( #3333=superdoc: print w/replies, xml ) Need Help??
The context is general knowledge. This all started when I read the passage I tersely quoted and blakem included in full. It's not to solve a specific implementation problem, but rather to ensure understanding so that I can avoid specific implementation problems.

I can't figure out why you would ever want to execute/eval untainted CGI input as-is

Yeah, that does sound dangerous. That's why the quoted material caught my attention. It seemes to imply that code could be evaluated without my express permission but instead simply because I put it in double quotes. That kinda freaked me out.

Thanks,

Ira,

    [ambrus]: Corion: the solution depends on who for. Some non-math presentations need to show lots of graphics or photos, with fine details and color. For those, blackboard or overhead transparencies aren't so good (yes, you can print on transparencies, but there's s
    [ambrus]: ome quality limits), but film projection or computer projector is fine.
    [ambrus]: A minority of math presenters are traditional and don't want to operate a computer. For them, handwritten overhead transparencies and blackboard are fine.
    [Corion]: BTW, has anybody seen the Microsoft Surface Studio thing live?
    [ambrus]: Some will operate a computer, but want to operate crazy unusable android-like GUIs. For those, printed overhead transparencies or simple slide editors and maybe even tablets are fine.
    [ambrus]: Some people like me are fine in learning how to use some custom user interface. For me, I might want to make some keyboard- controlled interactive live slide writer program, like I said in the hypothetical case when I have lots of years of free time for th
    [Corion]: ambrus: Some of my math professors delegated TeX-ing of the exercises etc. to their secretaries :) But they all had very neat handwriting and good blackboard operation anyway ;)
    [ambrus]: is.
