Self-Guaranteeing Promises: Securing Your Data in the Age of Shifting Tech

Companies frequently break promises. This article introduces the concept of a 'self-guaranteeing promise,' a commitment verifiable by the user, independent of trusting the company. 'File over app' is an example; users retain control and can use their files in other apps. 'Stainless steel' is another – its properties are independently testable. In contrast, terms and policies aren't self-guaranteeing; companies can change them retroactively affecting user data (e.g., Google, Zoom). A true self-guaranteeing privacy promise ensures the tool lacks access to user data in the first place. The article cautions that encoding values into governance or relying solely on open-source isn't a reliable safeguard. Choosing tools with self-guaranteeing promises helps mitigate the uncertainties of a tool's future, like business closures or acquisitions.

PHP Compile-Time Generics: A Pragmatic Compromise

Generics have long been a sought-after feature for PHP, but runtime implementation has proven incredibly difficult. The PHP Foundation team proposes a different approach: compile-time generics limited to interfaces and abstract classes. This offers most of the benefits of generics while avoiding many pitfalls. By performing type checking at compile time, it significantly improves efficiency and reduces errors. While runtime generics remain impossible with this approach, it represents a substantial improvement, warranting serious community consideration.

Faster Than memcpy: A Benchmark of Custom Memory Copying Methods

2025-08-11

While profiling, the author found that `memcpy` was a bottleneck for large binary messages. Several custom memory copy methods were implemented and benchmarked, including variations using REP MOVSB and AVX instructions (aligned, stream aligned, and stream aligned with prefetching). For small to medium sized messages, the unrolled AVX version performed best. For large messages (>1MB), the stream aligned AVX version with prefetching was fastest, but its performance on small messages was abysmal. The conclusion? `std::memcpy` offers a good balance of performance and adaptability; custom methods are unnecessary unless performance is paramount.
