React recently introduced an experimental profiler API. This page gives instructions on how to use this API in a production release of your app.

Profiling in production

React DOM automatically supports profiling in development mode for v16.5+, but since profiling adds some small additional overhead it is opt-in for production mode. This gist explains how to opt-in.

Prediction as of 3/15/2019 JST:

• Bitfinex is insolvent, for the Bitcoin economy's usual quixotic definition of insolvent.
• This happened as a result of collateralizing Tether with BTC and other cryptocurrencies during the run-up.
• Bitfinex / Tether treat whether Bitfinex held the collateral or Tether held the collateral as a material distinction, but that's ridiculous due to common control. The important fact: in 2018, ground truth diverged from "There is $1 in a bank account for every tether outstanding" to "There is $1 in a bank account and/or $1 worth of Bitcoin at prevailing prices available to Bitfinex for every tether outstanding."
• This makes Tether synthetically long Bitcoin, via a receivable from Bitfinex. Bitfinex took the newly issued Tether and then, since this accounting shellgame appears to balance its books and leave it with surplus Bitcoin, either sold or lent the Bitcoin to short sellers during the run-up.
• If Bitfinex simply sold the Bitcoin, they're doing relatively well for themselve

nature works was fascinating. Science fiction felt like a grand
adventure.

Then I started a software company and poured every ounce of energy
into it. It failed. That hurt, but that part is ok. I made a lot of
mistakes and learned from them. This experience made me much, much
