Congrats to our portfolio company @AlmanaxAI !

[Francesco Piccoli @francescpicc]

.@AlmanaxAI is joining @depthfirstlabs!

@mmwtsn and I started the company two years ago because we'd grown tired of seeing weekly multi-million-dollar hacks destroying blockchain companies and stealing people's life savings. We believed the industry needed to move from annual security audits and pentests to continuous ones, and that AI would eventually get us there. We were among the first to see the potential of AI in cyber and build new solutions in this space.

When we started, most security teams told us our product wouldn't work, they didn’t need more findings, and they didn't trust AI to be good. But then we saw how the commercial tools our clients were using were missing many of the vulnerabilities we were detecting, while producing an absurd number of false positives.

We ended up working with some of the largest blockchain companies: Solana, Stellar, Aptos, Privy and Bridge (now part of Stripe), DFNS, Algorand. When people didn't believe, we showed them results: we found issues in Vitalik's code (arguably one of the best software engineers on Earth), ethically disclosed hundreds of vulnerabilities (to Ripple, Coinbase, Fireblocks), and won security competitions against thousands of researchers.

As we progressed, we realized that while crypto companies were among the most vulnerable (exploits directly steal money), the problem was widespread beyond blockchain. The rise of vibe coding created an enormous new attack surface and new models and harnesses were detecting vulnerabilities that had gone unnoticed in software packages for decades, some of which power most of today’s internet.

The time between CVE public disclosure and first confirmed in-the-wild exploitation has dropped from 2.3 years in 2018 to eight hours today. This and the release of frontier cyber models shook the industry. So we expanded our product support to languages and tech stacks used widely by enterprises.

But the scale of what needs to be done requires more than what any one small team can do alone

We believe joining forces with depthfirst will significantly accelerate our shared vision to secure the world’s software.

depthfirst is already swinging at the same future we set out to build, with the team and the resources to lead the way. Their bet, and now ours, is that the next major security platform will be in product security. As their investor @arshammem put it, every category eventually gets one company whose name becomes synonymous with it: Palo Alto Networks for the network, CrowdStrike for the endpoint, Wiz for the cloud. Product and application security, notwithstanding many attempts, is still left without a crowned victor.

We think depthfirst can be that company.

Thanks to our great team, investors, and customers who believed in us and shared our vision of the world.

Our ambition is now even bigger and we’re excited to build that future with @qasimmith, @andreamichi, Daniele, and the entire @depthfirstlabs team.

We built a game. It's called Mogg. Come give it a try.

I think folks waking up to red lights in the cabins would cause panic though...

[@levelsio @levelsio]

Someone has to tell the people designing airplane cabins that blue light is the worst thing you can do for sleep

It suppresses melatonin, disrupts your circadian rhythm and just make you sleep bad

But they're somehow all doing it

For optimal sleep it should be warm red lights

We seem to be experiencing an all time historic moment of the World Cup

Me crucé con esto, Messi está casi 6 desviaciones estándar por encima de la media de delanteros de grandes ligas en cuanto a goles y asistencias en 90 minutos. Estadísticamente es prácticamente imposible que vivas para ver a alguien así

[Kyle Libra @kylelibra]

Disappointing decision by NY officials.

[signüll @signulll]

what a fucking tragedy for nyc.

the same dumb resistance happened during the uber saga & now you’re watching the same shit play out again with autonomous cars.

the reality is that humans should not be operating metal death machines forever. esp in a city where taxis have spent decades gaming routes, ignoring pickups, driving like maniacs, & treating the meter like a side quest. uber fixed some of that, then slowly became expensive as hell, degraded, & unreliable in its own stupid way.

collective decision making of humans is often so so damn stupid.

[Kyle Libra @kylelibra]

Wait...does this mean all the claims of people vibe coding 8 figure business with one shot prompts aren't true?!

[Kyle Libra @kylelibra]

That's a lot of Knicks fans

My favorite video I’ve ever taken.

Absolutely surreal.

Determination stil matters more than anything else.

.@mntruell launched Cursor 8 times, and nobody cared.

Don't give up.

[Kyle Libra @kylelibra]

This...actually seems like a pretty great idea? Seems like it would make everything a lot more fun to watch. And it would make it more about the teams/brands.

Who would pay the drivers though?

[Fórmula Directa @FormulaDirecta]

💡 Carlos Sainz: "Tengo una idea para la F1: correr dos carreras con cada uno de los coches de la parrilla durante la temporada"

👉 "Entonces el piloto es parte de la F1, no es parte de un equipo, es un cliente que la Fórmula 1 contrata para llevar los coches".

👉 "Entonces yo tendría mi oportunidad de hacer dos carreras con Williams, dos con Mercedes, dos con Ferrari... Todos los pilotos tendríamos exactamente la misma oportunidad de ganar el Mundial".

👉 "Conseguirías desasociar por completo las marcas de los pilotos. y así tendrías un campeonato real de pilotos y un campeonato real de marcas".

This mostly seems to be the SpaceX thesis.

[Boring_Business @BoringBiz_]

Everyone buying SpaceX right now waiting for the fundamentals to justify the price

What a weekend

New York doesn’t know what to do with itself right now

So fun

[derek guy @dieworkwear]

what a great city

It is a great time to be a New Yorker

Amazing project

[Nav Toor @heynavtoor]

A GUY AT GOOGLE DEEPMIND MADE AN ISOMETRIC PIXEL-ART MAP OF NEW YORK CITY AND PUT IT ON THE OPEN WEB FOR FREE

it's called https://t.co/8fAASvEmXT

you open the tab and the city is just sitting there in classic SimCity 2000 isometric pixel art. you scroll. and it keeps going. and going.

i zoomed in on midtown and i could read the H&M signage in times square. in red. as actual pixel-art letters on the side of a building.

i could see the crystalline spire of the Bank of America Tower poking out of a clump of skyscrapers. individual rooftop HVAC units. tiny green roof gardens. the little driveway loops in front of the hotels.

he estimates the map needs roughly 40,000 tiles. nothing is a placeholder.

the guy who made it is Andy Coenen, a senior staff engineer at Google DeepMind. he is not a pixel artist. by his own admission he is "a former electronic musician."

what he actually did is kind of insane:

> pulled NYC's geometry from the Google Maps 3D tiles API

> fine-tuned an open-source image model (Qwen-Image-Edit) on ~40 hand-paired examples of "satellite tile → pixel art tile"

> spun up 50 parallel instances on rented GPUs and generated tens of thousands of tiles in a few hours

> the fine-tune cost him 12 bucks

his own stated mission for the project, verbatim, is one sentence: "what's possible now that was impossible before?"

apparently the answer is "one engineer can pixel-art most of a metropolis for the price of a sandwich."

and the wildest part to me is he didn't sell it. no signup. no paywall. no NFT. you open the URL and the city is yours to wander.

the post landed at 1,325 points on Hacker News and topped bestofshowhn's 2026 list.

we live in a timeline where a senior engineer at one of the largest AI labs on earth spent his nights pixel-arting Manhattan for fun and then gave it away.

the internet is healing.
