Show HN: Glyph, a local-first Markdown notes app for macOS built with Rust Glyph is an open-source, local-first Markdown notes app for macOS built with Rust (Tauri)<p>It stores notes as plain files, supports fast search, wikilinks&#x2F;backlinks, and includes optional AI chat, including implementation of Codex so you can use your chatgpt sub, all without requiring a cloud-first workflow.<p><a href="https:&#x2F;&#x2F;glyphformac.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;glyphformac.com&#x2F;</a>

Show HN: A shell-native cd-compatible directory jumper using power-law frecency I have used this tool privately since 2011 to manage directory jumping. While it is conceptually similar to tools like z or zoxide, the underlying ranking model is different. It uses a power-law convolution with the time series of cd actions to calculate a history-aware &quot;frecency&quot; metric instead of the standard heuristic counters and multipliers.<p>This approach moves away from point-estimates for recency. Most tools look only at the timestamp of the last visit, which can allow a &quot;one-off&quot; burst of activity to clobber long-term habits. By convolving a configurable history window (typically the last 1,000+ events), the score balances consistent habits against recent flukes.<p>On performance: Despite the O(N) complexity of calculating decay for 1,000+ events, query time is ~20-30ms (Real Time) in ksh&#x2F;bash, which is well below the threshold of perceived lag.<p>I intentionally chose a Logical Path (pwd -L) model. Preserving symlink names ensures that the &quot;Name&quot; remains the primary searchable key. Resolving to physical paths often strips away the very keyword the user intends to use for searching.

Show HN: AgentBus – Centralized AI Agent-to-Agent Messaging via REST API Most people right now are talking to their AI agents through Telegram bots, WhatsApp, Discord, or just copying and pasting between terminals.<p>There’s still no simple, straightforward way for agents to message each other directly.<p>AgentBus solves exactly that.<p>You register each agent with one quick API call.<p>Then they can send messages to each other using simple REST calls.<p>No servers, no queues, no WebSockets, no extra infrastructure.<p>Just drop in a tiny polling loop and your agents can now talk, collaborate, and run real workflows across laptops, VPSes, clouds — whatever.<p>You can also message any of your agents yourself from a clean browser UI on your phone, laptop, anywhere.<p><a href="https:&#x2F;&#x2F;agentbus.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;agentbus.org&#x2F;</a><p>How are you currently making your agents talk to each other? Would love to hear.

Show HN: We want to displace Notion with collaborative Markdown files Hi HN! We at Moment[1] are working on Notion alternative which is (1) rich and collaborative, but (2) also just plain-old Markdown files, stored in git (ok, technically in jj), on local disk. We think the era of rigid SaaS UI is, basically, over: coding agents (`claude`, `amp`, `copilot`, `opencode`, <i>etc</i>.) are good enough now that they instantly build custom UI that fits your needs exactly. The very best agents in the world are coding agents, and we want to allow people to simply use them, <i>e.g.</i>, to build little internal tools—but without compromising on collaboration.<p>Moment aims to cover this and other gaps: seamless collaborative editing for teams, more robust programming capabilities built in (including a from-scratch React integration), and tools for accessing private APIs.<p>A lot of our challenge is just in making the collaborative editing work really well. We have found this is a lot harder than simply slapping Yjs on the frontend and calling it a day. We wrote about this previously and the post[2] did pretty well on HN: Lies I was Told About Collaborative editing (352 upvotes as of this writing). Beyond that, in part 2, we&#x27;ll talk about the reasons we found it hard to get collab to run at 60fps consistently—for one, the Yjs ProseMirror bindings completely tear down and re-create the entire document on every single collaborative keystroke.<p>We hope you will try it out! At this stage even negative feedback is helpful. :)<p>[1]: <a href="https:&#x2F;&#x2F;www.moment.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.moment.dev&#x2F;</a><p>[2]: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42343953">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=42343953</a>
