Show HN: ggc – A terminal-based Git CLI written in Go
Hi HN,<p>I built ggc (<a href="https://github.com/bmf-san/ggc">https://github.com/bmf-san/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's still under active development, but I'd love feedback from the community!<p>GitHub: <a href="https://github.com/bmf-san/ggc">https://github.com/bmf-san/ggc</a>

Show HN: MCP server for Blender that builds 3D scenes via natural language
Hi HN!<p>I built a custom MCP (Model Context Protocol) server that connects Blender to LLMs like ChatGPT, Claude, and any other llm supporting tool calling and mcps, enabling the AI to understand and control 3D scenes using natural language.<p>You can describe an entire environment like:<p>> “Create a small village with 5 huts arranged around a central bonfire, add a river flowing on the left, place a wooden bridge across it, and scatter trees randomly.”<p>And the system parses that, reasons about the scene, and builds it inside Blender — no manual modeling or scripting needed.<p>What it can do:
- Generate multi-object scenes like villages, landscapes, from a single prompt
- Understand spatial relations — e.g., “place the bridge over the river” or “add trees behind the huts”
- Create camera animations and lighting setups: “orbit around the scene at sunset lighting”
- Respond to iterative changes like: “replace all huts with stone houses” or “make the river narrower”
- Maintain object hierarchy and labels for later editing<p>Tech Stack:
- Blender Python scripting
- Node.js server running MCP
- LLM backend (OpenAI / Claude, easily swappable)<p>Demo:

<a href="https://github.com/pranav-deshmukh/blender-mcp-demo/">https://github.com/pranav-deshmukh/blender-mcp-demo/</a><p>Curious to hear thoughts from folks in 3D tooling, AI-assisted design, or dev interface design. Would you find this useful as a Blender plugin? I’m open to expanding it!<p>Please try it and give it a star on github

Show HN: Display Photos on a World Map
I had this idea where you would see realtime photos on a map, right now this is simply using cat pics, not sure where to take it from here but maybe it's useful to someone. :)<p>GitHub: <a href="https://github.com/stagas/worldsnap">https://github.com/stagas/worldsnap</a>

Show HN: OrioleDB Beta12 Features and Benchmarks
Hey HN, I'm the creator of OrioleDB, an extension for PostgreSQL that serves as a drop-in replacement for the default Heap storage engine. It is designed to address scalability bottlenecks in PostgreSQL's buffer manager and reduce the WAL, enabling better utilization of modern multi-core CPUs and high‑performance storage systems.<p>We are getting closer to GA. This release includes:<p>- An index bridge to support all indexes that Heap supports<p>- Support for rewinding recent changes in the database.<p>- Tablespaces support<p>- Fillfactor support<p>- An orioledb_tree_stat() function for space utilization statistics<p>- Support for tables with more than 32 columns.<p>We also show several performance improvements using the TPC-C benchmarks. Overall, OrioleDB is much faster than Heap, also outperforming other Postgres providers.<p>We would love more people testing OrioleDB. The fastest way to do that is to use the docker image provided:<p><pre><code> docker run -d --name orioledb -p 5432:5432 orioledb/orioledb
</code></pre>
