SPAM.

Guys, cmon, this is obvious book spam. There's even an affiliate link at the bottom

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

olegkon Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars?

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.

olegkon Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars?

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.

olegkon The Angry Rich

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.

olegkon The Angry Rich

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.

olegkon Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars?

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.

olegkon Goodbye (Crummy) CAPTCHAs. Hello Ad Dollars?

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.

olegkon Revisiting Solid State Hard Drives

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

olegkon The Web Is Dead. Long Live the Internet

This is stupid. Of course video percentage will grow. Every time you double the resolution, you quadruple the amount of data you have to transfer.

olegkon Lycos, poster child of Internet boom, sells for just $36M

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.

olegkon Graph visualization on the web with Gephi and Seadragon

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.

Does it work at 1000 MPH?

Plus they are talking about voice data, not just the coordinates.

Except that most people don't have internet access. Only like 25% of the world population.

olegkon Google Maps - Diffable: only download the deltas

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.

Once burglars figure out what it is, they will use it to their advantage.

Your PNG compressor is garbage.

Also don't forget that the path string will be gzipped (to around 220 bytes).

Your profit margins must be insane if you can afford to give 6% of your earnings away for some glorified credit card processing.

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

You seriously think the rest of the country is different?

olegkon Dubai in 45 gigapixels

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.

Your bounce rate didn't change. The title is very misleading.
