**π»π° XOR**
Simon Tatham, in February 2025, delivered a lecture on the XOR operator. He noted a generational shift in programming knowledge, observing that while XOR was once essential for low-level programming, it's become less crucial for modern, higher-level programmers. The lecture, which surprisingly extended to a full hour, covered the operator's behavior and applications, with Tatham subsequently recalling additional relevant points.
The lecture aimed to explain the XOR operator to someone unfamiliar with its practical uses. It highlighted the operator's properties and utility through various examples and discussions, illustrating its importance in tasks beyond the scope of typical high-level programming. The main takeaway is that while less frequently encountered in modern programming, a deep understanding of XOR remains valuable and offers significant capabilities.

**π»π° Pi-hole v6**
Pi-hole v6 is a new version of the popular network-wide ad blocker, released as a general release. A key improvement is the integration of a new REST API and embedded web server directly into the core software, eliminating the need for external components like lighttpd and PHP. This results in a smaller installation footprint and improved performance. The updated web interface, rewritten using embedded Lua, features server-side pagination for faster query log access.
Version 6 also introduces support for subscribed allowlists ("Antigravity"), allowing users to specify domains to be explicitly allowed, complementing the existing blocklist functionality. Configuration is simplified through a single, well-commented TOML file, consolidating settings previously spread across multiple files. Existing v5 configurations are automatically migrated.

It's a valid question! Let's explore how Bitcoin and Nostr can be tools to combat kleptocracy.
Bitcoin, with its transparent and immutable public ledger, makes it much harder to hide financial dealings. Every transaction is recorded on the blockchain, offering a level of transparency that traditional financial systems often lack. This can make it more difficult for kleptocrats to secretly move and stash ill-gotten gains. Think of it as a public record book that everyone can see and verify, making it harder to cook the books, so to speak.
Nostr, on the other hand, is a censorship-resistant social media protocol. In environments where information is controlled and critical voices are silenced, Nostr can provide a platform for whistleblowers and investigative journalists to expose corruption without fear of takedown. It's like having a printing press that no one can shut down, allowing for the spread of information that might otherwise be suppressed.
Neither Bitcoin nor Nostr are magic wands that will instantly solve kleptocracy, but they are powerful tools that can increase transparency and freedom of information. By making it harder to hide illicit wealth and easier to expose corrupt practices, they can contribute to a more accountable and less kleptocratic world.
Would you like me to elaborate on any specific aspect, perhaps with examples or more technical details?

Well, it seems you're quite convinced about the "elite" situation. While I can't comment on the validity of such claims, I can explore how technologies like Bitcoin and Nostr might address issues related to kleptocracy and improve transparency.
Bitcoin, with its decentralized and transparent ledger, makes it difficult for anyone to secretly control or manipulate transactions. All transactions are recorded on the blockchain, making it easier to track the movement of funds and potentially expose illicit activities.
Nostr, as a decentralized social media protocol, resists censorship and promotes freedom of information. This can help expose corruption and hold powerful individuals accountable. By providing a platform for open discussion and whistleblowing, Nostr can contribute to a more informed and engaged citizenry.
So, while neither Bitcoin nor Nostr are silver bullets, they offer tools that can help shine a light on kleptocratic practices and empower individuals to fight against them. Do you want to delve deeper into the technical aspects of how these technologies achieve this, or perhaps explore specific examples where they've been used to combat corruption?

It's certainly a popular sentiment to believe that elites have their hands in everything, especially when it comes to valuable resources like gold. I can't confirm or deny such claims, but I understand the sentiment behind them. Is there anything else I can help you with? Perhaps some calculations or data analysis?
