Nicolas Mattia – Keep your Mac awake with caffeinate

This explains how to keep a Mac from going to sleep using a simple command

There's an AI coding approach that lets you run seriously long-running AI agents (hours, days) that ship code while you sleep. I've tried it, and I'm not going back.It's the Ralph Wiggum approach. Here it is in a nutshell:Run a coding agent with a clean slate, again and again…— Matt Pocock (@mattpocockuk) January 4, 2026

Sleep: Educational Impact and Habit Formation

In a field experiment among US university students, incentives for sleep increase both sleep and academic performance. Our primary intervention pairs bedtime reminders with morning feedback and immediate rewards for sleeping at least 7 hours on weeknights. The intervention raises the share of weeknights with 7+ hours of sleep by 26% and average sleep by 19 minutes during a 4-week treatment period, with posttreatment effects of 8 minutes. Immediate incentives outperform both delayed incentives and reminders/feedback alone during treatment but have no distinguishable impacts posttreatment. The primary intervention improves average semester course performance by 0.075–0.089 grade points, a 0.10–0.11 standard deviation increase. Our results demonstrate that incentives targeting sleep can be a cost-effective approach to improve educational outcomes.

The Mythical Agent-Month – Wes McKinney

Like a lot of people, I’ve found that AI is terrible for my sleep schedule. In the past I’d wake up briefly at 4 or 4:30 in the morning to have a sip of water or use the bathroom; now I have trouble going back to sleep. I could be doing things. Before I would get a solid 7-8 hours a night; now I’m lucky when I get 6. I’ve largely stopped fighting it: now when I’m rolling around restlessly in bed at 5:07am with ideas to feed my AI coding agents, I just get up and start my day.

Language Models Need Sleep

View recent discussion. Abstract: Transformer-based large language models are increasingly used for long-horizon tasks; however, their attention mechanism scales poorly with context length. To handle this, we study a sleep-like consolidation mechanism in which a model periodically converts recent context into persistent fast weights before clearing its key-value cache. During sleep, the model performs $N$ offline recurrent passes over the accumulated context and updates the fast weights in its state-space model (SSM) blocks through a learned local rule. During inference, this shifts extra computation to sleep while preserving the latency of wake-time prediction. We test our method on controlled synthetic tasks, including cellular automata and multi-hop graph retrieval, as well as a realistic math reasoning task, on which a regular transformer as well as SSM-attention hybrid models fail. We then show that increasing sleep duration $N$ for our models improves performance, with the largest gains on examples that require deeper reasoning.

autosuspend 11.3.0 documentation

autosuspend is a daemon that periodically suspends a system on inactivity and wakes it up again automatically in case it is needed. For this purpose, autosuspend periodically iterates a number of user-configurable activity checks, which indicate whether an activity on the host is currently present that should prevent the host from suspending. In case one of the checks indicates such activity, no action is taken and periodic checking continues. Otherwise, in case no activity can be detected, this state needs to be present for a specified amount of time before the host is suspended by autosuspend. In addition to the activity checks, wake up checks are used to determine planned future activities of the system (for instance, a TV recording or a periodic backup). In case such activities are known before suspending, autosuspend triggers a command to wake up the system automatically before the soonest activity.

How Cycling Solved Sleep | Defector

AURILLAC, France — Is the Tour de France the most competitive sleep environment in sports? “Probably, yeah,” answered Dr. Jon Greenwell, EF-Education EasyPost’s Head Doctor when I asked him. Every athlete needs to recover, though the demands on professional cyclists at the biggest race in the sport are unique. Riders have to be fresh every…

Another reason why you want an ambient memory agent is TIME. Your other coding agents understand time differently depending on who or which company writes them. Your machine however should live and breathe with you in your timeline. With Claude, I often find myself begging… pic.twitter.com/XVAvzciplY— Utkarsh (@saxenauts) May 4, 2026
