I would like input from you all: What consequences a normal person would have due to not caring about privacy? What spcific things could happen? The more real, common, and close to everyday reality examples the better.

What is the best REST API client testing tool? Postman? Insomnia? any other? Which one would you recommend? Open source preferably.

If I understand it correctly, any user that was awarded and accepted badges (NIP-58) can remove them from his profile by just replacing the event with kind 30008. So, it's up the clients to enable that possibility. Am I right? @Cameri🐦‍🔥 @Vitor Pamplona @jb55

What privacy focused messangers do you use normally or recommend? Which one do you think will be more used? Signal? Session? Threema? Etc..

Is it me or Nostr badges (NIP-58) are not very used? not enough interest? not many good use cases?

Hoy me acordé de esta charla técnica (pero no avanzada) que di hace más de 3 años para la ONG Bitcoin Argentina en Espacio Bitcoin. Cómo funciona Bitcoin, dónde innova, y la historia de como lo inventé (?).

Devs, what is the longest you've been debugging a problem until you understood the reason?

La imprenta fue un gran invento, pero lo verdaderamente importante es la tecnología detrás de ella. La imprenta en sí tenía su lado oscuro porque redujo las barreras para difundir ideas que eran potencialmente peligrosas para la sociedad. Sin embargo la tecnología de "Transmisión de tinta por presión" permitió innovación en diversas industrias, logrando optimizar procesos que antes eran muy costosos. Por ejemplo, grabar símbolos o dibujos sobre telas, producir tarjetas, y reproducir en masa estampas oficiales. ☝️ Así suena cuando se dice "Bitcoin no, pero la tecnología Blockchain si". La imprenta efectivamente redujo barreras para la libre circulación de ideas y conocimiento, lo que implicó una verdadera revolución. Su innovación principal no fue la "transmisión de tinta por presión" sino los tipos móviles, ideal para la (re)producción de texto. Así como la innovación de Bitcoin es ordenar temporalmente registros de forma descentralizada, ideal para la transferencia de valor digital. Ambas herramientas tecnológicas tuvieron (y tienen) un gran impacto en la humanidad, descentralizando el poder de unas pocas manos y poniéndolo al servicio de todos, en pos del progreso de la civilización.

The printing press was a great invention, but what is really important is the technology behind it. The printing press itself had its dark side because it lowered the barriers for spreading ideas that were potentially dangerous to society. However, the "Transmission of ink by pressure" technology allowed innovation in various industries, allowing the optimization of processes that were previously very expensive. For example, engraving symbols or drawings on cloth, producing cards, and reproducing official stamps on a large scale. ☝️ This is how it sounds when they say "No Bitcoin, but Blockchain technology". The printing press effectively lowered barriers to the free circulation of ideas and knowledge, which generated a true revolution. Its main innovation was not "Transmission of ink by pressure" but the movable-type, ideal for the (re)production of text. Just as the innovation of Bitcoin is to order records chronologically in a decentralized way, ideal for transfering digital value. Both technological tools had (and still have) a great impact on humanity, decentralizing power from a few hands and placing it at the service of all, in pursuit of the progress of civilization.

¡Espectacular episodio el L174 de #[0] ! 👏 Un conjunto de ejemplos y enseñanzas sobre banca, crédito, dinero, mercado, y economía. Súper didáctico y claro Ááron, y #[0] un lujo como siempre. Es largo, pero lo vale.
