the physical feel of technology makes such a difference. bitkey vs coldcard is night and day. you can immediately tell how much they cared about the craft of the object and how people would hold it and use it.

and i still think about what.cd weekly. some things just don’t leave you.
my first hardware project: an offline cashu wallet on an esp32.
generate ecash, send it to the esp32 via bluetooth, esp32 decodes the ecash into individual proofs, pick any proof and display it as a QR code for redemption.
the esp32 never touches the internet. completely airgapped. just receives tokens, holds them, and displays cashu tokens.

restraint is one of the hardest skills to master in design. know when to stop.
been working on making bitcoin payments boring. it's so much fun.
looking back at the last 2 months and realizing i was actually cooking. recap soon.
gm. freedom is its own kind of salary.
i don't read design books.
i just design things i think look cool and i want to see. sometimes i get it right, sometimes i don't.
i came up in the private tracker scene. what dot cd, waffles, btn, all of it.
i see bitcoin as a continuation of that tradition. same ethos, different medium.
sometimes you gotta break away from rigid ux psychology and embrace the chances to do small special things. your users will appreciate it.
the invisible vibe of software matters more than you think. people can feel when something was made by people who actually care.
just watched someone pay with apple pay. took 2 seconds. the guy didn't even pause the convo he was having with his friend. one motion, done.
nfc is the way. eliminate all decision points. no qr scanning, no pin entry, no fee verification, no online connection requirements.

feeling insanely bullish on cashu after today's monthly dev call.
ty you all.
fighting for my life trying to get a disposable phone numbers for cashapp. smspool, and lnvpn both aren't working. anyone got any suggestions?
an entire section on bitcoin/crypto under the fold in today's nostr:nprofile1qyt8wumn8ghj7un9d3shjtnyd968gmewwp6kytcqyqnzmgktmc2anj92gtg6qs5n70e5mt579920mdjcq689qeuj97wrze443qj . all negative headlines.
it's all so tiresome.
it came to me in a dream last night, so i just made it. 
we're halfway through nut november! 15 days left to submit your cashu project. that's plenty of time.
cashu libraries are super easy to vibe code with. you can get really nutty in 15 days. build a wallet, a mint, design some posters promoting cashu, all fair game.
https://nutnovember.org/it is deeply satisfying to design beautiful software that makes surveillance harder.
