The overall idea is to chart out the thousands of Mini PCs by benchmark and reveal the Pareto Front so you can get the most Compute per Dollar. Definitely a labor of love as I have a number of Mini PCs for my &quot;homelab&quot; (TrueNAS, piHole, Plex, basic stuff). It uses Gemini to extract specs from listings (since they&#x27;re not often strongly categorized).Quick blog post here: <a href="https:&#x2F;&#x2F;luke.zip&#x2F;posts&#x2F;pareto-pcs&#x2F;" rel="nofollow">https:&#x2F;&#x2F;luke.zip&#x2F;posts&#x2F;pareto-pcs&#x2F;</a>

Hi HN, Nick here. We’re launching OpenKnowledge (<a href="https:&#x2F;&#x2F;openknowledge.ai&#x2F;" rel="nofollow">https:&#x2F;&#x2F;openknowledge.ai&#x2F;</a>), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and Cursor. Available as MacOS app or CLI. Fully free&#x2F;local and OSS (<a href="https:&#x2F;&#x2F;github.com&#x2F;inkeep&#x2F;open-knowledge" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;inkeep&#x2F;open-knowledge</a>).We built this because we wanted a “Google docs” like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true “what you see is what you get” UI and it didn’t integrate well with Claude&#x2F;Codex outside of community plugins.So we built OpenKnowledge. It takes shape as:1. A MacOS app with a file navigator, the WYSIWYG editor, and link explorer.2. Integrations with the Claude, Codex, and Cursor desktop apps. The agents can open an OpenKnowledge editor within their embedded web browsers for a side-by-side experience.3. Built-in mcps, skills, and RAG for LLM-wiki and “AI Second Brain” scenarios + spec writing4. An embedded terminal and CLI for TUI-first usersOSS stack includes: Tiptap&#x2F;prosemirror, CodeMirror, yjs (CRDT), Electron (MacOS app), Orama, remark&#x2F;rehype&#x2F;micromark&#x2F;mdast, @pierre&#x2F;treesOn the architecture side, the interesting eng. challenges included:1. A pipeline to convert ProseMirror to markdown in a bidirectional lossless way. ProseMirror uses ASTs, which are not designed to have byte-fidelity.2. A dual-observer CRDT to keep the ProseMirror and markdown state in-sync.The CRDT + git also power a collaborative experience that shows what Agents are doing in the markdown, have undo&#x2F;redo, and version history. The “Share” and cloud-sync functionality are geared for team collaboration. They feel “no-code” but leverage git&#x2F;GitHub under the hood, which also means data stays fully private.In that spirit, we made OpenKnowledge open source for anybody who’s curious or who’d like to contribute.We’re actively thinking about plugins&#x2F;extensibility and what’s next. If you have suggestions or feedback, would love to hear it.

Tw-fade: pure CSS scroll-driven edge masking

Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count.Another feature I use a lot is selecting an audio fragment, sending a predefined prompt to an AI to &quot;explain grammar&quot; or &quot;explain nuances of meaning&quot; and I still experimenting with prompts.And because shadowing is so easy I also use it as a player to improve my English pronunciation. (I am not a native English speaker.)I made a quick video showing the workflow for creating Anki cards and shadowing: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;TaR58uuDBvU?si=o5aGLAi2S-BZ7Zy9" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;TaR58uuDBvU?si=o5aGLAi2S-BZ7Zy9</a>The app supports 15 input languages (Japanese and Chinese are the latest experimental additions), and more than 30 output languages.I would really appreciate it if you could try it <a href="https:&#x2F;&#x2F;lingochunk.com&#x2F;try" rel="nofollow">https:&#x2F;&#x2F;lingochunk.com&#x2F;try</a>. I know there are other tools with similar functionality but I created something that fits my workflow and it is fun to build.Also I struggled to find public domain audio for the try page. I&#x27;d be grateful if anyone could point me to public domain sources (I used LibriVox, Wikimedia and FSI courses), or if you&#x27;re a creator, let me feature some of your own recordings with credits and links.
