LWN.netlinuxkernelmemorylpcFeed excerpt
Memory has always been a scarce resource in computing systems, but the problem seems to have worsened recently. In particular, the worldwide shortage of memory chips has led to a renewed focus by systems developers on reducing memory usage. During the memory-management microconference at the 2026 Linux Plumbers Conference, Will Deacon discussed one specific consumer of memory that is being re-examined: kernel stacks.

Corgi is a new terminal multiplexer for managing multiple AI coding agents with activity feeds and unified launchers.
Hacker News (front page)terminalshow-hnai-agentsFeed excerpt
Hey everyone, Inspired by Herdr, I've built an agent multiplexer that I've been using as my daily driver for a few weeks now. I think I improved on the concept in a few ways, focusing on the ergonomics I always wished I had: I show you what the agents are up to, along with a running feed of their activity. There's also a simple shortcut (F1) to go to the next unread agent. I use multiple accounts, so I've added unified launcher for Codex/Claude Code/Pi. Theres some careful ergonomics there: fast search and resume over sessions, inline usage tracking etc. Many small quality of life improvements to the terminal experience: - Links can be copied with a click, so no need to drag-select over many lines - cmd+v just pastes images (even on SSH) - images have a thumbnail preview. - Built-in CPU/Memory/GPU usage tracking, broken down by workspace I assume you have access to cheap inference (Luna/Haiku/etc). It just reuses the agents to organize things for you: what is this http link? what is this worktree about? what is each agent doing? It's small but it made my environment feel more cozy. On a personal note, I've been on a frustrating sick leave for a while now. I created Corgi to challen…
