Show HN: A Security-First Web Server in C with XSS, SQL Injection Protection https://bit.ly/3D7VY52

Show HN: A Security-First Web Server in C with XSS, SQL Injection Protection I built a high-performance web server in C that prioritizes security from the ground up. Key features: - XSS protection and SQL injection prevention built into the core - Rate limiting with IP tracking and automatic blocking - Comprehensive security headers (CSP, HSTS, CORS) - Multi-threaded architecture with connection pooling - Zero-copy file serving for performance - 100% test coverage with integration tests - Pure C99, no external dependencies beyond POSIX The goal was to create a web server that's secure by default and easy to audit (under 2000 lines of C). All security features are enabled out of the box with sensible defaults. GitHub: https://bit.ly/49sImx8 I am looking for feedback, especially on the security implementation and test coverage. The code is MIT-licensed. https://bit.ly/49sImx8 December 8, 2024 at 11:47PM

Show HN: Cut the crap – remove the AI bullshit from websites https://bit.ly/4isYmmO

Show HN: Cut the crap – remove the AI bullshit from websites I’ve spent a lot of time reading articles that promise a lot but never give me what I’m looking for. They’re full of clickbait titles, scary claims, and pointless filler. It’s frustrating, and it’s a waste of my time. So I made a tool. You give it a URL, and it tries to cut through all that noise. It gives you a shorter version of the content without all the nonsense. I built this because I’m tired of falling for the same tricks. I just want the facts, not a bunch of filler. What do you think? I’m also thinking of making a Chrome extension that does something similar—like a reader mode, but one that actually removes the crap that gets in the way of real information. Feedback welcome. https://bit.ly/4go7Lum December 8, 2024 at 11:59AM

Show HN: Random Caplocks Prank https://bit.ly/4gnwtL4

Show HN: Random Caplocks Prank I was building a program that needed to allow a user to set a hotkey but the program lives in the taskbar so there's no UI. I decided what I would do is enable the caplock key when they click "Set Hotkey" and then they can disable the caplock key (or set it to its initial state, rather) to indicate they have finished. That project is still going but I got sidetracked by the idea that I could just build a program to randomly enable the caplock key every once in a while. This isn't a program designed to calculate child malnutrition or do anything to stop genocide etc but I was able to do it in a few hours and learn some new tricks. I hope this isn't too stupid for HN. https://bit.ly/3BiZEQG November 29, 2024 at 04:12PM

Show HN: Prompt Engine – Auto pick LLMs based on your prompts https://bit.ly/4ghpC5S

Show HN: Prompt Engine – Auto pick LLMs based on your prompts Nowadays, a common AI tech stack has hundreds of different prompts running across different LLMs. Three key problems: - Choices, picking from 100s of LLMs the best LLM for that 1 prompt is gonna be challenging, you're probably not picking the most optimized LLM for a prompt you wrote. - Scaling/Upgrading, similar to choices but you want to keep consistency of your output even when models depreciate or configurations change. - Prompt management is scary, if something works, you'll never want to touch it but you should be able to without fear of everything breaking. So we launched Prompt Engine which automatically runs your prompts for you on the best LLM every single time with all the tools like internet access. You can also store prompts for reusability and caching which increases performance on every run. How it works? tldr, we built a really small model that is trained on datasets comparing 100s of LLMs that can automatically pick a model based on your prompt. Here's an article explaining the details: https://bit.ly/3VnzkM8... https://bit.ly/4iqUeUr December 6, 2024 at 01:45PM

Show HN: Data Connector – Chat with Your Database and APIs https://bit.ly/3ZFZkFh

Show HN: Data Connector – Chat with Your Database and APIs Hey HN! Wanted to share a project I have been working. Data Connector is an open source tool for interacting with Databases (Postgres, MySQL, SQLite) using natural language. Prompts are handled using a ReAct[1] agent which has access to the schema and a tool for executing queries. It also has experimental[2] support for calling APIs (OpenAPI, GraphQL) which allows for queries that can span multiple systems (Find this user's details in Clerk, etc). We have mostly been using it for managing our local development environment, but it has configurable controls for running in other environments. - Privacy Mode which never sends query results back to the LLM context, instead the result is returned to the user as JSON - Approval Mode which requires manual approval of each query before it is executed Data Connector runs within a private subnet, connects to the database and polls for new queries. There is no requirement to open traffic to the database or share credentials / connection strings. Data Connector is built using another project we are working on Inferable (also open source) which is a runtime for building and observing LLM-based agents. Would love your thoughts! [1] https://bit.ly/3OHp91f [2] We have been testing these with various schemas and are currently working on better handling for large OpenAPI specs, etc. https://bit.ly/3BhdVNM December 6, 2024 at 12:00AM

Show HN: Minimalboard – A intuitive and fast way to organize work https://bit.ly/4f4fRHx

Show HN: Minimalboard – A intuitive and fast way to organize work Hi HN! Organizing my work has always been frustrating because no tool seemed to fit my workflow. Every app I tried came with endless menus, complicated settings, and more clicking than actually working. If you've ever wrestled with Jira, you know the drill — its great for tracking an army of developers, but a tad overkill for my personal tasks. That's why I built Minimalboard. It combines the simplicity of a good old notepad with the visual organization of a Kanban board. Its sole focus is speed and intuitiveness. Just click to start editing, drag to rearrange, and everything saves automatically. It's a quick, clean workspace to jot down ideas, organize tasks, or capture information on the fly. I've been using Minimalboard privately for two years, and now I'm releasing it to see if I'm the only one with this peculiar obsession for simplicity or if others are equally struggling. Give it a spin and let me know what features you'd find useful. I'm curious to see how much functionality I can stuff in before it starts looking like, well, the tools I was trying to avoid!

Show HN: The Canada census data in a SQLite file; advice appreciated https://bit.ly/49j45Yx

Show HN: The Canada census data in a SQLite file; advice appreciated This is niche, I'll admit. I needed to look through the latest census data, but it was exported as multiple multi-gigabyte bespoke latin1-encoded CSV files. Pandas, Polars, and SQLite's CSV import tool weren't much help, so I shelved the project until recently, when I started taking a SQLite course online. I picked it up again, normalized the data, and now there's a database that can be queried through a SQL view that matches the headings in the original CSVs. I'm proud of the script I created to export the data, as well as automatically compress the artifact, make the diagrams and checksums, etc. This is my first time building up a big database, does my schema seem sane? I've been considering switching the counts from REALs to TEXT, since then SQLite's decimal extension can do exact calculations, but considering there's only one or two places after the decimal points in the data, I'm not sure if it's worth it space-wise. https://bit.ly/49DSPpT December 5, 2024 at 12:20AM
