Fun with C++26 reflection - Keyword Arguments
In this blog post, we’ll explore implementing order-independent keyword arguments for C++ through use of C++26’s proposed reflection features. I stumbled upon this technique while experimenting with reflection a few days ago and thought it might be worthwhile…

OpenSSL 3.3，3.4 中的 AES CTR 实现中的寄存器恢复代码有一处 typo，破坏了上下文，可能导致各种运行时问题
Debian[1][2] 和 PostgreSQL[3] 有开发者分别独立发现了该问题
应当 backport OpenSSL commit 5261f3c ("Restore correct registers in aarch64 AES-CTR code")（已合并至 OpenSSL master）以修复该问题。 其将被包含在将在 Feb. 11th, 2025 到来的 3.4.1，3.3.3 安全更新中[4]。该更新修复的最严重的安全问题评级为"High"。

rand_new_drbg() clobbers d15 on Graviton/armv8 · Issue #26466 · openssl/openssl
I don't particularly have a reproducer handy right now that's easy to approach; the apt code is quite complex. Recent fixes in gcc made it use the d15 register in apt code, and OpenSSL on a...
