[$] Filtering fanotify events with BPF
Linux systems can have large filesystems; trying to keep up with the
stream of
fanotify filesystem-monitoring notifications for them can be a struggle.
Fanotify is one of a few ways to monitor accesses to filesystems provided by the kernel.
Song Liu led a discussion
on how to improve in-kernel filtering of fanotify events to a joint
session of the filesystem and BPF tracks at the 2025 Linux Storage, Filesystem,

[$] Improving FUSE writeback performance
In a combined filesystem and memory-management session at
the 2025 Linux Storage, Filesystem, Memory
Management, and BPF Summit (LSFMM+BPF), Joanne Koong led a discussion on
improving the writeback performance for the Filesystem in\
Userspace (FUSE) layer. Writeback is how data that is written to the
filesystem is actually flushed to the disk; it is the process of writing
dirty pages from the page cache to storage. The current FUSE

Securing Model Context Protocol: Safer Agentic AI with Containers
Model Context Protocol (MCP) tools remain primarily in the hands of early adopters, but broader adoption is accelerating. Alongside this growth, MCP security concerns are becoming more urgent. By increasing agent autonomy, MCP tools introduce new risks related to misalignment between agent behavior and user expectations and uncontrolled execution. These systems also present a novel… ⌘ Read more

rewritten version of AUTOSEL for those who would like to play with it.

Unlike the previous version that relied on word statistics and
older neural network techniques, AUTOSEL leverages modern large
language models and embedding technology to provide significantly

10 Things Humans Are Weirdly Bad at Predicting
Humans like to think of themselves as rational, forward-looking creatures. But when it comes to forecasting the future—even our own—we’re often laughably wrong. From personal choices to global crises, our brains are wired with cognitive shortcuts and emotional biases that lead us to consistently underestimate, overestimate, or misjudge reality. Sometimes, the error is small. Other […]

如何在 Go 中設計並公開接口
Go 語言中的接口(interface)是其最具特色的功能之一。與許多其他語言不同,在 Go 中,類型不需要顯式聲明實現某個接口。只要一個類型定義了接口所需的方法,它就自動實現了該接口。然而,編寫良好的接口並不容易。不恰當地暴露寬泛或不必要的接口,容易污染包的 API。本文將解釋現有接口設計準則背後的邏輯,並結合標準庫中的示例進行說明。「接口越大,抽象越弱」大型接口往往難以找到多個實現類型。因此, ⌘ Read more
