We eliminated pennies in Canada in 2012 and the transition was a non-issue. The vast majority of retailers would round cash transactions to the nearest $0.05, but a few would round down to the nearest $0.05 in favor of the customer. https:

Yeah. The article tells a good story and I agree with it. I even bought an Athlon 64 CPU back in ~2004. What I want to add to the story is that when Intel Core 2 came out (and it was an x86-64 chip), it absolutely crushed AMD's Athlon

Managing your own buffer of object slots, allocating from them, and using integer indexes instead of typed object pointers - all of these are a small amount of extra work compared to using native language features. I'd like to point ou
