I took ChatGPT on holiday and it was like having a magic translator and tour guide in my pocket.

From translating menus to explaining art and wine, it made everything easier and more interesting.

@kisielk He says it with such gravitas too. Devastating.

@HighSheriffIOW Wonderful work there. Not me though. I don't think he's on Twitter.

COVID broke out eight miles from the world’s leading laboratory for the study of novel sarbecoviruses.

PSA: Before copy-pasting a GitHub source code link, especially one that links to a line or line range, hit `y` to make the URL include the current commit hash. That way the link will keep working even if the file is later changed or moved/deleted.

On the Ethereum Virtual Machine if you try to execute an invalid instruction it aborts your program and takes all your money ("all remaining gas is consumed"). Hardcore.
