Yes sorry, my bad. Here's some more detail I found about the materials and manufacturing of these notes, taken from this PDF
"A contract for the supply of polymer material and associated security features was negotiated with Note Printing Australia (NPA), a wholly owned subsidiary of the Reserve Bank of Australia. The Bank has collaborated with the Reserve Bank to ensure that the supply of material and access to intellectual property are assured. The substrate itself will be supplied to NPA by the Australian company, Securency International, and the notes will be printed in Canada by two private sector security printers, Canadian Bank Note Company, Limited and BA International Inc., both based in Ottawa"
Dumped... quite literally! According to the Bank of Canada, worn out banknotes are put into landfill: "At the time of the study, the Bank of Canada had not chosen a specific end-of-life scenario for polymer bank notes. So, for the sake of modeling, the end-of-life treatment currently in use (landfill) for our cotton-based paper notes was assumed."
I don't suppose anyone happens to know where?
Does throwing insults somehow might you right?
You (and the mods who rated your comment "insightful") would do well to take an objective look at the facts here. If you'd bothered to RTFA, you'd realise that this is an apples to oranges comparison. The C++ code was optimised far beyond the Java code:
"E. Java Tunings: Jeremy Manson brought the performance of Java on par with the original C++ version. This version is kept in the java_pro directory. Note that Jeremy deliberately refused to optimize the code further, many of the C++ optimizations would apply to the Java version as well."
So while C++ might well be faster than Java, this article doesn't demonstrate that.
Blame the editors, I used a different headline when I submitted the article.
Let's not start a pissing match
