The Wayback machine-slightly offtopic

There is a wonderful website ( that makes a backup of websites. It even has one of this blog, taken on April 30th. It’s remarkable.

The reason I mention it is because I was looking at the backup of, a website that I managed (curated, wrote tutorials etc.) on “Programming in C, C++, C#” (and even Go) between 2006 and 2013.  One of the things I ran there was a set of programming challenges and by the end I’d done a whopping 70 of them. I came up with the idea, published it, then adjudicated entries.

This page has a list of 65 of them.  There may be more from a later date but no more than 70.

As I can now gain access to most of them, I’m going to rerun a few here. starting with the first which I’ll publish tomorrow.
