Products that do what GAE/Bingo, A/Bingo split testing for App Engine & Khan Academy does
We just open sourced GAE/Bingo, a re-imagining of patio11's A/Bingo for use in App Engine (w/ his approval). The lib was built for Khan Academy, where it's currently serving up A/B tests at a few hundred requests/second w/ minimal page load drag. It should get anyone on App Engine (python) up and running and A/B testing in minutes -- if you have trouble please let me know. Does its best to maintain identities as users transition from anonymous to logged-in, persists experiment results to the datastore in the background, etc.…

I decided I wanted to roll my own AB testing app for Django (https://github.com/crobertsbmw/RobertsAB) when I was finished, I came across this: http://stevehanov.ca/blog/index.php?id=132 Which is a very convincing article on why AB testing sucks and with a few extra lines, you can improve your algorithm to select the best test so you never go back and update your code (yeah right.) I then thought, how many tests does this thing have to run to truly figure out which is best? I made 4 tests with probability of success equalling 1/2, 1/4,…

Hey HN. I've just launched my very first webappp and would love your feedback. http://www.7bks.com It's a book list sharing website - kind of like playlists for bookworms. The site is built on pyton/appengine - and I learned to code in under 4 weeks to build the site. There's more details on the background of the site here: http://www.7bks.com/blog/179001 I've also published the full Python code for the site here: https://gist.github.com/670034 Feedback is really important to me and I want to work hard to make the site better so any and all suggestions are greatly appreciated. Contact…

Hi HN! We were trying to have our team adopt AI more and had the idea for "AI Bingo" - hands-on, mini challenges that resulted in something delightful and real. Our team members were obsessed, they were saying it was "weirdly addictive." People made AI-generated ASMR videos, n8n automations, games. Our email marketer built an Electron app using Claude Code. We were stunned - people were learning by doing AND having fun. So, we've spent the last few weeks building Made That, where anyone can do the same challenges and see other people's submissions. A lot of people feel a lot of existential…

Hi Hackernews, I’m Marvin from playrun.dev (https://playrun.dev), a platform for generating end-to-end tests for your application using just the URL. I recently worked on a project rewrite with a small team on a tight deadline. We needed to keep shipping while also writing tests for the application. We believed unit tests were a waste of time and decided e2e tests were the way to go, but doing so manually was still time-consuming and made shipping slower. Testing is one of those things we do as engineers that don’t have immediate ROI, and it was almost impossible to make the…

Hi HN, We're a small team building AI tutors out of India, and as you might guess, this means we spend a ton of time writing, testing, and refining prompts for LLMs. When we started out, we were using the OpenAI playground but things became tedious when we wanted to compare responses from different models. We tried a bunch of other playgrounds but found them lacking in some features so we built our own. Quick Links: Github: https://github.com/supernova-app/ai-playground Hosted demo: http://playground.getsupernova.ai Demo video:…

Hey Hacker News, For the last 2 months, I've been working on a testing agent to free developers from the endless maintenance of end-to-end tests. You just push up a PR, and our agent analyzes the code changes and automatically visits the preview to test things out like a real human! We also support describing tests in English (or even in the PR description), and we'll go through your site whenever you want via a GitHub action to test and make sure various core flows continue to work as expected. We are looking for early testers and are giving out a generous free tier! Just sign up on the…

For the last 6 months, I've been building ORUS Builder, an open-source AI code generator. My goal was to fix the biggest issue I have with tools like v0, Lovable, etc. – they generate broken, non-compiling code that needs hours of debugging. ORUS Builder is different. It uses a "Compiler-Integrity Generation" (CIG) protocol, a set of cognitive validation steps that run before the code is generated. The result is a 99.9% first-time compilation success rate in my tests. The workflow is simple: 1.Describe an app in a single prompt. 2.It generates a full-stack application…
