That was probably just a random student who learned some fun stuff in Security class and slept through the Ethics lesson. I can't speak for UMich, but security research at my university (NC State) has a very strict "don't attack civilians" policy.
> hosting a .com commercial site
First off, .com sites are not necessarily commercial. Second, this isn't a commercial site, it's an informational page about a recently discovered TLS vulnerability.
(This was prompted by the question of what Apple's Web site runs on if they don't make servers any more.)
(Disclaimer: This is based on Raleigh, NC's traffic lights. I don't know what level this is standardized at.)
But also I'm super-excited about the rest of the schedule. There are 36 talks that I'm really interested in seeing, and I don't think that's even physically possible. So I guess I have to decide which ones I'll have to settle for watching on pyvideo.org.
She freaks out a bit, I freak out a lot. We're both worried that something really bad happened, then I realized that DEAD is actually a number in hex. I look through the data segment, and I see a AD DE in there (yay Intel byte reversal!).
I check through the code a bit, and even though it looks like the data segment is being initialized properly, it's still reading from the Program Segment Prefix. So, I find the Wikipedia article on the PSP and see that address 05h in the PSP has a cross-segment jump to CP/M compatibility code.
But, there's nothing at address DEAD (at least, nothing sensible). So I go searching through the DOSBox code for that string, and I find these lines:
// far call to interrupt 0x21 - faked for bill & ted
// lets hope nobody really uses this address
sSave(sPSP,cpm_entry,RealMake(0xDEAD,0xFFFF));
As it turns out, because DOSBox doesn't implement CP/M compatibility, they simply made it jump to DEAD instead, just to make sure that if anyone tried running a CP/M program they would get the picture. And the assembler just happened to put the variable in the right place that the load pulled the DEAD instead of random nonsense.I can only imagine the problems that can manifest when you're dealing directly with hardware, and don't have access to commented source code.
They're not opposing the use of the word "he," they're opposing him saying "no, go away, I don't see any reason someone could take offense" when the issue was pointed out instead of "thanks for the patch."
