Last Notes npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc You could lose 2 keys, but I mean I make too many typos for a password. If you don't believe me or don't get it, check out all the misspelled words I have on nostr. ☺️ npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc What do you mean by if? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc An actual retirement attack? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I forgot all about that guy. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Thanks. Good ro know. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This turned out to be good advice, but I'm not sure dice alone is good enough anymore. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Part of the problem, but not the whole problem. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc NVK published an article on the raspi vulnerabilities a couple weeks ago. Those arguments are still valid, but moot when compared to bad entropy. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Heartbreaking. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Jeez. I tried bitkey with a small amount, but I couldn't load the wallet in another device and decided against using it because of this. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Agreed. 12 BIP39 words minimum and that entropy should be generated differently than your seed, eg. Coin flips instead of dice rolls. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Tap signer and Satacard are apparently unaffected according to this vibe coded website, but I have not verified this yet. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Oh I'm not using hex dice to generate keys. That's a good point. My plan is to use them as a visual way to describe Bitcoin mining. I forgot to mention that. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Fair. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I've been working on a book about self custody, but I don't intend to recommend any hardware wallets. I am going to show different ways of generating entropy without an RNG. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I used to feel the same, but this situation changed my mind. People who push the easy button are better off letting an insurance company generate their keys. There's a privacy risk, but that's better than the risk of low entropy. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Yep npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Step down as CEO. I mean this is like a hack from a dystopian novel. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc 😳 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc The motto is don't trust verify. I thought everyone used tails to test this stuff. I guess not. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc That's awesome. I had the same idea, but a pull request for that is above my pay grade. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc @nprofile…u02p mentioned adding entropy before letting people push the RNG button. I think that's the right way to look at it, a UX issue. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I've been trying to write a guide to mitigate this risk for years. I'm still working on it, but it's hard as fuck to explain it to a general audience. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Thank you for posting. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc The thing that annoys me about Twitter is the algorithms nudge people into talking about AI breaking quantum cryptography, but they don't promote tweets about entropy. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc That makes sense. Back in the day Andreas called Bitcoin programmable money so I've always looked at it as such. I think the CBDC's changed the narrative. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc There is nothing wrong with programming your own Bitcoin (eg. time locks). npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Bitcoin is programmable money. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I understand, but suspect most people trust google more than the wierd autistic Bitcoin/nostr hackers. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc 😂 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Screenshots of text annoy me, especially when it's something I would rather copy and paste like an address or something. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This one time, my aunt told me she sent me an email. I couldn't find it in my inbox or spam folder. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Sweet! npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Stable coins are clearly digital slavery beads backed by national debt. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I'm not gay, but I've studied history. Historically speaking, this is a bad idea. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc https://npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0.blossom.band/52acfa3dfdfb82a2237300d1c498076d14c63f62935b22f0009daede5456a01c.jpg npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Lol. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I like Divine because it's not just ride or die freaks. Does that count as other stuff? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I'm thinking about making this my new profile pic. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This looks interesting. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I have about $525 in USD reserves. 😂 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Buy a cheeseburger with sats npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Steak N Shake looks like the change in the world I want to see. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc True. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This is a good one. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Fun times. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Exactly. Prohibition never works, but governments never stop trying. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Good morning. I didn't realize bitchat has so many stars on GitHub. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Good morning. May someone please send me an invite code for a buzz private community? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Running Buzz npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Is this a paid platform? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Where can I find this information? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Same. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc That's wild. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Thank you. 😊 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This is the most accurate description of the economic policy of the USA since 1971. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc "Let an agent triage a bug without giving it the keys to the kingdom. Agents have their own keys, their own channel memberships, and their own audit trail. Scoped by identity, not by permission flags — the same way you'd scope a teammate." npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc What is the z index and blur? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc My kid printed a box opener with his 3 D printer. It works great, but I haven't tried a spoon. 😂 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Before the lightning network existed, I used to send Dan Carlin "a buck a show" using Bitcoin on-chain. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I'm using it because I 've been reading a lot of marketing books and busking on the Internet requires a large audience. After seeing how many people are on nostr are amy given time of day, I decided I needed to go dip in and out of the Matrix to build an audience. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc The dark wallet was killingy battery. It's unfortunate because other than that issue it's my favorite twitter clone. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc It's important to know when you are not good at something too. If you think you are great when you suck, you'll never learn. You can improve, but first you need to be honest enough with yourself to get better. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I don't like calling people dictators because it comes with too much baggage. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Awesome. I like that dude. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Gm npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Thanks you for sharing. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Thanks. That's interesting. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I find Numo fascinating because it can forward says to your own node once it reaches a certain threshold., say 100,000 sats or whatever. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Good morning. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Maybe I'm just an old, grumpy man now, but I'm concerned with the amount of teenage drivers I see laughing at their phones on the road. It's one thing to waste your life away on your couch, but that puts other people's lives in danger. That's nuts. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Ice seen this coffee cup too many times to count. I had no idea it was signed. Who made it? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Did you draw this? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc How does that work? Do you write music, lyrics, both? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This is one of the coolest parts about nostr few people understand. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc https://npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0.blossom.band/52e4ea9145ab6edbcef2520d18634a601e6d36e55773112044b6d70efba97854.jpg npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I bet it's good. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc **Earn more than you spend** is more realistic. To be honest, Saylor is still kind of a Noob so I'm not too mad that he used to say "never sell." npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Got it. Thanks. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I don't really pay. Much attention to politicians, but I'm not surprised. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Thanks.. a Buddy of mine began making bolt cards, but I wasn't sure if I could get it to work. Now I have an option. 🤔 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I could see that. I know this is a little weird, but as a teenager, my favorite snack was American cheese on a graham cracker. 😋 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Is that the dude with a brother who works for CNN that had some sex scandal? npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc She did. They were invited to the show because they made the local brea. The team made it to the second round so that was neat. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc My niece was on a dance team that went on American Idol. She rehearsed a ton. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I think this is an often overlooked aspect of the current economic situation. Tech made a lot of door dash jobs, but eliminated way more jobs. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I feel like I'm pretty good at using technology until it's time to troubleshoot my 2D printer. As it turns out, I'm an idiot. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Okay. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc A cashu payment terminal app @nprofile…afdc built. https://numopay.org/ npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I was one of those purists for a while until I realized it is impossible for everyone to control a UTXO. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Does it work with numo? I mean, I don't expect to see it in the wild any time soon, but it would be fun to try it on an old phone. 🤔 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Public Key Infrastructure, sorry. 😳 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc That one works for me. I have also been able to use the phone app, but not the other various payment terminal styles. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Congratulations! 💐 npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Congratulations. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I know what you mean intellectualky, but it'd difficult to "un-train" myself. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc This is interesting. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Yeah so that's great for PKI like nostr. Block space is scarce though. We can only do so many UTXO's per minute. npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc I changed the logo on my website and added a lightning message board that I got from @nprofile…m7rj . npub1marc26z8nh3xkj5rcx7ufkatvx6ueqhp5vfw9v5teq26z254renshtf3g0 Marc Someone tried my tip jar!
