My brother-in-law has one arm.
Today, he came by with his wife and his kid.
While we adults were in the living room, my kid brought a toy saw.
After moving it near his uncle's remaining arm, he said, "Now you just got legs", and immediately left the room to continue playing. 😮

❓What are the lessons that the Bitcoin community can learn from the Brazilian experience with the adoption of the Pix?
After more than 1.5 years of work, I am happy to announce that I have completed a research project on this question!
Feel free to leave your comments. I am very curious about everyone's opinion.

Real state is a shitcoin.
AI and remote work will crush it in the next few decades.
Here's why:
Location flexibility: Remote working has made it less necessary for people to live near their jobs. This has led to increased interest in properties in suburban and rural areas as people seek larger homes with more outdoor space and lower living costs.
AI can help individuals find properties that match their preferences, whether they prioritize proximity to certain amenities or specific features in a home.
Market transparency: AI-powered tools and real estate websites provide buyers and sellers with more information about the market, including price trends, neighborhood data, and property history.
This transparency can lead to more informed decisions and a more efficient market.

Hofstede's cultural dimensions theory is a framework for cross-cultural psychology, developed by Geert Hofstede.
It shows the effects of a society's culture on the values of its members, and how these values relate to behavior, using a structure derived from factor analysis.

I have just asked ChatGPT “What’s the difference between the data gathered by AWstats and Google Analytics?
AWStats and Google Analytics are both tools used for tracking website statistics, but they have some key differences:
1. Data Source:
- AWStats: AWStats analyzes server log files generated by the web server. It processes data from server access logs, which record every request made to the web server.
- Google Analytics: Google Analytics uses JavaScript code embedded in web pages to collect data directly from visitors' browsers. It relies on client-side tracking, which means it collects data as users interact with the website.
2. Real-time vs. Post-Processing:
- AWStats: It processes log data after the fact, which means it provides historical data about website traffic. It's not real-time and typically updates periodically (e.g., daily).
- Google Analytics: It provides real-time data, allowing you to see website activity as it happens, including current visitors, their location, and more.
3. Depth of Analysis:
- AWStats: Provides detailed server-side statistics, including information on server response codes, bandwidth usage, and the types of files accessed.
- Google Analytics: Offers in-depth insights into user behavior, such as pageviews, session duration, bounce rates, conversion tracking, and user demographics.
4. User-Friendly Interface:
- AWStats: Typically offers a more technical interface and is often used by server administrators.
- Google Analytics: Offers a user-friendly and visually appealing interface accessible to a wider range of users, including marketers and website owners.
5. Integration and Customization:
- AWStats: Generally requires less configuration and can be set up directly within the hosting environment.
- Google Analytics: Offers extensive customization options and can be integrated with various marketing and advertising platforms.
In summary, AWStats is server-centric and provides technical server log analysis, while Google Analytics is user-centric and offers a broader range of insights about user behavior. The choice between the two depends on your specific needs, technical expertise, and whether you want real-time data or historical analysis. Many websites use both tools for a comprehensive view of their web traffic. https://image.nostr.build/bb4f67b0f58d8dbcffc76c71d4d25fa785480623a6ace28b58fccac444d8d653.jpg

“The proxied-relay approach that Nostr takes is excellent at decentralization and censorship-resistance, but one thing it doesn’t do well is protect a user’s privacy by default. Because you need to connect to many different relays to communicate with most people using Nostr today, you’ll be exposing your IP address (your unique identifier on the internet) to every relay you connect to, directly associating your IP address to your digital identity on Nostr. This could be used to connect your Nostr identity with other online activity, connect multiple Nostr identities you control together without your consent, and even give the relay operators a rough idea of where you live.”

(Consider the Microblogging use case)

2023-05-21 17:36:46

"Over the last half-century of networked computing, a pendulum has been swinging betwee client-side and server-side computing. We went from mainframes and dumb terminals to powerful desktop computers to web apps and the cloud. Perhaps we will start to see a similar pendulum in this arena as well. We’ve gone from a world in which protocols dominated to one in which centralized platforms controlled all. Moving us back toward a world where protocols are dominant over platforms could be of tremendous benefit to free speech and innovation online.
Such a move has the potential to return us to the early promise of the web: to create a place where like-minded people can connect on various topics around the globe and anyone can discover useful information on a variety of different subjects without it being polluted by abuse and disinformation. Simultaneously, it could enable greater competition and innovation on the internet, while also giving end users more control over their own data and preventing giant corporations from having too much data on any particular user.
Moving to protocols, not platforms, is an approach for free speech in the twenty-first century. Rather than relying on a “marketplace of ideas” within an individual platform—which can be hijacked by those with malicious intent—protocols could lead to a marketplace of ideals, where competition occurs to provide better services that minimize the impact of those with malicious intent, without cutting off their ability to speak entirely.
It would represent a radical change, but one that should be looked at seriously."
