I'm looking for folks to interview for the new app I'm working on. If you've ever needed to back up some sensitive data (passwords, crypto wallet key, "legacy planning" docs) but didn't just want to print it out and hide it then I'd love to talk to you. Just let me know here and I'll be in touch: https://formstr.app/i/keydex

nostr:npub1nstrcu63lzpjkz94djajuz2evrgu2psd66cwgc0gz0c0qazezx0q9urg5l are you still planning for another Nostr gathering this year?

Today I'm workshopping a name for my social key backup tool. (It will allow you to encrypt some data, passwords, nostr key, crypto wallet, last will and testament, etc. to a specific list of people. Each person gets an unreadable piece and they must agree to reassemble the data in case you lose it or die.) I had the idea to use the Pokedex from Pokemon as UI design inspiration for the retro/nerdy vibes. I'm thinking of the name Keydex to go with it. Thoughts, reactions?

Good read on how you can use a CRDT to manage an access control list for a group or other resource: https://p2panda.org/2025/08/27/notes-convergent-access-control-crdt.html

I am still loving Kagi.com. I don’t even use any of the advanced features, just search. Also nostr:nprofile1qqsrgyzdaheuckfksqkgxz9r6qys72zh6j46f69hyzkv4a4j4vzfj6gprkucd just straight up has a Nostr account? Rad. nostr:note15mxgz0dxxhm62rttnus96uee5nl3s92krkav7l3gpsq7lalsljzskpgt56

I'm thrilled to share that I'm receiving an OpenSats grant to work on social key backup and a new Nostr groups/communities app. I'll be building both in the open and this account will probably get filled up again with posts about that work. I think one of the primary things the world needs right now is to move our social sense-making out of big social media platforms and back into community spaces that reflect our values. I'm so blessed to have the opportunity to chip away at these social/digital problems for a while longer. My intention is always to build in solidarity with folks who need these tools most. If you're interested in using these sorts of tools and want to help - I'd love to do an interview with you! Send me a DM or reply to this note and I'll be in touch.

Good thread on some of the pain experienced by new Nostr devs, and also a good response of why things are the way they are. TLDR; Loose governance is not very meritocratic, and stronger governance is generally not either 🙃 Personally I’d love to see (maybe found?) a NIP consortium/collective/co-op some day, but I don’t think it’s time yet. nostr:note1nf2les6pzrn3c60a9nm4f82qenha032a6nrh00qerjdgxr8xu06qptgedn

I had a great time at DWeb camp last week as always. I sat on an "Open Social Web" panel as the Nostr representative and I think what I had to say about Nostr was generally well-received alongside Bluesky and Mastodon. People were mostly drawn to the loose governance and the scrappy "good enough" approach to protocol design. But, like last year, it still feels like the energy folks have for "social media" as we typically think of it has been completely sucked out of the room. Few people are interested in putting more energy into some public virtue-signaling town square. I think Nostr has an advantage over Mastodon in Bluesky in this area because it really does have the most non-microblogging experiments going on, and the protocol is the friendliest to encrypted private spaces.

The iOS 26 release date is less than a month away, and Apple is making big changes this year with the introduction of the Liquid Glass design system. I'm available for last-minute contract work to help you get your app ready. Whether you just want to make sure nothing breaks, or are looking to refresh your entire UI alongside Apple, I can help you make a smooth transition!

In the future all food will be made with a microwave, and if you can't deal with that then you need to get out of the kitchen. https://www.colincornaby.me/2025/08/in-the-future-all-food-will-be-cooked-in-a-microwave-and-if-you-cant-deal-with-that-then-you-need-to-get-out-of-the-kitchen/

I really feel like I'm missing something about Cashu. nostr:npub12rv5lskctqxxs2c8rf2zlzc7xx3qpvzs3w4etgemauy9thegr43sf485vg calls it digital cash, but you are reliant on a bank (mint) to cash out. They say it works offline, but it doesn't really because it doesn't prevent double-spending offline. This makes it a glorified IOU tracker, right? Privacy-preserving IOU tracker is cool, and a network of banks that used them would be even cooler, but calling it offline digital cash seems totally disingenuous to me. Tell me why I'm wrong? nostr:nevent1qvzqqqqqqypzq5xeflpdskqvdq4swxj59793uvdzqzc9pzatjk3nhmcg2h0js8trqywhwumn8ghj7mn0wd68ytnzd96xxmmfdejhytnnda3kjctv9uq36amnwvaz7tmwdaehgu3wvf5hgcm0d9hx2u3wwdhkx6tpdshsqgy6geae7wj44ccycc8gv6ht4l57v4knp6u0rmvyxsmdeeqh4tz6scljrjun

Yesterday I finally took the plunge and downloaded Blender and started learning how to use it. I have been #3dprinting for a while but mostly I just print designs others have created, or made a few very simple designs using TinkerCad. But I finally found a project small enough to feel manageable and the time to do it. We have a sliding barn-style door in our kitchen that our two toddlers insist on slamming shut, often while the other one is in the doorway. I decided to design a simple clamp to fit on the top to keep it from closing. Here is the evolution of the design. The first was the wrong size and just fell off, the second added a little hat to keep it from sliding off but quickly broken, so the third beefed up the thickness and infill to make it stronger. And here's a video showing how it fits on: https://blossom.lorentz.is/100f29a131c0b5c6f1baf114d46382b79fae9f7968714942315d406cecdaa466.mp4 I'm already working on a second design to toddler-proof a couple of our cabinet drawers that the regular spring locks wouldn't fit on. This may be a slippery slope.

I have been finding AI really useful for coding, but this is a good reminder that AI benchmarks are not representative of reality, and developers cannot be trusted to accurately estimate their work, even after completing it 🙃 https://bsky.app/profile/metr.org/post/3ltn3t3amms2x

Starting a thread to coordinate a test of my social-key-backup tool with nostr:npub1pmwz736ys3mfhjdld4r36xqwfc5qkz7dwxdkmfu3qqd7kucvludsrm4nu6 and nostr:npub1sq8qlc7cvwxw8a662mkcvh0em9hunkwd9a642r0s6l6urkzx3v9snyt84g
