CDIC protects deposits in some Canadian institutions up to $100,000 per category, per bank.

CIPF protects investments (stocks, bonds, mutual funds, etfs) held on your behalf by some Canadian institutions. CIPF protection covers up to $1-million of RRSP accounts, plus $1-million worth of RESP accounts, plus $1-million worth of other accounts, per person per investment dealer. -- money

I interpret the following to mean that when you're logged in and view a photo at a url, that url has a short lifespan. But if you right-click and copy the image url (and perhaps if its in a public album) then the url is marked to live forever. This article says that the photo isn't placed at that URL until you ask for it. Google Photos normally pulls its images through a more complex back-end system, but when a user right-clicks on one of their own images, Photos responds by placing the image at the designated public URL. "There are enough combinations that it's considered unguessable," says Aravind Krishnaswamy, an engineering lead on Google Photos. You can give it to a friend or pull it through an automated scraper, and it will load just the same. For Google, that's a feature. "The value of URLs is that they're universal," says Vincent Mo, another lead engineer on Photos. -- web
