#8 Comment By Sale On March 24, 2008 @ 2:56 am

Hi Eli!
I discovered your site just before it goes down…happy to see it’s back, anyway I spent some hours browsing Google cached results to read your past articles…very interesting.

Now, just a question on this script: what kind of parameters do I need to pass? It may be a stupid question, but I’m not a python programmer…

#9 Comment By Futon-Matt On March 24, 2008 @ 5:27 am

I think this is a little out of my league, but I think the idea is cool.

#10 Comment By vlad321 On March 24, 2008 @ 6:55 am

thanks . ssuper

#11 Comment By anty On March 24, 2008 @ 11:07 am

Some comments in the code would be nice. A short introduction what the algorithm behind this is, would be perfect :)

After a short glance I guess the solution is, that the letters are always the same (pixelwise), so you are searching for letters from the left to the right buy comparing pixels?

#12 Comment By Sanchi On March 24, 2008 @ 11:34 am

cool….

but pythone is out of my list… anyways I am eagerly waitin for something, from u r box, which i can utilize on full fledged basis…

#13 Comment By Peter On March 24, 2008 @ 1:11 pm

This is awesome - but unfortunately well out of my league at the moment - just a matter of time me hopes though! Once again Eli you have pulled some great stuff out of the bag

#14 Comment By rob On March 24, 2008 @ 1:39 pm

Nice to see some new posts recently. Saw all of the drama on wf. To bad it took someone going after you server, though.

Anyway, hope to see more, and the seo empire pt. 2 post soon, too.

Wow, how can this be ?

#36 Comment By Gadgets4nowt On April 7, 2008 @ 5:02 pm

If Delicious offered you money to devise a captcha that wasn’t crackable, would you do it..and for how much?

#37 Comment By shoban On April 7, 2008 @ 10:37 pm

Nice article!!!

#38 Comment By Jagdu On April 9, 2008 @ 10:50 am

Hilarious! At least you’re making as many friends as enemies along the way. I’d second Gadgets4nowt’s questions about creating a captcha.

#39 Comment By Pay Per Install On April 10, 2008 @ 4:24 am

Well it might bring more secure captcha…

#40 Comment By Homebuilder On April 10, 2008 @ 1:56 pm

LOL! I read a little bit into the controversy that cracking captchas has caused. Some of those forum posts are pretty amusing, I like the fact that you redirected to the whitehouse.gov site to get even!

#41 Comment By Kyle On April 10, 2008 @ 11:40 pm

Thanks a lot for this - and good to see you back posting!

#68 Comment By Max M On May 23, 2008 @ 12:52 am

Thank you, i use this code in future.

#69 Comment By hax0r On May 27, 2008 @ 7:58 am

This one at delicious isnt so bad to crack because:

–the letters are sharp without any garbage over them
–you can easily get rid of the background by setting an RGB threshold value
–the same rotation angle applies to all letters in the word
–the rotation angle is always 0, +15 or -15, as opposed to being completely random
–Only lowercase symbols are present. No caps or numbers. This greatly enhances the success rate.

The next one to tackle down that has most of these difficulties (randomly rotated,caps, numbers,random lines crossing and garbage over symbols..) is the captcha at digg! I’m working on it but it’s hard to obtain sharp letters because of all the line garbage.. I tried the one at delicious with my tools and it got around 50% success of guessing the captchas. Individual letter guessing success is pretty good near 88%

Based on how good your success rate for your script is, a way to improve it:
notice that no two vowels are next to each other on delicious captchas, also no two consonants either. So on top of everything you do you can check for that too. I haven’t tried that tho. keep up the good work

#70 Comment By Forumistan On June 7, 2008 @ 8:23 am

LoL, Now i just need to convert it to PHP

I’m working on it but it’s hard to obtain sharp letters because of all the line garbage.. I tried the one at delicious with my tools and it got around 50% success of guessing the captchas. Individual letter guessing success is pretty good near 88%

#199 Comment By shoes On April 6, 2011 @ 10:16 pm

Northwest Indians told early explorers about the fiery Mount St. Helens. In fact, an Indian name for the mountain, Louwala-Clough, means “smoking mountain”. According to one legend, the mountain was once a beautiful maiden, “Loowit”. When two sons of the Great Spirit “Sahale” fell in love with her, she could not choose between them. The two braves, Wyeast and Klickitat fought over her, burying villages and forests in the process. Sahale was furious. He smote the three lovers and erected a mighty mountain peak where each fell. Because Loowit was beautiful, her mountain (Mount St. Helens) was a beautiful, symmetrical cone of dazzling white. Wyeast (Mount Hood) lifts his head in pride, but Klickitat (Mount Adams) wept to see the beautiful maiden wrapped in snow, so he bends his head as he gazes on St. Helens.
