X bookmarks are where good content goes to die. No fuzzy search, no topic browsing — so I built xbm, a 100% local bookmark manager:
🔎 FTS5 + EmbeddingGemma hybrid search
🗂 3 category axes: 14,441 → 61
🌌 UMAP map, timeline, threads ledger
#LocalLLM #LocalLLaMA #RAG #Gemma
The threads ledger separates algorithm hype from your real knowledge assets:
⚠ interrupted: active 23 months, silent 4 — the feed stopped, you didn't
✓ persistent: active 44 months, spanning 13 years
🌱 new shoots · ⚡ hot pulses
#SecondBrain #SelfHosted
Timeline view: monthly topic stats across all bookmarks, as a narrative of how your focus moved.
2012 knowledge → 2020 life abroad → 2021-22 AI tooling → 2023+ "AI monetization" as the main thread.
Every node says what you turned to, and why.

Problem 2: no structure, just a timeline.
xbm slices bookmarks along 3 orthogonal axes:
📁 12 zero-shot categories
🔤 1,115 keyword clusters
🧠 27 LLM semantic clusters
Intersection = semantically close AND same wording: 14,441 → 61.
#LocalFirst #DevTools
X only matches literal words: "inference optimization" never finds the CUDA tweet that never says those words.
xbm runs two retrievers in parallel, fused with RRF:
🔤 FTS5 trigram, CJK substring match
🧠 local EmbeddingGemma cosine

My X bookmarks: 14,441 — X's own tools made them useless. One wrong character in search = zero results. Browsing by topic doesn't exist. So I built xbm: a 100% local bookmark manager. Nothing leaves your machine. 🧵 #BuildInPublic #SideProject
程序员节ZCode送了3亿Token，于是做了个工具管理X书签，以往搜索错一个字都找不到，更别说按语义相似搜索，只能一直往下翻浪费时间。
功能特点：
✅ 语义搜索:搜「推理优化」,
✅ 分类检索:通过关键词和语义条精准收窄
✅ UMAP 星云图 + 时间脉络 + 线索账本
✅ 本地 EmbeddingGemma，毫秒级搜索响应
加了个时间脉络的整理:
按月聚合全部书签的主题统计,还原你的认知轨迹: 2012 知识科普 → 2020 海外生活 → 2021-22 AI 工具萌芽 → 2023 后「AI 变现实操」成为主线。
每个节点都写明了转向了什么、为什么转向。

We’re rolling out some big improvements to Gemma 4, fueled by incredible community feedback and contributions!
Here is a breakdown of what’s being fixed and updated in this release: 🧵👇

WSL container is now available for public preview.
That means you can create, run, test, and debug Linux containers directly through WSL on Windows.
Here’s how to get started + a few ways to try it 🧵

Introducing InfiniteDiffusion, my independent paper accepted to #SIGGRAPH2026!
I have one RTX 3090 Ti. No funding, advisors, or team. By day I'm a new grad SWE at Walmart.
The paper has two main contributions:
- InfiniteDiffusion: a new approach to infinite generation with diffusion models.
- Terrain Diffusion: the world’s first learned procedural terrain generator.
Here’s why this matters, and how they are connected. 🧵
