I really liked this post. Tons of small tidbits I feel I'd only get from working in the teams they worked on. Some things I noted:
* Check out `ray` as an alternative to `multiprocessing`
* Check out `tqdm`
* Use `pdb` more
* See if fast.ai or https://jalammar.github.io/illustrated-transformer/ are worthwhile
* Prioritize the papers I read better
* _Leveraged_ index funds?
Risk-adjusted return (Sharpe)
- VTI/VOO: 0.6 to 0.8
- Leveraged S&P500 ETFs: 0.5 to 0.9
- Savings account: positive infinity
- Treasury bonds: 1.0 to 1.2
Leveraged index funds give approximately the same risk-adjusted return as passive index funds but with 2-2.5x the absolute return (eg, UPRO).
However, if you have a weak stomach (you don’t like seeing your balance drop), then leveraged ETFs are not for you.
Now, the risk (potential one-year downside) is not for everyone.
