How hard is constraint programming?

I’ve been writing code for the Z3 SMT solver for several months now. Here are my findings. Python is used here as the base language. Python/Z3 feels like a two-layer programming model—declarative code for Z3, imperative code for Python. In this it seems reminiscent of C++/CUDA programming for NVIDIA GPUs—in

Life in the Fastlane: SDK tools built with developers in mind


On this sponsored episode, Ben and Ryan talk to Sunny Patel, Staff Software Engineer at PayPal, and Kyle Prinsloo, a developer and a PayPal partner, about all the ways that Fastlane by PayPal makes developers’ lives easier. They explore the needs that both merchants and consumers have for creating a

Celebrating 1 million practices completed on CodeSignal Learn

Today, we’re beyond excited to celebrate an incredible milestone: 1 million practice sessions completed on CodeSignal! Over just a few months, our dedicated community of learners have put in thousands of hours of work to sharpen their skills, build new skills, and advance their careers.  Earlier this year, we launched

How can you get your kids into coding? We asked an 8-year-old.

Ben welcomes Ricky Robinett, VP of Developer Relations and Community at Cloudflare, and his eight-year-old daughter Fay for a chat about how AI tools are helping new developers get started and how to encourage your kids to try coding.

Chris’ Corner: Interesting CSS Explanations

Let’s do CSS stuff this week. Why not — kinda my thing. Did you know Alvaro Montoro has a whole site of comics on the subject of CSS? There is a lot of satire in there, which I really enjoy. So they changed CSS nesting a bit. I heard that

Band-limited expansion

The band-limited expansion of the function f(x) is given by where sinc(x) = sin(πx)/πx. This is also called the sinc expansion, or the Whittaker cardinal after its discoverer E. T. Whittaker [1]. This is called the band-limited expansion of f because each term in the infinite sum is band-limited, i.e.

Delay differential equations

Sometimes the future state of a system depends not only on the current state (position, velocity, acceleration, etc.) but also on the previous state. Equations for modeling such systems are known as delay differential equations (DDEs), difference differential equations, retarded equations, etc. In a system with hysteresis, it matters not

Laplace transform inversion theorems

The way Laplace transforms, as presented in a typical differential equation course, are not very useful. Laplace transforms are useful, but not as presented. The use of Laplace transforms is presented is as follows: Transform your differential equation into an algebraic equation. Solve the algebraic equation. Invert the transform to obtain your
