Error in Ramanujan’s approximation for ellipse perimeter

Ramanujan discovered an incredibly accurate approximation for the perimeter of an ellipse. This post will illustrate how accurate the approximation is and push its limits. As with all computations involving ellipses, the accuracy of Ramanujan’s approximation increases as eccentricity increases. But the error increases slowly, and in fact is bounded.

AI vs. human engineers: Benchmarking coding skills head-to-head

We are excited to introduce our AI Benchmarking Report, where we compare the software engineering skills of several popular AI models. Over the past few years, we’ve been helping our customers embrace AI in hiring, including building an AI-assisted assessment experience. To do that, we had to start by understanding what

The Cauchy distribution’s counter-intuitive behavior

Someone with no exposure to probability or statistics likely has an intuitive sense that averaging random variables reduces variance, though they wouldn’t state it in those terms. They might, for example, agree that the average of several test grades gives a better assessment of a student than a single test

Arithmetic, Geometry, Harmony, and Gold

I recently ran across a theorem connecting the arithmetic mean, geometric mean, harmonic mean, and the golden ratio. Each of these comes fairly often, and there are elegant connections between them, but I don’t recall seeing all four together in one theorem before. Here’s the theorem [1]: The arithmetic, geometric,

Looking under the hood at the tech stack that powers multimodal AI

Ryan chats with Russ d’Sa, cofounder and CEO of LiveKit, about multimodal AI and the technology that makes it possible. They talk through the tech stack required, including the use of WebRTC and UDP protocols for real-time audio and video streaming. They also explore the big challenges involved in ensuring

Advice from CodeSignal CEO, Tigran Sloyan, on prepping for tech interviews & assessments

Taking a technical assessment is a common first step in the engineer hiring process—it allows employers to gain an early signal of candidate skill and gives applicants the opportunity to show off what they can do, regardless of their education or experience. Still, a coding assessment can be intimidating for
