    • This is a really interesting hack. I love things that exploit the oddities of the landscape to do artsy/funky things; far more interesting than finding yet another way to trick…

  • Security and privacy risks such as phishing and spam

    From 3 comments

    • Or spearphishing. Send a secretary something that looks like a nice business proposal, then when she forwards it to her boss it's a link to some XSS attack.

    • Should be the other way around. You forward an email that's "obviously" spam, and then the abuse guys go "what do you mean, this is a regular project status update!"

Questions

  • Does Gmail cache images per user or per URL?

    From 1 comment

  • Tab damage counters in usenet signatures

    From 1 comment
