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. Check Github, I develop actively. What do you expect from a calendar and scheduling tool to swMar 5, 2026 3:19 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

The near side that always faces Earth is dominated by dark flat volcanic plains called maria that create the familiar man in the moon pattern seen with the naked eye.

Show HN: TypeCrt – Zero-latency typing test in vanilla TS, no frameworkshttps://typecrt.pages.dev/Hey HN, I built TypeCrt because every typing test I tried had noticeable input lag at 150+ WPM. Monkeytype uses React. Keybr uses React. 10FastFingers feels like 2012. So I built one from scratch with vanilla TypeScript, vanilla CSS, and direct DOM manipulation — no React, no Vue, no Angular.The result: zero perceptible input latency, even at 200+ WPM.Some things I'm proud of:- CRT terminal aesthetic with 50+ themes and a visual theme creator - Adaptive practice mode ("KeyForge") that uses Markov chains to generate words targeting your weakest keys - Per-word burst speed breakdown, keystroke heatmaps, consistency tracking - Command palette (Ctrl+Shift+P), mechanical keyboard sounds, pace caret ghost - Cloud sync via Firebase, tiered analytics dashboardTech stack: TypeScript (strict) + Vanilla CSS + Vite. ~15K lines. No dependencies beyond Chart.js and Firebase.I'd genuinely love feedback from this community — especially on performance, UX, and what features would make you switch from yMar 5, 2026 9:18 AM

Show HN: Compile all your competitor research in one placehttps://intel.comsync.in/Hey HN!We built SyncIntel, an internal tool we use at Comsync [https://comsync.in/] to power our other products, and we're excited to share what we've been building.We kept running into a problem while building Comsync. 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. So we built SyncIntel, which was first used as an internal tool to power our other products, and now we're making it available to everyone.Competitor research shouldn't end at a PDF nobody reads again. SyncIntel takes it further. It discovers competitor customers, builds ideal customer profiles, finds matching prospects, and generates personalized outreach. All in one place, always up to date.Whether yoMar 5, 2026 9:09 AM

Show HN: MoatRadar – AI investment research through Warren Buffett's principleshttps://www.moatradar.com/?promo=HACKERNEWSHey HN,I’m a non-developer and this is the first app I’ve ever shipped in my life. I built it over the last few days using Claude and a lot of vibe coding.The idea came from my own investing workflow: I often look at companies through the lens of specific investors (Buffett, Lynch, Taleb, etc.). I wanted a tool that could generate investment ideas filtered through those frameworks.What the app does:You choose an investor (Buffett, Lynch, Soros, Damodaran, etc.) and an asset class (stocks, startups, crypto). The app then generates 10 opportunities and explains why that investor might find them interesting, based on their known principles.Under the hood: • Node.js server (no frameworks) • Vanilla JS frontend • GPT-4o for research / synthesis • live price data • Stripe + Google OAuth • hosted on RailwayIt’s still an experiment and I’m curious if the idea actually makes sense to other investors.You can try it here:https://www.moatradar.comHN users can get 10 free credits:https://www.moatraMar 4, 2026 11:25 PM

Show HN: FirstVibe – AI analyzes your selfie and scores your vibe in 30 secondshttps://firstvibe.app/FirstVibe is an AI selfie analyzer that gives you a "vibe check" -- a personality and impression analysis based on your photo. Upload a selfie and get an overall score, personality label, 5 category scores (attractiveness, confidence, charisma, style, approachability), celebrity lookalike, aura type, dating energy, and a set of fun predictions and personalized improvement tips.It uses Claude's Vision API to read facial expressions, body language, styling choices, and overall energy from the photo. The difference from typical face-rating apps is that it focuses on personality and vibe rather than bone structure or symmetry (though it does golden ratio and face shape analysis too). The AI analyzes things like approachability, confidence level, conversation style, and what kind of first impression you make.Technical details: Rails 8, Hotwire/Turbo for real-time result streaming, PostgreSQL with JSONB for flexible AI output storage, Solid Queue for background jobs.

Open Memory Initiative (OMI) - an open DDR4 UDIMM reference designhttps://news.ycombinator.com/item?id=47248756Hi HN! I’m building the Open Memory Initiative (OMI): a community-driven engineering project to make system memory understandable, reproducible, and independently verifiable (not performance-leading, not commercial, not “competing with vendors”).A quick clarification upfront (based on earlier feedback): yes, JEDEC DDR/DIMM standards exist, and you can build/use memory controllers. My claim isn’t that DDR is unknowable. The gap I’m trying to close is that a complete, end-to-end, publicly reproducible DIMM module implementation (with explicit constraints, bring-up steps, and publishable validation evidence including failures) is still hard to find in one place, in a form others can rebuild without NDA/proprietary dependencies.OMI v1 target (intentionally narrow):DDR4 UDIMM reference design8 GB, single rank (1R)x8 DRAM devices, non-ECC (64-bit bus)Status:Stages 5–7 are complete/frozen (architecture decisions → block decomposition → full schematic + edge pin map integrity).We’re now in StaMar 4, 2026 3:18 PM

Show HN: Agile died in a Jira board – we replaced sprints with flightshttps://news.ycombinator.com/item?id=47247408Over year ago, our engineering team ditched Scrum. Not because we read some contrarian blog post, but because we looked at our calendars and realized we spent more time talking about work than doing it. Standups that ran long. Grooming sessions nobody prepared for. Retros that concluded "we should have fewer meetings" and then we'd schedule a meeting to discuss that.We tried going process-free. That lasted a few weeks before leadership started asking "when does this ship?" and nobody had an answer.So we landed somewhere in the middle. It's called Flights - and it's not new; someone tried it back in 2021: https://simonhoiberg.medium.com/...The idea is dead simple: a project is a flight. It has a takeoff date, a landing date, and a captain who's responsible for getting it there. Tasks are crates loaded onto the flight. Team members are crew. People doing maintenance between flights are ground mechanics.That's it. No story points. No velocity charts. No burndown graphs that give everyone Mar 4, 2026 1:53 PM

Show HN: A .NET Web Framework on the Base .NET Core SDKhttps://github.com/WispFramework/WispI’ve been experimenting with building a web framework directly on top of the base .NET runtime without using the ASP.NET Web SDK.I'm calling it Wisp.The main motivation was frustration with some aspects of ASP.NET, especially the requirement to target the Web SDK instead of the base .NET SDK. That makes embedding small HTTP apps inside existing applications harder than it should be since it forces you to pollute your scope with the Web SDK.I also don't like CSHTML/Razor and wanted a more traditional templating language.Wisp is a relatively lightweight MVC framework built without any dependencies on the .NET Web SDK.Some highlights: - Runs on the base .NET SDK (no ASP.NET dependency) - Traditional MVC controllers - Dependency injection via Microsoft.Extensions.DependencyInjection - Configuration via Microsoft.Extensions.Configuration - Templating via the Fluid engine (Liquid-compatible) It's still very alpha and definitely rough around the edges, but I've already built a few small appliMar 4, 2026 10:41 AM
