How a Web2 Company Uses Crypto to Power Open Data APIs

Thank you to Art, Fred & Jake for reviewing and providing feedback on this post! Question: Does your software use APIs? Where do you find the endpoints? How do you get the specifications? How do you ensure quality? šŸ¤” tl;dr There is a big opportunity to build the ā€œGoogle home pageā€ for finding and accessing open data sources and services. An open marketplace of APIs does not exist today. API Discovery and RPC Quality are the two core primitives necessary to enable this. ...

Nā‚‚O: Revisiting the best Nuclear Investment Vehicle

tl;dr If you’re invested in URA because of Uranium, consider diversifying that position into other ETFs or fully moving it over to NUKZ to broaden your nuclear exposure. This is not financial advice. Special thanks to ChatGPT, Google, Reddit and Claude for helping me research, prepare, write and edit this post. Last May I wrote about why I’m allocating a large portion of my portfolio to Uranium with a bullish perspective on the nuclear sector at large. ...

My Top `X` 2024 Recommendations

Last year was the first time I published a ā€œTop X Recommendationsā€ blog post to close out the year. I heard from about half a dozen people who found at least one recommendation interesting or useful—which means there were probably even more who never mentioned it but still got something out of the list. So, I figured I’d do it again! In the very likely scenario that you either don’t have the time, interest, or attention span to read this whole thing, just scroll to the very bottom because the last one is by far my favorite. ...

Aspire to Inspire Your Present Self

Earlier this week I asked myself: ā€œWhy do I listen to so many podcasts?ā€ This led me down a mental rabbit hole of reflection while I sought an answer to: ā€œWhat is the source of my intrinsic motivation?ā€ I came to the conclusion that if I were to listen to a podcast (or read a blog) of myself five years in the future, I want to be inspired by it today. Today, at 32, I’m hoping my 27-year-old self would be inspired by this blog, just as I currently seek inspiration from him. It’s how I know I’m achieving my full potential at every step along the way. ...

Move Fast & Document Things

I’m going to share a small secret: a perfect solution to software documentation does not exist. It’s hard to generalize what ā€œgood documentationā€ entails. It depends on the team, the product, the timing, and a million other things. Have you found PMF or are you iterating? Are you a small tight-knit team or are you scaling? Is your team remote, in-office or hybrid? Is open source and external collaboration a key component of your value proposition? I’ll stop here before it gets boring… ...

Annotated Presentation: Relay Mining - Cryptographically Incentivizing Non-Validating Nodes

Inspired by Simon Willison’s How I make annotated Presentations, I figured I’d annotate a presentation I did at ethcc.io in July 2024. He says it best: Even with that quality of presentation, I don’t think a video on its own is enough.

Vibe Checks Are All You Need

Why I’m Allocating 10% of My Portfolio to Uranium

tl;dr Artificial Intelligence (AI) computing requires substantial energy, increasing the urgency for sustainable, scalable, and modular energy solutions. Major tech companies are actively adopting and investing in new ways to tap into nuclear power sources. The spot price for Uranium doubled over the past year due to a supply-demand imbalance, as current uranium supplies struggle to meet the demand from nuclear reactors. I argue that the current market presents a good entry point for diversifying into the uranium sector. Macroeconomic tailwinds could suggest a strong outperformance over the next decade at the cost of short-term volatility. I outline my thought process for choosing as a vehicle to do so. ...

Why was Sam Altman fired from OpenAI?

If you’ve visited X in the last 24 hours, seen OpenAI’s Blog, or simply opened up Google, you’ve probably heard that the board of OpenAI has fired its CEO, Sam Altman.

Data Odyssey: Taking Control of my Rotten Tomatoes

The Exposition: Roll Camera on Your Average Movie Watcher Not much different from your typical consumer, I’ve been a fan of films and TV shows since I was a kid. The genres have changed and my viewing frequency has dropped, but the essence remains. Once streaming became available, I never got into the habit of binging shows with the exception of a few cases (cough Lost cough); if I really like a show, I try to prolong that experience for as long as possible. About a decade ago, I realized that I was investing so many hours consuming the hard work and passion of others, so it seemed fair to spend a few minutes leaving a public rating or review.
