C++26 Shipped a SIMD Library Nobody Asked For

https://substackcdn.com/image/fetch/$s_!MTs6!,w_1456,c_limit,f_auto,q_auto:good,fl_progressive:steep/https%3A%2F%2Fsubstack-post-media.s3.amazonaws.com%2Fpublic%2Fimages%2F7ffc39a3-196d-4628-8524-7cf69915c1e2_598x226.png
The C++26 standard's std::simd library is a portable SIMD abstraction that compiles everywhere but optimizes nowhere due to its library-based approach and lack of integration with the compiler's optimizer. This results in slower performance and more complex code compared to using scalar loops or other libraries like Google's Highway, which provide better performance and more features.

Frontier AI has broken the open CTF format

The competitive format of Capture The Flag (CTF) has been fundamentally changed by the use of AI tools, making it pay-to-win and reducing the art of security to a prompt. The scoreboard no longer reflects human growth and the community is losing interest, with many top teams and players struggling to stay competitive in the current format.

Halt and Catch Fire

The phrase "Halt and Catch Fire" originated from an undocumented opcode in the Motorola 6800 that caused the processor to read memory sequentially and halt, potentially overheating. It was later generalized to describe any machine-code that causes a CPU to stop functioning.
