This week we got our Peloton Bike and Tread delivered. We decided to update our home exercise equipment and Tammy and I both found the gear very impressive, and the live classes online very engaging. I’ve already gotten a couple of rides in and like it a lot. In some ways it’s a better spin class experience than a class in a studio! I love that you can see your performance live with everyone else taking the class. If you are on Peloton, connect with me — my username is jthingelstad!

The MBA Myth and the Cult of the CEO | Institutional Investor

Interesting analysis of well-known business school MBA's and how CEOs with those credentials do in public companies.

But regression results suggest a different result entirely. We tagged CEOs by the MBA programs they attended, formed monthly portfolios of companies broken down by the business school each CEO attended, and compared the returns of these portfolios to the broader market.  

We found no statistically significant alphas — despite testing every possible school with a reasonable sample size. MBA programs simply do not produce CEOs who are better at running companies, if performance is measured by stock price return.

What about bankers and consultants?

Lastly, we looked at how CEOs who had previously worked at investment banks and elite consulting firms performed. If Jensen’s core thesis were true, we would expect CEOs with these elite credentials to outperform the market.

We thus formed monthly portfolios for bankers and consultants. As we did with MBAs, we then ran industry-controlled Fama-French three-factor regressions. The result: Neither bankers nor consultants produced statistically significant alphas. We also back-tested portfolios designed to favor ex-bankers and consultants and found no significant edge (though consultants had a statistically insignificant edge on bankers).

We went to the lake this last weekend and I found myself playing Fishin’ in the Dark as we pulled in, and dreaming of summer, sunshine, and open water.

The ACME Protocol is an IETF Standard — Let's Encrypt

Let’s Encrypt is continuing to push the state of the art for security certificates on the web. Very happy to see this. Now hopefully more CAs will start using ACME.

From video game to day job: How ‘SimCity’ inspired a generation of city planners - Los Angeles Times

I love how impactful SimCity was to some people. I’m not a gamer, but there are a few games I’ve played a lot of. Tetris, Spectre, and a couple others. SimCity is definitely one of those. I had a city I actually upgraded and played for over a decade on and off.

There are a bunch of DuckDuckGo things I didn’t know even existed. The ! searches are a neat feature. 👍🏻


How to Reduce Anxiety Through Meditation and Buddhism - The Atlantic

Some surprising numbers here on how many people are getting into meditation and Buddhist philosophy. I found it a little shallow that the author only points the finger at the classic “everyone is so busy” thought. I think there is a real connection between the near universal adoption of mobile devices along with social media that are driving this. 🧘🏼‍♂️


800+ Million Emails Leaked Online by Email Verification Service - Security Discovery

I found out about this one thanks to a notice from HaveIBeenPwned. They had four addresses in my domain. The surprise for me was that I’ve never given my email address to this service, but I guess other services I use must have been using them for email validation.
