Hi there.
I'm Ted. I was born on [[August 22]]nd, [[1979]]. I went to the [[Rose-Hulman Institute of Technology]] in "lovely" [[Terre Haute]], [[Indiana]]. I tend to edit pages very sporadically, usually only when I for one reason or another think the page tends toward large amounts of falsehood. Such editing is typically of CS'y pages, such as [[LISP programming language|Lisp]] and the like.

Hi Ted! Nice to see you here. Welcome to Wikipedia! --[[LMS]]

Hi Larry. Thanks! Happy to be here.

Ted officially rocks by the way. -H

Begorra Ed !! Sorry to see an alterate future. [[Sonny Bono Copyright Term Extension Act|Bono]] anyone ?

Ed, do you think it would be possible to integrate your TeX hack with the wiki code so that one could type
$int_0^x t^2 dt$ and get an integral right away, in png produced by TeX? --AxelBoldt
:Possible? Yes. Going to happen? No. There are just way too many security issues that arise when we let the wiki software evaluate arbitrary code.
::With "arbitrary code" you mean "arbitrary (La)TeX" code? If so, are there really any dangerous <nowiki>TeX</nowiki> commands? Can you access the file system from withing <nowiki>TeX</nowiki>? --AxelBoldt
:::Yes, yes, and yes.
::::Ok, I wasn't aware of that. openout seems to be the problem. I just found a discussion of the very issue at http://math.albany.edu:8800/hm/emj/1995/msg00125.html. But I wonder if running the <nowiki>TeX</nowiki> interpreter under some nobody user in a tmp directory, using chroot(1) so that it can't see anything outside the sandbox, wouldn't solve the problem. Or can you also execute programs from within <nowiki>TeX</nowiki>, or access the net? --AxelBoldt
