Same way to write self referential structs - use index types into the whatever arena you are using. Indexes are usually 32 bit so they are a bit faster than pointers.

If you are building one off trees such as for parsing and ast transforms, bumpalo is your friend.

In your case, you can look into generational arenas and slabs which are useful for graphs.

Continuous profiling for Linux. It uses ebpf to sample running programs and unwinds the stack, then uploads to server so you know why it look 10 seconds to process that customer’s request last Christmas. :)

That is IDE's job because images can just be embedded in markdown comments... Version controlling non-text comments seems to be an unsolved problem though.

I agree with the article you linked. Mathematical knowledge is about compression. Most if not all of these formulae are just specializations of known formulae. So the value of this approach is questionable. Generating these forms can possibly be done in a much simpler way.

To understand toxic flow you have to know adverse selection. For example, you are asked to share a pizza with your brother. You are free to split it in half however you like, and your brother gets to pick which half to take. The most fair way is to split it in half otherwise he will select adversely. Market makers job is to quote the true price of an asset by offering to buy and sell at different prices without having one side picked off more than the other. So when adverse selection occurs too often over a period of time, they will simply throw in the towel and fold, regardless of whether their opponent is bluffing or not.

In this specific case, Robinhood often have worse price than NBBO, so they get to do liquidity arbitrage in addition to the less toxic retail orderflow.
