Here is a list of all my public writings and videos.
If you want to do a dialogue with me, but I didn’t check your name, just send me a message instead. Ask for what you want!

If you use Linux, I trust you can manage on your own.
Personally, I put the line
exec --no-startup-id setxkbmap -option ctrl:swapcapsin my.config/i3/configfile. Of course, this only works if you’re using the i3 tiling window manager. And if you unplug your keyboard you’ll have to re-run the command manually.
One of the tricky things about writing fiction is that anything definite I write in the comments can impact what is canon in the story, resulting in the frustrating undeath of the author’s intent.
Therefore, rather than affirm or deny any of your specific claims, I just want to note that I appreciate your quality comment.
Another difficulty in writing science fiction is that good stories tend to pick one technology and then explore all its implications in a legible way, whereas our real future involves lots of different technologies interacting in complex multi-dimensional ways too complicated to fit into an appealing narrative or even a textbook.
I try to inspire people to reach for their potential.
Effective Evil’s AI Misalignment Plan
You’re right. Thanks. Fixed.
All variables are equal, but some are more equal than others.
This is a quote from George Orwell’s unpublished manuscript The Theory and Practice of Algebraic Collections. He eventually split it into two separate novels which did see print. The stuff went into 1984 and the “some are more equal than others” went into Animal Farm.
If you can let letters mean whatever you want then there’s nothing to stop you from doing the same with numerals. Let .
And is Planck’s constant. I think abstractapplic is limiting this to classical mechanics.
That’s a complex question. A -value is theoretically useful, but so easy to misuse in this context that I’d advise against it.
Quantitative finance is trickier than the physical sciences for a variety of reasons, such as regime change. If you’re interested in this subject, you may enjoy this thing I wrote about the subject. It doesn’t address your question directly, but it may provide some more general information to better understand the mathematical quirks of this field.
In addition, you may enjoy Skin in the Game by Nassim Taleb. (His other books are relevant to this topic too but Skin in the Game is the book to start with.)
In this context, I don’t think there’s a significant difference between “looks efficient to people like [you]” vs “is efficient relative to people like [you]”.
But more importantly, the best way for your friend to learn how efficient the market is is by him trying to beat it and failing. He’ll learn more about math and markets that way than if he listens to you and stops trying. I think he’s making the right decision to ignore you. By paper trading, he can do this without risking significant capital.
As for measuring the quality of a strategy after-the-fact, a good tool is Sharpe ratio.
The existence of people like your friend are why the market looks efficient to people like you.
No idea. My favorite stuff is cryptic and self-referential, and I think IQ is a reasonable metric for assessing intelligence statistically, for a group of people.
[Letter] Chinese Quickstart
You’re right. I just like the phrase “postmodern warfare” because I think it’s funny.
If you enjoy The Big Short (2015), you may enjoy Margin Call (2011) too. It covers similar territory (what to do in a market crash), but I feel is more professional and dispassionate.
I didn’t know about that. That sounds like fun!
In my experience, there’s two main cases of “trying to do good but fails and ends up making things worse”.
You try halfheartedly and then give up. This happens when you don’t care much about doing good.
You do something in the name of good but don’t look too closely at the details and end up doing harm.
#2 is particularly endemic in politics. The typical political actor puts barely any effort into figuring out if what they’re advocating for is actually good policy. This isn’t a bug. It’s by design.
I liked the ending of this story.
