I know a del.icio.us employee (one of the first 10) who got completely ripped off on his equity.

You have no idea how spam works. A bot isn't just one user trying to enter "cat" repeatedly. Botnets send requests from thousands of different IPs. You wouldn't know which ones are real users, and which ones are bots.

My spam script would always answer "cat", so among 8 options (cat, dog, house, drum, road, tree, book, horse), I'd get a 12.5% success rate.

Plus you constantly have to update your image library, which a huge pain.

Also, recognizing 10,000 images will take me around one day and less than $1000 with Amazon turk, thus giving me a perfect 100% success rate. After that you would have to completely renew your image database.

Nobody is being taxed on the cash one has in his bank account. You're taxed on the income your cash generates.

So cut the crap.

So you think it's great that rich get taxed at 15% and the poor/middle class at roughly 30-40%?

I'm pretty sure among you and Krugman, you're a hack.

Still doesn't make sense.

If you display 10 random animals (or shapes), and ask a user to pick the right one, a dumb spam script would have a 10% success rate.

If you display one image of an animal and give 10 possible answers, a dumb spam script would have a 10% success rate.

You have no idea what you're talking about.

> show a picture of an animal or a shape and ask what it is,

Ok, so let's say you come up with pictures of 20 different animals. A spam script that picks the same answer every time will have a 5% success rate.

> or even just ask a simple math problem or riddle in writing.

Computers are way better at solving most math problems than people.

C300 is definitely NOT the fastest SSD drive. There are a few that are much much faster.

1) FusionIO ioXtreme = 670/280 MB/s

2) FusionIO ioDrive = 770/750 MB/s, 140,000 IOPS

3) FusionIO ioDrive Duo = 1500/1500 MB/s, 261,000 IOPS

4) RamSan-440 = 4 GB/s, 600,000 IOPS

5) NextIO vSTOR S100 = 5.5/6 GB/s, 2,200,000 IOPS

There are many more listed here: http://www.storagesearch.com/ssd-fastest.html

That's horrible. Instead of drawing graphs on the client side, you're pushing insanely large number of images to the browser. It makes sense for google maps, not for graphs.

Plus you can't do any animation, changes to the graphs on the fly.
