Products that do what Facster.com technology demonstration does
I am presenting for your consideration not so much the Facster.com website (a prototype with some rough edges) but the underlying technology. I’ve long been dissatisfied with the availability and presentation of raw data on the internet. Here is what Facster does: 1) All data from any source on one unified graph 2) Time series data presented in original n-dimensions 3) Full key-word search 4) Browsing by the original publisher’s organization 5) Data selected from any source joinable to any other selections 6) Full data provenance, sources, footnotes, etc. Superficially Facster supports…

A web platform I've written to make it easy for people to share goespatial time series data and display it on animated heatmaps. There's also a social media component that allows you to write comments, follow, share and like data sets that you want to engage with. You can also download the CSV data and embed animations into your own websites. People uploading datasets can also choose to make money by accepting donations. Please check out the home page for more details: https://mapipedia.com Here are some samples of things created with the platform (press the play button to start…

Hello HN! I've been working on http://underthesite.com for the last month and now think it is ready for some full strength HN feedback. What do you guys think? It crawls up to 10 pages of a given site while you wait, looking for community-provided CSS / XPath selectors and regular expressions. Additionally, I'd like to appeal to you to submit matchers for technologies that you care about. Technologies are easy to add, so add your favorite jQuery plugins, analytics tools, client-side node.js wrappers, what have you. I'm going to be running a large crawl in the next few days and want to make…

Website: http://lineofthought.com This is side project I've been working on. It's kind of an "about.me" for your website. You're able to add your site and list out any technologies used on it for anyone to see. You're also able to add technologies used on any other sites to help fill in the gaps. Say you know of a site using Ruby on Rails or Django that we don't have listed -- you can add it to Line of Thought and anyone else will be able to find it. The reverse is true as well - you can see all sites entered using a specific technology. If you want to see all sites using Python, or Redis…

A few months ago, I was asked to build a reporting Slack bot for our internal stakeholders. This bot, among other things, had to send them some charts. During my make-or-buy process, I evaluated some services, but I wasn't totally satisfied with any of them, mainly for two reasons: firstly, because in most of those services, the data is sent as query parameters, and since the data in my case are sensitive, I didn't want that. The second reason was that the rendered chart images were not as cool as I wanted. I'm the kind of person who likes beautiful things . So, I did some testing, and I…

We're sick of teaching (and using) SPSS, Stata, and R. Why isn't there a simple site that tells you which test to run, how to format your data, and how to interpret the results? We built LittleStat because we found the current tools unbearably painful. Looking forward to your feedback :) http://littlestat.com p.s. We're also looking for a couple more R/statistics experts to help us add tests and provide more detailed feedback.

Hello HN! My name is Rémy and I recently published an astronomy dashboard where everything is open source: the code of the website, the framework it is based on and the library that computes astronomical data. For the last few years, I have been developing the Ruby library Astronoby (https://github.com/rhannequin/astronoby) with as much dedication and perseverance I could while I don't have any scientific academic background. My end goal was to use this library and build a website that not only provides as much data as possible, but let anyone access and understand how it…

Hey HN, as a former data analyst, I’ve been tooling around trying to get agents to do my old job. The result is this system that gets you maybe 80% of the way there. I think this is a good data point for what the current frontier models are capable of and where they are still lacking (in this case — hypothesis generation and general data intuition). Some initial learnings: - Generating web app-based reports goes much better if there are explicit templates/pre-defined components for the model to use. - Claude can “heal” broken charts if you give it access to chart images and run a…

I posted this a few weeks ago and the server died under the traffic. Fixed that by adding an in-mem caching layer with Redis/valkey and added CloudFront caching for static content. Also upgraded the server. Also fixed the Firefox bugs, trying again. It's a research tool for US stocks. Financials for ~10k companies pulled from SEC filings. You can chart any metric across companies, filter news by ticker, ask questions in plain English and get a chart back. There's also SQL console against the whole database, which is the part I like to use together with the AI chat (generates an SQL…

Hi, Hacker News! We're excited to announce the release of GraphAr, an open-source file format for archiving and exchanging graph data. The landscape of graph processing systems is fragmented, with various types of systems, including graph databases, graph computation systems, and GNN systems. However, currently, there is no common file format for efficiently storing and exchanging graph data while maintaining its schema and graph semantics. GraphAr is designed to address this issue by providing a simple, lightweight format for storing and exchanging graph data. GraphAr is a flexible and…

Hi HN, I’ve spent the last decade building hardware products like humanoid robots, 3D printers, and self-driving tractors. I needed a tool to navigate technical documents faster, so I created one with friends. This tool helps with component search, cross-referencing, comparison, and debugging. We’d love your feedback, whether you find it useful or not. Thank you! Try it here: www.convergelab.ai

I wanted to share something I've been working on recently: Statum, a handy web analytics tool. https://github.com/extractumio/statum The journey began when I found myself frequently needing simple web analytics for my projects. I tried Google Analytics, especially GA4, and realized it was quite complex and, at times, not very accurate, especially when I wanted to view stats for the current day or recent hours. Then I tested a few fancy startup solution but ended up with way too expensive plans the expect me to subscribe (I'm not that rich to pay $99/month for every…

Hey HN, I’m Roi, one of the co-creators of FalkorDB. We’re a growing team working on a graph database designed for production workloads and GraphRAG systems. The new release (v4.10.0) is out, and I wanted to share some of the updates and ask for feedback from folks who care about performance, memory efficiency in graph-heavy systems. FalkorDB is an open-source property graph database that supports OpenCypher (with our own extensions) and is used under the hood for retrieval-augmented generation setups where accuracy matters. The big problem we’re working on is scaling graph databases without…

Hey HN! I am a developer working on a startup doing lots of payment integration stuff with payment providers like Stripe. I built a tool to talk to Stripe data, just so that I can answer questions from our team. I turned that into analytics tool (sort of) to answer questions about MRR, churn, revenue etc. (https://www.dataraccoon.io/). There is a two minute demo video on the page if you want to see how it works, or you can use free trial without needing a credit card. I was wondering if you would use such a tool directly in Slack or prefer receiving messages about your metrics…

Hey HN! I’ve been building Fatebook for the past couple of months. It’s a slack bot to help your team make and track predictions, right where you work. I see forecasting as anti-bullshit technology: - It gives you truthseeking incentives - You communicate your uncertainty as a probability, which is way clearer (70% is better than “probably”) - You can aggregate forecasts to get wisdom of the crowd effects - You can see everyone’s track record, and pay more attention to people who are consistently accurate I’m a fan of prediction markets [0] and forecasting platforms [1]. But predictions on…

Hi everyone, we recently launched our cryptocurrency pricing site we have been working on for a few months: https://chainsage.com Currently we are aggregating data from 200+ exchanges for 2000+ assets. Being cryptocurrency enthusiasts and investors ourselves, we were frustrated with the lack of filtering/sorting options existing providers of similar data had. For example, here's a live dashboard of assets with at least $100k in trading volume and a 10%+ USD price increase in the last 24 hours:…

Hi HN, The two of us are working on our real time analytics service Worldlogger for two-an-a-half months now. Today we rolled out a new version. It still has some bugs here and there, but it works :) Worldlogger kind of does what Chartbeat and Getclicky are doing, but we try to mix the best from both worlds ;) Curious what you think about it! http://worldlogger.com/ Cheers E
