Making the two-dimensional one-dimensional
We often want to reduce something that’s inherently two-dimensional into something one-dimensional. We want to turn graph into a list. And we’d like to do this with some kind of faithfulness. We’d like things that are close together in 2D space to be close together in their 1D representation, and

To meet this critical need for AI skills and empower the next generation of talent, we at CodeSignal are thrilled
Read moreLooking back at Martin Gardner’s RSA article
Public key cryptography came to the world’s attention via Martin Gardner’s Scientific American article from September 1977 on RSA encryption. The article’s opening paragraph illustrates what a different world 1977 was in regard to computation and communication. … in a few decades … the transfer of information will probably be
Read moreBeing unambiguous in what you want: the software engineer in a vibe coding world
Quinn Slack, CEO and co-founder of Sourcegraph, joins the show to dive into the implications of AI coding tools on the software engineering lifecycle. They explore how AI tools are transforming the work of developers from syntax-focused tasks to higher-level design and management roles, and how AI will integrate into
Read moreFactoring RSA100
Earlier today I wrote about factoring four 255-bit numbers that I needed for a post. Just out of curiosity, I wanted to see how long it would take to factor RSA 100, the smallest of the factoring challenges posed by RSA Laboratories in 1991. This is a 100-digit (330-bit) number
Read morePairing-unfriendly curves
A couple days ago I wrote about two pair of closely related elliptic curves: Tweedledum and Tweedledee, and Pallas and Vesta. In each pair, the order of one curve is the order of the base field of the other curve. The curves in each pair are used together in cryptography,

This post will look at the time required to factor n − 1 each of the following prime numbers in Python (SymPy) and Mathematica. The next post will explain why I wanted to factor these numbers. p = 2254 + 4707489544292117082687961190295928833 q = 2254 + 4707489545178046908921067385359695873 r = 2254 +
