Fitting a parabola to an ellipse and vice versa

The previous post discussed fitting an ellipse and a parabola to the same data. Both fit well, but the ellipse fit a little better. This will often be the case because an ellipse has one more degree of freedom than a parabola. There is one way to fit a parabola

The ellipse hidden inside Pascal’s triangle

The nth row of Pascal’s triangle contains the binomial coefficients C(n, r) for r ranging from 0 to n. If you print out the values of a row for moderately large n the numbers appear to make an arc. Here’s are the numbers in the row for n = 100. You may be read the numbers if

Introducing: AI-Assisted Coding Assessments and Interviews

According to recent research from Stack Overflow, 76% of engineers now use AI copilots every day to help them write code, fix bugs, and solve problems faster. But there’s a problem: most technical hiring still evaluates candidates as if those tools don’t exist. Here at CodeSignal, we believe it’s time
