Lex Fridman Podcast - #104 – David Patterson: Computer Architecture and Data Storage

David Patterson is a Turing award winner and professor of computer science at Berkeley. He is known for pioneering contributions to RISC processor architecture used by 99% of new chips today and for co-creating RAID storage. The impact that these two lines of research and development have had on our world is immeasurable. He is also one of the great educators of computer science in the world. His book with John Hennessy “Computer Architecture: A Quantitative Approach” is how I first learned about and was humbled by the inner workings of machines at the lowest level.

CoinDesk Podcast Network - BREAKDOWN: Welcome to the Groundhog Day Economy (PS, It Sucks)

As states shutter economic activity because of preventable COVID-19 outbreaks, it’s deja vu all over again. 

This episode is sponsored by Bitstamp and Ciphertrace.

This is a movie we’ve seen before:

  • Rise in what could have been preventable COVID-19 cases
  • A call for shutdowns (plus voluntary closures)
  • Rampant politicization of health and economic issues rather than common sense approaches
  • Persistent jobless claims plus new layoffs 
  • Wall Street nerves turning into new Federal Reserve and Treasury action


Rinse, repeat, economy!


This week on The Breakdown:

Monday | Macro Investors Sound Off! Featuring Ari Paul, Spencer Bogart and David Nage

  • Some of the smartest investors in the crypto space share how they think the larger macro context is shaping interest in bitcoin and digital assets.


Tuesday | Oil 101: How Easy Money Enabled the Shale Revolution, Feat. Tracy Shuchart

  • An oil and commodities expert breaks down how the shale revolution reshaped global energy power and why oil went below $0 earlier this year.


Wednesday | Bull vs. Bear: Who Has the Economy Right?

  • From markets to real estate to the dollar to retail, the data on whether the market is recovering or not is hella confused.


Thursday | Is Scam Selling Suppressing the Price of Bitcoin?

  • Scam selling, a big win for privacy from Apple, new jobless claims in the “whack-a-mole” economy and the biggest BTC options expiry ever.


Friday | How Monopolies Sow the Seeds of Their Own Destruction, Feat. Tuur Demeester

  • The managing partner of Adamant Capital joins for a conversation about what the Protestant Reformation and the French Revolution can teach us about bitcoin.

Byzantium And The Crusades - The Fall Of Byzantium Episode 3 “What Is The Truth About Romanos Diogenes?”

This podcast series tells how Byzantium was central to the Crusades. It is based on the book "The Byzantine World War" by Nick Holmes. In this episode, we ask the question why do historians even today tend to write off Romanos Diogenes' attempts to save Byzantium? The answer takes us on a journey through the writings of the main Byzantine chroniclers of the time. We learn how the true story was purposefully hidden by Romanos' enemies and is still confusing historians today.

Please take a look at my website nickholmesauthor.com where you can download a free copy of The Byzantine World War, my book that describes the origins of the First Crusade.

Consider This from NPR - White House Task Force Briefing Is Back; Texas Emergency Rooms Are Filling Up

COVID-19 cases are at an all-time high in the U.S. And for the first time in almost two months, The White House Coronavirus Task Force had a televised briefing.

In Texas on Thursday, 6,000 new cases of the coronavirus were reported. An ER doctor in Houston says beds are filling up and they are running out of places to send patients.

Some states are closing down bars and restaurants, again, as COVID-19 cases continue to rise. But NPR's Scott Horsley explains that customer traffic has already been dropping for days.

Even now, it can still be tough to get a coronavirus test especially, as NPR's Kirk Siegler reports, in tribal communities.

Plus, with many movie theatres closed, the films topping the box office are a bit ... retro.
