Show HN: Aethene – Open-source AI memory layerhttps://github.com/akhilponnada/aetheneHey HN, I'm shipping my first open-source project and I'm pretty nervous about it. Aethene is an AI memory API – it gives your AI apps persistent memory. Store conversations, extract facts automatically, search semantically, handle contradictions gracefully. It works well thank most of the memory projects available on the market currently.Why I built this: I was building AI agents and kept running into the same problem – they forget everything. Every conversation starts from zero. I wanted something that could: - Auto-extract facts from conversations (not just store raw text) - Handle "user moved from SF to NYC" without keeping both as true - Search by meaning, not just keywords - Version everything (who said what, when) Tech stack: - TypeScript + Hono (fast, edge-ready) - Convex (real-time DB + vector search) - Gemini (embeddings + extraction) What it does: # Store memory curl -X POST /v1/content -d '{"content": "User loves hiking, lives in SF"}' # Recall naturally curl -X POST /v1/reFeb 22, 2026 1:57 PM

Ask HN: How do you track 2026 AI price wars? I built a tool to helphttps://news.ycombinator.com/item?id=47110844"I built https://tokencost.is to solve a recurring headache: manually scraping dozens of provider pages just to estimate API spend for my agentic workflows.My goal was a neutral, minimalist utility in the vein of Time.is. We now track 44 models—including OpenAI, Anthropic, Google, DeepSeek, Mistral, and Cohere—with hourly updates.Key Features:Real-Time Latency: We track TTFT benchmarks (e.g., Llama 3.1 at 28ms) alongside pricing.Price Deltas: We track 24h market shifts; look for the ↑↓ indicators in the table to see how the 'AI Price War' is moving.Multimodal Calculator: Handles Text, Audio, and Video tokens in a single UI.100% Neutral: No affiliate bias or listing fees. Just raw data scraped hourly.I’m not a developer by trade, so I used an agentic workflow to build the backend and scrapers. I found that being the 'product owner' rather than the 'coder' actually helped me focus on the data integrity and the specific multimodal features I needed for my own work.I'd love to hear what otFeb 22, 2026 1:28 PM

Show HN: Pq – Simple, durable background tasks in Python using Postgreshttps://github.com/ricwo/pqAt work we were using python-rq for background tasks. It does the job for simple things, but we kept bumping into limitations. We needed to schedule tasks hours / days out and trust they'd survive a restart. We wanted periodic tasks with proper overlap control. So we built a scheduling / enqueuing system around Postgres to bring these durability capabilities to python-rq. This worked fine for a while but was trickier to reason about due to its more complicated architecture (we'd run two separate services just for getting jobs from Postgres into the rq Redis queue, plus N actual task workers).pq is a simpler approach: It's a Postgres-backed background-task library for Python, using SELECT ... FOR UPDATE SKIP LOCKED for concurrency safety. You just run your N task workers, that's it. The stuff I think is worth knowing about: - Transactional enqueueing -- you can enqueue a task inside the same DB transaction as your writes. If the transaction rolls back, the task never exists.

Ask HN: How do new blogs break the backlink–indexing loop?https://news.ycombinator.com/item?id=47110054We run a small coding blog sharing our learning experience and I keep hitting the same loop: Google won't index most of our pages because the site has no authority. Authority comes from backlinks. But nobody links to a site that doesn't show up in search results. 110+ posts and almost nothing showing up on Google. Bing has started indexing them, but Google won't budge. Google indexed us in the beginning, just a bit, then after one of their updates we were destroyed and never re-covered.We've tried long-form guides, short tutorials, long-tail keywords, competitive keywords, niche topics with zero competition. I'm not sure anymore if content is the problem.We have no noindex issues, no missing sitemaps, no crawl errors — all the basic SEO boxes are checked. Site is submitted to Search Console, PageSpeed Insights performance is good (99% desktop, 85+ mobile).We started cross-posting to Medium, Dev.to, and Hashnode but we can't even be sure that's the right path.

Ask HN: How do you test your MyBatis dynamic SQL queries?https://news.ycombinator.com/item?id=47104032(Full Disclosure: I am developing this plugin and drafting this post with the assistance of AI agents. It’s been an eye-opening experiment in how AI can help "scratch an itch" faster than ever.)I’m currently working on a project using MyBatis, and one of the biggest friction points for me is verifying dynamic SQL. Whenever I have a complex query with , , or OGNL expressions, the feedback loop is painfully slow.My current "workflow" (which I find incredibly tedious) is: 1. Copy the raw SQL from the XML mapper. 2. Manually scrub the XML tags like and . 3. Replace all #{param} placeholders with actual values, one by one. (or :param) 4. Finally, paste the cleaned-up SQL into the IDE’s database console to see if it even runs.I was surprised to find that, despite many MyBatis plugins existing, none of them seem to offer a "direct execution with parameters" feature within the IDE. I expected this to be a standard feature by now, but it feels like we’re still stuck with manual labor for query Feb 21, 2026 7:52 PM

The Reason Robotics DevOps Is Failing to Scalehttps://news.ycombinator.com/item?id=47102305In the robotics industry, the transition from manual "bespoke" workflows to standardized Continuous Integration and Continuous Deployment (CI/CD) is a critical requirement for scaling operations. Robotics CI/CD involves automating the build, testing, and distribution of software specifically for heterogeneous hardware, such as NVIDIA Jetson or other edge devices.Robotics CI/CD: Key Requirements:Hardware Software Alignment: Unlike traditional cloud CI/CD, robotics requires managing diverse hardware stacks and ensuring that software (e.g., ROS2 packages, CUDA drivers) is compatible with specific sensor and motor configurations. Edge-Native Pipelines: CI/CD must extend to the "execution layer" at the network edge to handle intermittent connectivity and bandwidth constraints. Automated Validation: Standard practices now include using simulation environments (like NVIDIA Isaac Sim) to validate code before it touches physical hardware, reducing the risk of catastrophic failure.Fleet ManagemeFeb 21, 2026 4:37 PM

Show HN: Pickle Rick Ported to Claude Code – Like a Ralph Loophttps://github.com/gregorydickson/pickle-rick-claudeThis is a port of the Pickle Rick Gemini CLI extension (itself an implementation of Geoffrey Huntley's "Ralph Wiggum" technique) for Claude Code, with one meaningful enhancement: context clearing between iterations. The core idea: a Claude Code Stop hook intercepts every session exit and blocks it, injecting a fresh prompt instead. Claude never actually stops — it just keeps working through a rigid lifecycle (PRD → ticket breakdown → per-ticket research/plan/implement/refactor) until the task is genuinely complete or a limit is hit. The problem with long loops: Claude Code compresses old conversation turns as context fills up. After enough iterations, the agent loses track of what phase it's in, which tickets are done, and what it was supposed to be building. It starts restarting from scratch. The fix: every decision: block response from the Stop hook includes a reason field with a structured session summary — current phase, iteration count, ticket checklist with status, original task,Feb 20, 2026 5:54 PM

Show HN: Prothon – docs-first Python project generator for AI developmenthttps://www.prothon.dev/Prothon is a Python project generator that scaffolds a uv-based project with eight quality tools (ruff, ty, pytest, hypothesis, mutmut, bandit, vulture, complexipy) and a documentation-driven workflow for AI coding agents.The problem it solves: AI assistants lose context between sessions and drift from your decisions as context windows fill up. Prothon addresses this with three ideas:1. A three-level doc hierarchy (SPEC, DESIGN, PATTERNS) where each level scopes a single concern and higher always overrides lower. The AI implements from these docs, not from memory. Each doc-writing step is a dedicated agent that refuses content belonging at another level.2. Automated agents that keep things consistent: one cross-checks the three docs for contradictions, one generates reference skills from live documentation for your stack, one verifies code implements what the docs describe.3. A "promise" system for execution. Before each task, the agent declares what files it will touch, success criterFeb 20, 2026 4:31 PM
