Lex Fridman brings in another legend to interview for his podcast, Ray Dalio.

Ray Dalio is the founder, Co-Chairman and Co-Chief Investment Officer of Bridgewater Associates, one of the world’s largest and most successful investment firms that is famous for the principles of radical truth and transparency that underlie its culture. Ray is one of the wealthiest people in the world, with ideas that extend far beyond the specifics of how he made that wealth. His ideas, applicable to everyone, are brilliantly summarized in his book Principles. This conversation is part of the Artificial Intelligence podcast.

In this episode of BlockTalk, watch a discussion on Bitcoin and Lightning technology with Samson Mow, the CSO of BlockStream. They cover Bitcoin and Lightning technology as well dive into how companies like BlockStream are innovating on top of the Bitcoin protocol.

With BitCoin prices on the rise again, the hype machine has turned its focus back onto the technology. In a few days, expect the rally to retreat again and pundits to say something along the lines of “Blockchain has no practical use.” They are, of course, wrong and Siraj Raval explains (and demontrates!) why in this video.

Healthpass is a secure cloud store for all your health records! This serves patients by giving them one place to store and view all of their health data across all providers globally. It serves providers by ensuring that health records are stored securely via a blockchain and allows them to see a patients previous health history easily. To build this app I used Node.js, Firebase, Bitcoin’s Blockchain, Paypal, Stripe, Tesserect.js, BioBERT, and a health data visualization library called hFigures. The reason I built this app is to give you an idea on how a “bitcoin” startup would look practically, programmatically, and visually. I hope this inspires you to build something cool and even managed to fit a rap about SHA-256 into it. Enjoy!

Since it’s Saturday morning and, once upon a time Saturday mornings were for cartoons, I figured this would be the ideal time to post this cartoon about the emergence of Bitcoin in the midst of the 2008 financial crisis.

Bitcoin awakens to a chaotic world following the 2008 financial crisis. With only a few words to his young child, Satoshi disappears, leaving Bitcoin with more questions than answers. Fortunately, a benevolent ice cream truck owner (Jones) takes Bitcoin under his wing in a search to find his father.

The cartoon is embedded below, but be warned, it’s not for kids and there’s a lot of foul language.

You have been warned.
