i still don't consider this news - i stumbled upon this the first time i had to implement multi-precision multiplication - its a standard technique. if someone posts linked list wiki article is that news because for some situations arrays are faster and in others trees are?

I also don't consider it news. Unfortunately, it's hard to tell if something is news to everyone, news to most people on HN, and news to a few people.

For me this falls into the category of "new to me, but it's old news if you're in the field."
