[CLI Tool] Show HN: ggc – A terminal-based Git CLI written in Go Hi HN,<p>I built ggc (<a href="https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc">https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc</a>), a terminal-based Git CLI tool written in Go.<p>ggc provides: - A fast interactive UI (like `fzf`) for common Git operations<p>- Traditional subcommands (e.g. `ggc add`, `ggc commit`)<p>- Git-compatible config support (`ggc config` reads from `git config`)<p>- Built-in aliases and workflow automation (e.g. `ggc addcommitpush`)<p>The goal is to improve developer productivity by combining interactive workflows with scriptable CLI operations.<p>It&#x27;s still under active development, but I&#x27;d love feedback from the community!<p>GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc">https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc</a> Demo GIF: <a href="https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc#demo">https:&#x2F;&#x2F;github.com&#x2F;bmf-san&#x2F;ggc#demo</a><p>Thanks!

[Other] Show HN: Improving RAG with chess Elo scores Hello HN,<p>I&#x27;m Ghita, co-founder of ZeroEntropy (YC W25). We build high accuracy search infrastructure for RAG and AI Agents.<p>We just released two new state-of-the-art rerankers zerank-1, and zerank-1-small. One of them is fully open-source under Apache 2.0.<p>We trained those models using a novel Elo score inspired pipeline which we describe in detail in the blog attached. In a nutshell, here is an outline of the training steps: * Collect soft preferences between pairs of documents using an ensemble of LLMs. * Fit an ELO-style rating system (Bradley-Terry) to turn pairwise comparisons into absolute per-document scores. * Normalize relevance scores across queries using a bias correction step, modeled using cross-query comparisons and solved with MLE.<p>You can try the models either through our API (<a href="https:&#x2F;&#x2F;docs.zeroentropy.dev&#x2F;models">https:&#x2F;&#x2F;docs.zeroentropy.dev&#x2F;models</a>), or via HuggingFace (<a href="https:&#x2F;&#x2F;huggingface.co&#x2F;zeroentropy&#x2F;zerank-1-small" rel="nofollow">https:&#x2F;&#x2F;huggingface.co&#x2F;zeroentropy&#x2F;zerank-1-small</a>).<p>We would love this community&#x27;s feedback on the models, and the training approach. A full technical report is also going to be released soon.<p>Thank you!

[Other] The repository provides code for running inference with the SegmentAnything Model (SAM), links for downloading the trained model checkpoints, and example notebooks that show how to use the model.

[CLI Tool] Show HN: DataRamen, a Fast SQL Explorer with Automatic Joins and Data Navigation I built DataRamen, a local-first SQL explorer that helps you get the data you need fast, without writing repetitive queries every time.<p>You run it locally from the CLI (no cloud version yet), connect your databases, and you&#x27;re ready to go. The goal is to let you explore and query data like you would in a spreadsheet: intuitive, fast, and without friction.<p>Key features:<p>- Automatic joins &amp; related data navigation: Right-click any row to instantly see related records in other tables (based on foreign keys or references).<p>- Keyboard-driven UI: Hit N to jump to a table, F to filter, and so on, it’s optimized for speed so you can go from question to insight in seconds (this point is still in progress, I find it confortable, but the goal is to make it even better).<p>- Named tabs with saved queries: Keep multiple tabs open with different queries, useful for comparing or cross-checking data. Tabs are saved, so you can get back to your queries at any time.<p>- Instant edit &amp; insert: One click to edit or add rows, no need to write full queries.<p>- Multi-DB support: Connect several databases and search across all of them.<p>- Search across all columns: Find what you need even if you don&#x27;t know the exact column.<p>If you&#x27;ve ever felt slowed down by writing the same SQL over and over just to explore your data, this might save you a ton of time. I’d love feedback or suggestions, especially from folks who wrangle data often.<p>Find more information on <a href="https:&#x2F;&#x2F;dataramen.xyz" rel="nofollow">https:&#x2F;&#x2F;dataramen.xyz</a><p>PS. don&#x27;t be harsh on the logo, I did my best :)

[Other] Show HN: Clippy – a better pbcopy for macOS that handles files properly I made clippy because pbcopy can&#x27;t do something I needed every day: copy files to paste into GUI apps. When you pbcopy &lt; image.png, you get raw bytes instead of a file that Slack or email can use.<p>Clippy fixes this:<p>- clippy report.pdf → ⌘V into any app uploads the file<p>- curl image.png | clippy → pipes become pasteable files<p>- clippy *.jpg → multiple files at once<p>- Text files still work like pbcopy<p>Technical: Direct Objective-C bindings via CGo. Copies file references (like Finder), not contents. Auto-cleans temp files. No AppleScript hacks.<p>Install: brew install neilberkman&#x2F;clippy&#x2F;clippy

[Other] Show HN: I built a dream interpreter in JavaScript, no AI, no server, just logic I built a browser-only dream interpreter that maps symbols to meaning using a custom keyword engine. No AI, no tracking, no backend it’s all deterministic logic, built with vanilla JavaScript. The idea was to see if emotional and symbolic interpretations could still feel personal without using machine learning. Dreams are parsed against a map of 300+ symbolic meanings. Everything runs locally in your browser and saves via localStorage. You can revisit old dreams, reflect on interpretations, or just explore what the system sees in your subconscious. Happy to answer questions, would love feedback!
