With fundamental physics I feel like we beat the game in the 70s, and now we're just going back and collecting treasure chests (condensed matter and low temperature and plasma) and trying to beat the hidden superboss (quantum gravity)

My first entry into “real” math! Spent many frustrating hours trying to comprehend even basic proofs…

3 for the price of one! You will learn Multivariable/vector calculus, linear algebra and differential forms in one place, with this ''Unified approach'' book by John and Barbara Hubbard, in my opinion, a masterpiece in pedagogy. Written for the complete beginner, with a focus on worked out examples, an easy to read text which guides you throughout your journey, and probably the best introduction to differential forms and exterior derivatives that I've seen on paper (chapter 6 ), it would be hard for me to find a better starting point to these topics than this book. I really wish I had known Hubbard's text when I had to learn vector calculus!

LLMs are so powerful yet remarkably dumb. It accurately extracts tabular data-no easy feat- but flubs the trivial calculation. It gets close (real answer: 2,193) which itself is uncanny. Why did it hallucinate something reasonable (vs. wildly off)??

Pretty intense winds here in the mission for a bit of time. Watched a tree fall over from the window, a flash a block away, and then no power

Before you drop $3,000 on an overpowered MacBook Pro M4, consider buying a Mac mini to keep on your desktop and an Air when you're on the go. I've been doing it this way for years when I realized my MBP was docked most of the time as an overpriced desktop.

This saved us a lot of lost sales— this is table stakes for most large opportunities. At the time we debated whether or not it was premature; in hindsight we probably waited a tad too long.

I spent many frustrating hours freshman year reading this book. I went to college with very little experience in theoretical math and found myself completely outclassed by my classmates. After this class, I gained a lot of confidence. I never was good, but I could try hard.

Michael Spivak's ''Calculus on Manifold'' provides you with the basics on manifold and calculus, in this short 150 pages text. Chapter 4 and 5 will be of interest to my physicists friends. What's great is that it's also available publicly, link to the pdf in the comments

I got to chat with @brettdg about how AI/ML is transforming a whole host of industries, including mortgage underwriting. Brett was one of the first engineers who I had the privilege of working with and he taught me so much about eng. Proud to be an @Initialized portfolio co.

HomeVision uses AI and machine intelligence to offer comprehensive collateral underwriting. On our latest "High Bit" episode, HomeVision cofounder @vincentchu talks about how they’re automating real estate valuations at scale. Vince shares insights on the rapid evolution of AI and the importance of building trust in automated systems. It’s not just about deploying the tech—it’s about making sure it’s practical, reliable, and ready for real-world decisions.

Using @cursor_ai in my workflow has taken a bit of getting used to. It generally works pretty well, but every once in awhile it'll sub in some random string from what I assume is the training data of the underlying model. @jkraut_ dis you?

Something really fun about hacking together terminal-based tools. I needed a tool to visualize and inspect protobuf files, and I cooked up a tool to do just this using github.com/rivo/tview

I’ve been meaning to buy this book for awhile- the 50% off code was the thing that put me over! 🙏 @AxlerLinear for such a refreshing take on this beautiful subject.

I didn't realize it at the time, but this was the start of my tech career. @posterous was my foot in the door and where I learned how to build. I got in by building a Facebook Plugin for @agarwal and @garrytan. This job was my red paperclip- everything after came from this.

This: so many bugs, errors, challenges, and tradeoffs in web dev ultimately come down to understanding this fact. If you develop for the web you are working on a *distributed system*. Even worse, you have little control over your clients (who must be treated adversarially!).

Many forget that the client-server architecture is a *distributed system*. The request-response workflow we have historically used helped us forget it. However, if you keep a WebSocket connection open with bidirectional data, you can no longer ignore it. 🧵

Despite having nearly the same experience in college, I chose to get my PhD, thereby denying myself the opportunity to found my generation’s Amazon. 😭
