Eliminating syscall context-switch overhead for sub-microsecond networking via DPDK or io_uring is powerful, but profile first. Often, algorithmic efficiency beats premature kernel bypassing. Measure your bottlenecks. #SystemDesign #SoftwareEngineering #Performance

seL4 is great for firmware/lowlevel
from what i seen i like the WASI for userspace (irrespective of WASM, it's a modern capability based system interface)
it could use some io_uring async no-syscall interface for super high bandwidth tasks, but for run-of-the-mill software it's getting there

Swift System 1.9.0 released
This release adds the implementation of StatFS and related types (SYS-0009), as well as support for pollAdd requests in IORing. IORing.Request.write now accepts an UnsafeBufferPointer, and the UnsafeMutableBufferPointer variant is deprecated. Errno.description now uses strerror_r/s to guarantee thread-safety. Other changes include IORing and FilePath bug fixes, and testing improvements. This release requires Swift 6.2 or later. What's Changed New features [IO_URING] Add support for pollAdd o...

USN-9002-1: Linux kernel (NVIDIA Tegra) vulnerabilities
It was discovered that the io_uring subsystem in the Linux kernel did not
properly handle canceled task work when processing certain wait operations,
leading to the operation being performed in the wrong task context. A local
attacker could possibly use this to cause a denial of service (system
crash). (CVE-2026-81010)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
