@r0ckstardev @TheBitcoinConf @DavidFBailey @BranBTC I missed the announcement and wow, that’s quite an upgrade from previous years! Thank you! 🧡

@knorrium @TheBitcoinConf @DavidFBailey Yes, the program was announced a week ago. Seems me and @BranBTC need to write more posts about it 💪 x.com/i/status/20285…

📣 BREAKING: THE B26 WHALE PASS JUST GOT AN UPGRADE! IT'S NO LONGER JUST A CONFERENCE TICKET... ITS A NETWORK WITH ACCESS TO A YEAR ROUND PRIVATE SUPPER CLUB AND PERKS 🍽️🎟️

@thiagoghisi @GergelyOrosz Ficas até quando?

Good morning, San Francisco! Here for the very first Pragmatic Summit by @GergelyOrosz — and my first time back in the city in 6!years. Since before the pandemic. Crazy! There's something about being here in the Bay Area. The energy. The density of people tinkering and hacking things. Nothing quite beats being at the mecca, especially at these AI times. Excited to learn, connect, and see what others are thinking & building these days. P.S: photos from my early morning walk around today.

@callebtc wow this is amazing! I wish I had this idea when working @TheTileApp - sadly we only had faraday cages and robots

People in the real world move so I gave them basic path-finding skills and put them in a city block. Using data from OpenStreetMaps, I can now set up different environments and test crowds in them with just a few clicks. Here you see 140 simulated users around Time Square. Messages propagate through the entire square.

bitchat-sim – a simulated physical world for bitchat Testing a decentralized mesh-based messenger like bitchat is hard. Like, really really hard. Predicting how design decisions will affect real-world behavior in larger crowds is vital though. That's why I built a simulator.

Returning items from Amazon is easy, just scan the QR code at any UPS store

@r0ckstardev @BtcpayServer definitely. There are only 21 C# developers out there.

If I create a video tutorial on how to vibe code @BtcpayServer plugins with AI, would you watch it?

Bitchat feels like magic during flights

@umbrel will there be a migration tool eventually? I have two Pi nodes to upgrade

@knorrium 😔 all 1TB drives come to an end...

Thank you for your service, 1tb Umbrel node 🫡

@lorenzolfm E a @usebipa reporta cada transação de satsback pra receita?

Usar meu Bitcoin como garantia pra ter crédito e ainda ganhar satsback por cada compra que eu faço? Gostoso demais ☺️

Sell the rumor, sell the news I guess

i'm jason huggins, it's september 12, 2025, and linkedin has frozen my account for 24 hours for suspected bot activity. this is my story. youtu.be/Mzh6DIa989A

@PortlandHODL @r0ckstardev You can just review the code for correctness but not actually check out and test it. It’s almost a yoloAck.

@r0ckstardev Serious question, doesn't Ack include tAck? As to Ack you would need to have reviewed and tested the code?

Believing that you must act, or else Bitcoin will die, is the core symptom of Bitcoin Derangement Syndrome. Follow what you passionately believe in, but don’t let it consume you. And if you need reassurance that not giving in to emotions is the right path, just look at the history of everyone who fell to BDS (Roger Ver probably being the most famous example). In the long run, it's far better to focus on your proof of work than on "fixing" what others are doing.

Would you wear this t-shirt?

@Rob1Ham @JRiccardiPage @River @Leishman It won’t even let you buy for $1M Not bullish enough

@JRiccardiPage @River @Leishman There is a bug in the app, bitcoin isn’t $1,000,000 per coin.

At @River we pride ourselves on shipping with high quality. But if you want to take a moment to try to test the app and find any long-tail bugs or edge cases @Leishman is the engineering oncall for the holiday and will have to personally fix anything broken.

@winterrose Some things to think about: What generation(s) are you interested in? Where do you want to play (portable or at home)? Portables vary in form, size, and power. If at home, do you want to play on a big modern tv? You may want to buy an upscaler or go with FPGA devices.

@winterrose Is there something you are particularly nostalgic about? Do you want to be this guy? medium.com/message/playin…

k which of you nerds are into retro gaming? I’ve fallen into the rabbit hole

@winterrose Retro games became very expensive during Covid. A brand new 3DS used to cost around $100-$150 brand new, now it’s almost twice as much. You can look up your favorites here and see how much you are willing to pay for a game pricecharting.com/category/video…

@knorrium also whether it’s worth it for me to start collecting og game cartridges
