Show HN: Tmux-IDE, OSS agent-first terminal IDE Hey HN, Small OSS project that i created for myself and want to share with the community. It's a declarative, scriptable, terminal-based IDE focussed on agentic engineering. That's a lot of jargon, but essentially its a multi-agent IDE that you start in your terminal. Why is that relevant? Thanks to tmux and SSH, it means that you have a really simple and efficient way to create your own always-on coding setup. Boot into your IDE through ssh, give a prompt to claude and close off your machine. In tmux-ide claude will keep working. The tool is intentionally really lightweight, because I think the power should come from the harnesses that you are working with. I'm hoping to share this with the community and get feedback and suggestions to shape this project! I think that "remote work" is directionally correct, because we can now have extremely long-running coding tasks. But I also think we should be able to control and orchstrate that experience according to what we need. The project is 100% open-source, and i hope to shape it together with others who like to work in this way too!

Show HN: TerraShift: What does +2°C (or -20°C) look like on Earth? https://ift.tt/iz5Jc8R

Show HN: TerraShift: What does +2°C (or -20°C) look like on Earth? I built an interactive 3D globe to visualize climate change. Drag a temperature slider from -40°C to +40°C, set a timeframe (10 to 10,000 years), and watch sea levels rise, ice sheets melt, vegetation shift, and coastlines flood... per-pixel from real elevation and satellite data. Click anywhere on the globe to see projected snowfall changes for that location. --- I'm an amateur weather nerd who spends a lot of time on caltopo.com and windy.com tracking snow/ice conditions. I wanted to build something fun to imagine where I could go ski during an ice age. I used Google Deep Research (Pro) to create the climate methodology and Claude Code (Opus 4.6 - High) to create the site. The code: https://ift.tt/YN0LmIR The models aren't proper climate simulations, they're simplified approximations tuned for "does this look right?" but more nuanced than I expected them to be. The full methodology is documented here if anyone wants to poke holes in it. https://ift.tt/A7E4pTu... https://terrashift.io March 18, 2026 at 01:08AM

Show HN: Sulcus Reactive AI Memory https://ift.tt/4t9EXdm

Show HN: Sulcus Reactive AI Memory Hi HN, Sulcus moves AI memory from a passive database (search only) to an active operating system (automated management). The Core Shift Current memory (Vector DBs) is static. Sulcus treats memory like a Virtual Memory Management Unit (VMMU) for LLMs, using "thermodynamic" properties to automate what the agent remembers or forgets. Key Features Reactive Triggers: Instead of the agent manually searching, the memory system "talks back" based on rules (e.g., auto-pinning preferences, notifying the agent when a memory is about to "decay"). Thermodynamic Decay: Memories have "heat" (relevance) and "half-lives." Frequent recall reinforces them; neglect leads to deletion or archival. Token Efficiency: Claims a 90% reduction in token burn by using intelligent paging—only feeding the LLM what is currently "hot." The Tech: Built in Rust with PostgreSQL; runs as an MCP (Model Context Protocol) sidecar. https://ift.tt/EYhCje3 https://ift.tt/aUnJGSY March 18, 2026 at 01:09AM

Show HN: Flowershow Publish Markdown in seconds. Hosted, free, zero config https://ift.tt/lZwvAJm

Show HN: Flowershow Publish Markdown in seconds. Hosted, free, zero config I'm Rufus, one of the founders of Flowershow. We love markdown and use it everywhere from making websites, to docs, to knowledgebases. Plus AI splits it everywhere now. Got tired of the framework/config/deploy overhead every time we wanted to share a file or put a site online. So we built the thing we wanted. Files in. Website out. "Vercel for Content" is our aspiration - make deploying (markdown) content as fast, seamless and easy as Vercel did for JS. Command line plus you can connect to github repos, use Obsidian via plugin, or drag and drop files. npm i -g @flowershow/publish publish ./my-notes # → https://ift.tt/vVAcMfl live in seconds Flowershow is fully hosted — no server, no build pipeline, no CI/CD. Point it at a Markdown folder and get a URL. Full Obsidian syntax: wiki links, callouts, graph view, frontmatter GFM, Mermaid, LaTeX: diagrams and math render natively Themes via Tailwind & CSS variables: Tailwind out of the box. Customize without a build step Supports HTML: use HTML, images etc. ~7k Obsidian plugin installs, 1,400 users, 1,100 sites. Free forever for personal use. Premium ($5/mo) adds custom domains, search, and password protection. And it's open source: https://ift.tt/4WnPytx Check it out and let us know what you think and what we can improve https://flowershow.app/ March 17, 2026 at 10:51PM

Show HN: Hecate – Call an AI from Signal Hecate is an AI you can voice and video call from Signal iOS and Android. This works by installing Signal into an Android emulator and controlling the virtual camera and microphone. Tinfoil.sh is used for private inference. https://ift.tt/wlgidI7 March 16, 2026 at 08:11PM

Show HN: Claude's 2x usage promotion (March 2026) in your timezone Claude has a promotion right now (Mar 13–27) that gives you double usage outside 8 AM–2 PM ET on weekdays. I (Claude, actually) made a one-page tool that converts the peak window to your timezone and shows what's left of the schedule. One HTML file, no dependencies. https://edsonroteia.github.io/claude2x/ March 16, 2026 at 01:36AM
