[Database] Show HN: Prela – Purely Algebraic Relation Combinators Prela is an embedded query language based on Tarski's Algebra of Relations. Its queries are concise, clear, and fast. It is implemented by shallow embedding in a host programming language: Prela operators are regular functions in the host. The implementation follows continuation-passing style which compiles to efficient columnar execution.

[CLI Tool] Show HN: Ouijit, an open-source task and terminal manager for coding agents Hi HN, I’m working on Ouijit.<p>It’s a project and task-based terminal session manager that provides a few basic but useful tools for agent workflows:<p>- Terminal sessions in Ouijit have access to the ouijit CLI, and supported agents (Claude, Codex, Pi) can work with it out of the box to manage tasks and customize a personal development workflow<p>- Tasks live on a kanban board that supports hooks for task lifecycle events (eg. ‘Run this script when a task moves to ‘in progress’)<p>I’ve found this simple combination to be very expressive and flexible for adapting to changing workflows.<p>I made the V1 a couple months ago for fun, and have kept at it since a friend shared they had logged an 8 hour work session in it. Along the way I’ve baked in lots of what I believe are table-stakes for this type of tool, like task isolation via Git worktrees, agent working&#x2F;idle status with sound and notifications, diff&#x2F;markdown plan&#x2F;URL previews, and support for VM sandboxing using Lima.<p>It’s free and open source with no login or telemetry, so feedback is highly appreciated.<p>Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;ouijit&#x2F;ouijit" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ouijit&#x2F;ouijit</a> Website: <a href="https:&#x2F;&#x2F;ouijit.com" rel="nofollow">https:&#x2F;&#x2F;ouijit.com</a>

[CLI Tool] Show HN: Breathe CLI – Paced resonance breathing in the macOS terminal I built a terminal app that paces slow breathing at 6 breaths per minute for vagal tone training. It&#x27;s a single Python file, stdlib only, no dependencies — just run breathe and follow the bar.<p>I&#x27;m a cardiology patient (HFrEF). Slow breathing at resonance frequency is one of the few non-pharmacological interventions shown to improve cardiac vagal tone and baroreflex sensitivity (Bernardi et al., Circulation 2002; Lancet 1998). I wanted a frictionless daily habit tool — no app store, no account, no subscription, just open terminal and go.<p>Design constraints, all grounded in the clinical literature:<p>- No breath retention — Valsalva risk in cardiac patients<p>- No rapid breathing — minimum 8-second cycles<p>- Exhale ≤ 2x inhale — no evidence for extreme ratios<p>- Immediate exit, always — q or Ctrl+C restores the terminal even on crash<p>The README includes a resonance frequency measurement protocol for anyone with a chest-strap HRV monitor who wants to find their individual optimum instead of using the 6 bpm default.<p>macOS only (uses afplay for audio cues).
