Some nuggets of wisdom from Charlie Munger



Stripe Press recently released a new edition of Poor Charlie's Almanack, exactly a week after Munger sadly passed away. I had preordered the book and picked it up a few weeks after release. There are many good quips and general good advice in there and I will share the most interesting tidbits to me.

First, the "mental model checklist". Charlie Munger is famous for his "mental models" framework and many outlets - books, websites, content writers - push mental models either because they believe in the framework or, more cynically, because people buy it trying to be more like Munger (that is, rich). I don't have a lot to add here, other than that when I read about this "mental models" frameworks, it never came to me the idea of a literal checklist. But that's how Munger explains his framework: a literal checklist.
You go one by one, see which ones apply and - crucially important, according to him - when many apply (as in most real life cases) one has to figure out how these systems interact. I don't know if I will adopt this practice, but whenever anyone refers to "mental models" to me in the future, I'll make a note to try to use them as a checklist instead of just learning them and hoping my subconscious mind does the job of pulling the right ones at the right time.

To be honest, if I could risk a lesson that Munger may or may not have expressed himself, I'd say he's very critical of relying on your subconscious mind to make decisions for you. One should be aware of how one thinks when making decisions.

The second lesson that I took a liking for was his view of a little unfairness being more fair than fairness in all interactions. Specifically, he mentions that in the U.S. Navy a captain's career is over if his ship turns around. It doesn't matter if it was his fault: his career is over. This may not be fair to the individual captain, but keeps every other one on their toes and the increased tension saves many lives as a result. Sometimes I wonder if this, intentionally or not, is happening in high-performance but high-stress careers, famous for being unforgiving. Maybe it's better this way?

JIT and GIL removal are not even my most anticipated Python 3.13 features

     Fun story: I came to Python through data analysis - so I wasn't a "python/programming expert" - and for an unreasonably long time used exclusively csv, parquet (thanks to pandas) and later JSON to persist data from my projects (local projects, of course. Mongo, RDS and Athena were always there). At work this was 100% enough (mostly parquet), but it always felt a little clunky to use JSON for a quick cache, especially when said cache grew larger for longer running processes or longer projects. Opening, parsing then serializing back again becomes slow surprisingly fast.      Then after a few years I decided to start using SQLite. I knew it existed, but always felt like it was a bit of a hassle to define a schema and "get" and "set" functions in all projects just to have a basic persistent k-v functionality. It was OK and had the extra benefit of allowing me to safely check this cache on a different jupyter notebook process when running longer proce...

An interview with Steve Wozniak by Jessica Livingston cured my AI anxiety

Note: there's no hidden knowledge contained in this post, it's just a reflection on how reading someone's reaction to an analogous situation changed my outlook Like everyone who works in an information job, I have been worried these last few months about how AI would impact my place in the labor force in the coming decade. Even though I didn't get to the depressed extremes we've been seeing on the Internet, I could not shake off the feeling that what I could offer to a company - no, to the whole economy, which just means "other people" - would get a lot less valuable. Come mid January, I wast taking a week off and had taken to read a few books since I read so little non-technical content on a day to day basis. One of these books was "Founders at work" by author and YC co-founder Jessica Livingston. The book is a series of interviews conducted by Jessica with the founders of some of the most important tech companies - sometimes specific products -...

What if regular exercise is the best cognitive exercise?

File this under highly speculative. I’m sure there is better research on this topic than this writing This past week, for no obvious reason, I considered a few thoughts at the same time: Exercise is supposedly one of the best anti-aging “drugs”, and also highly effective (relatively speaking) against cognitive decline There’s this vague idea that after you become “professionally inactive”, you accelerate your cognitive decline To avoid cognitive decline, one must keep “exercising the brain”, so the incentive for seniors to have hobbies, do crosswords, sudoku, etc Now, from this point it seems that I’d go to a very commonplace conclusion about how exercising is probably better than sudoku or something, and to be frank that’s exactly where I’m going. But another two things crossed my mind at the same time: Recent advances in AI, and less recent advances in computing in general showed that a lot of the things we consider “cognitively hard” - from symbolic manipulation to arithmetic, “...
