   Ray▲293

   I've been using this daily for 4 months and figured others might find it useful. This is my first open source project so would love any feedback. Ray connects to your bank via Plaid, stores everything in an encrypted local SQLite database, and lets you ask questions about your finances in natural language. No cloud, no account, your data is stored on your machine. Before anything reaches the LLM, all PII is stripped — your name, companies, transaction details are redacted and replaced with tokens, then rehydrated locally in the response. The AI never sees who you are.

    I made a simple personal finance API (like Yodlee)▲12

    It's at http://finkin.com. The goal is to allow a developer to sign up in seconds, and within minutes begin querying data. It runs under https and stores no access information. From http://news.ycombinator.com/item?id=1431583, I realized that all those types of sites are not tailored to developers like the other simple APIs around the web are (i.e. flickr). I made mine as simple as I thought possible. From http://news.ycombinator.com/item?id=1676458, I realized that eventually it should be a scalable model where you pay pennies per the # of requests you make. Right now it supports many…

    A thin Python library to access HN data using Algolia's API▲15

    Hello community. Some time ago I was trying to create a project for my students using Hacker News data. As you might know, HN offers an official API [0], but it's based on Firebase and I felt it's main usage is to build clients, rather than consult data. I found out that Algolia also provides an official REST API [1]. It's exactly what I needed: the ability to "search" HN. Either by keywords, type of stories (Show HN, Ask HN, etc) and/or date. So I created a thin python wrapper on top of Algolia's Search API: https://github.com/santiagobasulto/python-hacker-news The…
