In the early 1960s, Douglas Engelbart introduced the distinction between "knowledge in the world" and "knowledge in the head" in relation to computer interfaces, which Donald Norman later popularized in his book *The Psychology of Everyday Things*. "Knowledge in the world" refers to making controls visible and intuitive, allowing users to rely on recognition rather than recall, exemplified by modern drop-down menus. In contrast, "knowledge in the head" necessitates users to memorize commands and operations,

Rails 8 introduces a new "comparable" option for serialized attributes, addressing a long-standing issue where changes in serialization could trigger unnecessary database updates, even if the actual data remained unchanged. This option allows comparisons based on deserialized objects rather than their string representations, reducing the risk of phantom updates, especially important for applications syncing data with external sources or utilizing serialized configurations. The comparable option is compatible with custom serializers as well. However, guidelines on when to use or avoid the option are provided, emphasizing

Johnny's Software Lab focuses on enhancing software performance through the use of SIMD (Single Instruction, Multiple Data) functions. These functions can process multiple data elements at once, unlike traditional functions that handle single data inputs, improving efficiency. The article discusses how compilers can automatically optimize code by vectorizing loops, opting for vector functions to boost performance when processing larger data sets. It highlights the importance of declaring and defining vector functions and notes that compilers manage vectorization directives, such as OpenMP pragmas,

In July 2025, an exploration of the performance of Python 3.14's tail-calling interpreter led to the discovery that modern CPUs effectively predict indirect jumps in bytecode interpreters. This ability is enhanced in stable bytecode environments, allowing for high accuracy in dispatch predictions even in typical interpreter loops. The author delved into branch prediction mechanics, emphasizing that they are not a hardware engineer but are presenting interesting high-level concepts. Notably, while detailed information on modern CPU branch predictors is limited

Ruby 3.4 begins a gradual transition to making string literals frozen by default, with the aim of improving performance through deduplication of identical string literals. Although existing code will function as usual, developers can optionally enable deprecation warnings to prepare for this change. Notably, Ruby 3.4 introduces "chilled strings" for files lacking the frozen_string_literal pragma, which helps manage strings in a more efficient way without the need for magic comments. The transition is designed to be developer-friendly
