My mom and I used to take turns reading the code listings from magazines like Compute! and RUN to each other and typing them in. It took forever. I definitely find it harder to do that with punctuation heavy languages these days (not that I'm typing much code in from magazines anymore).

This is a classic example of how the culture of home parenting, and individual choices made by the parent, has a big impact on kids. Having your mom , of all people, reading code listings from a software magazine, typing them into a computer with you, pretty much puts you into the top 1% percentile in terms of parental engagement in their child's intellectual development. Race itself is irrelevant compared to this. N…

True, but race and nationality are pretty relevant as to whether you have a mom who has convenient access to software magazines and computers to type the code into.

I want to make sure a person votes only once. But if they want to game the system fine as long as they are willing to submit a captcha For another website, I used to store the IP address and do checks but for a simple system that seem to be overkill. All of the websites have no user accounts. Is there another way to do this? Where you want some voting to happen but with no user accounts. And you want it to be dirt si…

Ah, I get it. You are using a captcha not for its resistance to automation but as a way to make a user pay (with time) for an action. If you start with the assumption that no one will try to attack your site, then you don't need a captcha at all. You can give the user any annoying/time-consuming task (e.g. "click a square ten times"), or you can insert an inconvenient delay in vote submission. However, people may obj…

Thanks, these are great ideas. I never thought of doing this way.

The site dos not take in user generated content that is immediately displayed. The data is first curated and verified so the attack will be a bit harder. So there is fresh (delayed) content constantly.

That is exactly the reason of the captcha: to give a person something to do that wastes a bit of their time and that is familiar to them.

Yes, in other sites I have used captchas to prevent automated abuse.

I don't think mkramlich was meaning to imply otherwise, because the relevancy of parents' involvement doesn't just apply to technology. Engaged parents who involve their kids in engine rebuilding or animal husbandry or child rearing or anything else that requires years, effort, and guidance to master are most likely are in the top 1% in terms of intellectual development.

Technology and computers wasn't my mom's hobby or profession (she's actually a seamstress -- and I learned the basics of sewing from her) so it wasn't like she was introducing me to her interests; however, when my son gets older (out of diapers), I plan on spending time with him teaching about my major interests and learning new things with him that's he's interested in, independent of what that may be.

But the logic of the CAPTCHA is "if you get this right, then you are human". Makmanalp was suggesting "if you get this wrong, you are not human", which does not follow logically from the CAPTCHA rule. It is an example of "Denying the antecedent", or the inverse error: http://en.wikipedia.org/wiki/Denying_the_antecedent

Who is to say that "if you get this right, then you are human" is the valid premise? I'd argue that the correct one is "If you're human, you get CAPTCHAs right". :P

Just to be pedantic: CAPTCHAs are a test for being human so human-ness has to be the consequence of some condition. Your premise is therefore an incorrect framing of the CAPTCHA test.
