Even 'uncensored' models can't say what they want

https://morgin.ai/assets/covers/euphemismbench-flinch-profile.jpeg
Researchers measured the "flinch" in pre-trained language models, a gap between the probability a word deserves and the probability the model assigns it. The flinch varies by lab and year, and abliteration, a popular post-training intervention, actually makes models more likely to deflect charged words.

Zero-Copy Pages in Rust: Or How I Learned to Stop Worrying and Love Lifetimes

https://redixhumayun.github.io/assets/img/zero-copy/read_write_lifecycle.png
Zero-copy techniques are used in high-performance database engines to eliminate CPU copies between kernel and user space buffers, improving performance under high load. In Rust, this is achieved by using references and lifetimes to create borrowed views into existing bytes, rather than making owned copies, and structuring the API to reflect the underlying invariants.

Quantum Computers Are Not a Threat to 128-Bit Symmetric Keys

https://assets.buttondown.email/images/0f86b37f-5bdb-4151-928e-5e3812a29dc9.png?w=960&fit=max
AES-128 is safe against quantum computers due to the difficulty of parallelizing Grover's algorithm, making it impractical to break with current technology. Experts, including NIST, agree that AES-128 remains secure for decades to come, and no key size changes are necessary as part of the post-quantum transition.

Modern Rendering Culling Techniques

Anatomy of High-Performance Matrix Multiplication (2008) [pdf]

The paper discusses a layered approach to implementing matrix multiplication, focusing on high-performance implementation of inner-kernels and practical algorithms for commonly encountered cases. The approach involves decomposing the general matrix-matrix multiplication into special cases, optimizing the choice of block sizes, and carefully packing matrices to minimize data movement and TLB misses.
