- Abusing Amazon Images — decoding and doing fun things with the Amazon images API. The cool thing (if you want to generate unlikely Amazon images) is that you’re not limited to one use of any of these commands. You can have multiple discounts, multiple shadows, multiple bullets, generating images that Amazon would never have on its site. However, every additional command you add generates another 10% to the image dimensions, adding white space around the image. And that 10% compounds; add a lot of bullets, and you’ll find that you have a small image in a large blank space. (You can use the CR command to cut away the excess, however.) Note also that the commands are interpreted in order, which can have an impact on what overlaps what.
ENTRIES TAGGED "prime numbers"
This morning, Tim Bray tweeted about a post on prime numbers and Benford’s law. To cut the esoterica short, one of the big problems in prime numbers is that people don’t know how they’re distributed. This post suggests that Benford’s Law describes the distribution of the first digit of prime numbers. One of the comments asked an important question: is this really just an artifact of base 10? Math really doesn’t “know anything” about bases, so if this idea doesn’t generalize to bases other than 10, it doesn’t mean much.
