Show HN: I built an AI tool that analyzes your Discogs vinyl collectionhttps://recordsv.ltI built recordsv.lt to explore a problem I ran into as a vinyl collector: once your collection grows, Discogs is great for cataloging but not great for understanding the collection itself.Recordsv connects to Discogs and analyzes your collection using the full release metadata — not just album titles but pressings, contributors, labels, and release history. The idea is to surface patterns that are hard to see manually.Some examples: * Pressing insights – compares different pressings of the same album and highlights when the version you own might not be the best sounding or most collectible one. * Contributor networks – maps relationships between artists, producers, engineers, and labels across your collection. You often discover unexpected connections between records. * Collection analytics – shows patterns in decades, genres, labels, and recording locations across the collection. * Contextual reviews – aggregates reviews and commentary about specific releases rather than just the albuMar 5, 2026 4:51 PM

Asteroid 2024 YR4 will not impact the Moonhttps://www.esa.int/Space_Safety/Planetary_Defence/Asteroid_2024_YR4_will_not_impact_the_MoonLast year, an approximately 60 metre near-Earth object captured global attention. For a brief period, asteroid 2024 YR4 became the most dangerous asteroid discovered in the last 20 years. While an Earth impact was soon ruled out, the asteroid faded from view with a lingering 4% chance of striking the Moon on 22 December 2032.Mar 5, 2026 3:50 PM

Show HN: Msplat – 3D Gaussian Splatting training in ~90s on M4 Max, native Metalhttps://github.com/rayanht/msplatHey HN, I built msplat because I wanted to train 3DGS scenes on my Mac without pulling in torch. Most ports I came across go through autograd and hence come with ~2GB of framework overhead, which felt overkill for a pipeline that's just a few dozen GPU kernels + an optimizer.So I wrote the whole training pipeline from scratch as Metal shaders: projection, tile-based rasterization, SSIM loss, backward pass, Adam, and densification. Everything runs on the GPUmsplat trains 7k iterations of full-resolution Mip-NeRF 360 scenes in ~90s on my M4 Max. In the README I compare against gsplat's published numbers, which were measured on a TITAN RTX. Ofc these are different hardware classes, so take the wall-time comparisons with a grain of saltPython bindings are on PyPI (pip install msplat), and there are Swift bindings if you want to embed this in a native app. Happy to answer questions about any of the internalsRepo: https://github.com/rayanht/msplat (Apache 2.0)Mar 5, 2026 3:23 PM

Show HN: Tymeslot – Open-source cal.com alternative built with Elixir/Phoenixhttps://github.com/tymeslot/tymeslotHey HN, I'm Luka. I built Tymeslot — an open-source meeting scheduling platform.The existing open-source scheduling tools are functional but genuinely ugly. The booking page — the thing your clients actually see — looks like a CRUD form thrown together in an afternoon. I couldn't bring myself to send people to any of them, so I built something where the booking experience feels intentional by default.Both themes are fully customizable. Live demos here: https://tymeslot.app.Features: Google/Outlook/CalDAV calendar sync, auto-created video rooms (Google Meet, Teams, or self-hosted MiroTalk P2P), 90+ timezones, webhooks, n8n automation, embeddable widget, SSO via OIDC.Built on Elixir + Phoenix LiveView. Self-host via Docker, Cloudron, or Railway — or use the managed cloud (free tier, Pro at EUR 5/month). License is ELv2.I am happy to make this the leading open-source calendar solution over time.

Show HN: Liftstack – Snippet-level A/B testing for CRM marketershttps://www.liftstack.com/I've spent years in CRM and email marketing, and one thing has always driven me mad: the constant pressure from the business to "test everything" when you know damn well you'll never reach statistical significance.Most ESP's use frequentist models. You need a fixed sample size calculated upfront, you can't peek at results early without inflating your false positive rate, and if your list isn't massive, you're waiting weeks for a result that often comes back inconclusive anyway. So teams either ignore the statistics entirely and just pick whichever variant "looks better" after a day, or they stop testing altogether. Either way, you learn nothing.On top of that, the testing workflow itself is painful. You duplicate your entire template, change the one thing you want to test (a subject line, a hero image, a CTA), split your audience, send, and wait. Want to test two things at once? Now you need four template versions. Three things? Eight versions. It scales terribly, and most teams just dMar 5, 2026 3:18 PM

I miss the grind of writing software before AIhttps://news.ycombinator.com/item?id=47261989I learned HTML at 10, spent an entire summer figuring out how to link webpages together. At 14 I built a CNN-based security camera system for a school science fair — took months, 14-16 hour days, and I had no idea what I was doing when I started.Today I told Claude to fine-tune an LLM on my X posts. Prompt to finished model with a web UI in 30 minutes. I was impressed and unsatisfied at the same time. I achieved my goal but learned nothing — I don't even know which libraries it used.I'm not anti-AI. I use it for everything now. But the old way of writing software — the googling, the failed experiments, being stuck on a bug for days — that's where the actual learning happened. Every feature forced you to understand the codebase, read docs, weigh tradeoffs.I just wish the 14-year-old me had something left to figure out on his own.Link to the full article: https://open.substack.com/pub/princerawat/p/software-in-the-age-of-ai?r=yts8r&utm_campaign=post&utm_medium=web&showWelcomeOnShare=trueMar 5, 2026 2:36 PM

Show HN: Sanna – OpenClaw for your phone. Open-source voice AI agent for Androidhttps://github.com/sannabotdev/sannabotappI'm a dad of three, and my life is a constant context switch – school drop-offs, grocery runs, laundry, work calls, football practice. The only time I have to "manage" my life is in the car, and my hands are on the wheel. I kept reaching for Siri and Google Assistant and being let down. "Read my WhatsApp messages" – can't. "Add diapers to the shopping list" – opens a web search. These assistants are stuck in 2018.So I built Sanna, an open-source, voice-first AI assistant for Android. Inspired by what OpenClaw did for the desktop – an LLM that actually does things – but for the device in my pocket.What my morning looks like now: Kids in the car, I say "Hey Sanna": "Read me the new WhatsApp messages" – reads them aloud, I reply by voice. "Add milk and diapers to the shopping list" – done, stored locally. "What's on my calendar?" – spoken summary. "Play the latest Doppelgänger episode" – fetches RSS, downloads, plays. "Text my wife: picking up the kids at 4" – SMS sent, hands on the wheelMar 5, 2026 2:21 PM

Show HN: BidWix – one-shot price agreement using secret max/minhttps://bidwix.com/Hi HN — I built BidWix, a small negotiation tool for agreeing on a price without haggling.How it works:- The buyer enters their true maximum price (kept secret from the seller). - The seller enters their true minimum price (kept secret from the buyer). - If there is overlap, BidWix suggests a single “fair” price using the geometric mean (so the compromise is symmetric in percentage terms, not absolute currency units).Notes:- No signup. Email is optional. No ads. - BidWix stops at the price suggestion. It does not handle payment, contracts, escrow, or delivery. - It’s meant for cases where both sides want to make a deal, but don’t want the “you go first” dance. - I’m not a skilled negotiator myself, so I wanted a tool where negotiation skill is less of an advantage. - It seems to work especially well for intangible goods (I’m a sound designer).If you try it, I’d value feedback on:- Where the flow feels confusing or too wordy. - Whether the suggested price feels reasonable in real negotiMar 5, 2026 12:24 PM

Show HN: PulseTech.news – an automated, privacy-first tech aggregatorhttps://pulsetech.news/I built PulseTech.news because I was tired of "heavy" tech news sites. I wanted a lightning-fast, zero-bloat aggregator that I could check in 30 seconds to get the global pulse.Technical Highlights:* Performance: Built on a lean PHP/MySQL stack for sub-100ms page loads. No heavy frameworks, just vanilla performance. * Automation: A headless background scraper (bin/scrape.php) runs on an hourly cron cycle to digest, categorize, and deduplicate headlines from the world’s top tech sources. * Privacy-First: Implemented Google Consent Mode v2 and PII-free click tracking to be fully GDPR/CCPA compliant without compromising analytics. Semantic Web: Every listing is backed by dynamic JSON-LD ItemList schemas, making the site highly discoverable by search engines. * I’ve spent the last few days fine-tuning the automated categorization engine to ensure that "AI" news stays in AI, "Cybersecurity" stays in security, etc., based on a weighted keyword detection system.I'd love to hear your feedback Mar 5, 2026 12:11 PM

Show HN: Mnemora – Serverless memory DB for AI agents (no LLM in your CRUD path)https://github.com/mnemora-db/mnemoraHi HN,I built Mnemora because every AI agent memory solution I evaluated (Mem0, Zep, Letta) routes data through an LLM on every read and write. At scale, that means 200-500ms latency per operation, token costs on your memory layer, and a runtime dependency you don't control.Mnemora takes the opposite approach: direct database CRUD. State reads hit DynamoDB at sub-10ms. Semantic search uses pgvector with Bedrock Titan embeddings — the LLM only runs at write time to generate the embedding vector. All reads are pure database queries.Four memory types, one API: 1. Working memory: key-value state in DynamoDB (sub-10ms reads) 2. Semantic memory: vector-searchable facts in Aurora pgvector 3. Episodic memory: time-stamped event logs in S3 + DynamoDB 4. Procedural memory: rules and tool definitions (coming v0.2)Architecture: fully serverless on AWS — Aurora Serverless v2, DynamoDB on-demand, Lambda, S3. Idles at ~$1/month, scales per-request. Multi-tenant by default: each API key maps to an isoMar 5, 2026 10:41 AM

Our competitor research was scattered everywhere. We'd run deep research through Gemini, Claude, and other AI tools, read through lengthy documents, and then... lose track of everything. Important insights would disappear into browser tabs and forgotten Google Docs. We needed a dead-simple way to track competitors, their customers, and turn that intelligence into action.
