What it does
Track revenue, EPS, margins, and cash flow quarter by quarter. Score every company with Rule of 40 and composite signals. Free, no sign-up required.
Revenue, EPS, margins and cash flow — pulled from filings, recomputed each time a company reports. Tesla has 420 robotaxis registered in Texas; our city model projects 2,500 to 14,100 vehicles by year-end, with a 7,550 midpoint. Vista Energy grew trailing revenue 78% and scored 86 on the Rule of 40, though eight of 14 stored quarters burned cash. Zscaler scored 41.4 on the Rule of 40 for April and 52.7 trailing, but its $0.48 trailing GAAP loss leaves no P/E. GitLab scored 78.7 on the Rule of 40 for April and 51.1 trailing, while its consensus target sat $7.63 below the close. SpaceX is preparing to cast gas-turbine blades in Texas. Musk's APR fleet exceeds 1.1 GW, but that is only about…from r40.io

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
