okay: ℂ next question
you’re a numbers guy? name every number.
I thought I had an intuition for aerodynamics and then the Boeing CH-47 Chinook transporting a tree showed up.

Go sign a lease on a manufacturing space and start reindustrializing. Here’s how: (1/30)
The best and hardest year of my life. If you like circuit boards you'll like what we are announcing on Wednesday.
One year of Diode. Our boards are now powering real products and real teams. Excited to share what’s next. T-2 days
New vertically-integrated American minerals company just dropped. Hell yeah!
For the past 10 months, we've been building a new company in the minerals space, and I'm excited to share more about Mariana Minerals - a software-first, vertically integrated minerals company. In the 1970s, the energy crisis started a decades-long concerted effort to achieve…
Thought this would be fun - I created a montage of a bunch of Ben’s builds over the years Compressed ~50 YouTube vids into 42 seconds
My first interview with Ben Nowack (@bennbuilds) co-founder of Reflect Orbital Reflect is launching mirrors into space to sell sunlight after dark. 0:29 Moving sunlight 3:04 Building hard things 5:01 Making bombs as a kid 6:46 Building RC planes 8:32 Getting materials from the…
I'd hire a 2.0 GPA who built this WAY before a 4.0 GPA who has never built anything in the real world
yeah i’ll believe that when FISH can DRIVE 😒 oh snap wait a minute
The internet was created because the DoD needed a communications network that could survive a nuclear war
reminder: internet was created to save time.
What an excellent choice of header photo in the NYT article on @reindsummit
Keil's Law: Megaprojects always cost more and take longer to deliver than you expect, even when you take into account Keil's Law
Who’s doing a good job at nuclear?
Should I start a new season of First Principles? I don't really think the world needs another podcast... but *technical* interviews are unique & not something I see elsewhere. The first two seasons featured: ‣ Theseus — GPS-denied drone navigation ‣ Aalo Atomics — nuclear…

Today we're excited to share a glimpse of what we're building at Generalist. As a first step towards our mission of making general-purpose robots a reality, we're pushing the frontiers of what end-to-end AI models can achieve in the real world. Here's a preview of our early…
If I'm reading this right, this also means that my siblings made me dumber by being born 😂
First born children have higher IQ than their siblings.
The secret is to get your dreams out of your head and onto paper. The more specific you get, the more you realize those dreams aren't actually that far away
most people don’t actually need money to achieve their dreams. it’s cope, a lullaby for the chronically inert. it’s the excuse people cling to when the real cost is showing up every day. you’re not broke, you’re scared. you are one blog post or project away from greatness. you…
Every time you see a headline like this, you should think: "Nice, I am now capable of winning a gold medal at the International Math Olympiad." These tools are power-ups for *your* brain!
Today, we at @OpenAI achieved a milestone that many considered years away: gold medal-level performance on the 2025 IMO with a general reasoning LLM—under the same time limits as humans, without tools. As remarkable as that sounds, it’s even more significant than the headline 🧵

1/N I’m excited to share that our latest @OpenAI experimental reasoning LLM has achieved a longstanding grand challenge in AI: gold medal-level performance on the world’s most prestigious math competition—the International Math Olympiad (IMO).
