Insights & notes.

"There are only two hard things in Computer Science: cache invalidation and naming things."
— Phil Karlton
PostgreSQL · Performance
PostgreSQL lands async I/O & batch mode improvements
All async I/O improvements are landing in PostgreSQL 18, launching later this year — the biggest performance leap in recent versions.
  • io_uring support – faster and more efficient I/O
  • Asynchronous reads (AIO) in the buffer manager
  • Optional batch mode — optimised for small requests
  • I/O concurrency enabled on all systems
Security
OpenSSH 10.0 now uses the hybrid post-quantum algorithm mlkem768x25519-sha256 by default — safe against attacks by quantum computers.
