October 2025: Linux networking, epoll and io_uring

My blog posts and notes from October 2025.

• An introduction to networking on Linux, from my systems programming course
• "Notes on epoll and io_uring"

Writing I enjoyed

• "A Database Without Dynamic Memory Allocation" by Phil Eaton (2022)
  • (Phil also hosts the NYC Systems coffee club and co-runs the NYC Systems talk series, both of which I personally recommend.)
• "Thread-Specific Data and Signal Handling in Multi-Threaded Applications" by Martin McCarthy (1997)
• Linus Torvalds's catalog of brain-dead hardware features
• "My First Contribution to Linux" by Valtteri Koskivuori
• "Technological Optimism and Appropriate Fear" by Jack Clark – "The pile of clothes on the chair is beginning to move. I am staring at it in the dark and I am sure it is coming to life."
