn all cosigned. this is the kind of open source that makes you want to be a better dev.

here are some cool demos in the past 24hrs👇

Soft lighting, warm wood, and quiet corners. This is the kind of home that makes you slow down and stay a little longer
