The writer is struggling with the difference between Chinese and English language structures, which shape their perception of truth and reality. They find Chinese's "High Context" strategy of ambiguity and indirectness useful for maneuverability, but English's directness and categorization create a sense of vulnerability and self-exposure.
The user criticizes modern software naming conventions for being unclear and arbitrary, citing Richard Stallman's 2022 EmacsConf talk on the importance of descriptive names. They argue that clarity in naming is essential for respect for users' time and cognitive resources, and propose a cultural correction towards more professional standards.
The author paused their code editor Boo to work on a new programming language, driven by personal inspiration rather than commercial success. They're taking a break from Boo, but plan to return to it when they feel inspired again.
The user uses a single text file as their main productivity system, which they update daily with tasks from their calendar and notes on completed work. This system has helped them manage their workload, recall past events, and maintain control over their daily tasks for 14 years.

The Electronic Frontier Foundation has launched a resource hub to fight against age verification laws that create surveillance and censorship. These laws harm youth and adults by restricting access to information and undermining online privacy.
Our perspective is that patterns are valuable for solving specific problems, often helping to communicate comminalities in code problems for humans. If a project doesn't have those problems, there isn't a need to apply them. Patterns can also be very language or framework-specific (e.g. React), which can often mean thinking beyond the scope of just the original GoF design patterns.
Seth Larson proposes a method to make deprecated functions return wrong results occasionally, logging deprecation warnings each time. This would make delaying maintenance more expensive and immediate to users.
