Pages that are empty without JS: dead to history (archive-org), unreliable for search results (despite any search engine claims of JS support, check it yourself), and thus ignorable. No need to waste time reading or responding. Also known as, if it’s not curlable, it’s not on…

Tiny ELF Files: Revisited in 2021
Quick edit: While I work on a proper update, I'll note here that several posters on reddit and hackernews have pointed out ways to bring the total size of the program down to 105 bytes while still printing the full "Hello, world!"

We memo all the things (2020)
On my team at Coinbase, we ask everyone to use the React performance trinity – memo, useMemo, and useCallback – all the time. For some reason, this is controversial. I’m guessing this has something to do with Twitter. This article explains why we do it anyway.
