12/8 ALL HAIL EMPEROR GORE!
\_ Joe "Palpatine" Lieberman is the emperor. ALGOR is a robot.
Seriously, look at a picture of liberman and palpatine from
The Phantom Meaance ... just a slight hair cut diff.
\_ motd formatting god was here.
\_ You cannot resist the powuh of the dahkside!!
\_ There are always two, the master and the apprentice.
\_ Like Bush Jr. isn't a tool for the Repub. party,
a pupet to give BJs to Cheeny and the Oil Interests.
Microns worse than selling the country out to China.
\_ What's a "pupet"? And even if your alt.conspiracy oil
interest nonsense had a basis in reality, how do you see
opening oil fields in Alaska as worse for the country
than handing it over to a foreign power such as China?
If you're going to spew leftist noise on the motd, please
at least make some bare minimal effort to make sense. Or
would that be a logical paradox for you?
\_ if someone responds to a star wars quote with
anything remotely serious, and you respond seriously
you are just as much of an idiot for responding.

drivel required a response, old ben. |

n12/8 Is there such a detacheable X terminal? I would like the ability to
detach my current X and continue working at home... is that feasible?
\_ vnc
\_ There are a few things that will do this: the vncserver for X
will give you a detachable, reattachable X session; but it's not
encrypted, but you can always ssh to the machine and do a
vncviewer localhost. "xmove" has a form of this, and there's also
at least one more whose name escapes me. In reality, I've never
found any of these very useful, probably because I've never had
a very low bandwidth X program that was essential to detach (just
end up using "screen" usually..) --dbushong
\_ huh? Vnc is plenty damned fast.
\_ It's about as fast as running the apps remotely not in VNC
...which may be fast enough for you.. --dbushong
\_ I've played netrek over VNC. It's faster than that.

12/8 Is UC Hastings a top-ranked law school in the nation? A friend of
mine who had ~3.0 GPA in some non-engineering major in Cal got into
Hastings. I thought that school was much harder to get in.
\_ It's not top-ranked, maybe top-25.
\-LSAT probably counts for a lot. --psb
\- why does it matter? are you jealous that your friend
got away with it?
\_ Hastings is usually ranked around 30-50 in most surveys that
I have seen and I have never seen break top 20. Don't be too
impressed, partha is correct: one lucky LSAT score counts for
more than GPA. The reason is that while GPA varies from school
to school or even major to major, everybody takes a similar
version of the LSAT. I know law professors and they
tell me as much - LSAT is the weeder. -fab
\_ How does one get 'lucky' on the LSAT?
\_ You take guesses at answers, that sort of thing... -fab
\_ You should ask yermom what it means to get 'lucky'
\_ I hit a homerunwitha history major who got admitted to hastings.
Shows you what type they let in
\_ uh, how? Because s/he had sex with someone? Isn't that true
of people who go to every school? Isn't that true of you?
\_ Some bimbo who wanted an easy lay she could get off on and
then forget about? Cheap stress free sex? History majors
need it too, ya know.
\_ Woohoo! cheap, stres-free sex. there is a god
\_ there is a god, he just hates you.
\_ there is a god, SHE just hates me.
\_ The point being she scored him. He got used.
\_ He got laid, that's a rare occurrence for
any sodan. Used or unused, sex is sex.
\_ Yeah, I don't see the problem.
He got laid, she got laid, everyone
wins. -bclinton
\_ All male geekdom must mourn this event.

12/7 How many people cheated in 162 and got caught?
\_ A little worried about our 162 grade, eh?
\_ Man, people who get caught cheating just haven't gotten the art
of it down. Should've been practicing and perfecting it in high
school (not that you needed to cheat in HS)
\_ I'm not sure how one would beat a histogram-cheat-detection
scheme. Anyone have any ideas? Other than rearranging
lots of code. And if you do that, why not just do the
project? --PeterM
\_ how does a histogram-cheat-detection scheme work?
\_ I'm not sure, exactly. This is how I imagine it works:
do "wordcount" on all the symbols in the program.
Then you sort the symbols in order of number of
occurrences. Plot a graph of this. Programs
which have just had one symbol substituted for
another will have identical graphs. --PeterM
\_ Hmm, that's easy to break. Just introduce a lot
of redundant local variables with different names
in many routines. Also, rename your local vars
"i" in all routines to "n" for some routine and
"x" for other routines.
\_ Uh huh. What if I look at keywords too?
A histogram of those. Now you have to
rearrange all the control structures too.
This is beginning to sound like a lot of
work: you'd have to do all this rearranging
and substituting and test the result.
--PeterM
\_ just make sure you send the code through
a preprocessor first, to make sure the
keywords aren't being substituted with
#defines
\_ This only breaks one histogram method. There
are probably multiple ones used.
\_ Call graph topology comparison
\_ I suspect that any kind of polynomial time
code comparison program could be defeated
without much trouble. I say this because of various
results in complexity theory about determining
equivalence. For example, determining equivalence of
Turning Machines or Context Free Grammers is
undecidable. Determining equivalence of regular
expressions (or finite automata) is PSPACE-complete.
(Recall that PSPACE is a harder class than NP).
Since programs running on regular computers
(not Turing Machines) are actually finite automata,
if you come up with an algorithm to efficiently compare
programs then you can solve a hell of a lot of other
more important problems. In practice, you can probably
defeat most program comparison tools by writing an
obfuscator program. One possible obfuscation
technique would be to merge and expand functions in a
random manner, and then randomly rename all symbols
including the function names. Of course, cheating
is unethical, but the comparison problem is an
interesting thing to think about. -emin
\_ as mentioned below, one would probably focus
on heuristics that work on typical undergrad-
LOT of results out there, and even if you CAN cheat
a finite-dimensional analysis of infinite-dimensional
spectra, it's extremely difficult to do so if you
don't know which dimensions they are looking at.
While MOSS may not be all that great, it's
presumably non-trivial. Listen to peterm above, he's
basically right. Oh, and another thing -- the class
of all poly-time code comparisons is way too huge and
it should be relatively trivial to prove that not
only is it not "easy" to defeat a random sample of N
poly-time tests if you don't know which ones they are
using, but it's probably complete for BPEXP or
something equally intractable. -alexf
generated, human-readable code. further, it is
likely one would need to convert to an abstract
normal-form that is easily compared to check
the N-way cheating problem efficiently.
\_ What 172 fails to mention is the practical
inapplicability of most of these results. There are a
LOT of heuristics out there, and even if you CAN
cheat a finite-dimensional analysis of
infinite-dimensional spectra, it's extremely
difficult to do so if you don't know which dimensions
they are looking at. While MOSS may not be all that
great, it's presumably non-trivial. Listen to peterm

BPEXP or something equally intractable. -alexf
\_ What emin means to say is, "The cheat program is a
crock of shit. It's just a slightly improved
version of 'diff' so don't let it bug-a-boo you."
They've been talking about their mythical anti-cheat
program for years but I've turned in tons of out
right stolen code with no changes and got good
grades.
\_ you are a hollow man. You also are lucky:
the methods described above are capable of
catching THAT. Your empty mind will betray
you when you meet real challenges, and
your luck will fail.
\_ Luck? I grabeed shit off the printer and out
the trash, retyped, turned in. A. Did it
plenty of times. I could do the work, I just
didn't feel like wasting my time on it. I
went drinking and got laid. What were you
doing in the lab all night?
\_ Uh huh, and if you'd been caught, you'd
be expelled and getting your
degree from DeVry. Luck. And lazy-ass
readers/Profs.
\_ Unfortunately, the way the
work structure operates, you
can cheat your way through
the cs program at Berkeley
and yet get by in the real
world with at least a $50K
salary or even better. I opted
to get out rather than live
the lie. Some people don't
have those compunctions, but
who knows? Maybe they'll get
what's coming to them, and maybe
they won't.
\_ People have gotten caught cheating
but they didnt get expelled. it's
usually a big empty threat.
\_ depends on what they're caught
cheating on, and how many past
offenses they've had.
\_ Yes, of course the worst
offenders get booted. I did
not say nobody gets expelled
but usually it's a big
empty threat. MOST cheaters
do not even get an F for
it.
the course. This is far
different from being exiled
to DeVry for being caught.
\_ and would this obfuscator be able to produce
human-readable code? if a person spent even a
small amount of time looking at it, wouldn't it be
pretty apparent that the variable and function
names make no sense? (I guess the obfuscator
could use a thesaurus and randomly pick synonyms,
but I doubt that'd produce reasonably
intelligible results either.)
\_ This requires that someone actually look at
the code. Lazy readers and profs permitted the
cheater above to get by. No cheat-detection
method has a chance of working if it is not
applied, the common case, I imagine. -PeterM
\_ obviously, but I meant that machine-obfuscated
code should be pretty easy to recognize, even
if a reader only spends a minute looking at
it. Is a minute too much to ask for?
(rhetorical question; I know the answer is
"yes".) |

12/7 Do I have to compile my own X server? How? This is for Solaris 5.6
mylinux:/home/tom% lbxproxy :5 -display localhost:0
\_ Why would you name your solaris box "mylinux"?
X server doesn't have LBX extension
\_ ssh -C, while not quite as good, is a whole lot easier to use
than lbxproxy.
\_ 1) There is no Solaris 5.6 (SunOS 5.6 == Solaris 2.6)
2) Xsun supports LBX only on Solaris 7 (SunOS 5.7) & later
(Solaris 7 11/99 or previous versions plus patches)
3) You can compile your own X server with LBX support by downloading
the source from http://X.org, but unless you're running on older
hardware, it probably won't support your graphics adapter.

12/7 Eh, why are some virtuals set to 0 (pure virtual) and some are not?
\_ defining as virtual = 0 to create an interface definition or
abstract class
\_ Yes. In particular, pure virtual functions are a signal to both
the compiler and client code that this class is not expected
to be instantiated, only inherited from. It also requires any
child classes to provide the method, but doesn't provide a
default implementation. There are many situations where this
is exactly what you want. You may not really get this until
you're trying to make a framework of code that other people
are expected to use, but not modify... -mogul |
