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,…

Hi HN! We launched 10000resumes.com as a fun, visual alternative for developers to showcase their skills, roles, and social links in a grid format (inspired by the Million Dollar Homepage). Since our last post, we’ve added: Search functionality: Highlight profiles in real-time by skill, role, or name. Price drop to $0.19/spot: To reduce spam (free grids risked low-quality entries). Why repost? Previous posts were flagged for criticizing LinkedIn (lesson learned! ). We’re not here to bash platforms—just offer a quirky, browsable space for devs. Feedback drove major updates: search,…

Hey HN, I've just begun my solopreneur journey. I've been a "serial starter" - often starting projects and never seeing them through, and I have finally finished my first project! Maybe this sentiment resonants with some of you, let me know in the comments below I built this tool as a simple no-risk method for turning more visitors into customers by A/B testing your sale promotions and automatically displaying the promotion with the highest conversion rate. Did you know that increasing your conversion rate by just half a percent can have a dramatic impact on your sales without needing…

I built an archiver that tracked every HN item for 27 days (Dec 3-30, 2025) and captured 72k temporal snapshots to see how posts gain and lose attention. Key findings: - Early velocity (points/hour in first 2 hours) predicts final score with ρ=0.82. A simple classifier achieves 98.4% precision for viral prediction. - No Matthew effect: high-scoring posts don't get more upvotes per hour than low-scoring ones (ρ=-0.04). HN's gravity penalty actually works. - Yet extreme inequality persists: Gini=0.89, meaning bottom 80% of posts get <10% of total upvotes. Inequality without cumulative…

Hi Everyone, I've been working on FastMonitor.io solo for about a year now. FastMonitor monitors how fast your site is, and alerts you if it gets slower. Wanted to show it to you guys and get some feedback. Back Story: I built the basic tool kit for my previous startup - we were doing SEO and had very slow page speed across a wide variety of pages, so I ran lighthouse on an instance every day and put the results in the database and on a chart. This allowed us to chart our progress and celebrate when our pages got faster, or roll back / find the problem when things got slower. Feedback:…

Hi Hacker News! I’m Rashid, a first-year student at UT Austin and the person leading development of Rejourney, a web/app analytics and session replay tool. Recently, a handful of our users emailed us that they only care about a few user recordings (replays) that show conversion issues, and didn't want to waste time watching all the session replays they got. And no matter how many filters/smart capture rules we put in, the deterministic methods of choosing what to capture always missed important session recordings or overshot and recorded everything. Our users also used other…

ran this over the weekend. stack was Llama 3.2 3B running locally + Keiro Research API for retrieval. 85.0% on 4,326 questions. where that lands: ROMA (357B): 93.9% OpenDeepSearch (671B): 88.3% Sonar Pro: 85.8% Llama 3.2 3B + Keiro: 85.0% the systems ahead of us are running models 100-200x larger. that's why they're ahead. not better retrieval, not better prompting — just way more parameters. the interesting part is how small the gap is despite that. 3 points behind a 671B model. 0.8 behind Sonar Pro. at some point you have to ask what you're actually buying with all that compute for this…

Hi, we are working on a tool for speeding up test runs, by skipping tests unaffected by code changes. Effectivly, Saving 80-95% of the time, by skipping 80-95% of tests. We started a few months ago, and have managed to get into a few production CI systems. All our prospects and users are on holiday right now. So we decided to repackage and open-source for local test running. available here (https://github.com/nabaz-io/nabaz) under MIT license. One line change: pytest -v -> nabaz test --cmdline "pytest -v" Stalk us on GitHub, or just Star us. Ask questions, we'll answer in…

I submitted an earlier version of this a few months ago (as llama2.f90). At that time it had a lot of steps to run and was just a toy, now it's easy to run and is a competitive option for llm inference. See the motivation section for discussion and the `Performance` issue for an ongoing discussion about performance.

I built Resrap, a Go package that takes a grammar in ABNF format and generates infinitely long sequences of syntactically correct code...either completely randomly or with seeds for a deterministic generation. ABNF is a modified version of EBNF(https://en.wikipedia.org/wiki/Extended_Backus%E2%80%93Naur_f...) I made for this project, basically means you can specify when generating code 20% of lines will be if{} blocks and 50% will be while{} blocks which allows for more natural code generation, plus support for infinite generation of code. It’s very fast...it generated ~40…

Hi HN, I'm a solo dev and for the last few months I've been building Hikaro, a tool to find statistically significant trading signals for [e.g., US equities, crypto, forex]. I built this to solve my own problem: I was tired of backtests that looked great on paper but failed in practice. Simple metrics like "win rate" can be misleading, so I wanted a way to quickly tell if a signal's performance was genuine or just noise. Hikaro ingests daily market data and runs statistical analysis on various trading signals. The goal is to surface signals with strong properties, like: Low p-value: Evidence…

We are Anand and Raghav, the creators of HyperProphet (https://hyperprophet.com/), a tool to enable developers to compute thousands of forecasts in minutes using fbprophet without worrying about infrastructure. Scaling forecast computation is a hard problem, often costs developers in productivity. Even established organizations spend a lot of time trying address this, but often the outcomes are not easy to use and manage[1][2]. We spent the last few years building a demand planning product for CPG and retail in which we had to forecast thousands of time-series. Computing such…

I've given myself a 12-month coding challenge to create and validate six mini start-up ideas. Noticing a trend among developers to create and sell their boilerplates, I decided to start the challenge by making a (completely free & open-source) one for myself. I thought it might also be useful for others who like this tech stack. Since I plan to develop and validate ideas quickly during my challenge, having a solid boilerplate is going to be extremely helpful. Here's the stack: - SvelteKit + TypeScript (no NextJS...) - DaisyUI, TailwindCSS - Supabase Auth + Database And this is ready-to-go: -…
