XOR'ing a register with itself is the idiom for zeroing it out. Why not sub?

Building my npx business card

Ooh, free real estate, let's colonize and gentrify package management
aabhay•11mo ago
Lmao, gentrify cracked me up
neilv•11mo ago
Do these npx business cards run arbitrary code on your computer?
cypherpunks01•11mo ago
npx

Run a command from a local or remote npm package

Description

This command allows you to run an arbitrary command from an npm package (either one installed locally, or fetched remotely), in a similar context as running it via npm run.

neilv•11mo ago
Yes, then is a "command from an npm package" arbitrary code?

And what is this "similar context as running it via npm run"?

Would it be better to answer the question directly?

joshka•11mo ago
Yeah, this seems like a very smart but inherently flawed idea.
cypherpunks01•11mo ago
Yes I agree! OSS package management ecosystems are a great idea, but allowing submissions without any review or vetting is just asking for supply chain attacks.
Xss3•11mo ago
May as well just release an executable tbh.

Terminal business cards are a nice idea, but RCE business cards are just asking for trouble. Instead of npx, what happened to good'ol curl? Something like

$ curl ashley.dev

Some decades ago, we had finger (https://en.wikipedia.org/wiki/Finger_%28protocol%29) which is designed for this very use case. Sadly it's no longer installed by default with most distros:

$ finger @ashley.dev

This would be a great advertisement for security consulting.
