> you still thought it up on your own Back in the very early 2000s I had an idea for efficient backups that was essentially rsync, while tinkering with the thought I hit a block and started looking around for implementations of, or papers about, rolling checksums and such, and found rsync. I wasn't put out that my idea wasn't original - I was glad twofold because not only had someone done it better already (so I could just use it for the task as hand), but it at least confirmed that my thinking was very much on the right track.
