- Oct 9, 2026 Futures as Write-Once Cells: Polling, Waking, and Cancellation The shared state inside a future, why a poll-based executor needs a waker at all, and how the same cell supports both asynchronous completion and cancellation. programming languages
- Aug 13, 2026 NAPI and Interrupt Mitigation How a network driver switches from one interrupt per packet to a budgeted poll, what the weight and time limits protect, and where the scheme loses packets. operating systems
- May 4, 2025 Interrupt Moderation and Event Delivery at High Rates Why one interrupt per completed transfer collapses at high packet rates, how coalescing timers and counters bound the damage, and what a polled-mode driver gives up. computer architecture
- Mar 13, 2025 io_uring Submission and Completion Ring Mechanics The shared-memory rings that carry requests into the kernel and results back out, how batching and polling remove syscalls, and where the cost model replaces transition overhead with memory ordering. performance engineering
- Jan 7, 2024 Cursor Columns and Where the Next Incremental Read Starts How a polling connector decides which rows are new, why a timestamp cursor loses rows at ties and clock skew, and what a composite keyset cursor fixes. data engineering
