It's always TCP_NODELAY

TCP_NODELAY is recommended for latency-sensitive distributed systems as it disables Nagle's algorithm. Nagle's algorithm, designed to improve throughput by preventing small packets, interacts poorly with delayed ACKs and can lead to unnecessary delays in data transmission.

DNSecure – a configuration tool of DoT and DoH for iOS and iPadOS

https://repository-images.githubusercontent.com/281972880/04ec9400-97ff-11eb-8961-065996ae24f6
iOS 14+, iPadOS 14+, and macOS 11+ have supported encrypted DNS (e.g. DNS-over-TLS (DoT) and DNS-over-HTTPS (DoH)), but they don't have a native UI for enabling it. To solve that, DNSecure was created. DNSecure is a configuration tool of DoT and DoH. This app uses the new DNS Settings API, so it requires iOS 14+, iPadOS 14+, or macOS 11+.

Shane Legg: Machine Super Intelligence (2008) [pdf]

This thesis explores the concept of universal artificial intelligence (AIXI) and its implications. It argues that AIXI agents can learn to perform optimally in a wide range of environments, despite having no explicit knowledge about them. The thesis also investigates the limitations of computable agents in approximating theoretical super intelligent models like AIXI. Additionally, it proposes ...
