cheques are definitely still a thing in canada (companies still use them for one-off payments and landlords still use them to collect rent) and you can now deposit them by taking a picture with your phone.

    you will be pleased to know that the original text said "superlinear"; i just couldn't remember if the lower bound of multiplying a sufficiently sparse matrix was actually lower than O(n²) (because you could conceivably skip over big chunks of it) and didn't feel like going and digging that fact out. i briefly felt "superlinear" was too clunky though and switched it to "convex" and that is when you saw it.
