Introduction

We’ve done 10PRINT on a lot of machines.

But we haven’t done a comparison between Rust and C.

What is an LFSR?

An LFSR is a Linear Feedback Shift Register. It’s a simple way of generating a sequence of numbers that look random.

I was recently on a video call with a friend, throwing around some ideas for a new product. I mentioned adding large signed numbers in assembly and using two’s complement. He asked me what two’s complement was. I was a little surprised that he didn’t know. He’s been a Java programmer for more than 30 years. Java and Python programmers (and others like gasp Commodore / MicroSoft BASIC) don’t have a native unsigned integer type. The language takes care of the details for you.
