Thanks to everyone that attended our @HRF Oslo Freedom Forum workshop. We hope you had fun and learned something! While we only had time to cover one project, Canary Bitcoin (http://canarybitcoin.com) by @Andreas. @MouxDesign (@Bitcoin Design ) made her Claude skill file publicly available for all to use 🙌 🔗

This skill file gives you the experience of a senior bitcoin UX designer at your fingertips. Simply upload it to Claude (you don't necessarily need a paid account) and it will ask you a few questions about your app. Then you will be prompted to upload some screenshots and the design review begins! It will walk you through low and high fidelity mock-ups, as well as an exploratory phase where it borrows good design from sample apps. Feel free to tweak the skill file to reference other apps. The possibilities are endless. Big thank you to @HRF for the opportunity to do this. We hope participants can take what they learned and use it to make projects more accessible to activists and other freedom fighters 🚀

Transcripts from the recent @npub1ga6s...uqm2 Dev meeting are now up on Bitcoin Transcripts:

Shoutout to the one and only @schmidty for always making sure these get uploaded 👏

Calling all freedom tech builders! We are seeking volunteers for a live design review at the Oslo Freedom Forum Making Freedom Tech Beautiful workshop. Face it. Freedom tech only matters if people can actually use it. Even the most powerful applications fall short if they feel confusing or too technical. Watch @MouxDesign of @Bitcoin Design and our very own @satsie 🇹🇭 🇱🇹 use AI to apply tried and true UX principles and draw inspiration from award winning design. Participants will leave with a Claude skill that preserves the exact process from the workshop. 𝐌𝐚𝐤𝐞 𝐲𝐨𝐮𝐫 𝐚𝐩𝐩 𝐚𝐬 𝐞𝐦𝐩𝐨𝐰𝐞𝐫𝐢𝐧𝐠 𝐚𝐬 𝐭𝐡𝐞 𝐝𝐞𝐜𝐞𝐧𝐭𝐫𝐚𝐥𝐢𝐳𝐞𝐝, 𝐜𝐞𝐧𝐬𝐨𝐫𝐬𝐡𝐢𝐩 𝐫𝐞𝐬𝐢𝐬𝐭𝐚𝐧𝐭 𝐭𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐲 𝐢𝐭 𝐢𝐬 𝐛𝐮𝐢𝐥𝐭 𝐨𝐧. Make it something individuals all over the world can understand, adopt, and rely on. Builders need not be physically present for the workshop. Priority given to projects funded by @HRF.

HELP! This little pangolin started hanging around our website. It’s been at least a month and it doesn’t look like it’s going away anytime soon. What should we name it? When we launched our new website in December this fellow quickly showed up. Now it needs a name and we want your suggestions! Reply to this thread with your best name and if it is chosen, you will win a BDP swag pack. Stickers will also be sent to honorable mentions 😉 Pangolins are solitary, curious creatures known for their armor-like scales & quiet determination. Like the best open-source contributors, they build, explore, & protect what matters. To us they represent the kind of thoughtful, persistent energy we see in bitcoin devs daily. You have 10 days, until 2/26 to share your best, most clever, and imaginative names. There is no limit to the amount of times you can enter. Let’s see those names!
