You want to express a function that consumes an object without running its destructor. The C++ specification lacks a way to do this directly, requiring manual memory management with placement-new and std::destroy_at.

https://daniel.mitterdorfer.name/img/20240130/original-lttb-1024.png
The Largest-Triangle-Three-Buckets (LTTB) algorithm reduces data volume while preserving visual properties by selecting significant points from equally sized buckets. It can be used for downsampling time series data, but may introduce distortion in the frequency domain.

Kyber vs. RSA-2048

https://blog.ellipticc.com/_astro/kyber-rsa.BevmPzYv_1KprK.webp
RSA-2048 and elliptic-curve cryptography are vulnerable to quantum computers using Shor's algorithm, but Kyber is immune and already standardized, fast, and shipping. Kyber is dramatically faster than RSA-2048 for key generation and private operations, making it a better choice for securing digital infrastructure against future quantum threats.
