Re:Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars? on Tuesday September 21, 2010 @02:09PM (#1713496)
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.
Re:Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars? on Monday September 20, 2010 @03:31PM (#1710206)
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.

Re:The Angry Rich on Monday September 20, 2010 @02:18PM (#1709913)
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.

Re:Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars? on Monday September 20, 2010 @02:04PM (#1709836)
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.

Re:Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars? on Monday September 20, 2010 @11:40AM (#1709204)
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.

Re:Revisiting Solid State Hard Drives on Wednesday September 15, 2010 @12:13PM (#1694728)
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

Re:Lycos, poster child of Internet boom, sells for just $36M on Monday August 16, 2010 @05:47PM (#1609399)
It was sold for $12.5 billion (in stock) to Terra Networks (Telefonica) in May 2000

(Telefonica stock is worth more now than it used to in 2000)

So it looks like Lycos investors made a brilliant move.

Re:Graph visualization on the web with Gephi and Seadragon on Monday July 26, 2010 @01:48PM (#1548696)
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.

Notice how that the chart scale doesn't start with zero. In reality they win maybe 10-15% in speed, but they have all the crap overhead to support and manage.

Wow, that's very expensive. I'd prefer PayPal or Google Checkout.

Re:Dubai in 45 gigapixels on Monday May 03, 2010 @03:24PM (#1315799)
Zoom all the way in. The quality is so bad, you can downsample it by the factor of 2 (or maybe even 4) without any detail loss, (which reduces the number of pixels by the factor of 4, or 16 respectively). So it's really a 3-10 gigapixel panorama.

Also notice ugly vertical stripes in the sky area. I'm not sure what caused that.
