Building a Better CAPTCHA

MP3Chuck Re:No workarounds? Really? (197 comments)

"Do they enter random text or put in URLs where they shouldn't?"

A (somewhat) common thing to do is have a form field hidden with CSS. Spam bots rarely, if ever, parse CSS ... so you hide a "Website" or "ICQ" form field (who uses ICQ anymore, anyway?) and if it's filled in you ignore the submission entirely.

Or, you have a form field labeled "Leave this field blank." Spam bots will usually fill in all available fields so, again, if it's got a value you just ignore it.

Ubuntu Download Speeds Beat Windows XP's

MP3Chuck Re:Temporary boost in download speed? (515 comments)

I'd mod you up, but I feel compelled to reply ... since I'm amazed nobody has mentioned this.

I just signed up for Time Warner 'net myself, and when the dude was checking the signal he mentioned something about how there's a 25Mbit "boost" that people get at random. I didn't get a chance to ask many questions about it, but he said that it wasn't just an ISP-level cache ... you're actually given 25Mbit of bandwidth for a breif amount of time. That could very well be what we're seeing here, as the numbers seem to align.

Submission Text Formatting Tips

We support a small subset of HTML, namely these tags:

  • b
  • i
  • p
  • br
  • a
  • ol
  • ul
  • li
  • dl
  • dt
  • dd
  • em
  • strong
  • tt
  • blockquote
  • div
  • quote
  • ecode

"ecode" can be used for code snippets, for example:

<ecode>    while(1) { do_something(); } </ecode>
